Why does performing certain tasks cause the aversive experience of mental effort and concomitant deterioration in task performance? One explanation posits a physical resource that is depleted over time. We propose an alternative explanation that centers on mental representations of the costs and benefits associated with task performance. Specifically, certain computational mechanisms, especially those associated with executive function, can be deployed for only a limited number of simultaneous tasks at any given moment. Consequently, the deployment of these computational mechanisms carries (...) an opportunity cost – that is, the next-best use to which these systems might be put. We argue that the phenomenology of effort can be understood as the felt output of these cost/benefit computations. In turn, the subjective experience of effort motivates reduced deployment of these computational mechanisms in the service of the present task. These opportunity cost representations, then, together with other cost/benefit calculations, determine effort expended and, everything else equal, result in performance reductions. In making our case for this position, we review alternative explanations for both the phenomenology of effort associated with these tasks and for performance reductions over time. Likewise, we review the broad range of relevant empirical results from across sub-disciplines, especially psychology and neuroscience. We hope that our proposal will help to build links among the diverse fields that have been addressing similar questions from different perspectives, and we emphasize ways in which alternative models might be empirically distinguished.

There is growing interest in contact tracing apps for pandemic management. It is crucial to consider ethical requirements before, while, and after implementing such apps. In this paper, we illustrate the complexity and multiplicity of the ethical considerations by presenting an ethical framework for a responsible design and implementation of CT apps. Using this framework as a starting point, we briefly highlight the interconnection of social and political contexts, available measures of pandemic management, and a multi-layer assessment of CT apps. (...) We will discuss some trade-offs that arise from this perspective. We then suggest that public trust is of major importance for population uptake of contact tracing apps. Hasty, ill-prepared or badly communicated implementations of CT apps will likely undermine public trust, and as such, risk impeding general effectiveness. (shrink)

Making data broadly accessible is essential to creating a medical information commons. Transparency about data-sharing practices can cultivate trust among prospective and existing MIC participants. We present an analysis of 34 initiatives sharing DNA-derived data based on public information. We describe data-sharing practices captured, including practices related to consent, privacy and security, data access, oversight, and participant engagement. Our results reveal that data-sharing initiatives have some distance to go in achieving transparency.

Advances in technologies and biomedical informatics have expanded capacity to generate and share biomedical data. With a lens on genomic data, we present a typology characterizing the data-sharing landscape in biomedical research to advance understanding of the key stakeholders and existing data-sharing practices. The typology highlights the diversity of data-sharing efforts and facilitators and reveals how novel data-sharing efforts are challenging existing norms regarding the role of individuals whom the data describe.

Der Kinder- und Jugendgesundheitssurvey soll repräsentative, gültige Daten und Erkenntnisse zur gesundheitlichen Situation von Kindern und Jugendlichen in Deutschland als entscheidende Voraussetzung für die Bewertung und die Verbesserung von deren gesundheitlicher Lage schaffen. Forschung und insbesondere Blutentnahmen an nichteinwilligungsfähigen Personen erfordern eine profunde ethische und rechtliche Überprüfung. Der Beitrag befasst sich damit, welche medizinethischen Empfehlungen und welche rechtlichen Grundsätze in Deutschland für die Bewertung relevant sind. Nach geltendem deutschen Recht können Eltern zu Blutentnahmen bei ihren Kindern nur zustimmen, wenn diese (...) in deren individuellem gesundheitlichen Interesse liegen. Ein „gruppenspezifischer Nutzen“, wie er von Medizinethikern national und international als Voraussetzung für ethische Akzeptabilität (bei minimalem Risiko der Untersuchungen) ebenfalls für sinnvoll und wichtig angesehen wird, und der in dem geplanten Survey in jedem Falle gegeben wäre, genügt deutschen Rechtsansprüchen nicht. Im Pretest hat sich der potenzielle individuelle Nutzen der Blutentnahmen bestätigt: Viele Kinder hatten biochemisch nachweisbare Gesundheitsrisiken (z. B. verborgener Nährstoffmangel, allergische Sensibilisierung, Hinweise auf Impflücken oder langfristige Gesundheitsrisiken), die ohne Blutuntersuchung nicht feststellbar gewesen wären. Bei über 90% der Kinder waren nach schriftlicher Einwilligung der Eltern und Jugendlichen sowie informeller Zustimmung der Kinder, die in jedem einzelnen Falle berücksichtigt wurde, Blutentnahmen möglich. Nach der Befragung einer Unterstichprobe ist die Akzeptanz insgesamt gut. (shrink)

A 2011 National Academies of Sciences report called for an “Information Commons” and a “Knowledge Network” to revolutionize biomedical research and clinical care. We interviewed 41 expert stakeholders to examine governance, access, data collection, and privacy in the context of a medical information commons. Stakeholders' attitudes about MICs align with the NAS vision of an Information Commons; however, differences of opinion regarding clinical use and access warrant further research to explore policy and technological solutions.

