Nonexperimental field studies have demonstrated an association between alcohol intoxication and self-aggressive behaviors across the spectrum of lethality. Although these results are suggestive, it is not yet known whether alcohol intoxication is causally related to self-aggression. The authors therefore experimentally examined the effects of alcohol intoxication (mean blood alcohol concentration of .10) on a behavioral measure of self-aggression in men (N = 40). After consuming either an alcohol or a placebo drink, participants were provided the opportunity to self-administer shock during a task disguised as a reaction-time game, with self-aggression defined by the intensity of shock chosen. Half of the participants observed a self-aggressive model (a potential moderator of alcohol-related self-aggression). Independent alcohol and model effects were found, with alcohol accounting for over 30% of the self-aggression variance.
非实验性现场研究表明，在整个致死率范围内，酒精中毒与自我攻击行为之间存在关联。尽管这些结果具有启发性，但酒精中毒是否与自我攻击存在因果关系尚不清楚。因此，作者通过实验研究了酒精中毒（平均血液酒精浓度为0.10）对男性自我攻击行为测量指标的影响（N = 40）。在饮用酒精饮料或安慰剂饮料后，参与者有机会在一项伪装成反应时间游戏的任务中自行施加电击，自我攻击行为由所选择的电击强度来定义。一半的参与者观察了一个自我攻击的模型（酒精相关自我攻击的一个潜在调节因素）。研究发现了酒精和模型的独立效应，酒精解释了超过30%的自我攻击行为差异。
