Summary

Monetary reinforcement and facial feedback strategies improved facial affect perception in schizophrenia patients. These improvements in recognizing emotions showed some lasting effects but did not significantly generalize to discrimination tasks.

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.
