Title: “Auditory Verbal Hallucinations and the Anticipatory Nature of Experience”
Abstract: My aim is to formulate an account of auditory-verbal hallucinations (AVHs) occurring in the context of schizophrenia, which is both informed by empirical findings and does justice to the subjective experience of voice-hearing. I argue that AVHs cannot be fully understood in isolation from their broader experiential context. They are symptomatic of global experiential changes, and any complete account of them needs to understand these changes. I start by attempting to formulate a clearer statement of what is involved, phenomenologically speaking, by looking closely at first-person patient reports. I then explain these phenomenological changes in terms of recent work on “hierarchical predictive processing” (HPP) (see Clark 2013, for a review). I present data suggesting that schizophrenia involves predictive processing going wrong. I then show how this predictive processing view supports a recent distinction between “inner speech hallucinations”, which occur in quiet contexts where attention is inwardly directed, and “hypervigilance hallucinations”, which occur in loud contexts where attention is outwardly directed (Dogdson and Gordon 2009).
