This paper explores the relationship of various trait emotions to the ethical choices of 189 college students who completed a managerial decision-making task as part of an in-basket exercise in a laboratory setting. Prior research regarding emotion influences on ethical decision-making and linkages between emotions and cognition informed hypotheses about how different types of emotions impact ethical choices. Findings supported our expectations that positive and negative emotions classified as active would be more strongly related to interpersonally-directed ethical choices than to (...) organizationally-directed ones, and that passive emotions would be less related to ethical choices than active emotions. Implications for ethical decision-making research and organizational practices are discussed. (shrink)

Physicians make some medical decisions without disclosure to their patients. Nondisclosure is possible because these are silent decisions to refrain from screening, diagnostic or therapeutic interventions. Nondisclosure is ethically permissible when the usual presumption that the patient should be involved in decisions is defeated by considerations of clinical utility or patient emotional and physical well-being. Some silent decisions - not all - are ethically justified by this standard. Justified silent decisions are typically dependent on the physician's professional judgment, experience and (...) knowledge, and are not likely to be changed by patient preferences. We condemn the inappropriate exclusion of the patient from the decision-making process. However, if a test or treatment is unlikely to yield a net benefit, disclosure and discussion are at times unnecessary. Appropriate silent decisions are ethically justified by such considerations as patient benefit or economy of time. (shrink)

Editors’ Note:As a matter of policy, the editors believe that publishing several reviews of selected texts is a valuable exercise which will enable a cross-section of views to be aired. The recently published second edition of the National Academy of Sciences’ report “On Being a Scientist” was considered an appropriate text for such treatment. The reviewer, Kenneth D. Pimple, Ph.D., is a Research Associate at the Poynter Center for the Study of Ethics and American Institutions and a Visiting Lecturer in (...) the American Studies Program, both at Indiana University. He has been involved with training faculty members to teach ethics since 1989 and is the project director of “Teaching Research Ethics: A Workshop at Indiana University,” with funding from the Department of Education’s Fund for the Improvement of Postsecondary Education. Her interests include nerve development and regeneration. Her research is in the area of analytical chemistry and emphasizes spectroscopic techniques. (shrink)

While improving the theoretical account of base-rate neglect, Barbey & Sloman's (B&S's) target article suffers from affect neglect by failing to consider the fundamental role of emotional processes in decisions. We illustrate how affective influences are fundamental to decision making, and discuss how the dual process model can be a useful framework for understanding hot and cold cognition in reasoning.

In this article the results of a study of psychological readiness of pregnant women to parenthood are presented. Psychological readiness is defined as a structure consisting of three components: the cognitive, emotional, and behavioral, which is consistent with the single theory of psychological processes L. M. Vekkera. It was found that the main component that determines the high level of psychological readiness for motherhood is a cognitive component. The content of the cognitive component includes an understanding of the child as (...) a value. Some results of the research of value orientations of pregnant women in the structure of psychological readiness for parenthood. To identify the value system of pregnant women, the method of ‘Value Orientations‘ by M. Rokich was applied. The analysis of empirical data was performed using factor analysis and U criterion of Mann-Whitney. Respondents were distributed into two age groups: first group of 21-25 years, second group of 26-30 years. All women are nulliparous. The younger age group of pregnant women is characterized by values that are directed at the outside world. Emotional component dominates in the structure of psychological readiness for motherhood. Values of women in the second group are aimed at children. Cognitive and behavioral components dominate in the structure of their psychological readiness for motherhood. Knowledge of the structure of psychological readiness of women to parenthood will help to diagnose disorders of maternal behavior, to design methods of its correction and prevention. (shrink)

