The often esoteric nature of dialogues about "consciousness" which take place in academic circles stands far removed from treatments of the same topic in lower division college classrooms. There, any detailed discussion of the various definitions which have been advanced for this term is likely to lead to frustration on the part of students who have not yet attained the requisite knowledge for appreciating this divergence of opinions. When teaching classes to introductory students, instructors can provide opportunities for students to (...) appreciate the diversity of their own experiences in addition to using more traditional pedagogic methods. In this paper, the author will describe several of the techniques which he has found useful in opening students up to the various panoramas within their minds. (shrink)

Really statistical explanation is a hitherto neglected form of noncausal scientific explanation. Explanations in population biology that appeal to drift are RS explanations. An RS explanation supplies a kind of understanding that a causal explanation of the same result cannot supply. Roughly speaking, an RS explanation shows the result to be mere statistical fallout.

Common sense and philosophical tradition agree that mind makes a difference. What we do depends not only on how our bodies are put together, but also on what we think. Explaining how mind can make a difference has proved challenging, however. Some have urged that the project faces an insurmountable dilemma: either we concede that mentalistic explanations of behavior have only a pragmatic standing or we abandon our conception of the physical domain as causally autonomous. Although each option has its (...) advocates, most theorists have sought a middle way that accommodates both the common-sense view of mind and the metaphysical conviction about the physical world. This volume presents a collection of new, specially written essays by a diverse group of philosophers, each of whom is widely known for defending a particular conception of minds and their place in nature. Contributors include Robert Audi, Lynne Rudder Baker, Tyler Burge, Donald Davidson, Fred Dretske, Ted Honderich, Jennifer Hornsby, Frank Jackson, Jaegwon Kim, Brian P. McLaughlin, Ruth Garrett Millikan, H. W. Noonan, Philip Pettit, Ernest Sosa, and Robert Van Gulick. (shrink)

We report the identification of a recurrent, 520-kb 16p12.1 microdeletion associated with childhood developmental delay. The microdeletion was detected in 20 of 11,873 cases compared with 2 of 8,540 controls and replicated in a second series of 22 of 9,254 cases compared with 6 of 6,299 controls. Most deletions were inherited, with carrier parents likely to manifest neuropsychiatric phenotypes compared to non-carrier parents. Probands were more likely to carry an additional large copy-number variant when compared to matched controls. The clinical (...) features of individuals with two mutations were distinct from and/or more severe than those of individuals carrying only the co-occurring mutation. Our data support a two-hit model in which the 16p12.1 microdeletion both predisposes to neuropsychiatric phenotypes as a single event and exacerbates neurodevelopmental phenotypes in association with other large deletions or duplications. Analysis of other microdeletions with variable expressivity indicates that this two-hit model might be more generally applicable to neuropsychiatric disease. © 2010 Nature America, Inc.

Reform of the federal income tax system has become a perennial item on the domestic policy agenda of the United States, although there is considerable uncertainty over specifics. Indeed the recent report of the President's Advisory Panel on Federal Tax Reform recommended not one but two divergent policy directions. In Fundamental Tax Reform, top experts in tax policy discuss a wide range of issues raised by the prospect of significant tax reform, identifying the most critical questions and considering whether the (...) answers are known, unknown--or unknowable. The debates over tax reform usually concern the advantages and disadvantages of income-based taxation as opposed to any of the several alternative forms of consumption-based taxation. The book opens with chapters that discuss the strengths, weaknesses, and political feasibility of these options. Other chapters consider the effect of tax reform on businesses, especially their investment behavior, and include a discussion of possible problems in any transition to a consumption-based tax; international taxation issues arising in an era of globalization; and individual behavioral response to tax reform, including a view of the topic from the perspective of the relatively new field of behavioral economics.

