The question of hypnotic subjects complying with instructions, perhaps even purposely deceiving the hypnotist or deceiving themselves, has arisen from the state-nonstate (skeptical-credulous) theoretical controversy. However, experimental testing of competing hypotheses has been difficult. The current report offers methodological procedures that may prove useful. Subjects who were given posthypnotic amnesia instructions were tested on free recall and implicit recall of a 20-word list. To detect the possibility of deception, videotapes of real subjects and simulating subjects during and after posthypnotic amnesia were rated for nonverbal signs of deception, signs taken from the works of Ekman, Ekman and Friesen, and Zuckerman et al. Preliminary results were gathered on a small pilot sample, and recommendations for procedural improvements are proposed.
