Modification of affect perception deficits in schizophrenia

Area of Science:

• Clinical Psychology
• Neuroscience
• Psychiatry

Background:

• Schizophrenia is often associated with deficits in facial affect perception, impacting social functioning.
• Previous interventions have shown mixed results in improving emotion recognition in schizophrenia.

Purpose of the Study:

• To evaluate the efficacy of monetary reinforcement and facial feedback (via mimicry) for enhancing facial affect perception in schizophrenia.
• To assess the generalization of these interventions to facial affect discrimination.

Main Methods:

• Forty inpatients with schizophrenia participated in a study involving a face emotion identification test over four phases: baseline, intervention, immediate post-test, and 1-week follow-up.
• Participants were randomly assigned to one of four groups: repeated practice, monetary reinforcement, facial feedback, or a combination of reinforcement and facial feedback.
• A facial affect discrimination test was used to assess generalization.

Main Results:

• All intervention groups, except for repeated practice, demonstrated significant improvements in facial affect identification.
• These improvements were partially maintained at the 1-week follow-up.
• Limited evidence suggested generalization of the intervention effects to the facial affect discrimination task.

Conclusions:

• Monetary reinforcement and facial feedback interventions show promise for improving facial affect perception in schizophrenia.
• The observed improvements suggest potential for enhancing social cognition in this population.
• Further research is needed to enhance the generalization of these effects to related social-cognitive skills.
