When making decisions, humans can observe many kinds of information about others' activities, but their effects on performance are not well understood. We investigated social learning strategies using a simple problem-solving task in which participants search a complex space, and each can view and imitate others' solutions. Results showed that participants combined multiple sources of information to guide learning, including payoffs of peers' solutions, popularity of solution elements among peers, similarity of peers' solutions to their own, and relative payoffs from (...) individual exploration. Furthermore, performance was positively associated with imitation rates at both the individual and group levels. When peers' payoffs were hidden, popularity and similarity biases reversed, participants searched more broadly and randomly, and both quality and equity of exploration suffered. We conclude that when peers' solutions can be effectively compared, imitation does not simply permit scrounging, but it can also facilitate propagation of good solutions for further cumulative exploration.

The nature of measurement is a topic of central concern in the philosophy of science and, indeed, measurement is the essential link between science and mathematics. Professor Ellis's book, originally published in 1966, is the first general exposition of the philosophical and logical principles involved in measurement since N. R. Campbell's Principles of Measurement and Calculation, and P. W. Bridgman's Dimensional Analysis. Professor Ellis writes from an empiricist standpoint. His object is to distinguish and define the basic concepts in measurement, (...) for example: scale, quantity, unit. dimension, number and probability. He discusses the problem of classifying scales of measurement and the special logical problems associated with each kind of scale. A translation of mach's Critique on the Concept of Temperature, which gives his views on the nature of measurement more fully than in any of his other works, is given as an appendix. (shrink)

Addressing both collegiate and professional sports, the updated edition of Fair Play: The Ethics of Sport explores the ethical presuppositions of competitive athletics and their connection both to ethical theory and to concrete moral dilemmas that arise in actual athletic competition. This fourth edition has been updated with new examples, including a discussion of Spygate by the New England Patriots and recent discoveries on the use of performance enhancing drugs by top athletes. Two additional authors, Cesar R. Torres and Peter (...) F. Hager, bring to this edition a discussion of the moral issues involved in youth sports and the ethics of being a fan, as well as a fresh perspective on the theories of broad internalism and the quest for excellence. Furthermore, major criticisms of broad internalism by philosophers William J. Morgan and Scott Kretchmar add a new dimension to the discussion on the moral foundations of winning. (shrink)

Contemporary scientific theories assume a primarily micro-deterministic view of nature. This paper explores the question of whether micro-determinism is incompatible with the alleged emergence of properties and laws that some biologists and philosophers assert occurs in various biological systems. I argue that a preferable unified treatment of these emergence claims takes properties, rather than laws, to be the units of emergence. Four distinct conceptions of emergence are explored and three shown to be compatible with micro-determinism. The remaining concept of emergence, (...) direct macro-determination, does not, I argue, meet the general requirement that an adequate scientific explanation provide a coherent mechanism or effective means of determination.

Use of the concept of `areasonable person and his or her expectations'is widely found in legal reasoning. This legalconstruct is employed in the present article toexamine privacy questions associated withcontemporary information technology, especiallythe internet. In particular, reasonableexpectations of privacy while browsing theworld-wide-web and while sending and receivinge-mail are analyzed.

This article offers a critique of research practices typical of experimental philosophy. To that end, it presents a review of methodological issues that have proved crucial to the quality of research in the biobehavioral sciences. It discusses various shortcomings in the experimental philosophy literature related to (1) the credibility of self-report questionnaires, (2) the validity and reliability of measurement, (3) the adherence to appropriate procedures for sampling, random assignment, and handling of participants, and (4) the meticulousness of study reporting. It (...) argues that the future standing of experimental philosophy will hinge upon improvements in research methods. (shrink)

The threat to the survival of humankind posed by nuclear weapons has been a frightening and essential focus of public debate for the last four decades and must continue to be so if we are to avoid destroying ourselves and the natural world around us. One unfortunate result of preoccupation with the nuclear threat, however, has been a new kind of "respectability" accorded to conventional war. In this radical and cogent argument for pacifism, Robert Holmes asserts that all war--not (...) just nuclear war--has become morally impermissible in the modern world. Addressing a wide audience of informed and concerned readers, he raises dramatic questions about the concepts of "political realism" and nuclear deterrence, makes a number of persuasive suggestions for nonviolent alternatives to war, and presents a rich panorama of thinking about war from St. Augustine to Reinhold Niebuhr and Herman Kahn. Holmes's positions are compellingly presented and will provoke discussion both among convinced pacifists and among those whom he calls "militarists." "Militarists," we realize after reading this book, include the majority of us who live a friendly and peaceful personal life while supporting a system which, if Holmes is correct, guarantees war and risks eventual human extinction. Originally published in 1989. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press.

