Tested the hypothesis that reactive aggression (RA) but not proactive aggression (PA) should be associated with heightened attention to rejection, ridicule, and failure cues. In addition to a reaction time measure of selective attention, participants also completed a vignette-based interview regarding their interpretation of ambiguous social situations, and children, parents, and teachers completed questionnaire measures of child aggression and related variables. Consistent with predictions, RA but not PA was related to biased attention for rejection, ridicule, and failure cues. However, contrary to expectation, heightened RA scores were associated with suppressed rather than enhanced attention to such cues. Despite the unexpected direction of this attentional bias, as predicted it was significantly related to the well-established tendency of aggressive children to interpret ambiguous social situations as threatening, which was also uniquely related to RA. Further, the correlation between suppressed attention and RA was fully mediated by interpretation bias.
