Many theories about human number representation stress the importance of a central semantic representation that includes the magnitude information of small integer numbers, and that is conceived as an abstract, compressed number line. However, thus far there has been little or no direct evidence that units and teens are represented on the same number line. In two masked priming experiments, we show that single-digit and two-digit Arabic numerals are equally well primed by an Arabic numeral with the same number of (...) digits as by an equally distant Arabic numeral with a different number of digits (e.g. the priming effect of 7 on the target 9 is the same as the priming effect of 11 on the target 9). The finding was obtained both with a number naming task and with a parity judgement task. This is in line with the hypothesis that units and teens are part of a continuous number line. (shrink)

Cohen Kadosh & Walsh (CK&W) argue that numerical representation is primarily non-abstract. However, in their target article they failed to consider recent behavioral priming experiments. These priming experiments provide evidence for an abstract numerical representation under automatic conditions.

Clarke and Beck discuss in their sections on congruency and confounds literature that has challenged the claim that the approximate number system represents numerical content. We argue that the propositions put forward by these studies aren't that far from the indirect model of number perception suggested by C&B.

6 and 14 recently proposed taxonomies that distinguish between four processing states, based on bottom-up stimulus strength and top-down attentional amplification. The aim of the present study was to empirically test these processing states using the priming paradigm. Our results showed that attention and stimulus strength significantly modulated priming effects: either receiving top-down attention or possessing sufficient bottom-up strength was a prerequisite for a stimulus to elicit priming. When both top-down attention and sufficient bottom-up strength were present, the priming effect (...) was boosted. The origins of the observed priming effects also varied between different processing states. We can conclude that our empirical study using the priming paradigm confirmed the presence of four processing states, which displayed a differential pattern of response priming effects and differential origins of the response priming effects.

Math anxiety results in a drop in performance on various math-related tasks, including the symbolic number ordering task in which participants decide whether a triplet of digits is presented in order (e.g. 3-5-7) or not (e.g. 3-7-5). We investigated whether the strategy repertoire and reaction times during a symbolic ordering task were affected by math anxiety. In study 1, participants performed an untimed symbolic number ordering task and indicated the strategy they used on a trial-by-trial basis. The use of the (...) memory retrieval strategy, based on the immediate recognition of the triplet, decreased with high math anxiety, but disappeared when controlling for general anxiety. In the study 2, participants completed a timed version of the number order task. High math-anxious participants used the decomposition strategy (e.g. 5 is larger than 3 and 7 is larger than 5 to decide whether 3-5-7 is in the correct order) more often, and were slower in responding when both memory- and other decomposition strategies were used. Altogether, both studies demonstrate that high-math anxious participants are not only slower to decide whether a number triplet is in the correct order, but also rely more on procedural strategies.

Although the principle of informed consent is well established and its importance widely acknowledged, it has met with criticism for decades. Doubts have been raised for a number of different reasons. In particular, empirical data show that people regularly fail to reproduce the information provided to them. Many critics agree, therefore, that the received concept of informed consent is no more than a myth. Strategies to overcome this problem often rest on a flawed concept of informed consent. In this paper, (...) it is suggested that informed consent is a communicative act between two persons. The challenge is to elucidate the norms and constraints for successfully performing such a communicative act. The view developed here has major consequences with regard to the standards for information disclosure as well as for the general scope of informed consent. (shrink)

Some common explanations of issue polarization and echo chambers rely on social or cognitive mechanisms of exclusion. Accordingly, suggested interventions like “be more open-minded” target these mechanisms: avoid epistemic bubbles and don’t discount contrary information. Contrary to such explanations, we show how a much weaker mechanism—the preference for belief—can produce issue polarization in epistemic communities with little to no mechanisms of exclusion. We present a network model that demonstrates how a dynamic interaction between the preference for belief and common structures (...) of epistemic communities can turn very small unequal distributions of initial beliefs into full-blown polarization. This points to a different class of explanations, one that emphasizes the importance of the initial spread of information. We also show how our model complements extant explanations by including a version of biased assimilation and motivated reasoning—cognitive mechanisms of exclusion. We find that mechanisms of exclusion can exacerbate issue polarization, but may not be the ultimate root of it. Hence, the recommended interventions suggested by extant literature is expected to be limited and the problem of issue polarization to be even more intractable. (shrink)

