How is your mind different from everyone else's?

31 Post author: Kaj_Sotala 05 December 2011 08:38AM

Partially to help reduce the typical mind fallacy and partially because I'm curious, I'm thinking about writing either an essay or a book with plenty of examples about ways by which human minds differ. From commonly known and ordinary, like differences in sexual orientation, to the rare and seemingly impossible, like motion blindness.

To do this, I need to start collecting examples. In what ways does your mind differ from what you think is the norm for most people?

I'm particularly interested in differences - small or large - that you didn't realize for a long time, automatically assuming that everyone was like you in that regard. It can even be something as trivial as always having conceptualized the passing of years as a visual timeline, and then finding out that not everyone does so. I'm also interested in links to blog posts where people talk about their own mental peculiarities, even if you didn't write them yourself. Also books and academic articles that you might think could be relevant.

Some of the content that I'm thinking about including are cultural differences in various things as recounted in the WEIRD article, differences in sexual and romantic orientation (such as mono/poly), differences in the ability to recover from setbacks, extroversion vs. introversion in terms of gaining/losing energy from social activity, differences in visualization ability, various cognitive differences ranging from autism to synesthesia to an inability to hear music in particular, differences in moral intuitions, differences in the way people think (visual vs. verbal vs. conceptual vs. something that I'm not aware of yet), differences in thinking styles (social/rational, reflectivity vs. impulsiveness) and various odd brain damage cases.

If you find this project interesting, consider spreading the link to this post or resharing my Google Plus update about it. Also, if you don't want to reply in public, feel free to send me a private message.

I am:
* Anhedonic
* High-functioning autistic
* Polyamorous
* D/s (service-dominant & sexual sadist)

-- Amongst other things I am actually unable to "just allow" myself to feel things. If I lack a conscious avenue for expression of emotions, I find myself unable to do so: without a 'bridge' to cross from "in my head" to "the outside world", the sentiments or desires just don't have anywhere to go. Others have often given me advice targeted at getting me to "stop repressing my emotions", and these things have universally failed to recognize my issues in that regard. One of the things I will always be grateful to my ex-primary for was her ability to enable me to learn how to handle new situations and inputs that were markedly unfamiliar to me: if I did not have a -- for lack of a better term -- "subroutine" for a given situation, I would literally lock up and be unable to force myself through the situation, regardless of the amount of willpower. This could be as simple as opening up a new bank account, or as complex as getting myself a new date. (Caveat; this was not an anxiety response; but rather just... like trying to open a door when there's no light in the room and you can't feel the seams. I to this day lack the proper language to communicate the sensation.) I have never before encountered another individual with similar reactions to the world.

Perhaps it is because you are trying to do something which you do not consider an action (Is there a sequence post about this? I seem to remember reading something...). Rather than trying to "open up a new bank account" why not try to get in your car, drive to the bank, get out of your car, etc.

I often have the experience of feeling completely unable to do something but I can always break it down into concrete actions and then do those instead.

For example, sometimes I need to write a paper for school but feel it is impossible. So, instead I open a text document to begin my outline and ask myself what the first section should be about. Instead of trying to "do my paper" or "do my outline", I tried to do the steps that make up those actions.

I think this experience of feeling completely unable to do an abstract task is virtually universal for humans.

Rather than trying to "open up a new bank account" why not try to get in your car, drive to the bank, get out of your car, etc. [...] I think this experience of feeling completely unable to do an abstract task is virtually universal for humans.

What you described is a very normal response to reducing the difficulty of a task in order to reduce the anxiety response to said task to manageable levels. It is, however, unhelpful to autists who only know the global task. If you ever work with an autistic child, it would help you to be aware that such a strategy would be counter-productive. An example of what I mean is that to a profoundly autistic child, the knowledge of how to tie one's right shoe does not and cannot translate into how to tie one's left shoe. He would have to be re-taught each individual step in the process as a separate and independent task, and then he would have to be manually taught how to assemble them into both the right-shoe and the left-shoe before he might be able to begin to extrapolate from those into other situations.

It's not, you see, that I didn't know the basic steps to each of these tasks. It's not even that I couldn't conceive of ways of simplifying them. It was that I had no "algorithm" by which to assemble them into a whole. I lack the language to properly explain this difficulty to someone who has not experienced, except to say this: it is not that I was "overwhelmed". It was... like being given a road-map and shown images of every important point along the route you should take to get to the destination, and then being given a car in a disassembled state. If you don't have the tools to put the car together, no matter how well you know "how to get there", you simply lack the means to do so. Breaking down the route further isn't going to help make that happen. You have to have the ability to traverse it at all.

I am frustrated by my lack of ability to elocute this notion. I apologize for my lack of clarity and/or communicative skill.

Comment author: Incorrect 05 December 2011 03:25:41PM *  8 points [-]

I have been diagnosed with Asperger's but am very high functioning. There are definitely tasks I feel this way about; for example, sometimes I will feel completely unable to call people on the phone. Although I often have to plan my conversations in advance, I can usually accomplish such things by breaking them down into subtasks.

EDIT: Actually, on second thought I think I understand what you mean. If you asked me to "make a friend" or anything else that involved too complex a decision tree I would be unable to comply. END EDIT

It's not even that I couldn't conceive of ways of simplifying them.

So specifically what would happen if after simplifying the task of opening a bank account, you simply tried to follow the steps?

  1. Drive to the bank
  2. Walk to the back of the line
  3. Follow standard line procedure
  4. Say to the person at the counter "I would like to open a bank account" etc.

Would you be unable to come up with this list? Would you really be unable to complete the first step, driving to the bank? Would there be some interstice between steps in which you have a mental breakdown?

I realize you are saying you cannot complete the task as a whole, I am asking that if you tried to complete the individual steps of that task, at precisely what point would you fail?

Comment author: Logos01 06 December 2011 02:26:55AM 1 point [-]

So specifically what would happen if after simplifying the task of opening a bank account, you simply tried to follow the steps?

I wouldn't get to step one.

Would you be unable to come up with this list?

Nah, that would be just fine. I'd done so more than once. Without the "whole" picture, it's like trying to put a jigsaw puzzle together when you can't see the whole picture and it has no apparent borders, and the pieces have all been repainted black. You know the pieces all go together. You know you have all the pieces. You just can't visualize how they all go together.

I am asking that if you tried to complete the individual steps of that task, at precisely what point would you fail?

There is an underlying assumption here that "breaking down the task" is intelligible on some level. This is why I tried to give, originally, the example of the fact that tying one's right shoe wouldn't translate to tying one's left shoe. The pieces are learned as a whole, and conceived of as a whole. Breaking it down into individual tasks just makes it more complex, not less. It's like tearing apart the jigsaw puzzle -- it has to be put back together again before you can actually see the image on the puzzle.

I have abnormally good memory in some respects. Dates, time-passed-since, and sources are hard to remember, but stories, phrases, quotes, noteworthy or unexpected events, and some portions of conversations are accessible word-for-word years later - an example would be telling an amusing story to a friend who'd been the original source of the story, and using the same words they did to describe it to me years ago, which more than a little unsettled them.

As far as I can tell I have no feeling of this kind of memory as opposed to any other; it all feels constantly available, there's no 'lookup' or 'let me think' feeling at all. Up until recently I have never had the 'tip of the tongue' phenomenon (it's either available or not and I automatically know which without question), but I've been practicing trying to remember things I think I can't, and I think I've had this feeling once or twice.

That reminds me; while I tend to remember techniques and equations easily enough, my software has a bug where people with similar occupations and similar initials are easily confused with one another, even if they look very different from one another.

I think the classic example was the time I mistook Britney Spears for Beyonce.

I don't know that I have much to say about it. It would be hard to name an aspect of vocal technique or musicianship that Beyoncé doesn't do better than Britney. Beyoncé has a naturally beautiful voice and is in near-total control of every sound that comes out of her mouth -- flawless pitch, lots of different colors and effects. She also is an excellent musician and has ideas about how to perform a given song in a way that's engaging and effective. She has what singers call good "diction," i.e. clear pronunciation of words. I wouldn't even be tempted to say any of those things about Britney.

You might enjoy reading this blog post. A classical voice teacher was given some examples of heavy metal singing to review (from the point of view of vocal technique) for a metal blog. In addition to being interesting reading, I think a lot of people appreciated the point that many of the kinds of skills needed for good singing are constant across wildly different genres.

If you wanted me to comment on something more specific, let me know.

This may be more common than you think.

I know two women who are close friends and whose first names begin with the same uncommon letter. One is white, the other is black. One was plump, the other was slender (they've converged to some extent since, but I'm talking about a while ago). One has a loud voice, and the other a soft voice.

People would confuse them with each other.

Comment author: erratio 05 December 2011 02:05:53PM 9 points [-]

If I may ask: how old are you?

I used to have the same ability (and am still well above average) but it's lessened over the past 3 years or so. I've been trying to work out whether it's due to a) age (greater number of life experiences and/or memory naturally less good), b) studies (prioritising studied material over episodic memory), c) greater socialisation (I used to be fairly isolated, so it's possible that there were just fewer noteworthy things to remember), d) some other factor.

And relatedly: do you also have that sense of frustration when people keep repeating themselves over multiple conversations? It took me a long time to realise that they weren't doing it on purpose and that not everyone can remember what they've said to who in the past.

I can live with repetition over multiple conversations, but prefer it if the person will let me mention that I've heard and remember what they said.

