The autonomic characteristics of hostility and defensiveness were assessed in 55 male undergraduates based on composite Cook Medley Hostility (Chost) and Marlowe Crowne Social Desirability (MC) scores to create 4 groups: Defensive Hostile (DH; high MC, high Chost), High Hostile (HH; low MC, high Chost), Defensive (Def; high MC, low Chost) and Low Hostile (LH; low MC, low Chost). All subjects engaged in a video game (VG) and hand cold pressor (CP) task. Cardiovascular responses in DH subjects were predicted to show enhanced sympathetic alpha and beta-adrenergic activity and the least vagal control compared to others across tasks. DH and LH men showed significant heart rate reactivity to the CP task compared to HH men. LH men showed significant reductions in high frequency power (vagal assessment) to the tasks compared to HH men. Future studies may employ harassment techniques and include the factors of gender and ethnicity in their assessments.
基于库克梅德利敌意综合量表（Chost）和马洛-克劳恩社会赞许性量表（MC）的得分，对55名男性本科生的敌意和防御性的自主神经特征进行了评估，从而划分出4组：防御性敌意组（DH；高MC，高Chost）、高敌意组（HH；低MC，高Chost）、防御组（Def；高MC，低Chost）和低敌意组（LH；低MC，低Chost）。所有受试者都参与了一项电子游戏（VG）和手部冷加压（CP）任务。预计与其他组相比，DH组受试者在各项任务中的心血管反应会表现出增强的交感α和β肾上腺素能活动以及最低的迷走神经控制。与HH组男性相比，DH组和LH组男性在CP任务中表现出显著的心率反应性。与HH组男性相比，LH组男性在各项任务中的高频功率（迷走神经评估）显著降低。未来的研究可能会采用骚扰技术，并在评估中纳入性别和种族因素。
