The affective startle modulation task has been an important measure in understanding physiological aspects of emotion and motivational responses. Research utilizing this method has relied primarily on a 'passive' viewing paradigm, which stands in contrast to everyday life where much of emotion and motivation involves some active choice or agency. The present study investigated the role of choice on the physiology of emotion. Eighty-four participants were randomized into 'choice' (n=44) or 'no-choice' (n=40) groups distinguished by the ability to choose between stimuli. EMG eye blink responses were recorded in both anticipation and stimulus viewing. Results indicated a significant attenuation of the startle magnitude in choice condition trials (relative to no-choice) across all picture categories and probe times. We interpret these findings as an indication that the act of choice may decrease one's defensive response, or conversely, lacking choice may heighten the defensive response. Implications for future research are discussed.
情感性惊跳调制任务一直是理解情绪和动机反应生理方面的重要手段。利用这种方法的研究主要依赖于一种“被动”的观察范式，这与日常生活形成鲜明对比，在日常生活中，情绪和动机很大程度上涉及到某种主动选择或能动性。本研究探讨了选择对情绪生理学的作用。84 名参与者被随机分为“选择”（n=44）或“无选择”（n=40）组，其区别在于是否能够在刺激之间进行选择。在预期和刺激观看过程中都记录了肌电图眨眼反应。结果表明，在所有图片类别和探测时间中，选择条件试验中的惊跳幅度（相对于无选择条件）显著降低。我们将这些发现解释为选择行为可能会降低防御反应的迹象，或者相反，缺乏选择可能会增强防御反应。讨论了对未来研究的影响。
