Abstract
In 2 experiments, 56 elderly (aged 65–78 yrs) and young Ss (aged 20–28 yrs) performed simple reaction time (RT), choice RT, and movement plan restructuring tasks, using a stimulus precuing paradigm. In Exp 1, the precue display (200 ms) and preparation interval (250, 500, 750, or 1,000 ms) were experimentally determined. In Exp 2, the precue display interval was S determined. For the restructuring task, the precue specified the response on 75% of the trials, enabling movement plan preparation with respect to movement parameters of arm and direction. On remaining trials, the precue incorrectly specified the response, requiring movement plan restructuring. Elderly, but not young, Ss restructured a movement plan for direction more quickly than for arm or for both parameters. These findings indicate that elderly individuals have poorer movement plan maintenance for direction than for arm and thus exhibit functional change in movement preparation processes relative to young individuals.
