Using a cross-modal semantic priming paradigm, both experiments of the present study investigated the link between the mental representations of iconic gestures and words. Two groups of the participants performed a primed lexical decision task where they had to discriminate between visually presented words and nonwords (e.g., flirp). Word targets (e.g., bird) were preceded by video clips depicting either semantically related (e.g., pair of hands flapping) or semantically unrelated (e.g., drawing a square with both hands) gestures. The duration of gestures (...) was on average 3,500 ms in Experiment 1 but only 1,000 ms in Experiment 2. Significant priming effects were observed in both experiments, with faster response latencies for related gesture–word pairs than unrelated pairs. These results are consistent with the idea of interactions between the gestural and lexical representational systems, such that mere exposure to iconic gestures facilitates the recognition of semantically related words.

This paper explores the idea that moral thought/reasoning and moral actions are actually two separate phenomena that have little relationship to each other. The idea that moral thinking does or can control moral action creates a difficult dualism between our knowledge about morality and our everyday actions. These differences run parallel to the distinction between social capital and cultural capital—where social capital is based on cooperation and trust and leads to purposeful solutions to real time social problems and cultural capital (...) serves as a shorthand sign that certain individuals should be recognized as accepted members of an ongoing community. Social capital and cultural capital, like moral action and moral thought, are related and sometimes even dependent on each other, but they are different phenomena sometimes working towards different purposes. We suggest that moral action is actually a form and an originating source of social capital and moral thought is an important form of cultural capital in many social groups. The differences between moral action and moral thought can lead to social tensions—including which is more valuable and how each should be approached in terms of education. John Dewey suggested that morality is tied to active engagement in the solving of a community's problems and should be integrated into the everyday activities of the classroom. Those who view morality through more of a cultural capital lens often times see morality as a stable set of social values—an important resource that needs to be transmitted between generations.

This paper explores the issue of democracy and the role of the democratic classroom in the development of society in general, and the way in which educators understand and deal with diversity in particular. The first part of the paper explores different meanings of democracy and how they can be manifested in the classroom. We argue that the idea of a ‘democratic classroom’ is far too broad a category; democracy is defined in action and can have realist or pragmatic characteristics, (...) elitist or pluralist roots. The realist form of social education was championed by political scientist Charles Merriam, while a social educative process more dependent on pragmatic problem solving was pursued by educational philosopher John Dewey and those who followed in his theoretical wake. The history of democracy in the United States, and the battles of how to import different meanings of democracy into the classroom over the course of the 20th century is explored, suggesting that the educational establishment has a tendency to adopt more realist/elitist forms of civic education. We present five ‘democratic’ classrooms with different characteristics to illustrate the different characteristics social education can exhibit. In the second part of the paper we discuss the relationship between different types of democratic classrooms and issues of race/ethnicity/culture. (shrink)
This commentary explores the reproductive strategies and attachment patterns among homeless youths. Del Giudice's integrated evolutionary model is applied to a homeless youth population that must function in ecological settings of constant high risk and stress. Different reproductive needs result in different patterns of high-risk behaviors. Intervention considering the sex differences, life history, and early caregiver–child relationships is suggested.
In this commentary we explore Knobe's ideas of moral judgments leading to moral intuitions in the context of the moral thought and moral action debate. We suggest that Knobe's primary moral judgment and the setting of a continuum with a default point is in essence a form of cultural capital, different from moral action, which is more akin to social capital.
The meshed control theory assumes that cognitive control and automatic processes work together in the natural attention of experts for superior performance. However, the methods adopted by previous studies limit their capacity to provide in-depth information on the neuromotor processes. This experiment tested the theory with an alternative approach. Twelve skilled golfers were recruited to perform a putting task under three conditions: normal condition, with no focus instruction, external focus of attention condition, and internal focus of attention condition. Four blocks (...) of 10 putts each were performed under each condition. The putting success rate and accuracy were measured and electroencephalographies were recorded. The behavioral results showed that the NC produced a higher putting success rate and accuracy than the EC and IC. The EEG data showed that the skilled golfers’ attentional processes in the NC initially resembled those in the EC and then moved toward those in the IC just before putting. This indicates a switch from more automatic processes to cognitive control processes while preparing to putt. The findings offer support for the meshed control theory and indicate the dynamic nature of neuromotor processes for the superior performance of athletes in challenging situations. (shrink)
BackgroundAmidst expanding roles in education and policy making, questions have been raised about the ability of Clinical Ethics Committees s to carry out effective ethics consultations. However recent reviews of CECs suggest that there is no uniformity to CECons and no effective means of assessing the quality of CECons. To address this gap a systematic scoping review of prevailing tools used to assess CECons was performed to foreground and guide the design of a tool to evaluate the quality of CECons.MethodsGuided (...) by Levac et al’s methodological framework for conducting scoping reviews, the research team performed independent literature reviews of accounts of assessments of CECons published in six databases. The included articles were independently analyzed using content and thematic analysis to enhance the validity of the findings.ResultsNine thousand sixty-six abstracts were identified, 617 full-text articles were reviewed, 104 articles were analyzed and four themes were identified – the purpose of the CECons evaluation, the various domains assessed, the methods of assessment used and the long-term impact of these evaluations.ConclusionThis review found prevailing assessments of CECons to be piecemeal due to variable goals, contextual factors and practical limitations. The diversity in domains assessed and tools used foregrounds the lack of minimum standards upheld to ensure baseline efficacy.To advance a contextually appropriate, culturally sensitive, program specific assessment tool to assess CECons, clear structural and competency guidelines must be established in the curation of CECons programs, to evaluate their true efficacy and maintain clinical, legal and ethical standards.

