Just an interesting article I thought I'd share.

I thought that this was interesting as well, but pretty speculative given the sampling used.

Nobody IQ>140 was in the sample.

I personally suspect quite strongly that this correlates far more to sensory integration than strictly to IQ. It's just that some of those things are more common in higher IQ samples.


The other thing that I wonder is if you venture further out-- does the inability to spot large objects vanish while the greater tracking ability remains? I'm guessing that it might, as you find HG+ people who can use multiple processing channels simultaneously.

It also seems VERY obvious to me that this is likely to be a purely processing speed correlation. While that certainly matters, it's not everything, either.

Gestalt plays a large role here I think and the article title is a bit misleading - the test is no common or garden eye test. I would expect there to be a positive correlation between strong performance on a test of ability to effectively distinguish figure from ground and overall intelligence.

I'm going to reference this article the next time my wife cuts an inch off her long, curly hair, and complains that I didn't notice.

"The team noticed that people with higher IQs were good at spotting motion in the small circles, but terrible at detecting motion in the larger black-and-white stripes."

One can't see the forest for the trees? Explains why my husband wants to know where the toothpaste is when it's right in front of the cabinet.

This test sounds highly unlikely to pick up many 2e types...

I was thinking that forest and trees are the ends of a brain structure continuum as the Eides talk about ( http://eideneurolearningblog.blogspot.com/2009/08/dyslexia-and-autism-are-opposites.html ), and the trees end correlates well with Verbal subtests and the forest side correlates well with Visual subtests.

So, an interesting study of that hypothesis would be to test people diagnosed with dyslexia and others with ASD with the prediction that folks with an ASD diagnosis will have stronger skills in spotting motion in the smaller circles and those with a dyslexia diagnosis would detect the larger stripes motion.

And those wih dyslexia and asd? :-).

No way of knowing without doing the test but I suspect that both of my rather quirky girls would do well on this sort of test, and my dyslexic/aspire girl possibly better than her "real" iq score.

Based on things I've read, I'd be highly suspect of that pairing of diagnoses. Or it goes to illustrate the weakness of the symptom accumulation DSM method vs. identifying underlying causes.

From my understanding it is extremely common to see aspergers with either dyslexia OR hyperlexia.
