Auditory hallucinations (also known as Paracusia), particularly of one or more talking voices, are particularly associated with psychotic disorders such as schizophrenia, and hold special significance in diagnosing these conditions, although many people not suffering from diagnosable mental illness may sometimes hear voices as well. The Hearing Voices Movement is a support and advocacy group for people who hallucinate voices, but do not otherwise show signs of mental illness or impairment. Other types of auditory hallucinations include musical hallucinations, where people will hear music playing in their mind, usually songs they are familiar with. This can be caused by: lesions on the brain stem (often resulting from strokes); also, tumors, encephalitis, or abscesses. Other reasons include hearing loss and epileptic activity. Recent reports have also mentioned that it is also possible to get musical hallucinations from listening to music for long periods of time.
Epidemiology of hearing voices
For example, Bentall and Slade (1985) found that as many as 15.4% of a population of 150 male students were prepared to endorse the statement ‘In the past I have had the experience of hearing a person’s voice and then found that no one was there’. They add: ‘[…]no less that 17.5% of the [subjects] were prepared to score the item “I often hear a voice speaking my thoughts aloud” as “Certainly Applies”. This latter item is usually regarded as a first-rank symptom of schizophrenia[…]’
Green and McCreery (1975) found that 14% of their 1800 self-selected subjects reported a purely auditory hallucination, and of these nearly half involved the hearing of articulate or inarticulate human speech sounds. An example of the former would be the case of an engineer facing a difficult professional decision, who, while sitting in a cinema, heard a voice saying, ‘loudly and distinctly’: ‘You can’t do it you know’. He adds: ‘It was so clear and resonant that I turned and looked at my companion who was gazing placidly at the screen[…] I was amazed and somewhat relieved when it became apparent that I was the only person who had heard anything.’
This case would be an example of what Posey and Losch (1983) call ‘hearing a comforting or advising voice that is not perceived as being one’s own thoughts’. They estimated that approximately 10% of their population of 375 American college students had had this type of experience.
