In another study, Simon Baron-Cohen and others at the Autism Research Centre at the University of Cambridge tested Tammet's abilities in around 2005.

He was found to have synaesthesia according to the " Test of Genuineness-Revised " which tests the subjects ' consistency in reporting descriptions of their synaesthesia.

He performed well on tests of short term memory ( with a digit-span of 11. 5, where 6. 5 is typical ).

Conversely, test results showed his memory for faces scored at the level expected of a 6 – 8 year old child in this task.

The authors speculated that Tammet's savant memory could be a result of synaesthesia combined with Asperger syndrome, or it could be the result of mnemonic strategies.
