Abstract
This article reviews research on age-related changes in stimulus-response compatibility (SRC) and response precuing effects. These two effects are most directly linked to basic response selection processes, including reaction times. The discussion revolves around several specific aspects of response selection that are harmful for older adults' performance. The effects of aging on the Simon effect, a spatial SRC effect that occurs when stimulus location is irrelevant to a task, is examined. Aging and response selection have important implications designing interfaces with which older adults must interact. Minimizing those harmful aspects of response selection when designing for older adults must be considered.