A medical information commons is a networked data environment utilized for research and clinical applications. At three deliberations across the U.S., we engaged 75 adults in two-day facilitated discussions on the ethical and social issues inherent to sharing data with an MIC. Deliberants made recommendations regarding opt-in consent, transparent data policies, public representation on MIC governing boards, and strict data security and privacy protection. Community engagement is critical to earning the public's trust.

Drawing on a landscape analysis of existing data-sharing initiatives, in-depth interviews with expert stakeholders, and public deliberations with community advisory panels across the U.S., we describe features of the evolving medical information commons. We identify participant-centricity and trustworthiness as the most important features of an MIC and discuss the implications for those seeking to create a sustainable, useful, and widely available collection of linked resources for research and other purposes.

In this paper, the results of a pilot interview study with 19 subjects participating in an EEG-based non-invasive brain–computer interface (BCI) research study on stroke rehabilitation and assistive technology and of a survey among 17 BCI professionals are presented and discussed in the light of ethical, legal, and social issues in research with human subjects. Most of the users were content with study participation and felt well informed. Negative aspects reported include the long and cumbersome preparation procedure, discomfort with the (...) cap and the wet electrodes, problems concerning BCI control, and strains during the training sessions. In addition, some users reflected on issues concerning system security. When asked for morally problematic issues in this field of non-invasive BCI research, the BCI professionals stressed the need for correct information transfer, the obligation to avoid unrealistic expectations in study participants, the selection of study participants, benefits and strains of participation, BCI illiteracy, the possibility of detrimental brain modifications induced by BCI use, and problems that may arise at the end of the trials. Furthermore, privacy issues were raised. Based on the results obtained, psychosocial and ethical aspects of EEG-based non-invasive BCI research are discussed and possible implications for future research addressed. (shrink)

In this paper I take Hempel’s raven paradox as the claim that statements of the form ‘∼Ru v Bu’, ‘u is not a raven or u is black,’ confirm the hypothesis h ‘(x)(Rx → Bx)’, ‘All ravens are black.’ Although Hempel discusses this using a criterion of confirmation expressed wholly in terms of deductive logic (see 1965, pp. 35-9), it has become more common to articulate criteria of confirmation using concepts of probability and, in particular, to employ the (...) positive relevance criterion of confirmation which says that, given background knowledge k, (i) e confirms h if and only if P(h/e.k)>P(h/k); (ii) e disconfirms h if and only if P(h/e.k)shrink)

A uniquely playful and incisive illustrated collection of Zen teaching stories from one of America's best-known and most-respected Zen masters. A Modern Classic. In the tradition of the great koan collections and the extensive records of ancient masters, Robert Aitken--one of America's best-known and most-respected Zen masters--distills a lifetime of teaching down to its essence. Intriguing, playful, and deceptively easy to read, Zen Master Raven is a brilliant encapsulation of Zen in over a hundred koan-like encounters--featuring curious beginners like (...) Mallard and Mole, to teachers-in-training like Porcupine, to the profound wisdom of masters like Brown Bear, Moose Roshi, and Zen Master Raven himself. (shrink)

ABSTRACTThe financial crisis of 2008 was unforeseen partly because the academic theories that underpin policy making do not sufficiently account for uncertainty and complexity or learned and evolved human capabilities for managing them. Mainstream theories of decision making tend to be strongly normative and based on wishfully unrealistic “idealized” modeling. In order to develop theories of actual decision making under uncertainty, we need new methodologies that account for how human actors often manage uncertain situations “well enough.” Some possibly helpful methodologies, (...) drawing on digital science, focus on the role of emotions in determining people's choices; others examine how people construct narratives that enable them to act; still others combine qualitative with quantitative data.

Regular musical activity as a complex multimodal lifestyle activity is proposed to be protective against age-related cognitive decline and Alzheimer’s disease. This cross-sectional study investigated the association and interplay between musical instrument playing during life, multi-domain cognitive abilities and brain morphology in older adults from the DZNE-Longitudinal Cognitive Impairment and Dementia Study study. Participants reporting having played a musical instrument across three life periods were compared to controls without a history of musical instrument playing, well-matched for reserve proxies of education, (...) intelligence, socioeconomic status and physical activity. Participants with musical activity outperformed controls in global cognition, working memory, executive functions, language, and visuospatial abilities, with no effects seen for learning and memory. The musically active group had greater gray matter volume in the somatosensory area, but did not differ from controls in higher-order frontal, temporal, or hippocampal volumes. However, the association between gray matter volume in distributed frontal-to-temporal regions and cognitive abilities was enhanced in participants with musical activity compared to controls. We show that playing a musical instrument during life relates to better late-life cognitive abilities and greater brain capacities in OA. Musical activity may serve as a multimodal enrichment strategy that could help preserve cognitive and brain health in late life. Longitudinal and interventional studies are needed to support this notion. (shrink)

