Neuroimaging data indicate that episodic memory (i.e., remembering specific past experiences) and episodic simulation (i.e., imagining specific future experiences) are associated with enhanced activity in a common set of neural regions, often referred to as the core network. This network comprises the hippocampus, parahippocampal cortex, lateral and medial parietal cortex, lateral temporal cortex, and medial prefrontal cortex. Evidence for a core network has been taken as support for the idea that episodic memory and episodic simulation are supported by common processes...

Trip Gabriel
In this vivid first-person case history, political reporter Trip Gabriel describes experiencing a classic episode of transient global amnesia. He was near the average target age of 61. Although no cause has been established for the syndrome, as with many other patients his episode appears to have been triggered by contact with water: He was racing a sailboat. While remaining alert and handling complex sailing maneuvers, he suddenly developed amnesia that left him with no recollection of finishing two races, returning to shore, drinking a beer with his friends, needing help finding his car, and not knowing where he was or where he lived...

The hippocampus plays a prominent role in associative memory by supporting relational binding and recollection processes. Structural atrophy in the hippocampus is likely to induce associative memory deficits in older adults. Previous studies have primarily focused on average age-related differences in hippocampal structure and memory performance. To date, however, it remains unclear whether individual differences in hippocampal morphometry underlie differential associative memory performance, and whether there are sex differences in the structural correlates of associative memory in healthy older adults...

The adaptive view of human memory (Nairne, 2010) assumes that animates (e.g., rabbit) are remembered better than inanimates (e.g., glass) because animates are ultimately more important for fitness than inanimates. Previous studies provided evidence for this view by showing that animates were recalled or recognized better than inanimates (e.g., Nairne, VanArsdall, Pandeirada, Cogdill, & LeBreton, 2013), but they did not assess memory for contextual details (e.g., where animates vs. inanimates occurred). In this study, we tested recollection of spatial information (Study 1) and temporal information (Study 2) associated with animate versus inanimate words...

It has been postulated that memories of near-death experiences (NDEs) could be (at least in part) reconstructions based on experiencers' (NDErs) previous knowledge and could be built as a result of the individual's attempt to interpret the confusing experience. From the point of view of the experiencer, NDE memories are perceived as being unrivalled memories due to its associated rich phenomenology. However, the scientific literature devoted to the cognitive functioning of NDErs in general, and their memory performance in particular, is rather limited...

Timm Rosburg, Axel Mecklinger
In event-related potential (ERP) studies, the left-parietal old/new effect is commonly considered as a neural correlate of recollection. In memory exclusion tasks, the effect is usually observed when the targeted information is identified, but it is not necessarily present when studied items are rejected as nontargets. Interestingly, both the presence and the absence of such old/new effects to nontargets have been regarded as indicator for strategic retrieval. We reviewed previous ERP studies using memory exclusion tasks to analyze the reaction time (RT) pattern in such studies, as well as the influence of task difficulty on the occurrence of nontarget retrieval...

BACKGROUND: Simulation education is an important part of health care education and training. There is growing evidence to support the usefulness of simulation, especially in training for infrequently occurring situations, such as medical emergencies seen by dental practitioners. There are, however, few data on the longer term effects of simulation, including usefulness, relevance, emotional effect and ability to affect changes to daily practice. METHODS: Dentists and dental nurses who had undergone simulation training in medical emergencies for dental sedation practitioners undertook a semi-structured interview about their perception of the simulation experience...

Talat Demirsöz, H Belgin Ayvaşık
OBJECTIVE: Recent literature proposes that repeated checking increases familiarity with the material, making recollections less vivid and detailed and promoting distrust in memory. The aim of the current study is to investigate the possible underlying mechanisms of low confidence in memory. METHOD: The Padua Inventory-Washington State University Revision (PI-WSUR) was applied in a cohort of university students. Among the students who completed the PI-WSUR, 84 participants were selected and assigned to low Obsessive-Compulsive Symptomatology (OCS) group or high OCS group according to their PI-WSUR scores...

Rita R Silva, Teresa Garcia-Marques, Rolf Reber
We contrast the effects of conceptual and perceptual fluency resulting from repetition in the truth effect. In Experiment 1, participants judged either verbatim or paraphrased repetitions, which reduce perceptual similarity to original statements. Judgments were made either immediately after the first exposure to the statements or after one week. Illusions of truth emerged for both types of repetition, with delay reducing both effects. In Experiment 2, participants judged verbatim and paraphrased repetitions with either the same or a contradictory meaning of original statements...

