时间知觉是心理学中的一个重要概念，也称为时间感。它指人在不使用任何计时工具的情况下,对客观现象的延续性和顺序性的感知。这种感知来源于内部或者外部，外部感知可来源于昼夜长短、节气、太阳高度等等。内部感知可来源于我们的心跳、呼吸等等。在实验心理学中，有“复制刺激”的实验。即给被试一个刺激，灯光或是声音，刺激出现的时间不等，被试接受刺激后，以被试所感觉的刺激出现时间复制这个刺激。实验证明，被试在刺激出现3S的情况下复制比较准确。

Time pe****tion is a field of study within psychology and neuroscience that refers to the subjective experience of life: time, which is measured by someone's own pe****tion of the duration of the indefinite and continuous unfolding of events. The perceived time interval between two successive events is referred to as perceived duration. Another person's pe****tion of time cannot be directly experienced or understood, but it can be objectively studied and inferred through a number of scientific experiments. Time pe****tion is a construction of the brain that is manipulable and distortable under certain circumstances. These temporal illusions help to expose the underlying neural mechanisms of time pe****tion.