We present a one per cent measurement of the cosmic distance scale from the detections of the baryon acoustic oscillations in the clustering of galaxies from the Baryon Oscillation Spectroscopic Survey, which is part of the Sloan Digital Sky Survey III. Our results come from the Data Release 11 sample, containing nearly one million galaxies and covering approximately 8500 square degrees and the redshift range 0.2 < z < 0.7. We also compare these results with those from the publicly released (...) DR9 and DR10 samples. Assuming a concordance Λ cold dark matter cosmological model, the DR11 sample covers a volume of 13 Gpc3 and is the largest region of the Universe ever surveyed at this density. We measure the correlation function and power spectrum, including density-field reconstruction of the BAO feature. The acoustic features are detected at a significance of over 7σ in both the correlation function and power spectrum. Fitting for the position of the acoustic features measures the distance relative to the sound horizon at the drag epoch, rd, which has a value of rd,fid = 149.28 Mpc in our fiducial cosmology. We find DV = at z = 0.32 and DV = at z = 0.57. At 1.0 per cent, this latter measure is the most precise distance constraint ever obtained from a galaxy survey. Separating the clustering along and transverse to the line of sight yields measurements at z = 0.57 of DA = and H =. Our measurements of the distance scale are in good agreement with previous BAO measurements and with the predictions from cosmic microwave background data for a spatially flat CDM model with a cosmological constant. © 2014 The Author Published by Oxford University Press on behalf of the Royal Astronomical Society.

This article is about David Hume's account of mixed emotions. Hume on mixed emotions is connected with Sir Isaac Newton's optical experiments and subsequent invention of the colour wheel, as well as more recently to Robert Plutchik's colour wheel of emotions.

What is the opposite of freedom? In _Freedom as Marronage_, Neil Roberts answers this question with definitive force: slavery, and from there he unveils powerful new insights on the human condition as it has been understood between these poles. Crucial to his investigation is the concept of marronage—a form of slave escape that was an important aspect of Caribbean and Latin American slave systems. Examining this overlooked phenomenon—one of action from slavery and toward freedom—he deepens our understanding of freedom (...) itself and the origin of our political ideals. Roberts examines the liminal and transitional space of slave escape in order to develop a theory of freedom as marronage, which contends that freedom is fundamentally located within this space—that it is a form of perpetual flight. He engages a stunning variety of writers, including Hannah Arendt, W. E. B. Du Bois, Angela Davis, Frederick Douglass, Samuel Taylor Coleridge, and the Rastafari, among others, to develop a compelling lens through which to interpret the quandaries of slavery, freedom, and politics that still confront us today. The result is a sophisticated, interdisciplinary work that unsettles the ways we think about freedom by always casting it in the light of its critical opposite. (shrink)

Simon Blackburn’s How to Read Hume, Robert Fogelin’s Hume’s Skeptical Crisis: A Textual Study and John P. Wright’s Hume’s ‘A Treatise of Human Nature’: An Introduction are all clear and highly readable works directed at audiences of students and other non-specialists. Given that all three of the authors are prominent and distinguished Hume scholars, I suspect these works will be of great interest to Hume specialists as well. This piece first summarizes the aims and methods of each book and next, (...) by way of evaluation, compares and contrasts each author’s work on four features that contribute to the general character of an introductory work devoted to Hume’s philosophy.

An important debate in the reasoning literature concerns the extent to which inference processes are domain-free or domain-specific. Typically, evidence in support of the domain-specific position comprises the facilitation observed when abstract reasoning tasks are set in realistic context. Three experiments are reported here in which the sources of facilitation were investigated for contextualised versions of Raven's Progressive Matrices (Richardson, 1991) and non-verbal analogies from the AH4 test (Richardson & Webster, 1996). Experiment 1 confirmed that the facilitation observed for (...) the contextualised matrices was in part due to extraneous aspects of commentaries originally intended to activate domainspecific processes. Experiments 2 and 3 indicated that the remainder of the facilitation for the matrices, and all of the facilitation for the analogies, could be explained by visual salience: Converting the item elements into realistic objects had enabled them and their transitions to be identified more easily. Hence, performance at simplified abstract items was as good as, or better than, at contextualised items. It is concluded that facilitation effects cannot be interpreted as showing that domain-specific processes constitute a self-contained system separate from domain-free processes. In turn, this means that domain-free processes cannot be dismissed as being unimportant for reasoning. (shrink)

