The Effect Of Age-Related Declines In Inhibitory Control On Audiovisual Speech Intelligibility, Avanti Dey

All Theses and Dissertations (ETDs)

Audiovisual: AV) speech perception is perception in which both auditory and visual information is available in order to understand a talker, compared to an auditory signal alone, during face-to-face communication. This form of communication yields significantly higher word recognition performance as compared to either sensory modality alone, constituting a general AV advantage for speech perception. Despite an overall AV advantage, older adults seem to receive less benefit from this bimodal presentation than do younger adults. However, there is evidence to suggest that not all age-related deficits in AV speech perception are of a sensory nature, but are also influenced by …
