Nonverbal behavior and the elderly Flashcards
key point
there is considerable variability in the encoding and decoding of nonverbal behavior among the elderly
changes in paralanguage
- increased pitch for males
- increase in jitter (varying pitch of voice, produces rough sound) and shimmer (varying loudness of voice; produces a shaky quality)
- decreased speech rate
- increased dysfluency (e.g. hesitations, speech errors, etc) comparable to that of elementary school children (return to child-like patterns of behavior)
- d2l
encoding to the elderly by others
- young adults speak to elderly with high vocal intensity and high pitch, especially if they have minimal contact with elderly people
- people speak more slowly to elderly than young adults (smartest)
decoding of elderly peoples speech
- people can make gross judgments about a speakers age from his/her voice
- negative stereotypes are often associated with voices of the elderly
- the more slowly a person speaks, the older they are judged to be
elderly decoding of paralanguage
- hearing problems, especially fast speech and background noises
- can improve with ehanced intonation
- elderly people do not perform as well as young adults on decoding emotion in the voice, even when controlling for hearing loss, working memory, and cognitive decline
encoding of facial expression
- malatesta and izard (1987) studied elderly women and found that they showed more masking and blends
- sagging of facial muscles (slow sign vehicles) gave impression of permanent emotional state.
decoding elderly facial expression
- hard for untrained observers to accurately decode elderly facial expressions
- observers see sadness with elderly report anger
- people are best at decoding age-matched peers
decoding elderly facial expression of emotion
- young (20-39), middle (40-59) old (60-81) healthy adults were asked to pose facial expressions
- a panel of young, middle, and older raters had to judge which expression was being posed
- accuracy in judging expressions was lowest when encoder was an older adult
- d2l*
elderly decoding of facial expressions
- elderly (60-80) perform sig. worse than younger adults (20-40) on decoding facial expressions of emotion
- they perform as well when decoding emotion from the voice
- elderly with Alzheimers have more problems decoding facial expressions of emotion than healthy or psychiatric outpatient elderly
- peak performance in the ability to identify facial exp. of emotion is in middle age, children and older adults perform worst
- fear, sadness, anger, happiness, were hardest for the elderly to decode
- West et al (2012) d2l*
elderly gaze at facial expressions of emotion (2012)
- older adults looked less freq. and shorter periods of time at angry and somewhat longer at happy faces, than younger adults
- d2l*
brain activation for decoding age matched peers (d2l)
-brain activation is highest when elderly and young decode faces of other elderly or young faces; with the exception of angry faces
elderly decoding facial expression and health outcomes
- facial expressions of physical therapists
- esp smiles
- pos. associated with improvements over time in:
- mobility
- performing activities of daily living
- decrease in confusion
- facial expressiveness conveys empathy
elderly encoding space
- dyads interacting in public are closest for young children and old people and farthest for middle aged (1972)
- dyads in shopping mall: closest distance in preschool and senior citizen pairs (1983)
- when approaching a friend, elderly W (63-85) use personal space, young women (19-24) use intimate space (1981)
- between age 56-94, older age is associated with a preference for closer space except among those with limited mobility who prefer more space (2003)
- d2l
possible reasons for decrease in space
- sensory problems
- social isolation
- dependency
decoding of space by elderly
- elderly females perform better on tasks when they can sit close to another person-opposite for college students
- elderly females find closeness enjoyable
- people tolerate closeness more when being invaded by someone of the same age (1974)
