在多种情绪情境下，包括观看图片、听声音以及面临电击威胁时，瞳孔直径会增大。在这项研究中，我们调查了情绪想象过程中瞳孔直径的变化。参与者在瞳孔直径被持续记录的情况下，想象描述愉快、不愉快或中性事件的场景。对瞳孔直径逐秒的变化进行分析，以确定是否以及何时能发现瞳孔根据享乐内容（愉悦或不愉悦程度）而产生的调节。结果表明，在脚本开始后不久，享乐内容就产生了显著影响，与想象中性场景相比，想象情绪性（愉快或不愉快）场景时瞳孔直径增大。想象过程中的瞳孔直径与评定的情绪唤醒度相关联，这与情绪想象过程中瞳孔直径的变化反映交感神经系统活动的解释是一致的。由于情绪想象是临床评估和治疗的一个关键要素，瞳孔直径可能在多种临床相关情境中被证明是情绪投入的一个有用指标。
Pupil diameter is enhanced in a variety of emotional contexts, including viewing pictures, listening to sounds, and during threat of shock. In this study, we investigated pupil diameter changes during emotional imagery. Participants imagined scenes describing pleasant, unpleasant, or neutral events while pupil diameter was continuously recorded. Second by second changes in pupil diameter were analyzed to determine whether and when modulation of the pupil as a function of hedonic content is found. Results indicated a significant effect of hedonic content beginning shortly after script onset, with enhanced pupil diameter when imagining emotional (pleasant or unpleasant), compared to neutral, scenes. Pupil diameter during imagery covaried with rated emotional arousal, consistent with an interpretation that changes in pupil diameter during emotional imagery reflect sympathetic nervous system activity. Because emotional imagery is a key element in clinical assessment and treatment, pupil diameter could prove a useful index of emotional engagement in a variety of clinically pertinent contexts.
