Generic statements express generalizations about categories and present a unique semantic profile that is distinct from quantified statements. This paper reports two studies examining the development of children's intuitions about the semantics of generics and how they differ from statements quantified by all, most, and some. Results reveal that, like adults, preschoolers recognize that generics have flexible truth conditions and are capable of representing a wide range of prevalence levels; and interpret novel generics as having near-universal prevalence implications. Results further (...) show that by age 4, children are beginning to differentiate the meaning of generics and quantified statements; however, even 7- to 11-year-olds are not adultlike in their intuitions about the meaning of most-quantified statements. Overall, these studies suggest that by preschool, children interpret generics in much the same way that adults do; however, mastery of the semantics of quantified statements follows a more protracted course.

Children and adults commonly produce more generic noun phrases (e.g., birds fly) about animals than artifacts. This may reflect differences in participants’ generic knowledge about specific animals/artifacts (e.g., dogs/chairs), or it may reflect a more general distinction. To test this, the current experiments asked adults and preschoolers to generate properties about novel animals and artifacts (Experiment 1: real animals/artifacts; Experiments 2 and 3: matched pairs of maximally similar, novel animals/artifacts). Data demonstrate that even without prior knowledge about these items, the (...) likelihood of producing a generic is significantly greater for animals than artifacts. These results leave open the question of whether this pattern is the product of experience and learned associations or instead a set of early-developing theories about animals and artifacts.

Generic statements (e.g., “Birds lay eggs”) express generalizations about categories. In this paper, we hypothesized that there is a paradoxical asymmetry at the core of generic meaning, such that these sentences have extremely strong implications but require little evidence to be judged true. Four experiments confirmed the hypothesized asymmetry: Participants interpreted novel generics such as “Lorches have purple feathers” as referring to nearly all lorches, but they judged the same novel generics to be true given a wide range of prevalence (...) levels (e.g., even when only 10% or 30% of lorches had purple feathers). A second hypothesis, also confirmed by the results, was that novel generic sentences about dangerous or distinctive properties would be more acceptable than generic sentences that were similar but did not have these connotations. In addition to clarifying important aspects of generics’ meaning, these findings are applicable to a range of real-world processes such as stereotyping and political discourse. (shrink)

This paper proposes that human expression of pain in the presence or absence of caregivers, and the detection of pain by observers, arises from evolved propensities. The function of pain is to demand attention and prioritise escape, recovery, and healing; where others can help achieve these goals, effective communication of pain is required. Evidence is reviewed of a distinct and specific facial expression of pain from infancy to old age, consistent across stimuli, and recognizable as pain by observers. Voluntary control (...) over amplitude is incomplete, and observers can better detect pain that the individual attempts to suppress rather than amplify or simulate. In many clinical and experimental settings, the facial expression of pain is incorporated with verbal and nonverbal vocal activity, posture, and movement in an overall category of pain behaviour. This is assumed by clinicians to be under operant control of social contingencies such as sympathy, caregiving, and practical help; thus, strong facial expression is presumed to constitute an attempt to manipulate these contingencies by amplification of the normal expression. Operant formulations support skepticism about the presence or extent of pain, judgments of malingering, and sometimes the withholding of caregiving and help. To the extent that pain expression is influenced by environmental contingencies, however, could equally plausibly constitute the release of suppression according to evolved contingent propensities that guide behaviour. Pain has been largely neglected in the evolutionary literature and the literature on expression of emotion, but an evolutionary account can generate improved assessment of pain and reactions to it.

This article argues that Augustine’s understanding of the internal dynamics of number, order, and weight as they pertain to corporeal creatures supplies the basis for an analogy which characterizes the process of the soul’s reformation. In other words, Augustine understands the soul’s simplicity in an analogous manner to the simplicity of corporeal creatures, and the simplicity of corporeal creatures is determined by the relations between number, order, and weight. This analogy shows that Augustine conceives of the soul as a composite (...) entity with different loves as its constituent parts. In the process of reformation, the soul acquires an ordered disposition as those loves become more like one another. By virtue of this ordered disposition, the soul also acquires a greater degree of integration or number because the likeness of weight among its constituent parts allows the soul to move as a unity toward God as its final end.

