Multitasking performance
To assess alterations in multitasking performance, we first analyzed perceptual discrimination during multitasking via an rm-ANOVA with three time points (baseline, 1-week, 1-month) and the between-subjects factor of tACS group (theta, control). Results revealed a significant main effect of time (FPerformance on each outcome measure at the baseline, 1-week, and 1-month follow ups.Multitasking (MT) values represent the difficulty threshold achieved during Monitor. Sustained Attention are the composite RT score for both sustained attention modules in ACE. Working Memory is the composite span score on the forwards and backwards spatial span tasks. The bottom three rows display RCS values on exploratory analyses on ACE-X tasks. Values in parentheses below the means represent standard deviation. Values in bold font indicate a significant change from baseline in a group × time interaction (p
