Emotion may influence memory both by altering attention and perception during encoding and by affecting memory retention. To date, studies have focused on the enhancement of memory consolidation by arousal. However, they have failed to rule out a role for attention. To specifically link memory enhancement of arousing material to modulation of memory retention, we examined recognition of neutral and arousing words at two time points and under conditions that manipulate attention during encoding. Participants were briefly presented with an arousing or neutral word at the periphery, while fixating on a central word. Recognition of peripheral words was assessed either immediately or after 24 h. Whereas recognition of neutral words became worse over time, recognition of arousing words remained the same and was better than neutral word recognition at delay. The results indicate that arousal supports slower forgetting even when the difference in attentional resources allocated to stimuli is minimized.

We propose a method that combines adaptive autoregressive (AAR) identification and spectral power decomposition for the study of movement-related spectral changes in scalp EEG signals and basal ganglia local field potentials (LFPs). This approach introduces the concept of movement-related poles, allowing one to study not only the classical event-related desynchronizations (ERD) and synchronizations (ERS), which correspond to modulations of power, but also event-related modulations of frequency. We applied the method to analyze movement-related EEG signals and LFPs contemporarily recorded from the sensorimotor cortex, the globus pallidus internus (GPi) and the subthalamic nucleus (STN) in a patient with Parkinson's disease who underwent stereotactic neurosurgery for the implant of deep brain stimulation (DBS) electrodes. In the AAR identification we compared the whale and the exponential forgetting factors, showing that the whale forgetting provides a better disturbance rejection and it is therefore more suitable to investigate movement-related brain activity. Movement-related power modulations were consistent with previous studies. In addition, movement-related frequency modulations were observed from both scalp EEG signals and basal ganglia LFPs. The method therefore represents an effective approach to the study of movement-related brain activity.

Based on anthropological field research (1997-2000) within the Department of Health and Community Services in the Northern Territory in Australia, this paper explores the lingering features of colonial logic in the pastoral work of public health workers in the Northern Territory of Australia. The public health professionals drawn to work in this space are determined to remedy what is wrong with culturally acceptable solutions. But viewed from an anthropological perspective, the way in which health professionals conceptualise the problems they need to solve ultimately serves to reinforce the reality of the need for their continued tutelary presence. This paper aims to draw out the complex ways in which this interventionary effect is secured, concentrating in particular on the role played by progressive ideologies of participatory development and information sharing. It argues that through a complex process of forgetting, the otherwise innocuous gestures of public health goodwill recreate a mandate for more public health intervention. This is not a simple moral tale where analysts can easily identify good and bad practices and thus distance themselves from the difficulties involved. Rather, by emphasising the honest commitments to improvement in situations of mass illness and preventable disease that health professionals bring to their work, and the burden they bear in being conscious of the recent colonial past, the paper aims to avoid the judgement that this sort of work is easy to get right.

Recent research has indicated a link between retrieval-induced forgetting and the production of misinformation effects (J. Saunders & M. D. MacLeod, 2002). The mechanism underlying this relationship, however, remains unclear. In an attempt to clarify this issue, the authors presented 150 participants with misinformation under conditions designed to promote the activation of inhibitory control during the retrieval of information about a target event. A modified retrieval practice paradigm that used the independent probe method pioneered by M. C. Anderson and B. A. Spellman (1995) revealed that misinformation effects emerged only where misinformation had been introduced about items that had been subject to 1st-order, 2nd-order, or cross-category inhibition. By contrast, misinformation effects failed to emerge where inhibitory processing had not been activated. These findings are discussed in terms of inhibitory control, memory malleability, and their implications for the interviewing of eyewitnesses.