In spite of the remarkable progress made in the burgeoning field of social neuroscience, the neural mechanisms that underlie social encounters are only beginning to be studied and could —paradoxically— be seen as representing the ‘dark matter’ of social neuroscience. Recent conceptual and empirical developments consistently indicate the need for investigations, which allow the study of real-time social encounters in a truly interactive manner. This suggestion is based on the premise that social cognition is fundamentally different when we are in (...) interaction with others rather than merely observing them. In this article, we outline the theoretical conception of a second-person approach to other minds and review evidence from neuroimaging, psychophysiological studies and related fields to argue for the development of a second-person neuroscience, which will help neuroscience to really go social; this may also be relevant for our understanding of psychiatric disorders construed as disorders of social cognition.

Ethicists differ considerably in their reasons for using empirical data. This paper presents a brief overview of four traditional approaches to the use of empirical data: “the prescriptive applied ethicists,” “the theorists,” “the critical applied ethicists,” and “the particularists.” The main aim of this paper is to introduce a fifth approach of more recent date (i.e. “integrated empirical ethics”) and to offer some methodological directives for research in integrated empirical ethics. All five approaches are presented in a table for heuristic (...) purposes. The table consists of eight columns: “view on distinction descriptive-prescriptive sciences,” “location of moral authority,” “central goal(s),” “types of normativity,” “use of empirical data,” “method,” “interaction empirical data and moral theory,” and “cooperation with descriptive sciences.” Ethicists can use the table in order to identify their own approach. Reflection on these issues prior to starting research in empirical ethics should lead to harmonization of the different scientific disciplines and effective planning of the final research design. Integrated empirical ethics (IEE) refers to studies in which ethicists and descriptive scientists cooperate together continuously and intensively. Both disciplines try to integrate moral theory and empirical data in order to reach a normative conclusion with respect to a specific social practice. IEE is not wholly prescriptive or wholly descriptive since IEE assumes an interdepence between facts and values and between the empirical and the normative. The paper ends with three suggestions for consideration on some of the future challenges of integrated empirical ethics. (shrink)

Vijf bijdragen over de visie van de Duitse filosoof (1889-1976) op de verhouding van het dier tot de wereld.

How do Dutch people let each other know that they disagree? What do they say when they want to resolve their difference of opinion by way of an argumentative discussion? In what way do they convey that they are convinced by each other’s argumentation? How do they criticize each other’s argumentative moves? Which words and expressions do they use in these endeavors? By answering these questions this short essay provides a brief inventory of the language of argumentation in Dutch.

The study of argumentation is prospering. After its brilliant start in Antiquity, highlighted in the classical works of Aristotle, after an alternation of ups and downs during the following millennia, in the post-Renaissance period its gradual decline set in. Revitalization took place only after Toulmin and Perelman published in the same year their landmark works The Uses of Argument and La nouvelle rhétorique. The model of argumentation presented by Toulmin and Perelman’s inventory of argumentation techniques inspired a great many scholars (...) in various ways to take up the study of argumentation in a serious manner. Nowadays there are well-established logical approaches to argumentation, but also social and socio-psychological, linguistic, juridical and other approaches. In most of these approaches traces can be found of the influence of the classical and neo-classical argumentation theories just mentioned. (shrink)

The method of reflective equilibrium is typically characterized as a process of two kinds of adjustments: hold fixed one’s current set of commitments/intuitions and adjust rules/principles to account for them, then hold fixed those rules while making adjustments to one’s set of commitments. Repeat until no further adjustments are required. Such characterizations ignore the role of precedent, i.e., information about the commitments and rules of others and how those might serve as guides in one’s own process of deliberation. In this (...) paper we develop a model that narrows in on a local part of a reflective equilibrium process in which a group of peer agents start with identical lists of commitments and work towards finding the rule that captures that set. If successful, we say they reach rest stop interpersonal convergence. The trouble is that, without precedent, reaching this convergence rests on implausible deterministic assumptions. We analyze how far the inclusion of a kind of soft precedent goes towards aiding the group in reaching said convergence when those assumptions are relaxed. (shrink)

