Background: Psychosis involves a distortion of thought content, which is partly reflected in anomalous ways in which words are semantically connected into utterances in speech. We sought to explore how these linguistic anomalies are realized through putative circuit-level abnormalities in the brain's semantic network.

Methods: Using a computational large-language model, Bidirectional Encoder Representations from Transformers (BERT), we quantified the contextual expectedness of a given word sequence (perplexity) across 180 samples obtained from descriptions of 3 pictures by patients with first-episode schizophrenia (FES) and controls matched for age, parental social status, and sex, scanned with 7 T ultra-high field functional magnetic resonance imaging (fMRI).

Language in interaction: turn-taking patterns in conversations involving individuals with schizophrenia.

Psychiatry Res

September 2024

Psychiatric Unit, Department of Medicine and Surgery, University of Parma, Parma, Italy; Department of Mental Health, Local Health Service, Parma, Italy.

Article Synopsis
  • Individuals with schizophrenia face challenges in communication, particularly in managing conversations compared to control subjects.
  • A study analyzed dialogues between individuals with schizophrenia and medical doctors, revealing distinct turn-taking patterns, such as increased overlap and mutual silence during interactions.
  • These patterns indicate that communication dynamics in schizophrenia are unique, with mutual silence linked to the severity of negative symptoms, but not to their subjective experiences.
