Immediate and persisting effects of misleading questions and hypnosis on memory reports were assessed. After listening to a story, 52 highly suggestible students and 59 low and medium suggestible students were asked misleading or neutral questions in or out of hypnosis. All participants were then asked neutral questions without hypnosis. Both hypnosis and misleading questions significantly increased memory errors, and misleading questions produced significantly more errors than did hypnosis. The 2 effects were additive, so that misleading questions in hypnosis produced the greatest number of errors. There were no significant interactions with level of hypnotic suggestibility. Implications of these findings for the per se exclusion of posthypnotic testimony are discussed.

Study in Nature Neuroscience uncovers possible basis of short-term memory

CLEVELAND - Ben W. Strowbridge, PhD, associate professor of neuroscience and physiology/biophysics, and Phillip Larimer, PhD, a MD/PhD student in the neurosciences graduate program at Case Western Reserve University School of Medicine, are the first to create stimulus-specific sustained activity patterns in brain circuits maintained in vitro.

Their study, entitled, "Representing information in cell assemblies: Persistent activity mediated by semilunar granule cells" will be published in the February 2010 issue of Nature Neuroscience and is currently available online.

Neuroscientists often classify human memory into three types: declarative memory, such as storing facts or remembering specific events; procedural memory, such as learning how to play the piano or shoot basketballs; and working memory, a type of short-term storage like remembering a phone number. With this particular study, Strowbridge and Larimer, were interested in identifying the specific circuits that could be responsible for working memory.

The remember-know paradigm is one of the most widely used procedures to examine the subjective experience associated with memory retrieval. We examined how the terminology and instructions used to describe the experiences of remembering and knowing affected remember-know judgments. In Experiment 1 we found that using neutral terms, i.e., Type A memory and Type B memory, to describe the experiences of remembering and knowing reduced remember false alarms for younger and older adults as compared to using the terms Remember and Know, thereby increasing overall memory accuracy in the neutral terminology condition. In Experiment 2 we found that using what we call source-specific remember-know instructions, which were intended to constrain remember judgments to recollective experiences arising only from the study context, reduced remember hits and false alarms, and increased know hits and false alarms. Based on these data and other considerations, we conclude that researchers should use neutral terminology and source-specific instructions to collect the most accurate reports of the experiences of remembering and knowing arising from the study context.

Full Title: Are subjective memory problems related to suggestibility, compliance, false memories, and objective memory performance?

The relationship between subjective memory beliefs and suggestibility, compliance, false memories, and objective memory performance was studied in a community sample of young and middle-aged people (N = 142). We hypothesized that people with subjective memory problems would exhibit higher suggestibility and compliance levels and would be more susceptible to false recollections than those who are optimistic about their memory. In addition, we expected a discrepancy between subjective memory judgments and objective memory performance. We found that subjective memory judgments correlated significantly with compliance, with more negative memory judgments accompanying higher levels of compliance. Contrary to our expectation, subjective memory problems did not correlate with suggestibility or false recollections. Furthermore, participants were accurate in estimating their objective memory performance.

To explore the nature of past-life memories in hypnosis, 64 normal male adults aged 21 to 23 were selected using the Korean version of the Harvard Group Scale of Hypnotic Susceptibility (HGSHS:K) and a simple belief in past-life scale. They all received hypnotic past-life regression 3 times. The influence of HGSHS:K scores on the production rate of past-life memories was statistically significant; however, the influence of belief was not. The percentage of subjects who responded to hypnotic past-life regression increased with hypnotizability. Content analysis showed that cultural background and religious concepts influenced past-life memory production. Animals as past-life identities, for example, were reported whereas all past-life identities were human in a Canadian study.

