Effects of water exercise swimming program on aquatic skills and social behaviors in children with autism spectrum disorders - Tue, 02 Feb 2010 10:58:23 PST

The purpose of this study was to determine the effectiveness of a 10 week water exercise swimming program (WESP) on the aquatic skills and social behaviors of 16 boys with autism spectrum disorders (ASDs). In the first 10 week phase (phase I), eight children (group A) received the WESP while eight children (group B) did not. A second 10 week phase (phase II) immediately followed, with the treatments reversed. Both groups continued their regular treatment/ activity throughout the study. Improvements were seen in aquatic skills for both groups subsequent to the WESP. Following phase I, significant social improvements were seen in group A. Following phase II, social improvements were seen for group B, whereas group A merely maintained the improvements they attained through the implementation of the WESP during phase I. Results indicate that the WESP improved aquatic skills in the participants, and holds potential for social improvements.

The atypical development of metaphor and metonymy comprehension in children with autism - Tue, 02 Feb 2010 10:58:23 PST

One of the most noticeable problems in autism involves the social use of language such as metaphor and metonymy, both of which are very common in daily language use. The present study is the first to investigate the development of metaphor and metonymy comprehension in autism. Eleven children with autism were compared to 17 typically developing children in a metaphor-metonymy comprehension task. Cross-sectional trajectory analyses were used to compare the development of metaphor and metonymy comprehension using a child-friendly story picture task. Trajectories were constructed linking task performance either to chronological age or to measures of mental age. Children with autism showed an impaired metaphor comprehension in relation to both chronological and mental age, whereas performance on metonymy was delayed and in line with their receptive vocabulary. Our results suggest that understanding of metaphors and metonyms are severely affected at all ages examined in the current study.

Attentional blink in young people with high-functioning autism and Asperger's disorder - Tue, 02 Feb 2010 10:58:23 PST

The aim of the study was to examine the temporal characteristics of information processing in individuals with high-functioning autism and Asperger’s disorder using a rapid serial visual presentation paradigm. The results clearly showed that such people demonstrate an attentional blink of similar magnitude to comparison groups. This supports the proposition that the social processing difficulties experienced by these individuals are not underpinned by a basic temporal-cognitive processing deficit, which is consistent with Minshew’s complex information processing theory. This is the second study to show that automatic inhibitory processes are intact in both autism and Asperger’s disorder, which appears to distinguish these disorders from some other frontostriatal disorders. The finding that individuals with autism were generally poorer than the comparison group at detecting black Xs, while being as good in responding to white letters, was accounted for in the context of a potential dual-task processing difficulty or visual search superiority.

Effectiveness of special nursery provision for children with autism spectrum disorders - Tue, 02 Feb 2010 10:58:23 PST

The effectiveness of three local authority early teaching interventions for children with autism spectrum disorders (ASDs) was studied. Thirty-three children (2:6 to 4:0 years old) received one of three early teaching interventions: a 1:1 home-based programme, and two different forms of special nursery placement. Measures from the Psycho-Educational Profile, British Abilities Scale, and Vineland Adaptive Behavior Scales were taken over a 10 month period. The study showed moderate effect sizes for improvements in all scales for children attending a generalized special nursery placement, and for those attending a special nursery placement solely for children with ASDs. Children receiving a home-based 1:1 programme with similar intervention hours showed moderate effect sizes for the PEP and BAS but not for the VABS. These data show that special nursery placements can offer benefits to children with ASDs, especially in the area of adaptive behavioural functioning.
