Teenage super single case study published last year

This study raises questions in my mind about the development of super-recognition. Here’s a case in an adolescent who is nowhere near completing the stages of development of her brain (but does this ever really end?), but she is irrefutably displaying the cognitive talent and characteristics of super-recognizers. How does this information sit with evidence that face recognition is an ability that continues to develop much later than most other cognitive abilities, into the 30s? Will she go on to develop into a super-duper-recognizer as an adult? Has she already reached the peak of her ability and will stay at this level in adulthood? Is the normal trajectory of face memory ability irrelevant to super-recognition?

Where are tests for people who suspect they or their kids have prosopagnosia?

The top search term leading to this blog for the last month has been “prosopagnosia test”, even though this blog is primarily about the opposite condition of super-recognition, and also covers another brain-based peculiarity of mine which is synaesthesia. I also write about prosopagnosia and link to relevant resources because I understand the importance of face memory as a human ability which we are all assumed to possess, but which many people do not possess. I’m sure the recent upswing in interest in testing for prosopagnosia or face-blindness or facial agnosia or a disability in face memory is due to the famous actor Brad Pitt’s recently publicized interview in Esquire magazine in which he revealed that he suspects that he has prosopagnosia, and his poor face memory has had a definite negative impact on his social life. He has been lucky in that an American expert in face memory and prosopagnosia has publicly offered testing and brain imaging to Mr Pitt. This is great, but whether he takes up this offer is his decision. What about less famous people who have similar suspicions about their own face memory ability or that of a person in their life? What about parents who suspect that their child or children might have prosopagnosia? We know that one type of prosopagnosia is developmental prosopagnosia, which affects people from early in life and can run in families and is certainly genetically inherited. Don’t assume that it is a disability that kids will grow out of; as far as I know this is not true. We have good reasons for believing that children who can’t recognize faces and therefore probably have social difficulties and possibly anxiety issues as a result would be especially at risk of being wrongly diagnosed and stigmatized as being on the autistic spectrum. It is very important that people of all ages who might have prosopagnosia be identified, informed and if possible helped. We are in the midst of an upswing in interest in this issue. So where is the help? Where are the tests? Where should Australians or British people wanting to know about prosopagnosia testing go to for help?

After searching thru many dead links I’ve found a link that appears to lead to an online version of the Cambridge Face Memory Test. This is probably the best face memory test available today. There are two versions; the short and the long form. The short version has 72 questions in it. It can be important to know which you did, but I suspect that the test linked to here will give a score in the proper context. http://www.icn.ucl.ac.uk/facetests/fgcfmt/fgCFMT.php

For the testing of children, one of the leading face memory researchers who created the CFMT, Dr Brad Duchaine, and two other researchers, Kirsten Dalrymple and Jesse Gomez, have created the CFMT-Kids, which “…is available to other researchers”, so I’ll guess parents will have to find a face memory researcher in their city (good luck) and do some begging.  I don’t know if this test is available online, but I suspect that it isn’t.  http://w.journalofvision.org/content/12/9/492.short

For help and advice I guess Faceblind.org would be the best place to look on the internet:  http://www.faceblind.org/
