Social cognition was not related to positive and negative symptom severity, but was associated with age and IQ.
CHR individuals demonstrated poorer performance on all measures of social cognition. However, after controlling
for age and IQ, the group differences remained significant for measures of theory of mind and social perception,
but not for facial emotion recognition.
Theory of mind and social perception are impaired in individuals at CHR for psychosis. Age and IQ seem to play an
important role in the arising of deficits in facial affect recognition. Future studies should examine the stability of
social cognition deficits over time and their role, if any, in the development of psychosis.