BackgroundThe demand for peer reviewers is often perceived as disproportionate to the supply and availability of reviewers. Considering characteristics associated with peer review behaviour can allow for the development of solutions to manage the growing demand for peer reviewers. The objective of this research was to compare characteristics among two groups of reviewers registered in Publons.MethodsA descriptive cross-sectional study design was used to compare characteristics between individuals completing at least 100 peer reviews from January 2018 to December 2018 as and (...) a control group of peer reviewers completing between 1 and 18 peer reviews over the same time period. Data was provided by Publons, which offers a repository of peer reviewer activities in addition to tracking peer reviewer publications and research metrics. Mann Whitney tests and chi-square tests were conducted comparing characteristics of mega peer reviewers to the control group of reviewers.ResultsA total of 1596 peer reviewers had data provided by Publons. A total of 396 M peer reviewers and a random sample of 1200 control group reviewers were included. A greater proportion of mega peer reviews were male as compared to the control reviewers. Mega peer reviewers demonstrated a significantly greater average number of total publications, citations, receipt of Publons awards, and a higher average h index as compared to the control group of reviewers.ConclusionsMega peer reviewers registered in the Publons database also had a higher number of publications and citations as compared to a control group of reviewers. Additional research that considers motivations associated with peer review behaviour should be conducted to help inform peer reviewing activity. (shrink)

I develop and defend the view that subjects are necessarily psychologically able to revise their beliefs in response to relevant counter-evidence. Specifically, subjects can revise their beliefs in response to relevant counter-evidence, given their current psychological mechanisms and skills. If a subject lacks this ability, then the mental state in question is not a belief, though it may be some other kind of cognitive attitude, such as a supposition, an entertained thought, or a pretense. The result is a moderately revisionary (...) view of belief: while most mental states we thought were beliefs are beliefs, some mental states which we thought were beliefs are not beliefs. The argument for this view draws on two key claims: First, subjects are rationally obligated to revise their beliefs in response to relevant counter-evidence. Second, if some subject is rationally obligated to revise one of her mental states, then that subject can revise that mental state, given her current psychological mechanisms and skills. Along the way to defending these claims, I argue that rational obligations can govern activities which reflect on one’s rational character, whether or not those activities are under one’s voluntary control. I also show how the relevant version of epistemic ‘ought’ implies ‘can’ survives an objection which plagues other variants of the principle. (shrink)

Hot-cold empathy gaps are a pervasive phenomena wherein one’s predictions about others tend to skew ‘in the direction’ of one’s own current visceral states. For instance, when one predicts how hungry someone else is, one’s prediction will tend to reflect one’s own current hunger state. These gaps also obtain intrapersonally, when one attempts to predict what one oneself would do at a different time. In this paper, we do three things: We draw on empirical evidence to argue that so-called hot-cold (...) empathy gaps arise when one projects one’s own current state into a simulation about another. Second, we argue that this process does not typically confer knowledge, even when the predictions it produces happen to be accurate. Third, we suggest that these results can be used to develop a challenge for L.A. Paul's view that authentic action sometimes requires subjective knowledge of one’s own values and how these values relate to relevant outcomes. We then sketch an alternative view of the epistemic grounds of authenticity, one on which authenticity requires a kind of understanding. The relevant form of understanding can be achieved by subjective knowledge but can also be achieved elsewise, such as through testimony from a close friend about what one values. (shrink)

I show that some of the most initially attractive routes of refuting epistemological solipsism face serious obstacles. I also argue that for creatures like ourselves, solipsism is a genuine form of external world skepticism. I suggest that together these claims suggest the following morals: No proposed solution to external world skepticism can succeed which does not also solve the problem of epistemological solipsism. And, more tentatively: In assessing proposed solutions to external world skepticism, epistemologists should explicitly consider whether those solutions (...) extend to knowledge of other minds. Finally, and also tentatively: epistemological solipsism warrants more philosophical attention than it currently enjoys. (shrink)

It is widely presumed that intuitions about thought experiments can help overturn philosophical theories. It is also widely presumed, albeit implicitly, that if thought experiments play any epistemic role in overturning philosophical theories, it is via intuition. In this paper, I argue for a different, neglected epistemic role of philosophical thought experiments, that of improving some reasoner’s appreciation both of what a theory’s predictions consist in and of how those predictions tie to elements of the theory. I call this role (...) theory clarification. I show that theory clarification does not proceed via intuition, and I argue that it is only in conjunction with theory clarification that intuitions about thought experiments can help overturn philosophical theories. I close by sketching how a more radical view might be true, on which thought experiments help justify the rejection of philosophical theories exclusively by clarifying theories, not by any intuitions those thought experiments might generate.

