A robotic procedure that creates sensorimotor conflicts and a feeling of another person's presence can induce auditory-verbal hallucination (AVH)-like sensations in healthy individuals. In two studies, participants showed increased false alarm rates on a voice detection task. Stronger sensorimotor conflicts led to more AVH-like sensations, supporting the self-monitoring deficit account. The otherness condition produced more false alarms when detecting other-voice stimuli than self-voice stimuli, consistent with the strong perceptual priors account. The findings integrate both theoretical models of AVH.
