The only really contentious point in this description of conscious processes is the claim that
executive processes initiate action. Drawing on research carried out by Benjamin Libet
during 1985, the year that Hilgard revised Divided Consciousness,
Robert Ornstein argues
that even when action appears to be initiated by conscious processes it is unconscious ones
that are often the real driving force. Libet’s work was concerned with what he called
‘readiness potential’ brainwaves. These occur only before movements we experience as
being consciously willed whether they be calculated or spontaneous. They begin around a
second before we become conscious of making a decision to act.
It seems then, that even
many of the activities which seem to be initiated by our conscious selves would appear to be
generated unconsciously – albeit in response to a consciously thought out plan.18
When the conscious mind is displaced or dissociated unconscious processes are given a free
rein as it were, guided only by the directions of the hypnotist, the social context or some
goal determined prior to or during the induction procedure. Trance experience is thus
significantly different from ordinary experience. Gilligan enumerates and describes its
principal features. These include attentional absorption, involuntariness, immersion in
experiential and symbolic rather than conceptual processing,
enhanced suggestibility,
perceptual flexibility, trance logic
and a tendency to be amnesic for trance experiences on
return to ordinary consciousness
