Abstract: The question was asked whether a diagnosis of autism or a tendency to repetitive behaviour and preoccupation with a restricted area of interest, were crucial features of idiot-savant talents. Answers by caretakers to a questionnaire on these topics revealed that autistic and nonautistic savants resembled each other closely in preoccupation but differed from controls matched for IQ and diagnosis. In addition, the mentally handicapped showed fewer repetitive tendencies than did autistic controls. It is concluded that independent of diagnosis, preoccupations and repetitive behaviour appear to be closely associated with the manifestation of idiot-savant talents.
