Statistical Analysis
EXG
We performed per protocol analyses using linear random effects models for each outcome measure. We performed the Shapiro-Wilk test to assess whether the data were normally distributed. The Eriksen flanker test (ie, accuracy rate and response time [RT]) and ERP (ie, N2, P3b amplitudes) data were analyzed using repeated-measures ANOVA to determine group (EXG vs AEG) × time (pre- vs postintervention) interactions. We also used the paired