People falsely endorse semantic associates and morpheme rearrangements of studied words at high rates in recognition testing. The coexistence of these results is paradoxical: Models of reading that presume automatic extraction of meaning cannot account for elevated false memory for foils that are related to studied stimuli only by their visual form; models without such a process cannot account for false memory for semantic foils. Here we show how sentence and list study contexts encourage different encoding modes and consequently lead to different patterns of memory errors. Participants studied compound words, such as tailspin and floodgate, as single words or embedded in sentences. We show that sentence contexts led subjects to be better able to discriminate conjunction lures (e.g., tailgate) from old words than did list contexts. Conversely, list contexts led to superior discrimination of semantic lures (e.g., nosedive) from old words than did sentence contexts.

Children in two age groups (7 vs. 12 yrs, N= 174) individually interacted with a stranger and were later interviewed about this event. Right before the interview, each child encountered the stranger once again and he engaged in a conversation where he either suggested that a (central or peripheral) detail originally present in the event had actually not been there or that an originally non-present (central or peripheral) detail had in fact been there. It was hypothesized that the two types of misinformation would result in omission and commission errors respectively. The results showed that the social influence resulted in an asymmetric effect (i.e., more commission than omission errors). Importantly, we also found that the children made more errors with respect to the peripheral detail (a suitcase), compared to the central detail (a passenger). Younger children did not make more errors (neither omission nor commission errors) than older children.

We explored whether event recency and valence affect people's susceptibility to imagination inflation. Using a three-stage procedure, subjects imagined positive and negative events happening in their distant or recent past. First, subjects rated how confident they were that they had experienced particular positive and negative events in childhood or adulthood using a Life Events Inventory (LEI). Two weeks later, they imagined two positive and two negative events from the LEI. Finally, they rated their confidence on the LEI a second time. For positive events, subjects showed more imagination inflation for adulthood than childhood events. For negative events, they showed no difference in imagination inflation for adulthood and childhood events. We discuss factors that may influence source confusions for memories of the past and highlight directions for future research.

This experiment aimed to create a laboratory analogue of déjà vu. During hypnosis, 1 group of high hypnotizables completed a puzzle game and then received a posthypnotic amnesia suggestion to forget the game (PHA condition). Another group of highs were not given the game but received a posthypnotic familiarity suggestion that it would feel familiar (PHF condition). After hypnosis, all participants were given the game and described their reactions to it. Whereas 83% of participants in both conditions passed their respective suggestions, more in the PHF condition felt a sense of déjà vu. An EAT inquiry revealed that they experienced sensory fascination and confusion about the source of familiarity, akin to everyday déjà vu. These findings highlight the value of using hypnosis as a laboratory analogue of déjà vu and provide a framework for investigating clinical manifestations of this phenomenon.

The authors examined the relation between children's narrative ability, which has been identified as an important contributor to memory development, and suggestibility. Across 2 studies, a total of 112 preschool-aged children witnessed a staged event and were subsequently questioned suggestively. Results from Study 1 indicated that children's ability to provide a high-quality narrative of the event was related to resistance to suggestive questions, and narrative ability appeared to supersede age as a predictor of such resistance. In Study 2, children's general language and narrative abilities were measured in addition to their ability to produce a high-quality narrative about the target event. These results replicated Study 1's findings that children's ability to produce a high-quality narrative of a previously experienced event predicted resistance to suggestion. However, the quality of children's autobiographical memory narratives predicted shifting from denial to assent. Findings are considered in light of narrative's role in memory development and underlying mechanisms that may explain children's suggestibility.

Occasionally I'll encounter 40-ish or older male patients who are encountering learning, memory, and motivation problems. During their intake and subsequent discussions I often detect similar patterns. They are individuals who are successful in their professional lives. Yet, they tend to be over controlling workaholics who equate effort with results. I've even heard more than one of them using the phrase "no pain, no gain." Indeed, too often they equate personal sacrifice with results. This leads to an unbalanced life which will eventually affect their effectiveness. In short, trying too hard will lead to ineffectiveness, a loss of control of their temper, and health problems. To merely treat the presenting memory and motivation problem blindly with hypnosis or allopathic remedies would be unfruitful and potentially harmfully.

