Aging And The Restructuring Of Precued Movements, Paul Amrhein, George Stelmach, Noreen Goggin

Department of Psychology Faculty Scholarship and Creative Works

A precue paradigm was used to examine the time it takes to restructure a planned motor response. Two groups of subjects, a young group, and an elderly group, performed an aiming task in which 75% of the trials involved no change of movement parameters. On remaining trials, subjects had to change one or more of the movement parameters. Elderly subjects had slower reaction times (RTs), movement times, and made more errors in both conditions. Elderly subjects had proportionally longer RTs overall, independent of restructuring a movement plan. Preparation of arm and direction also exhibited a proportional increase in RT. However, …

Age Differences In Bimanual Coordination, Paul Amrhein, George Stelmach, Noreen Goggin

Department of Psychology Faculty Scholarship and Creative Works

A bimanual coordination experiment was conducted in which two groups of 10 male and female participants, elderly (67 to 75 years of age) and young (21 to 25 years of age), produced unimanual, bimanual symmetrical (equal extent amplitude), and bimanual asymmetrical (unequal extent amplitude) movements. In addition to an overall increase in performance latency, the elderly group exhibited a linear increase in response initiation (RT) with increases in task complexity similar to that of the young group. However, the elderly participants showed a proportional increase over the young participants in response execution latency (MT). Further, the elderly group had a …
