Sleep Deprivation and Advice Taking

This is the final version. Available on open access from Nature Research via the DOI in this recordJudgements and decisions in many political, economic or medical contexts are often made while sleep deprived. Furthermore, in such contexts individuals are required to integrate information provided by – more or less qualified – advisors. We asked if sleep deprivation affects advice taking. We conducted a 2 (sleep deprivation: yes vs. no) ×2 (competency of advisor: medium vs. high) experimental study to examine the effects of sleep deprivation on advice taking in an estimation task. We compared participants with one night of total sleep deprivation to participants with a night of regular sleep. Competency of advisor was manipulated within subjects. We found that sleep deprived participants show increased advice taking. An interaction of condition and competency of advisor and further post-hoc analyses revealed that this effect was more pronounced for the medium competency advisor compared to the high competency advisor. Furthermore, sleep deprived participants benefited more from an advisor of high competency in terms of stronger improvement in judgmental accuracy than well-rested participants.Volkswagen Foundatio

National Assessment of the Potential Consequences of Climate Variability and Change for the United States

The first U.S. National Assessment of the PotentialConsequences of Climate Variability and Change for theUnited States is being conducted under the auspices of theU.S. Global Change Research Program (USGCRP). TheUSGCRP was established through the Global ChangeResearch Act of 1990 (P.L. 101-606) and mandatedthrough the statute with the responsibility to undertakeperiodic scientific assessments of the potentialconsequences of global change for the United States. Thegoal of the National Assessment is to analyze andevaluate what is known about the potential consequencesof climate variability and change for the nation in thecontext of other pressures on the public, the environment,and the nation\u27s resources. The conduct of the nationalassessment process will involve a broad spectrum ofstakeholders from state, local, tribal, and Federalgovernments; business; labor; academia; non-profitorganizations; and the general public. The assessmentwill link research by scientists to specific needs of thestakeholders, and will provide planners, managers,organizations, and the public with the information neededto increase resilience to climate variability and cope withclimate change. The national assessment will becomprised of three components: (1) National synthesis,(2) Sectoral analyses (agriculture, forestry, waterresources, human health, and the coastal zone), and(3) Regional analyses. To facilitate comparison,integration, and synthesis of each of the assessmentcomponents, all regional, sectoral, and synthesis analyseswill use a common set of scenarios for climate change and changes in socio-economic conditions. Specific responsibilities have been defined for oversight of the components of the national assessment and forcoordination activities. A National Assessment SynthesisTeam (NAST) will provide overall intellectual oversightof the national assessment process and has responsibilityfor the development of the Synthesis Report. A NationalAssessment Working Group under the auspices of theUSGCRP has lead responsibility for organizing andsponsoring the sectoral analyses and oversight andcoordination responsibilities for regional analyses. ANational Assessment Coordination Office has beenestablished to facilitate coordination of the entire nationalassessment process. The National Assessment SynthesisReport is targeted for completion by January 1, 2000, andis intended to satisfy the mandate for an assessmentdefined in P.L. 101-606 and serve as part of the U.S.contribution to the IPCC Third Assessment Report

Child-resistant and tamper-resistant packaging: A systematic review to inform tobacco packaging regulation

We aimed to investigate the effects of special packaging (child-resistant, adult-friendly) and tamper-resistant packaging on health and behavioral outcomes in order to identify research gaps and implications for packaging standards for tobacco products

Learning Languages and Complex Subjects with Memory Palaces

A memory palace is an ancient technique of using space as a way of organizing memories. It’s a powerful tool for learning, retaining, and recalling large amounts of complex information quickly and effectively. In the middle ages, these techniques were widely used to learn and compose large texts and works of literature. In this paper, we present the fundamental theory behind memory palaces as the foundation for the project Macunx - a VR platform for building memory palaces to learn huge amounts in short time and with full retention - as well as the initial stages of its development. The paper concludes with a discussion of the future stages over the testing of the package with end-users for its final refinement

Applications of functional near-infrared spectroscopy (fNIRS) in studying cognitive development: the case of mathematics and language

We discuss how technical limitations of common neuroimaging techniques such as functional magnetic resonance imaging (fMRI) have resulted in our limited understanding of neural changes during development, while fNIRS would be a suitable and child-friendly method to examine cognitive development. We suggest fNIRS as an additional technique to track brain activation changes in the field of educational neuroscienc

The role of rapid eye movement sleep for amygdala-related memory processing

Contains fulltext : 154252.pdf (Publisher’s version ) (Open Access)Over the years, rapid eye movement (REM) sleep has been associated with general memory consolidation, specific consolidation of perceptual, procedural, emotional and fear memories, brain maturation and preparation of waking consciousness. More recently, some of these associations (e.g., general and procedural memory consolidation) have been shown to be unlikely, while others (e.g., brain maturation and consciousness) remain inconclusive. In this review, we argue that both behavioral and neurophysiological evidence supports a role of REM sleep for amygdala-related memory processing: the amygdala-hippocampus-medial prefrontal cortex network involved in emotional processing, fear memory and valence consolidation shows strongest activity during REM sleep, in contrast to the hippocampus-medial prefrontal cortex only network which is more active during non-REM sleep. However, more research is needed to fully understand the mechanisms.12 p
