Scores for measures of social cognition (face emotion discrimination, face identity discrimination, face recognition memory, and theory of mind) are given in terms of mean and standard deviation of proportion correct. Scores for measures of social affiliation (social motivation and social support) are given in terms of mean and standard deviation of total scores, where the range of possible scores is given under the name of each measure. Reliability is reported in terms of Cronbach’s alpha, a measure of internal reliability or consistency.
