a z-scores for individual tests and composite z-scores. Composite z-score (online) is the mean of four z-scores: spatial span backward maximum length, digit span backward maximum length, online letter n-back accuracy, and online spatial n-back accuracy. Composite z-score (offline) is the mean of three z-scores: offline letter n-back accuracy, offline spatial n-back accuracy, and BTA raw score. Composite z-score (full battery) is the mean of five z-scores: spatial span backward maximum length, digit span backward maximum length, letter n-back accuracy (mean of online and offline percentages), spatial n-back accuracy (mean of online and offline percentages), and BTA raw score (*p < 0.05, **p < 0.01, ***p < 0.001). b Backward spatial span, backward digit span, and Brief Test of Attention task results. Error bars indicate standard deviations. (*p < .05). c N-back accuracy. Percentage correct for online spatial n-back, online letter n-back, offline spatial n-back, and offline letter n-back. Error bars indicate standard deviations. d Individual differences in full-battery composite z-scores (vs. sham) for left anodal and right anodal stimulation. Mean composite z-scores (full battery) were −0.25 (SD 0.71) for sham stimulation, 0.13 (SD 0.82) for left anodal stimulation, and 0.11 (SD 0.81) for right anodal stimulation
