Abstract

Models of social preferences explain departures from pure self-interest as a consequence of either outcome-based or intention-based other-regarding motives. Various experimental studies lend support to the conclusion that subjects behave as if they conditioned their behaviour on the perceived intentions of others. We present a new experiment that explores this as if clause by making the ability to detect intentions a treatment variable. We compare normally developing children with autistic children – typically unable to perceive intentions – and find differences consistent with the hypothesis that behaviour responds to intentions, especially if unkind.
