The University of Texas at Dallas, USA For an experimental study of children's responses to peer provocation, this investigation examined the correlations between children's observed behaviours and their self-reports of their emotional experiences, expressions, and social goals provided in an interview immediately following the provocation. Participants were 565 children (approximate ages 8, 10, and 12 years old) who were provoked in two ways in an experimental play session: By losing at a computer game they were playing for a desirable prize, and by being taunted by a peer actor. Children's responses to provocation were reliably coded for verbalisations, facial expressions, and gestures. Results indicated often signi cant but quite modest correlations between children's self-reports of their emotional behaviour and their behaviours as coded during the play session. For the magnitude of these correlations, there were not signi cant developmental differences, and the strength of the correlations did not differ for same-or for other-gender dyads. There was some evidence that for girls, self-reports corresponded to emotional behaviours more strongly than for boys.
