Yet, few studies have directly assessed the value people with an ASD place on social interactions, or how rewarding they report it to be. In the present study, we directly measure social motivation by looking at responses to a questionnaire assessing self-reported pleasure in social and non social situations. Twenty-nine adolescents with ASD and matched controls took part in the study. Our results reveal that children with an ASD differ from the controls with respect to social enjoyment, but not with respect to physical and other sources of hedonism. Further analyses demonstrate that the degree of social anhedonia correlates with autism severity.

When Prototypes Are Not Best: Judgments Made by Children with Autism / Catherine J. MOLESWORTH in Journal of Autism and Developmental Disorders, 38-9 (October 2008)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 38-9 (October 2008) . - p.1721-1730 Titre : When Prototypes Are Not Best: Judgments Made by Children with Autism Type de document : Texte imprimé et/ou numérique Auteurs : Catherine J. MOLESWORTH, Auteur ; Dermot M. BOWLER, Auteur ; James A. HAMPTON, Auteur Année de publication : 2008 Article en page(s) : p.1721-1730 Langues : Anglais (eng) Mots-clés : Autism Asperger-syndrome Categorization Concepts Heterogeneity Prototype Index. décimale : PER Périodiques Résumé : The current study used a factorial comparison experimental design to investigate conflicting findings on prototype effects shown by children with autism (Klinger and Dawson, Dev Psychopathol 13:111–124, 2001; Molesworth et al., J Child Psychol Psychiatry 46:661–672, 2005). The aim was to see whether children with high-functioning autism could demonstrate prototype effects via categorization responses and whether failure to do so was related to difficulty understanding ambiguous task demands. Two thirds of the autism group did show an effect. The remainder, a sub-group defined by performance on a control task, did not. The discussion focuses on the influence of heterogeneity within the autism group and the ability to resolve ambiguity on task performance. Finally, an alternative experimental design is recommended for further research into these issues.
