Test Yourself for Face Blindness!

I’ve mentioned before that I am rather significantly face blind; I find it very difficult to recognize faces, even my own, or those of people I know well. The July issue of The American Journal of Medical Genetics Part A has published a new study about the disorder, finding that it is inherited in 1 of 40 people (and autosomal dominant, affecting men and womean equally and passed down from parents to children if just one defective gene is transmitted), and there’s a New York Times article about it that has a fun link where you can test yourself – you may be surprised!

Dr. [Heather] Sellers, a professor of English at Hope College in Holland, Mich., has a disorder called prosopagnosia, or face blindness, and she has had it since birth. “I see faces that are human,” she said, “but they all look more or less the same. It’s like looking at a bunch of golden retrievers: some may seem a little older or smaller or bigger, but essentially they all look alike.”…

The researchers say the phenomenon is much more common than previously believed: they found that 2.47 percent of 689 randomly selected students in Münster, Germany, had the disorder…

Dr. Grüter is himself prosopagnosic. His wife and co-author, Dr. Martina Grüter of the Institute for Human Genetics at the University of Münster, did not realize he was face blind until she had known him more than 20 years. The reason, she says, is he was so good at compensating for his deficits.

…but the important thing is that the article in The New York Times includes a link to test yourself for face blindness! There are two different tests, both of which ask you to recognize faces without the benefit of ears or the major facial hair.

On one of the tests (the ‘Famous Faces’ test), I scored a pathetic 9 faces recognized out of 30, or 30%, where the average normal score is 85%! Plus, I was slow: it took me 30 to 45 minutes to complete, where Larry Helmerich didn’t need more than a few minutes, and John Blackburn literally finished in a single minute; their scores are shown below.

Test yourself for face-blindness (and tell me your score!)

Notes:

Low Scorers: Note that the seven lowest scorers on the Famous Faces test are all relatives of mine.

Sally Helmerich (FF: 60%) says, “I recognize people by their voices.” Before Chris Ravenscroft (FF: 60%) knew this, he said the exact same thing! Apparently, by the time that you’ve gotten down to 60% on the Famous Faces test, you’ve got an appreciable deficit.

Tom Harvey writes: “On the famous faces test, I was slightly screwed up by some previous insider knowledge (Jeff mentioning XXX being in the test). I also found myself declaring unfamiliarity with certain people that I’d watched entire movies that they were in (XXX, XXX) or people that are generally ubiquitous even to celebrity-ignorers such as myself (XXX). I could attempt to justify this, but maybe my score should have been lower.”

The Famous Faces test was insanely difficult for me, as my score (FF: 30%) attests. I’d tell you some of the mistakes I made, and you’d howl, but it would keep you from being able to take the test.

On the Old-New Faces test, I felt as if I were cueing on things like how the photographs were lit, rather than genuinely recognizing or not recognizing the faces. I later wrote to the researchers, recommending that they use different photos of the same subjects, instead of always using the same photos for the same subjects, and they said that indeed, they do that now in their non-public lab tests, because they found that people who had a good visual memory but who had poor facial recognition were able to “cheat” the test. [Edit: that improved test, the Online Cambridge Face Memory Test, has now replaced the Old-New Faces test on the web site, but I haven’t yet gone back and tried it.]

High Scorers: On the Famous Faces test, my wife Sylvia got 100%, our son Sean and my sister Jan’s son Craig both got 97%, while on the Old-New test, Sean has the top score of 96%.

Sylvia (FF: 100%) has always been Scary Good at recognizing faces, especially out of context, which I can never, ever do.

John Blackburn (FF: 100%, Old-New: 92%) has near-perfect pitch, and yet is also great at recognizing faces!

I once sat at a table with Bill Standley (FF: 95%, Old-New: 94%) and about 9 other co-workers. We had all been asked to bring in baby pictures of ourselves, and they were shuffled up, and then the game was to match up the babies to the adults. They all looked like a bunch of golden retrievers to me, but Bill Standley just whipped through those pictures, 100%, like the babies were sitting there at the table next to him.

    Celebrity faces: 100%, 1 minute

    On the Old-New:
    “Out of 20 target faces (ones you learned in the first part of this test), you correctly identified 16.
    Out of 30 nontarget faces (ones that didn’t learn in the first part of this test), you correctly responded that you had not seen 30 of them.”

    I win!

    Tom Chappell, you are a strange man. Though it’s interesting – I qualify as “normal” at 86%, but often have problems grasping names of someone I’ve met before when I come across them unexpectedly. Perhaps it’s related to my subpar (amongst this group) face score!

    Celeb Faces: 100%
    Old-New Faces: 86%

    – – – – – – – –
    Out of 20 target faces (ones you learned in the first part of this test), you correctly identified 18.
    Out of 30 nontarget faces (ones that didn’t learn in the first part of this test), you correctly responded that you had not seen 25 of them.

    Overall, you got 86% correct

    The average person with normal face recognition scores about 85% on this test. If you scored less than 75% on this test, this may indicate face recognition difficulties.

    Very interesting. I had no idea…!

    93% on the famous face test. Didn’t try the other one.

    Hah, new benchmark –
    Celebrity: 100%
    Old-New: 96% (19/20; 29/30).

    Behold, the power of youth.

    Darn youth. After chatting with Sean, he took a free pass on one question that I had to disallow, so his score on famous faces is adjusted in the tallies, but he still is right up there at the top of the ranks!

    Hey—I just stumbled on your website from the internet. I think I might have mild face blindness because I fail to recognize people I’ve met more frequently then most people do. I sometimes put out my hand and say, “Hi, I don’t think I’ve met you” and it’s awkward.
    I got 46% on the famous face test and 80% on the other one.

  8. Tom Chappell wrote:

    Hello, Alex! Well, I don’t know if we can call that ‘mild’ — you scored in the bottom 17%, in a field infested with my relatives.

    Consider that the average for FF is 85%.

    ‘Moderate’ at least!

    The thing that continues to amaze me is how very long people can go without realizing that they have a deficit. Heck, I only scored a 30% on Famous Faces. If you search around the blog, you’ll find incredible failures in this area (not recognizing my son, or even myself), and I didn’t realize that I had a problem until I was…what, 42, at least.

    I can’t remember how well I did at the famous faces test, (around average maybe), but it’s not normally VERY famous people I have trouble recognising. For me, once I’ve seen someone’s face enough times or made a huge effort, then I can remember them. But if I’ve only seen you a few times (I’m guessing like Alex above), and you’re surrounded by vaguely similar-looking people, then I have no chance of remembering your face.

    I only just realised how often I rely on cues like clothing and haircut, and consciously observing differences in facial structure to help me. I guess lots of people are so used to doing this that they don’t really realise that most people don’t have to. I love to draw, faces included, so I don’t think I lack in observation skills; I’ve always said that looking at people’s appearances to me is a bit like admiring a work of art – I used to think that was simply because I was artistic and inclined to observe, but I’m now wondering whether part of the reason I observed so much was because I actually had to.

    Finding out the other day that plenty of people on the internet have it in varying degrees has been strangely liberating.

    Now I feel less guilty for all those times I didn’t recognise people I ‘should’ have known (friends’ parents, neighbours, colleagues) out of context, because I’ve let myself accept that it’s NOT that I’m careless or didn’t try hard enough to remember them. Which is why I’ve decided to reply even though this post is years old – keep up the good work, posts like this one mean a lot to me and no doubt many other lurkers.
