Inhibition in schizophrenia: association with auditory hallucinations

Waters, F·2003·Schizophrenia Research

Abstract

The study investigated whether auditory hallucinations (AH) in schizophrenia are linked to a deficit in inhibition. Two tasks assessing the intentional suppression of cognitive events-the Hayling Sentence Completion Test (HSCT) [Neuropsychologia 34 (1996) 263] and the Inhibition of Currently Irrelevant Memories Task (ICIM) [Nature Neuroscience 2 (1999) 677]-were administered to 42 patients with schizophrenia and 24 normal controls. Presence and severity of symptoms in the patient group were examined using the Positive and Negative Syndrome Scale (PANSS). Patients performed significantly worse on the measures of inhibition compared to controls. More importantly, among patients, significant positive correlations were obtained between an index of AH severity (defined as an increase in frequency of AH on PANSS) and the number of type A errors on the HSCT and errors in the last three runs of the ICIM. An increase in AH severity was, therefore, associated with increasingly impaired control of intentional inhibition. Furthermore, no significant correlations were found between these indices of inhibition and either negative, general or positive symptoms (excluding AH scores).

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Hallucination frequency in schizophrenia is associated with difficulties on tasks requiring suppression of irrelevant and distracting information, pointing to deficits in intentional inhibition.

    “In support, studies have showed that hallucination frequency in SCZ was associated with difficulties on tasks requiring the suppression of irrelevant information and distracting information, like the ICIM and HSCT tasks, 98,99 a Directed Forgetting (DF) task, 100 and the Dichotic Listening task, 101 all pointing to deficits in intentional inhibition.”
  • People reporting hallucinatory experiences make more false alarm responses on an inhibitory control task than non-hallucinating participants.

    “Separately, a number of studies have shown that people reporting hallucinatory experiences make more false alarm responses on an inhibitory control task (ie, fail to suppress irrelevant stimuli) than non-hallucinating participants. 20-22”

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.
