本研究的目的是研究听觉情绪刺激期间和之后瞳孔大小的变化。30名受试者（15名女性和15名男性）在听10种消极和10种积极的高度唤起的声音（如婴儿的哭声和笑声）和10种情绪中性的声音（如常规的办公室噪音）时测量瞳孔反应。受试者还对与刺激相关的主观体验进行了评分。结果表明，在情绪负性刺激和情绪正性刺激下，瞳孔的大小均显著大于中性刺激。刺激抵消后2 s的结果表明，负刺激和正刺激后的瞳孔尺寸均显著大于中性刺激。这些结果表明，自主神经系统对高度兴奋的情绪刺激很敏感。主观评分证实了刺激对受试者情绪体验的影响正如预期的那样。进一步的分析表明，只有在中性刺激和听觉刺激时，女性受试者的瞳孔反应才明显大于男性。综上所述，我们的研究结果表明，系统选择的刺激显著影响了被试的生理反应和主观体验。例如，在情感计算中，使用瞳孔大小变化作为计算机输入信号是可能的。听觉情绪相关线索也可以用来调节用户的情绪反应。2003爱思唯尔科学有限公司版权所有。
The present objective was to investigate pupil size variation during and after auditory emotional stimulation. Thirty subjects' (15 females and 15 males) pupil responses were measured while listening to 10 negative and 10 positive highly arousing sounds (e.g. a baby crying and laughing), and 10 emotionally neutral sounds (e.g. regular office noise). The subjects also rated their subjective experiences related to the stimuli. The results showed that the pupil size was significantly larger during both emotionally negative and positive stimuli than during neutral stimuli. The results for the time period of 2 s following the stimulus offset showed that pupil size was significantly larger after both negative and positive than neutral stimulation. These results suggest that the autonomic nervous system is sensitive to highly arousing emotional stimulation. The subjective ratings confirmed that the stimuli influenced the subjects' emotional experiences as expected. Further analyses showed that female subjects had significantly larger pupil responses than males only to neutral stimuli and only during the auditory stimulation. In sum, our results showed that systematically chosen stimuli significantly affected the subjects' physiological reactions and subjective experiences. It could be possible to use pupil size variation as a computer input signal, for example, in affective computing. Auditory emotion-related cues could also be utilized to modulate the user's emotional reactions. (C) 2003 Elsevier Science Ltd. All rights reserved.
