` Any theory of perception must tackle the fundamental problem of how the mind binds together sensory information into a coherent reality. Although a great deal is known about binding of visual features across space, much less is known about binding stimuli from different modalities across time. Different sensory systems encode inputs with different latencies, giving rise to a temporal "window of integration" within which multisensory stimuli may be perceived as unitary. Various factors are known to widen or narrow this window. In the present work, we focus on the factor of attention--a factor which can dramatically shorten the time required for a sensory signal to impact consciousness. The central question of this proposal is how attention may influence the duration of the integration window.

` 任何知觉理论都必须解决这样一个基本问题，即心智如何将感官信息结合在一起，形成一个连贯的现实。虽然我们对视觉特征在空间上的结合有很多了解，但对来自不同模态的刺激在时间上的结合知之甚少。不同的感觉系统以不同的延迟对输入进行编码，从而产生一个时间“整合窗口”，在该窗口内多感觉刺激可能被感知为单一的。已知有各种因素会扩大或缩小这一窗口。 在目前的工作中，我们专注于注意力的因素-一个可以显着缩短感官信号影响意识所需时间的因素。 这项建议的核心问题是注意力如何影响一体化窗口期的长短。
