RESUMO
INTRODUCTION: Although considered a promising design for testing social cognition, it is not clear to what extent the EmoBio test of emotion recognition actually predicts community functioning. It is also not clear whether the test measures something unique or different from nonsocial cognition. The present study tests whether EmoBio accounts for GAF function score and two operationalised community outcome measures. The study also analyses cognitive predictors of EmoBio performance, testing whether stimulus modality affects prediction. METHODS: Eighty-three patients with schizophrenia were tested with EmoBio, the cognitive battery MCCB and WAIS-IV. RESULTS: EmoBio accounted for a significant portion of variance in all three outcome measures. Only EmoBio predicted Lifetime Relationship status, and EmoBio remained a significant predictor of Independent living beyond non-social cognition. All cognitive measures contributed significantly to the variance in EmoBio, but entered together explained only a third of total variance. CONCLUSION: The study shows that emotion recognition accounts for community outcome. There was no clear effect of test-modality in predicting EmoBio performance, indicating no method invariance problem with EmoBio. It also indicates that the mechanisms underlying impaired social cognition in schizophrenia are different from the hypothesised non-verbal learning deficits in the disorder.

Are people with superior intelligence also superior in interpreting the emotions of others? Some studies find that an underlying g-factor links all mental processes leading to an expectation of a positive answer to the question, while other studies find that there is a cost to giftedness. No previous study have tested social cognition among highly gifted, or the Mensa society specifically. The study measures emotion recognition in 63 members of the Norwegian Mensa and 101 community controls. The Mensa group had a higher total score on the EmoBio test and was specifically better at differentiating the anger emotion, otherwise hypothesized to be mediated by subcortical processes. There was no difference in heterogeneity between the groups, contrary to the expectation of an autistic subgroup in Mensa. The study indicate that the positive manifold extends also to social cognition, and runs counter to the concept of a cost to giftedness.
RESUMO
Schizophrenia is associated with an increased violence risk, particularly homicide. One possible, but scarcely explored, contributor to the increased violence risk is social cognitive impairment. Individuals with schizophrenia show impairments in social cognition that are associated with poor functional outcome. This study examined social cognition among homicide offenders with schizophrenia (HOS), applying validated measures of emotion perception and theory of mind (ToM). Two groups of individuals with schizophrenia were compared, one had committed homicide (HOS, nâ¯=â¯26), and the other had no violence history (non-HOS, nâ¯=â¯28). Healthy controls (HC, nâ¯=â¯71) were included as reference group for one measure. Emotion perception was indexed by the Emotion in Biological Motion (Emotion) and Pictures of Facial Affect (PFA) tests. ToM was assessed with the Hinting Task and Movie for the Assessment of Social Cognition (MASC). The results showed that HOS participants had significantly poorer performance than non-HOS in both emotion perception and ToM. For the MASC test, HOS participants showed large deficits compared to HC (-4 standard deviations). Particularly, HOS participants made a substantial number of undermentalizing errors. The results suggest that emotion perception deficits and a tendency to undermentalize may be important for understanding homicide in schizophrenia.
