The method of positron emission tomography (PET imaging) illustrates the circular logic popular in subtractive neuroimaging and linear reductive cognitive psychology. Both require that strictly feed-forward, modular, cognitive components exist, before the fact, to justify the inference of particular components from images (or other observables) after the fact. Also, both require a "true" componential theory of cognition and laboratory tasks, before the fact, to guarantee reliable choices for subtractive contrasts. None of these possibilities are likely. Consequently, linear reductive analysis has (...) failed to yield general, reliable, componential accounts. (shrink)

Brain damage may doubly dissociate cognitive modules, but the practice of revealing dissociations is predicated on modularity being true (T. Shallice, 1988). This article questions the utility of assuming modularity, as it examines a paradigmatic double dissociation of reading modules. Reading modules illustrate two general problems. First, modularity fails to converge on a fixed set of exclusionary criteria that define pure cases. As a consequence, competing modular theories force perennial quests for purer cases, which simply perpetuates growth in the list (...) of exclusionary criteria. The first problem leads, in part, to the second problem. Modularity fails to converge on a fixed set of pure cases. The second failure perpetuates unending fractionation into more modules. (shrink)

Borrett, Kelly and Kwan [ Phenomenology, dynamical neural networks and brain function, Philosophical Psychology, 13, 000-000] claim that unbiased, self-evident, direct description is possible, and may supply the data that brain theories account for. Merleau-Ponty's [ Phenomenology of perception, London: Routledge] description of Schneider's apraxia is offered as a case in point. According to the authors, Schneider's apraxia justifies brain components of predicative and pre-predicative experience. The description derives from a bias, however, that parallels modularity's morphological reduction. The presence of (...) biasing presuppositions contradicts the goal of direct description. Moreover, the authors' brain account is not necessary to explain Schneider's apraxia, and morphological reduction is not sufficient to explain emergent phenomena of motor control. (shrink)

The suggestion of seeking specificity in a higher-order array is attractive, but Stoffregen & Bardy fail to provide a compelling empirical basis to their claim that specificity exists solely in the global array. Using the example of relative motion, the alternate hypotheses that must be considered are presented.

Models are not adequately evaluated simply by whether they capture the data, after the fact. Other criteria are needed. One criterion is parsimony; but utility and generality are at least as important. Even with respect to parsimony, however, the case against feedback is not as straightforward as Norris et al. present it. We use feedback consistency effects to illustrate these points.

Human neural and behavioral activities have been reported to exhibit fractal dynamics known as 1/f noise, which is more aptly named 1/f scaling. Some argue that 1/f scaling is a general and pervasive property of the dynamical substrate from which cognitive functions are formed. Others argue that it is an idiosyncratic property of domain‐specific processes. An experiment was conducted to investigate whether 1/f scaling pervades the intrinsic fluctuations of a spoken word. Ten participants each repeated the word bucket over 1,000 (...) times, and fluctuations in acoustic measurements across repetitions generally followed the 1/f scaling relation, including numerous parallel yet distinct series of 1/f fluctuations. On the basis of work showing that 1/f scaling is a universal earmark of metastability, it is proposed that the observed pervasiveness of 1/f fluctuations in speech reflects the fact that cognitive functions are formed as metastable patterns of activity in brain, body, and environment.

The Theory of Planned Behavior predicts that a combination of attitudes, perceived norms, and perceived behavioral control predict intentions, and that intentions ultimately predict behavior. Previous studies have found that the TPB can predict students’ engagement in plagiarism. Furthermore, the General Theory of Crime suggests that self-control is particularly important in predicting engagement in unethical behavior such as plagiarism. In Study 1, we incorporated self-control in a TPB model and tested whether norms, attitudes, and self-control predicted intention to plagiarize and (...) plagiarism behavior. The best statistical fit for the path-analytic model was achieved when a direct path from self-control to plagiarism engagement was specified. In Study 2, we added a measure of perceived behavioral control and split the measurement of norms into descriptive and injunctive components. This study found that both self-control and perceived-behavioral control additively contributed to the prediction of plagiarism and the path-analytic model achieved its best fit when direct paths from perceived norms to plagiarism behavior were specified. These studies suggest that setting strong anti-plagiarism norms, such as by the use of honor codes, and seeking to enhance students’ self-control may reduce engagement in plagiarism. (shrink)