The experience of pain appears to be associated, from early infancy and across pain stimuli, with a consistent facial expression in humans. A social function is proposed for this: the communication of pain and the need for help to observers, to whom information about danger is of value, and who may provide help within a kin or cooperative relationship. Some commentators have asserted that the evidence is insufficient to account for the consistency of the face, as judged by technical means (...) or in the perceptions of observers, or that facial expression is epiphenomenal to a gross behavioural defensive response to pain. The major criticism is that it is unnecessary to invoke evolutionary mechanisms beyond the emergence of an unconditioned facial response to pain in neonates, subsequently shaped and maintained by instrumental and social reinforcement throughout life. These criticisms are addressed, acknowledging the need for further data to address some, and elaborating the areas in which evolutionary and operant mechanisms would predict different behavioural interactions, rather than acting synergistically. Several supportive commentaries propose extending evolutionarily-based hypotheses to sex differences, the complexities of others' responses within the social relationship, and the role of empathy. A number of commentators provided valuable suggestions for experimental paradigms or methodological issues. Overall, addressing these issues indicates the need for further conceptual development and for collection of data specifically in relation to these hypotheses. (shrink)

Studies of scientific practice demonstrate that the development of scientific models is an enactive and emergent process. Scientists make meaning through processes such as perspective taking, finding patterns, and following intuitions. In this paper, we focus on how a group of fourth grade learners and their teacher engaged in interpretation in ways that align with core ideas and practices in kinematics and computing. Cycles of measuring and modeling––including computer programming––helped to support classroom interactions that highlighted the interpretive nature of modeling (...) and participation in model construction as a knowledge-building process. We draw on literature from the history and philosophy of science in order to analyze the students’ interpretive actions as forms of epistemic and representational agency, constituting a construct we term disciplined interpretation. We demonstrate how students’ disciplined interpretative moves help to position them as owners of their own design decisions and their rights to interpret the phenomena they were modeling, data collected from those phenomena, and the scientific and computational models themselves. We present four extended episodes that characterize the nature of activity in the classroom and the development of students’ disciplined interpretations in terms of learning to recognize scientific patterns amid complex perceptual fields, and to represent them in ways that support sensemaking.

Plants belonging to the genus Salsola (Family: Chenopodiaceae) are common in the arid and semiarid regions of our planet with no less than 69 different Salsola species found in Namibia and the Republic of South Africa. This genus is used as a traditional medicine and aqueous extracts of Salsola have been used by Bushmen women as an oral contraceptive. Ingestion of the Namibian shrub Salsola tuberculatiformis Botsch. by pregnant Karakul sheep leads to prolonged gestation and fetal post‐maturity and, as a (...) result, the pelts of the new‐born karakul lambs are worthless. This initiated an investigation into the active agents in the plant, using the terminal enzyme in adrenal corticosteroidogenesis, cytochrome P450‐dependent 11β‐hydroxylase (P450c11), as a bioassay. Although the active fraction, S2, was extremely labile, partial structure determination suggested the presence of synephrine and a highly reactive aziridine. Therefore a more stable analogue, 2‐(4‐acetoxyphenyl)2‐chloro‐N‐methylethylammonium‐chloride (compound A), was synthesised, which, like the active plant extracts, inhibited adrenal steroidogenesis and acted as a contraceptive. In addition, compound A was stabilised by interaction with steroid‐binding globulins in plasma thus enhancing biological activity in vivo. These findings provided explanations for the complex biological effects of the shrub as well as a new insight into the mode of action of chemically labile plant products in vivo.

