The present study aimed to evaluate the presence of dissociations in computation skills, in a group of high-functioning autistic patients. We used the NECO-Battery (1994) which separately assesses each sub-components of number processing, arithmetical and numerical abilities. Preliminary results failed to reveal dissociations between the different tasks under investigation. The autistic subjects showed intact performance on all of the battery's tasks. These results incite the need for detailed case-studies of prodigious autistic calculators with more sensitive paradigms, like chronometric tasks, in order to reveal possible dissociations in the computation abilities.
