The phenomenon of ambiguity aversion, in which risky gambles with known probabilities are preferred over ambiguous gambles with unknown probabilities, has been thoroughly documented in adults but never measured in children. Here, we use two distinct tasks to investigate ambiguity preferences of children (8- to 9-year-olds) and a comparison group of adults (19- to 27-year-olds). Across three separate measures, we found evidence for significant ambiguity aversion in adults but not in children and for greater ambiguity aversion in adults compared to (...) children. As ambiguity aversion in adults has been theorized to result from a preference to bet on the known and avoid the unfamiliar, we separately measured familiarity bias and found that children, like adults, are biased towards the familiar. Our findings indicate that ambiguity aversion emerges across the course of development between childhood and adolescence, while a familiarity bias is already present in childhood. (shrink)

Children bring intuitive arithmetic knowledge to the classroom before formal instruction in mathematics begins. For example, children can use their number sense to add, subtract, compare ratios, and even perform scaling operations that increase or decrease a set of dots by a factor of 2 or 4. However, it is currently unknown whether children can engage in a true division operation before formal mathematical instruction. Here we examined the ability of 6- to 9-year-old children and college students to perform symbolic (...) and non-symbolic approximate division. Subjects were presented with non-symbolic or symbolic dividends ranging from 32 to 185, and non-symbolic divisors ranging from 2 to 8. Subjects compared their imagined quotient to a visible target quantity. Both children and adults were successful at the approximate division tasks in both dots and numeral formats. This was true even among the subset of children that could not recognize the division symbol or solve simple division equations, suggesting intuitive division ability precedes formal division instruction. For both children and adults, the ability to divide non-symbolically mediated the relation between Approximate Number System acuity and symbolic math performance, suggesting that the ability to calculate non-symbolically may be a mechanism of the relation between ANS acuity and symbolic math. Our findings highlight the intuitive arithmetic abilities children possess before formal math instruction. (shrink)

Previous research reported that college students' symbolic addition and subtraction fluency improved after training with non-symbolic, approximate addition and subtraction. These findings were widely interpreted as strong support for the hypothesis that the Approximate Number System (ANS) plays a causal role in symbolic mathematics, and that this relation holds into adulthood. Here we report four experiments that fail to find evidence for this causal relation. Experiment 1 examined whether the approximate arithmetic training effect exists within a shorter training period than (...) originally reported (2 vs 6 days of training). Experiment 2 attempted to replicate and compare the approximate arithmetic training effect to a control training condition matched in working memory load. Experiments 3 and 4 replicated the original approximate arithmetic training experiments with a larger sample size. Across all four experiments (N = 318) approximate arithmetic training was no more effective at improving the arithmetic fluency of adults than training with control tasks. Results call into question any causal relationship between approximate, non-symbolic arithmetic and precise symbolic arithmetic. (shrink)

The dual-code proposal of number representation put forward by Cohen Kadosh & Walsh (CK&W) accounts for only a fraction of the many modes of numerical abstraction. Contrary to their proposal, robust data from human infants and nonhuman animals indicate that abstract numerical representations are psychologically primitive. Additionally, much of the behavioral and neural data cited to support CK&W's proposal is, in fact, neutral on the issue of numerical abstraction.

This selection of new approaches to the comparative study of religious ethics provides an accessible introduction to the most current research in the field. The essays in this book show that a variety of approaches to religious ethics are worth pursuing in our contemporary, profusely interconnected world. They also demonstrate that many sorts of analysis are shaped by comparison and comparative interests, even when they focus on a single topic or question, as long as they are informed by analogous studies (...) of other traditions, cultures, or religions. The volume exemplifies a thought-provoking, multidisciplinary engagement with global ethics today. (shrink)

Economics plays a key role in human rights issues as decision-makers weigh the incentives associated with choosing how to use scarce resources in the context of committing or escaping human rights violence. This textbook provides an introduction to the microeconomic analysis of human rights utilizing economics as a lens through which to examine social topics including capital punishment, violence against women, asylum seeking, terrorism, child abuse, genocide, and hate. Whether analyzing the decisions made in capital punishment cases, the causes and (...) consequences of genocide, or the impact of terrorist acts on domestic and international decision-making, the science of economics provides tools and a systematic method of analysis and policy recommendation. This key text presents a method for integrating the social sciences of economics and human rights to create new opportunities for the investigation of social issues. Within each chapter, readers gain a fundamental understanding of a specific human rights issue, the decision-makers and the decision-making process involved, and the benefits and costs leading to the decisions. Experts on each issue, drawn from a variety of fields, contribute to each chapter and present first-hand accounts and different perspectives on each issue. The detailed analyses and accounts provided also explore the potential incentives involved in the prevention and termination of human rights violations. Aiming to further economic inquiry and enhance interdisciplinary research, this textbook serves as a multi-purpose guide for a range of readers. Students, researchers, and educators, as well as those working in organizations supporting victims of human rights violations and policy-makers facing human rights challenges, will find this book informative and engaging.

This article suggests a way to circumvent some of the problems that follow from the lack of consensus on a definition of emotion (Izard, 2010; Kleinginna & Kleinginna, 1981) and emotion regulation (Cole, Martin, & Dennis, 2004) by adopting a conceptual framework based on discrete emotions theory and focusing on specific emotions. Discrete emotions theories assume that neural, affective, and cognitive processes differ across specific emotions and that each emotion has particular motivational and regulatory functions. Thus, efforts at regulation should (...) target the specific dysregulated emotions. The positive effects of emotion regulation are more likely to be optimized when they result from or lead to emotion utilization—the constructive use of the energy of emotion arousal. Effective processes for regulation differ for basic emotions and emotion schemas. This article identifies neural systems that facilitate emotion experiences and emotion regulation processes. It considers the implications of the developmental change from basic emotions to emotion schemas, and also briefly discusses the effects of interventions on changes in emotion knowledge, emotion regulation, and social and emotional competence.