Recent research has relied on trolley-type sacrificial moral dilemmas to study utilitarian versus nonutili- tarian modes of moral decision-making. This research has generated important insights into people’s attitudes toward instrumental harm—that is, the sacrifice of an individual to save a greater number. But this approach also has serious limitations. Most notably, it ignores the positive, altruistic core of utilitarianism, which is characterized by impartial concern for the well-being of everyone, whether near or far. Here, we develop, refine, and validate a (...) new scale—the Oxford Utilitarianism Scale—to dissociate individual differences in the ‘negative’ (permissive attitude toward instrumental harm) and ‘positive’ (impartial concern for the greater good) dimensions of utilitarian thinking as manifested in the general population. We show that these are two independent dimensions of proto-utilitarian tendencies in the lay population, each exhibiting a distinct psychological profile. Empathic concern, identification with the whole of humanity, and concern for future generations were positively associated with impartial beneficence but negatively associated with instrumental harm; and although instrumental harm was associated with subclinical psychopathy, impartial beneficence was associated with higher religiosity. Importantly, although these two dimensions were independent in the lay population, they were closely associated in a sample of moral philosophers. Acknowledging this dissociation between the instrumental harm and impartial beneficence components of utilitarian thinking in ordinary people can clarify existing debates about the nature of moral psychology and its relation to moral philosophy as well as generate fruitful avenues for further research.

Chronically disabling health impairments affect an increasing number of people worldwide. In close relationships, disability is an interpersonal experience. Psychological distress is thus common in patients as well as their spouses. Dyadic coping can alleviate stress and promote adjustment in couples who face disabling health impairments. Much research has focused on dyadic coping with cancer. However, other health problems such as physical and sensory impairments are also common and may strongly impact couple relationships. In order to promote couples' optimal adjustment (...) to impaired health, the identification of disability-related relationship challenges is required. Furthermore, ways in which dyadic coping with these challenges may benefit couples could inform researchers and practitioners how to support couples in coping with health impairments. Accordingly, the aims of this study were to systematically review dyadic challenges and dyadic coping when one partner has a chronically disabling physical or sensory impairment. Out of 873 articles identified through database searches, 36 studies met inclusion criteria. The disability-related dyadic challenges identified in the review were changed roles and responsibilities within the couple, altered communication, compromised sexual intimacy, and reduced social participation. These challenges were reported to burden both partners and the couple relationship. Dyadic adjustment benefitted from a we-perspective, i.e., when couples viewed the disability as a shared challenge and engaged in conjoint dyadic coping. The results suggest that patient/care recipient and partner/caregiver roles should be de-emphasized and that disability should be recognized as an interpersonal experience. (shrink)

Background: Moral case deliberation is a form of clinical ethics support to help healthcare professionals in dealing with ethically difficult situations. There is a lack of evidence about what outcomes healthcare professionals experience in daily practice after moral case deliberations. The Euro-MCD Instrument was developed to measure outcomes, based on the literature, a Delphi panel, and content validity testing. To examine relevance of items and adequateness of domains, a field study is needed. Aim: To describe experienced outcomes after participating in (...) a series of moral case deliberations, both during sessions and in daily practice, and to explore correlations between items to further validate the Euro-MCD Instrument. Methods: In Sweden, the Netherlands, and Norway, healthcare institutions that planned a series of moral case deliberations were invited. Closed responses were quantitatively analyzed. The factor structure of the instrument was tested using exploratory factor analyses. Ethical considerations: The study was approved in Sweden by a review board. In Norway and the Netherlands, data services and review boards were informed about the study. Results: The Euro-MCD Instrument was completed by 443 and 247 healthcare professionals after four and eight moral case deliberations, respectively. They experienced especially outcomes related to a better collaboration with co-workers and outcomes about individual moral reflexivity and attitude, both during sessions and in daily practice. Outcomes were experienced to a higher extent during sessions than in daily practice. The factor structure revealed four domains of outcomes, which did not confirm the six Euro-MCD domains. Conclusion: Field-testing the Euro-MCD Instrument showed the most frequently experienced outcomes and which outcomes correlated with each other. When revising the instrument, domains should be reconsidered, combined with theory about underlying concepts. In the future, a feasible and valid instrument will be presented to get insight into how moral case deliberation supports and improves healthcare. (shrink)

Deliberative ways of dealing with ethical issues in health care are expanding. Moral case deliberation is an example, providing group-wise, structured reflection on dilemmas from practice. Although moral case deliberation is well described in literature, aims and results of moral case deliberation sessions are unknown. This research shows (a) why managers introduce moral case deliberation and (b) what moral case deliberation participants experience as moral case deliberation results. A responsive evaluation was conducted, explicating moral case deliberation experiences by analysing aims (...) (N = 78) and harvest (N = 255). A naturalistic data collection included interviews with managers and evaluation questionnaires of moral case deliberation participants (nurses). From the analysis, moral case deliberation appeals for cooperation, team bonding, critical attitude towards routines and nurses’ empowerment. Differences are that managers aim to foster identity of the nursing profession, whereas nurses emphasize learning processes and understanding perspectives. We conclude that moral case deliberation influences team cooperation that cannot be controlled with traditional management tools, but requires time and dialogue. Exchanging aims and harvest between manager and team could result in co-creating (moral) practice in which improvements for daily cooperation result from bringing together perspectives of managers and team members.

