Body posture facilitates retrieval of autobiographical memories.

We assessed potential facilitation of congruent body posture on access to and retention of autobiographical memories in younger and older adults. Response times were shorter when body positions during prompted retrieval of autobiographical events were similar to the body positions in the original events than when body position was incongruent. Free recall of the autobiographical events two weeks later was also better for congruent-posture than for incongruent-posture memories. The findings were similar for younger and older adults, except for the finding that free recall was more accurate in younger adults than in older adults in the congruent condition. We discuss these findings in the context of theories of embodied cognition.

Asymptotic learning of alphanumeric coding in autobiographical memory.

Studies of autobiographical memory have shown that observed levels of incidental learning are often relatively low. Do low levels of retention result simply from a low learning rate, or is learning also asymptotic? To address this question, it is necessary to trace performance over a large number of learning opportunities, and this was carried out in the context of the recent development of widespread texting behaviour. It was found that memory for the alphanumeric layout of a phone improved as a function of sending approximately the first 500 texts, but then the improvement stopped. The incidence of memory error was incompatible with a simple power-law relation but was modelled closely by an asymptotic relation. It is suggested that this pattern reflects a movement towards automaticity in the primary task which progressively closes down the possibility that incidental learning can occur.

Episodic autobiographical memory in depression: Specificity, autonoetic consciousness, and self-perspective.

Autobiographical memory (AM) and the self are closely linked. AM retrieval in depression is characterized by a lack of specificity, suggesting an impairment of episodic AM. Autonoetic consciousness and self-perspective, which are critical to episodic AM, have never been addressed in depression. Twenty-one depressed inpatients and 21 matched controls were given an episodic AM task designed to assess positive and negative memories regarding specificity, autonoetic consciousness (remember/know procedure), and self-perspective (field/observer procedure). For specificity, "remember", and "field" responses, ANOVAs revealed a main group effect and a group x valence interaction. Between groups, patients showed lower scores than controls for positive memories. Within groups, patients showed greater scores for negative memories, and controls showed greater scores for positive memories. There is a global episodic AM impairment of positive memories in depression regarding specificity, autonoetic consciousness, and self-perspective. Our results suggest new cognitive interventions to improve the self-relevance of positive memories in depression.

Do school-age children remember or know the personal past?

The aim of this study was to examine developmental differences in autobiographical memory using a novel test that assesses its semantic and episodic subcomponents. Forty-two children aged 7-13 years were asked to recall semantic information and episodic events from three different time periods (current school year, last school year, and previous school years). For the recalls of all events, sense of remembering or sense of just knowing was measured via the Remember/Know paradigm. Age-related differences were observed for episodic autobiographical memory whereas semantic autobiographical memory was characterized by a relative developmental invariance. The increase with age was also found in the number of "Remember" responses and their justification in terms of the actual contextual information retrieved-factual, spatial, and, more especially, temporal details. These findings highlight developmental differences between the episodic and semantic subcomponents of autobiographical memory and support the view that mental 'time travel' through subjective time, which allows one to re-experience the past through self-awareness, is the last feature of autobiographical memory to become fully operational.

Information-processing bias in social phobia.

Social phobia is a persistent disorder that is unlikely to be maintained by avoidance alone. One reason for the enduring nature of social phobia may be the way individuals with the disorder process social information. It is important for those involved in social phobia to have an understanding of information-processing biases, because it has the potential to guide psychological interventions. In this review of social phobia, probability and cost estimates of social situations are examined, interpretive biases are evaluated and findings relating to memory and negative imagery are also reviewed. The clinical implications of social-phobia-related information-processing biases are discussed and possible avenues for future research are outlined.

Cognitions in cognitive-behavioral psychotherapies; toward an integrative model.

