时距知觉的扭曲:新异刺激效应

时距知觉会受到刺激新异性的影响,新异刺激的呈现时间往往被认为长于等时距重复出现的标准刺激的呈现时间.已有研究在解释这种主观的时距扩张现象时主要涉及三种假设:注意假设、唤醒假设和神经编码效能假设.研究中的变量混淆问题、跨通道效应和时间因素是今后研究中值得思考的几个问题.对于新异刺激效应产生的心理和神经机制,研究者们还存在着较大分歧.进一步探讨其心理和神经机制对理解时距知觉具有重要意义.

Distortions of Time Perception: The Oddball Effect

Duration perception can be affected by the oddness of stimuli. An oddball stimulus will be judged to have lasted longer than others of equal physical duration in a repeated series. It has been suggested that there are three main hypotheses to explain the subjective expansion of duration: attention hypothesis, arousal hypothesis and the neural coding efficiency hypothesis. The issues, such as variable confusion, the cross-modal effects and the time factors, are worth considering for future studies. Furthermore, no agreements are reached on the psychological and neural mechanisms of the subjective expansion of duration, and further explorations to these problems are of great significance to understand duration perception.
