Figure 2.

Correlation between Alerting Scores and Percent Hits at Baseline, Immediate, and Delay Tests. Alerting scores were significantly correlated with the percent of hits in the immediate and delayedtests for participant receiving 2.0 mA tDCS (solid lines). There was no correlation for participants receiving 0.1 mA tDCS (dotted lines), nor was there a significant correlation for either group between alerting and percent hits during baseline testing. Four data points below 40% are not visible in the baseline figure (top).