There seems to be a lack of a coherent and integrative theory and theoretically informed manuals in cognitive behavioral therapies that could negatively impact both the program of CBT as a platform for psychotherapy integration, as well as its efficacy and effectiveness. Although CBT is the golden psychological treatment for various disorders, overall, about 30-40% of the patients are still non-responsive to these interventions and various schools debate their status as promoters of the best theoretical view. The objective of the present paper is to use cognitive psychology/science as a tool to clarify several theoretical confusions in CBT, with impact on a coherent science and practice of CBT. As a general conclusion, we believe that CBT has reached preeminence in the clinical field betting on cold cognitions. Despite obvious advantages and accomplishments, this approach seems to loose its heuristic value. We believe that the next phase of CBT development lies in the construct of hot cognitions (which would increase its effectiveness) and in cognitive psychology (which would contribute to a coherent science of CBT beyond various schools). These developments could offer CBT the chance to be a platform for the integration of psychotherapy.

The contribution of "All Quiet on the Western Front" to our understanding of psychological trauma.

The most effective way of coping with a traumatic event is to develop a narrative, which can take many forms, e.g., talking to friends and family, formal treatment, written accounts. Autobiographical works and novels by ex-soldiers are good examples of texts, which can aid psychologists' understanding of traumatic stress, providing powerful insights not normally obtained through traditional psychological methods. Remarque's "All Quiet on the Western Front" illustrates the psychological problems experienced by men in battle. Psychologists have rarely used novels as sources of data, yet they provide a rich insight into the problems associated with traumatic events. The issues raised in the book include: an account of battle experience, civilian understanding, memory and coping. This approach can be used to extend our understanding of traumatic situations.

Reduced specificity of autobiographical memory: a mediator between rumination and ineffective social problem-solving in major depression?

BACKGROUND: Depressed individuals display a deficit in effectively solving social problem situations (e.g., []). Recent research suggests that rumination may interfere with such effective problem-solving (e.g., []). However, little is known, as yet, about the mechanisms that are underlying this relation between rumination and poor problem-solving. The present study investigated the role of reduced specificity of autobiographical memories as a mediator of this relationship. METHODS: 24 depressed patients (15 women) completed the Autobiographical Memory Test (AMT), the Means-Ends Problem-Solving Task (MEPS), the Ruminative Response Scale (RRS) and the Rumination on Sadness Scale (RSS). RESULTS: Consistent with previous studies, rumination, ineffective problem-solving and reduced memory specificity were significantly associated. Regression analyses further extended these findings by showing that reduced memory specificity mediated the association between rumination and problem-solving effectiveness. LIMITATIONS: The correlational nature of this study limits to some extent the conclusions that can be drawn on the directionality of the observed relationships. CONCLUSIONS: Results offer support for the idea that lack of autobiographical memory specificity mediates the known relationship between rumination and poor problem-solving.

Self-report by elderly breast cancer patients was an acceptable alternative to surveillance, epidemiology, and end results (SEER) abstract data.

BACKGROUND AND OBJECTIVES: The purpose of this study was to compare breast cancer patients' self-report and surveillance, epidemiology, and end results (SEER) abstract data regarding type of treatment received (radiation, chemotherapy, and hormonal therapies). METHODS AND DESIGN: Patients 65 years of age or older diagnosed during 1999-2001 with stage I-II breast cancer and treated with conserving surgery were identified from the Iowa SEER registry; 307 (41% of those eligible) completed telephone interviews. SEER-registry abstract data also were obtained. RESULTS: Agreement between self-reports and SEER data varied by type of treatment, with almost perfect agreement for chemotherapy (kappa = 0.93) and moderate to substantial agreement for ever use of hormonal therapy (kappa = 0.61), receipt of radiation therapy (kappa = 0.60), and current use of hormonal therapy (kappa = 0.54). If the SEER data are assumed to be the "gold standard," the sensitivity was generally high (>87%) for all types of treatment. Specificity varied according to type of treatment: highest for chemotherapy (98.4%) and lowest for radiation therapy (49.0%). Predictive values positive and negative were above 75% across type of treatment. CONCLUSION: Using self-reported data was an acceptable alternative to reviewing medical records for documenting some types of breast cancer treatment.

Autobiographical memory deficit in anorexia nervosa: emotion regulation and effect of duration of illness.

