Contextual modulation in high-level vision

点击翻译按钮获取中文摘要

This project aims to understand the nature and mechanisms of spatial contextual modulation and the relationship between spatial and temporal context. Contextual modulation refers to the sometimes profound changes in the appearance of the visual image caused by interactions across space and time. Little work has been done to examine whether spatial context effects exist for high-level attributes of objects, and socially relevant stimuli such as heads and bodies. This project expects to provide new knowledge regarding the way that contextual modulation is mediated by interactions within the normal human visual system. This will provide significant societal benefits as contextual interactions in sensory processing can have profound consequences for our perceptual experience.
