Is the hypnotized subject lying?

Do the verbal reports of deeply hypnotized Ss truthfully reflect their subjective experiences of hypnotic suggestions? Experiment 1 established that the electrodermal skin conductance response (SCR) provides an effective method for detecting deception in the laboratory equally well in hypnotized and nonhypnotized Ss. In Experiment 2, deeply hypnotized and simulating Ss were administered a number of hypnotic suggestions in a typical hypnotic session, without mention of deception, and were questioned about their experiences while SCR measures were recorded concurrently. Results indicate that 89% of the hypnotized Ss' reports met the criterion for truthfulness, whereas only 35% of the simulators' reports met this criterion. Implications for the theory of hypnosis are discussed.
