Frustration,attribution of blame,and aggression

In contrast to most recent studies of human aggression, multiple measures of naturally occurring aggressive behavior were examined in a realistic and involving setting. Consistent with attributional formulations, it was found that aggression increased in accord with attributions of blame, and that more blame was attributed to another in response to inadequately justified thwartings than to adequately justified thwartings. As anticipated, anger, other-directed attributions of blame, and other-directed aggression were greatest in response to unjustified (illegitimate) thwartings. Justified (legitimate) thwartings produced intermediate anger and intermediate levels of blame and aggression internally and externally. Self-caused (internal) thwartings, ostensibly caused neither by the other's disposition nor by situational factors, produced the least anger and other-directed aggression but the most self-blame/self-aggression. In addition, unexpected thwartings produced independently more anger than did expected thwartings, and high-drive thwartings produced independently less other-directed aggression than did low-drive thwartings. The results are discussed with reference to both the need and the potential for studies of human aggression which employ more ecologically valid settings and measures of aggressive behavior.