Research on memory conformity shows that collaborative remembering--typically in the form of discussion--can influence people's memories. One question that remains is whether it matters with whom we discuss our memories. To address this question we compared people's memories for an event after they discussed that event with either their romantic partner or a stranger. Pairs of subjects watched slightly different versions of a movie, and then discussed some details from the movie, but not others. Subjects were better at remembering non-discussed details than discussed details: when remembering discussed details they incorrectly reported information from their partner's version instead of their own. In addition, subjects who discussed the event with their romantic partner (rather than with a stranger) were even more likely to report false memories. We discuss our findings in relation to other research on memory conformity, social influences on false memories, and memory systems within romantic relationships.

Three experiments explored a jumbled word effect in false recognition. Lists of theme-related items were presented in word or nonword form. Results indicated that critical lures semantically related to studied items were falsely recognised regardless of whether they were presented as words or nonwords. High false recognition rates to either SLEEP or SELEP following study of an appropriate theme list of items in nonword form should only occur if nonwords are recoded at study. With study conditions conducive to recoding, jumbled words induced false recognitions based on semantic associations among their respective base words. Disrupting a recoding process by creating "difficult" letter rearrangements for jumbled words (Experiment 2) appeared to eliminate the false recognition effect. In Experiment 3, presentation durations ranged from 110 ms to 880 ms. Although there was little evidence of a semantic false recognition effect at the fastest presentation rate, the brief durations appeared to be effective in eliminating the effect when items were studied in nonword form. These results appear to be consistent with an encoding activation/retrieval monitoring model.

We investigated the influence of preparation provided by parents on preschoolers' recall. One day before children participated in a staged novel event, parents discussed the event with their child either with (verbal+photos) or without (verbal) photographs. Parents and children in a control condition read an unrelated story. Then 8-10 days later the children were interviewed about the event. Children in the verbal+photos condition recalled significantly more than those in the control condition. Parental preparation style (e.g., evaluations, hypothetical language) was associated with the child's contributions to the preparatory discussion, but no aspect of parent or child style or content was associated with children's verbal recall. Similarly, there were no significant associations between children's performance on a task of episodic future thinking, and their preparatory discussion or recall, although episodic future thinking was strongly associated with language ability. The potential underlying mechanisms and theoretical implications are discussed.

Many people believe that emotional memories (including those that arise in therapy) are particularly likely to represent true events because of their emotional content. But is emotional content a reliable indicator of memory accuracy? The current research assessed the emotional content of participants' pre-existing (true) and manipulated (false) memories for childhood events. False memories for one of three emotional childhood events were planted using a suggestive manipulation and then compared, along several subjective dimensions, with other participants' true memories. On most emotional dimensions (e.g., how emotional was this event for you?), true and false memories were indistinguishable. On a few measures (e.g., intensity of feelings at the time of the event), true memories were more emotional than false memories in the aggregate, yet true and false memories were equally likely to be rated as uniformly emotional. These results suggest that even substantial emotional content may not reliably indicate memory accuracy.

Information about stressful life experiences obtained from patients during diagnostic interviews is an important foundation for clinical decision making. In this study self-reports from 115 committed psychiatric patients of experiences of mechanical restraint were compared with medical records. The sensitivity of patient self-reports was 73% (11/15) and the specificity was 92% (92/100). No clear relationship between psychiatric symptoms and reliability of self-reports was identified. The results highlight the subjective qualities of narratives about past experiences.

Despite a large body of false memory research, little has addressed the potential influence of an event's emotional content on susceptibility to false recollections. The Paradoxical Negative Emotion (PNE) hypothesis predicts that negative emotion generally facilitates memory but also heightens susceptibility to false memories. Participants were asked whether they could recall 20 "widely publicised" public events (half fictitious) ranging in emotional valence, with or without visual cues. Participants recalled a greater number of true negative events (M=3.31/5) than true positive (M=2.61/5) events. Nearly everyone (95%) came to recall at least one false event (M=2.15 false events recalled). Further, more than twice as many participants recalled any false negative (90%) compared to false positive (41.7%) events. Negative events, in general, were associated with more detailed memories and false negative event memories were more detailed than false positive event memories. Higher dissociation scores were associated with false recollections of negative events, specifically.

