This study examined the relationship of sensitivities of Gray's behavioral inhibition system (BIS) and behavioral approach system (BAS) to cardiac autonomic stress responses during laboratory tasks among 65 healthy men (n=34) and women (n=31) aged 22-37 years. Carver and White's BIS-BAS scales were used to measure BIS and BAS sensitivities. We measured heart rate (HR), respiratory sinus arrhythmia, and preejection period during mental arithmetic, a reaction time task, and a speech task. Results revealed that BAS sensitivity was related to HR reactivity and parasympathetic withdrawal during the tasks, but was unrelated to baseline levels. BIS sensitivity was unrelated to both reactivity and baseline levels of all measures. Overall, our results suggest that the relationship of the BAS with cardiac reactivity seems to be mediated by the parasympathetic nervous system.
本研究调查了65名年龄在22至37岁之间的健康男性（n = 34）和女性（n = 31）在实验室任务期间，格雷行为抑制系统（BIS）和行为趋近系统（BAS）的敏感性与心脏自主应激反应之间的关系。采用卡弗和怀特的BIS - BAS量表来测量BIS和BAS的敏感性。我们在进行心算、反应时间任务和言语任务时测量了心率（HR）、呼吸性窦性心律不齐和射血前期。结果显示，BAS敏感性与任务期间的HR反应性和副交感神经撤离有关，但与基线水平无关。BIS敏感性与所有测量指标的反应性和基线水平均无关。总体而言，我们的结果表明，BAS与心脏反应性之间的关系似乎是由副交感神经系统介导的。
