Predictable somatosensory feedback leads to a reduction in tactile sensitivity. This phenomenon, called tactile suppression, relies on a mechanism that uses an efference copy of motor commands to help select relevant aspects of incoming sensory signals. We investigated whether tactile suppression is modulated by the task-relevancy of the predicted consequences of movement and the intensity of related somatosensory feedback signals. Participants reached to a target region in the air in front of a screen; visual or tactile feedback indicated the reach (...) was successful. Furthermore, tactile feedback intensity varied across two groups of participants. We measured tactile suppression by comparing detection thresholds for a probing vibration applied to the finger either early or late during reach and at rest. As expected, we found an overall decrease in late-reach suppression, as no touch was involved at the end of the reach. We observed an increase in the degree of tactile suppression when strong tactile feedback was given at the end of the reach, compared to when weak tactile feedback or visual feedback was given. Our results suggest that the extent of tactile suppression can be adapted to different demands of somatosensory processing. Downregulation of this mechanism is invoked only when the consequences of missing a weak movement sequence are severe for the task. The decisive factor for the presence of tactile suppression seems not to be the predicted action effect as such, but the need to detect and process anticipated feedback signals occurring during movement.

The sixteen essays in Gender Struggles address a wide range of issues in gender struggles, from the more familiar ones that, for the last thirty years, have been the mainstay of feminist scholarship, such as motherhood, beauty, and sexual violence, to new topics inspired by post-industrialization and multiculturalism, such as the welfare state, cyberspace, hate speech, and queer politics, and finally to topics that traditionally have not been seen as appropriate subjects for philosophizing, such as adoption, care work, and the (...) home.

Stereotype threat—a situational context in which individuals are concerned about confirming a negative stereotype—is often shown to impact test performance, with one hypothesized mechanism being that cognitive resources are temporarily co-opted by intrusive thoughts and worries, leading individuals to underperform despite high content knowledge and ability. We test here whether stereotype threat may also impact initial student learning and knowledge formation when experienced prior to instruction. Predominantly African American fifth-grade students provided either their race or the date before a videotaped, (...) conceptually demanding mathematics lesson. Students who gave their race retained less learning over time, enjoyed the lesson less, reported a diminished desire to learn more, and were less likely to choose to engage in an optional math activity. The detrimental impact was greatest among students with high baseline cognitive resources. While stereotype threat has been well documented to harm test performance, the finding that effects extend to initial learning suggests that stereotype threat's contribution to achievement gaps may be greatly underestimated.

Leech et al.'s model proposes representing relations as primed transformations rather than as structured representations (explicit representations of relations and their roles dynamically bound to fillers). However, this renders the model unable to explain several developmental trends (including relational integration and all changes not attributable to growth in relational knowledge). We suggest looking to an alternative computational model that learns structured representations from examples.

Language plays a role in the genocide of the Rohingya people in Myanmar and continues to shape their experiences in displacement, yet their linguistic rights are rarely discussed in relation to their human rights and humanitarian concerns. International human rights standards offer important foundations for conceptualizing the “right to language” and identifying how linguistic rights can be violated both in situ and in displacement. The Rohingya case highlights how language policies are weaponized to oppress unwanted minorities; their outsider status is (...) reinforced by the country’s language education policy and they face additional rights challenges in displacement—including obstacles to effectively accessing humanitarian aid. Moving forward, norms associated with self-determination and language rights offer a conceptual foundation for shifting attitudes and altering negative perceptions of Rohingya identity. (shrink)

Relational reasoning is a hallmark of human higher cognition and creativity, yet it is notoriously difficult to encourage in abstract tasks, even in adults. Generally, young children initially focus more on objects, but with age become more focused on relations. While prerequisite knowledge and cognitive resource maturation partially explains this pattern, here we propose a new facet important for children's relational reasoning development: a general orientation to relational information, or a relational mindset. We demonstrate that a relational mindset can be (...) elicited, even in 4‐year‐old children, yielding greater than expected spontaneous attention to relations. Children either generated or listened to an experimenter state the relationships between objects in a set of formal analogy problems, and then in a second task, selected object or relational matches according to their preference. Children tended to make object mappings, but those who generated relations on the first task selected relational matches more often on the second task, signaling that relational attention is malleable even in young children.

