This article presents the first systematic test of the attention-allocation model for alcohol-related aggression. According to this model, alcohol has a "myopic" effect on attentional capacity that presumably facilitates aggression by focusing attention on more salient provocative, rather than less salient inhibitory, cues in hostile situations. Aggression was assessed using a laboratory task in which mild electric shocks were received from, and administered to, a fictitious opponent. Study 1 demonstrated that a moderate-load cognitive distractor suppressed aggression in intoxicated subjects (to levels even lower than those exhibited by a placebo control group). Study 2 assessed how varying the magnitude of a distracting cognitive load affected aggression in the alcohol and placebo conditions. Results indicated that the moderate-load distraction used in Study 1 (i.e., holding four elements in sequential order in working memory) suppressed aggression best. Cognitive loads of larger and smaller magnitudes were not successful in attenuating aggression.
本文首次对酒精相关攻击行为的注意力分配模型进行了系统测试。根据该模型,酒精对注意力容量具有“近视”效应,大概是通过在敌对情境中将注意力集中在更显著的挑衅性线索而非不太显著的抑制性线索上,从而促进攻击行为。使用一项实验室任务评估攻击行为,在该任务中,被试会从一个虚构对手那里接受并向其施加轻度电击。研究1表明,中等负荷的认知干扰物会抑制醉酒受试者的攻击行为(降至甚至低于安慰剂对照组所表现出的水平)。研究2评估了改变干扰性认知负荷的大小如何影响酒精组和安慰剂组的攻击行为。结果表明,研究1中使用的中等负荷干扰(即在工作记忆中按顺序记住四个元素)对攻击行为的抑制效果最佳。更大和更小幅度的认知负荷在减轻攻击行为方面均未成功。
