To examine the relation between social behaviour and vagal activity, the communal behaviour of healthy college men (N = 33) and women (N = 33) was manipulated while monitoring heart rate (HR) and respiratory sinus arrhythmia (RSA). The subjects were classified as low or high on communal trait. Communal behaviour was manipulated by having the subjects behave in an agreeable or quarrelsome manner in scripted role-plays. HR, RSA and self-report arousal were obtained during or immediately following baseline, experimental and relaxation periods. 2 (Gender) x 2 (Communal Trait; low/high) x 2 (Condition; agreeable/quarrelsome) ANCOVAs were performed. Men had lower RSA values when behaving in a quarrelsome fashion than agreeable and lower RSA values than women in the quarrelsome condition. In the latter condition, low communal men reported more arousal than other groups. Strong but opposite associations between RSA and affect arousal were observed in low communal men and woman. Men, especially more quarrelsome (less communal) men exhibited weaker vagal control during arousing social situations.
为了研究社会行为与迷走神经活动之间的关系，在监测心率（HR）和呼吸性窦性心律不齐（RSA）的同时，对33名健康男大学生和33名健康女大学生的社交行为进行了操控。根据共同特质将受试者分为低分组或高分组。通过让受试者在预先编写好的角色扮演中表现出随和或争吵的方式来操控社交行为。在基线期、实验期和放松期期间或之后立即获取心率、呼吸性窦性心律不齐和自我报告的唤醒水平。进行了2（性别）×2（共同特质；低/高）×2（条件；随和/争吵）协方差分析。男性在表现出争吵行为时的呼吸性窦性心律不齐值低于表现出随和行为时，且在争吵条件下的呼吸性窦性心律不齐值低于女性。在后一种条件下，低共同特质的男性报告的唤醒水平高于其他组。在低共同特质的男性和女性中观察到呼吸性窦性心律不齐与情感唤醒之间存在强烈但相反的关联。男性，尤其是更爱争吵（共同特质较低）的男性在引发情绪的社交情境中表现出较弱的迷走神经控制。