While univariate functional magnetic resonance imaging data analysis methods have been utilized successfully to map brain areas associated with cognitive and emotional functions during viewing of naturalistic stimuli such as movies, multivariate methods might provide the means to study how brain structures act in concert as networks during free viewing of movie clips. Here, to achieve this, we generalized the partial least squares analysis, based on correlations between voxels, experimental conditions, and behavioral measures, to identify large-scale neuronal networks activated during (...) the first time and repeated watching of three ∼5-min comedy clips. We identified networks that were similarly activated across subjects during free viewing of the movies, including the ones associated with self-rated experienced humorousness that were composed of the frontal, parietal, and temporal areas acting in concert. In conclusion, the PLS method seems to be well suited for the joint analysis of multi-subject neuroimaging and behavioral data to quantify a functionally relevant brain network activity without the need for explicit temporal models.

İlahî vahyin son halkası olan Kur’ân, şirk, küfür, nifak ve zulmün her türlüsünden insanlığı kurtarmak için gönderilmiştir. Kur’ân, kendini yeni bir medeniyyet tasavvuru olarak insanlığa takdim etmiştir. Bunun için kendisine inananların, onu okuma, anlama ve hayatlarına rehber olmasını istemektedir. Müslümanlar, Kur’ân’ı sadece telaffuz ederek onun istediği bu rehberliği yerine getirmiş olamazlar. Müslümanlar, hem ellerinde bulunan Kur’ân âyetlerinden ve hem de çevrelerinde yer alan ve her gün yüz yüze kaldıkları kâinattaki âyetlerden gereğince istifade etmek zorundadırlar. Kur’ân, kendisini kabul edenlerin inanç, ibadet, (...) kişilik, kimlik, düşünce yapısı ve davranışlarının tevhide göre şekillenmesini ister. Şâyet Kur’ân’a inananların bu özelliklerinde bir değişim meydana gelmiyorsa, burada sorgulanması gereken çok ciddi problemler var demektir. Hiç kuşkusuz bugünkü Kur’ân eğitimi yöntemiyle, Kur’ân’ın istediği medeniyet seviyesini ve mü’min kişilikleri oluşturmamız mümkün değildir. Bu makalede hem Kur’ân’la olan ilişkilerimizin nasıl olması gerektiğini hem de toplumsal anlamda değişim ve dönüşümün esaslarını belirlemeye çalıştık. (shrink)
This book contains new essays in honor of Melvin J. Lerner, a pioneer in the psychological study of justice. The contributors to this volume are internationally renowned scholars from psychology, business, and law. They examine the role of justice motivation in a wide variety of contexts, including workplace violence, affirmative action programs, helping or harming innocent victims and how people react to their own fate. Contributors explore fundamental issues such as whether people's interest in justice is motivated by self-interest (...) or a genuine concern for the welfare of others, when and why people feel a need to punish transgressors, how a concern for justice emerges during the development of societies and individuals, and the relation of justice motivation to moral motivation. How an understanding of justice motivation can contribute to the amelioration of major social problems is also examined. (shrink)
