Abstract

INTRODUCTION: The frequency of auditory hallucinations (AH) is associated with efficiency in inhibiting irrelevant memories, suggesting that the presence of AH may be related to the intrusion of strongly activated representations in memory. Therefore, we hypothesised that the inability to suppress irrelevant memories would be found only in patients currently experiencing AH. METHOD: Performance on a repeated, continuous recognition task was examined in 23 schizophrenia patients with AH present, 20 schizophrenia patients with AH absent, and 24 healthy controls. RESULTS: Patients with current AH made significantly more inappropriate responses (false alarms) to distractors seen on previous runs of the task than nonhallucinating patients. The ability to detect targets (hits) was significantly better in healthy controls than schizophrenia patients, however, there was no significant difference between the two patient subgroups. CONCLUSIONS: The findings confirm that the presence of AH involves a failure to suppress memories that are not relevant to ongoing reality. We propose that a combination of deficits in inhibition and (episodic) memory provides a useful model of AH, which can accommodate many of the characteristic features of the symptom and fits well with the neuroanatomical circuitry that is believed to underlie the occurrence of AH.

  • AVHs likely take multiple forms, with only some forms explicable in terms of misattributed inner speech.

    “A further development has been the recognition that AVHs likely take multiple forms (Jones, 2010), with only some forms of the phenomenon being explicable in terms of misattributed inner speech: others may be better understood in terms of a “hypervigilant” attention to external threat (Dodgson & Gordon, 2009), or intrusions from memory (Michie, Badcock, Waters, & Maybery, 2005).”

  • 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.”

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.