Neurological diseases, particularly in the context of aging, have serious impacts on quality of life and can negatively affect bone health. The brain-bone axis is critically important for skeletal metabolism, sensory innervation, and endocrine cross-talk between these organs. This review discusses current evidence for the cellular and molecular mechanisms by which various neurological disease categories, including autoimmune, developmental, dementia-related, movement, neuromuscular, stroke, trauma, and psychological, impart changes in bone homeostasis and mass, as well as fracture risk. Likewise, how bone may (...) affect neurological function is discussed. Gaining a better understanding of brain-bone interactions, particularly in patients with underlying neurological disorders, may lead to development of novel therapies and discovery of shared risk factors, as well as highlight the need for broad, whole-health clinical approaches toward treatment.

Globalization, technological advances, and changing employment structures have facilitated greater flexibility in how and where many Americans do their paid work. In response, a new work arrangement, coworking, has emerged in the United States. Coworking organizations bring together professionals from different companies to share a common workspace and build community. Despite the prevalence and potential benefits of coworking, little systematic research about coworking contexts exists, let alone research focused on gender inequality therein. Using 78 interviews and more than 700 hours (...) of observation across nine coworking spaces, we examine the organizational logics that shape gender dynamics, as well as intersecting racial and class dynamics, in coworking spaces. Building on Acker’s inequality regimes framework, we uncover organizational logic that either reduces or reproduces inequality for diverse groups of women in coworking contexts. We conclude by discussing important theoretical and empirical implications of these findings. (shrink)

Using a unique data set of causal usage drawn from research articles published between 2006–2008 in the American Journal of Sociology and American Sociological Review, this article offers an empirical assessment of causality in American sociology. Testing various aspects of what we consider the conventional wisdom on causality in the discipline, we find that “variablistic” or “covering law” models are not the dominant way of making causal claims, research methods affect but do not determine causal usage, and the use of (...) explicit causal language and the concept of “mechanisms” to make causal claims is limited. Instead, we find that metaphors and metaphoric reasoning are fundamental for causal claims-making in the discipline. On this basis, we define three dominant causal types used in sociology today, which we label the Probabilistic, Initiating and Conditioning types. We theorize this outcome as demonstrating the primary role that cognitive models play in providing inference-rich metaphors that allow sociologists to map causal relationships on to empirical processes.

Current uses of robots in classrooms are reviewed and used to characterise four scenarios: Robot as Classroom Teacher; Robot as Companion and Peer; Robot as Care-eliciting Companion; and Telepresence Robot Teacher. The main ethical concerns associated with robot teachers are identified as: privacy; attachment, deception, and loss of human contact; and control and accountability. These are discussed in terms of the four identified scenarios. It is argued that classroom robots are likely to impact children’s’ privacy, especially when they masquerade as (...) their friends and companions, when sensors are used to measure children’s responses, and when records are kept. Social robots designed to appear as if they understand and care for humans necessarily involve some deception, and could increase the risk of reduced human contact. Children could form attachments to robot companions, or robot teachers and this could have a deleterious effect on their social development. There are also concerns about the ability, and use of robots to control or make decisions about children’s behaviour in the classroom. It is concluded that there are good reasons not to welcome fully fledged robot teachers, and that robot companions should be given a cautious welcome at best. The limited circumstances in which robots could be used in the classroom to improve the human condition by offering otherwise unavailable educational experiences are discussed. (shrink)

A recent surge of research has begun to examine music participation and well-being; however, a particular challenge with this work concerns theorizing around the associated well-being benefits of musical participation. Thus, the current research used Self-Determination Theory to consider the potential associations between basic psychological needs (competence, relatedness, and autonomy), self-determined autonomous motivation, and the perceived benefits to well-being controlling for demographic variables and the musical activity parameters. A sample of 192 Australian residents (17-85, Mage = 36.95), who were currently (...) participating in a musical activity at the time, completed an online questionnaire. Results indicated that females were more likely to perceive benefits to their well-being; and that how important an individual considers music in their life was positively related to perceived well-being. Importantly, the analyses also revealed that the basic needs of competency and relatedness were related to overall perceived well-being as well as specifically social, cognitive, and esteem dimensions of well-being. Autonomous motivation demonstrated significant associations with both an overall well-being score as well as four of five specific well-being subscales measured. Collectively, the findings indicate that Self-Determination Theory offers a useful theoretical framework to understanding the relationship between musical participation and well-being. Further, the pattern of findings reiterates the positive associations between musical participation and one’s psychosocial well-being, with broad implications for people involved in the facilitation of musical activity.

