Abstract

The Integrated self-categorization model of autism (ISCA) argues that a self-categorization dysfunction could be the link between some of the disparate features of ASD. To the extent that this is true, any social psychological phenomena arising from self-categorization should be impaired in autistic people. Based on this premise, we investigated whether ingroup favouritism within the minimal group paradigm is reduced to the extent that individuals possess autistic traits. Results indicated that participants with a high proportion of autistic traits showed less ingroup favouritism, and that this was due to a decreased tendency for self-categorization. By providing evidence of the disruption of self-categorization in ASD, these findings lend support to ISCA and raise important issues for existing accounts of the disorder.
