Fig. 2: Group Differences in Adaptive Spatial N-Back Training with Concurrent anodal tDCS.

A Group means of participant-level average n-back level for each training day. The p-value represents the interaction effect of condition and session. Error bars represent standard errors. B Group means of participant-level average response times for each training day. The p-value represents the main effect of condition. Error bars represent standard errors. *p < 0.050, #p ≤ 0.070.
