Schizophrenia Research Under the Framework of Predictive Coding: Body, Language, and Others

Area of Science:

• Neuroscience
• Cognitive Psychology
• Psychiatry

Background:

• Predictive coding offers a robust framework for schizophrenia research.
• Therapeutic applications of predictive coding in schizophrenia are currently underdeveloped.

Purpose of the Study:

• To establish a comprehensive, operationalist, and model-oriented understanding of schizophrenia.
• To bridge the gap between predictive coding theory and clinical practice in schizophrenia.

Main Methods:

• Systematic review of predictive coding models across key domains relevant to schizophrenia.
• Linking established models to specific clinical impairments and manifestations.
• Development of a research roadmap for therapeutic intervention.

Main Results:

• Predictive coding models were examined across embodiment, prior weighting, time processing, language, self-other differentiation, and social interaction.
• Each model was explicitly connected to observable clinical deficits in schizophrenia.
• A structured roadmap for future research and intervention development was proposed.

Conclusions:

• A unified, model-based understanding of schizophrenia through predictive coding is feasible.
• The framework provides a basis for developing targeted, novel therapeutic strategies.
• Further research is warranted to translate these models into effective clinical interventions.
