Out of curiosity, what is the correct answer to the example Raven's item? One of the answer candidates popped out to me immediately as the most likely one, and I'm interested to know whether that's a sign of me having superior pattern recognition ability or whether a part of me just wants to believe that.
I'm pretty sure it's 2 (same as Vaniver, gwillen, and Alicorn). Was that what popped out at you?
It didn't take me less than 10 seconds to come up with this (I'd be surprised if it was less than 20 or more than 40 to find it and check, but I didn't check the clock). I tried to figure out the pattern without priming by looking at the possible answers, so there wasn't even really a chance to have the right answer pop out in this fashion.
ETA: I have taken Raven's Matrices before, so I was ready.
Nope: I got the fourth one. Guess it was just my brain playing tricks at me, then. :)
(I tried to do it using basically just unthinking pattern recognition, looking at the sequence of patterns as a sequence of movement: somehow, using that criteria, the fourth one seemed to display "the most similar kind of motion" as compared to the above examples, even though a more conscious analysis suggested that it seemed to be breaking some of the rules of the above sequences, and I couldn't come up with any verbal summary of the rule. But it still just felt so right somehow.)
I, too, tend towards mentally overlaying the tiles and looking for movement-patterns as I jump from one tile to another.
In this case, I saw the middle row as a flash of "fire" that burned away some of the first row, and what remained was the content of the third row. (And it worked with columns too, which is how I knew that this was the correct visualization).
What do you think about this? http://www.pnas.org/content/100/19/11163/F2.medium.gif
Psychologists make a distinction between that sort of fuzzy similarity judgement and rule-based analytical reasoning (and the social/cultural factors that predispose people to one or the other). They're both valid ways to think about things in different contexts, but Raven's matrices are definitely rule based and you should probably avoid fuzzy holistic reasoning when trying to solve them correctly.
(In the flower example, one is the holistic grouping and the other is the rule-based grouping)
I got 6 as the answer, basing it on 1. presence of inner circle 2. outer box apparently following a pattern.
But there's a high chance i'm privileging my observations.
You could also do a row-wise XOR on every feature and get 2. Which for me seemed like a pretty obvious solution to me so I went with it.
