Music Corrects the Brain's "Glitched" Predictions

Key Points:

• A Yale study found that group songwriting and music-making can help people with psychosis, particularly those with schizophrenia and auditory hallucinations, reduce paranoia and reconnect socially by shifting language use from first-person to plural pronouns.
• The research links music’s rhythmic and melodic predictability to the brain’s predictive coding system, suggesting that music therapy may help retrain dysfunctional brain circuits involved in hallucinations and delusions.
• Participants reported feeling more alive and expressive after weekly two-hour songwriting sessions, with no negative side effects typical of antipsychotic medications, highlighting music therapy as a promising complementary treatment.
• The study involved 20 participants over six weeks and showed significant decreases in paranoia among those with less severe hallucinations, along with increased social connectivity and emotional expression.
• Researchers plan to further investigate how consistent music-making may permanently rewire brain circuitry to improve predictive processing in psychosis.
