Hypnotic subjects were administered a suggestion to forget a previously overlearned word list. Before cancellation of the suggestion they were challenged twice to try and recall the words. Subjects in one group received a second challenge immediately after response to the first. Those in the second group were given a 15-min. delay before their second challenge. Subjects in both groups showed less amnesia after the second challenge than after the first, but the length of delay between challenges had no effect on amnesia scores. These findings are inconsistent with the hypothesis that hypnotic amnesia involves an involuntary blockage of memory that decays spontaneously with time.
