This study aimed to explore the recognition of emotional and non-emotional biological movements in children with severe and profound deafness. Twenty-four deaf children, together with 24 control children matched on mental age and 24 control children matched on chronological age, were asked to identify a person's actions, subjective states, emotions, and objects conveyed by moving point-light displays. Results showed that when observing point-light displays, deaf children showed impairments across all conditions (emotions, actions, and moving objects) compared with their chronological age-matched controls but showed no differences across subjective states. The results are supportive that deaf children present developmental delays in their biological motion apart from the ones relative to their own mental state, and this may be interpreted in relation to the expertise they have acquired in decoding action toward themselves. The findings are discussed in relation to deaf children viewing motion stimuli very ...

Findings from several studies have suggested that deaf children have difficulties with emotion identification and that these may impact upon social skills. The authors of these studies have typically attributed such problems to delayed language acquisition and/or opportunity to converse about personal experiences with other people (Peterson & Siegal, 1995, 1998). The current study aimed to investigate emotion identification in children with varying levels of deafness by specifically testing their ability to recognize perceptual aspects of emotions depicted in upright or inverted human and cartoon faces. The findings from the study showed that, in comparison with both chronological- and mental-age-matched controls, the deaf children were significantly worse at identifying emotions. However, like controls, their performance decreased when emotions were presented on the inverted faces, thus indexing a typical configural processing style. No differences were found across individuals with different levels of deafness or in those with and without signing family members. The results are supportive of poor emotional identification in hearing-impaired children and are discussed in relation to delays in language acquisition and intergroup differences in perceptual processing.

High-functioning adolescents with ASD and matched controls were presented with animations that depicted varying levels of social interaction and were either accompanied by music or silent. Participants described the events of the animation, and we scored responses for intentionality, appropriateness, and length of description. Adolescents with ASD were less likely to make social attributions, especially for those animations with the most complex social interactions. When stimuli were accompanied by music, both groups were equally impaired in appropriateness and intentionality. We conclude that adolescents with ASD perceive and integrate musical soundtracks with visual displays equivalent to typically developing individuals.

In this article, we examine the extent to which children with autism and children with learning difficulties can be discriminated from their responses to different patterns of sensory stimuli. Using an adapted version of the Short Sensory Profile (SSP), sensory processing was compared in 34 children with autism to 33 children with typical development and 22 children with learning difficulties without autism. Both clinical groups showed high symptoms of sensory impairment compared to controls. However, the autism group displayed higher levels of impairment in auditory hyper‐sensitivity and visual stimulus‐seeking factors compared to controls and the learning‐disabled group. Using a discriminant analysis we found a combination of four factors which correctly classified 80.9% of the children. Implications for the diagnostic value of sensory processing in autism are discussed.

Whilst hypersensitivity to pitch information appears to be characteristic of many individuals with autism spectrum disorders little is known about the implications of such a tendency for language acquisition and development. Discrimination of systematically varied pitch differences between pairs of words, nonwords, and nonspeech pitch contour analogues was assessed in children with autism spectrum disorders (ASD) and matched controls. The findings revealed superior performance in ASD, although, like controls, discrimination of pitch in speech stimuli was poorer in this group than for nonspeech stimuli. Whilst it was hypothesized that enhanced processing of speech pitch would correlate negatively with receptive language skills in ASD, the findings did not fully support this, and enhanced discrimination skills were observed in individuals without significant language impairment. The implications of these findings for understanding heterogeneity of language ability in ASD are discussed.

A single case study of a musically untrained autistic child is presented. This individual demonstrates absolute pitch ability and outstanding analytical capacities within the musical domain. It is argued that his musical information processing style might be accounted for by a tendency to focus on local rather than global aspects of musical stimuli, and in addition illustrates a case study of exceptional ability in the absence of 'musical talent'.