What drives me crazy is the extent to which most people repeat themselves in the same conversation. I may not be doing anyone a favor by pointing this out-- but if you listen, you'll find that the real world sounds rather like Waiting for Godot, though the topics are more varied.

Comment author: TheOtherDave 05 December 2011 05:07:41PM 8 points [-]

I have concluded professionally that I am far more effective when I repeat myself often in conversations: I get more evidence later that the information I was conveying actually gets across.

I have yet to decide whether it's because people mostly don't understand and/or forget what I've said, so repeating myself increases the odds of a particular message getting across, or because people understand repetition to be an indicator of importance, or for some other reason.

It frustrates me, but I try to do what works rather than what I think ought to work.

Comment author: NancyLebovitz 05 December 2011 05:32:26PM 2 points [-]

That's a good point. Do you have a way of telling whether what you're saying has registered, or do you use a heuristic that a certain number of repetitions is likely to work?

My impression is that a lot of repetition isn't strategic, it's nervousness (I think people are more likely to repeat themselves when they're looking for support and feel unsure of getting it) or making sure they get more time in the conversation.

Comment author: TheOtherDave 05 December 2011 07:50:59PM 3 points [-]

I came to the conclusion that repetition is valuable by looking at how often, after giving a presentation in which I convey certain facts, the audience subsequently follows up in ways that make it clear that they neither retained the facts nor the awareness that I'd presented those facts. When I started making a point of repeating my key points several times during a presentation, tying it back to multiple different topics and multiple different questions, the incidence of that sort of followup question dropped.

That said, I haven't done a careful study, and I could easily be misattributing the result to the wrong cause. For that matter, I could easily be perceiving a result that isn't actually there. Humans make those sorts of errors all the time.

I agree that a lot of repetition is nervousness, and that a lot of it is an attempt to grab floor-time. (I'm not sure I'd call the latter nonstrategic.)

I also think a lot of repetition is an attempt to maintain control of the attention of the group. (As in:
A: "X"
B: "Y"
C: "NOT(Y)"
A: "X."

Comment author: MixedNuts 06 December 2011 11:57:16AM 2 points [-]

If the person you're talking to is distracted by another task or has a short attention span, they may appreciate repetition, for example if the person you're talking to is distracted by another task or has a short attention span. (I have accidentally sounded like this in LW comments before.)

Currently 22. The effect was present and seemingly unaffected moving from early school (no study) to final few years of school (lots of study) to university (some study) to current day (very little study). I've always been highly social, can't rule that out.

And yes! It's not quite as frustrating for me as it is for them, because I finish their stories for them, sometimes in the words they were going to use. I'm guilty of the same thing, though - I find it hard to remember which stories come from where. It's only once the person begins the story that the rest of the story becomes available.

It can even be something as trivial as always having conceptualized the passing of years as a visual timeline, and then finding out that not everyone does so.

I visualise numbers in a strange way. All people with whom I have talked about this (there weren't many) said to visualise numbers on a line or a circle. My image, on the other hand, has many sharp turns. I have put it here. The round turns in the picture aren't visualised as such; instead when thinking about numbers lying there, the whole picture turns around to maintain orientation while keeping the curved sections straight.

Comment author: Kaj_Sotala 05 December 2011 01:41:10PM *  4 points [-]

Whoa, that's awesome.

That also made me realize that I, too, have several visualizations for numbers, all of which are perceived in slightly different ways. The visualizations for generic numbers as well as years mostly resemble sort of horizontal lines, though with many "layers", which I can't fully describe. The ones for hours in the day and months in a year are circles. Temperatures are a vertical line, with differing colors above and below 0 degrees Celsius.

The year timeline is probably the most interesting, as it has several regions: the 1990s look different from the 1980s or 2000s, but it's hard to describe exactly how. The 1980s are pretty dark in color, with the 1990s much lighter. At 2001 there's a kind of an association to images of 9/11 and the day when I heard about it. 2005-2006 has pictures of my siviilipalvelus period. Late 1930s up to 1945 have pictures of Europe and Germany, and 1945-1949 or so have pictures of Roswell/Area 51 and generic US Air Force bases. The time around 0 AD has pictures of the Mediterranean and Rome, while "the time of the dinosaurs" has pictures of the Earth from space. The future is kind of a grey fog. There are a bunch of other years with their own images as well.

There is a differing resolution in the timeline depending on how well I happen to know the period: for the 1990s and the WW2 period I can see each year separately, and they're clearly marked, while e.g. the 1950-1980 period is much more indistinct.

At various points the timeline seems to head in different directions: the 1990s are left-to-right, the 1940s are right-to-left, and 0 AD is down-to-up. I don't actually see the timeline making any sharp turns, however: the regions just gradually fade into each other.

Comment author: Cthulhoo 05 December 2011 01:52:26PM *  2 points [-]

I also have colors associated to all kind of concepts: time periods, numbers, letters, tastes, music genres, even people.

E.g., my timeline is a ladder, where early universe era is dark blue, dinosaurs time is bright green, human prehistory is brown, 0 AD is yellow/orange and medieval times are light blue. Modern to contemporary era is detailed to a finer scale, e.g. the seventies are purple, the eighties are azure, nineties are yellow and 00s are white.

However, this is a very general thing: each time I recall some concept from my mind, my inner google also returns the color associated with it.

The ones for hours in the day and months in a year are circles.

Same here. The months have colors, too:

  • January - whitish gray
  • February - bluish purple
  • March - pale green
  • April - greenish yellow
  • May - dark blue
  • June - yellowish green
  • July - yellow
  • August - russet
  • September - green
  • October - red with gold highlights (New England foliage?)
  • November - brown
  • December - grayish white

Years, according to placement in decades:

  • '01 - grayish white
  • '02 - red like dried blood
  • '03 - light green
  • '04 - purple/blue
  • '05 - black
  • '06 - different shades of brown
  • '07 - yellow
  • '08 - forest green
  • '09 - 2009 was pinkish, 1999 feels like several colors at once
  • '00 - different each time, but always very dark

Although the color matching is completely different from mine, it's interesting to know that this kind of trait is not totally uncommon. Any guess about what's originating it?

There are seasonal aspects -- the whitish grays and grayish whites of winter and the foliage red of October. And in 2009 I wore a lot of electric pink in my wardrobe. But these examples don't feel at all like robust evidence, so I guess my answer is no.

It was these essays (The Visions of Sane Persons and Visualised Numerals), linked from the number form wikipedia article.

I think the cultural differences thing was just my conjecture, because the recorded number forms (as well as my own) often had turns at twelve and then subsequently at the decades, which led me to believe that they were probably based on the cadence of counting in English (one, two, three... ten, eleven, twelve, thirteen, fourteen... nineteen, twenty, twenty-one... twenty-nine, thirty, thirty-one, etc.). Whereas a Spanish speaker might be likely to develop a number form with a turn at 15 instead of 12, and a Chinese speaker to develop one with turns just at the decades.

Comment author: ESRogs 06 December 2011 12:55:52AM *  1 point [-]

It's interesting that you put history on there. I also have a history timeline that's separate from my generic number line, but I don't think I'd seen that mentioned before in what I'd read about spatial-sequence synesthesia (see my reply to jsalvatier).

At some point I realized I had a line like this for just about any sequence of things I've ever thought of. Besides the ones you've mentioned: days of the week, months of the year, grades in school, etc.

My sequence lines are not all totally unique though. For example, on the history timeline the years within a century just follow the pattern of the numbers from 1 to 100, and for me minutes/seconds and temperatures fall on the normal number line.

Comment author: prase 06 December 2011 11:42:57AM 4 points [-]

I have lines for weekdays and months, but they are trivial (the mont sequence turns 90 degrees right in the middle of June, on 1st September, just before Christmas and on 1st January, forming a rectangle. The weekday line turns right before and after the weekend, so two weeks together make a rectangle.

My lines can also have a fractal substructure - if looking in a detail on a particular region, further turns appear, usually inherited from the general number line or another relevant line or part of it. This may not be compatible with the overall structure: for example, from greater distance the stretch from 1910 to 1920 is a straight line, but in detail, any single year has the "closed rectangle" structure, beginning and ending in the same point.

To help understanding the interplay of cultural bias and synesthesia, this is the hopefully full list of turns in my history line when looked at in detail (the probable cause for the turn - a historical event or other thing - is in parentheses)

  1. cca. 220 B.C. uncertain direction, perhaps multiple turns (Punic wars)
  2. 40 B.C. right (end of the Roman republic)
  3. 30 B.C. - 0 A.D. left 180° curved
  4. 0 A.D. or 14 A.D. right (beginning of millenium / death of Augustus; context dependent)
  5. during 1st century left curved
  6. cca. 70 A.D. uncertain, probably left - right - right (end of Claudian dynasty, destruction of Pompeii)
  7. 100 right (end of century)
  8. 110/114/120 left (generic number 20 / conquests of Traian)
  9. 130 left (generic number 30)
  10. 150 - 200 right curved (to return to previous direction?)
  11. cca. 330 uncertain (Christianity official in Rome)
  12. 476 right (fall of Rome)
  13. cca. 500 left (maintaining direction?)
  14. 6th-8th century right curved
  15. 880 left (generic number 80)
  16. 890 left (generic number 90)
  17. 900 right (generic number 100)
  18. 910 right (generic number 10)
  19. 920 left (generic number 20 / assassination of Wenceslaus I)
  20. 1000 right (end of millenium)
  21. 1300 uncertain
  22. 1310 balances the 1300 change
  23. cca. 1350 left and then curved right (battle of Crécy)
  24. 1410 right (generic number 10)
  25. 1415 45° left (execution of John Huss)
  26. 1420 45° left (generic number 20)
  27. 1420-1435 curved right (Hussite wars)

I find this amazing. I have no visualization for numbers at all. I do have weak color associations, though:
0-black
1-red
2-blue
3-yellow
4-orange
5-brown
6-green
7-silver-gray
8-teal
9-blue-gray

The associations are stronger for 1-6 than 7-9, and usually only noticeable when appearing as groups of consecutive digits, eg 34. I don't actually perceive the numbers as being those colors when I see them on a page, but they have the colors in my mental imagery.

