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.
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.