Emotional deficits in anorexia nervosa can be expressed in autobiographical memory recall. The aim of this study is to test whether deficits in autobiographical memory exist in anorexic patients and concern specifically negative or positive emotional valence. Moreover, it is unclear whether these deficits are dependent upon comorbid aspects (depression, alexithymia, and anxiety) or upon illness duration. Anorexic patients (n=25) were compared to healthy volunteers based on their clinical assessment, explicit memory test score, and autobiographical memory test score. The study makes use of the autobiographical test of Williams and Scott, which involves specific emotional cues to elicit memory. Anorexic patients recalled more general memories than controls in autobiographical memory test, but had no deficit in explicit memory test. This pattern, observed both for negative and positive cues, was neither related to depression or alexithymia, nor to anxiety severity, but increased significantly with illness duration. These results show that anorexic patients are characterized by relative difficulty in the integration of both negative and positive emotional experiences, and that this impairment is reinforced by illness duration.

A personal experience with coronary artery bypass grafting, carotid patching, and other factors influencing the outcome of carotid endarterectomy.

OBJECTIVE: This study was conducted to investigate the influence of coronary artery bypass grafting (CABG), carotid patching, and other factors on the outcome of all carotid endarterectomies (CEAs) performed by a single surgeon at a tertiary referral center. METHODS: The series includes 2262 CEAs (335 bilateral) in 1521 men and 741 women (33%) with median ages of 66 and 68 years, respectively. Surgical indications were asymptomatic stenosis for 1503 procedures (66%), retinal ischemia or cerebral transient ischemic attacks each for 271 (12%), and prior stroke for 217 (9.6%). CEA was done as an isolated operation in 1959 patients and was performed in conjunction with simultaneous CABG in 303 (13%). Primary arteriotomy closure was used for 783 CEAs (35%), vein patching for 1232 (54%), and synthetic patching for 247 (11%). Outcome event rates were assessed by logistic regression analysis, proportional hazards models, and Kaplan-Meier estimations. RESULTS: Postoperative mortality (odds ratio [OR], 3.5; 95% confidence interval [CI], 1.7 to 7.5; P = .001), stroke (OR, 3.2; 95% CI, 1.6 to 6.4; P = .001), and combined stroke and mortality rates (OR, 3.4; 95% CI, 2.0 to 5.8; P < .001) were significantly higher for simultaneous CEA/CABG than for isolated CEA. Ipsilateral postoperative stroke rates were similar (2.6% vs 1.7%, P = .41) in both settings. Vein patching had a lower risk for ipsilateral stroke (OR, 0.42; 95% CI, 0.21 to 0.86; P = .015) than primary closure, but was not significantly different from synthetic patching (P = .10). The documented incidence of postoperative carotid thrombosis was 1.5% with primary closure, 0.6% with vein patching, and 2.0% with synthetic patching (P = .088). Overall Kaplan-Meier survival was 92% at 1 year, 71% at 5 years, 41% at 10 years, and 20% at 15 years, but long-term mortality rates were higher after simultaneous CEA/CABG (hazard ratio, 1.3; 95% CI, 1.1 to 1.5; P = .002) than after CEA alone. Late strokes or retinal infarctions have been reported after 97 (5.0%) of the 1923 operations for which follow-up was available, 51 (2.3%) of which were ipsilateral to CEA. The incidence of > or = 60% recurrent stenosis was independently influenced by carotid patching (OR, 0.61; 95% CI, 0.40 to 0.92; P = .019) but not by the choice of patch material (P = .11). CONCLUSIONS: These results substantiate the common observation that patients who require simultaneous CEA/CABG have a higher risk for adverse outcomes than patients who undergo isolated CEA. Carotid patching provided significant benefit with respect to the risks for ipsilateral postoperative stroke and > or = 60% recurrent stenosis.

Perceptions of student nurses regarding the use of a popular autobiography as a teaching tool.

