Low resting heart rate is a well-replicated biological correlate of aggression, and sensation seeking is frequently cited as the underlying causal explanation. However, little empirical evidence supports this mediating relationship. Furthermore, the biosocial model of violence and social push theory suggest sensation seeking may moderate the relationship between heart rate and aggression. In a sample of 128 college students (82.0% White; 73.4% female), the current study tested a moderation model as an alternative relationship between resting heart rate and sensation seeking in regard to aggression. Overall, the findings partially supported an interaction effect, whereby the relationship between heart rate and aggression was moderated by sensation seeking. Specifically, the oft-noted relationship between low resting heart rate and increased aggression was found, but only for individuals with low levels of sensation seeking. If replication supports this finding, the results may better inform prevention and intervention work.
静息心率低是攻击性的一个被充分证实的生物学相关因素，而感觉寻求通常被认为是其潜在的因果解释。然而，很少有实证证据支持这种中介关系。此外，暴力的生物社会模型和社会推动理论表明，感觉寻求可能会调节心率与攻击性之间的关系。在一项由 128 名大学生（82.0%为白人；73.4%为女性）组成的样本中，本研究测试了一个调节模型，作为心率与感觉寻求对攻击性之间关系的替代关系。总的来说，研究结果部分支持了一个交互效应，即心率与攻击性之间的关系被感觉寻求所调节。具体来说，发现了静息心率低与攻击性增加之间的关系，但仅适用于感觉寻求水平较低的个体。如果这一发现得到证实，结果可能会更好地为预防和干预工作提供信息。
