“…Several reported that the recall of high susceptibles was less organized according to temporal cues than the recall of low susceptibles (Evans, 1980;Evans & Kihlstrom, 1973;Geiselman et al, 1983;Kihlstrom & Evans, 1979), two others failed to confirm this finding (Radtke & Spanos, 1981;St. Jean & Coe, 1981), and two recent studies found a significant relationship between temporal recall organization and hypnotic susceptibility but no significant differences between amnesics and non-amnesics on organization (Radtke, Spanos, Delia Malva, & Stam, 1986;Spanos, de Groh, & Bertrand, 1986). In sum, while a relationship between hypnotic susceptibility and temporal organization has sometimes been reported, this relationship has not always been associated specifically with hypnotic amnesia.…”

A series of three studies examined the effects of learning set, type of critical material, number of list presentations, and hypnotic susceptibility on the relationship between hypnotic amnesia and seriation.In Study 1 the critical stimuli were hypnotic test suggestions, and subjects were exposed to either an incidental or intentional learning set. Study 2 again manipulated learning set, but words served as the critical stimuli. Study 3 involved single versus multiple word list presentations prior to amnesia testing. No evidence for an amnesia-specific breakdown in seriation was obtained, and no consistent relationship between hypnotic susceptibility and changes in organization across recall trials emerged. Overall, the findings suggest that learning set, stimulus materials, and number of presentations cannot account for die discrepant findings obtained with the susceptibility scale and word list paradigms. The implications of these results for theories of hypnotic amnesia are discussed.

“…However, two other investigations largely failed to replicate the temporal effect and criticized the methodology by which the original findings were obtained (Radtke & Spanos, 1981;St. Jean & Coe, 1981; see also Radtke, Spanos, Della Malva, & Stam, 1986). In an experiment that addressed all of these criticisms, Kihlstrom and Wilson (1984) showed that temporal organization in a word list memorized by the method of serial learning is disrupted during posthypnotic amnesia, and that the extent of the disruption is highly correlated with the extent of partial amnesia.…”

Two experiments were performed to determine the fate of organization of recall during posthypnotic amnesia. In both studies, amnesia suggestions were administered to subjects of low, medium, and high hypnotic susceptibility who had learned a word list by the method of free recall while they were hypnotized. In Experiment 1, the words were unrelated to each other, and subjective o~aniTation was measured by raw and adjusted pair frequency (PF). In Experiment 2, the words were drawn from various taxonomic categories, and category clustering was measured by repetition ratio (RR), modified repetition ratio (MRR), and adjusted ratio of clustering (ARC). Compared to baseline levels, subjective organization and category clustering did not decrease reliably during the time the amnesia suggestion was in effect. Moreover, these aspects of strategic organization were not significantly correlated with the number of items recalled during amnesia. Both findings contrast with previous results concerning temporal organization of a word list memorized by the method of serial learning. The experiments suggest that the disruption of retrieval processes in posthypnotic amnesia may be limited to certain organizational schemes. In posthypnotic amnesia, hypnotized subjects fail to recall the events and experiences that occurred while they were hypnotized (Hilgard, 1965; Kihlstrom, 1985a, 1985b). The amnesia is a phenomenon of suggestion, a fact that differentiates it from the unsuggested state-dependent retrieval often produced by psychoactive drugs. Moreover, the amnesia can be reversed and memory restored following administration of a cue established at the time the original suggestion was given. During the time that the amnesia suggestion is in effect, the extent of recall deficit is correlated with individual differences in measured hypnotizability. Reversibility marks posthypnotic amnesia as a failure of memory retrieval. In attempting to understand this phenomenon, some investigators have used organization theory, an approach within cognitive psychology that focuses on the relations among items stored in memory (Bower, 1972; G. Mandler, 1979; J. Mandler, 1979; Tulving, 1962). Organization theory exists in various forms, but all agree that recall succeeds when the retrieval process follows the organization of the to-be-remembered material. From the point of view of organization theory, then, the retrieval disruption in posthypnotic amnesia may re
