Cross-modality matching of linguistic prosody in older and younger adults

چکیده
Older adults perform worse than younger adults in recognising auditory linguistic prosody. Such problems may result from deterioration at the sensory level (e.g., hearing loss). The current study used a novel approach to examine this, by determining older adult’s performance on a visual prosody task. If older adults are able to process visual prosody this suggests that any difficulty they show when processing auditory linguistic expressions could be related to hearing loss. The current study presented 18 younger and 11 older adults with pairs of sentences spoken by the same talker. They decided whether the pair contained the same or different prosody in a simple AX matching task. Sentence pairs were presented in four different ways; auditory-auditory (AA), visual-visual (VV), audio-visual (AV), and visual-audio (VA). Compared to older adults, younger adults exhibited similar performance for focused statements but showed better performance for questions. We suggest that problems processing questioning expressions might result from hearing loss, problems perceiving pitch, or problems at the cognitive level.

Perception of Linguistic and Affective Prosody in Younger and Older Adults
Previous research has suggested that older adults display deficits in affective-prosodic processing, while grammaticalprosodic processing remains intact. In the present study, groups of younger and older adults took part in a series of experiments assessing their comprehension of prosodic information at the affective, grammatical and perceptual levels. It was found that older and younger adults...
متن کاملCross-modality matching of linguistic and emotional prosody
Talkers can express different meanings or emotions without changing what is said by changing how it is said (by using both auditory and/or visual speech cues). Typically, cue strength differs between the auditory and visual channels: linguistic prosody (expression) is clearest in audition; emotional prosody is clearest visually. We investigated how well perceivers can match auditory and visual ...
متن کاملFirst-Encounter Talks between Younger and Older Adults in Taiwan: A Conversation Analysis Approach
Outside of Western contexts, natural-conversation-based research on intergenerational communication is relatively rare. To help redress this imbalance, this paper explores the conversational styles of first-encounter talks between five pairs of college students and older adults in Taiwan, and infers the interactional norms that underlie them. It is found that younger Taiwanese adults tend to ex...

متن کاملEffect of Different Cognitive Loads on Gait Stability in Younger and Older Adults
Purpose: As many older people fall during dual tasks, we aimed to examine the effect of different cognitive loads on learning gait stability in younger and older adults. Methods: 10 younger (Mean±SD age: 25.91±3.42 years) and 10 older adults (Mean±SD: 66.65±4.28 years) were healthy volunteers without a history of falls. They were asked to do three tasks on a treadmill with cognitive load (none...
