Are neurocognition and facial emotion recognition related in schizophrenia?

Abstract

IntroductionPatients with schizophrenia (SCZ) show impairments in many social cognition domains including facial emotion recognition (FER). The existence of a relationship association between FER and neurcognitive functioning (NF) remains uncertain.ObjectivesTo investigate the association between ToM functioning and neurocognitive functioning in SCZ.MethodsFER was evaluated in 58 patients with stable schizophrenia with a newly validated FER task constructed from photographs of the face of a famous Tunisian actress representing the Ekman's six basic emotions. They also completed a neurocognitive battery comprising the following tests: the Hopkins Verbal Learning Test–Revised (HVLT-R), the Letter Digit Substitution Test (LDST), the Stroop Test (ST), the “Double Barrage” of Zazzo (DBZ), the Modified Card Sorting Test (MCST), Verbal Fluency (VF), the Trail Making Test-Part A (TMT-A) and the Digit Span (DS).ResultsPatients who performed better in the FER task had better performance in the VF task (P = 0.001) and in the immediate recall of the HVLT-R (P = 0.021). No correlations were found with the other neurocognitive tests.ConclusionsOur results suggest that FER represents an autonomous cognitive function which does not necessarily require good NF.Disclosure of interestThe authors have not supplied their declaration of competing interest.