Prior research on false memories has shown that suggestibility is often reduced when the presentation rate is slowed enough to allow monitoring. We examined whether slowing presentation speed would reduce factual errors learned from fictional stories. Would subjects use the extra time to detect the errors in the stories, reducing reproduction of these errors on a later test? Surprisingly, slowing presentation speed increased the production of story errors on a later general knowledge test. Instructing the reader to mark whether each sentence contained an error, however, did decrease suggestibility. Readers appear to passively accept information presented in stories and need a constant reminder to monitor for errors. These results highlight differences between typical episodic false memories and illusions of knowledge (such as learning from fiction). Manipulations that reduce suggestibility for episodic false memories do not always reduce suggestibility for illusions of knowledge.

Do false beliefs last? To explore this question, this study planted false beliefs or memories of a childhood experience with asparagus. We found that these false beliefs had consequences for subjects, when assessed directly after the suggestive manipulation. Moreover, subjects were brought back two weeks later to see if their false beliefs persisted. After two weeks, subjects' confidence in their new memories, and the consequences of those memories were diminished, but not extinguished. These false beliefs were found to be somewhat weaker than other subjects' true beliefs for the same events. Another novel finding was that the manipulation was sufficiently powerful to affect actual food choices.

The influence, if any, of emotional arousal on memory is a controversial topic in the literature. Much of the research on memory for emotionally arousing events has focused on a few specific issues (e.g., differences in types of details recalled in emotionally arousing and neutral events; increasing ecological validity). Although gaining more recent attention, a neglected area in the literature has been memory for instances of repeated, emotionally arousing events. This issue has important implications for understanding children's ability to recall events in a forensic setting. We review existing findings on memory for emotionally arousing events in general and particularly in children, children's memory for events that occur repeatedly, and then discuss the scarce research on repeated emotionally arousing events and the need for further research in this area. We conclude that although it is clear that children are capable of accurately reporting arousing and repeated experiences, it is also apparent that circumstances both within and outside the control of investigative interviewers influence this ability.

OBJECTIVE: Two studies examined the effects of the oath or reassurance ("truth induction") on 5- to 7-year-old maltreated children's true and false reports of a minor transgression. METHODS: In both studies an interviewer elicited a promise to tell the truth, reassured children that they would not get in trouble for disclosing the transgression, or gave no instructions before questioning the child. In Study 1, children were encouraged to play with an attractive toy by a confederate, who then informed them that they might get in trouble for playing. In Study 2, a confederate engaged children in play, but did not play with the attractive toy. RESULTS: In Study 1, the oath and reassurance increased disclosure among children who would qualify as competent to take the oath. In Study 2 neither the oath nor reassurance increased false reports among children who would qualify as competent, whether yes/no questions or tag questions were asked. Among non-competent children, reassurance (but not the oath) increased false reports. Children were more likely to accuse the confederate of the transgression than to implicate themselves. CONCLUSIONS: The results suggest that a promise to tell the truth may increase true disclosures without increasing false allegations. Reassurance that specifically mentions the target activity also increases true disclosures, but may increase acquiescence among some children. PRACTICE IMPLICATIONS: A child-friendly version of the oath may be a useful addition to child interviews.

The memory (and hypnosis) lab at the University of New South Wales investigates a broad range of memory topics. We try to find innovative methods from cognitive and clinical psychology to address theoretical and empirical questions about memory. We aso use hypnosis as one major methodological tool in our investigations of memory (as well as other cognitive processes). In this paper, we review the projects currently underway in our memory (and hypnosis) lab.

