The aim of the present study was to examine the effects of emotional state on time perception in patients with depression and to investigate if time perception in patients with depression could be changed by induced emotional state.
A clinically-depressed (CD, n=19) and non-depressed (ND, n=22) group viewed four video clips of different levels of valence and arousal (ie, positive-high arousal, positive-low arousal, negative-high arousal, negative-low arousal). After inducing emotion state, all participants performed a time perception task to measure differences in the perception of time.
The results showed that the CD group perceived time passing more slowly than the ND group at baseline and in all conditions, especially in the negative-low arousal condition. The ND group perceived time passed more quickly in the positive-high arousal condition compared to the CD group. These results indicate that emotional state with combined valence and arousal factors could change time perception in patients with depression.
Based on these results, it is suggested that changing the emotional state of the depressive patient by considering valence as well as arousal is important to improve the distortion on time perception.
本研究旨在探讨情绪状态对抑郁症患者时间感知的影响，并研究诱导情绪状态是否能改变抑郁症患者的时间感知。
一个临床抑郁症（CD，n = 19）组和一个非抑郁症（ND，n = 22）组观看了四个不同效价和唤醒水平的视频片段（即积极 - 高唤醒、积极 - 低唤醒、消极 - 高唤醒、消极 - 低唤醒）。在诱导情绪状态后，所有参与者进行了一项时间感知任务，以测量时间感知的差异。
结果显示，在基线和所有条件下，CD组比ND组感觉时间过得更慢，尤其是在消极 - 低唤醒条件下。与CD组相比，ND组在积极 - 高唤醒条件下感觉时间过得更快。这些结果表明，效价和唤醒因素相结合的情绪状态可以改变抑郁症患者的时间感知。
基于这些结果，建议通过考虑效价和唤醒水平来改变抑郁症患者的情绪状态，对于改善时间感知的扭曲很重要。
