Hypnosis, memory, and frontal executive functioning.

Abstract

According to the dissociated-control hypothesis forwarded by Woody and Bowers (1994), the effects of hypnosis are consistent with attenuated frontal lobe functioning. The present study was designed to compare the performance of participants with high and low hypnotic ability on a variety of memory tasks thought to be sensitive to frontal lobe functioning, as well as some control memory tasks not considered to be sensitive to such functioning. Results generally indicated that participants with high hypnotic ability have more difficulty with tasks sensitive to frontal lobe functioning, including free recall, proactive interference, and source amnesia tasks, both within and outside of the context of hypnosis. These differences, which were not found for nonfrontal tasks, are generally supportive of the dissociated control theory of hypnotic responding.