We explore a new distinction between the future, prospective memory system being investigated in current neuroscience and the past, retrospective memory system, which was the original theoretical foundation of therapeutic hypnosis, classical psychoanalysis, and psychotherapy. We then generalize a current evolutionary theory of sleep and dreaming, which focuses on the future, prospective memory system, to conceptualize a new evolutionary perspective on therapeutic hypnosis and brief psychotherapy. The implication of current neuroscience research is that activity-dependent gene expression and brain plasticity are the psychobiological basis of adaptive behavior, consciousness, and creativity in everyday life as well as psychotherapy. We summarize a case illustrating how this evolutionary perspective can be used to quickly resolve problems with past obstructive procrastination in school to facilitate current and future academic success.

The current investigation addresses the manner through which trauma affects basic memory and self-system processes. True and false recall for self-referent stimuli were assessed in conjunction with dissociative symptomatology among abused (N=76), neglected (N=92), and nonmaltreated (N=116) school-aged children. Abused, neglected, and nonmaltreated children did not differ in the level of processing self-schema effect or in the occurrence and frequency of false recall. Rather, differences in the affective valence of false recall emerged as a function of maltreatment subtype and age. Regarding dissociation, the abused children displayed higher levels of dissociative symptomatology than did the nonmaltreated children. Although abused, neglected, and nonmaltreated children did not exhibit differences in the valence of their self-schemas, positive and negative self-schemas were related to self-integration differently among the subgroups of maltreatment. Negative self-schemas were associated with increased dissociation among the abused children, whereas positive self-schemas were related to increased dissociation for the neglected children. Thus, positive self-schemas displayed by the younger neglected children were related to higher dissociation, suggestive of defensive self-processing. Implications for clinical intervention are underscored.

AIM: The Gudjonsson Suggestibility Scale (GSS) assesses suggestibility by asking respondents to recall a short story, followed by exposure to leading questions and pressure to change their responses. Suggestibility, as assessed by the GSS, appears to be elevated in people with intellectual disabilities (ID). This has been shown to reflect to some extent the fact that people with ID have poor recall of the story; however, there are discrepancies in this relationship. The aim of the present study was to investigate whether a closer match between memory and suggestibility would be found using a measure of recognition memory rather than free recall. METHOD: Three modifications to the procedure were presented to users of a learning disabilities day service. In all three experiments, a measure of forced-choice recognition memory was built into the suggestibility test. In experiments 1 and 2, the GSS was presented using either divided presentation (splitting the story into two halves, with memory and suggestibility tests after each half) or multiple presentation (the story was presented three times before presentation of the memory and suggestibility tests). Participants were tested twice, once with the standard version of the test and once with one of the modified versions. In experiment 3, an alternative suggestibility scale (ASS3) was created, based on real events in a learning disabilities day service. The ASS3 was presented to one group of participants who had been present at the events, and a second group who attended a different day service, to whom the events were unfamiliar. RESULTS: As observed previously, suggestibility was not closely related to free recall performance: recall was increased equally by all three manipulations, but they produced, respectively, no effect, a modest effect and a large effect on suggestibility. However, the effects on suggestibility were closely related to performance on the forced-choice recognition memory task: divided presentation of the GSS2 had no effect on either of these measures; multiple presentation of the GSS2 produced a modest increase in recognition memory and a modest decrease in suggestibility; and replacing the GSS with the ASS3 produced a large increase in recognition memory and a large decrease in suggestibility. IMPLICATIONS: The results support earlier findings that the GSS is likely to overestimate how suggestible a person will be in relation to a personally significant event. This reflects poor recognition memory for the material being tested, rather than increased suggestibility per se. People with ID may in fact be relatively non-suggestible for well-remembered events, which would include personally significant events, particularly those witnessed recently.