An ad hominem fallacy is committed when an individual employs an irrelevant personal attack against an opponent instead of addressing that opponent’s argument. Many discussions of such fallacies discuss judgments of relevance about such personal attacks, and consider how we might distinguish those that are relevant from those that are not. This paper will argue that the literature on bias and testimony can helpfully contribute to that analysis. This will highlight ways in which biases, particularly unconscious biases, can make ad (...) hominem fallacies seem effective, even when the irrelevance is recognized. (shrink)
Open Access: This paper will connect literature on epistemic injustice with literature on victims and perpetrators, to argue that in addition to considering the credibility deficit suffered by many victims, we should also consider the credibility excess accorded to many perpetrators. Epistemic injustice, as discussed by Miranda Fricker, considers ways in which someone might be wronged in their capacity as a knower. Testimonial injustice occurs when there is a credibility deficit as a result of identity-prejudicial stereotypes. However, criticisms of Fricker (...) have pointed out that credibility is part of a more complex system that includes both deficits and excesses. I will use these points to argue that we should look closer at sources of credibility excess in cases of sexual assault. This means that in addition to considering sources of victim blaming by looking at ways in which “ideal” victims are constructed, we also need to consider ways in which “ideal” perpetrators are constructed.

Feminist epistemologies consider ways in which gender influences knowledge. In this article, I want to consider a particular kind of feminist empiricism that has been called feminist radical empiricism. I am particularly interested in this view's treatment of values as empirical, and consequently up for revision on the basis of empirical evidence. Proponents of this view cite the fact that it allows us to talk about certain things such as racial and gender equality as objective facts: not just whether we (...) have achieved said equality in our society, but whether we are, in fact, all equal. I will raise the concern that the way in which they model the role of values in epistemology may be a problematic idealization of the open-mindedness of human agents. In some cases, resistance to value-change cannot be diagnosed as a failure to respond adequately to evidence. If so, the strategy of empirically testing our values that some feminist radical empiricists suggest may not be as useful a tool for social change as they think. (shrink)
There are two general questions which many views in the philosophy of mathematics can be seen as addressing: what are mathematical objects, and how do we have knowledge of them? Naturally, the answers given to these questions are linked, since whatever account we give of how we have knowledge of mathematical objects surely has to take into account what sorts of things we claim they are; conversely, whatever account we give of the nature of mathematical objects must be accompanied by (...) a corresponding account of how it is that we acquire knowledge of those objects. The connection between these problems results in what is often called "Benacerraf's Problem", which is a dilemma that many philosophical views about mathematical objects face. It will be my goal here to present a view, attributed to Richard Dedekind, which approaches the initial questions in a different way than many other philosophical views do, and in doing so, avoids the dilemma given by Benacerraf's problem.

