Abstract. Narrative recall, or describing an event from one’s past, is a common method to study anger in the laboratory. However, most research using this method has not included a neutral speaking control, and therefore the physiological response attributable to emotion versus the act of speech is unknown. We evaluated heart rate, blood pressure, skin conductance level, heart rate variability, and salivary alpha-amylase during silent baseline, neutral speaking, anger recall, and recovery periods, and correlated these measures with trait anger, forgiveness, and rumination ( n = 104). Only systolic blood pressure and skin conductance levels were elevated in the anger recall period above the values in the neutral speaking period, showing the need for this important control. Alpha-amylase was inversely correlated to forgiveness, particularly in females. A neutral speaking control is critical for anger recall protocols because the physiological responses are mostly due to speaking, not anger. Salivary alpha-amylase may be a promising autonomic marker in studies of forgiveness and anger.

对叙述性愤怒回忆的生理反应并与愤怒、宽恕和反刍相关

摘要。叙述回忆，或描述过去的事件，是实验室研究愤怒的常用方法。然而，大多数使用这种方法的研究都没有包括中性说话控制，因此情绪与言语行为的生理反应是未知的。我们评估了沉默基线、中性说话、愤怒回忆和恢复期间的心率、血压、皮肤电导水平、心率变异性和唾液 α-淀粉酶，并将这些测量与特质愤怒、宽恕和反刍（n = 104)。只有收缩压和皮肤电导水平在愤怒回忆期高于中性说话期的值，表明需要这种重要的控制。α-淀粉酶与宽恕成反比，特别是在女性中。中性说话控制对于愤怒回忆协议至关重要，因为生理反应主要是由于说话，而不是愤怒。在宽恕和愤怒的研究中，唾液 α-淀粉酶可能是一个有前途的自主标记。
