为了研究忧虑的心理生理相关性，作者记录了健康男性在基线、放松、忧虑诱导和即兴演讲任务预期期间的心率、呼吸性窦性心律失常 (RSA)、皮肤电导水平和 α 脑电图不对称性。与基线、放松和预期相比，担忧与较高的心率和较低的 RSA 相关。担忧的进一步特征是皮肤电导水平高于基线，但低于预期水平。最后，与预期相比，担忧与左额叶活动相对较大有关。特质公开演讲焦虑与担忧期间的左额叶活动呈正相关。这些结果支持这样的观点：担忧是一种独特的情绪状态，不同于恐惧的预期。
To study the psychophysiological correlates of worrying, the authors recorded heart rate, respiratory sinus arrhythmia (RSA), skin conductance level, and alpha electroencephalographic asymmetry in healthy males during baseline, relaxation, worry induction, and anticipation of an impromptu speech task. Compared with baseline, relaxation, and anticipation, worrying was associated with greater heart rate and lower RSA. Worrying was further characterized by higher skin conductance levels compared with baseline but lower levels than during anticipation. Finally, worrying was associated with relatively greater left frontal activity compared with anticipation. Trait public speaking anxiety was positively correlated with left frontal activity during worrying. These results support the notion that worrying is a unique emotional state that is different from fearful anticipation.