Many criticisms of epistemic logic have centered around its use of devices such as idealized knowers with logical omniscience and perfect self-knowledge. One possible response to such criticisms is to say that these idealizations are normative devices, and that epistemic logic tells us how agents ought to behave. This paper will take a different approach, treating epistemic logic as descriptive, and drawing the analogy between its formal models and idealized scientific models on that basis. Treating it as descriptive matches the (...) way in which some philosophers, including one of its founders, Jaako Hintikka, have thought about epistemic logic early in its history. Further, the analogy between the two fields will give us a way to defuse criticisms that see epistemic logic as unrealistic. For example, criticizing models of epistemic logic in which agents know all propositional tautologies as being unrealistic would be like criticizing frictionless planes in physics for being unrealistic. Each one would certainly be an unsuitable model for studying some kinds of phenomena, but is entirely appropriate for others. After outlining the analogy between epistemic and scientific models, we will discuss some ways in which idealizations are used by different research programs in epistemic logic. (shrink)
The logical empiricists often appear as a foil for feminist theories. Their emphasis on the individualistic nature of knowledge and on the value-neutrality of science seems directly opposed to most feminist concerns. However, several recent works have highlighted aspects of Carnap's views that make him seem like much less of a straightforwardly positivist thinker. Certain of these aspects lend themselves to feminist concerns much more than the stereotypical picture would imply.
Dedekind's major work on the foundations of arithmetic employs several techniques that have left him open to charges of psychologism, and through this, to worries about the objectivity of the natural-number concept he defines. While I accept that Dedekind takes the foundation for arithmetic to lie in certain mental powers, I will also argue that, given an appropriate philosophical background, this need not make numbers into subjective mental objects. Even though Dedekind himself did not provide that background, one can nevertheless (...) be found in the work of the neo-Kantian Ernst Cassirer on mathematical concept formation. (shrink)
_The Undiscovered Dewey_ explores the profound influence of evolution and its corresponding ideas of contingency and uncertainty on John Dewey's philosophy of action, particularly its argument that inquiry proceeds from the uncertainty of human activity. Dewey separated the meaningfulness of inquiry from a larger metaphysical story concerning the certainty of human progress. He then connected this thread to the way in which our reflective capacities aid us in improving our lives. Dewey therefore launched a new understanding of the modern self (...) that encouraged intervention in social and natural environments but which nonetheless demanded courage and humility because of the intimate relationship between action and uncertainty. Melvin L. Rogers explicitly connects Dewey's theory of inquiry to his religious, moral, and political philosophy. He argues that, contrary to common belief, Dewey sought a place for religious commitment within a democratic society sensitive to modern pluralism. Against those who regard Dewey as indifferent to moral conflict, Rogers points to Dewey's appreciation for the incommensurability of our ethical commitments. His deep respect for modern pluralism, argues Rogers, led Dewey to articulate a negotiation between experts and the public so that power did not lapse into domination. Exhibiting an abiding faith in the reflective and contestable character of inquiry, Dewey strongly engaged with the complexity of our religious, moral, and political lives. (shrink)
It is a commonly held view that Dedekind's construction of the real numbers is impredicative. This naturally raises the question of whether this impredicativity is justified by some kind of Platonism about sets. But when we look more closely at Dedekind's philosophical views, his ontology does not look Platonist at all. So how is his construction justified? There are two aspects of the solution: one is to look more closely at his methodological views, and in particular, the places in which (...) predicativity restrictions ought to be applied; another is to take seriously his remarks about the reals as things created by the cuts, instead of considering them to be the cuts themselves. This can lead us to make finer-grained distinctions about the extent to which impredicative definitions are problematic, since we find that Dedekind's use of impredicative definitions in analysis can be justified by his philosophical views.

Bilattices, due to M. Ginsberg, are a family of truth value spaces that allow elegantly for missing or conflicting information. The simplest example is Belnap’s four-valued logic, based on classical two-valued logic. Among other examples are those based on finite many-valued logics, and on probabilistic valued logic. A fixed point semantics is developed for logic programming, allowing any bilattice as the space of truth values. The mathematics is little more complex than in the classical two-valued setting, but the result provides (...) a natural semantics for distributed logic programs, including those involving confidence factors. The classical two-valued and the Kripke/Kleene three-valued semantics become special cases, since the logics involved are natural sublogics of Belnap’s logic, the logic given by the simplest bilattice.

