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.

The purpose of this study is to examine the gene by environment (G×E) interaction of the DRD4 7-repeat allele and smoking during pregnancy on ADHD and oppositional behavior in families from the International Multicenter ADHD Genetics project; and further, to test the hypothesis that the direction of effect of the DRD4 7-repeat allele differs between ADHD affected and unaffected children.
Methods: Linear mixed models were used to assess main and interactive effects of the DRD4 7-repeat allele and smoking during pregnancy in 539 ADHD-affected children and their 407 unaffected siblings, aged 6–17 years.
Results: There was some evidence pointing to differential effects of the DRD4 7-repeat allele on ADHD and oppositional symptoms in the affected (fewer symptoms) and unaffected children (increasing ADHD symptoms of teacher ratings). Affected children were more often exposed to prenatal smoking than unaffected children. There were limited main effects of prenatal smoking on severity of symptoms. Given the number of tests performed, no indication was found for G×E interactions.
Conclusion: Despite the large sample size, no G×E interactions were found. The impact of the DRD4 7-repeat allele might differ, depending on affected status and rater. This finding is discussed in terms of differences in the activity of the dopaminergic system and of different genes involved in rater-specific behaviors.En ligne : http://dx.doi.org/10.1111/j.1469-7610.2008.01998.x Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=606