If one compares the development of modern medical ethics in Germany with those in the Netherlands, what stands out are the cultural and intellectual differences between the two countries. Dealing with the problems involved in limiting medical treatment, the authors show the differing and the common standards and values on which the discussion of this is based in both countries. Three examples, active termination of life, the do-not-resuscitate order and pain management, which are examined from an historical, legal, philosophical and (...) ethical perspective, put this in concrete terms. The authors belong to different generations as well as different political and philosophical camps. Vergleicht man die Entwicklung der modernen Medizinethik in Deutschland mit jener in den Niederlanden, fallen die kulturellen und intellektuellen Unterschiede zwischen beiden Landern deutlich auf. Anhand der Problematik der Begrenzung medizinischen Handelns zeigen die Autoren die verschiedenen bzw. gemeinsamen Normen und Werte, die der Diskussion daruber in beiden Landern zugrunde liegen. Drei Beispiele, die aktive Lebensbeendigung, die Nicht-Reanimierung und die Schmerzbekampfung, die aus historischem, juristischem, philosophischem und ethischem Blickwinkel betrachtet werden, konkretisieren die Darstellung. Die Autoren gehoren unterschiedlichen Generationen, politischen und lebensanschaulichen Lagern an. (shrink)

Opinions are rarely binary; they can be held with different degrees of conviction, and this expanded attitude spectrum can affect the influence one opinion has on others. Our goal is to understand how different aspects of influence lead to recognizable spatio-temporal patterns of opinions and their strengths. To do this, we introduce a stochastic spatial agent-based model of opinion dynamics that includes a spectrum of opinion strengths and various possible rules for how the opinion strength of one individual affects the (...) influence that this individual has on others. Through simulations, we find that even a small amount of amplification of opinion strength through interaction with like-minded neighbors can tip the scales in favor of polarization and deadlock.

In this article, I present two conceptual problems for Craver's mutual manipulability account of constitutive relevance in mechanisms. First, constitutive relevance threatens to imply causal relevance despite Craver (and Bechtel)'s claim that they are strictly distinct. Second, if (as is intuitively appealing) parthood is defined in terms of spatio-temporal inclusion, then the mutual manipulability account is prone to counterexamples, as I show by a case of endosymbiosis. I also present a methodological problem (a case of experimental underdetermination) and formulate two (...) partial, but fallible solutions based on the notions of parthood and synchronicity.

This article offers a general discussion of the concept of false hope. Its ultimate aim is to clarify the meaning and the relevance of that concept for medicine and medical research. In the first part, the concept of hope is discussed. I argue that hope is more than a combination of a desire and a belief about the probability that the desire will be fulfilled. Imagination and anticipation are as well components of hope. I also discuss if hope implies orientation (...) to action. In the second part, I examine the concept of false hope. I show that hope is false if it cannot be justified epistemically. There is, I argue, an intimate relation between false hope and ignorance. Hope is justified—“realistic”—when the hoping person knows and accepts experts’ judgement about the probability of hope fulfillment. I then argue that what matters for evaluating a person’s hope is not only whether it is realistic, but also whether it is reasonable in the light of the aim and goals that a person strives for in his life. Part three goes into the question of what is morally wrong about having or causing false hope. In the fourth part, the relevance is shown of the insights from the previous parts for the debate on false hope in medicine and clinical research. (shrink)

Empirische Ethik ist ein relativ neues Vorgehen in der Ethikforschung, das vor allem in der Medizinethik angewandt wird. Dieser Beitrag bespricht die kennzeichnenden Charakteristika der empirischen Ethik und unterscheidet zwischen generalistischer und kontextualistischer empirischer Ethik. Zuerst werden verschiedene Beispiele beider Arten von empirischer Ethik vorgestellt, danach werden für beide Ansätze mögliche Schwachpunkte diskutiert. Die Schlussfolgerung des Beitrages besteht darin, dass das Entstehen der empirischen Ethik eine positive Entwicklung ist. Empirische Ethik sollte jedoch als eine Ergänzung der traditionellen philosophischen Medizinethik betrachtet (...) werden, und nicht als die bessere Alternative. (shrink)

