Comparative Study
Perception, mental imagery and reality discrimination in hallucinating and non-hallucinating schizophrenic patients.
In this study the hypothesis was tested that hallucinations result from confusing external and internal stimulus sources, i.e., perception and imagery, respectively. ⋯ Hallucinations may result from increased vividness of mental imagery, and their severity increases with larger impairments in reality discrimination. It is recommended that research into, and cognitive behavioural therapy for, hallucinations should also focus on their sensory qualities.
