In the present study, 119 high school boys and 79 institutionalized de
linquent boys of the same age range were assessed on their own aggress
ive behavior and on their tendencies to attribute social failure to co
ntrollable, external, stable causes, anticipate a hostile affective re
sponse, and endorse aggressive behavioral responses to hypothetical so
cial situations. While the two populations of boys did not differ dete
ctably in their attributional tendencies, the relations between an ind
ividual's aggressiveness and an individual's attributions differed con
siderably across the two populations. In particular, among delinquent
but not among nondelinquent boys, the tendency to attribute one's soci
al failures to stable and controllable causes predicted stronger hosti
le emotional responses to failure and a tendency to endorse physically
aggressive responses following such failure. These hostile emotional
responses to failure and this preference for a physically aggressive r
esponse, in turn, predicted greater actual aggression within the popul
ation of delinquent boys. Neither of these links could be demonstrated
for nondelinquent boys. However, in the nondelinquent sample, attribu
ting social failure to external and controllable causes predicted endo
rsement of aggressive responses only indirectly through increased host
ile affect. It was concluded that the specific relations between cogni
tive and affective responses to social failure may be a contributing f
actor to the serious physical aggression displayed by some delinquents
and to the less serious aggression of nondelinquents. (C) 1993 Wiley-
