Abstract
OBJECTIVES On the basis of the idea that thoughts held about pain may represent "self-suggestions" and evidence indicating that people with higher levels of trait hypnotizability are more responsive to suggestions, the current study evaluated hypothesized moderating effects of hypnotizability on the associations between pain-related thoughts and both pain intensity and pain interference. METHODS Eighty-five individuals with chronic pain were given measures of hypnotizability, pain intensity, pain interference, and pain-related thoughts (control beliefs, catastrophizing). RESULTS Analyses supported a moderating role of hypnotizability on the association between control beliefs and pain interference. Specifically, the negative association between pain control beliefs and pain interference were stronger among those with higher trait hypnotizability than between those with lower trait hypnotizability. DISCUSSION The study findings, if replicated in additional samples of individuals with chronic pain, have important clinical and theoretical implications. For example, if trait hypnotizability is found to predict an individual's response to a particular technique of cognitive therapy-such as focusing on and repeating pain control belief self-statements-measures of hypnotizability could be used to identify individuals who might be most responsive to this technique. The current findings indicate that research to further examine this possibility is warranted.

Abstract
Hypnotic, task-motivated and simulating subjects were administered a suggestion for a false memory (hearing noises) while “reliving” the events of an earlier night. Simulators reported the suggested noises more frequently than hypnotic subjects, and subjects in the three conditions failed to differ in endorsing the noises as real after termination of the “reliving” procedure. Subjects in the three conditions were also equally likely to reverse their pseudomemory reports following hidden observer instructions. These findings are consistent with the hypothesis that pseudomemory responding in this paradigm reflects reporting bias rather than memory distortion.

Abstract
False memory creation was examined in people who reported having recovered memories of traumatic events that are unlikely to have occurred: abduction by space aliens. A variant of the Deese/Roediger-McDermott paradigm (J. Deese. 1959; H. L. Roediger III & K. B. McDermott, 1995) was used to examine false recall and false recognition in 3 groups: people reporting recovered memories of alien abduction. people who believe they were abducted by aliens but have no memories, and people who deny having been abducted by aliens. Those reporting recovered and repressed memories of alien abduction were more prone than control participants to exhibit false recall and recognition. The groups did not differ in correct recall or recognition. Hypnotic suggestibility, depressive symptoms, and schizotypic features were significant predictors of false recall and false recognition.

Abstract
This experiment was designed to discern the proportion of false, inferential and verbatim memories that would be included in the reconstruction, one week later, of a 5 min narrative containing ambiguous but emotional content about a little boy. After 48 subjects were administered Spiegel's Hypnosis Induction Profile, they listened to the narrative, were exposed to one of four applications of transcerebral weak, complex magnetic fields for 30 min and then given either an accurate or inaccurate short summary of the story. One week later the group who received the erroneous summary reported more false memories about the original story than did the reference group; this treatment accommodated about 40% of the variance in numbers of false memories. Only an indicator of electrical lability within the temporal lobes (but not hypnotizability) was strongly associated with the numbers of inferential memories but not the numbers of false memories. The group that received transcerebral stimulation over the right hemisphere by a complex magnetic field and the erroneous summary reported three times the numbers of false memories compared to the other groups. Whereas verbatim memories showed a strong primacy effect inferential memories exhibited a strong recency effect (eta(2) =.66).

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.

Abstract
To define the relationship between aspects of memory concerning encoding and recall of short texts and hypnosis, standardized stories were narrated to 12 subjects, both during ordinary state of consciousness and after hypnotic induction by means of the Stanford Hypnotic Susceptibility Scale (Form C). The narrative material used as a stimulus was based on several stories taken from popular oral tradition, previously analyzed according to the classic criteria proposed by Rumelhart in 1975 and Mandler and Johnson in 1977. The subjects' memory performance during both experimental conditions was tape-recorded and compared with the analysis of the original stories (Terminal Nodes) as well as with the higher linguistic structures of the scheme (Basic Nodes), according to Rumelhart's typology. During hypnosis, the subjects recalled significantly fewer narrative elements at both levels of analysis (Terminal Nodes and Basic Nodes). We conclude that hypnosis does not enhance recent memory.

Abstract
We investigated if college students will create false childhood memories, the role of self-knowledge in memory creation, and if there are reliable individual differences related to memory creation. Based on information obtained from parents, we asked college students about several true childhood experiences. We also asked each student about one false event and presented the false event as if it was based on parent information. We asked the students to describe all events in two interviews separated by one day. When participants could not recall an event (whether true or false), we encouraged them to think about related self-knowledge and to try to imagine the event. In an unrelated experimental session, the students were administered four cognitive/personality scales: the Creative Imagination Scale (CIS), the Tellegen Absorption Scale (TAS), the Dissociative Experiences Scale (DES), and the Marlowe-Crowne Social Desirability Scale (SDS). We found that approximately 25% of the students created false childhood memories. Participants who made connections to related self-knowledge in the first interview were more likely to create false memories. We also found that the CIS and the DES were positively related to memory creation. Factors that decrease one's ability to engage in reality monitoring are related to the acceptance of false events and the creation of false memories.

Abstract
The effects of hypnosis, context reinstatement, and motivational instructions on accuracy of recall for factual information and facial recognition accuracy following a stressful event were assessed. None of the three techniques had a significant effect on factual memory or susceptibility to suggestion as assessed by true-false and multiple-choice tests. However, participants high in hypnotic susceptibility showed somewhat better memory on the true-false test, and hypnosis affected performance on the two photograph line-ups. In addition, hypnosis appeared to enhance facial recognition accuracy for participants who were low in anxiety, but not for those high in anxiety. Finally, there was evidence of a curvilinear relationship between self-reported anxiety at time of retrieval and facial recognition accuracy.

