ABSTRACT

Hallucinations are a hallmark symptom of schizophrenia. Although they can occur in the auditory, visual, olfactory, gustatory and somatosensory modalities, approximately 70% of individuals diagnosed with schizophrenia report hallucinations in the auditory modality (Andreasen and Flaum 1991). Auditory hallucinations can occur in the context of a wide range of psychiatric disorders, but their prevalence is highest in patients with schizophrenia (American Psychiatric Association 2000). The present chapter focuses on auditory hallucinations in schizophrenia. Research findings on hallucinatory experiences in other disorders and in healthy individuals have been recently synthesized elsewhere and will not be covered here (Jardri et al. 2013; Blom and Sommer 2012).
