Pervasive developmental disorder not otherwise specified (PDD-NOS) represents up to two-thirds of autism spectrum disorders; however, it is usually described in terms of the symptoms not shared by autism. The study explores processing of neutral and emotional human stimuli (by auditory, visual and multimodal channels) in children with PDD-NOS (n =…

Autism involves various perceptual benefits and deficits, but it is unclear if the disorder also involves anomalous audiovisual integration. To address this issue, we compared the performance of high-functioning adults with autism and matched controls on experiments investigating the audiovisual integration of speech, spatiotemporal relations, and…

Two experiments were conducted to examine (a) the relationship between the structural characteristics (i.e., bout duration, inter-response time [IRT], pitch, and energy) and overall duration of vocal stereotypy, and (b) the effects of auditory stimulation on the duration and temporal structure of the behavior. In the first experiment, we measured…

This literature review aims to interpret behavioural and electrophysiological studies addressing auditory processing in children and adults with autism spectrum disorder (ASD). Data have been organised according to the applied methodology (behavioural versus electrophysiological studies) and according to stimulus complexity (pure versus complex…

This study examined the ability of young children with autism spectrum disorders (ASD) to detect affective correspondences between facial and vocal expressions of emotion using an intermodal matching paradigm. Four-year-old children with ASD (n = 18) and their age-matched normally developing peers (n = 18) were presented pairs of videotaped facial…

The current study aimed to identify specific stimuli associated with music that served as an establishing operation (EO) for the problem behavior of a 6-year-old child with a diagnosis of autism. Specific EOs for problem behavior evoked by auditory stimulation could be identified. A differential negative reinforcement procedure was implemented for…