Research into mathematics often focuses on basic numerical and spatial intuitions, and one key property of numbers: their magnitude. The fact that mathematics is a system of complex relationships that invokes reasoning usually receives less attention. The purpose of this special issue is to highlight the intricate connections between reasoning and mathematics, and to use insights from the reasoning literature to obtain a more complete understanding of the processes that underlie mathematical cognition. The topics that are discussed range from the (...) basic heuristics and biases to the various ways in which complex, effortful reasoning contributes to mathematical cognition, while also considering the role of individual differences in mathematics performance. These investigations are not only important at a theoretical level, but they also have broad and important practical implications, including the possibility to improve classroom practices and educational outcomes, to facilitate people's decision-making, as well as the clear and accessible communication of numerical information.

Many large corporations now have written codes of ethics to guide the business/marketing activities of employees. The purpose of this study was to determine the frequency and types of topics which are covered in the ethics policy statements of large U.S. corporations. The results indicated that the topics covered most often (respectively) were: misuse of funds/improper accounting, conflicts of interest, political contributions, and confidential information. It is concluded that in addition to written ethics policy statements, top management should communicate ethical (...) values and demonstrate by example. (shrink)

Second harmonic generating (SHG) nanoprobes have recently emerged as versatile and durable labels suitable for in vivo imaging, circumventing many of the inherent drawbacks encountered with classical fluorescent probes. Since their nanocrystalline structure lacks a central point of symmetry, they are capable of generating second harmonic signal under intense illumination – converting two photons into one photon of half the incident wavelength – and can be detected by conventional two‐photon microscopy. Because the optical signal of SHG nanoprobes is based on (...) scattering, rather than absorption as in the case of fluorescent probes, they neither bleach nor blink, and the signal does not saturate with increasing illumination intensity. When SHG nanoprobes are used to image live tissue, the SHG signal can be detected with little background signal, and they are physiologically inert, showing excellent long‐term photostability. Because of their photophysical properties, SHG nanoprobes provide unique advantages for molecular imaging of living cells and tissues with unmatched sensitivity and temporal resolution. (shrink)

We present this special issue on positive organizational ethics (POE) to highlight those pursuing positive subjective experiences, positive attributes of individuals and groups, and positive practices that contribute to ethical and virtuous behavior in organizations. Although prior research has offered some insight in this area, there is still much to be learned about how to cultivate and sustain ethical strength in different types of organizations and how goodness can emerge from and in spite of human failings. After describing the positive (...) movement, we position POE as a discrete area of inquiry within the broader positive behavioral sciences, at the intersection of positive behavioral studies and business ethics. After defining our terms and purpose for creating the POE domain, we introduce the articles in this special issue. The introduction concludes with suggested topics for future research. (shrink)

Religion is often understood to play a positive role in shaping moral attitudes among believers. We assessed the relationship between church members’ levels of felt connectedness to their respective congregations and perceived similarity in personal and congregational moral values, and whether there was a relationship between these and the amount of time spent in synchronous movement or singing during worship. The similarity between personal and perceived congregational moral importance was correlated with feelings of closeness to one’s congregation but not by (...) the amount of time spent in synchronous movement or singing. Differences in moral foundations scores and in moral importance of specific issues were found between different theological traditions. These findings demonstrate that, for churchgoers, there is a relationship between the use of music or synchronous movement in a church service and feelings of social bonding and there is also a relationship between the degree to which churchgoers identify with their church community and the degree to which they believe their priorities match those of their church. Furthermore, differences in theological tradition appear to be reflected in differences in moral values. (shrink)

This chapter presents the text of a lecture on Buddhist archaeology in Republican China given at the British Academy's 2008 Elsley Zeitlyn Lecture on Chinese Archaeology and Culture.

Based upon the Decision Field Theory (Busemeyer and Townsend 1993), we tested a model of dynamic reasoning to predict the effect of time pressure on analytical and experiential processing during decision-making. Forty-six participants were required to make investment decisions under four levels of time pressure. In each decision, participants were presented with experiential cues which were either congruent or incongruent with the analytical information. The congruent/incongruent conditions allowed us to examine how many decisions were based upon the experiential versus the (...) analytical information, and to see if this was affected by the varying degrees of time pressure. As expected, the overall accuracy was reduced with greater time pressure and accuracy was higher when the experiential and analytical cues were congruent than when they were incongruent. Of great interest was the data showing that under high time pressure participants used more experiential cues than at other time pressures. We suggest that the dynamic reasoning paradigm has some future potential for predicting the effects of experiential biases in general, and specifically under time pressure. (shrink)

