I was wandering around the face tests page http://www.faceblind.org/facetests/index.php and found that they are asking for participants who have face recognition problems. If you're interested, here's their contact page:
http://www.faceblind.org/facetests/index.php

Also, I'm collecting some data on face recognition in ASCs, here's my survey if you wanna fill it out here or PM me or email me ([email protected]):

1. If you had to rate your face recognition skills, would you say: excellent, average, poor, or face blind?

2. What's your age?

3. Are you male or female?

4. Currently diagnosed?

5. If you are diagnosed, what’s your precise diagnosis? Asperger’s? HFA? PDD-NOS? Autism? ASD?

6. At what age did you begin speaking? Early (11 months or under), average (12-15 months), late average (16-23 months), or late (24+)?

7. Did you have pronounced echolalia as a child?

Face Recognition Memory

Out of 20 familiar faces, you correctly responded that you had seen 17 faces before.

Out of 30 unfamiliar faces, you correctly responded that you had NOT seen 28 faces before.

Overall, you got 90% correct! The average score on this test is 85% correct.

Object Recognition Memory

Out of 20 familiar eyeglasses, you correctly responded that you had seen 16 eyeglasses before.

Out of 30 unfamiliar eyeglasses, you correctly responded that you had NOT seen 26 eyeglasses before.

Overall, you got 84% correct! The average score on this test is 86% correct.

Verbal Recognition Memory

Out of 12 sets of names, you correctly chose the familiar name 10 times.

Overall, you got 83% correct! The average score on this test is 77% correct.

Nothing wrong with my memory, it seems - and I have already taken sleeping tablet ready for bed. Would have been higher if I hadn't, surely. Sleeping tablets aren't great performance enhancing drugs. So does this mean I'm not AS?

I took a similar test last year. I am not face-blind. In social contexts, I sometimes forget names, but remember people OK.

No, not at all. Although there does seem to be a higher portion of auties who do have face recognition problems (more than the general population that is). But that doesn't mean there aren't many auties who are average or even superior in face recognition.

For myself:

Face Test:
Familiar = 19/20
Unfamiliar = 30/30
98% correct, 91st percentile

Object Test:
Familiar = 16/20
Unfamiliar = 29/30
90% correct, 65th percentile

Names Test:
8/12
67% correct, 25th percentile

I'm bad at names. :?

I've taken this before, from what I remember I got 65th percentile on the verbal recognition test, 12th percentile on the facial recognition one, and 2nd percentile on the object recognition one. I was surprised by the verbal results, because I generally score above the 99th percentile on my ability to learn new words, but I memorize new words by imbuing the word with the "feeling" of their semantic meaning. That totally doesn't work with names, though- at least names of people you don't know.

I know I have a harder time learning words than other types of visuals-- but ESPECIALLY names. Names rarely have a concrete image you can attach to them except for the identity of the person, but then there's little associative meaning to that. It's like attaching a random number to a person almost.

Although I do have an easier time remember numbers than letters, so it'd prolly be better for me if we were all numbered, lol.

I started wondering about the Names Test. Did anybody else notice that all the names presented were EXTREMELY English names? I wonder if that might have some effect on testing, like is it easier for Brits to perform the test because they're more familiar? OR is it the opposite and easier for non-Brits to remember the names because they're a NOVEL stimulus.

Thoughts? I really think this test should be made for each nationality-- at least each English speaking nationality, because I'd think that might have some effect on peoples' results.

For me the names part was extremely easy. I have an excellent memory for written words, so that was the easiest part. I did notice that they were pretty Brit sounding names, but I guess (having grown up there) I really didn't think that much of it.
