Body Map of a Psychotic Hallucination

Leicester psychologists have, for the first time, created body-maps of the sensations which arise during hallucinations in people experiencing psychosis. Although there was great variation in the localisation of feelings across participants, for each individual feelings were recurrently concentrated in particular body areas. Areas of concentration often held repeated sources of feelings like pain, heat, or tension. Psychosis is a term which describes experiences where an individual may have difficulties in determining what is real and what is not real. Research indicates psychosis is associated with experiencing trauma, adverse life events, and stress. People may be given a diagnosis such as schizophrenia. Experiences of perceiving or believing things which those around us do not can also occur in physical health conditions such as brain tumours or acute infections.

Psychosis can have serious adverse outcomes on individuals including distress, lack of sleep, social withdrawal, lack of motivation, difficulties in carrying out daily activities, experiences of discrimination and lost opportunities. Participants were asked by the research team to prospectively document the feeling and senses of hallucinations for one week prior to an interview. Novel visual diary methods involving drawing, writing and body-mapping generated 42 MUSE maps, which set out the specific areas across the body and beyond where participants experienced sensations during hallucinations. The study found that hallucinations were characterised by numerous feelings arising at once, often including multisensory, emotional, and embodied features. Researchers suggest further uptake of visual, ecological and prospective methods may enhance understandings of lived experiences of hallucinations.
