The effect of acute alcohol intoxication on laboratory-induced aggression among men has been fairly well established. The present study hypothesized that alcohol effects on Point Subtraction Aggression Paradigm (PSAP) responding would not be replicated among "low-risk' college men distinguished by their absence of personality disorder features. Participants were assigned to either Alcohol (n=18), Placebo (n=7), or Time (n=8) comparison groups with each completing 25-min. sessions during the baseline, ascent, peak (70 mg%), and descent (40 mg%) phases of absorption and elimination process. Participants assigned to the Alcohol condition received a .80 ml/kg dose of 95% ethanol mixed with soda in a 1:5 ethanol/soda ratio. As hypothesized, alcohol was associated with stable Point Subtraction Aggression Paradigm responding across the course of absorption, peak, and elimination for all three groups. Aggression Paradigm responding was least variable among the men administered alcohol. The present procedure served to identify a subset of "low-risk" college men whose Point Subtraction Aggression Paradigm responding was not adversely affected by alcohol. The extent to which aggressive personality dispositions contribute to alcohol-induced laboratory aggression remains to be identified. Low-risk college drinkers warrant systematic examination to specify what factors attenuate their reactions to alcohol and other situational provocations.
急性酒精中毒对男性实验室诱导攻击行为的影响已得到相当充分的确立。本研究假设，在以无人格障碍特征为区分的“低风险”大学生男性中，酒精对减法点攻击范式（PSAP）反应的影响不会重现。参与者被分配到酒精组（n = 18）、安慰剂组（n = 7）或时间组（n = 8）进行比较，每组在吸收和消除过程的基线、上升、峰值（70毫克%）和下降（40毫克%）阶段完成25分钟的实验。分配到酒精组的参与者接受了0.80毫升/千克剂量的95%乙醇，与苏打水以1:5的乙醇/苏打比例混合。正如所假设的，在吸收、峰值和消除过程中，酒精与所有三组减法点攻击范式反应的稳定性相关。在接受酒精的男性中，攻击范式反应的变异性最小。本程序用于识别一组“低风险”大学生男性，其减法点攻击范式反应不受酒精的不利影响。攻击性人格倾向在酒精诱导的实验室攻击行为中所起的作用程度仍有待确定。低风险的大学生饮酒者值得进行系统检查，以明确哪些因素减弱了他们对酒精和其他情境挑衅的反应。
