(A) Procedure of CW-Stroop task. The CW-Stroop task was used to measure ability of response inhibition. Chinese characters and symbols of different colors will appear at random on the screen. The subjects are required to press the corresponding keys in accordance with the color that is displayed. The keys that correspond to the colors red, yellow, blue and green are D, F, J and K, respectively. (B) The designs of Experiment 1 and Experiment 2. The study had three groups: tACS, tDCS and sham. Each experiment was divided into three stages (prestimulation, stimulation, and poststimulation).The intervention time for Experiments 1 and 2 was 10 min.
