Effects of physical exercise on Autism Spectrum Disorders: A meta-analysis / Michelle SOWA, in Research in Autism Spectrum Disorders, 6-1 (January-March 2012)

This meta-analysis evaluates 16 behavioural studies reporting on a total of 133 children and adults with various variants of the syndrome who were offered structured physical activities either in an individual or a group context. The effects on social and motor deficiencies, two of the three primary symptom clusters of ASD, were normalized to afford a quantitative evaluation. Results pertaining to communication deficits were insufficient to permit classification. All activity programmes yielded significant progress on the measures assessed, but the individual programmes elicited significantly more improvement than the group interventions in the motor and, more surprisingly, also in the social domain. Although overall sample sizes were small, the combined results do permit the tentative conclusion that in terms of motor performance and social skills children and adults with ASD benefit most from individual exercise interventions. Further research of the impact of individual and group interventions on communication deficits in particular as well as studies gauging the extent to which exercise effects depend on ASD symptom severity are warranted.

Internal model deficits impair joint action in children and adolescents with autism spectrum disorders / Astrid M.B. STOIT in Research in Autism Spectrum Disorders, 5-4 (October-December 2011)

The present study investigated the hypothesis that impaired social interaction in ASD reflects a deficit to internally model the behavior of a co-actor. Children and adolescents with ASD and matched controls performed a computerized bar-balancing task in a solo condition (S), and together with another individual in two joint action conditions (J2 and J4) in which they used either two or four hands to control the bar lift. Consistent with predictions derived from the ‘internal modelling hypothesis’, results from the J2 task indicated that ASD dyads were impaired in predicting the occurrence of their partner's response and failed to coordinate their actions in time. Furthermore, results from the J4 task showed that ASD participants used an adaptive strategy to disambiguate their responses from their partner's by regulating opposite sides of the bar during lifting. These findings provide empirical support of theories positing the existence of an internal modelling deficit in ASD. In addition, our findings suggest that impaired social reciprocal behavior and joint cooperative play exhibited by individuals with ASD may reflect behavioral adaptations to evade conflicting or ambiguous information in social settings.