Enjoyable shivers down the back of the spine

First I heard that it might not be universal was someone's comment here a few days ago. Not sure if it's a mental or physical difference though.

When I looked at some of the links from that page, I found it mildly weird how enjoyable some people find it, to the point of using it as a form of mood management and bemoaning the loss the of it. This leads me to believe that a) not everyone has the reaction (eg. some people on reddit thought they were being trolled), and b) it's highly varied in strength/frequency/pleasantness (eg. I have very few reliable triggers and it's not so great that I seek it out).

Huh, interesting. I have this and knew that most people didn't, but never knew anything about it.

I am genuinely shocked that this isn't a universal experience. I routinely experience this at dramatic or highly emotive points in cinema or television.

I assumed this was what people meant when they say that something "sends shivers down your spine". Although thinking about it, there's a similar but distinct and less pleasant experience (which I associate with the expression "like someone walking over your grave") that I also experience.

I've had enjoyable shivers several times, but at first I was really puzzled to see that site: why make such a big deal out of it, any more than you'd make a big deal over feeling nice after having a cup of coffee or something?

Fascinating.

I am unable to take naps or fall asleep by accident. I have to be explicitly trying to sleep, and it usually takes at least half an hour to fall asleep. This holds even when I haven't slept for over a day and I'm exhausted - I still have to give myself permission, and the process is still not fast.

Comment author: [deleted] 05 December 2011 08:18:19PM *  1 point [-]

I have basically the same thing, maybe a little less marked. Nap are pointless for me unless they last at least 90 minutes, because I'll spend the first half hour or so barely dozing. I can sometimes fall asleep more quickly, though, when extremely tired. ETA I have never fallen asleep by accident (once or twice I've noticed dozy sensations creeping up on me, but it's quite rare), and I'm an extremely light sleeper.

Comment author: Protagoras 05 December 2011 02:55:12PM 14 points [-]

I'm not sure how common or rare this is, but the visual images I recall are stunningly lacking in detail. For example, in the case of people, even with someone I know very well, it is rare for me to be able to report so much as their hair color on the basis of the mental image I call up when I try to think of them. I don't seem to have any unusual difficulty recognizing people, or any tendency to confuse my various mental images with one another, and the mental images don't seem incomplete until I start thinking about questions like how to describe them. I'm sure I would be completely useless to a police sketch artist if I were ever a witness to a crime.

Comment author: [deleted] 05 December 2011 05:21:09PM *  3 points [-]

I do this too, but only for faces. I have detailed mental images of things like buildings and circuit diagrams, but I don't have good mental pictures of people's faces. I don't have too much trouble recognizing people (though I suspect I am below-average at it), but I can't visualize or describe anyone's face when I'm not near them.

Likewise, when I'm reading fiction, I don't have clear mental pictures of what the characters' faces look like.

Comment author: NancyLebovitz 05 December 2011 05:52:10PM 2 points [-]

I have very limited ability to visualize images or to imagine/remember sounds.

The weird thing is that sometimes with fiction, I'll feel as though I know what a character looks like, even though I can't visualize it. This is strong with Tolkien (the movie hobbits were wrong, wrong, wrong), while with Bujold, I simply have no idea what the characters look like. Having a sensory experience with fiction is so rare it seems like a miracle.

At the same time, if fiction has too few sensory cues, I'm apt to feel disconnected and uninterested. This is especially notable with military science fiction-- and it may be related to my having more problems with telling people apart if they're wearing uniforms.

I've wondered if what fiction people like has something to do with brainwave similarities between the author and the readers.

I have this too, though I've moderated it some by explicitly practicing the skill. I essentially never see people's faces when visualizing what they're doing, nor when I'm dreaming.

How did you practice it?

Comment author: fiddlemath 06 December 2011 04:09:17AM 6 points [-]

I'd already learned that, to be able to remember's people's names later, I had to make an actual effort to repeat their name to myself while I was looking at them. So, I then started consciously trying to notice details about people's appearance when I first met them - what's their hair color, what color are their eyes, what are they wearing and carrying. Eventually, this effort became a habit. Now, I usually do this automatically when I first meet someone, and I remember more of those details.

As to what they're wearing and carrying, I'm practising to avoid relying on this too much now. I've gotten into trouble before by remembering people by what they're wearing when I'm introduced to them instead of by their faces. :/

Comment author: cata 05 December 2011 09:05:13PM *  6 points [-]

I don't know if this is fair, because it's not me, but a family member of mine credibly claims to have no conscious visual memory. For example, when she drives down a highway which she has driven many times before, she doesn't automatically recognize the different parts of the highway as I do, without effort; she has to remember specific facts about where things are (like, I take exit 102 to get to place X, which is after a radio tower and then a curve) and then apply those facts to know where she is. She cannot picture her house in her head; she recognizes it by remembering salient features of its exterior. In contrast, her semantic memory and general cognitive ability is exceptional.

Some tasks, like playing games or solving problems that lean on visual and spatial imagination (e.g. the IQ test problems where you fold shapes up) are very difficult for her, although some of those can also be hacked around by remembering relationships (the dot is on the side clockwise from the square, etc.) According to her, she didn't even realize that other people had this capability in a different way until she was college-age or so.

Personally, I have what I think is above-average visual and spatial imagery -- I play chess and see the pieces moving in my head, I read fiction and imagine the settings and characters, and so on. I guess it takes all sorts.

Nothing too exciting.

The easiest one is: sexually attracted to the two most popular genders. (Possibly to others as well; I don't know.)

In my twenties, I was involved in some lexical priming studies in which I seemed to be a radical outlier in terms of how long secondary meanings of words stayed activated as I processed a sentence... I was several sigmas out on the right-side tail of the results I saw. There's a pretty obvious just-so story to be told about the relationship between that and the ability to notice alternative interpretations of an utterance, which is something I'm unusually good at in my cohort.

I suffered pretty severe brain damage a few years ago and recovered from it... fully, as far as I can tell.

The last thing I can remember having the "Oh, other people do this too?" experience about was the photic sneeze reflex, which according to wikipedia is actually pretty common.

My visualization for aversions is that they emanate waves of pushiness.

I don't feel like they are pushing me away (unless they're active), but it looks like an invisible field which would push me should I try to interact with it.

Strength varies, probably with aversion strength.

I'm still figuring this out, but I think I compensate for poor mirroring ability by intuiting a person's "story," extrapolating what will be good for that person (regardless of whether they realize it or not), and then enticing/prodding/shoving them conversationally in that direction.

I have a spectacularly good sense of direction but I have to think for a second to remember right and left.

I used to have a terrible problem with intrusive thoughts -- awkward, painful memories coming unbidden -- until about ten years ago when I spent seven months nigh-friendless after moving to Portland, OR. During that time I somehow figured out how to collect the bad feeling in an imaginary ball and expel it, either with an exhalation of breath or a squinting/head-shaking or throwing gesture. It works instantly and completely. I do this somewhat frequently but I don't think anyone notices.

I can usually tell within minutes if I'm going to be close with someone for a long time. I'm almost always right, and sometimes the other party doesn't realize it or understand why I get impatient when they don't want to skip directly to greater intimacy.

I anagram most words within my visual field, mostly without noticing I'm doing so. I also half-consciously read phrases backward and acronym-ize stuff like license plates.

Trying to socialize with more than four people results in me either becoming the center of attention or checking out of the conversation completely.

I'm mostly indifferent to children and animals. I don't dislike them. I'll even occasionally pet my landlady's cat or converse with a toddler. But I don't form bonds or miss them when they're not around.

If I have a song in my head, it gets rhythmically altered and iterated until it's unrecognizable. Phrases with similar cadences and syllable counts typically fuse and loop and iterate as well.

In one psychology experiment run by an acquaintance of mine, I was asked to dip a hand into ice water for an extended period and rate my discomfort level (the experiment also included groups which were lied to as to when they'd be told to remove their hand). I rated it as 2; days after the experiment, my acquaintance said that was abnormally low discomfort.

Similarly, in the hospital as I was recovering from peritonitis, the nurse was skeptical of my 1-10 pain rating of pi.

I guess it's just that I can remember how much things really hurt when they really hurt so my 10s are much closer to the real maximum pain than most peoples'. In that case it's not really my brain, but my mind?

Comment author: Nornagest 05 December 2011 07:51:19PM 5 points [-]

I'm a little surprised that those uncalibrated pain scales enjoy such wide use; with no obvious anchors, I'd expect people's subjective responses to them to vary quite a bit. Since this doesn't seem to be the case, I suppose most people are anchoring on something I'm not.

The last time I was asked for a pain rating (doctor's visit following trauma to an eardrum), I hemmed and hawed over it for a while and finally interpreted it as a quasi-logarithmic scale with 1 being the least perceptible discomfort definable as such. This seemed to confuse the nurse.

I was talking to a paramedic, who uses a 1-10 pain scale as part of his patient assessment. He said that it's common to have a patient reply "ten" and then the paramedic would say something like "When your wife gave birth to your child, that was a ten. Are you sure this is a ten?" after which the patient decides that the pain is actually more like a five.