Abstract
This study investigated the relationship between resistance to misleading information and performance on the Harvard Group Scale of Hypnotic Susceptibility (HGSHS:A), and examined the impact of obtrusive observation on subjects' hypnotic responsivity, memory, and resistance to misleading information. Eighty-five college students were administered the HGSHS:A in its standard form. Three additional bogus items were added to the HGSHS:A response booklet asking subjects to report whether they responded to suggestions that were not actually offered during the procedures. The endorsement of these items was used as an index of resistance to misleading information (suggestibility) for events occurring during hypnosis. Participants were also given a series of misleading questions related to events that occurred prior to the induction. Results indicated that performance on the HGSHS:A was not related to resistance to misleading information for events occurring during hypnosis or for events that occurred prior to the induction. As predicted, resistance to misleading information was consistent for subjects across the waking and hypnotic contexts. Also as predicted, being observed during the hypnotic procedures was related to lower scoring on the HGSHS:A.

Abstract
A significant alteration in the hypnotizability of normal subjects after brief (15 min) exposures to weak (1 microT) pulsed magnetic fields over the temporal lobes was determined by the serial order of hemispheric stimulation. Only subjects who received the right hemispheric stimulation first displayed significantly elevated hypnosis induction profile scores (effect size equivalent to a correlation of 0.41). Implications for a technology that can: a) modify hypnotizability, b) encourage the consolidation of quasiexperiences that are reconstructed as autobiographical memory, and c) change the sense of self, are discussed.

Abstract
In this article we address a number of issues relevant to the practice of psychotherapy and hypnotherapy: How reliable is memory? How are therapists' and clients' beliefs and expectancies related to pseudomemory formation? Are certain clients particularly vulnerable to pseudomemory creation? Does hypnosis pose special hazards for pseudomemory reports? What are the variables or factors that mediate hypnotic pseudomemories? In addition to reviewing the literature on these topics, we intend to sensitize the clinician to the potential pitfalls of critical reliance on the patient's memories, as well as uncritically accepted clinical beliefs and practices.

Abstract
The mental health field is deeply divided in its views regarding the possibility of creating false memories of sexual abuse through suggestive procedures. Psychotherapists in clinical practice were surveyed regarding their views on memory and hypnosis in order to assess how their perspectives might influence their clinical methods. Survey data regarding hypnosis and suggestibility indicate that while psychotherapists largely view hypnosis favorably, they often do so on the basis of misinformation. A significant number of psychotherapists erroneously believe, for example, that memories obtained through hypnosis are more likely to be accurate than those simply recalled, and that hypnosis can be used to recover accurate memories even from as far back as birth. Such misinformed views can lead to misapplications of hypnosis when attempting to actively recover memories of presumably repressed episodes of abuse, possibly resulting in the recovery of suggested rather than actual memories.

Abstract
20 normal young women listened to an ambiguous story concerning a young boy who experienced fear, odd smells, and a smothering sensation during the night and skin lesions the next morning. After the Hypnotic Induction Profile (HIP) had been established, they were asked to estimate either the percentage prevalence of childhood sexual abuse or alien abduction in the general population. There were moderate (0.50) positive correlations between the subjects' estimates of prevalence and the amount of amnesia ("lost time") and indices of right-hemispheric anomalies (history of sensed presence and left-ear suppressions during a dichotic-listening task). Relevance of observations to formation of the False Memory Syndrome and to the development of nonpsychotic delusions is discussed.

Abstract
Two sessions were conducted in which independent groups of 86 high- and 85 low-susceptible subjects, responding individually under waking or hypnotic instruction, answered high- and low-cued leading questions about a video event that depicted shooting at an airport. The two sessions were separated by 1 week, and the same questions were asked in both sessions. It was predicted that highly susceptible subjects responding under hypnotic instruction would show the most evidence of accepting false information via strongly cued leading questions. Results showed general effects for leading questions and level of susceptibility but no firm support for the involvement of hypnosis. Data are discussed in terms of both the linguistic and social factors that appear to have operated on subjects in the study, results overall highlight the strong influence of level of susceptibility on subjects' acceptance of false information.

Abstract
Hypnotizable (N = 9) and simulating subjects (N = 8) were age regressed to the previous week's hypnosis session and received a suggestion to hear a phone ring during the earlier session (no phone actually rang). Pseudomemory rates in response to open-ended questions were low in this study (0% hypnotizable and simulating subjects) and in previous research (Lynn, Weekes, & Milano, 1989; 12.5% hypnotizable; 10% simulating subjects) in which the phone-ring suggestion was not embedded in the context of age regression. In response to a forced-choice question, 22.22% of the hypnotizable and 25% of the simulating subjects indicated that the suggested phone ring was an actual event, a pseudomemory rate somewhat higher than our previous study in which none of the subjects reported pseudomemories in response to a forced-choice question. When the occurrence of the target stimulus of a pseudomemory suggestion is publicly verifiable, the pseudomemory rate is low.

Abstract
Six adults, who had recently experienced sudden recall of preschool memories of sex abuse or alien abduction/visitation, were given complete neuropsychological assessments. All experiences "emerged" when hypnosis was utilized within a context of sex abuse or New Age religion and were followed by reduction in anxiety. As a group, these subjects displayed significant (T greater than 70) elevations of childhood imaginings, complex partial epileptic-like signs, and suggestibility. Neuropsychological data indicated right frontotemporal anomalies and reduced access to the right parietal lobe. MMPI profiles were normal. The results support the hypothesis that enhanced imagery due to temporal lobe lability within specific contexts can facilitate the creation of memories; they are strengthened further if there is also reduction in anxiety.
