Verification of motor and cognitive load in DTI can show the cognitive or motor impact separately on the DT to consist the coping strategies for the daily performances. Computerized 3 experiments of cognitive (CT), motor (MT) and dual tasks (DT) were randomly tested in participants. All participants (n=46) were educated to press the button 1 (BT1) during preparing period. In CT, participants should release the BT1 as fast as possible if congruent letters in meaning and color of letter (Go), or they should press the BT1 consistently if incongruent. In MT, participants should release the BT1 and then tap the BT2 10 times as fast as possible if intuitive “○” was presented (Go), or press the BT1 consistently if “X” was presented. In DT, the Go trials of MT were changed with those of CT. The reaction time (RT) of correct releases of BT1 in all tasks, the button shifting time between BT1 release and BT2 press, and finger tapping rate in MT and DT were also measured. Then the ratio of RT of CR in CT and MT over DT were calculated to represent the DTI. The ratio of RT of CR in CT (78.6±13.0%, P
