Variables affecting subjective organization during posthypnotic amnesia

Abstract

Subjects learned a list of unrelated words to a criterion of either two successive correct trials (standard criterion), or two successive correct trials plus five additional recall trials (extra criterion). The extra recall trials significantly increased the subjective organization of recall. In the extra criterion group, a posthypnotic amnesia suggestion and a nonhypnotic distraction task produced equivalent decrements both in the amount recalled and in the subjective organization of recall. In the standard criterion group, suggestion and distraction reduced the amount recalled, but not the subjective organization of recall. The implications of these findings for understanding the contradictory results of earlier studies of recall organization during amnesia are discussed. Implications for theories of hypnotic amnesia are also discussed.
