There’s a link to the Cambridge Face Memory Test at the webpage for the radio show.

Sad but not surprising that prosopagnosics can be mistakenly perceived as having a personality issue rather than a perception issue.

I’ve got an anecdote that is rather like the opposite of the one shared by Dr Karl in the radio show, in which he came to understand that he had an unusual problem in recognizing fellow-students at university. Just this week I recognized (with no foreknowledge) a student that I once shared a tutorial group with when the student made a very brief appearance as an actor in a television advertisement. Nice! I wish him the best of luck in his acting career. He was working in a series of health promotion ads that consistently feature better acting than that often seen on the TV shows.

In case you are wondering, the music used in the radio show were two hits of the 70’s; that famous tune by Grace Jones and at the end the big hit by Roberta Flack.

The search for an effective intervention for prosopagnosia continues, but at least the knowledge of what is going on must be some help to people who face this challenge.

Story on super-recognizers on Australian radio with link to test

This story with an interview of Australian researcher Dr David White was broadcast last year. I’m not actively trawling for items about super-recognition to post about here, so I only just came across it by chance.

Readers of this blog might be interested in the download linked to from the RN web page for the story, which is a difficult face matching test. I’ll give you a tip and advise to only look at the faces as you go and record your own answers as you go, and check them later.  I got only five out of eight correct.

Don’t confuse poor face memory with aphasia

I know this fascinating article is from 2013, but it makes such an important point about face recognition that I want to bring it to your attention, if you weren’t already aware of it. The ability to remember a person’s face is a different ability than the ability to name the person the face belongs to. These abilities are evidently processed in different areas of the brain. Unfortunately, there is no direct link to the journal paper this article summarizes, so I cannot quickly determine whether the test using the faces of famous people is the same as the “Famous Faces” test that I have previously mentioned at this blog (and done myself). It does sound similar to one of the tests offered here, free of charge: https://www.testmybrain.org/

Supermatchers super-recognizers, same thing, isn’t it?

Passport Problem. Catalyst. ABC. February 24th 2015. http://www.abc.net.au/catalyst/stories/4185916.htm

Why are the science journalists at the Catalyst team trying to distance this story from the existing body of research and writing on the same subject as the story, by using a new term for people with tested elite ability in face recognition? As far as I can tell, the skill is the pretty-much same as the skill measured by the CFMT, which I believe is recognized by researchers around the world as a gold-standard test of face memory or face recognition.

Calling all supers! New testing opportunity for all, and for some to take part in a study

http://www.testmybrain.org/SupersRecruitment.html

One of the world’s leading researchers in the related areas of face memory, face recognition, prosopagnosia and super-recognition has given me the tip that super-recognizers are wanted as research subjects, and they are being recruited through the above web link which appears to be associated with the long-running online research and volunteer testing website TestMyBrain. I have also been advised that for this study the researchers are looking for subjects who reside in the continental states of the United States of America, but if that isn’t you, and you get a very high score in the test and follow the instructions and send the researchers your score there is some possibility that some time in the future you might be sought for some other study. Of course, you don’t have to share your score with anyone, and you might wish to take this test simply to get a good idea of what level of face memory ability you have. Maybe you suspect that you might have prosopagnosia (disability in face memory) or you might just want verification that you are what we call normal. When I finished the test I was given my own score and also an average score, so I guess you could use this test to compare yourself against the norm. I am not sure whether the researchers might object to curious people rather than potential super-recognizer study subjects doing the test. If that is a problem, they can let me know. I am also not 100% sure whether or not all scores from doing the online test are used as anonymous research data, as is the case in some websites that offer online neuro-cognitive testing, or is this testing merely used to screen eligible candidates for an upcoming study of super-recognizers. I suspect the latter. You should contact the researchers yourself if you have any questions.

This is an important new opportunity to undergo a test of face memory ability because this test is a version of the Cambridge Face Memory Test, a test that has a well-deserved reputation as a scientifically valid test of face memory, and it has been quite a long time since I’ve been aware of any version of the CFMT being openly available to take through the internet. This test appears to be a third version of the CFMT, the first being a 72 question short form, the second version being the 102 question long form, and this version being another 72 question version but with new faces (I’m pretty good at judging these things) that are computer-generated. All versions have all male faces. I recall reading somewhere that the faces used for the first version of the CFMT are based on real American Caucasian people. It’s probably a good idea to use computer-generated faces for the latest version, to avoid the possibility that real people might be stopped in the street by super-recognizers exclaiming “Hey! You’re one of those blokes in that face recognition test!”

