时间整合的研究述评

A Review of the Research on Temporal Integration

时间整合是时间上分离的事件或现象被知觉为一个有意义的整体,它是知觉加工的一个重要过程。在物体识别和场景组织研究中发现时间整合的效果受到刺激类型、刺激强度、刺激时距等因素的影响,时间整合的理论解释也不尽相同。近来,在面孔识别研究中也发现分离呈现的面孔部分也能进行整体加工。目前,面孔识别研究中较为关注的两个问题是面孔识别是整体加工还是局部加工?面孔识别是否存在特异脑区?深入开展时间整合的心理机制及其脑机制研究,特别是面孔识别的时间整合的神经机制是很有意义的。

Temporal integration is the combination of temporally separated events or phenomena into a meaningful representation, which is an important process of perception. Many studies found that performance of temporal integration in object and scene perception is affected by some factors, such as stimulating category, stimulating duration. Recently, this process has also been studied in face discrimination. In face perception, the focus of literatures is on two problems： （1） Whether the face recognition is processed holistically or partially？ （2） Whether there is a specific brain zone for face perception. It is of great significance to study the psychological and brain mechanism of temporal integration, especially that in face recognition.