Recent studies encourage educators in nursing to use innovative and non-traditional teaching methods, such as using popular movies, posters, portfolios and surfing the internet, to stimulate students' interest, participation and interaction to enhance academic performance as well as knowledge retention. In this, descriptive cross-sectional study, we used self-administered questionnaires with statements graded on 5-points Likert scale (quantitative measures) and open-ended questions (qualitative measures), to assess the feasibility and students' perceptions regarding the use of Lance Armstrong's autobiography of surviving against cancer as a teaching tool. At the beginning of the lecture copies of selected chapters from: "It's Not About the Bike; My Journey Back to Life" [Armstrong, L., Jenkins, S. 2001. It's Not About The Bike: My Journey Back To Life. Yellow Jersey Press, Random House (Pty) Limited, Great Britain], were given to students. Willing students were requested to read for the whole class while the lecturer interjected periodically to explain and expound on certain pharmacological concepts. Eighty percent (80%) of participants felt that the use of an autobiography stimulated their interesting in cancer drugs and 84% agreed/strongly agreed that it contributed to their knowledge of pharmacology. Using Lance Armstrong's autobiography of survival to teach cytotoxic drugs is a worthwhile and rewarding exercise from the student nurses' perspective.

Re-experiencing old memories via hippocampus: a PET study of autobiographical memory.

The time-scale of medial temporal lobe (MTL) involvement in storage and retrieval of episodic memory is keenly debated. To test competitive theories of long-term memory consolidation, the present work aimed at characterizing which cerebral regions are involved during retrieval of recent and remote strictly episodic autobiographical memory. Using positron emission tomography (PET), we examined mental retrieval of recent (0-1 year) and remote (5-10 years) autobiographical memories, controlling for the nature of the autobiographical memories (i.e., specificity, state of consciousness, vividness of mental visual imagery, emotion) retrieved during scanning by behavioral measures assessed at debriefing for each event recalled. Cognitive results showed that specificity and emotion did not change with time interval although both autonoetic consciousness and mental image quality were significantly higher for recent memories, suggesting an underlying shift in the phenomenal experience of remembering with the passage of time. The SPM analysis revealed common activations during the recollection of recent and remote memories that involved a widespread but mainly left-sided cerebral network, consistent with previous studies. Subtraction analysis demonstrated that the retrieval of recent (relative to remote) autobiographical memories principally activated the left dorsolateral prefrontal cortex whereas the retrieval of remote (relative to recent) autobiographical memories activated the inferior parietal cortex bilaterally. ROIs analysis revealed more hippocampal activity for remote memories than for recent ones and a preferentially right-sided involvement of the hippocampal responses whatever the remoteness of autobiographical memories. New insights based on higher hippocampal response to the remoteness of episodic autobiographical memories challenge the standard model and are less discrepant with the multiple trace theory.

Intentional false responding shares neural substrates with response conflict and cognitive control.

The ability to deceive others is a high-level social and cognitive function. It has been suggested that response conflict and cognitive control increase during deceptive acts but this hypothesis has not been evaluated directly. Using fMRI, we tested this prediction for the execution of an intentional false response. Subjects were instructed to respond truthfully or falsely to a series of yes/no questions that were also varied in autobiographical and nonautobiographical content to further examine the influence of personal relevance when lying. We observed an interference effect (longer reaction times for false versus true responses) that was accompanied by increased activation within the anterior cingulate, caudate and thalamic nuclei, and dorsolateral prefrontal cortex (DLPFC), a circuit that has been implicated in response conflict and cognitive control. Behavioral and neural effects were more robust when falsifying autobiographical responses relative to nonautobiographical responses. Furthermore, a correlation between reaction time and left caudate activity supported the presence of increased response inhibition when falsifying responses. When presented with self-relevant (autobiographical) stimuli regardless of response condition, the mesial prefrontal and posterior cingulate cortices were recruited. Neural activity within these two regions and the anterior cingulate cortex (ACC) also showed correlations with self-report personality measures from the Psychopathic Personality Inventory (PPI). Overall, we conclude that the process of interference is inherent to the act of falsifying information and that the amount of conflict induced and cognitive control needed to successfully execute false responses is greater when dealing with personal information.

Ecphory of autobiographical memories: an fMRI study of recent and remote memory retrieval.

Ecphory occurs when one recollects a past event cued by a trigger, such as a picture, odor, or name. It is a central component of autobiographical memory, which allows us to "travel mentally back in time" and re-experience specific events from our personal past. Using fMRI and focusing on the role of medial temporal lobe (MTL) structures, we investigated the brain bases of autobiographical memory and whether they change with the age of memories. Importantly, we used an ecphory task in which the remote character of the memories was ensured. The results showed that a large bilateral network supports autobiographical memory: temporal lobe, temporo-parieto-occipital junction, dorsal prefrontal cortex, medial frontal cortex, retrosplenial cortex and surrounding areas, and MTL structures. This network, including MTL structures, changed little with the age of the memories.