Disturbance-generated biomass results from endogenous and exogenous natural and cultural disturbances that affect the health and productivity of forest ecosystems. These disturbances can create large quantities of plant biomass on predictable cycles. A systems analysis model has been developed to quantify aspects of system capacities (harvest, transportation, and processing), spatial aspects of the biomass generation process, and deterioration impacts on biomass quality in the various inventory states (field stands, field-harvested inventories, transportation prepared inventories, and production facility inventories). Optimal decision alternatives (...) can be used to guide responses to reclamation, utilization, mitigation, and control. This is particularly advantageous in insect and disease outbreaks, in which the process may last several years, with varying levels of intensity. The prescriptive system description, assuming capacities are fixed, results in a linear programming model. The time-dependent capacity decision model results in a mixed-integer programming model. The analytical model is developed in detail in this analysis. (shrink)

Sacrificial moral dilemmas are widely used to investigate when, how, and why people make judgments that are consistent with utilitarianism. But to what extent can responses to sacrificial dilemmas shed light on utilitarian decision making? We consider two key questions: First, how meaningful is the relationship between responses to sacrificial dilemmas and what is distinctive of a utilitarian approach to morality? Second, to what extent do findings about sacrificial dilemmas generalise to other moral contexts where there is tension between utilitarianism (...) and common-sense intuitions? We argue that sacrificial dilemmas only capture one point of conflict between utilitarianism and common-sense morality, and new paradigms are needed to investigate other key aspects of utilitarianism, such as its radical impartiality.

The purpose of this paper is to examine, from the point of view of C. S. Peirce's categories, the question whether there are real possibilities, such as those that are implicit in any moral statement suggesting that we could have acted differently. An inquiry into these categories shows that, according to Peirce, real possibilities are the truthmakers of a particular sort of general conditional statements.

Moral case deliberation (MCD) is a specific form of clinical ethics, aiming to stimulate ethical reflection in daily practice in order to improve the quality of care. This article focuses on the implementation of MCD in nursing homes and the questions how and where to organize MCD. The purpose of this study was to evaluate one way of organizing MCD in two Dutch nursing homes. In both of these nursing homes the MCD groups had a heterogeneous composition and were organized (...) apart from existing institutional communication structures. As part of a naturalistic evaluation, systematic observations, interviews and focus groups were completed. The findings indicate that the heterogeneous composition and MCD meetings separate from existing structures have benefits. However, the participants also reported negative experiences. This gives rise to the question whether a mixed MCD group which meets separately is an effective way to embed MCD as an instrument for reflection on moral issues in daily practice. We conclude that there is no single answer to that question. In the end, the two implementation strategies (i.e. within existing communication structures and a mixed MCD group) can be complementary to each other. (shrink)

L'ouvrage de Pesot, qui se veut une initiation à la sémiologie (ou sémiotique), consacre ses trois parties au domaine de cette discipline, à la notion de communication, puis à ses principaux théoriciens. Dans le premier cas, on montre que la notion de signe n'est pas suffisamment précise; que la description du champ de la sémiologie est insatisfaisante; et que la caractérisation de ses tendances laisse à désirer. Dans le second, on montre que la notion de code qu'il propose reste floue, (...) et que dissocier le code du processus général de la communication n'est pas justifié. Dans le troisième, on montre que, si mettre l'accent sur la pensée de Peirce n'est pas une mauvaise idée, se fonder sur une seule des trois périodes qui la caractérisent est une simplification inacceptable masquant son immense complexité.

