Age and Temporal Processing of Audiovisual Speech

描述（由申请人提供）：拟议的研究将检查时间处理在老年人和年轻人的视听语音整合中的作用。随着年龄的增长，感觉和认知的变化可能会降低老年人的时间处理。如果言语的时变方面对于多模态整合是突出的，那么老年人相对于年轻人来说，在协调感觉间信息方面应该受到损害。实验将测试感知速度的重要性和视听语音检测的方式的时间一致性。这项研究对多模态感知，语音的时间处理，随着年龄的变化和整个生命周期的沟通感觉和认知变化有影响。

DESCRIPTION (provided by applicant): The proposed research will examine the role of temporal processing in audiovisual speech integration for older and younger adults. Sensory and cognitive changes with age may degrade temporal processing in older adults. If time varying aspects of speech are salient to multimodal integration, then older adults should be impaired relative to younger adults for the coordination of intersensory information. Experiments will test the importance of perceptual speed and the temporal congruity of the modalities for detection of audiovisual speech. This research has implications for multimodal perception, temporal processing of speech, sensory and cognitive changes with age and communication across lifespan.
