^aSignificant effects are indicated by boldface. Performance on working memory and inhibitory control tasks was measured by counting number of errors; a lower score indicates a better performance. *SES, socioeconomic status; B, between-subjects; W, within-subjects. Bold values correspond to significant predictors.
