Abstract

The subjective experience conferred by auditory perception has rarely been addressed outside of the studies of auditory hallucinations.

The aim of this study is to describe the phenomenology of auditory experiences in individuals who endorse magical beliefs, but do not report hallucinations.

We examined the relationship between subjective auditory sensitivity and a ‘psychotic-like’ thinking style. Hyperacusis questionnaire scores were compared between 25 high scoring participants on Chapman's magical ideation (MI) scale, 25 high scoring participants on Chapman's physical anhedonia scale and 25 control participants, pre-selected from a large student pool (n = 1289).

The participants who obtained high scores on the MI scale rated their auditory sensitivity higher than the two other groups.

Our results indicate that, in healthy subjects, subjective auditory sensitivity is associated with MI without the mediation by anxiety commonly observed in pathological cases.

We propose that hyperacusis associated to high scores of MI may be a predispositional factor to deviant auditory experiences.

The relative uncoupling of perception from auditory sensory input may result in a central hypersensitivity, which could play a role in triggering off the experience of auditory hallucinations.