Hierarchical control of skilled performance depends on chunking of several lower-level units into a single higher-level unit. The present study examined the relationship between chunking and recognition of trained materials in the context of typewriting. In 3 experiments, participants were trained with typing nonwords and were later tested on their recognition of the trained materials. In Experiment 1, participants typed the same words or nonwords in 5 consecutive trials while performing a concurrent memory task...

BACKGROUND: The future of notifiable condition reporting in the United States is undergoing a transformation with the increasing development of Health Information Exchanges which support electronic data-sharing and -transfer networks and the wider adoption of electronic laboratory reporting. Communicable disease report forms originating in clinics are an important source of surveillance data for public health agencies. However, problems of poor data quality and delayed submission of reports to public health agencies are common...

BACKGROUND: Lesions of the angular gyrus (AnG) region of human parietal cortex do not cause amnesia, but appear to be associated with reduction in the ability to consciously experience the reliving of previous events. OBJECTIVES/HYPOTHESIS: We used continuous theta burst stimulation to test the hypothesis that the cognitive mechanism implicated in this memory deficit might be the integration of retrieved sensory event features into a coherent multimodal memory representation...

Episodic memory has been tested in non-human animals using depletion paradigms that assess recollection for the "what", "where" and "when" (i.e., how long ago). This paradigm has not been used with human children, yet doing so would provide another means to explore their episodic memory development. Using a depletion paradigm, preschool-aged children were presented in two trials with a preferred food that was only edible after a short interval and a less-preferred food that was edible after the short and long intervals...

Choice blindness is the failure to detect a discrepancy between a choice and its outcome. The misinformation effect occurs when the recollection of an event changes because new, misleading information about the event is received. The purpose of this study was to merge the choice blindness and misinformation effect paradigms, and thus examine whether choice blindness can be created for individuals' recollections of a witnessed event, and whether this will affect their later recollections of the event. Thus, as a way of delivering misinformation the participants ostensibly became their own source of the misleading information...

The present study aimed to examine the perceptions of African American communities regarding the involvement of political leaders in facilitating policy and environmental change promoting healthy eating and physical activity. We selected the Metro Jackson Area comprised of Hinds, Madison and Rankin Counties because it is a combination of urban and rural communities. The sample consisted of 70 participants from seven sites. A total of seven focus groups were asked to respond to one question to assess political leaders' involvement in healthy living: "When you think about your political leaders that you have in the Jackson, Mississippi area, do any of them promote healthy eating and physical activity?" Focus groups consisted of six to 12 participants and were asked to comment on their participation in physical activity...

BACKGROUND: Approximately half of trauma patients develop post-traumatic depression. It is suggested that beta-blockade impairs trauma memory recollection, reducing depressive symptoms. This study investigates the effect of early beta-blockade on depression following severe traumatic injuries in patients without significant brain injury. METHODS: Patients were identified by retrospectively reviewing the trauma registry at an urban university hospital between 2007 and 2011...

Chris Tailby, Genevieve Rayner, Sarah Wilson, Graeme Jackson
Higher cognitive functions depend upon dynamically unfolding brain network interactions. Autobiographical recollection - the autonoetic re-experiencing of context rich, emotionally laden, personally experienced episodes - is an excellent example of such a process. Autobiographical recollection unfolds over time, with different cognitive processes engaged at different times throughout. In this paper we apply a recently developed analysis technique - event related independent components analysis (eICA) - to study the spatiotemporal dynamics of neural activity supporting autobiographical recollection...

We report 4 experiments investigating auditory hindsight bias-the tendency to overestimate the intelligibility of distorted auditory stimuli after learning their identity. An associative priming manipulation was used to vary the amount of processing fluency independently of prior target knowledge. For hypothetical designs, in which hindsight judgments are made for peers in foresight, we predicted that judgments would be based on processing fluency and that hindsight bias would be greater in the unrelated- compared to related-prime context (differential-fluency hypothesis)...

REVIEW
Bruce J Kimura
The development of hand-carried, battery-powered ultrasound devices has created a new practice in ultrasound diagnostic imaging, called 'point-of-care' ultrasound (POCUS). Capitalising on device portability, POCUS is marked by brief and limited ultrasound imaging performed by the physician at the bedside to increase diagnostic accuracy and expediency. The natural evolution of POCUS techniques in general medicine, particularly with pocket-sized devices, may be in the development of a basic ultrasound examination similar to the use of the binaural stethoscope...
