Prospective memory

Dong Dong, Lawrence K F Wong, Zhiwei Luo
By using slide-based task in a laboratory setting, previous studies have found that activation of the rostral prefrontal cortex (BA10) is related to prospective memory performance. In this present study, we used immersive virtual reality (VR) technology to measure PM performance in a real-life task in a simulated virtual environment. Functional near-infrared spectroscopy was used simultaneously to record the rostral prefrontal cortex activities of the subjects. By comparing the data against the ones from the slide-based task, the result suggested that the activation of BA10 in the VR tasks were greater than the one in the slide-based tasks, and the VR tasks have the potential to identify the particular location of BA10 that is connected to the PM performance in our daily lives...

Background: physical function (PF) and physical activity (PA) both decline as adults age and have been linked to negative outcomes, including dementia, depression and cardiovascular diseases. Although declines in each are associated with numerous negative outcomes, the longitudinal relationship between these two measures is unclear. Objective: to examine the dynamic, bidirectional associations between declines in PF and PA. Design: prospective cohort...

OBJECTIVE: The current article set out to review all research conducted to date investigating prospective memory (PM) in autism. METHOD: All studies on PM in autism are first described, followed by a critical review and discussion of experimental findings within the multiprocess framework. PM in autism is then considered through an embodied predictive-coding account of autism. RESULTS: Overall, despite somewhat inconsistent methodologies, a general deficit in PM in autism is observed, with evidence mostly in line with the multiprocess framework...

OBJECTIVES: Posttraumatic stress disorder (PTSD) has been consistently associated with episodic memory deficits. To some extent, these deficits could be related to an impairment of metamemory in individuals with PTSD. This research consequently aims at investigating prospective (feeling-of-knowing, FOK) and retrospective (confidence) metamemory judgments for episodic information in PTSD. METHOD: Twenty participants with PTSD and without depression were compared to 30 healthy comparison participants on metamemory judgments during an episodic memory task...

Previous research has indicated that executive function (EF) is negatively associated with aggressive behavior in childhood. However, there is a lack of longitudinal studies that have examined the effect of deficits in EF on aggression over time and taken into account different forms and functions of aggression at the same time. Furthermore, only few studies have analyzed the role of underlying variables that may explain the association between EF and aggression. The present study examined the prospective paths between EF and different forms (physical and relational) and functions (reactive and proactive) of aggression...

Objectives: The increasing number of reports on infections due to carbapenem-resistant Gram-negative bacilli (GNB) has raised concerns, because they have complicated empiric or guided antibiotic therapy for critically ill patients. We aimed to develop a scoring system to predict nosocomial imipenem-resistant GNB (IR-GNB) septicemia among the critically ill patients. Materials and methods: The study included critically ill adult patients with nosocomial GNB septicemia at Kaohsiung Chang Gung Memorial Hospital (CGMH) in 2013-2015, and the scoring system for predicting IR-GNB septicemia was developed, followed by prospective validation conducted among patients at Linkou CGMH and Kaohsiung CGMH between January and June, 2016...

OBJECTIVES: Cardiac arrest etiology may be an important source of between-patient heterogeneity, but the impact of etiology on organ injury is unknown. We tested the hypothesis that asphyxial cardiac arrest results in greater neurologic injury than cardiac etiology cardiac arrest (ventricular fibrillation cardiac arrest), whereas ventricular fibrillation cardiac arrest results in greater cardiovascular dysfunction after return of spontaneous circulation. DESIGN: Prospective observational human and randomized animal study...

Prospective memory is defined as remembering to do something at a particular moment in the future and may be modulated by sleep. Here, we investigated whether multiple nights of partial sleep deprivation would affect the successful retrieval of intentions. Fifty-nine adolescents (mean age ± SD: 16.1 ± 0.6 years) were instructed to remember to press specific keys in response to the target words presented during a semantic categorization task in the future. Their memory was tested after five nights of either 5-h (sleep restriction group) or 9-h time-in-bed (control group)...

PURPOSE: One in three breast cancer survivors experiences persistent cognitive changes that can negatively impact daily functioning and quality of life. In our cancer center, the largest tertiary cancer center in Canada, patients with self-reported cancer-related cognitive dysfunction (CRCD) are offered psychoeducation intended to reduce distress about CRCD symptoms and improve everyday cognitive performance, but evidence regarding this intervention's impact is lacking. Here, we assess whether a 1-hour (h), individual psychoeducational intervention designed to promote self-management of CRCD symptoms can improve attitudes and coping with memory-related difficulties in women with breast cancer...

INTRODUCTION: Patient falls are a significant issue in hospitalized patients and financially costly to hospitals. The Joint Commission requires that patients be assessed for fall risk and interventions in place to mitigate the risk of falls. It is imperative to have a patient population/setting specific fall risk assessment tool to identify patients at risk for falling. The purpose of this study was to evaluate the reliability and validity of the 2013 Memorial ED Fall Risk Assessment tool (MEDFRAT) specifically designed for the ED population...

In this chapter, the neuropsychologic literature concerning memory deficits following parietal lesions is reviewed. Left inferior parietal lobule lesions definitely cause verbal short-term memory impairments, while right parietal lesions disrupt visuospatial short-term memory. Episodic memory, as well as autobiographic memory, does not seem to be impaired after both unilateral and bilateral parietal lesions, in contrast with neuroimaging studies reporting activation of the lateral parietal cortex during memory tasks...

Antibody-mediated rejection is currently the leading cause of transplant failure. Prevailing dogma predicts that B cells differentiate into anti-donor-specific antibody (DSA)-producing plasma cells only with the help of CD4+ T cells. Yet, previous studies have shown that dependence on helper T cells decreases when high amounts of protein antigen are recruited to the spleen, two conditions potentially met by organ transplantation. This could explain why a significant proportion of transplant recipients develop DSA despite therapeutic immunosuppression...
