Hypnosis and Trance States

by Joe Griffin and Ivan Tyrrell

Published 19 November 2003
A fully-referenced explanation of hypnosis from an evolutionary perspective. It offers scientists, researchers, psychologists, psychotherapists, hypnotherapists and the interested lay public an explanatory "organizing idea" in order to widen and deepen their understanding of the subject. It resolves the controversy over whether hypnosis is an altered state of consciousness or not.
