V.S. Ramachandran (A 2005 article in Science reported that Tammet had been tested by V. Ramachandran and team, which “now plans to investigate the multiplication skills of Tammet.” I wonder what happened to that project?)
John M. Wilding
(Dr Jamie Ward the UK synasthesia researcher wrote about Tammet in his book The Frog Who Croaked Blue and evidently had a discussion with Tammet, but I've found no evidence that Ward studied Tammet formally.)
(Prof. Allan Snyder in Australia has commented on Tammet as a case of savantism but I don't think he has studied Tammet first-hand)
(a quote from page 230 of the book Moonwalking With Einstein by Joshua Foer: "When Anders Ericsson invited Daniel to visit FSU to be tested according to his own exacting standards, Daniel said he was too busy to make the trip.")
(a quote from a review of one of Tammet's books in the Journal of Autism and Developmental Disorders: "He also contributes to our knowledge base by volunteering to participate in dozens of brain studies." Where have these "dozens" of brain studies been published?)

[This is a brief and sychophantic book review which includes some highly unlikely claims; that synaesthesia is a rare condition; that Tammet learned Icelandic in only four days and that Tammet was at the time of publication “volunteering to participate in dozens of brain studies.” I can only assume that the vast majority of those brain studies must be still unpublished, because I have only been able to find records of a few.]
