Aggressive Boys' Hostile Perceptual and Response Biases: The Role of Attention and Impulsivity

Abstract

The present study addressed whether (1) aggressive boys show hostile biases or general deficits in social perception, (2) aggressive boys' social perceptual difficulties also characterize isolate and isolate-aggressive children, (3) aggressive, isolate, and isolate-aggressive boys' social perceptual difficulties are attributable to inattention and impulsivity, and (4) aggressive and nonaggressive boys differ in the links between social perception and proposed behavioral responses. Aggressive boys demonstrated hostile biases, but not general deficits, in intention-cue detection relative to average-status boys. Isolate-aggressive boys resembled aggressive boys in social perception, whereas isolate boys showed mild deficits relative to average-status boys. Although isolates' general deficits were predominantly accounted for by inattention and impulsivity, aggressives' and isolate-aggressives' hostile biases remained after these problems were statistically controlled. The aggressive groups proposed aggressive responses much more frequently than the nonaggressive groups following intentions perceived as nonhostile. Measures corresponding to several stages of Dodge's social information processing model discriminated the aggressive from nonaggressive groups, thus providing support for this model.
