碩士 === 國立成功大學 === 心理學系 === 105 === The participants were 24 younger adults aged 20–30 years and 24 older adults aged 61–76 years. The task blocks were choice reaction-time blocks, global stop-signal blocks (with an auditory stop signal), and selective stop-signal blocks (with valid and invalid stop signals). At the same time, 32-channel event-related potential were recorded. Older adults did not exhibit augmented Go RT differences in the choice reaction and 2 stop-signal tasks, but differences in stop-signal RT showed declined reactive control ability among them. Moreover, ERP results revealed that the older adults developed a compensatory mechanism in proactive control to elevate their behavioral results, although the same result was not applied on reactive control.
