Abstract This study aimed to identify the nature and extent of receptive and expressive prosodic deficits in children with high-functioning autism. In a data-based group study, 31 children with high-functioning autism (HFA, excluding Asperger's syndrome) and 72 typically developing controls matched on verbal mental age completed a prosody assessment procedure (PEPS-C). Children with HFA performed significantly less well than controls on eleven out of twelve prosody tasks (p < .005). Receptive prosodic skills showed strong correlation (p < .01) with verbal mental age in both groups, as did, to a lesser extent, expressive prosodic skills. Receptive prosodic scores also correlated with expressive prosody scores, particularly in grammatical prosodic functions(turnend and prosodic phrasing/ chunking). Prosodic development in the HFA group appeared to be delayed in many aspects of prosody and deviant in some (e.g. accent tended to be placed early in focus tasks and Same items were often perceived as Different in auditory discrimination tasks). The study demonstrates that receptive prosodic deficit, expressive prosodic skills, and language development are closely associated in the condition of autism. Receptive prosodic skills would be an appropriate focus for clinical intervention, and further investigation of atypical expressive prosody and the relationship between prosody and social skills is warranted.