The American Medical Association enacted its Code of Ethics in 1847, the first such national codification. In this volume, a distinguished group of experts from the fields of medicine, bioethics, and history of medicine reflect on the development of medical ethics in the United States, using historical analyses as a springboard for discussions of the problems of the present, including what the editors call "a sense of moral crisis precipitated by the shift from a system of fee-for-service medicine to a (...) system of fee-for-system medicine, better known as 'managed care.'" The authors begin with a look at how the medical profession began to consider ethical issues in the 1800s and subsequent developments in the 1900s. They then address the sociological, historical, ethical, and legal aspects of the practice of medicine. Later chapters discuss current and future challenges to medical ethics and professional values. Appendixes display various versions of the AMA's Code of Ethics as it has evolved over time. Contributors: George J. Annas, J.D., M.P.H., Arthur Isak Applbaum, Ph.D., Robert B.

Bioethicists function in an environment in which their peers - healthcare executives, lawyers, nurses, physicians - assert the integrity of their fields through codes of professional ethics. Is it time for bioethics to assert its integrity by developing a code of ethics? Answering in the affirmative, this paper lays out a case by reviewing the historical nature and function of professional codes of ethics. Arguing that professional codes are aggregative enterprises growing in response to a field's historical experiences, it asserts (...) that bioethics now needs to assert its integrity and independence and has already developed a body of formal statements that could be aggregated to create a comprehensive code of ethics for bioethics. A Draft Model Aggregated Code of Ethics for Bioethicists is offered in the hope that analysis and criticism of this draft code will promote further discussion of the nature and content of a code of ethics for bioethicists.

John Searle's Speech Acts (1969) and Expression and Meaning (1979) developed a highly original and influential approach to the study of language. But behind both works lay the assumption that the philosophy of language is in the end a branch of the philosophy of the mind: speech acts are forms of human action and represent just one example of the mind's capacity to relate the human organism to the world. The present book is concerned with these biologically fundamental capacities, (...) and, though third in the sequence, in effect it provides the philosophical foundations for the other two. Intentionality is taken to be the crucial mental phenomenon, and its analysis involves wide-ranging discussions of perception, action, causation, meaning, and reference. In all these areas John Searle has original and stimulating views. He ends with a resolution of the 'mind-body' problem. (shrink)

Techniques for achieving moral enhancement will modify brain processes to produce what is alleged to be more moral conduct. Neurophilosophy and neuroethics must ponder what “moral enhancement” could possibly be, if possible at all. Objections to the very possibility of moral enhancement, raised from various philosophical and neuroscientific standpoints, fail to justify skepticism, but they do place serious constraints on the kinds of efficacious moral enhancers. While there won't be a “morality pill,” and hopes for global moral enlightenment will remain (...) hopes, there will be a large variety of behavioral modifiers described as enhancers of some aspect of morality or another according to prevailing social norms. The most likely moral enhancers that will be designed, tested, and marketed in the near future will attempt to alleviate seriously immoral and illegal behavior. Some enhancers diminishing antisocial conduct and a few designed to elevate moral conduct above normal levels will also become available, although their widespread use is doubtful. There will also be specialized modifications for enhancing whatever an individual personally regards as moral, and for enabling better performance by a person in an operational role. A measure of skepticism toward all the proposed kinds of moral enhancement is advised, and where political implementation of moral enhancers is concerned, a healthy amount of cynicism as well.

This article investigates the potential of fMRI to test assumptions about different components in models of complex cognitive tasks. If the components of a model can be associated with specific brain regions, one can make predictions for the temporal course of the BOLD response in these regions. An event‐locked procedure is described for dealing with temporal variability and bringing model runs and individual data trials into alignment. Statistical methods for testing the model are described that deal with the scan‐to‐scan correlations (...) in the errors of measurement of the BOLD signal. This approach is illustrated using a “sacrificial” ACT‐R model that involves mapping 6 modules onto 6 brain regions in an experiment from Ravizza, Anderson, and Carter (in press) concerned with equation solving. The model's visual encoding predicted the BOLD response in the fusiform gyrus, its controlled retrieval predicted the BOLD response in the lateral inferior prefrontal cortex, and its subgoal setting predicted the BOLD response in the anterior cingulate cortex. On the other hand, its motor programming failed to predict anticipatory activation in the motor cortex, its representational changes failed to predicted the pattern of activity in the posterior parietal cortex, and its procedural component failed to predict an initial spike in caudate. The results illustrate the power of such data to direct the development of a theory of complex problem solving, both at the level of a specific task model as well as at the level of the cognitive architecture.

