摘　　要：关于急性应激对攻击行为的影响,现有研究多集中于单次急性应激情境下。然而,相比单次急性应激,对重复暴露于同一应激源的研究更能反映人们在现实生活中经历的应激事件。与单次应激不同,重复性急性应激与应激适应有关,能够节省资源,具有很强的进化和适应意义,但目前关于重复性急性应激对攻击行为的影响却知之甚少。鉴于此,研究运用事件电位相关技术、鼻喷催产素和催产素受体基因型分析方法,探讨重复性急性应激对攻击行为的影响及内部机制,并进一步探讨通过内部和外部调控重复性急性应激反应后攻击行为的变化。In the context of the effect of acute stress on aggressive behavior,most studies on stress responses involve exposing participants to novel,one-time stressors;however,people are constantly exposed to similar stressors in everyday life multiple times.Compared with the response to one-time exposure to stressors,the ability to adapt to repeated stress has greater evolutionary utility as it preserves resources by relieving the response to non-life-threatening stress;however,little is known about the effect of repeated acute stress on aggressive behavior.This study comprised six experiments.Participants completed a modified version of the Trier Social Stress Test for Groups(TSST-G),Taylor Aggression Paradigm(TAP),dot-probe task,and the Single-Target Implicit Association tests(ST-IAT).The event-related potential(ERP)technique,intranasal oxytocin(IN-OT),genotyping of the oxytocin receptor(OXTR),and single nucleotide polymorphisms(SNP)analysis were performed to explore the influence mechanism of repeated acute stress on aggressive behavior and to further investigate the change in aggressive behavior after regulation of repeated acute stress through internal and external channels.
