Lipreading in Adults

Did you know that researchers have studied the integration of auditory and visual information for speech perception in older as well as younger adults, including lipreading? The results shows that on average older adults are as successful as young adults at integrating auditory and visual information for speech perception at the syllable level. There were differences in the response alternatives chosen, however. When auditory and visual integration of speech information failed to occur, producing a nonfused response, participants selectws an alternative response from the modality with the least ambiguous signal. For example, young adults with normal peripheral sensitivity often chose an auditory alternative whereas, older adults and control participants leaned toward visual alternatives. In additions, older adults demonstrated poorer lipreading performance than their younger counterparts.
