Abstract

Individuals with Autism Spectrum Disorders (ASD) often demonstrate impaired generativity that is thought to mediate repetitive behaviors in autism (Turner in J Child Psychol Psychiatry, 40(6):839–849, 1999a). The present study evaluated generativity in children with and without ASD via the use-of-objects task (Turner in J Child Psychol Psychiatry, 40(2):189–201, 1999b) and an Animals Fluency Task (Lezak in Neuropsychological assessment. Oxford University Press, Oxford, 1995). Groups differed significantly on two of four metrics from the Animals Fluency Task and two of seven metrics from the Use of Objects task. In the ASD sample, no significant relations were found between generativity and repetitive behaviors. Significant relations were found, however, between performance on the Animals Fluency Task and communication symptoms. Results replicate reports of generativity deficits in ASD and suggest that impaired generativity may reflect communication deficits that are characteristic of the disorder.
