Note: 22q11DS, 22q11.2 deletion syndrome; PERT, Pennsylvania Emotion Recognition Test Total Number of Correct Emotions Identified; WCST Persev., Wisconsin Card Sorting Test Perseverative Error Standard Score; Word Reading, WIAT-II Word Reading Standard Score. Coefficients from mixed model regressions are presented. Intercept is the test score at hypothetical Age 0 as fitted by the regression. Age indicates the change in test score with age. Age2 is the rate of change of test score with age.
