Notes: Scores for the Eyes Test represent difference in % correct. Scores for all other measures represent z-scored differences from norms. Mean difference scores are adjusted for covariates of age, sex, and IQ. Means are presented for primary components of each task unless significant interactions were detected. Significant differences appear in blue.
