Alcohol increases the aggression-augmenting effects of provocation. Theories of alcohol and aggression suggest that impaired cognitive processing induced by acute intoxication leads individuals to process aggression-inducing social cues differently depending on whether they are high or low in salience. We examined the effects of intoxication and aggressive cue salience within the triggered displaced aggression paradigm. An ethnically diverse sample of 74 primarily young adult participants (40 men and 34 women; M=23.28, SD=3.14 years) were recruited from the university community and surrounding area. All participants were provoked by an experimenter, randomly assigned to a 2 (alcohol condition: alcohol vs. placebo) x 2 (trigger salience: high vs. low salience) between-subjects design, and then given the opportunity to aggress against the undeserving triggering agent. As expected, intoxication combined with a salient triggering cue elicited the most displaced aggression among all conditions. These results provide the first evidence that the effect of alcohol on triggered displaced aggression is moderated by the salience of the triggering event.
酒精会增强挑衅引发攻击行为的效应。关于酒精与攻击行为的理论表明，急性中毒引起的认知加工受损会导致个体根据攻击性社会线索的显著程度高低，对其进行不同的处理。我们在触发的替代性攻击范式中研究了中毒和攻击线索显著性的影响。从大学社区及周边地区招募了一个由74名主要为年轻成年人组成的种族多样化样本（40名男性和34名女性；平均年龄M = 23.28岁，标准差SD = 3.14岁）。所有参与者都受到一名实验者的挑衅，被随机分配到一个2（酒精条件：酒精组与安慰剂组）×2（触发显著性：高显著性与低显著性）的组间设计中，然后有机会对不值得的触发者进行攻击。正如预期的那样，中毒与显著的触发线索相结合在所有条件下引发了最多的替代性攻击。这些结果首次证明，酒精对触发的替代性攻击的影响受到触发事件显著性的调节。