A friend of mine in college had a story about a dislocated elbow. The conversation was early in the diagnostic process, possibly over the phone:

Friend: "I have a dislocated elbow."
Nurse: "On a scale of one to ten what's your pain?"
Friend: "Seven."
Nurse: "Then you don't have a dislocated elbow. Those are very painful and people say ten when it happens."
Friend: "Kidney stones are a nine. I'm saving ten for something worse than that."
Nurse: "Oh... [stops to think] Then I guess you probably do have a dislocated elbow."

My answer at one point (when I was in a rehab center recovering from a stroke) was something like "if 10 is, say, having a burning building collapse around me, this is a 3. Maybe a 2. I'm not sure... I've never had a burning building collapse around me, but I'd expect it sucks."

Eventually I calibrated my answers against the pain meds they were giving me and just started giving them numbers.

Comment author: Prismattic 07 December 2011 02:13:04AM *  9 points [-]

Based on this, I assumed the pain scale was something like

0 = I was unaware that receiving oral sex is part of the evaluation process, but thank you, nurse.
2 = The mild irritation of needing but being unable to sneeze.
4 = This is actually just ennui.
6 = The stupidity of your diagnosis would cause me to facepalm if my hands were not so badly burned at the moment.
8 = I've recently been smashed in the face with a cast-iron frying pan. How do you think I feel?...
10 = ...and now my eyes are leaking pimples on to my face as well. Dammit!

One of my hunches is that people differ much more than commonly thought on the accuracy and strength of face recognition, even outside of clinical prosopagnosia.

I'm very poor at this, tending both to not recognize people, but also to over-recognize; some days every stranger I cross makes me think of someone I know strongly enough that I almost break into a smile and start greeting them, and because of past embarrassing occasions I've developed compensations which now manifest as shyness.

I'm very bad at recognizing celebrities; I've often been out walking with my wife or with friends, and hear "Oh look, here goes X" where X is someone I saw too much of on TV. And I've totally missed them going by, and a second glance leaves me unconvinced it's actually X.

The kicker though, for me at least, is this: how many social conventions are built around an idea of how people commonly think - which in many cases is largely wrong?

For instance, using name tags at a social gathering will earn you my everlasting gratitude, especially if they would not normally be expected. So will encouraging people to look at them, and designing so that they remain visible at all times (large type helps).

There is a special spot reserved midway between Heaven and Hell (actually not, but you get the idea) for people who have the bright idea of providing name tags, then screw it up by printing them only on one side and putting them on lanyards where (in accordance with Murphy's Law) they systematically end up chestwards.

Our badges at work are like this[1], and unfortunately, it has implications beyond not remembering names -- that makes it easy for an unauthorized person to go through the facility unchallenged by having the (uninformative, easily-faked) back side of the badge showing.

This is what I was going to post about. I am terrible at recognising faces. People I know well are fine, but even a quite good acquaintance in the wrong context can easily throw me completely. There are a very small handful of celebrities I can recognise by their faces. I recognise most people below the level of fairly-good-acquaintance by their voice, not their face. There have been many occasions on which I haven't realised I know someone, or have seen an actor in something else, till they speak.

It's also not quite that I remember the features but can't synthesise them into a face, which I think some people with this difficulty find -- I have real trouble remembering features, too. Half the time, if you ask me whether friend-so-and-so has dark or light hair, or is tall or short, I'll struggle to say for sure.

I think I'm relatively bad at reading facial expressions, too.

I'm fascinated by kinesthesia. I've put in some 30 years getting moved into my body. It would probably be more exact to say that I'm improving the connection between my conscious mind and my kinesthetic information, but "getting moved in" is how I think about it.

I think of myself as having a very good associative memory-- you talk about something, and there's a reasonable chance I can remember a magazine article I read 20 years ago that's related to it. However, when I've mentioned this, a fair number of people say they have it too.

My ear-mouth coordination is poor-- I'm bad at singing or imitating sounds.

I'm good at summarizing.

I'm fascinated by the inside of my head (details of how my experience works). Sometimes this pays off-- I discovered recently that some attention and movement problems were the result of my believing that I didn't to things fast enough, so I'd try to do them faster than I could get the sensory information I needed.

Psychetypes by Michael Malone is a rather theory based look at the Myers-Briggs personality types, with emphasis on how they perceive time and space. The general theme is that there are many ways of thinking and acting which add up to normal-to-excellent functioning, and they're more different from each other than you could imagine if you only look at your own experience.

While I'm not convinced that the Enneagram is a complete theory of personality, it's another good angle for looking at mental variation. The hypothesis is that everyone makes primary use of one of nine filters, though the others can come into play. I will say it explained some things to me when I realized I'm apt to use the search for perfection as a general way of looking at things.

I think the most different part in my mind is how I value sensory inputs very lowly compared to most people. I do enjoy (some) food, but I don't care much about it as long as it's not something I really dislike. I prefer games which are more abstract (like pen&paper role-playing games) over more graphically shiny games. I do enjoy sex, but much less than other people seem to enjoy it, and I would definitely not do much efforts just for sex (relationship is a different issue, but it's not the sex I value in it). I prefer, by far, to read books rather than to watch TV. I value much more "internal" things (feelings, ideas, planning, knowing, understanding, ...) than I value "external" things.

My other difference is that I tend to not visualize spatially things well (I prefer text over schema, I'm easily lost in a city, ...), but that comes from a birth defect that made me unable to see in 3d until I got a surgery at the age of 2.

I have a weirdly good memory for things I hear said in conversation.

More interestingly, it took me many years to understand that I did not experience hunger in the same way as other people. I feel no physical sensations associated with it (nothing like a "hollow" feeling in the stomach, or rumblings, which are apparently more common symptoms). When I haven't eaten, I just find that my thoughts just keep turning towards food items. I have recurring thoughts of fruit, or something like that. When I was a kid, my parents didn't understand the way I was eating. I would never get seconds at meals. I would just eat whatever was on my plate originally, even if it was tiny, and then get up. A couple of hours later, I would be getting an apple from the refrigerator.

I remember learning what hunger feels like; I was probably around 8 years old. It's not that I hadn't had those sensations before. I just hadn't consciously made the connection between the sensations and the amount of time since my last meal, thoughts of food, etc.

Incidentally, more recently I've refined my hunger-related sensations. In particular, when I'm under stress I often tense my abdominal muscles which can lead to[1] sensations that are similar to hunger pangs, with predictable results. Intentionally relaxing those muscles and paying closer attention lets me discern which sensations are due to hunger (low blood sugar or empty stomach) and which are due to stress.

[1] Though actually, I'm not sure if that's the correct causality.

I don't get hungry either. Every four hours, I start feeling weak and irritable and concentration becomes difficult or tunnel-vision-y. If I don't eat, those feelings go away after about an hour.

I remember having normal hunger feelings until I was maybe 14. I'm not sure, but my increased skipping of family mealtimes might've knocked my system out of whack.

When I think about things, in addition to mental images and internal monlogue, I have very vivid tactile and kinesthetic sensations. For example, if you were to say "high-heeled shoes," I would only dimly picture a pair of heels, but I would immediately imagine how they would feel in my hand, how it would make the arch of my foot feel to wear them, and the emphatic stamping sensation of walking in them. It's the same even with abstract ideas; negative numbers feel a particular way in the pit of my stomach, and factoring feels like a physical process of disassembly.

I've previously discussed "the beat" on here. Varying degrees of musicality seems to be a pretty pervasive theme in other comments and similar discussions.

Ooh. Here's one. I seem to have a faculty for formulating highly inappropriate or subversive responses to things. When asked "what's the most inappropriate personalised message to put on an easter egg?" I immediately come up with "lots of tiny swastikas spelling out 'fuck the police'". This is useful for comedic, literary and poetic purposes, and I can generally recognise other people who have the same faculty if I talk to them for a little while or appraise their work in any detail.

Staying on the subject of poetry, I also have an utterly fastidious and unrelenting need for perfect scansion in poetic verse. When I read or listen to the work of a poet or songwriter, I can generally tell if they have that same need. Over 160 years after his death, for example, I can tell that Edgar Allan Poe was driven to distraction by stray metric feet in the same way I am. If he wasn't, his work wouldn't be the way it is.

When asked "what's the most inappropriate personalised message to put on an easter egg?" I immediately come up with "lots of tiny swastikas spelling out 'fuck the police'".

I don't understand. What's particularly special about that, that it counts as the most inappropriate personalized message? Why is it worse than, say, lots of tiny heroin needles spelling out "Your Child's Leukemia Is Hilarious!"

Comment author: sixes_and_sevens 06 December 2011 12:19:52AM *  9 points [-]

I wouldn't claim the ability to produce the most inappropriate such message; simply a highly inappropriate one in response to that question, immediately and reflexively, whether I wanted to or not.

It is, however, superior to your suggestion for a number of reasons:

1) It's considerably more achievable to spell out a three simple-word message with no punctuation in recognisable swastikas on an easter egg than it is to spell out a five complex-word message with punctuation in recognisable heroin needles in the same medium.

2) Swastikas are an immediately recognisable and highly historically, socially and politically charged symbol in a way that needles simply are not. You'd have a hard time even getting people to recognise a pointy blob piped onto a piece of confectionery as a hypodermic needle, let alone conveying the idea that it was for the purpose of injecting heroin.

