Fig. 3: Group Differences in Spatial N-Back Performance Following Stimulation.

A Mean difference in d’ from pre-training to post-training, split by condition and n-back level. B Mean difference in d’ from pre-training across all sessions, split by condition and n-back level. C Mean difference in response time from pre-training to post-training, split by condition and n-back level. D Mean difference in response time from pre-training across all sessions, split by condition and n-back level. Error bars represent standard error. *p < 0.050, **p < 0.005.
