Emotion Recognition Deficits in Schizophrenia

Summary

Individuals living with schizophrenia commonly experience difficulties in identifying and interpreting emotional signals from others, a cornerstone of social cognition. These deficits extend across multiple sensory modalities, most prominently in facial expression recognition but also in vocal prosody and integrated audiovisual cues. Impaired emotion recognition contributes to social withdrawal, reduced functional outcome and heightened caregiver burden. Neurobiological investigations point to disrupted connectivity within fronto-temporal networks, abnormal activation of fusiform and superior temporal regions, and atypical modulation of limbic circuitry. Behavioural evidence suggests that these impairments emerge early in the disorder and may even precede psychotic symptoms, marking them as potential vulnerability markers. Task design—whether involving memory demands, intensity gradations or dynamic versus static stimuli—modulates the observed effect sizes, underscoring the importance of standardised paradigms. Interventions combining cognitive remediation, social skills training and neuromodulation are under evaluation for their capacity to enhance emotion recognition and thus improve overall psychosocial functioning.
