Fig. 1: Relationship between the RSD of CRA and the performance of CRA.

A Relationship between RSD and ACC; b Relationship between RSD and RT. Note. In Fig. 1a, the dots indicate the average ACC in each trial for the three groups. In (B), the dots indicate the RT for each trial. Shadows indicate standard errors. ACC accuracy on compound remote association task, RT reaction time on compound remote association task, RSD relative semantic distance, L+R− anodal stimulation of F7 and cathodal stimulation of F8, L−R+ cathodal stimulation of F7 and anodal stimulation of F8; SHAM sham control for tDCS.