To assess the prevalence and some potential correlates of non-adherence to medications in adolescent and young adult transplant patients. Fifty patients who had undergone heart or heart-lung transplantation 1.4-14.9 yr (mean 8.8 yr) previously completed the Beliefs about Medication Questionnaire (BMQ), Perceived Illness Experience (PIE) scale and a demographics questionnaire. Medical notes were reviewed for information regarding previous psychiatric referral, rejection episodes and complications and noted concerns about adherence. Forty (80%) completed questionnaires were received. Non-adherence determined from the questionnaires was associated with forgetting to take medication and was classified as unintentional non-adherence. Such non-adherence was reported by 11 (28%) patients. Seven patients (18%) showed evidence from their records of deliberate non-adherence, which was classified as intentional. Whilst intentional non-adherence was associated with depression and transplant-related lymphoma, unintentional non-adherence and perceived difficulties with medications were associated with high scores on the PIE preoccupation with illness and BMQ concerns subscale and with drinking alcohol. Future research is required to determine whether unintentional non-adherence results in significant medical complications in the longer term and how a reduction in the prevalence of non-adherence can be facilitated.

Recent data (T. J. Perfect, C. J. A. Moulin, M. A. Conway, & E. Perry, 2002) have suggested that retrieval-induced forgetting (RIF) depends on conceptual memory because the effect is not found in perceptually driven tasks. In 3 experiments, the authors aimed to show that the presence of RIF depends on whether the procedure induces appropriate transfer between representations and competition rather than on the nature of the final test. The authors adapted the standard paradigm to introduce lexical categories (words that shared the first 2 letters) at study and practice. Direct and indirect fragment completion tests were used at retrieval. The results showed significant RIF effects in perceptually driven tasks. Furthermore, they indicated that the presence of RIF effects depended on using adequate cuing to induce competition during the retrieval practice and on the final memory test tapping the inhibited representation.

Many asthma patients use the emergency department (ED) as the sole source of asthma care. This is considered inadequate and poor practice. This prospective study revealed that young age, lack of evening clinic, forgetting to keep the appointment, conflicting priorities of daily life, and easy access to the ED on an as-needed basis for urgent care, medications, and prescriptions, and failure to use inhaled corticosteroids were significant while lack of insurance or access to asthma clinic were not significant factors in exclusive use of the ED. Establishing ED asthma education programs or an after hours asthma clinic may alleviate the practice.

The association between obstetric pain relief and long-term memory of pain is poorly researched in spite of the fact that a woman's memory of childbirth may affect her emotional wellbeing and future reproduction. The aim of this study was to investigate the association between epidural analgesia and other forms of pain relief, and memory of pain at two months and one year after birth. A national sample of 2482 Swedish speaking women with vaginal delivery or emergency cesarean section preceded by labor were followed from early pregnancy to one year after birth. Data were collected by three postal questionnaires: in early pregnancy, and two months and one year after the birth. Recollection of intense pain at two months and one year was associated with high rates of pain relief, and this was most obvious regarding epidural analgesia in first-time mothers. When comparing women with the same pain score at two months postpartum who had and who did not have an epidural, the first group seemed to have greater difficulty forgetting pain 10 months later. Possible explanations of these findings are discussed.

We investigated recall of line-drawing pictures paired at study with an instruction either to remember (TBR items) or to forget (TBF items). Across three 7-minute tests, net recall (items reported independent of accuracy in instructional designation) and correctly classified recall (recall conditional on correct instructional designation) showed directed forgetting. That is, for both measures, recall of TBR items always exceeded recall of TBF items. Net recall for both item types increased across tests at comparable levels showing hypermnesia. However, across tests, correct classification of both item types decreased at comparable levels. Collectively, hypermnesia as measured by net recall is possible for items from multiple sets, but at the cost of accurate source information.

Generic noun phrases ("Birds lay eggs") are important for expressing knowledge about abstract kinds. The authors hypothesized that genericity would be part of gist memory, such that young children would appropriately recall whether sentences were presented as generic or specific. In 4 experiments, preschoolers and college students (N = 280) heard a series of sentences in either generic form (e.g., "Bears climb trees") or specific form (e.g., "This bear climbs trees") and were asked to recall the sentences following a 4-min distractor task. Participants in all age groups correctly distinguished between generic and specific noun phrases (NPs) in their recall, even when forgetting the details of the NP form. Memory for predicate content (e.g., "climb trees") was largely unaffected by genericity, although memory for category labels (e.g., "bear") was at times better for those who heard sentences with generic wording. Overall, these results suggest that generic form is maintained in long-term memory even for young children and thus may serve as the foundation for constructing knowledge about kinds.
