Semantic organization of hallucinated "voices" in schizophrenia
Roy E. Hoffman, Elizabeth Oates, R. Julian Hafner, Harry Hustig, Thomas H. McGlashan · American Journal of Psychiatry · 1994
The authors found that the different hallucinated "voices" of four schizophrenic subjects reported over 1-3 weeks expressed semantic content that was at least as persistent as clauses sampled from single 5-7-minute conversational discourses of four comparison speakers. The high degree of semantic recurrence of voices from one day to the next may contribute to the mistaken belief that these experiences derive from a particular nonself agent or speaker.