Purpose The purpose of this paper is to develop an ethical framework for the marketing of corporate social responsibility. Methods The approach is a conceptual one based on virtue ethics and on the corporate identity literature. Furthermore, empirical research results are used to describe the opportunities and pitfalls of using marketing communication tools in the strategy of building a virtuous corporate brand. Results/conclusions An ethical framework that addresses the paradoxical relation between the consequentialist perspective many proponents of the marketing of (...) CSR adopt, and ethical perspectives which criticize an exclusive profit-oriented approach to CSR. Furthermore, three CSR strategies in relation to the marketing of CSR are discussed. For each CSR strategy it is explored how a corporation could avoid falling into the promise/performance gap. (shrink)

Today, mechanisms and mechanistic explanation are very popular in philosophy of science and are deemed a welcome alternative to laws of nature and deductive‐nomological explanation. Starting from Mitchell's pragmatic notion of laws, I cast doubt on their status as a genuine alternative. I argue that (1) all complex‐systems mechanisms ontologically must rely on stable regularities, while (2) the reverse need not hold. Analogously, (3) models of mechanisms must incorporate pragmatic laws, while (4) such laws themselves need not always refer to (...) underlying mechanisms. Finally, I show that Mitchell's account is more encompassing than the mechanistic account *Received August 2008; revised January 2010. †To contact the author, please write to: Centre for Logic and Philosophy of Science, Ghent University, Blandijnberg 2, B‐9000 Belgium; e‐mail: Bert[email protected].

We analyze ethical policies of firms in industrialized countries and try to find out whether culture is a factor that plays a significant role in explaining country differences. We look into the firm’s human rights policy, its governance of bribery and corruption, and the comprehensiveness, implementation and communication of its codes of ethics. We use a dataset on ethical policies of almost 2,700 firms in 24 countries. We find that there are significant differences among ethical policies of firms headquartered in (...) different countries. When we associate these ethical policies with Hofstede’s cultural indicators, we find that individualism and uncertainty avoidance are positively associated with a firm’s ethical policies, whereas masculinity and power distance are negatively related to these policies.

I approach the study of echo chambers from the perspective of veritistic social epistemology. A trichotomous belief model is developed featuring a mechanism by which agents will have a tendency to form agreement in the community. The model is implemented as an agent-based model in NetLogo and then used to investigate a social practice called Impartiality, which is a plausible means for resisting or dismantling echo chambers. The implementation exposes additional factors that need close consideration in an evaluation of Impartiality. (...) In particular, resisting or dismantling echo chambers requires the selection of sufficiently low levels of doxastic entrenchment, but this comes with other tradeoffs. (shrink)

Finance is grease to the economy. Therefore, we assume that it may affect corporate social responsibility (CSR) and the sustainability of economic development too. This paper discusses the transmission mechanisms between finance and sustainability. We find that there is no simple one-to-one relationship between financial development and sustainable development but there are various – often indirect – linkages. It appears that most of the literature concentrates on the role of public shareholders when it comes to changing corporate policy and performance (...) in a more sustainable direction. However, this focus neglects the potential impact of the credit channel and private equity on a firm’s non-financial policies and performance. These very powerful mechanisms can govern business policies and practices. Therefore, there appears to be much more scope for finance to promote socially and environmentally desirable activities and to discourage detrimental activities than has been acknowledged in the academic literature so far.

In clinical moral decision making, emotions often play an important role. However, many clinical ethicists are ignorant, suspicious or even critical of the role of emotions in making moral decisions and in reflecting on them. This raises practical and theoretical questions about the understanding and use of emotions in clinical ethics support services. This paper presents an Aristotelian view on emotions and describes its application in the practice of moral case deliberation.According to Aristotle, emotions are an original and integral part (...) of (virtue) ethics. Emotions are an inherent part of our moral reasoning and being, and therefore they should be an inherent part of any moral deliberation. Based on Aristotle's view, we examine five specific aspects of emotions: the description of emotions, the attitude towards emotions, the thoughts present in emotions, the reliability of emotions, and the reasonable principle that guides an emotion. We then discuss three ways of dealing with emotions in the process of moral case deliberation. Finally, we present an Aristotelian conversation method, and present practical experiences using this method. (shrink)