Mahadevan proposes that we are at the cusp of imagination science, one of whose primary concerns will be the design of imagination machines. Programs have been written that are capable of generating jokes, producing line-drawings that have been exhibited at such galleries as the Tate, composing music in several styles reminiscent of such greats as Vivaldi and Mozart, proving geometry theorems, and inducing quantitative laws from empirical data. In recent years, Dartmouth has been hosting Turing Tests in creativity in three (...) categories: short stories, sonnets, and dance music DJ sets. In this post, I will provide a brief and non-exhaustive survey of some plausible responses to these imagination machines and the related prospects for our understanding of the imagination. (shrink)
A new semantics is presented for the logic of proofs (LP), [1, 2], based on the intuition that it is a logic of explicit knowledge. This semantics is used to give new proofs of several basic results concerning LP. In particular, the realization of S4 into LP is established in a way that carefully examines and explicates the role of the + operator. Finally connections are made with the conventional approach, via soundness and completeness results.
David Walker’s famous 1829 Appeal to the Colored Citizens of the World expresses a puzzle at the very outset. What are we to make of the use of “Citizens” in the title given the denial of political rights to African Americans? This essay argues that the pamphlet relies on the cultural and linguistic norms associated with the term appeal in order to call into existence the political standing of black folks. Walker’s use of citizen does not need to rely on (...) a recognitive legal relationship precisely because it is the practice of judging that illuminates one’s political, indeed, citizenly standing. Properly understood, the Appeal aspires to transform blacks and whites, and when it informs the prophetic dimension of the text, it tilts the entire pamphlet in a democratic direction. This is the political power of the pamphlet; it exemplifies the call-and-response logic of democratic self-governance. (shrink)
Two families of many-valued modal logics are investigated. Semantically, one family is characterized using Kripke models that allow formulas to take values in a finite many-valued logic, at each possible world. The second family generalizes this to allow the accessibility relation between worlds also to be many-valued. Gentzen sequent calculi are given for both versions, and soundness and completeness are established.
Kleene’s strong three-valued logic extends naturally to a four-valued logic proposed by Belnap. We introduce a guard connective into Belnap’s logic and consider a few of its properties. Then we show that by using it four-valued analogs of Kleene’s weak three-valued logic, and the asymmetric logic of Lisp are also available. We propose an extension of these ideas to the family of distributive bilattices. Finally we show that for bilinear bilattices the extensions do not produce any new equivalences.
Radical scepticism contends that our knowledge of the external world is impossible. Particularly, radical scepticism can be motivated by the closure principle. Several commentators have noted that a straightforward way to respond to such arguments is via externalist strategies, e.g., Goldman, Greco, Bergmann. However, these externalist strategies are not effective against a slightly weaker form of the argument, a closure principle for rationally grounded knowledge, closureRK.\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${closure}_{RK.}$$\end{document} The sceptical argument, framed around the (...) closureRK\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\hbox {closure}_{\mathrm{RK}}$$\end{document} principle, targets rationally grounded knowledge. Although externalist strategies are ineffective against this form of argument, its conclusion can nonetheless be resisted by combining, in a novel way, the resources of Wittgenstein and Davidson.

In a forthcoming paper, Walter Carnielli and Abilio Rodrigues propose a Basic Logic of Evidence whose natural deduction rules are thought of as preserving evidence instead of truth. BLE turns out to be equivalent to Nelson’s paraconsistent logic N4, resulting from adding strong negation to Intuitionistic logic without Intuitionistic negation. The Carnielli/Rodrigues understanding of evidence is informal. Here we provide a formal alternative, using justification logic. First we introduce a modal logic, KX4, in which \ can be read as asserting (...) there is implicit evidence for X, where we understand evidence to permit contradictions. We show BLE embeds into KX4 in the same way that Intuitionistic logic embeds into S4. Then we formulate a new justification logic, JX4, in which the implicit evidence motivating KX4 is made explicit. KX4 embeds into JX4 via a realization theorem. Thus BLE has both implicit and explicit possibly contradictory evidence interpretations in a formal sense. (shrink)
