Piloerection is known as an indicator of strong emotional experiences. However, little is known about the physiological and emotional specificity of this psychophysiological response. In the presented study, piloerection was elicited by audio stimuli taken from music and film episodes. The physiological response accompanying the incidence of piloerection was recorded with respect to electrodermal, cardiovascular and respiratory measures and compared to a matched control condition. The employment of an optical recording system allowed for a direct and objective assessment of visible piloerection. The occurrence of piloerection was primarily accompanied by an increase of phasic electrodermal activity and increased respiration depth as compared to a matched control condition. This physiological response pattern is discussed in the context of dominant theories of human piloerection. Consideration of all available evidence suggests that emotional piloerection represents a valuable indicator of the state of being moved or touched.
立毛反应是强烈情绪体验的一个指标。然而，对于这种心理生理反应的生理和情绪特异性，人们知之甚少。在本研究中，通过音乐和电影片段的音频刺激引发立毛反应。记录伴随立毛反应发生的生理反应，涉及皮肤电、心血管和呼吸测量，并与匹配的对照条件进行比较。采用光学记录系统可以直接和客观地评估可见的立毛反应。与匹配的对照条件相比，立毛反应的发生主要伴随着阵发性皮肤电活动的增加和呼吸深度的增加。这种生理反应模式是在人类立毛反应的主导理论背景下讨论的。考虑到所有可用的证据，情绪性立毛反应是一个有价值的指标，可以反映被感动或触动的状态。
