显然，饮酒会促进攻击性互动的升级过程。研究了醉酒、清醒和混合二人组的互动模式。成对的男大学生（30 名）被随机分配到这些条件下。接受酒精治疗的受试者接受了 0.964 克无水酒精/公斤体重。在反应时间竞赛的每次试验开始时，如果对手在试验中速度较慢，二人组中的每个成员都会选择他希望对手收到的电击级别。每个成员都会通过反馈灯得知对手为他选择的电击级别。显然，醉酒的两人比清醒的两人选择了更高的休克水平。混合二人组倾向于选择比醉酒二人组更低的休克水平，但比清醒二人组选择更高的休克水平。这些差异没有统计学意义。在 6 次试验的第一组中，醉酒的二人组的攻击性升级，而清醒或混合的二人组都没有表现出这种升级。对这些发现的一种解释是，酒精引起的认知障碍干扰了受试者评估其行为后果和解释对手行为的能力。第二种解释是，由于与饮酒相关的预期效应，醉酒的情侣不会感到被迫采取非攻击性的立场。讨论了二元互动范式在酒精相关暴力研究中的价值。
Evidently, alcohol ingestion facilitates escalatory processes in aggressive interactions. Interaction patterns were examined in intoxicated, sober and mixed dyads. Pairs of male college students (30) were randomly assigned to these conditions. Subjects who received alcohol received 0.964 g of absolute alcohol/kg of body weight. At the beginning of each trial in a reaction-time competition, each member of the dyad selected the shock level that he wanted his opponent to receive if the opponent was slower on the trial. Each member was informed by feedback lights of the shock level that his opponent had selected for him. Evidently, the intoxicated dyads selected higher shock levels than did the sober dyads. Mixed dyads tended to select lower shock levels than intoxicated dyads, but higher shock levels than sober dyads. These differences were not statistically significant. Intoxicated dyads escalated in aggression over the 1st block of 6 trials, whereas neither sober nor mixed dyads evidenced such an escalation. One interpretation of these findings is that the cognitive disruption caused by the alcohol interfered with the subjects'' ability to evaluate the consequences of their behavior and to interpret the behavior of their opponents. A 2nd interpretation is that, because of the expectancy effects associated with alcohol consumption, intoxicated dyads did not feel constrained to a nonaggressive stance. The value of the dyadic-interaction paradigm in the study of alcohol-related violence was discussed.