3) "Fuck the police" is also an existing politicised statement, primarily associated with black gangsta rap group N.W.A., but also a broad anarchist sentiment taken in isolation, while "Your Child's Leukemia Is Hilarious!" is simply a highly distasteful fabricated statement without any precedent impact. It makes people go "ew", unless they actually have a child with leukemia, in which case it's just grievously cruel.

4) It's composed of radically opposed concepts, instead of randomly disjoint ones. Swastikas and gangsta rap lyrics emphatically do not belong together. More generally, anarchist and fascist statements aren't the most cosy of bedfellows. Heroin needles and leukemia hilarity are just randomly thrown together. Mine is subversive in structure, whereas yours is just surreal.

5) It's generally punchier. People can interpret the components immediately, and then their brains encounter resistance as they try to put them together. You get a sudden "WTF!?" moment since it's easy to read but hard to understand. With the heroin needle leukemia hilarity suggestion, the reader is presented with two quite hard-to-interpret elements, so the confusion happens at the wrong point. It's hard to read, but easy to understand, and the payload isn't worth the cost of delivery. It's like a shaggy dog story as opposed to a snappy one-liner.

6) When someone says "Your Child's Leukemia Is Hilarious!" they're clearly just going for the most shocking and distateful ideas that they can think of, since very few people think terminal childhood illness is genuinely funny. Once you realise that, you dismiss it as kind of childish. But people do use swastikas as symbols of their allegiance to horrific ideals, and people do say "fuck the police" and mean it, because they have legitimate and complex issues with authority figures and social institutions. Taken independently they could be serious statements. Only in combination do they become a jokingly obtuse, clearly over-the-top gesture of intentional offensiveness.

Back to the broader point, I believe people with the faculty I am claiming to possess would instantly and intuitively find mine more entertaining than yours, because they will likey favour inappropriate humour.

I probably share your sense of humor. But just two nitpicks:

It's composed of radically opposed concepts, instead of randomly disjoint ones.

Since the neo-Nazi activities are often illegal, the Nazis may quite easily say "fuck the police". I am not too familiar with the Nazi subculture, but (therefore?) I would be able to mistake the combination for a genuine expression of political opinion (not sure about that if they happened to be painted on an easter egg).

I believe people with the faculty I am claiming to possess would instantly and intuitively find mine more entertaining than yours

This sounds tautologically trivial, unless the faculty is defined more precisely than it was.

Comment author: sixes_and_sevens 06 December 2011 04:13:28PM 1 point [-]

I've met (way) more than my fair share of anarcho-communists. They're real, fairly intelligent and reasonably well educated people who simultaneously hold what I believe to be radically opposed and mutually conflicting philosophies. The fact they exist doesn't make those philosophies any less radically opposed or mutually conflicting. It does make them kind of funny, though.

As regards the tautology claim, I'm not saying people who share my sense of humour will prefer things I also find funny. I'm saying that my sense of humour is informed by my tendency to spontaneously formulate inappropriate responses to situations. Impropriety is in many ways an aesthetic property, and other people with that tendency to formulate inappropriate responses to situations will have an aesthetic appreciation for it when they see it carried out by other people.

Comment author: prase 06 December 2011 04:51:59PM *  2 points [-]

I wasn't meaning that existence of Nazis fucking the police implies absence of contradiction in that action, but rather that "fuck the police" and swastika aren't necessarily immediately perceived as symbols of opposed ideologies. I know what a swastika symbolises, but as for "fuck the police", my internal ideology analyser returned a rather generic "political contrarian" label, under which Nazis can be classified without difficulty. Needless to say, I have no knowledge of gangsta rap.

(In a sense, putting two contradictory ideologies together makes them somewhat cancel each other and makes the whole thing less inappropriate. Combining two compatible symbols would have a stronger effect, as long as inappropriateness is the main goal.)

Comment author: sixes_and_sevens 06 December 2011 06:06:13PM 2 points [-]

I think a distinction needs to be drawn between "inappropriate" and "shocking". Shock is about the magnitude of anticipated response, whereas impropriety is about things being out of place. They can go hand in hand (the most inappropriate things usually have a shocking aspect), but they don't quite work in the same way.

If you want to maximise shock, you transgress the biggest taboos you have available, but if you transgress too many at once it stops being shocking and starts being farcical. If you want to maximise impropriety, you need to provide something tailor-made to transgress the specific taboos of the situation you're in. By way of example, if a gynecologist wolf-whistles while giving a patient a pelvic exam, that's inappropriate. If he stabs her to death, that's shocking. If he chops her up into bits and feeds her to orphans working in his sweatshop that manufactures clubs for killing baby seals, that's farcical.

The contradictory nature of "fuck the police" in swastikas is somewhat farcical, making it irreverant about serious issues in a way that isn't as bluntly shocking. This is probably the "cancelling out" you mention. It could certainly be more shocking, but it's supposed to be out of place, not to generate a response of high magnitude.

I used to go around saying, "I am the only person I know of who does not believe he is unique."

(Always loved deliberate irony like that.)

It's true, though. I do not believe it likely, or even statistically possible, that I have thought any thoughts not thought by someone else, and this seems to be an uncommon (but not unique) thought.

I've also been obsessed with meta, and I thought this was uncommon as well until I started reading Hofstadter.

A few things:

1) I seem to have a much better long-term memory than short-term memory. I always seem to be able to remember details of events long ago based on just small reminders. Yet in daily life I always find myself having to ask people to repeat an explanation or list becuase it just "vanishes" from my mind shortly after I hear it. I'm always having to stop and write stuff like that down.

2) I automatically try to "plug in" everything I learn into the rest of my understanding: see how it relates to other topics, what inconsistencies there might be, etc. This makes it easier for my to pass on understanding to others, as I just follow back the "inferential path" in my mind and then trace it out in the person I'm explaining it to.

It's led to frustration in that I've long assumed everyone else represents knowledge this way, so when they give bad explanations, it's because they're not even trying, but typically, it turns out they haven't connected the subject matter as deeply in their own mental representations. (Yes, I've talked about this before, didn't dig up the links.)

3) Whenever given some objective or criteria, I immediately think of how to fail it in the worst way possible. For example, if I'm told not to mention Bob's balding hair to him, I immediately think of the most horrible way to do so. (Naturally, I don't act on these ideas, but my mind sort of defaults to thinking about them to fill the empty space.)

Thanks for doing this, I've been wanting to gather this information as well, perhaps later come up with a standard checklist so people can find out what kinds of mentalities they have are abnormal.

Comment author: Antisuji 06 December 2011 12:11:40AM 3 points [-]

I have a tendency that's possibly related to your #3: when someone makes a factual assertion I immediately consider its negation as a distinct possibility. That is, the negation becomes more available to me, and therefore in some sense more plausible. Else, why make the assertion in the first place?

Comment author: Normal_Anomaly 05 December 2011 10:14:01PM 2 points [-]

When I'm deep in thought, I will sometimes have a short, convulsive shiver for no particular reason. It's strong enough to be visible to people nearby, and unnerving to some of them. I don't know if that counts as my mind, but it is weird.

I am very interested in my dreams, and make a point of remembering interesting facts about them whenever possible. I have vivid dreams with a wider range of sensations than anyone else I know, including: color, sound, texture, proprioception, sense of falling, the sensation of having something disgusting touching me (does anyone else get that as a distinct sensation?), realistic vomiting, occasional lucid dreams, and occasional metacognition during non-lucid dreaming. I don't have all of those in any given dream, but I have experienced most of them in the past year and all at least once.

When I have falling dreams, I (sometimes?) jackknife my actual body into the air such that it hits the mattress when my dream body lands and I wake up. I know this because I once woke up on purpose in the middle of falling and caught myself doing it.

A few relatively unusual things that come to mind:

People often make claims that even atheists have "God-shaped holes" that they need to fill. I have never felt this way, and I have no visceral understanding of what others mean when they say that they do feel such a thing. This also applies to related concepts, e.g. a search for "universal meaning," a religion-inspiring feeling that "there must be something greater out there," etc.

I'm somewhere in the middle of the introversion-extroversion scale. I enjoy socializing, but I still need time to myself in order to recharge mentally. Extroverts tend to see me as "one of them" at first, and then they become confused when I don't always want to go out and party.

I never went through the (seemingly typical) stage in childhood where one has a general dislike of/aversion to the other gender. I was friends with both boys and girls, more or less equally, since preschool if not earlier. (I myself am a straight male, to contextualize this for those curious.)

There was an interesting survey several years ago on Cosmic Variance about our mental images of time. I'll quote my response:

My main physical conceptions of time are in terms of years or weeks. Both involve spirals, although oriented differently.

For years, I think of them as a clockwise spiral going upwards, such that any two years make a complete circle when seen from “above.” For example, if I picture this year and then next year, it’s a circle where the bottom is January 2009, the left middle is Summer 2009, the top is Winter 2009-2010, the right middle is Summer 2010, etc. There’s definite seasonal imagery connected to this view. To try to demonstrate this, a diagram is -(:)-, where the -’s are summers and the .’s are winters. I often picture myself as being “on” a certain part of the spiral/circle, e.g. right now I’m coming up to the “top” of the 2009-2010 circle.

For weeks, I think of them as a spiral going to the right, so that if you look at it from the side, “days” are in the front and “nights” are in the back. I picture a week like this: |S|M|T|W|R|F|S| (often without the days labeled, but I put that there for clarity), where each day goes off to night and then loops around behind to connect to the next day in the morning.

I imagine any other timescale as just a long line going left to right.

There seems to be quite a range of mental images of time among people.