Behavioral evidence for the COVIS dual‐process model of category learning has been widely reported in over a hundred publications (Ashby & Valentin, ). It is generally accepted that the validity of such evidence depends on the accurate identification of individual participants' categorization strategies, a task that usually falls to Decision Bound analysis (Maddox & Ashby, ). Here, we examine the accuracy of this analysis in a series of model‐recovery simulations. In Simulation 1, over a third of simulated participants using an (...) Explicit (conjunctive) strategy were misidentified as using a Procedural strategy. In Simulation 2, nearly all simulated participants using a Procedural strategy were misidentified as using an Explicit strategy. In Simulation 3, we re‐examined a recently reported COVIS‐supporting dissociation (Smith et al., ) and found that these misidentification errors permit an alternative, single‐process, explanation of the results. Implications for due process in the future evaluation of dual‐process theories, including recommendations for future practice, are discussed. (shrink)

The concepts of particular and universal have grown so familiar that their significance has become difficult to discern, like coins that have been passed back and forth too many times, worn smooth so their values can no longer be read. On the Genealogy of Universals seeks to overcome our sense of over-familiarity with these concepts by providing a case study of their evolution during the late nineteenth century and early twentieth century, a study that shows how the history of these (...) concepts is bound up with the origins and development of analytic philosophy itself. Understanding how these concepts were taken up, transfigured, and given up by the early analytic philosophers, enables us to recover and reanimate the debate amongst them that otherwise remains Delphic. This book begins from the early, originating texts of analytic philosophy that have hitherto baffled commentators, including Moore's early papers, and engages afresh with the neglected contributions of philosophical figures that historians of analytic philosophy have mostly since forgotten, including Stout and Whitehead. This sheds new light upon the relationships of Moore to Russell, Russell to Wittgenstein, and Wittgenstein to Ramsey. (shrink)

Each text on its own provides a very good initial evaluation of contemporary conversations in health care ethics. Together they provide a thorough foundation for the study of health care ethics that encourages further exploration of topics in the field. They both provide an excellent overview for undergraduate students as well as anyone interested in the field of medical morality.Health Care Ethics is especially helpful for those entering the field of ethics in general and the more particular realm of medical morality. User-friendly, [End Page 211] the book is accessible to beginners while also being relevant to those already well-versed in medical ethics. The book provides case studies culled from the experiences of the authors throughout their careers in the practice of medical ethics. Perhaps even more useful, however, are the other exercises in which readers are given the opportunity to actively engage the text in order to discover and more fully articulate their own moral stance. Although Health Care Ethics approaches the topic from a theological perspective, using scriptural passages as well as broader religious themes and contexts, the book is accessible to those outside of the religious arena as well.The first three chapters lay the framework for general theological and ethical inquiry while the later chapters discuss more specific topics in applied health care ethics. The opening chapters by Michael Panicola are thought-provoking, especially since they encourage readers to participate in exercises to determine how they would respond to particular scenarios in their personal decision making. For example, after laying out the classic ethical theories, readers are asked to take a “quiz” by responding to multiple-choice questions to determine how they would respond to various ethical situations. The exercise demonstrates that moral discernment that relies on one ethical theory alone or one single approach to ethics is too narrow and confining for authentic dialogue in ethics. Another exercise calls upon readers to examine their fundamental bases for personal decision making by asking them to create a list of what they think are the ten things that constitute human flourishing and then narrow that list down to the top two. In addition to being engaging, these exercises help readers establish their personal moral stance by asking them to appropriate foundational norms in the process of moral discernment to the case studies throughout the book. They also help readers apply these norms to the specific topics in health care ethics presented in the later chapters.The authors of Health Care Ethics clearly identify human flourishing as the center and goal for all ethical inquiry. Demonstrating that “human flourishing” has different connotations for different people, they also argue that certain norms can be agreed upon to establish a framework for all conversations regarding moral decision making in health care. They especially emphasize a concern for the optimization of human flourishing in final chapters of the text. Chapters 4–12 provide detailed examinations of current topics in medical ethics. Each chapter includes case studies that raise questions concerning social ethics as well as health care morality, employing sources from law, sociology, philosophy, and theology. Each case underscores the complexity of moral decision making in health care ethics as well as the point that there is no one, pure approach to medical ethics that... (shrink)

