Auditory verbal hallucinations: The ins and outs of subtypes.

Background: Voice-hearing in psychosis is a heterogeneous and often distressing experience. Phenomenological studies have proposed the existence of several subtypes of auditory verbal hallucinations (AVHs) that may guide intervention, such as inner-speech based voices (ISVs), hypervigilance voices (HVs) and memory-based voices, but empirical data is scarce. We developed a detailed coding scheme with the aim of examining whether distinct subtypes of AVHs could be reliably identified and characterised in an early psychosis sample.

What can neurodiversity tell us about inner speech, and vice versa? A theoretical perspective.

Inner speech refers to the experience of talking to oneself in one's head. While notoriously challenging to investigate, it has also been central to a range of questions concerning mind, brain, and behaviour. Posited as a key component in executive function and self-regulation, inner speech has been claimed to be crucial in higher cognitive operations, self-knowledge and self-awareness.

Intentional inhibition but not source memory is related to hallucination-proneness and intrusive thoughts in a university sample.

Proneness to unusual perceptual states - such as auditory or visual hallucinations - has been proposed to exist on a continuum in the general population, but whether there is a cognitive basis for such a continuum remains unclear. Intentional cognitive inhibition (the ability to wilfully control thoughts and memories) is one mechanism that has been linked to auditory hallucination susceptibility, but most evidence to date has been drawn from clinical samples only. Moreover, such a link has yet to be demonstrated over and above relations to other cognitive skills (source monitoring) and cognitive states (intrusive thoughts) that often correlate with both inhibition and hallucinations.

The varieties of inner speech questionnaire - Revised (VISQ-R): Replicating and refining links between inner speech and psychopathology.

Inner speech is a common experience for many but hard to measure empirically. The Varieties of Inner Speech Questionnaire (VISQ) has been used to link everyday phenomenology of inner speech - such as inner dialogue - to various psychopathological traits. However, positive and supportive aspects of inner speech have not always been captured.

Uncharted features and dynamics of reading: Voices, characters, and crossing of experiences.

Readers often describe vivid experiences of voices and characters in a manner that has been likened to hallucination. Little is known, however, of how common such experiences are, nor the individual differences they may reflect. Here we present the results of a 2014 survey conducted in collaboration with a national UK newspaper and an international book festival.

Hearing voices in the resting brain: A review of intrinsic functional connectivity research on auditory verbal hallucinations.

Resting state networks (RSNs) are thought to reflect the intrinsic functional connectivity of brain regions. Alterations to RSNs have been proposed to underpin various kinds of psychopathology, including the occurrence of auditory verbal hallucinations (AVH). This review outlines the main hypotheses linking AVH and the resting state, and assesses the evidence for alterations to intrinsic connectivity provided by studies of resting fMRI in AVH.

Shot through with voices: dissociation mediates the relationship between varieties of inner speech and auditory hallucination proneness.

Inner speech is a commonly experienced but poorly understood phenomenon. The Varieties of Inner Speech Questionnaire (VISQ; McCarthy-Jones & Fernyhough, 2011) assesses four characteristics of inner speech: dialogicality, evaluative/motivational content, condensation, and the presence of other people. Prior findings have linked anxiety and proneness to auditory hallucinations (AH) to these types of inner speech.
