The association between punishment and cooperation in children with high-functioning autism

This study examined judgment about punishment and whether punishment promoted cooperation in the prisoner's dilemma game (PDG) in children with high-functioning autism (HFA) and typically developing (TD) children. In total, 66 6- to 12-year-olds participated in this study. Children were first asked about judgments regarding rewards and punishment in stories, and then they were asked to play the PDG with a partner in conditions with and without punishment. Results showed that children with HFA believed that hitting others should deserve punishment to a greater extent than TD children did. It indicated that children with HFA understood that bad acts should be punished, suggesting that these children have already acquired the general concept of “punishment.” Children displayed higher levels of cooperation in the condition with punishment than in the condition without punishment in the PDG, suggesting that punishment promoted cooperation in the PDG in both children with HFA and TD children.
