Language and Cognition in a savant’s mind Ianthi Maria Tsimpli Aristotle University of Thessaloniki and NIAS Christopher is a polyglot-savant with exceptional language learning abilities, atypical autistic behaviour, apraxia and visuo-spatial deficits. I will present the attested strengths and weaknesses in Christopher’s languages, in his language learning abilities and in other aspects of his cognition, mainly on false-belief tasks and memory. It will be argued that asymmetries are found within language abilities indicating that language is an umbrella term including properties which are more or less sensitive to non-linguistic cognitive abilities.
