When I didn't think about it, And trusted my instincts and feelings instead. I always got it right. And figured it out almost instantly. But logically I can't explain that. It was like magic.
Not often, but supplying only the eyes is a good way to bring the scores down into a more useful range for the test. Assuming that eye-specific recognition ability is a close enough proxy for overall ability, of course.
Personally I don't think this test has anything to do with Asperger's. My feeling is that facial recognition is to some extent an acquired skill like anything else, and that the lowest scores are largely going to go to the people with the least experience in attending to the emotions of others.
When they are being lied to. That is, every day.
I think it's harder to control both, a disparity between the two suggests something is amiss. Also, "the eyes are the windows of the soul" has some basis in human behaviour IMO.
