Content analysis of 122 social psychology textbooks confirmed that displaced aggression received a surge of attention immediately following J. Dollard, L. W. Doob, N. E. Miller, O. H. Mowrer, and R. R. Sears (1939), but subsequent interest sharply declined. Contemporary texts give it little attention. By contrast, meta-analysis of the experimental literature confirms that it is a robust effect (mean effect size = +0.54). Additionally, moderator analyses showed that: (a) The more negative the setting in which the participant and target interacted, the greater the magnitude of displaced aggression; (b) in accord with N. E. Millers (1948) stimulus generalization principle, the more similar the provocateur and target, the more displaced aggression; and (c) consistent with the contrast effect (L. Berkowitz & D. A. Knurek, 1969), the intensity of initial provocation is inversely related to the magnitude of displaced aggression.

Meta-analytic procedures were used to assess the degree to which aggression-related cues present in the environment facilitate aggressive responding among negatively aroused subjects. The first study, which examined the so-called weapons effect, the effect of name-mediated cues, and other cue effects, showed clear evidence that aggression cues augment aggressive responses in negatively aroused subjects. This was true for the overall analysis and for name-mediated cues, but confirmation of the weapons effect was restricted to cases wherein subject sophistication and evaluation apprehension were low. A second study used partial correlation analysis to assess independently the effects of seven potential mediators of aggression cue effects. Of these, target-based facilitation and harm capacity of the aggressive response were found to mediate the magnitude of cue-facilitated aggression. A third study showed that these mediators augmented cue effects among neutral as well as negatively aroused subjects. These outcomes are interpreted as emphasizing the role of cognitive factors in the expression of both impulsive and nonimpulsive aggression.

Past research (e.g. Lynch & Haney, 2000) has shown that race plays a significant role in juror decision making in the penalty phase of capital murder trials. This study investigates the possibility of reducing juror bias towards Blacks by altering the content of jury instructions. White and non-White participants received trial information and jury instructions in which the defendants race (Black or White) and the instruction type (standard or simplified) were manipulated. Participants rendered a sentence recommendation, identified factors they considered to be aggravating or mitigating, and responded to instruction comprehension questions. Bias against the Black defendant was significantly reduced when simplified instructions were used and when the defendant was judged by racially diverse jurors. Simplification also led to better comprehension of sentencing instructions. Implications for capital trials are discussed.