This volume provides a wide-ranging and lucid introduction to the major ethical theories found in the history of Western philosophy.

A standard objection to act utilitarian theories is that they are not helpful in deciding what it is morally permissible for us to do when we actually have to make a choice between alternatives. That is, such theories are worthless as decision procedures. A standard reply to this objection is that act utilitarian theories can be evaluated solely as theories about right-making characteristics and, when so evaluated, their inadequacy as decision procedures is irrelevant. Even if somewhat unappealing, this is an (...) effective reply to the standard objection. (shrink)

This unique study brings together for the first time two of the most important philosophers of this century. Never before have these two thinkers been compared - and commentators' opinions on their relationship differ greatly. Are the views of Wittgenstein and Quine on method and the nature of philosophy comparable or radically opposed? Does Wittgenstein's concept of language engender that of Quine, or threaten its philosophical foundations? An understanding of the similarities and differences between the thought of Wittgenstein and of (...) Quine is essential if we are to have a full picture of contemporary philosophy. This collection of essays offers diverse and original ways in which to view their relationship. (shrink)

Advertisers often have been accused of using techniques which manipulate and control the behavior of consumers and hence violate their autonomy. Some of these techniques are puffery, subliminal advertising, and indirect information transfer. After examining both criticisms and defenses of such practices, this paper presents an analysis of four of the concepts involved in the debate — the concepts of autonomous desire, rational desire, free choice, and control. Applying the results to the case of advertising, it is shown that advertising (...) cannot be found guilty of intrinsically or frequently violating the consumer's autonomy in any of the relevant senses of this notion.

Many writers have attempted to develop criteria to demarcate between competent science and pseudo?science. Such attempts can be aimed at sizeable, organized endeavours, such as mesmerism and astrology, or at the level of individual practice. The latter is seen by some, such as Lugg, as more likely to be feasible and useful. This paper argues that parapsychology, due to its complexity and diversity, illustrates some of the problems of attempting to develop demarcation criteria for extensive endeavours. It is also suggested (...) that parapsychology may offer a productive ground for testing whether demarcation criteria can be successfully applied to practices in respect of predicting which will succeed and which will not. The conclusion is that, for demarcation efforts to be useful, they should pass some of their own criteria, such as falsifiability. (shrink)

Novice designers produced a sequence of sketches while inventing a logo for a novel brand of soft drink. The sketches were scored for the presence of specific objects, their local features and global composition. Self‐assessment scores for each sketch and art critics' scores for the end products were collected. It was investigated whether the design evolves in an essentially random fashion or according to an overall heuristic. The results indicated a macrostructure in the evolution of the design, characterized by two (...) stages. For the majority of participants, the first stage is marked by the introduction and modification of novel objects and their local and global aspects; the second stage is characterized by changes in their global composition. The minority that showed the better designs has a different strategy, in which most global changes were made in the beginning. Although participants did not consciously apply these strategies, their self‐assessment scores reflect the stages of the process. (shrink)

How did the human brain evolve so that consciousness of art could develop? In The Psychology of Art and the Evolution of the Conscious Brain, Robert Solso describes how a consciousness that evolved for other purposes perceives and creates art.Drawing on his earlier book Cognition and the Visual Arts and ten years of new findings in cognitive research, Solso shows that consciousness developed gradually, with distinct components that evolved over time. One of these components is an adaptive consciousness that (...) includes the ability to imagine objects that are not present--an ability that allows us to create visual art.Solso describes the neurological, perceptual, and cognitive sequence that occurs when we view art, and the often inexpressible effect that a work of art has on us. He shows that there are two aspects to viewing art: nativistic perception--the synchronicity of eye and brain that transforms electromagnetic energy into neuro-chemical codes--which is "hard-wired" into the sensory-cognitive system; and directed perception, which incorporates personal history and knowledge--the entire set of our expectations and past experiences. Both forms of perception are part of the appreciation of art, and both are products of the evolution of the conscious brain over hundreds of thousands of years.Solso also investigates the related issues of neurological and artistic perception of the human face, the effects of visual illusions, and the use of perspective. The many works of art used as examples are drawn from a wide range of artistic traditions, from ancient Egypt to Africa and India and the European Renaissance. (shrink)