From the other side of the spectrum: I pray to a god I know doesn't exist, just because I feel a compulsion. Many atheists do not understand what the need to worship feels like. It's not about being scared of life and wanting a sky-daddy to comfort you. It's not about trying to outsource critical thinking. For some people, worshiping a god is just something you've got to do. Like taking a stretch after being cramped in an airplane.

I experience numbers as being on a line that runs left to right, swerves to the left at some number, continues upwards, and then returns to running from left to right. My experience of temperatures, people's ages, and the days of months is similar, but with different patterns of where the turns are. However, I think it may actually go right to left somewhere in the millions, though I'm not sure. Negative numbers run to the left forever, as far as I can tell. Calendar years are slightly different, in that they take more rounded turns and seem to be capable of going in any direction. The months of the year are very different. They make a letter "D" curve with January at the top and December at the bottom, but the link between January and December seems to be "pinched" rather than connected by a straight line. Also, the days of the week have different shades, Monday-Friday are all slightly grayish, while Saturday and Sunday are bright.

I also experience the letters of the alphabet, numerals, punctuation marks, months, days of the week, and various mathematical symbols as having genders and personalities.

I seem to be unable to think without internal monologue and visualization both being active. Whenever I imagine something, my internal monologue is describing it, and whenever I think verbally I visualize what I'm "talking" about.

I have an exceptional memory for auditory information.

I am usually almost completely indifferent to adult suffering.

I can get lost in deep thought such that I may forget where I am or the time of day or what I'm doing, etc. In these episodes, it may be quite difficult to get my attention.

I can hardly look at an object or person without them having a strong influence on my line of thought.

I conceptualize manipulations of mathematical expressions as movements consisting of slides and "flips".

I often have familiar music playing in my head. I know it continues to play even when I'm not aware of it, because of the following evidence: Sometimes I observe playback of song S1, followed by a period of not being aware of any music, then observing playback of the unrelated song S2. And in hindsight, there is a point in S1 that is a natural segue into S2.

I'm sometimes unaware of my emotions. I didn't know this was possible until kinda recently.

I'm most comfortable with non-verbal thinking. When I think verbally I'm more rational (as opposed to intuitive), but am slower and tend to get lost in tangents. For this reason I used to regard the Sapir-Whorf hypothesis as obviously false. Now I consider it to be a confused question.

I experience ASMR only when a barber uses electric clippers on the back of my neck.

I get butterflies in my stomach when I'm in love and/or on rollercoasters. This is a physical sensation.

One that I realized quite quickly, I have an uncomfortably strong level of empathy. Or more accurately, a strong discomfort towards emotional disharmony in others. The strongest is in strong arguments or social awkwardness. I can barely stand to watch those intentionally awkward scenes in sitcoms and movies.

I have a preternatural ability to see what others are trying to say. This comes out in two ways. One, if someone is talking to me, and they make an error, my brain will autotranslate. So if they said brother and meant father, I will hear what they meant. Sometimes I don't notice this translation until they point out an error they made. And then I'll be able to recall specifically what they said. The other way it comes out is I can spot miscommunication very easily. If two people are having a "who's on first" moment, I'll see exactly where the confusion is, and what needs to be said to fix it. It's awesome and weird.

Both of the previous items cause me to have a natural urge to resolve any conflict going on, trying to act as mediator.

Like some here, I think I have mild number synethesia. Mental math sometimes has a visual component, with numbers splitting and merging. Additionally, numbers...um....look a certain way. So the number 15 looks really 3-ish and really 5-ish. It's also a very sturdy, compact number (because it fits into 60 so well.) The lower numbers also have an aesthetic, usually based on how divisible they are or how common a divisor they are. So, 2,3,4,12,60 are all pretty but 31 or 57 are ugly. Higher numbers blur a bit for me. This may be a heuristic for how easily my mind manipulates those numbers.

Also, and with the main population I feel like an oddity for this, I derive significant pleasure from completing math problems. I imagine many others here do too.

I also had an uncomfortably strong level of empathy specifically towards people doing something that would make me uncomfortable, in a social sense. When I watched someone talking and embarrassing themselves in class for example, it felt like my insides were trying to escape my skin.

This actually went away after watching all of the seasons of The Office (the American version).

However, I'm pretty sure I feel an abnormally low amount of empathy for other emotional states in other people (both positive and negative, this was unaffected by watching The Office)

I would say that I'm completely and utterly neuro-typical. I don't have anything interesting to talk about. I don't visualize months as colors, my memory doesn't seem remarkable in any respect, my visual and bodily sensations aren't particularly dull or vivid, etc.

I have experienced some pretty extreme social anxiety many times in my life, but it always totally vanishes when I spend any length of time interacting with people (e.g., because a job requires me to). In fact, I tend to have this sort of attitude about most things. It's not really a matter of being fundamentally neurologically atypical; it's probably just something atypical about your lifestyle that makes you like that.

Is this guy physically atypical? Yeah of course. Most people aren't that strong or agile. It's pretty rare to walk past somebody who's at that level. But does that mean that he's fundamentally any different than most people? Probably not. He's no more remarkable than a dude who's super obese. They have different lifestyles, and it results in different looks and abilities.

I don't want to over-generalize my own experience, but I think there's plenty of truth in what I'm saying. I think there's way too much of an emphasis on being born all special and unique, and way too little on just how much control you have over your mental and physical abilities. I'm perhaps an astonishingly boring case when it comes to these kinds of threads, but it may well be because I wouldn't let an arbitrary mental abnormality stand longer than the duration in which I fail to introspect it.

I think there's a way over-emphasis on and exaggeration of mental oddities in communities like this, and I think it's for a very basic reason of social signaling. In a lot of ways, they function as backhanded compliments. Usually they come in packages of great disadvantages but also epic benefits. High-functioning autism comes to mind, where they claim to have various problems (social etc), but then also have a few super-powers. It's socially easier to sell your identity as a bundle of strengths and weaknesses than it is to stroll around claiming to be 100% awesome.

I don't really know anything about autism or Aspergers or anything, and I certainly don't want to insult anybody who really was born fundamentally neurologically atypical, but I think there's a huge social pitfall in communities like this, where people throw around labels like that way too recklessly. I've read countless posts on here that sounded as if they were bragging about their HF autism or even about how the LW community seems to have an abnormally high saturation of this neurological oddity.

It may be important to note that a lot of psychology seems to have a destructive, politically correct outlook on personality types etc. For example, the Myer-Briggs whatever seems to go out of its way to emphasize that no personality type is "better" than any other, and that they're all just different. Each of them has their advantages and disadvantages, just like a ton of the comments in this thread and others seem to imply.

Well I have a different outlook. I'm striving to be an unmitigated success in everything I care about. I don't want to have advantages and disadvantages; I want only the former. And I think it's possible, or at least much more possible than most people seem to act.

In summary, I think a lot of what passes as "neuro-atypical" is simply the result of various lifestyle factors. I see no reason why you can't simply change from being a visual thinker to a verbal one or whatever. Most discussions seem to make it seem like you just get to announce what kind of thinker you are or what your personality type is (introverted or whatever); way too little seem to discuss which personality types or mental oddities are good, which are bad, and how to switch between them.

Less Wrong perhaps does a lot better of a job on this than most, but still not very good.

By way of disclaimer, I'm neurotypical, bar a childhood ADHD diagnosis that I'm quite skeptical about.

In any case, I agree that it's pretty common for Internet communities to place an unusual and perhaps undue emphasis on neurodiversity, possibly because of the subculture's generally high Openness (although other reasonable hypotheses exist); I did time on TV Tropes for a while, for example, and in its later years it got to be about as dismal a hive of self-congratulation as I could describe. I've heard the superpower analogy too, and I don't find it a whole lot more convincing than you seem to.

I don't think this is a signaling phenomenon, though, at least not primarily: a diagnosis carries certain sick-role implications that might be useful from a signaling perspective, and it might also further a desire to be seen as unique in some subcultures, but neither one seems to match the actual behavior involved. I think the explanation's simpler: a lot of bits have been spilled on how the Internet fosters self-reinforcing identity groups, and I think it'd be naive to suppose that this tendency doesn't extend to identity categories based on some kernel of neurodiversity. The broader culture's also gotten a lot more welcoming of small identity groups in recent decades; this might be what you're getting at with your mention of political correctness, although I'd definitely hesitate to use that term. And none of this is fundamentally a bad thing. It can lead to bad things, if it fosters fixation of destructive traits that might otherwise wash themselves out of the memetic ecosystem, but I don't think that's worth complaining about here; LW's always been fairly welcoming of self-improvement as an objective.

The rest comes down to a nature-versus-nurture debate, and this isn't really the place; but this thread, I'd say, is fairly harmless. It's not hugely useful from a theoretical perspective, being self-sampled, and in any case I don't really expect to find any unusual neurological correlates of rationality, but if an anecdote or two ends up being interesting or inspirational from a cognitive-science point of view I'd count it as a net positive.

I sometimes (every few weeks) hear a pretty loud, high pitched sound. It eventually (within a minute) fades. No idea if that is normal or not, but it just occurred to me that it might not be.

I read at about 1100 WPM. I had no idea that people sounded out words in their heads until about two years ago, when I was speed reading an article about speed reading and realized I was speed reading. I am curious how much faster it is possible to go? Can anyone here go significantly faster? I want to know if it's worth training further.

