Eliciting autobiographical pseudomemories: the relevance of hypnosis, hypnotizability, and attributions

Abstract

The authors investigated the roles of hypnosis, hypnotizability, and attributions in autobiographical pseudomemories. Experiment 1 administered a suggestion for recall of their second birthday to hypnotized high and low hypnotizable participants and nonhypnotized, high hypnotizable participants; Experiment 2 administered a similar suggestion to real and simulating participants. Recall was tested during hypnosis, after hypnosis, and after a challenge procedure. In Experiment 1, more highs than lows reported a memory during hypnosis; however, following the challenge, half the walking highs but none of the hypnosis highs retracted their memory. Notably, highs attributed their memories to reconstructions based on other birthdays. In Experiment 2, whereas an equal number of reals and simulators reported a memory of their second birthday during hypnosis and then retracted following the challenge, they made different attributions about their memories. These findings highlight the value of a closer investigation of attributional processes that reconcile believed-in autobiographical memories with conflicting evidence.
