We examined the moderating effect of dispositional aggressivity on the relationship between alcohol intoxication and aggressive verbalizations. Using a laboratory anger-induction task that simulated an interpersonal conflict as a method to assess aggressive verbalizations (the articulated thoughts in simulated situations paradigm), 70 participants (33 women, 37 men) consumed either an alcoholic or a placebo beverage, and then imagined a series of audiorecorded interpersonal scenarios. Two blind-to-condition raters assessed the frequency of participants' aggressive verbalizations (insults, aggressive threats, belligerent provocations) articulated during anger arousal. Aggressivity was assessed using a standard measure of dispositional aggression. Results supported the aggressivity moderation hypothesis: intoxicated participants high in aggressivity responded with significantly more aggressive verbalizations relative to low-aggressivity participants regardless of beverage condition, and three times more aggressive verbalizations relative to the high-aggressivity/placebo group. There were no gender effects. These data support the hypothesis that alcohol potentiates aggression primarily among individuals at dispositional risk for engaging in such a behavior. Aggr.

我们研究了特质攻击性对酒精中毒与攻击性言语之间关系的调节作用。采用一项模拟人际冲突的实验室愤怒诱导任务作为评估攻击性言语的方法（模拟情境中的清晰思维范式），70名参与者（33名女性，37名男性）饮用了酒精饮料或安慰剂饮料，然后想象一系列录音的人际场景。两名对条件不知情的评分者评估了参与者在愤怒激发过程中表达的攻击性言语（侮辱、攻击性威胁、挑衅）的频率。使用特质攻击性的标准测量方法评估攻击性。结果支持攻击性调节假说：无论饮料条件如何，高攻击性的醉酒参与者相对于低攻击性参与者的攻击性言语明显更多，相对于高攻击性/安慰剂组，攻击性言语多出三倍。不存在性别效应。这些数据支持以下假说：酒精主要在具有此类行为特质风险的个体中增强攻击性。《攻击行为》34:428 - 436，2008年。（c）2008威利 - 利斯公司。