This study explores associations between language ability and hand preference in children with Down syndrome. Compared to typically developing children of the same age, children with Down syndrome showed weaker hand preference, were less consistent in the hand they used and also less willing to reach to extreme positions in contralateral space. Within the group of children with Down syndrome, those who showed a stronger or more consistent hand preference had better language and memory skills. This association could not be explained by differences in non-verbal cognitive ability or hearing loss. These findings are discussed within the theory of neurolinguistic development proposed by Locke [Locke (1997). Brain & Language, 58, 265-326].

The nocebo effect consists in delivering verbal suggestions of negative outcomes so that the subject expects clinical worsening. Here we show that nocebo suggestions, in which expectation of pain increase is induced, are capable of producing both hyperalgesic and allodynic responses. By extending previous findings on the placebo effect, we investigated the role of learning in the nocebo effect by means of a conditioning procedure. To do this, verbal suggestions of pain increase were given to healthy volunteers before administration of either tactile or low-intensity painful electrical stimuli. This nocebo procedure was also carried out after a pre-conditioning session in which two different conditioned visual stimuli were associated to either pain or no-pain. Pain perception was assessed by means of a Numerical Rating Scale raging from 0=tactile to 10=maximum imaginable pain. We found that verbal suggestions alone, without prior conditioning, turned tactile stimuli into pain as well as low-intensity painful stimuli into high-intensity pain. A conditioning procedure produced similar effects, without significant differences. Therefore, in contrast to placebo analgesia, whereby a conditioning procedure elicits larger effects compared to verbal suggestions alone, learning seems to be less important in nocebo hyperalgesia. Overall, these findings indicate that, by defining hyperalgesia as an increase in pain sensitivity and allodynia as the perception of pain in response to innocuous stimulation, nocebos can indeed produce both hyperalgesic and allodynic effects. These results also suggest that learning is not important in nocebo hyperalgesia compared to placebo analgesia.

This study examined how rumors originating in 3- to 6-year-olds' causal inferences can affect their own and their peers' memories for a personally experienced event. This was accomplished by exposing some members of classrooms to contextual clues that were designed to induce inferences about the causes of two unresolved components of the event. After a 1-week delay, a substantial number of children who were exposed to the clues misremembered their inferences as actual experiences. Causal inferential memory errors were most pronounced among 5- and 6-year-olds. Also, many of the children whose classmates were exposed to the clues mistakenly incorporated their classmates' causal inferences into their own accounts, with 3- and 4-year-olds being most likely to make this error.

Background: Dyslexia is a common learning difficulty affecting up to 10% of British children that is associated with a wide range of cognitive, emotional and physical symptoms. In the absence of effective conventional treatment, it is likely that parents will seek complementary and alternative medicine (CAM) to try and help their children. However, little is known about the level of CAM use or the type of CAM used by dyslexic children. Aims: This study assessed: (1) the lifetime use of CAM by dyslexic children, (2) the role of socio-demographic factors in CAM use by dyslexic children, (3) parental attitudes towards CAM use in the treatment of dyslexia, and (4) how parents' understanding of dyslexia affects CAM use. Methods & Procedures: A semi-structured questionnaire-based survey of parents of 148 dyslexic school children was undertaken. The children had been recruited to a university research programme investigating the effectiveness of a complementary therapy for the treatment of learning difficulties. Outcomes & Results: Lifetime use of CAM was 55.4% (82 children). The most popular CAM approaches were nutritional supplements/special diets (63 children) followed by homeopathy (29 children) and osteopathy/chiropractic manipulation (29 children). Socio-demographic factors did not predict CAM use. In total, parents of 101 dyslexic children reported that an interest in CAM for the treatment of dyslexia was based on their preference for CAM for their families more generally. Parents who thought that dyslexia was a 'medical/health' disorder were more likely to have used CAM with their children (p<0.01) than other parents in this survey. Conclusions & Implications: Educational and health professionals should be aware that many dyslexic children use CAM. Parents of dyslexic children should be provided with evidence-based advice to help them make informed therapeutic choices.

