Substantial empirical evidence supports low resting heart rate (HR) as the best replicated psychophysiological correlate of aggression [Ortiz and Raine, 2004]; however, researchers continue to debate the explanatory mechanisms of the phenomenon. Sensation seeking has been proposed as a possible outcome of low resting HR that may lead to aggressive tendencies but findings have been inconsistent in terms of showing a relationship between sensation seeking and aggression. A meta-analysis was conducted on 43 independent effect sizes, from studies with a total of 32,217 participants, to test the hypothesis that sensation seeking would be positively related to aggression across studies. A significant overall effect size was found (d = .1935, P<.001), supporting the hypothesis. Moderator analyses revealed that the relationship differed based on participant and methodological characteristics, such as participant age and the nature of the aggression measurement; however, these conclusions are limited by the uneven number of studies in many of the moderator classes. Overall, the findings provide support for higher levels of aggression in high sensation seekers and have theoretical implications for arousal theory. Further research on the links between arousal, sensation seeking and aggression can inform clinicians about potential interventions.
大量的实证证据支持低静息心率（HR）是攻击性最强的可重复心理生理学相关性[Ortiz 和 Raine，2004]；然而，研究人员仍在争论该现象的解释机制。感觉寻求被认为是低静息 HR 的可能结果，可能导致攻击性倾向，但在感觉寻求与攻击性之间存在关系方面，研究结果并不一致。对 43 个独立的效应量进行了荟萃分析，这些效应量来自共有 32217 名参与者的 43 项独立研究，以检验感觉寻求与攻击性之间存在跨研究正相关的假设。发现了一个显著的总体效应量（d =.1935，P<.001），支持了这一假设。调节分析表明，这种关系因参与者和方法学特征的不同而不同，例如参与者的年龄和攻击性测量的性质；然而，这些结论受到许多调节类别的研究数量不均的限制。总的来说，这些发现支持高感觉寻求者具有更高水平的攻击性，这对唤醒理论具有理论意义。进一步研究唤醒、感觉寻求和攻击性之间的联系，可以为临床医生提供有关潜在干预措施的信息。
