Sensory suppression occurs when hearing one’s self-generated voice, as opposed to passively listening to one’s own voice. Quality changes in sensory feedback to the self-generated voice can increase attentional control. These changes affect the self-other voice distinction and might lead to hearing voices in the absence of an external source (ie, auditory verbal hallucinations). However, it is unclear how changes in sensory feedback processing and attention allocation interact and how this interaction might relate to hallucination proneness (HP).

Participants varying in HP self-generated (via a button-press) and passively listened to their voice that varied in emotional quality and certainty of recognition—100% neutral, 60%–40% neutral-angry, 50%–50% neutral-angry, 40%–60% neutral-angry, 100% angry, during electroencephalography (EEG …