Research on gender inequality within different-sex marriages shows that women do more unpaid labor than men, and that the perception of inequality influences perceptions of marital quality. Yet research on same-sex couples suggests the importance of considering how gender is relational. Past studies show that same-sex partners share unpaid labor more equally and perceive greater equity than do different-sex partners, and that lesbian, gay, and bisexual people are less gender conforming than heterosexuals. However, studies have not considered how gender conformity (...) might shape inequalities and marital quality within same- and different-sex unions. In this study, we analyze dyadic data from both spouses in same- and different-sex marriages to explore how sex of spouse and gender conformity influence perceptions of shared power within the relationship, which, in turn, influences marital quality. Results show that greater gender conformity is related to stronger perceptions of shared power in different-sex and male same-sex couples but not in female same-sex couples. Perceptions of shared power are positively associated with marital quality in all union types. Our findings suggest that maintaining hegemonic masculinity and power inequalities may be salient to marriages with men. In female same-sex couples, gender and its relation to power inequalities may carry less meaning. (shrink)

Evangelical scholars have recently offered criticisms of mind-body dualism from the disciplines of theology, philosophy, and neuroscience. We offer several arguments as to why these reasons for abandoning mind-body dualism fail. Additionally, we offer a positive thesis, a dualism that brings together the best aspects of the Cartesian view and the Thomistic view of human persons. The result is a substance dualism that treats the nature of embodiment quite seriously. This view explains why we, as souls, require a resurrected body (...) as well as accounting for the great good of our embodiment in general. A human person is at the same time wholly soul and yet fully bodily. (shrink)

Cognitive abilities cannot be measured directly. What we can measure is individual variation in task performance. In this paper, we first make the case for why we should be interested in mapping individual differences in task performance on to particular cognitive abilities: we suggest that it is crucial for examining the causes and consequences of variation both within and between species. As a case study, we examine whether multiple measures of inhibitory control for non-human animals do indeed produce correlated task (...) performance; however, no clear pattern emerges that would support the notion of a common cognitive ability underpinning individual differences in performance. We advocate a psychometric approach involving a three-step programme to make theoretical and empirical progress: first, we need tasks that reveal signature limits in performance. Second, we need to assess the reliability of individual differences in task performance. Third, multi-trait multi-method test batteries will be instrumental in validating cognitive abilities. Together, these steps will help us to establish what varies between individuals that could impact their fitness and ultimately shape the course of the evolution of animal minds. Finally, we propose executive functions, including working memory, inhibitory control and attentional shifting, as a sensible starting point for this endeavour. (shrink)

This study explores the relationship between decision-making styles and moral judgements to understand how maximizers and satisficers differ in their analysis of ethical dilemmas. It also explores the linkage between decision-making styles and the moral reasoning perspectives of absolutism and relativism, investigating if ethical ideologies play a mediating role in how maximizers and satisficers evaluate ethical situations. In order to test these relationships, data is collected from a sample of 187 upper level business students. Results indicate that maximizers are significantly (...) more likely than satisficers to judge ethically ambiguous actions as immoral. Underlying this effect, maximizers (vs. satisficers) have a more idealistic ethical ideology. (shrink)

Leibniz and Kant were the most important figures in German philosophy from the late 17th to the early 19th century. This volume examines the relationships between their philosophies, illuminating fundamental questions of metaphysics, epistemology, and philosophical theology, and assessing Kant's understanding of his philosophical predecessor.

This essay examines arguments offered in support of the Principle of Sufficient Reason (PSR) by Leibniz and his followers as well as Hume's critique of the PSR. It is shown that Leibniz has a defensible argument for the PSR, whereas the arguments of his self-proclaimed followers are weak. Thus, Hume's challenge is met by Leibniz, by Wolff and Baumgarten not so much.