The present state of ethical theory and practice is disquieting. Objectivism, in all its varieties, is unconvincing, and subjectivism, hedonic or emotive, is intellectually incredible and socially intolerable. No one is ethically content—except the dogmatist and the sceptic, who act willy nilly with the exponents of “might-cum-persuasion makes right.” Can we find a happier middle region between these inhospitable poles? Perhaps the very limitations of human valuation will provide the ground that ethics requires. Let us begin by considering the conditions (...) which must hold if ethical action is to be possible: 1. Only if the agent can provide a justifying reason for his choice of action can he claim to act ethically. For ethical action is a species of purposive action, and to act purposively entails the ability to give justifying reasons for one's choice of action. . Thus ethical action presupposes putatively grounded ethical judgment. 2. Justifying reasons must be acknowledgeable by all competent judges, i.e. by all persons who are acquainted with all relevant knowledge of the nature and consequences of the alternative courses of action, allow as far as possible for congenital, cultural and idiosyncratic bias, are capable of sane and serious reflection, and are able to make survey of their experience and to draw conclusions from it. For the judgment “the action A is ethically preferable to its alternatives B ” entails “A ought to be done” which in turn entails “every competent judge is capable of acknowledging the ground of the judgment ‘A is ethically preferable to B’ and consequently would be able to set himself to perform A as an ethical act, .” We can assure ourselves of this requirement of acknowledgeability by observing that whenever we resolve, and not merely settle, an ethical disagreement, we have achieved not only a factual, predictive, valuational and attitudinal agreement between the disputants, but a joint acknowledgment of the ground of the ethical judgment. Without this, the agreement could not be said to be ethical, whether the judgment be right or wrong or neither, but merely an agreement to disagree, ethically. Unless ethical disagreement is in principle resolvable, ethical judgment is impossible, for we should be unable to claim that our choice ought to be acted upon. (shrink)

According to philosophical folklore Ramsey maintained three propositions in his famous 1925 paper “Universals”: (i) there is no subject-predicate distinction; (ii) there is no particular-universal distinction; (iii) there is no particular-universal distinction because there is no subject-predicate distinction. The ‘first generation’ of Ramsey commentators dismissed “Universals” because they held that whereas predicates may be negated, names may not and so there is a subject-predicate distinction after all. The ‘second generation’ of commentators dismissed “Universals because they held that the absence of (...) a merely linguistic distinction between subject and predicate does not provide any kind of reason for doubting that a truly ontological (i.e. non-linguistic) distinction obtains between particulars and universals. But both first and second-generation criticisms miss their marks because Ramsey did not maintain the three identified propositions. The failure of commentators to appreciate the point and purpose of the position Ramsey actually advanced in “Universals” results from (a) failing to consider the range of different arguments advanced there, (b) looking at “Universals” in isolation from Ramsey’s other papers and (c) failing to consider Ramsey’s writings in the context of the views that Russell and Wittgenstein held during the early 1920s. Seen from this wider perspective Ramsey arguments in “Universals” take on an altogether different significance. They not only anticipate important contemporary developments⎯the resurgence of Humeanism and the doctrine that the existence of universals can only be established a posteriori⎯but also point beyond them.

Neste Ano Internacional da Biodiversidade, reflito sobre as responsabilidades crescentes das entidades religiosas no contexto atual da Crise Ambiental. Faço uma retrospectiva sobre a origem evolutiva das religiões no contexto da evolução cultural do homem. Em seguida, menciono algumas dimensões ecológicas do pensamento religioso, significativas para os problemas ambientais. Paradigmas religiosos se originam de forma semelhante aos das ciências. As doutrinas sociais das igrejas, especialmente a igreja católica, estabelecem compromissos com os excluídos e promovem o desenvolvimento integral da pessoa humana, (...) buscando justiça social e econômica. Isto tem implicações para o equilíbrio ecológico e para o futuro da humanidade. Sugiro que as igrejas atuem mais intensamente, de forma integrada com a ciência, na intermediação política em prol da solução dos problemas ambientais. A moral religiosa ajudaria a reverter os ganhos econômicos advindos da utilização sustentável da biodiversidade genética para as culturas locais. Também antevejo um papel maior na conscientização das comunidades sobre os benefícios de uma vida equilibrada com a natureza e de uma exploração racional dos recursos naturais. A preservação da biodiversidade constitui uma questão moral de cuja conscientização e regulamentação legal urgentíssima dependemos para a sobrevivência dos ecossistemas naturais e da própria espécie humana. Palavras-chave: Evolução Cultural; Religião; Crise da Biodiversidade; Política Ambiental; Papel da Igreja.In this International Year for the Conservation of Biodiversity, I reflect on the increasing responsibilities of religious entities towards solving the present Environmental Crisis. I provide a retrospect on the debate over the origin of religions in the context of the cultural evolution of man. I then mention some ecological dimensions of religious thinking, which are particularly significant for approaching environmental problems. Religious paradigms originate in ways that are similar to those in science. The social doctrines of churches establish compromises for excluded groups and promote the unabridged development of the human individual, which includes social and economic justice. This has implications for the ecological balance of nature and for the future of humanity. I suggest that the Church should act more intensely, integrated with science, in the political intermediation that searches for solutions for our environmental problems. Religious morality could help to restore the economical benefits resulting from the sustainable use of genetic biodiversity to local cultures. I also foresee a larger role of the church in promoting human perceptions regarding the benefits involved in obtaining a more sustainable relationship with nature and in promoting a more rational exploitation of natural resources. The conservation of biodiversity represents a moral matter demanding urgent legislation for the survival of natural ecosystems and, ultimately, of the human species. Key words : Cultural Evolution; Religion; Biodiversity Crisis; Environmental Crisis; Role of Church. (shrink)