Anglophone philosophers are often associated with rejecting philosophy’s moral guidance function after 1945. This article builds on existing work on Jean-Paul Sartre’s reception in universities to show that, actually, many British and U.S. philosophers embraced moral guidance roles by engaging with his work and that they promoted creativity and choice in society as a result. Sartre first came to philosophers’ attention in the context of post-war Francophilia, but interest in him quickly went beyond the fact that he was French and (...) expanded to include the wider existentialist movement that he was a part of. Sartre had enduring popularity among English-speaking philosophers because his philosophy resonated with the older British and U.S. philosophies of idealism and pragmatism that, like his, were inspired by Hegel. Sartre’s respondents also valued existentialism because, to them, it made certain Judeo-Christian principles relevant, thus protecting religion at a time when they believed it was threatened with decline and by the advance of specialisation. Anglophone philosophers who were interested in Sartre spread their responses to him through teaching an expanding student population, but also reached the wider public through activism, journalism, broadcasting, and government advisory roles. In doing so, philosophers integrated their interpretations of existential ideas into several aspects of culture in post-war Britain and U.S.A. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:THE STRUCTURES OF PRACTICAL REASON: SOME COMMENTS AND CLARIFICATIONS DR. BRIAN V. JOHNSTONE, C.Ss.R., pays particular attention to some of my early work in his recent article, " The Structures of Practical Reason: Traditional Theories and Contemporary Questions." 1 He plainly tries to present my views accurately. Still, Johnstone has overlooked some important things I said about the questions he considers. Moreover, in some cases he either misunderstands the (...) positions I tried to explain and defend or, at least, puts matters in ways likely to cause others to misunderstand those positions. They still seem sound to me, although no doubt open to refinement and development. Therefore, since Johnstone is.seriously trying to use my work to advance understanding of important questions, I offer these comments and clarifications to help keep open the way to a more adequate theory of practical reason. I. The first question Johnstone considers is: What is the specific truth of practical reason? To explore this question, he compares the theory of practical reason which I articulated with a " traditional" theory, exemplified by the work of Labourdette. E·arly in this comparison, in pointing out differences, Johnstone offers a summary and criticism: If I understand Grisez correctly, he seeks to develop a theory of practical reason such that practical reason, in itself, can be understood -must be understood-without reference to the will FP,2 1 Tkomist, 50 (1986), pp. 417-46. Johnstone's article will be referred to henceforth as BVJ. 2 FP refers to: Germain Grisez, "The First Principle of Practical Reason : A Commentary on the Summa tkeologiae, 1-2, Question 94, Article 2," 9t69 270 GERMAIN GRISEZ p. 193). Further, he places such stress on the distinct way of knowing proper to practical reason, that he implies that the two (practical and theoretical reason) are quite disparate. These distinctions, I would suggest, are too sharply drawn. (BVJ, p. 4~5) I agree with Johnstone in rejecting these positions, for, as formulated, neither is what I tried to explain and defend. For practical reason precisely is reason directed to a work, which will not be done without an intervening act of an appetitive power corresponding to reason, and that power is the will. Hence, volition is included in the very concept of practical reason, and so it cannot be understood without reference to the will. But in the place Johnstone cites (FP, p. 193), I did not say that practical reason can be understood without reference to the wilL Rather, having argued that, because practical principles are self-evident truths, they do not presuppose a divine command, I said: "Nor is any operation of our own will presupposed by the first principles of practical reason." The argument for this is: The first operations of will are natural volitions of ends; these volitions presuppose knowledge directing to these ends; the directive knowledge is the principles of practical reason; therefore, the principles of practical reason do not presuppose any operation of our will.3 Moreover, I pointed out: "Of course we do make judgments concerning means in accordance with the orientation of our inNatural Law Forum, 10 (1965), pp. 168-201. Although I personally agreed with all of the propositions asserted in this article at the time I wrote it, and still agree with almost all of them, I did not and do not consider the theory proposed in it to be my theory, but that of St. Thomas (and, even more importantly, a very good theory) which I tried to understand, explain, and defend. Moreover, had the article not been a commentary, I would have put many things somewhat differently, and would have provided arguments for certain positions which can be taken for granted within the Thomistic framework. s In FP, p. 193, this argument is introduced by the sentence: "At any rate this is Aquinas's theory," and accompanied by references to his work, to signal the reader that assumptions are being made here which outside the Thomistic framework would require additional support..Johnstone overlooks the signal.

The explanation of the suppression of Modus Ponens inferences within the framework of linguistic pragmatics and of plausible reasoning (i.e., deduction from uncertain premises) is defended. First, this approach is expounded, and then it is shown that the results of the first experiment of Byrne, Espino, and Santamar a (1999) support the uncertainty explanation but fail to support their counterexample explanation. Second, two experiments are presented. In the first one, aimed to refute one objection regarding the conclusions observed, the additional (...) conditional premise ( if N, C ) was replaced with a statement of uncertainty ( it is not certain that N ); the answers produced by the participants remained qualitatively and quantitatively similar in both conditions. In the second experiment, a fine-grained analysis of the responses to and justifications for an evaluation task was performed. The results of both experiments strongly supported the uncertainty explanation. (shrink)

A travers la lecture du Visible et de l ‘Invisible, Guy-Félix Duportail se propose de montrer que la notion de chair connaît une structure topologique que l’on peut expliciter sous la forme de trois principes élémentaires : indivision, division, et réversibilité.
