“…However, Jagacinski, Greenberg, Liao, and Wang (1993) and Jagacinski, Liao, and Fayyad (1995) demonstrated that in a manual tracking task, older adults were able to benefit from similarly formatted supplementary auditory cues regarding the target to be followed. In a study of discrete tracking involving only younger adults, McGee and Christ (1971) similarly found that redundant auditory displays providing information about the target did improve performance. The pattern of results across these experiments suggests that supplementary auditory information is more likely to be helpful for manual control tasks with simple dynamics if it is redundant with regard to the target toward which the performer must act rather than redundant with regard to the performer's own responses.…”

In a stationary target acquisition task, both 65-year-old and 20-year-old adults exhibited a negatively accelerated curvilinear relationship between the spatial variability of submovement endpoints and average submovement velocity. For high velocities, the variability was greater for the older adults. This elevated motor noise is considered a primary cause of their slower performance. Both age groups also exhibited a linear relationship between submovement duration and the logarithm of submovement relative accuracy. A stochastic model indicates that the two age groups were similar in the strategies they used to compose single movements from a variety of submovements. However, when performing sequences of movements containing varied target distances, older adults exhibited a repetition effect whereas younger adults exhibited a contrast effect. Older adults may plan movements individually, whereas younger adults plan sequences.

“…In previous research, supplementary auditory displays have been found to improve perceptual-motor performance over levels achieved with visual displays alone (e.g., Benepe, Narasimhan, & Ellson, 1954, cited in Poulton, 1974Janiga & Mayne, 1977;McGee & Christ, 1971;Mirchandani, 1972;Pitkin & Vinje, 1973). However, supplementary auditory displays are sometimes ineffective (e.g., Cote, Williges, & Williges, 1981;Lionvale, 1979, cited in Keele, 1977Noble & Noble, 1972).…”

Ss performed the same M-shaped manual movement pattern on repeated trials using a visual display of instantaneous error. With practice, Ss' effective time delays were diminished by increased anticipation as evidenced by an increased correlation of their movement patterns with the input velocity. However, younger adults had lower error scores, performed larger movements, and had shorter effective time delays than did older adults. Supplementary auditory displays additionally contributed to greater anticipation. However, men exhibited this effect most with an auditory display of input velocity and women with an auditory display of input position. This benefit of the auditory displays did not carry over after these displays were withdrawn. When the visual display was additionally withdrawn, benefits of the auditory training were manifest among the older adults as relatively greater temporal modulation of movement.
