Distinguishing explicit from implicit knowledge on the basis of the active representation of certain propositional attitudes fails to provide an explanation for dissociations in learning performance under implicit and explicit conditions. This suggests an account of implicit and explicit knowledge grounded in the presence of multiple learning mechanisms, and multiple brain systems more generally. A rough outline of a connectionist account of this kind is provided.

The dynamical hypothesis is strong in that, for it to be true, every cognitive phenomenon must be best modeled by a dynamical system. Depending on how it is interpreted, however, the hypothesis may be seen as probably false or even unfalsifiable. Strengthening the hypothesis to require unification, or at least coherence, across models in different cognitive domains alleviates this problem.

Rich sensorimotor interaction facilitates language learning and is presumed to ground conceptual representations. Yet empirical support for early stages of embodied word learning is currently lacking. Finding evidence that sensorimotor interaction shapes learned linguistic representations would provide crucial support for embodied language theories. We developed a gamified word learning experiment in virtual reality in which participants learned the names of six novel objects by grasping and manipulating objects with either their left or right hand. Participants then completed a word–color match (...) task in which they were tested on the same six words and objects. Participants were faster to respond to stimuli in the match task when the response hand was compatible with the hand used to interact with the named object, an effect we refer to as affordance compatibility. In two follow up experiments, we found that merely observing virtual hands interact with the objects was sufficient to acquire a smaller affordance compatibility effect, and we found that the compatibility effect was driven primarily by responses with a compatible hand and not by responses in a compatible spatial location. Our results support theoretical views of language which ground word representations in sensorimotor experiences, and they suggest promising future routes to explore the sensorimotor foundations of higher cognition through immersive virtual experiments.

In recent years, Bayesian probability theory has emerged not only as a powerful tool for building computational theories of vision, but also as a general paradigm for studying human visual perception. This book provides an introduction to and critical analysis of the Bayesian paradigm. Leading researchers in computer vision and experimental vision science describe general theoretical frameworks for modeling vision, detailed applications to specific problems and implications for experimental studies of human perception. The book provides a dialogue between different perspectives (...) both within chapters, which draw on insights from experimental and computational work, and between chapters, through commentaries written by the contributors on each other's work. Students and researchers in cognitive and visual science will find much to interest them in this thought-provoking collection. (shrink)

The organism is one of the fundamental concepts of biology and has been at the center of many discussions about biological individuality, yet what exactly it is can be confusing. The definition that we find generally useful is that an organism is a unit in which all the subunits have evolved to be highly cooperative, with very little conflict. We focus on how often organisms evolve from two or more formerly independent organisms. Two canonical transitions of this type—replicators clustered in (...) cells and endosymbiotic organelles within host cells—demonstrate the reality of this kind of evolutionary transition and suggest conditions that can favor it. These conditions include co-transmission of the partners across generations and rules that strongly regulate and limit conflict, such as a fair meiosis. Recently, much attention has been given to associations of animals with microbes involved in their nutrition. These range from tight endosymbiotic associations like those between aphids and Buchnera bacteria, to the complex communities in animal intestines. Here, starting with a reflection about identity through time, we consider the distinctions between these kinds of animal–bacteria interactions and describe the criteria by which a few can be considered jointly organismal but most cannot.

We investigate introduction and elimination rules for truth-functional connectives, focusing on the general questions of the existence, for a given connective, of at least one such rule that it satisfies, and the uniqueness of a connective with respect to the set of all of them. The answers are straightforward in the context of rules using general set/set sequents of formulae, but rather complex and asymmetric in the restricted (but more often used) context of set/formula sequents, as also in the intermediate (...) set/formula-or-empty context.

