We developed a system for measuring reaction times to high-cortical recognition tasks using a personal computer. The following tasks were employed : simple reaction time (SRT), choice reaction time (CRT), visual searching time (VST), memory scanning time (MST) and modified Stroop test (ST). The reaction times to the 5 tasks were measured in 134 normal volunteers who demonstrated full Mini-mental scores. The reaction times to each task showed a significant positive linear correlation with the age of the volunteers ranging from 20 to 69 years old, and were prolonged by approximately 60-80 msec/10 years. The reaction times to 2 of the tasks (SRT and CRT) were significantly shorter than those to the remaining 3 tasks (VST, MST and ST) . These findings indicate that reaction times can be applied to the evaluation of high-cortical recognition functions.
