Abstract

Background: The neurocognitive basis of auditory verbal hallucinations is unclear. Aims: To investigate whether people with a history of such hallucinations would misattribute their own speech as external and show differential activation in brain areas implicated in hallucinations compared with people without such hallucinations. Method: Participants underwent functional magnetic resonance imaging (fMRI) while listening to pre-recorded words. The source (self/non-self) and acoustic quality (undistorted/distorted) were varied across trials. Participants indicated whether the speech they heard was their own or that of another person. Twenty people with schizophrenia (auditory verbal hallucinations n =10, no hallucinations n =10) and healthy controls ( n =11) were tested. Results: The hallucinator group made more external misattributions and showed altered activation in the superior temporal gyrus and anterior cingulate compared with both other groups. Conclusions: The misidentification of self-generated speech in patients with auditory verbal hallucinations is associated with functional abnormalities in the anterior cingulate and left temporal cortex. This may be related to impairment in the explicit evaluation of ambiguous auditory verbal stimuli.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