Autobiographical memory in semantic dementia: implication for theories of limbic-neocortical interaction in remote memory.

We examined autobiographical memory performance in two patients with semantic dementia using a novel measure, the Autobiographical Interview [Levine, Svoboda, Hay, Winocur, & Moscovitch (2002). Aging and autobiographical memory: Dissociating episodic from semantic retrieval. Psychology and Aging, 17, 677-689], that is capable of dissociating episodic and personal semantic recall under varying levels of retrieval support. Earlier reports indicated that patients with semantic dementia demonstrate autobiographical episodic memory loss following a "reverse gradient" by which recent memories are preserved relative to remote memories. We found limited evidence for this pattern at conditions of low retrieval support. When structured probing was provided, patients' autobiographical memory performance was similar to that of controls. Retesting of one patient after 1 year indicated that retrieval support was insufficient to bolster performance following progressive prefrontal volume loss, as documented with quantified structural neuroimaging. These findings are discussed in relation to theories of limbic-neocortical interaction in autobiographical memory.

The functional neuroanatomy of autobiographical memory: a meta-analysis.

Autobiographical memory (AM) entails a complex set of operations, including episodic memory, self-reflection, emotion, visual imagery, attention, executive functions, and semantic processes. The heterogeneous nature of AM poses significant challenges in capturing its behavioral and neuroanatomical correlates. Investigators have recently turned their attention to the functional neuroanatomy of AM. We used the effect-location method of meta-analysis to analyze data from 24 functional imaging studies of AM. The results indicated a core neural network of left-lateralized regions, including the medial and ventrolateral prefrontal, medial and lateral temporal and retrosplenial/posterior cingulate cortices, the temporoparietal junction and the cerebellum. Secondary and tertiary regions, less frequently reported in imaging studies of AM, are also identified. We examined the neural correlates of putative component processes in AM, including, executive functions, self-reflection, episodic remembering and visuospatial processing. We also separately analyzed the effect of select variables on the AM network across individual studies, including memory age, qualitative factors (personal significance, level of detail and vividness), semantic and emotional content, and the effect of reference conditions. We found that memory age effects on medial temporal lobe structures may be modulated by qualitative aspects of memory. Studies using rest as a control task masked process-specific components of the AM neural network. Our findings support a neural distinction between episodic and semantic memory in AM. Finally, emotional events produced a shift in lateralization of the AM network with activation observed in emotion-centered regions and deactivation (or lack of activation) observed in regions associated with cognitive processes.

Remembering the past and imagining the future: common and distinct neural substrates during event construction and elaboration.

People can consciously re-experience past events and pre-experience possible future events. This fMRI study examined the neural regions mediating the construction and elaboration of past and future events. Participants were cued with a noun for 20s and instructed to construct a past or future event within a specified time period (week, year, 5-20 years). Once participants had the event in mind, they made a button press and for the remainder of the 20s elaborated on the event. Importantly, all events generated were episodic and did not differ on a number of phenomenological qualities (detail, emotionality, personal significance, field/observer perspective). Conjunction analyses indicated the left hippocampus was commonly engaged by past and future event construction, along with posterior visuospatial regions, but considerable neural differentiation was also observed during the construction phase. Future events recruited regions involved in prospective thinking and generation processes, specifically right frontopolar cortex and left ventrolateral prefrontal cortex, respectively. Furthermore, future event construction uniquely engaged the right hippocampus, possibly as a response to the novelty of these events. In contrast to the construction phase, elaboration was characterized by remarkable overlap in regions comprising the autobiographical memory retrieval network, attributable to the common processes engaged during elaboration, including self-referential processing, contextual and episodic imagery. This striking neural overlap is consistent with findings that amnesic patients exhibit deficits in both past and future thinking, and confirms that the episodic system contributes importantly to imagining the future.