Both theoretical and empirical work in a variety of disciplines has resulted in a recent turn away from Cartesian and Meadian anthropocentrism in the direction of a radical reconsideration of nonhuman animal mind and agency. Central to sociology’s role in envisioning a repopulated social world is the analysis of nonhuman-human social interaction. Because all social action is predicated on certain assumptions regarding the minds of others, a theory of intersubjectivity must be at the core of any such project. It is (...) argued here that the key elements employed in Alfred Schutz’s conceptualization of intersubjectivity among humans are also demonstrated in the routine communicative projects of humans and their companion animals. After presenting a Schutzian theory of intersubjectivity, this article analyzes, from an ethnographic perspective, elements of the everyday lifeworld Rocky—a deaf, paraplegic cat—cohabits with the author and other family members. Through that analysis, the paper demonstrates that the dynamics of everyday interactions through which Rocky actively participates in the creation of meaning and the achievement of understanding is highly consistent with Schutz’s theory of human intersubjectivity.

Agriculture’s dominant focus is feeding the human population. From an ethical perspective, this is clearly very positive, but it does not absolve agriculture from critical, ethical examination of the totality of agriculture’s effects. To earn the public’s ongoing support, agriculture must be trusted to vigilantly examine its full range of effects and be sure they align with the highest ethical values. Agriculture’s record is enviable in the science and technology associated with its primary ethical concern, but we need to do (...) more to address the broader ethical issues that are the public’s increasing concern. The entire agricultural community needs to become engaged in the discussion. The classroom offers an effective starting place. Yet, curricular offerings are rarely available at public universities. Opportunity for ethics study should become a key component of agricultural education. (shrink)

Increasingly, US-sponsored research is carried out in developing countries, but how US Institutional Review Boards (IRBs) approach the challenges they then face is unclear.METHODS: I conducted in-depth interviews of about 2 hours each, with 46 IRB chairs, directors, administrators and members. I contacted the leadership of 60 IRBs in the United States (US) (every fourth one in the list of the top 240 institutions by National Institutes of Health (NIH) funding), and interviewed IRB leaders from 34 (55%).RESULTS: US IRBs face (...) ethical and logistical challenges in interpreting and applying principles and regulations in developing countries, given economic and health disparities, and limited contextual knowledge. These IRBs perceive wide variations in developing world IRBs/RECs' quality, resources and training; and health systems in some countries may have long-standing practices of corruption. These US IRBs often know little of local contexts, regulations and standards of care, and struggle with understandings of other cultures' differing views of autonomy, and risks and benefits of daily life. US IRBs thus face difficult decisions, including how to interpret principles, how much to pay subjects and how much sustainability to require from researchers. IRB responses and solutions include trying to maintain higher standards for developing world research, obtain cultural expertise, build IRB infrastructure abroad, communicate with foreign IRBs, and ‘negotiate’ for maximum benefits for participants and fearing ‘worst-case scenarios’.CONCLUSIONS: US and foreign IRBs confront a series of tensions and dilemmas in reviewing developing world research. These data have important implications for increased education of IRBs/RECs and researchers in the US and abroad, and for research and practice. (shrink)

The very expertise with which psychologists wield their tools for achieving laboratory control may have had the unwelcome effect of blinding psychologists to the possibilities of discovering principles of behavior without conducting experiments. When creatively interrogated, a diverse range of large, real-world data sets provides powerful diagnostic tools for revealing principles of human judgment, perception, categorization, decision-making, language use, inference, problem solving, and representation. Examples of these data sets include patterns of website links, dictionaries, logs of group interactions, collections of (...) images and image tags, text corpora, history of financial transactions, trends in twitter tag usage and propagation, patents, consumer product sales, performance in high-stakes sporting events, dialect maps, and scientific citations. The goal of this issue is to present some exemplary case studies of mining naturally existing data sets to reveal important principles and phenomena in cognitive science, and to discuss some of the underlying issues involved with conducting traditional experiments, analyses of naturally occurring data, computational modeling, and the synthesis of all three methods.

This fine book tells an important story of how long-standing notions about the body as dominated by spirit-like humors were transformed into scientific descriptions of its solid tissues. Vesalius, Harvey, Descartes, Willis, and Locke all played roles in this transformation, as the cerebral hemispheres and cranial nerves began to take precedence over the role of spirit, passion, and the heart in human thought and behavior. Non of this occurred in a social vacuum, and the book describes the historical context clearly. (...) It also shows how debates over investigative methods and models of body order that first raged over 300 years ago continue to influence biomedicine and the broader culture today. No other book on western mind-body relationships has attempted this. (shrink)
