N2 - Hallucination is defined in the diagnostic systems as an experience resembling true perception without causal stimulus. In this second report from an in-depth phenomenological study of schizophrenia patients experiencing auditory verbal hallucinations (AVHs), we focused on the phenomenological qualities of AVHs. We found that a substantial proportion of patients could not clearly distinguish between thinking and hallucinating. The emotional tone of the voices increased in negativity. AVHs became more complex. Spatial localization was ambiguous and only 10% experienced only external hallucinations. There was an overlap with passivity phenomena in one third of the cases. The patients occasionally acted upon the content of AVHs. In the discussion section, we criticize the perceptual model of AVHs. We conclude that the definition of AVH in schizophrenia is misleading and exerts negative consequences on the clinical work and empirical research.
