This study examined the elevated heart rate (HR) response to alcohol intoxication, thought to reflect an increased sensitivity to alcohol-induced reward, as a potential factor in the increased likelihood of alcohol-induced aggression.
Three groups, intoxicated high (n=37) and low (n=37) HR responders and sober controls (n=73), participated in a laboratory measure of physical aggression, the Taylor Aggression Paradigm.
Results revealed that intoxicated high HR responders were more aggressive than the intoxicated low HR responders and sober controls.
These findings are interpreted within a hypothetical model relating increased alcohol-induced aggression to a dysregulation in the motivational system responding to rewards.
本研究考察了对酒精中毒时心率（HR）升高的反应，这种反应被认为反映了对酒精诱导奖励的敏感性增加，是酒精诱导攻击行为可能性增加的一个潜在因素。
三组人员，即高心率（n = 37）和低心率（n = 37）的醉酒反应者以及清醒对照组（n = 73），参与了一项身体攻击行为的实验室测量，即泰勒攻击范式。
结果显示，高心率的醉酒反应者比低心率的醉酒反应者和清醒对照组更具攻击性。
这些发现是在一个假设模型中进行解释的，该模型将酒精诱导的攻击行为增加与对奖励做出反应的动机系统失调联系起来。
