注意在短时距估计中的作用

The Role of Attention in Short Duration Estimation

注意一直是时间知觉研究的一个重要问题。本文综述了研究已经取得一些较为一致的结果:在双任务程序中对时间任务的注意越多,时距估计越准确;在单一任务中对目标刺激的时间属性注意越多,对该刺激的持续时距估计越准确;在时间导向任务中,个体可以有效地、主动把注意导向未来的某段时距,那么将对出现在那个时刻的刺激做出更好的反应。最后,讨论了现有研究中存在的、以及今后研究中需要着重考虑的问题。

Attention is always an important issue in the research of time perception. Some common understandings based on previous studies were summarized ： with the dual-tasks procedure, the more attention to the temporal task was located, the more accurate time estimation would be; with the single task procedure, the more attention to the temporal attribute of the stimulus was located, more accurate the time estimation would be; with the time orientation procedure, if subjects could orient effectively attention to he he he specific future duration, their responses to the stimuli that occurred at that time would be improved. Some problems in current researches and issues deserving more emphasis in future studies were discussed.