My memory of faces might be weird. The more familiar I am with a person, the less I can visualize what their face looks like. But, I CAN visually recall (pretty accurately) pictures of those same people. For example, I have no idea what my mom's face looks like if I think of it in the abstract, but I have a screenshot that I took while we were talking on skype a few weeks ago, and I can visualize that quite well, including the glasses she was wearing, her hair, and the quality of the webcam image.

I have VERY few memories of my life before I was 11. Probably 30. And no memories of my time before I was 6. Consequently I am quite interested in life logging :)

Once I passed out while I was getting a small amount of blood drawn. When I woke up, it felt like literally ten thousand years had passed. I still feel as if there was a gap there (This is not related to the above however, I've always had about the same small number of memories of childhood). That happened when I was about 17, I am 27 now.

The older I get, the slower time seems to go. I think this is partly environmental and NOT mental in that it also corresponds to less structure (the older I've gotten, the less structured my life has become to the point where now I am completely self-directed all day every day)

Sounds like tinnitus. (I have this, but less often than you, and I wouldn't describe it as loud. A friend of mine has it constantly since he went to a loud rock concert as a boy.)

I have VERY few memories of my life before I was 11.

Wow.

When I was 8 or so I thought it was strange that I didn't have any memories from before I was about 4. Based on that, my interest in science and space travel, and my general weirdness, I decided that I was probably a space alien changeling. (Note: I no longer think this.)

I talked to a person a few months ago who mentioned that her reading speed decreased noticeably from its very high starting point when she took speed reading lessons. It's only one data point, but it may be worth keeping in mind if you're thinking of training your ability.

How meaningful is it to assign a single number to your reading speed anyway? I would estimate that mine varies by at least a factor of ten or so depending on what I'm reading (I might top 1100 WPM at the high end, but only for very basic text.)

I experienced a visceral feeling of terror when reading this. I wasn't aware that just training could hurt innate skills (I assumed it required some sort of crushing corporate environment).

Comment author: thejash 06 December 2011 02:39:43PM 0 points [-]

It's not that meaningful to assign a single number, true. I gave my speed for "normal" text--comments, blogs, newspaper articles, "light" books (business/best-sellers), fiction (if I have to/feel like reading it quickly). When I read scientific papers, the speed drops considerably until I am used to the terms used in the field.

Thanks a lot for that comment though, I have less incentive to try training it further now... I am pretty surprised that anything could decrease significantly from trying to train it though. I would suspect other effects at work (like now she is reading a different kind of text, or had previously never measured herself, or the training was nonsense, etc). Any idea what caused the decrease?

Comment author: Desrtopa 06 December 2011 02:46:51PM 0 points [-]

I can only speculate, but I would guess that the techniques she was taught in the speed reading class were less efficient than whatever she was already doing without thinking about it, so she regressed towards the average speed for a person with speed reading training, which was lower than where she started. She said that her reading speed decreased noticeably while reading similar text in similar situations, although of course it's possible that she was experiencing selective perception.

I have an incredibly poor memory regarding spatial relations. I still have to look where the night stand is by my bed is to avoid hitting it, and it's been there for more than a year now. I get lost constantly, I can memorize routes from point A to point B, but I can't extrapolate routes between points based on location, because I have no general idea of location outside of specific routes and landmarks. Given that my verbal and visual memory are superb, and that I can absorb relatively large amounts of information in short amounts of time for most things, my inability to get anywhere without a GPS or absurdly specific directions is met with disbelief and amazement on the part of those who know me. I experience very strong sensations when reading, not just visual but the other senses as well, but I imagine that's not too uncommon.

Comment author: Crux 07 December 2011 02:57:59AM *  0 points [-]

This seems like a pretty good example of what I was talking about in my reply to the OP. You gave a significant disadvantage, but then a great advantage to even it out. As always, it's socially easier to sell an identity that's a well-balanced bundle of strengths and weaknesses than it is to go around claiming to be 100% awesome.

It may also be important to point out that with each pair, the drawback tends to be more mundane (clumsy, bad at socializing, etc.), and the benefit is usually something much more "majestic" (can't think of a good word for this, but it's usually something that has less to do with our "material" existence and more to do with philosophizing, thinking, and so on).

For the utility function of the speaker or his intended audience, the drawback tends to be much less damaging than the benefit is helpful (e.g., "who cares about my athletic ability? we live in a world dominated by intellectuals!"), but for the purpose of signaling, the pairs tend to sound as if they are related enough to balance each other out. In your comment, the disadvantage was "incredibly poor memory regarding spatial relations", and the advantage was "my verbal and visual memory are superb".

They sound like they balance each other out, but of course the point is that the former is a much more "base" incompetence, and the second is what's much more useful in this day and age--one dominated not by strong, sturdy hunter-gatherers or traditional farmers, but by physically clumsy academics and scientists.

To cut this short, I should close by saying that the test for whether or not you're engaged in destructive social signaling is simple: Are you disturbed by your "incredibly poor memory regarding spatial relations", or have you simply welcomed it as a part of your identity? Has your awareness of this fact impelled you to try to fix it, or have you let it linger uncontested?

For reference, if I personally had that problem, I would be reacting something like this: "WTF IS GOING ON?? I MUST FIX THIS." Or at the very least, I certainly wouldn't accept it as a fun aspect of my identity.

I frequently experience emotions as physical sensations. I can even physically locate them in my body sometimes. For example, I feel tend to feel sadness and sleepiness in my eyes and anger in my forehead. Sometimes I end up unable to figure out what emotion my current sensations correspond to. On a possibly related note, if I pay attention to what any given part of my body is feeling, after a while I start to feel some low-level pain in that spot. I try not to pay attention to my body very much as a result.

I get lost in books and such very easily, ending up almost totally oblivious to the world around me. I also read very quickly. And if I'm not keeping my brain occupied by something, I tend to either fall asleep or get very frustrated. It also causes me to be unaware of any pains or discomforts I'm feeling.

I often have trouble paying attention to what people are saying when they are talking to me and need to ask them to repeat what they are saying; my brain seems to interpret people's voices as background noise and I have trouble turning this off.

I often have a song of some kind playing in my head. I can play melodies by ear on the piano, but not harmonies, and I usually find that when I try to recall a memorized song I can only "hear" the singer and not any of the accompanying instruments.

Whenever I am in the process of inserting an earplug inside my right ear, it presses on a spot that causes me to feel an urge to cough. It happens every single time, and it doesn't have to be an earplug pressing the spot; an otoscope can also trigger the sensation.

I don't like the taste of most chocolate. I particularly dislike chocolate milk, chocolate ice cream, and chocolate cake.

It happens to me too, but in my case I know what caused it. I had shingles in 2000 and have several facial scars and one small bump of scar tissue in my ear canal. The neuralgia associated with the scars has mostly faded, but it is fading more slowly on the scar in my ear, direct contact on the scar still triggers it and in that case gives me an urge to cough.

I frequently experience emotions as physical sensations. I can even physically locate them in my body sometimes. For example, I feel tend to feel sadness and sleepiness in my eyes and anger in my forehead.

I get this too, and in fact have long speculated it to be the way that most people probably experience emotions. For example, I feel fear as a ripple through my chest with two distinct parameters. The larger the waves and the more they travel outward from the epicenter, the greater the perceived danger. And the further to the right or left of my chest the center of the splash, the more likely the alleged danger is coming from that side.

I have introspected plenty more where that came from, and have gotten confirmation from plenty of different people that their subjective experience of emotions is similar. This isn't common knowledge, but I assume that's only because of the difficulty of introspecting such fundamental mental facts. Most people have had this sort of mental phenomena on auto-ignore since they were in their single digits, so it's usually quite hard to dig up.

There must be a subjective experience constituting each emotion (or they wouldn't exist), and it generally seems to be a combination between (1) a comfortable or uncomfortable bodily sensation and (2) various other things that would take a while to explain.

I experience ASMR, but it's only ever been triggered by listening to, or rarely by thinking about, certain songs. None of the ASMR inducing videos people put on Youtube worked for me even remotely. I do feel a somewhat pleasant numb feeling in my throat sometimes though, which seems to get triggered by the same things that trigger most people's ASMR, like soft voices. Never heard of anyone else who experiences that one.

I also sometimes can feel a weird feeling on the bottom of my foot if I rub the bottom of the opposite foot against a hard surface, like the corner of my subwoofer.

Sometimes I have a visual experience that is very hard to describe. It happens when a person is talking to me and I've been looking at them without interruption for several minutes. (Maybe they need to be looking at me too; I can't remember.)

What happens is that the person starts to seem very close to me and very small, as though I had my face pressed up to the window of a dollhouse and they were inside it. This is not exactly what it is like, but it's the closest I can come to putting it into words.

If I look away, the effect stops, but it easily starts again when I look back at the person. I can't make it happen at will, but once it starts I can turn it on and off to a limited extent.

I first noticed this when I was 13 or so.

(I don't think this is quite the type of thing Kaj is most interested in, but it's the only peculiarity of my mind that hasn't already been mentioned in other responses to this post. Indeed, I've never heard of it anywhere, so if anyone has, please share!)

Comment author: Crux 07 December 2011 04:15:06AM *  1 point [-]

Something similar happens to me. If I'm talking to somebody and staring them right in the eyes for more than like 90 seconds, my whole visual field seems to go totally haywire and I start seeing multiple, partial images of their face stacked on top of each other, rotated randomly, and bleeding into each other.

It's of course very difficult to explain what it looks like because of how unfamiliar the patterns are (and thus how hard it would be to remember them in high enough detail to draw or whatever), so a real explanation will most likely have to wait until there's technology available to simply scan my visual field onto a monitor, but it's something like what I wrote above.

