Abstract
Subjects attempted to perform the same manual movement pattern on repeated trials using a visual display of error. Additionally, some subjects heard a tone that was proportional to either the position or velocity of the ideal movement pattern. With the tone, both older and younger adults demonstrated increased anticipation in the form of an increased correlation of their movement pattern with the ideal velocity pattern. However, males exhibited this effect most with the tone that was proportional to ideal velocity, and females, with the tone that was proportional to ideal position. The benefit of the auditory displays did not carry over after they were withdrawn. These results demonstrate one technique for improving perceptual/motor performance. Although older adults exhibited a longer effective time delay, the older and younger adults benefitted from the additional cues to comparable degrees
