This study examined changes in time perception as a function of depressive symptoms, assessed for each participant with the Beck Depression Inventory (BDI). The participants performed a temporal bisection task in which they had to categorize a signal duration of between 400 and 1600 ms as either as short or long. The data showed that the bisection function was shifted toward the right, and that the point of subjective equality was higher in the depressive than in the non-depressive participants. Furthermore, the higher the depression score was, the shorter the signal duration was judged to be. In contrast, the sensitivity to time was similar in these two groups of participants. These results thus indicate that the probe durations were underestimated by the depressive participants. The sadness scores assessed by the Brief Mood Inventory Scale (BMIS) also suggest that the emotional state of sadness in the depressive participants goes some way to explaining their temporal performance. Statistical analyses and modeling of data support the idea according to which these results may be explained by a slowing down of the internal clock in the depressive participants.
本研究考察了时间知觉随抑郁症状的变化情况，使用贝克抑郁量表（BDI）对每位参与者的抑郁症状进行评估。参与者执行了一项时间二分任务，在该任务中，他们必须将400至1600毫秒之间的信号持续时间归类为短或长。数据显示，二分函数向右偏移，且抑郁参与者的主观相等点高于非抑郁参与者。此外，抑郁得分越高，信号持续时间被判断为越短。相比之下，这两组参与者对时间的敏感度相似。因此，这些结果表明抑郁参与者低估了探测持续时间。通过简短情绪量表（BMIS）评估的悲伤得分也表明，抑郁参与者的悲伤情绪状态在一定程度上解释了他们的时间表现。数据的统计分析和建模支持了这样一种观点，即这些结果可能是由于抑郁参与者的内部时钟变慢所致。