It is well established that source memory retrieval - remembering relationships between a core item and some additional attribute of an event - engages prefrontal cortex (PFC) more than simple item memory. In event-related potentials (ERPs), this is manifest in a late-onset difference over PFC between studied items which mandate retrieval of a second attribute, and unstudied items which can be immediately rejected. Although some sorts of attribute conjunctions are easier to remember than others, the role of source retrieval difficulty on prefrontal activity has received little attention. We examined memory for conjunctions of object shape and color when color was an integral part of the depicted object, and when monochrome objects were surrounded by colored frames. Source accuracy was reliably worse when shape and color were spatially separated, but prefrontal activity did not vary across the object-color and frame-color conditions. The insensitivity of prefrontal ERPs to this perceptual manipulation of difficulty stands in contrast to their sensitivity to encoding task: deliberate voluntary effort to integrate objects and colors during encoding reduced prefrontal activity during retrieval, but perceptual organization of stimuli did not. The amplitudes of ERPs over parietal cortex were larger for frame-color than object-color stimuli during both study and test phases of the memory task. Individual variability in parietal ERPs was strongly correlated with memory accuracy, which we suggest reflects a contribution of visual working memory to long-term memory. We discuss multiple bottlenecks for source memory performance.

A Survivor's Story

When Joe came into my office last February, he was very distraught. He had already failed the Bar once and his confidence was at an all time low. Each time he took a practice test, he would just freeze up. Joe had all of the classic symptoms of test anxiety. Since there were only two weeks left before the exam, I suggested we try a quick technique called anchoring. I assured Joe that with this simple tool, he could learn to instantly change his anxiety state into a more resourceful state in a matter of seconds. Joe picked an anchor (finger squeeze) that instantly transported him to a time in his past when he felt calm, collected and confident. Every time he fired off the anchor, he was able to quickly access those positive states. Armed with the right tools, Joe managed to tame his anxiety and pass the Bar! Just imagine having access to your most resourceful states - confidence, relaxation, focus, etc. - in a matter of moments. The tools are literally at your fingertips.

We explore a new distinction between the future, prospective memory system being investigated in current neuroscience and the past, retrospective memory system, which was the original theoretical foundation of therapeutic hypnosis, classical psychoanalysis, and psychotherapy. We then generalize a current evolutionary theory of sleep and dreaming, which focuses on the future, prospective memory system, to conceptualize a new evolutionary perspective on therapeutic hypnosis and brief psychotherapy. The implication of current neuroscience research is that activity-dependent gene expression and brain plasticity are the psychobiological basis of adaptive behavior, consciousness, and creativity in everyday life as well as psychotherapy. We summarize a case illustrating how this evolutionary perspective can be used to quickly resolve problems with past obstructive procrastination in school to facilitate current and future academic success.

Intelligence is primarily a measure in one's ability to learn. The underlying theory of intelligence presumes that there are individual differences in the capability to use perception, memory, and learning. This article addresses the relevance of intelligence testing, its proper use in society (to include academic endeavors), and the roles of Gardner's multi-intelligence theory in our societal functioning. Together I see these issues as having scientific, philosophical and even religious/spiritual dimensions. Other than the utility and morality issues, the concept of static versus dynamic/changing intelligence must be discussed.

This study examined age differences in children's vulnerability to be misled by two types of false overheard rumors, namely a rumor that suggested a reasonable explanation for an earlier unresolved experience and a rumor that suggested an explanation that conflicted with information already in memory. Results indicated that all of the children were highly susceptible to wrongly report the rumor as an actual experience when it merely filled a gap in memory. However, the 5- and 6-year-olds were better able than the 3- and 4-year-olds to resist the rumor when it suggested a conflicting explanation for a past event. Developmental changes in children's understanding of conflicting mental representations were linked to their ability to resist being misled by the conflicting rumor.

