Abstract:

Because working memory and perception are primary cognitive constructs in human information processing system, elaborating interactions between the two is scientifically important to reveal the nature of human information processing. Working memory and perception are commonly believed to interact with each other on several levels. One important aspect of such interactions is the functional impact of working memory contents on visual perception. The present article reviews existing literature on the modulation of visual perception by working memory contents. It is concluded that the contents of working memory can guide perceptual selection, enhance perceptual sensitivity and alter perceptual experience. And it is suggested that the underlying mechanism of such memory effects on perception may be the top-down modulation during working memory maintenance.

Key words: working memory, perceptual selection, perceptual sensitivity, perceptual experience
