How the brain integrates information from different sensory modalities to form coherent perceptions of the external environment is a challenging question in sensory and cognitive neuroscience. Neurophysiologically, sensory interactions have become well documented over the last decade or so. Complementary perceptual research, however, is lacking. This project seeks to redress the imbalance, using audio-visual interactions as a paradigm. Psychophysical experiments will explore: (i) audio-visual interactions in perception (sound enhancing vision, vision enhancing hearing); (ii) audio-visual interactions in spatial attention. Neurophysiological evidence, plus very recent psychophysical findings of audio-visual interactions, suggest this will be a rich vein of research.

大脑如何整合来自不同感觉模式的信息以形成对外部环境的连贯感知是感觉和认知神经科学中的一个具有挑战性的问题。在过去十年左右的时间里，神经生理学上的感觉相互作用已经得到了很好的记录。然而，互补的知觉研究是缺乏的。这个项目试图纠正这种不平衡，使用视听互动作为范例。心理物理实验将探索：(i)感知中的视听相互作用（声音增强视觉，视觉增强听觉）；（ii）空间注意力的视听互动。神经生理学的证据，加上最近关于视听互动的心理物理学发现，表明这将是一个丰富的研究脉络。