ABSTRACT:Intermediaries, such as accountants, lawyers, and bankers, are gatekeepers, which are parties whose cooperation is necessary for corporations to function and who, by withholding cooperation, are able to prevent significant corporate misconduct. The recent scandals at Enron and other corporations were due, in part, to failures by gatekeeper institutions. However, intermediaries exist primarily to provide for-fee services and not specifically to detect and deter misconduct. Insofar as these institutions are gatekeepers or guardians, they serve reluctantly. Hence the question: What is (...) the responsibility of intermediaries to act as gatekeepers? This article argues that the appropriate moral, as well as legal, principle for justifying responsibility in a gatekeeper role is cost effectiveness. This conclusion is reached by means of a hypothetical exercise called the investors’ bargain in which investors—who bear the costs and receive the benefits of intermediaries’ gatekeeper role—are asked to choose the best means of protecting their interests.

John R. Schneider explores the problem that animal suffering, caused by the inherent nature of Darwinian evolution, poses to belief in theism. Examining the aesthetic aspects of this moral problem, Schneider focuses on the three prevailing approaches to it: that the Fall caused animal suffering in nature (Lapsarian Theodicy), that Darwinian evolution was the only way for God to create an acceptably good and valuable world (Only-Way Theodicy), and that evolution is the source of major, God-justifying beauty (Aesthetic Theodicy). (...) He also uses canonical texts and doctrines from Judaism and Christianity - notably the book of Job, and the doctrines of the incarnation, atonement, and resurrection - to build on insights taken from the non-lapsarian alternative approaches. Schneider thus constructs an original, God-justifying account of God and the evolutionary suffering of animals. His book enables readers to see that the Darwinian configuration of animal suffering unveiled by scientists is not as implausible on Christian theism as commonly supposed. (shrink)

Anne Conway rejects the view that creatures are essentially members of any natural kind more specific than the kind 'creature'. That is, she rejects essentialism about species membership. This chapter provides an analysis of one of Anne Conway's arguments against such essentialism, which (as I argue) is drawn from metaethical rather than metaphysical premises. In her view, if a creature's species or kind were inscribed in its essence, that essence would constitute a limit on the creature's potential to participate in (...) the divine good. It is this consideration that ultimately leads her to reject essentialism about species membership. The chapter concludes with an examination of some of the metaethical consequences of Conway's view as well as a lesson it can teach us about ideal adviser accounts of the good. (shrink)

The human cognitive architecture consists of a set of largely independent modules associated with different brain regions. This book discusses in detail how these various modules can combine to produce behaviours as varied as driving a car and solving an algebraic equation.

In this collection of essays, written especially for this volume, many of the most prominent scholars on Dewey are inspired to search for that new enlightenment that Dewey himself sought, reconfigured to deal with the pressing problems of our times.

Can the output of human cognition be predicted from the assumption that it is an optimal response to the information-processing demands of the environment? A methodology called rational analysis is described for deriving predictions about cognitive phenomena using optimization assumptions. The predictions flow from the statistical structure of the environment and not the assumed structure of the mind. Bayesian inference is used, assuming that people start with a weak prior model of the world which they integrate with experience to develop (...) stronger models of specific aspects of the world. Cognitive performance maximizes the difference between the expected gain and cost of mental effort. Memory performance can be predicted on the assumption that retrieval seeks a maximal trade-off between the probability of finding the relevant memories and the effort required to do so; in categorization performance there is a similar trade-off between accuracy in predicting object features and the cost of hypothesis formation; in casual inference the trade-off is between accuracy in predicting future events and the cost of hypothesis formation; and in problem solving it is between the probability of achieving goals and the cost of both external and mental problem-solving search. The implemention of these rational prescriptions in neurally plausible architecture is also discussed. (shrink)