Every therapeutic strategy and system teach us the philosophy of the treatment system to the patient, but often this teaching is subliminal and the philosophical impact must be seen as "implanted philosophy", which gives distorted interpretations of past events called "implanted memories". Based on the understanding of the connection between "implanted memory" and "implanted philosophy" we have developed a strategy for avoiding implanting memories arising from one of the seven most common causes of implanted memories in psychodynamic therapy: 1) Satisfying own expectancies, 2) pleasing the therapist, 3) transferences and counter transferences, 4) as source of mental and emotional order, 5) as emotional defence, 6) as symbol and 7) from implanted philosophy. Freud taught us that child sexuality is "polymorphously perverted", meaning that all kinds of sexuality is present at least potentially with the little child; and in dreams consciousness often go back to the earlier stages of development, potentially causing all kinds of sexual dreams and fantasies, which can come up in therapy and look like real memories. The therapist working with psychodynamic psychotherapy, clinical holistic medicine, psychiatry, and emotionally oriented bodywork, should be aware of the danger of implanting philosophy and memories. Implanted memories and implanted philosophy must be carefully handled and de-learned before ending the therapy. In conclusion "clinical holistic medicine" has developed a strategy for avoiding implanting memories.

This study investigated the influence of hypnotic emotional inhibition on emotional response to and recall of emotional features of autobiographical memories. Twenty-nine high hypnotizable participants were administered a hypnotic induction and either emotional suppression or control instructions and then were asked to recall a personal distressing or neutral autobiographical memory. Dependent variables included self-reported emotion, EMG corrugator muscle activity, and use of affective descriptors in autobiographical memories. Participants in the suppression condition displayed less emotional responsivity on self-report and EMG corrugator muscle activity than other participants during recall of the distressing memory. In contrast, emotional suppression did not influence the use of affective descriptors in the content of personal memories. These findings point to the capacity for hypnotic emotional inhibition to differentially influence affective and semantic components of the emotional response.

Participants were administered a standard tape-recorded version of the Harvard Group Scale of Hypnotic Susceptibility, Form A (HGSHS:A) and then a modified version of the HGSHS:A response booklet that asked each participant to report which suggested behaviors they performed during the procedures. These response booklets were altered to include 3 additional suggestions not offered during the hypnotic procedures. Half the participants were administered the questions in the response booklet in the standard format ("I performed the suggested behavior" versus "I did not perform the suggested behavior"). The remaining participants were offered a third alternative to each question ("I do not remember this occurring"). As predicted, participants offered the 3rd alternative were significantly less likely to report performing actions that were never suggested during the procedures. Further, these participants reported performing fewer suggested behaviors (i.e., reported passing fewer of the true Harvard items) than participants in the standard 2-alternative condition.

Older adults' susceptibility to misinformation in an eyewitness memory paradigm was examined in two experiments. Experiment 1 showed that older adults are more susceptible to interfering misinformation than are younger adults on two different tests (old-new recognition and source monitoring). Experiment 2 examined the extent to which processes associated with frontal lobe functioning underlie older adults' source-monitoring difficulties. Older adults with lower frontal-lobe-functioning scores on neuropsychological tests were particularly susceptible to false memories in the misinformation paradigm. The authors' results agree with data from other false memory paradigms that show greater false recollections in older adults, especially in those who scored poorly on frontal tests. The results support a source-monitoring account of aging and illusory recollection.

Sixty-one participants from the community participated in a randomised controlled trial of group debriefing to assess the effect of this intervention upon memory for a stressful event. Participants were randomly allocated to one of three groups: debriefing; debriefing with an experimenter confederate present (who supplied three pieces of misinformation to the group regarding the stressful event); and a no-treatment control. All groups were shown a very stressful video and were again reviewed after 1 month. Members of the debriefing group where a confederate provided misinformation were more likely to recall this misinformation as fact than members of the other two groups. The debriefing group was also more accurate in their recall of peripheral content than the confederate group. Across all groups, participants were found to be more accurate at central rather than peripheral recall yet more confident for incorrect memories of the video than correct memories.