Leading a corporation through a crisis requires rational decision making guided by an ethical approach (Snyder et al., Journal of Business Ethics, 63, 2006, 371). Three such approaches are virtue ethics (Seeger and Ulmer, Journal of Business Ethics, 31, 2001, 369), an ethic of justice, and an ethic of care (Simóla, Journal of Business Ethics, 46, 2003, 351). In this article, I consider the effectiveness of these approaches for leading a corporation after a crisis. The standard I use is drawn (...) from recent studies that examine how people tend to react to corporate unintentional harms. I conclude from these studies that an ethic of care approach is most effective for managing corporate crises when it comes to stakeholder concerns. I conclude the article with strategies for managing a crisis using an ethic of care. (shrink)

"Dr. Rubin has brought cognitive psychology into a wholly unprecedented dialogue with studies in oral tradition. The result is a truly new perspective on memory and the processes of oral tradition." --John Miles Foley, University of Missouri.

Amor Dei, “love of God” raises three questions: How do we know God is love? How do we experience love of God? How free are we to love God? This book presents three kinds of love, worldly, spiritual, and divine to understand God’s love. The work begins with Augustine’s Confessions highlighting his Manichean and Neoplatonic periods before his conversion to Christianity. Augustine’s confrontation with Pelagius anticipates the unresolved disputes concerning God’s love and free will. In the sixteenth-century the Italian humanist, (...) Gasparo Contarini introduces the notion of “divine amplitude” to demonstrate how God’s goodness is manifested in the human agent. Pierre de Bérulle, Guillaume Gibieuf, and Nicolas Malebranche show connections with Contarini in the seventeenth-century controversies relating free will and divine love. In response to the free will dispute, the Scottish philosopher, William Chalmers, offers his solution. Cornelius Jansen relentlessly asserts his anti-Pelagian interpretation of Augustine stirring up more controversy. John Norris, Malebranche’s English disciple, exchanges his views with Mary Astell and Damaris Masham. In the tradition of Cambridge Platonism, Ralph Cudworth conveys a God who “sweetly governs.” The organization of sections represents the love of God in ascending-descending movements demonstrating that, “human love is inseparable from divine love.”.

The existing literature in medical ethics does not serve the practical needs of medical students and trainees very well. Medical students or junior doctors often have their own set of ethical concerns and the dilemmas that arise are generally beyond their direct control. The editors have addressed the gap in the literature by compiling a series of case studies from around the world and inviting an international team of leading ethicists and clinicians to comment on them. This volume includes over (...) 80 actual cases that cover the range of possible problems a medical trainee may encounter on the ward. (shrink)

In this article 1 I have two theological interests and a less direct philosophical one.

In a morally fragmented society there is no good reason for ethics committees to assume any particular point of view, yet failure to do so compromises their ability to function in either a case‐review or an educational capacity. A casuist methodology might enable committees to fulfill both roles.

Kin selection is a core aspect of social evolution theory, but a small number of critics have recently challenged it. Here I address these criticisms and show that kin selection remains an important explanation for much social evolution. I show how many of the criticisms rest on historical idiosyncrasies of the way the field happened to develop, rather than on the real logic and evidence.

Biologists and philosophers differ on whether selection should be analyzed at the level of the gene or of the individual. In Peter Godfrey-Smith’s book, Darwinian Populations and Natural Selection, he argues that individuals can be good members of Darwinian populations, whereas genes rarely can. I take issue with parts of this view, and suggest that Godfrey-Smith’s scheme for thinking about Darwinian populations is also applicable to populations of genes.

Past ages of medical care are condemned in modern philosophical and medical literature as being too paternalistic. The normal account of good medicine in the past was, indeed, paternalistic in an offensive way to modern persons. Imagine a Jean Paul Sartre going to the doctor and being treated without his consent or even his knowledge of what will transpire during treatment! From Hippocratic times until shortly after World War II, medicine operated in a closed, clubby manner. The knowledge learned in (...) medicine was not shared with the patients, who were in general poorly educated and for the most part completely ignorant of the craft of medicine and the physicians. Physicians were cautioned against telling patients too much about their Illness and/or their recovery, perhaps because physicians themselves did not have an enormous armamentarium to confront disease.

