Object chaining, a speech pattern, is more common in individuals with schizophrenia and thought disorder. This phenomenon correlates with less comprehensible speech, aiding in the identification of thought disorder.

Area of Science:

  • Psychiatry
  • Linguistics
  • Cognitive Science

Background:

  • Thought disorder is a key symptom in schizophrenia, affecting communication.
  • Object chaining is a linguistic phenomenon observed in speech.

Purpose of the Study:

  • To investigate the relationship between object chaining and thought disorder in schizophrenia.
  • To determine if object chaining is a reliable indicator of thought disorder.

Main Methods:

  • Analysis of speech samples from individuals with schizophrenia (with and without thought disorder) and healthy controls.
  • Utilizing the object-subject ratio (OSR) to quantify object chaining.

Main Results:

  • Thought-disordered schizophrenic subjects exhibited higher OSRs compared to non-thought-disordered subjects and controls.

  • Object chaining was found to correlate negatively with speech predictability.

    • Conclusions:

    • Object chaining is significantly associated with thought disorder in schizophrenia.
    • Increased object chaining contributes to reduced speech comprehensibility, a marker for thought disorder.
