| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Previous studies demonstrated that elderly individuals show disadvantage with in a stimulus-response (S-R) compatibility task. For instance, the boxes and arrows on a computer monitor indicate responses: the arrows indicate which hand, left or right, and the boxes indicate which finger to use left or right. In some cases, performance of elderly individuals were comparable to those of young adults, while brain activities of elderly individuals were higher than those of young adults. It is still unclear whether elderly individuals perform as good as young adults do, when responses are to perform by feet. In addition, we have no information whether elderly individuals show disadvantage in a choice reaction task in which two response sets, which are the sets of actions that the participants may have to perform. The purpose of this study was to examine this R-R mapping effect in elderly and young adults. The stimuli consisted of colors (red/green) and shapes (◯/△). The colors of the stimuli corresponded to the position (left/right) of the button to press. The shapes of the stimuli corresponded to the hand/foot to perform (left/right hand/foot). The behavioral data and brain activities with a near-infrared spectoroscotopy (NIRS) were analyzed. The elderly showed the compatibility effect for reaction times. The NIRS scores in front-dorsolateral area were greater in elderly individuals, especially when the incompatible combination of the two-dimensional responses was required. However, substantial difference between hands and feet was not observed in two age groups, suggesting general declines in frontal area in elderly individuals. | |
