Table 1. The comparison of reaction times by performing the attention task in the each group.

	Device group	Sham-device group
Max RT	−1892.00±913.85	2892.79±1873.09	*
Min RT	−1689.85±628.03	112.79±255.77	*

Data=Mean ± SE, *p<0.05 between Device group and Sham device group, Max RT: Maximum Reaction Time, Min RT: Minimum Reaction Time
