Table 2 Comparison of pre-measurements

  1. Table shows results of independent t-tests comparing the pre-measurements for d', RT-Hits (reaction time for Hits), and RT-FA (reaction time for False Alarms). Results show equivalence of pre-measures between the two experimental groups (shamA: sham condition preceding the anodal tDCS, shamC: sham condition preceding the cathodal tDCS) and control group (CG).
