Results display β coefficients (β) with SE, z score, original p value, and corrected p value (p’) for the following predictors: frequency (5, 10, 20, and 40 Hz and sham), switch condition (trials in which switch = risk minus trials in which repeat = risk), and valence (gain minus loss trials). All predictors were modeled with random effects.
