A: The upper graph was visual cognition-reaction time and age. A regression line showed［Reaction Time］＝0.222×e（0.011×［AGE］）, R2: 0.274, mean RT was 0.48 sec±0.17 （standard deviation）. B: The middle graph was auditory cognition-reaction time and age. A regression line showed［Reaction Time］＝0.09×e（0.022×［AGE］）, R2: 0.339, mean RT was 0.44 sec±0.28 （standard deviation）. C: The lower graph was vibratory cognition-reaction time and age. A regression line showed［Reaction Time］＝0.227×e（0.011×［AGE］）, R2: 0.251, mean RT was 0.51 sec±0.20 （standard deviation）. The abscissa represents reaction time in sec, and the ordinate represents age in years, for all graphs.