William James is frequently considered one of America's most important philosophers, as well as a foundational thinker for the study of religion. Despite his reputation as the founder of pragmatism, he is rarely considered a serious philosopher or religious thinker. In this new interpretation David Lamberth argues that James's major contribution was to develop a systematic metaphysics of experience integrally related to his developing pluralistic and social religious ideas. Lamberth systematically interprets James's radically empiricist world-view and argues for an (...) early dating for his commitment to the metaphysics of radical empiricism. He offers a close reading of Varieties of Religious Experience; and concludes by connecting James's ideas about experience, pluralism and truth to current debates in philosophy, the philosophy of religion, and theology, suggesting James's functional, experiential metaphysics as a conceptual aid in bridging the social and interpretive with the immediate and concrete while avoiding naive realism.

Our global knowledge of different cultures and the diversity of values increases almost daily. New challenges arise for ethics. This is especially true in the field of bioethics because the technological progress of medicine throughout the world is causing dramatic interactions with traditionally held values. Science and technology are rapidly advancing beyond discussions and corresponding political struggles over human rights, leaving those debates behind. This rapid development of science is at odds with the principle of sustained development that calls for (...) measured and thoughtful planning, such that no new idea should rupture the delicate fabric of communities, environment, and cultural evolution.

While environmental claims are increasingly used by companies to appeal consumers, they also attract greater scrutiny from independent parties interested in consumer protection. Consumers are now able to compare corporate environmental claims against external, often disconfirming, information to form their brand attitudes and purchase intentions. What remains unclear is how the level of information specificity of both the environmental claims and external disconfirming information interact to influence consumer reactions. Two experiments address this gap in the CSR communication literature. When specific (...) claims are countered by specific external information, consumers report more negative brand attitudes and lower purchase intentions. The effect is serially mediated by skepticism toward the claims and lack of corporate credibility. We conclude by discussing strategies that firms can utilize to avoid information dilution and ensure that external disconfirming information percolates to consumers as specific. (shrink)

We explore ways in which purely qualitative belief change in the AGM tradition throws light on options in the treatment of conditional probability. First, by helping see why it can be useful to go beyond the ratio rule defining conditional from one-place probability. Second, by clarifying what is at stake in different ways of doing that. Third, by suggesting novel forms of conditional probability corresponding to familiar variants of qualitative belief change, and conversely. Likewise, we explain how recent work on (...) the qualitative part of probabilistic inference leads to a very broad class of 'proto-probability' functions. (shrink)

Propositions about the nature of expertise, in general, and expertise in pedagogy, in particular, are discussed. The time needed to develop expertise in teaching and the highly contextual nature of teachers’ knowledge are also discussed. Four theories of teacher development are presented, with an elaboration on the heuristic value of the theory of Dreyfus and Dreyfus (1986). Examples from the pedagogical literature are used to illustrate this theory. The recent research establishing causal relationships between those identified as experts in teaching (...) and their students’ academic achievement is also presented. This research allows those who study expertise in teaching to have a more objective measure for identifying and studying expert pedagogues. (shrink)

Populations around the world are aging at a very fast rate, so much so that care for the elderly will soon rupture even the most carefully planned, enlightened care provisions societies can offer. The demographics in advanced countries demonstrate this dilemma, even without projections based on antiaging medications that may be possible in the near future, and a healthier lifestyle that has preoccupied the yuppies for about 10 years.

The target article skillfully evaluates data on mental disorders in relation to predictions from evolutionary genetic theories of neutral evolution, balancing selection, and polygenic mutation-selection balance, resulting in a negative outlook for the likelihood of success finding genes for mental disorders. Nevertheless, new conceptualizations, methods, and continued interactions across disciplines provide hope.

We comment that covariances between brain divisions may be constraining or facilitating, depending on what is being selected, and that modern quantitative genetic methods provide the tools to discover and manipulate the genetic networks that give rise to the covariances described in the target article.

In this essay I will examine why the truth is so important to human communication in general, the types of truth, and why truth is only a relative value. After those introductory points, I will sketch the ways in which the truth is overridden or trumped by other concerns in the clinical setting. I will then discuss cases that fall into five distinct categories. The conclusion emphasizes the importance of truth telling and its primacy among secondary goods in the healthcare (...) professional-patient relationship. (shrink)
