Measuring Reciprocity in High Functioning Children and Adolescents with Autism Spectrum Disorders

Few instruments have been developed that measure impairments in reciprocity, a defining feature of autism. We introduce a new test assessing the quality of reciprocal behaviour: the interactive drawing test (IDT). Children and adolescents (n = 49) with and without high functioning autism spectrum disorders (HFASD) were invited to collaborate with an experimenter in making a joint drawing. Within both groups the performance on collaborative reciprocity improved with age. However, compared to the control group, HFASD participants showed less collaborative and more basic reciprocal behaviour and preferred to draw their own objects. They were less tolerant of the experimenter’s input as well. Performance on the IDT was independent of estimated verbal IQ. Reciprocal behaviour in self-initiated objects corresponded with more parental reported autistic traits, while reciprocal behaviour in other-initiated objects corresponded with less autistic traits. The findings of this study suggest that IDT is a promising instrument to assess reciprocity

Peers Influence Prosocial Behavior in Adolescent Males with Autism Spectrum Disorders

Peer influence has a profound impact on decision-making in typically developing adolescents. In this study, we examined to what extent adolescent males (age 11–17 years; N = 144) with and without autism (ASD) were influenced by peer feedback on prosocial behavior, and which factors were related to individual differences in peer feedback sensitivity. In a public goods game, participants made decisions about the allocation of tokens between themselves and their group—in absence or presence of peer feedback. Adolescents with and without ASD were sensitive to peer feedback on prosocial behavior. More autism traits and social interest were associated with less sensitivity to antisocial feedback, suggesting that peer feedback creates opportunities for social adjustment in those with and without ASD.Pathways through Adolescenc
