A seminal work on the unconscious and its mechanisms. Examines the interaction between voluntary (conscious) and involuntary (unconscious) human control mechanisms in terms of dissociation of divided consciousness. Delineates a neodissociation interpretation that recognizes historical roots without requiring commitment. Presents a wide range of data on possession states, fugues, multiple personalities, amnesia, dreams, hallucinations, automatic writing, and aggressions.

The well-known behaviorist revolt against consciousness is largely in the past, although that does not mean that the new interest in consciousness is without many unsolved problems. Cognitive psychology, as an alternative, is not necessarily a consciousness psychology, and humanistic psychology, friendly to consciousness, has difficulty in maintaining scientific status. One approach to consciousness is by way of dissociation, the phenomena of which can be found in everyday experience but can be studied in more detail through hypnosis. One aspect of (...) hypnosis research has led to the concept of a “hidden observer,” a metaphor used to indicate that some information is processed and has consequences without being in the focus of consciousness at the time, but is recoverable through hypnosis. The evidence comes mostly from subjects highly responsive to hypnosis, so that generalizations must be used with caution. The divisions of consciousness lead to consideration of its executive and monitoring functions-normal functions, but subject to some alterations through hypnosis. (shrink)
