***p <.001. 95% CI for Mean Difference = 95% Confidence Interval for Mean Difference. As there are four face options for every trial, ¼ (or.25) is the comparison (chance) value against which response rates are compared. DANVA-2 Adult Face Accuracy, percentage of facial emotions correctly identified on the Diagnostic Analysis of Nonverbal Accuracy–Second Edition adult subtest; DANVA-2 Child Face Accuracy, percentage of facial emotions correctly identified on the Diagnostic Analysis of Nonverbal Accuracy–Second Edition child subtest.