Anyway, this only happens when I'm so intent on staring them down with absolutely no interruptions for so long that I end up totally overriding my natural inclination to dart my eyes around in the specific pattern designed to scan the room and form a good representation, so it seems like this phenomenon is simply the chaotic result of overriding the preset updating system for vision.

When I was younger I had a great deal of trouble recognizing facial expressions. For example, it was hard for me to tell whether someone was smiling or barely managing to hold back tears. I could usually figure out which was which from context, at least when the emotions involved were so different. With nuances like the difference between a smirk and a grin, I was completely unable to tell the difference. Ditto for picking up emotional content from intonation and vocal tone.

As a teenager I trained myself to recognize specific small details that reliably distinguish between otherwise similar-looking expressions; tightened muscles, gaze direction, shoulder height and angle, things like that.

I've been diagnosed with Asperger's, ADHD, and delayed sleep phase disorder.

I'm a very visual person. When I read books, my mind creates mental images and associates emotions with those images. If it's a really good book, the experience is very similar to dreaming. My conscious self is utterly submerged, and I live vicariously through the character. Six hours later (I'm a fast reader), the dream ends and I set the book down, and become myself again, and find I have visual slideshow of the entire book. I have never noticed a typo in a book. I remember virtually every fact about every book I've ever read, so long as it has some sort of narrative I can use to construct these images. So for example, I can read a history book once and never forget. I can look at a map, and navigate to anywhere on that map. I have an excellent sense of direction. I can close my eyes, and imagine myself anywhere I've been. I know it sounds like I have a photographic memory, but not really. If you gave me those tests where they show you a picture with a bunch of things, then ask you to repeat them back, I'd do pretty normally. My memory is average for details, excellent at the big picture.

I like to daydream. I have a bunch of different daydreams, and they function sort of like a screen saver for my brain. If I'm not doing anything mentally taxing, I turn on one and tune the world out. I can still remember as a child imagining all my stuffed animals as a council, sitting in a circle and doing something. Most involve a faceless, nameless protagonist who has some sort of magical powers. There are almost never meaningful relationships, and never names, in these daydreams. It's kinda creeps me out, what this fact says about me. These daydreams are very similar to what I experience when reading a book, in form if not content. These stories always involve some sort of enemy that needs defeating. Most run several years, until I get bored of them. I use them to help fall asleep. If anyone is interested, I could post one here.

I also have a really strong reaction to music. I can sit and listen to the same song on repeat for an hour, and I might as well be high, given how differently I think.

I mentioned earlier that books swallow me up, and spit me out later. I'm not capable of analysing anything I read critically the first time through. I have to go back and read it again, as an outside observer.

I have a bad habit of getting into emotional feedback loops. The need to control my emotions was what led to my current interest in rationality, and eventually here to Less Wrong. I would be a very different person if I hadn't needed to master my emotions at such a young age.

Hey, I have those too! I always assumed it was a natural outgrowth of normal kid fantasies (being a magical hero and facing evil, no meaningful relationships) that for some reason I just never gave up on. As I've gotten older I've noticed certain tendencies in the way my protagonist acts and relates to others that have given me insight into myself, and I've stopped using them as a sleep aid because sometimes the adventure was interesting enough that I would deliberately stay awake so I could keep generating the next part.

Oftentimes, if I need to fall asleep I'll pick a really peaceful one. When I was younger, I had one where I was a full sized person in a world made entirely of legos, including tiny living lego people. I'd fall asleep, dreaming of building secret tunnels under the ocean, vast cities with towers a mile high, train tracks for the lego people that climbed mountains that rose above breathable atmosphere to reach secret veins of special legos. It was only during the day that floods, earthquakes and rival lego people threatened.

On a related note, I have such awesome ideas for a Minecraft mod.

There's a thread running through Methods of Rationality on the implications of patterning your developmental schema on the coming-of-age narrative typical of epic fantasy. (Haven't been able to isolate any specific examples there, but similar topics come up in "Formative Youth".) I'm pretty sure that sort of thing is very common among members of our particular tribe, and it's a topic that I'd love to see explored in more detail; unfortunately, no one I know of has ever approached it in depth, let alone with much rigor.

Might just be another holdover from the EEA, come to that; it's a lot easier to be a hero and save your social world when your social world consists of fifty-odd people, all of whom you know and maybe half a dozen of whom share your particular skillset. But hither lies a Just-So story.

patterning your developmental schema on the coming-of-age narrative typical of epic fantasy.

I don't think I do that, there was never any doubt in my mind that it was just a story (eg. at several points over the years I've gotten bored of 'me' but not of the universe I've spent hours creating, and started following another character instead. Or introduced long timeskips so I don't have to narrate boring but necessary-to-my-current-plot events).

I'd say that if anything, I absorbed less from all the fantasy and sci fi tropes I read as a kid and teenager than most people. It never occurred to me as a kid that I should be modelling any part of my behaviour after the people in books.

I experience romantic longing as a warmth starting in my heart which radiates outwards depending on intensity. Normally it only gets to about my upper lungs, but sometimes it makes it through my torso and a little bit down the upper parts of my arms. It feels slightly pressurized, but is incredibly pleasant.

Connectedness feels similar to that, but cold and associated with blue, with weird sensations in which my head either feels floating, or my arms don't feel separate from the world. This is a very rare feeling to have much of, normally when it happens it only occupies a section of my heart.

There's an interesting chapter in Surely You're Joking, Mr. Feynman! in which Feynman describes trying to see if he can count while doing other activities (he can't, for many of them). He finds that a friend can perform the task easily. Here is an excerpt.

I experience something that may be perfectly normal, but I've often wondered if anyone else has it. When I imagine myself or someone else getting hurt, for example when reading about some accident, I often feel a strange, tingling sensation in my skin, especially the insides of my legs, usually starting at the thighs and going down farther if the sensation is stronger.

I get that too, but it moves around and sometimes hurts.

I get no feeling like this at all.

I'm not sure if this is what you are looking for, because it is a developed bias as opposed to something congenital in my cognitive architecture, but...

When I was a child, I used to receive a lot of hand-me-down clothing from from a relative. Their family was better off than mine, but the age difference was just enough that their fairly-expensive clothing was suffiiciently out of style and a source of teasing for me through much of my childhood. Consequently, I have a bias against used goods. For example, I'd much rather buy a new Honda or Ford than a used Mercedes of equivalent value. The used luxury good would have to be A LOT more valuable than the new standard good before overcoming this preference.

Perhaps a separate discussion thread on idiosyncratic biases would be useful?

Mild prosopagnosia -- I know it's not total, but it can be hard to tell where the line is because with people I know well, I have an abundance of other cues for determining their identity. Watching a film or TV show, I can keep the characters differentiated just fine, but it's hard to recognize actors across different performances (with a few exceptions).

I have very strong empathy if you go by the impact of others' emotions on me, and my ability to detect them; it's actually quite overwhelming. I've learned a few tricks for displaying it socially, but they only work at the best of times. This is probably related to my being autistic (I'm not sure how to describe my functional level -- it seems to be very high or very low, but seldom between). I also apply it broadly -- even plants routinely provoke an affective response..

I have intense, immersive visions and "spiritual" experiences from time to time; in the past, they gave me a lot of trouble, until I practiced ritual magic (note: I don't believe in anything literally supernatural) for a while and learned how to channel into comfortable realms of imagery.. This is probably related to me being diagnosed as schizotypal.

I'm a weird hybrid of introvert and extrovert: being without contact or space for long enough seem to be equally-draining and unpleasant experiences. I need plenty of both.

I'm synaesthetic: sound maps to bursts of colour, some sounds map to touch sensations, body language maps to colour/flavor combos that I perceive around the person, and concepts are...complicated. I basically seem to manipulate them as 3-dimensional surfaces of an n-dimensional object. Experiencing logical arguments (which are carried in but not solely determined by the words used) is a matter of trying to trace a continuous line between two points on different faces of the object, an unknown number of permutations away in 3-space. Gaps in the argument, my understanding, or the concepts involved will result in an inability to finish tracing that line. Finally, I can mentally simulate the texture of an object's surface just by looking at it.

I sometimes lose the ability to communicate verbally, or maintain balance, when stressed, exhausted, drugged or hungry.

I've been emotionally polyamorous as far back as I can remember.

My orientation seems to be undefined; I will often experience my attraction to others as specifically same-or-differently gendered after the fact, but it doesn't appear to be a primary criterion for evaluating initial attraction to others. Some nontrivial portion of my attraction just doesn't invoke gender at all, though I'm neither blind to it nor disinterested in it. At this point I have no social hangups about pursuing a partner of any gender; I also don't seem to have any inbuilt limits on how many partners I can feel for; only time and resource constraints seem to affect the size of my concurrent dating pool.

Odd quirk: I can't see stereograms, and am unaffected by some optical illusions. Despite this, I am very easily hypnotised, and quite susceptible to mind-altering substances.

Very hedonic, very intensely affected by my emotions except when there's a crisis (I can be overwhelmed with ennui, sadness, anxiety or frustration; it impairs my self-control but not reflectivity, which leads to frequent embarrassment) but seem to transform into a very rational, reflective, and controlled person when disaster strikes. It also kicks in when others are very emotional.

how are you a beautiful and unique snowflake?

An invitation to talk about myself? Yay!

First of all: complex machinery is universal.

As for me? I'm smart, curious, I get math, I'm good at teaching, and I try to reconcile all my knowledge with itself. These are probably normal for non-impaired, non-darkside people.

I can't think of anything transnormal.
