“…The failure of patients with schizophrenia to show a REA would then indicate a left temporal lobe functional deficit or impairment. The findings of Green et al (1994) have later been reproduced in several laboratories (e.g., Conn and Posey, 2000; Hugdahl et al, 2008; Løberg et al, 2004; Rossell and Boundy, 2005). …”

In this article, we have reviewed recent findings from our laboratory, originally presented in Hugdahl et al. (2008). These findings reveal that auditory hallucinations in schizophrenia should best be conceptualized as internally generated speech mis-representations lateralized to the left superior temporal gyrus and sulcus, not cognitively suppressed due to enhanced attention to the ‘voices’ and failure of fronto-parietal executive control functions. An overview of diagnostic questionnaires for scoring of symptoms is presented together with a review of behavioral, structural, and functional MRI data. Functional imaging data have either shown increased or decreased activation depending on whether patients have been presented an external stimulus during scanning. Structural imaging data have shown reduction of grey matter density and volume in the same areas in the temporal lobe. We have proposed a model for the understanding of auditory hallucinations that trace the origin of auditory hallucinations to neuronal abnormality in the speech areas in the left temporal lobe, which is not suppressed by volitional cognitive control processes, due to dysfunctional fronto-parietal executive cortical networks.

“…Meta-analytic evidence shows that psychosis patients with hallucinations do not show this response pattern (Ocklenburg et al, 2013), though again, studies are inconsistent regarding whether this pattern is linked to HEs in the general population (Aase et al, 2018;Conn & Posey, 2000). Similarly, reduced verbal working memory (VWM) is frequently reported in schizophrenia, and may be further impaired in hallucinating patients (Gisselgård et al, 2014).…”

Hallucinatory experiences (HEs) can occur in both clinical and non-clinical groups. However, previous studies of the general population that have investigated cognitive mechanisms underlying HEs have yielded inconsistent results. In this study, we ran a large-scale preregistered multi-site study, in which general population participants (N = 1394, across 11 data collection sites and online) completed assessments of HEs and source memory, dichotic listening, backwards digit span and auditory signal detection tasks, plus a measure of adverse childhood experiences. We found that HEs were associated with performance on the signal detection task and a greater number of reported adverse childhood experiences, but not with any of the other cognitive measures employed. These findings are an important step in improving reproducibility in hallucinations research and suggest that the replicability of some findings regarding cognition in clinical samples need to be investigated.

“…In this task, participants must discriminate conflicting speech stimuli presented simultaneously to both ears; participants typically exhibit a right-ear advantage (Bless et al, 2015). Meta-analytic evidence shows that psychosis patients with hallucinations do not show this response pattern (Ocklenburg et al, 2013), although again, studies are inconsistent regarding whether this pattern is linked to hallucinatory experiences in the general population (Aase et al, 2018; Conn & Posey, 2000).

Correlates of Hallucinatory Experiences in the General Population: An International Multisite Replication Study

Hallucinatory experiences can occur in both clinical and nonclinical groups. However, in previous studies of the general population, investigations of the cognitive mechanisms underlying hallucinatory experiences have yielded inconsistent results. We ran a large-scale preregistered multisite study, in which general-population participants ( N = 1,394 across 11 data-collection sites and online) completed assessments of hallucinatory experiences, a measure of adverse childhood experiences, and four tasks: source memory, dichotic listening, backward digit span, and auditory signal detection. We found that hallucinatory experiences were associated with a higher false-alarm rate on the signal detection task and a greater number of reported adverse childhood experiences but not with any of the other cognitive measures employed. These findings are an important step in improving reproducibility in hallucinations research and suggest that the replicability of some findings regarding cognition in clinical samples needs to be investigated.