Is there a particular‐universal distinction? Ramsey famously advocated scepticism about this distinction. In “Some Formal Ontological Relations” E.J.

But in defence of Ramsey I argue that the case remains to be made in favour of either the four‐fold ontology Lowe recommends or the articulation of a particular‐universal distinction within it.

In 1901 Russell had envisaged the new analytic philosophy as uniquely systematic, borrowing the methods of science and mathematics. A century later, have Russell’s hopes become reality? David Lewis is often celebrated as a great systematic metaphysician, his influence proof that we live in a heyday of systematic philosophy. But, we argue, this common belief is misguided: Lewis was not a systematic philosopher, and he didn’t want to be. Although some aspects of his philosophy are systematic, mainly his pluriverse of (...) possible worlds and its many applications, that systematicity was due to the influence of his teacher Quine, who really was an heir to Russell. Drawing upon Lewis’s posthumous papers and his correspondence as well as the published record, we show that Lewis’s non- Quinean influences, including G.E. Moore and D.M. Armstrong, led Lewis to an anti- systematic methodology which leaves each philosopher’s views and starting points to his or her own personal conscience. (shrink)

G. F. Stout is famous as an early twentieth century proselyte for abstract particulars, or tropes as they are now often called. He advanced his version of trope theory to avoid the excesses of nominalism on the one hand and realism on the other. But his arguments for tropes have been widely misconceived as metaphysical, e.g. by Armstrong. In this paper, I argue that Stout’s fundamental arguments for tropes were ideological and epistemological rather than metaphysical. He moulded his scheme to (...) fit what is actually given to us in perception, arguing that our epistemic practices would break down in an environment where only universals were given to us.

Mohism was an ancient Chinese philosophical movement founded in the fifth century B.C.E. by the charismatic artisan Mozi, or "Master Mo." The Mohists advanced a consequentialist ethics that anticipated Western utilitarianism by more than two thousand years and developed fascinating logical, epistemological, and political theories that set the terms of philosophical debate in China for generations. They were the earliest thinkers to outline a just war doctrine and to explain the origin of government from a state of nature. Their epistemology (...) and psychology provide intriguing alternatives to contemporary Western mentalism. The Philosophy of the Mozi is an extensive study of Mohism that immerses readers in the Mohist worldview, situates the movement's rise and decline within Chinese history, and highlights its relevance to modern thought.

Further arguments are offered in defence of the position that the variant of quantum field theory (QFT) that should be subject to interpretation and foundational analysis is axiomatic quantum field theory. I argue that the successful application of renormalization group (RG) methods within alternative formulations of QFT illuminates the empirical content of QFT, but not the theoretical content. RG methods corroborate the point of view that QFT is a case of the underdetermination of theory by empirical evidence. I also urge (...) caution in extrapolating interpretive conclusions about QFT from the application of RG methods in other contexts (e.g., condensed matter physics). This paper replies to criticisms advanced by David Wallace, but aims to be self-contained. (shrink)

Quantum field theory (QFT) presents a genuine example of the underdetermination of theory by empirical evidence. There are variants of QFT—for example, the standard textbook formulation and the rigorous axiomatic formulation—that are empirically indistinguishable yet support different interpretations. This case is of particular interest to philosophers of physics because, before the philosophical work of interpreting QFT can proceed, the question of which variant should be subject to interpretation must be settled. New arguments are offered for basing the interpretation of QFT (...) on a rigorous axiomatic variant of the theory. The pivotal considerations are the roles that consistency and idealization play in this case. *Received June 2009; revised August 2009. †To contact the author, please write to: Department of Philosophy, University of Waterloo, 200 University Avenue West, Waterloo, ON N2L 3G1, Canada; e‐mail: [email protected].