Mental timing studies may be influenced by powerful cognitive illusions that can produce an asymmetry in their rate of progress relative to neuronal timing studies. Both types of timing research are also governed by a temporal asymmetry, expressed by the fact that the direction of causation must follow time's arrow. Here we refresh our earlier suggestion that the temporal asymmetry offers promise as a means of timing mental activities. We update our earlier analysis of Libet's data within this framework. Then (...) we consider the surprises which often occur on those rare occasions when neural timing experiments parallel mental timing work exactly. Together, these surprises and asymmetries prescribe a relentlessly meticulous and fully transparent exposition of timing methods, terms, and concepts which shuns plausible narratives, even when buttressed by rigorous formal models, unless guided by apposite empirical evidence.

This paper tries to show that there is an important virtue (with no generally recognized name) that could be called “accountability.” This virtue is a trait of a person who embraces being held accountable and consistently displays excellence in relations in which the person is held accountable. After describing the virtue in more detail, including its motivational profile, some core features of this virtue are described. Empirical implications and an agenda for future research are briefly discussed. Possible objections to the (...) virtue are considered and rebutted, and relations to other virtues, particularly the personal virtue of justice, are discussed. In conclusion, we suggest that though this virtue has not received the attention it deserves in contemporary society, it has been more clearly recognized in other cultures. Some of the reasons for the partial eclipse of the virtue are understandable and justifiable, but there are good reasons to think our society would be improved if we paid more attention to accountability from a virtue perspective.

The link between human nature and human flourishing is undeniable. "A healthy tree cannot bear bad fruit, nor can a diseased tree bear good fruit" (Matt. 7:18). The ontology of the human person will, therefore, ground the nature of human flourishing and thereby sanctification. Spiritual formation is the area of Christian theology that studies sanctification, the Spirit-guided process whereby disciples of Jesus are formed into the image of Jesus (Rom. 8:28-29; 2 Cor. 3:18; 2 Peter 3:18). Until the nineteenth century, (...) there was an overwhelming consensus among Christian thinkers that some form of mind-body (or soul-body) dualism is true of human beings. Recently, that consensus has eroded, and with it the availability of a shared body of knowledge about spiritual formation. Some Christian physicalists argue that dualism is incompatible with central elements of spiritual formation. Neuroscientist Warren Brown and psychologist Brad Strawn offer the only substantive account of spiritual formation from the view of Christian physicalism and its accompanying objections to dualism. It is on their arguments that this chapter focuses. We argue that Brown and Strawn fail to support their incompatibility thesis. Additionally, we argue that Christian physicalism stands in tension with important philosophical and theological foundations of Christian spiritual formation. In doing so we offer a specific form of dualism, the bodily soul view, and explain how this view illuminates the importance of embodiment, our neurological and social development, and hence the important physical aspects of Christian spiritual formation.

Sober (1992) has recently evaluated Brandon's (1982, 1990; see also 1985, 1988) use of Salmon's (1971) concept of screening-off in the philosophy of biology. He critiques three particular issues, each of which will be considered in this discussion.

Gottfried Wilhelm Leibniz (1646–1716) was one of the great thinkers of the seventeenth and eighteenth centuries and is known as the last “universal genius”. He made deep and important contributions to the fields of metaphysics, epistemology, logic, philosophy of religion, as well as mathematics, physics, geology, jurisprudence, and history. Even the eighteenth century French atheist and materialist Denis Diderot, whose views could not have stood in greater opposition to those of Leibniz, could not help being awed by his achievement, writing (...) in his Encyclopedia, “Perhaps never has a man read as much, studied as much, meditated more, and written more than Leibniz… What he has composed on the world, God, nature, and the soul is of the most sublime eloquence. If his ideas had been expressed with the flair of Plato, the philosopher of Leipzig would cede nothing to the philosopher of Athens.” (Vol. 9, p. 379) Indeed, Diderot's mood was almost despairing in a remark from another piece, which also has a great deal of truth in it: “When one compares the talents one has with those of a Leibniz, one is tempted to throw away one's books and go die quietly in the dark of some forgotten corner.” More than a century later, Gottlob Frege, who fortunately did not cast his books away in despair, expressed similar admiration, declaring that “in his writings, Leibniz threw out such a profusion of seeds of ideas that in this respect he is virtually in a class of his own.” (“Boole's logical Calculus and the Concept script” in Posthumous Writings , p. 9) The aim of this entry is primarily to introduce Leibniz's life and summarize and explicate his views in the realms of metaphysics, epistemology, philosophical theology, and natural philosophy.

