行为、感知和认知是通过不同感觉方式的信息综合而形成的。这种多感官整合通常会带来表现和感知上的好处，反映了来自多个感官的线索提供冗余或互补信息所带来的额外信息。这些线索的空间和时间关系提供了强大的统计信息，这些线索应该如何整合或“绑定”，以创建一个统一的感知表示。最近的许多工作都研究了时间因素，是多感觉处理的组成部分，许多人都集中在多感觉时间绑定窗口的构建-时间的时期内，来自不同的方式的刺激很可能是集成和感知绑定。新出现的证据表明，这一时间窗口是改变了一系列的神经发育障碍，包括自闭症，诵读困难和精神分裂症。除了在感觉处理中的作用外，这些多感觉时间功能的缺陷可能在这些临床疾病的感知和认知弱点中发挥重要作用。在这种情况下，专注于改善多感官颞功能的敏锐度可能有重要的意义，改善“高阶”赤字，作为这些疾病的定义功能。
Behavior, perception and cognition are strongly shaped by the synthesis of information across the different sensory modalities. Such multisensory integration often results in performance and perceptual benefits that reflect the additional information conferred by having cues from multiple senses providing redundant or complementary information. The spatial and temporal relationships of these cues provide powerful statistical information about how these cues should be integrated or “bound” in order to create a unified perceptual representation. Much recent work has examined the temporal factors that are integral in multisensory processing, with many focused on the construct of the multisensory temporal binding window – the epoch of time within which stimuli from different modalities is likely to be integrated and perceptually bound. Emerging evidence suggests that this temporal window is altered in a series of neurodevelopmental disorders, including autism, dyslexia and schizophrenia. In addition to their role in sensory processing, these deficits in multisensory temporal function may play an important role in the perceptual and cognitive weaknesses that characterize these clinical disorders. Within this context, focus on improving the acuity of multisensory temporal function may have important implications for the amelioration of the “higher-order” deficits that serve as the defining features of these disorders.
