Note. CON: n=13 for psychopathology and n=72 for neurocognition

^aPairwise Comparisons (Bonferroni): p<.05

^bWelch ANOVA with Tamhane Pairwise Correction for Unequal Variances used when homogeneity non-significant.

^cFirst effect size reports difference between all three groups/second effect size reports contrast for SCZ vs. PMD.
