Abstract：
Subjective estimates of duration are affected by emotional expectations about the future. For example, temporal intervals preceding a threatening event such as an electric shock are estimated as longer than intervals preceding a non-threatening event. However, it has not been unequivocally shown that such temporal overestimation occurs also when anticipating a similarly arousing but appealing event. In this study, we examined how anticipation of visual erotic material influenced perceived duration. Participants did a temporal bisection task, where they estimated durations of visual cues relative to previously learned short and long standard durations. The color of the to-be-timed visual cue signalled either a chance of seeing a preferred erotic picture at the end of the interval or certainty of seeing a neutral grey bar instead. The results showed that anticipating an appealing event increased the likelihood of estimating the cue duration as long as compared to the anticipation of a grey bar. Further analyses showed that this temporal overestimation effect was stronger for those who rated the anticipated erotic pictures as more sexually arousing. The results thus indicate that anticipation of appealing events has a similar dilating effect on perceived duration as does the anticipation of aversive events.
摘要：
对持续时间的主观估计受到对未来的情绪期望的影响。例如,例如电击的威胁事件之前的时间间隔被估计为比非威胁事件之前的间隔更长。然而,还没有明确表明，在预期类似的唤醒但吸引人的事件时，也会发生这种暂时的高估。在这项研究中,我们研究了对视觉色情材料的预期如何影响感知的持续时间。参与者做了时间平分任务，他们估计视觉线索的持续时间相对于以前学习的短和长标准持续时间。要定时的视觉提示的颜色表明，有可能在间隔结束时看到首选的色情图片，或者肯定会看到中性灰色条。结果表明，与灰色条的预期相比，预期有吸引力的事件增加了估计提示持续时间的可能性。进一步的分析表明，对于那些将预期的色情图片评为更多的性唤起的人来说，这种时间上的高估效果更强。因此，结果表明，对吸引人的事件的预期对感知的持续时间具有与对厌恶事件的预期相似的扩张效应。