Der vorliegende Band umfasst Beitrage zu einem zentralen Thema bei Platon: 'Physis' kann bei Platon im naturwissenschaftlichen Sinne als physische, biologische, materielle Natur oder im ubertragenen Sinne als eigenes Wesen, etwa hinsichtlich Seele, Kosmos oder Gottlichem, verstanden werden. So werden in diesem Band medizinische, biologische und kosmologische Ansatze ebenso wie ontologische, epistemologische und padagogische Themen zu Platons 'Physis'-Konzept fokussiert. Die zeitgenossische Nomos-Physis-Diskussion Platons mit den Sophisten sowie seine sprach- und kulturphilosophischen Uberlegungen spielen hier eine wichtige Rolle. Die anspruchsvolle literarische Gestaltung (...) der Platonischen Dialoge ist fur die genannten Fragestellungen hochst relevant, ebenso die Auseinandersetzung spaterer platonischer Philosophen mit Platons Physis-Konzept.

This comment responds to Maul’s (2012) article evaluating the validity evidence and argument for the Mayer–Salovey–Caruso Emotional Intelligence Test (MSCEIT) as a measure of emotional intelligence (EI). We suggest that Maul’s standards for establishing validity evidence are unrealistically high, and may not be met by other established psychometric tests. As an example, we show that evidence for the validity of Raven’s Progressive Matrices (RPM) is of a similar standard to the MSCEIT.

Out of the ferment of recent debates about the intellectual virtues, Roberts and Wood have developed an approach they call 'regulative epistemology'. This is partly a return to classical and medieval traditions, partly in the spirit of Locke's and Descartes's concern for intellectual formation, partly an exploration of connections between epistemology and ethics, and partly an approach that has never been tried before. Standing on the shoulders of recent epistemologists - including William Alston, Alvin Plantinga, Ernest Sosa, and Linda (...) Zagzebski - Roberts and Wood pursue epistemological questions by looking closely and deeply at particular traits of intellectual character such as love of knowledge, intellectual autonomy, intellectual generosity, and intellectual humility. Central to their vision is an account of intellectual goods that includes not just knowledge as properly grounded belief, but understanding and personal acquaintance, acquired and shared through the many social practices of actual intellectual life. This approach to intellectual virtue infuses the discipline of epistemology with new life, and makes it interesting to people outside the circle of professional epistemologists. It is epistemology for the whole intellectual community, as Roberts and Wood carefully sketch the ways in which virtues that would have been categorized earlier as moral make for agents who can better acquire, refine, and communicate important kinds of knowledge.

The aim of this paper is to explain why Thrasymachus, upon first appearing in Republic I, prohibits Socrates from defining justice as what is good. I argue that Thrasymachus views such definitions as equivocal, since he conceives of the good as relative: what is good must be good for someone. This relative conception of the good makes Thrasymachus similar to the sight-lovers, who believe in good things, which are relatively good, but deny the existence of the good itself, which is (...) absolutely good. Understanding Thrasymachus as a sight-lover permits an illuminating reframing of his outlook and his significance for the larger project of the Republic. (shrink)

Jacob Neumann provides a thoughtful reading of Paulo Freire in the 21st century: Education, dialogue, and transformation. His comments on the importance of contextualising Freire’s work and the value of openness in engaging Freirean ideas are insightful and helpful. His use of the term ‘apolitical’ is, however, rather more problematic. Drawing on points made in Paulo Freire in the 21st century, and with links to Freire’s wider philosophy and pedagogy, this article argues that education from a Freirean perspective is always (...) political.

Since the publication of Edmund Gettier's challenge to the traditional epistemological doctrine of knowledge as justified true belief, Roberts and Wood claim that epistemologists lapsed into despondency and are currently open to novel approaches. One such approach is virtue epistemology, which can be divided into virtues as proper functions or epistemic character traits. The authors propose a notion of regulative epistemology, as opposed to a strict analytic epistemology, based on intellectual virtues that function not as rules or even as (...) skills but as habits of the heart. To that end, they divide the task of clarifying and expounding their notion in the book's two parts.In the first part, Roberts and Wood examine various components that constitute their notion of regulative epistemology. The first are the epistemic goods or goals that drive the epistemic process. What is needed, claim Roberts and Wood, is an enriched notion of these goods rather than the restricted notion of justified true belief. Epistemic agents are more than calculating devices in that ….

From the ferment of recent debates about the intellectual virtues, Roberts and Wood develop an approach they call 'regulative epistemology', exploring the connection between knowledge and intellectual virtue. In the course of their argument they analyse particular virtues of intellectual life - such as courage, generosity, and humility - in detail.