In his article ‘Saints and Heroes’, Urmson argues that traditional moral theories allow at most for a threefold classification of actions in terms of their worth, and that they are therefore unsatisfactory. Since the conclusion of his argument has led to the widespread use of the term ‘acts of supererogation’, and since I do not believe that such acts exist, I propose to argue that the actions with which he is concerned not only can, but should, be contained within the (...) traditional classification.

The Metaphysics of Experience styles itself as "a Sherpa guide to Process and Reality, whose function is to assist the serious reader in grasping the meaning of the text and to prevent falls into misinterpretation." Although originally published in 1925, Process and Reality has perhaps even more relevance to the contemporary scene in physics, biology, psychology, and the social sciences than it had in the mid-twenties. Hence its internal difficulty, its quasi-inaccessibility, is all the more tragic, since, unlike most metaphysical (...) endeavors, it is capable of interpretating and unifying theories in the above sciences in terms of an organic world view, instead of selecting one theory as the paradigm and reducing all others to it. Because Alfred North Whitehead is so crucial to modern philosophy, The Metaphysics of Experience plays an important role in making Process and Reality accessible to a wider readership. (shrink)

Models of risk-taking as used in the social sciences may be improved by including concepts from life history theory, particularly environmental unpredictability and life expectancy. Community college students completed self-report questionnaires measuring these constructs along with several well-known correlates. The frequency of risk-taking was higher for those with higher future unpredictability beliefs and shorter lifespan estimates (as measured by the Future Lifespan Assessment developed for this study), and unpredictability beliefs remained significant after accounting for standard predictors, such as sex and (...) temperament. The results demonstrate the usefulness of applying concepts from life history theory to enhance our understanding of human behavior. (shrink)

This essay is a critical engagement with recent assessments of comparative religious ethics by John Kelsay and Jung Lee. Contra Kelsay's proposal to return to a neo-Weberian sociology of religious norm elaboration and justification, the authors argue that comparative religious ethics is and should be practiced as a field of study in active conversation with other fields that consider human flourishing, employing a variety of methods that have their roots in multiple disciplines. Cross-pollination from a variety of disciplines is a (...) strength of comparative ethics, which has enlivened recent and ongoing research on ethics, not a problem to be resolved by convergence on a single, distinctively comparative project. The authors also argue in response to Lee and Kelsay that while individual comparative studies of virtue and personal formation can be flawed in various ways, this line of research has been productive and at times very compelling. Moreover, attention to comparative virtue ethics shows how scholarship on some ethical topics necessitates drawing on a variety of perspectives and disciplinary backgrounds, a conclusion relevant to all work in religious ethics today.

This article reflects one scholar's attempt to locate herself within emerging ethical methodologies given a specific concern with cross-cultural women's moral praxis. The field of comparative ethics's debt to past debates over methodology is considered through a typology of three waves of methodological invention. The article goes on to describe a specific research focus on U.S. Catholic and Iranian Shii women that initiated a search for a distinct method. This method of comparative ethics, which focuses on the production of ethical (...) knowledge through the interaction of discursive logics of various moral agents, is described. The conclusion turns to how methodological invention can itself become a constructive project through the way it (1) locates the scholar in relation to her subject of study and (2) allows for isolation of tactics within specific moral discourses.

To introduce this set of essays on visual ethics, I address the conceptual and methodological contours, as well as difficult theoretical questions, that might emerge with a visual turn in religious ethics. In addition I situate the work represented in this focus issue within ongoing conversations about moral perception, culture as a topic of normative analysis, and the various roles of visual culture in the moral life.

A misleading and apparently addictive practice is now prevalent in discussions of philosophy in general, and moral philosophy in particular. This is the habit of dichotomizing. We are led to believe that we have to choose between reason and sentiment as the basis of morality, that facts and values are to be found on either side of an unbridgeable gulf, and so on. This practice is harmful because it leads philosophers to take sides in unnecessary conflicts which cannot be won (...) by either side, and thus prevents progress in the discussion of extremely important issues.

Moral disengagement is a process whereby the self-regulatory mechanisms that would otherwise sanction unethical conduct can be selectively disabled. The present research proposed that moral disengagement might be adopted in the endorsement of asylum seeker policies in Australia, and in order to test this, a scale was developed and was validated in two studies. Factor analysis demonstrated that a 2-factor, 16-item structure had the best fit, and the construct validity of the scale was supported. Results provide evidence for the use (...) of moral disengagement in the context of asylum seekers as a means of rationalizing conduct that may otherwise be sanctioned. (shrink)

In Philosophy 51, October 1976, 471–472, Professor Tom Regan takes ud to task for our attack on Kant's theory concerning the moral status of animals. The ground of Regan's criticism is that ‘… it is clear that Kant does not suppose, as… Broadie and Pybus erroneously assume that he does, that the concept of maltreating an animal, on the one hand, and, on the other, the concept of using an animal as a means, are the same or logically equivalent concepts’ (...) . Regan argues that Kant does not say that we should avoid treating animals as a means. Rather, he claims, Kant's view is that we have an indirect duty not to maltreat animals, since in maltreating them we treat, or run the risk of treating, as a mere means rationality in ourselves or in others.