This paper addresses D. C. Williams’s question, “How can Leibniz know that he is a member of the actual world and not merely a possible monad on the shelf of essence?” A variety of answers are considered. Ultimately, it is argued that no particular perception of a state of affairs in the world can warrant knowledge of one’s actuality, nor can the awareness of any property within oneself; rather, it is the nature of experience itself, with the flow of perceptions, (...) that guarantees our actuality. A consequence of this view is that no non-actual individuals can truly be said to experience their worlds, nor can they ask the question if they are actual or not. (shrink)

In the main article on Leibniz, it was claimed that Leibniz's philosophy can be seen as a reaction to the Cartesian theory of corporeal substance and the necessitarianism of Spinoza and Hobbes. This entry will address this second aspect of his philosophy. In the course of his writings, Leibniz developed an approach to questions of modality—necessity, possibility, contingency—that not only served an important function within his general metaphysics, epistemology, and philosophical theology but also has continuing interest today. Indeed, it has..

In a short piece written most likely in the 1690s and given the title by Loemker of “On Wisdom,” Leibniz says the following: “...we see that happiness, pleasure, love, perfection, being, power, freedom, harmony, order, and beauty are all tied to each other, a truth which is rightly perceived by few.”1 Why is this? That is, why or how are these concepts tied to each other? And, why have so few understood this relation? Historians of philosophy are familiar with the (...) fact that both Spinoza and Leibniz place strong emphasis on the notion of power in giving their accounts of the human passions. But, while many scholars have explicated the relation between power and the passions (especially in Spinoza’s philosophy), there has been considerably less attention given to the nature of perfection and its relation to both power and the passions.2 Consider the following passages from Spinoza and Leibniz in which these two thinkers seem to bring together the issue of perfection and passion. In Ethics IIIp11s, Spinoza says the following: We see, then, that the Mind can undergo great changes, and pass now to a greater, now to a lesser perfection. These passions, indeed, explain to us the affects of Joy and Sadness. By Joy, therefore, I shall understand in what follows that passion by which the Mind passes to a greater perfection. And by Sadness, that passion by which it passes to a lesser perfection. The affect of Joy which is related to the Mind and Body at once I call Pleasure or Cheerfulness, and that of Sadness, Pain or Melancholy.3 And, in the Monadology §49, Leibniz says this: “The creature is said to act externally insofar as it is perfect, and to be acted upon [patir] by another, insofar as it is imperfect.”4 In other words, for Spinoza, the primitive passions of joy and sadness are cases in which a being’s perfection is increasing or decreasing, while, for Leibniz, any passion, it would..

That Leibniz finds the philosophy of Spinoza horrifyingly wrong is obvious to anyone who reads Leibniz’s work; that Leibniz finds Spinozism so seductive that his own system is in danger of collapsing into it is less obvious but, I believe, equally true. The difference here is not so much between an exoteric and an esoteric philosophy suggested by Russell2 but between a thorough-going rationalism on the part of Spinoza and Leibniz’s “mitigated rationalism” – mitigated by the exigencies of his orthodox (...) Christianity. In other words, it is Leibniz’s traditional view of the nature of God and his creatures that leads him to abhor Spinoza’s vision, while his own commitment to a number of principles and ideas pushes him to rationalism. And if Kant is right that the mind naturally desires a system, then Leibniz ought to see the Spinozistic consequences of many of his philosophical principles. Of course, there is nothing new in saying that the God of Spinoza and the God of Leibniz are fundamentally different, but I believe that if we focus on Leibniz’s critique of Spinoza’s account of the nature of God and a constellation of related concepts, we can come to a deeper understanding of the thought of both philosophers.
