N2 - Patients with Schizophrenia and current auditory hallucinations exhibit a combination of deficits in context binding and intentional inhibition. Hallucinations also occur in the general population suggesting an underlying continuity of causal mechanisms, however, these experiences may also differ (e.g., in frequency), indicating some differences in aetiology. The aim of this study was to examine the frequency of hallucinatory experiences in healthy young adults and to assess whether difficulties in context binding characterize individuals highly predisposed to hallucinations. A modified version of the Launay-Slade hallucination scale-revised, including an assessment of the frequency of hallucination experiences, was completed by 615 undergraduates from which sub-samples of high (n = 25) and low (n = 27) scorers were drawn. Context memory ability was assessed using a voice-location binding task. The results showed that the frequency of hallucinations in high LSHS-R scorers was much less than that previously reported for individuals with schizophrenia. Furthermore, no group differences in context memory binding were observed, nor any association between hallucination frequency and context binding difficulties. The continuity model of hallucinations may overlook some important differences in hallucinatory experiences in the general population versus psychosis.
