| Annotation | Visible speech and gestures can be used by listeners to help them to understand what a speaker means. Previous research has shown that older people are particularly dependent on visible speech, yet seem to profit less than younger people from a speaker's gestures. To understand how visible speech and gestures are used when listening becomes difficult, the authors conducted an experiment with a dichotic shadowing task. The experiment examined how accurately participants could shadow the right- or left-ear input when instructed to attend selectively to a particular ear and whether performance benefited from visual input. Results indicate that older adults' shadowing performance was unaffected by visible speech and gestures. Younger adults did benefit by both visible speech and gestures. Thus, under extremely attention-demanding listening conditions, older people are unable to use a compensatory mechanism for encoding visual language. (RH). |
