Contextual modulation in high-level vision

本项目旨在了解空间语境调节的本质和机制，以及空间和时间语境之间的关系。语境调制是指由于空间和时间的相互作用而引起的视觉图像外观的深刻变化。很少有人研究空间背景效应是否存在于物体的高级属性和社会相关刺激（如头部和身体）中。该项目希望提供关于正常人类视觉系统内相互作用介导的上下文调制方式的新知识。这将提供显著的社会效益，因为感觉处理中的上下文交互可以对我们的感知体验产生深远的影响。

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.