For people hoping to find a way of documenting their own status as a super-recognizer this is an opportunity to do a scientifically credible test of face recognition and also get access to your own written score in that test along with an average score, but be advised that I did not automatically get any printed statement verifying that my score was in the range of super-recognizers, and I did not notice any printed range of scores for super-recognizers given anywhere in the testing. It was pretty obvious from the results page that my score was in the elite range though. I have been advised by someone who should know that a score of 69 is considered to be in the super-recognizer range. I found this test to be harder than the first version of the CFMT, and I suspect that super-recognizers might find that they don’t bump their heads on a ceiling with this test. Information that I have at hand suggests that the average score on the new 72 question version of the CFMT is lower than the average score on the old 72 question version. For super-recognizers who are eligible and willing to take part in the study after they have done the screening test I guess there might be further opportunities to document their status as a super-recognizer and meet researchers, but I can only guess. At least your participation would give you the right to refer to yourself as a “Citizen Scientist”, which sounds fairly impressive. As I live in Australia I will not be able to participate in the study so I can’t advise you where it all leads. My best tips for people interested in documenting their score are to follow the instructions carefully, be ready to take your own full-colour print-outs of any screen with your score on it and if you have questions contact the people behind the test.

This isn’t the first time that I’ve been asked by a researcher from an overseas university to help with recruiting supers for research studies, and I’m happy to help with genuine requests because I like to see science moving forward and I know that participating in research can be interesting and sometimes rewarding. The website TestMyBrain is associated with many genuine researchers of social psychology, neuro-cognition, visual perception, face perception and various interesting and important things, including researchers from the Social Perception Lab at Dartmouth College and researchers from the prestigious Harvard University. Researchers linked to the website appear to be generally based at universities and colleges in the United States of America.

In case you are curious, my score on the new test is 69 out of 72 and I have been advised that my score is in the super-recognizer range. As I have written about in old posts at this blog, I have also done the earlier versions of the CFMT. The first version of the CFMT was either the first or the second face memory test that I ever did, and I was amazed at the time to get perfect scores on both online tests I did that day. I had gotten 72 out of 72 on the old version of the CFMT, but till then I had no idea that I was a super-recognizer. In 2010 through an Australian university I did some face memory tests in person and I firmly believe one of those tests was the long form of the CFMT, my score in that one given as “96%”, which presumably means I got 98 correct out of a possible 102 correct, which is well within the super-recognizer range, based on data about supers from the 2009 journal paper that launched the concept of the super-recognizer. As I’ve stated earlier, I have at hand data that indicates that the new CFMT is more difficult than the earlier version of the same length. The norm for the first version was given as 80% correct face recognition (presumably an average score of 57.6 out of 72) while the average for the new version is currently cited as a score of 52.49 (out of 72). So it appears that the CFMT has become more difficult while my face memory ability has not measurably changed in the four years since it was first tested.

I wish the researchers planning to study supers the best of luck and I look forward to reading a published report of what they find. We are all working to help people and to advance scientific knowledge, and those are for sure two noble causes.

Cambridge Face Memory Test- how long is it?

The original short standard version had 72 items or questions in it and the long version had 102, but I have recently read that new versions have been created, and I don’t know anything about them. There is also a children’s version.

This is a link to the journal paper that introduced the concept of the super-recognizer, and you can read about the use of both original versions of the CFMT in this paper: http://www.faceblind.org/social_perception/papers/russell09PBR

New paper about study of face processing in developmental prosopagnosia on oxytocin

The paper is open access, so you don’t need to pay to read the whole thing. Is “face processing” the same thing as “face memory” or “face recognition”? When I’ve got more time I’ll have a good look at this study and see. I have noted that this is a quite small study (10 DPs, 10 controls), so let’s not get too excited about the findings.

http://www.sciencedirect.com/science/article/pii/S0010945213002086

Two bits of interesting information about the Cambridge Face Memory Test can be found within this paper.  The authors advise that some people with developmental prosopagnosia can achieve a normal score on the CFMT by using “effective compensatory strategies”. I’m curious about how that is done, because I thought the CFMT was pretty much cheat proof. It is also revealed that two new versions of the CFMT were created for this study.

I plan to write more about this paper but right now my garden requires attention. And after that the turquoise coastline lined with fine white sand near where we live will require attention.
