10% is not very rare. I expect it is much rarer than that. Not sure they are talking about exactly the same thing, but found there references, following.
Dan http://en.wikipedia.org/wiki/Photographic_memory Dr. James William Monroe had the ability then known as Epidetectorial Memory, only present in one person in every 500. Here, the brain is able to retain and recall images it has captured for the duration of its functional ability. http://www.sciam.com/askexpert_question.cfm?articleId=0001148F-EAB0-1E3A -82FC809EC5880000 The vast majority of the people who have been identified as possessing eidetic imagery are children. The prevalence estimates of the ability among preadolescents range from about 2 percent to 10 percent. And it is an equal-opportunity phenomenon--there's no gender difference in who is likely to be an eidetiker. Although it is certainly controversial, some researchers also believe that eidetic imagery occurs more frequently in certain populations of the mentally retarded (specifically, in individuals whose retardation most likely stems from biological, rather than environmental, causes) and also among geriatric populations. With a few notable exceptions, however, most research has shown that virtually no adults seem to possess the ability to form eidetic images. -----Original Message----- From: M. G.

I wonder how many children lose that ability after enough vaccinations, medications, fillings, and lousy food... <sigh> Be well, Mike D.