Although corporate social responsibility appears to be mutually beneficial for companies and consumers, the modern marketplace has left both parties in vulnerable positions. Consumers are increasingly subjected to incongruent CSR messages such as greenwashing, while companies are trapped in a strategic positioning dilemma with regard to how to most effectively and ethically approach CSR communication. This has led some companies to instead adopt a strategically silent approach, such as greenhushing. To capture this CSR positioning dilemma and test the positioning effects (...) on consumers’ attributions, this study applies attribution theory to conceptualize four distinct CSR positions which reflect varying combinations of congruence or incongruence between a company’s external CSR communication and its actual internal CSR actions. Using an online experiment, the effects of the CSR positions on consumer attributions for intrinsic and extrinsic CSR motivations and purchase intentions were tested across three CSR domains: environmental; labor; and lesbian, gay, bisexual, and transgender inclusion. Overall, the findings attest to the significant effect of internal–external congruence-based CSR positioning on how consumers respond to CSR communication. Importantly, the results indicate that discreet positioning is perceived similarly to uniform positioning, while misleading and unethical tactics such as CSR-washing are sure to backfire. Theoretical and managerial implications are discussed. (shrink)

We investigated the properties of the sustained attention to response task . In the SART, participants respond to frequent neutral signals and are required to withhold response to rare critical signals. We examined whether SART performance shows characteristics of speed–accuracy tradeoffs and in addition, we examined whether SART performance is influenced by prior exposure to emotional picture stimuli. Thirty-six participants in this study performed SARTs after being exposed to neutral and negative picture stimuli. Performance in the SART changed rapidly over (...) time and there was a high correlation between participants errors of commission rate and their reaction time to the neutral targets . Regardless of exposure self-reported thoughts significantly correlated with both errors of commission and reaction times. Overall, the results support the view that the SART is a better measure of impulsive responding than sustained attention. (shrink)

Small family businesses have generally been shown to exhibit significant concern for social responsibility, especially at the community level. Despite the reported heterogeneity of family firms in their preferences for and participation in social responsibility, the drivers of such differences are not agreed upon in the literature. We draw from enlightened self-interest and social capital theories by exploring their complementary and competing implications for the effect of duration and community satisfaction on participation in community-oriented social responsibility. Additionally, drawing on the (...) association between gender and self-construal and evidence that gender shapes helping and giving behaviors, we assess the moderating role of the gender of the firm manager in these relationships. We test our hypotheses on a sample of 279 family businesses and find support that gender moderates the relationship between community duration and satisfaction and measures of CSR. (shrink)

Recently, several theorists have proposed that we can perceive a range of high-level features, including natural kind features (e.g., being a lemur), artifactual features (e.g., being a mandolin), and the emotional features of others (e.g., being surprised). I clarify the claim that we perceive high-level features and suggest one overlooked reason this claim matters: it would dramatically expand the range of actions perception-based theories of action might explain. I then describe the influential phenomenal contrast method of arguing for high-level perception (...) and discuss some of the objections that have been raised against this strategy. Finally, I describe two emerging defenses of high-level perception, one of which appeals to a certain class of perceptual deficits and one of which appeals to adaptation effects. I sketch a challenge for the latter approach. (shrink)

Amodal completion is the representation of occluded parts of perceived objects. We argue for the following three claims: First, at least some amodal completion-involved experiences can ground knowledge about the occluded portions of perceived objects. Second, at least some instances of amodal completion-grounded knowledge are not sensitive, that is, it is not the case that in the nearest worlds in which the relevant claim is false, that claim is not believed true. Third, at least some instances of amodal completion-grounded knowledge (...) are not safe, that is, it is not the case that in all or nearly all near worlds where the relevant claim is believed true, that claim is in fact true. Thus, certain instances of amodal completion-grounded knowledge refute both the view that knowledge is necessarily sensitive and the view that knowledge is necessarily safe. (shrink)

I argue that we sometimes visually perceive the intentions of others. Just as we can see something as blue or as moving to the left, so too can we see someone as intending to evade detection or as aiming to traverse a physical obstacle. I consider the typical subject presented with the Heider and Simmel movie, a widely studied ‘animacy’ stimulus, and I argue that this subject mentally attributes proximal intentions to some of the objects in the movie. I further (...) argue that these attributions are unrevisable in a certain sense and that this result can be used to as part of an argument that these attributions are not post-perceptual thoughts. Finally, I suggest that if these attributions are visual experiences, and more particularly visual illusions, their unrevisability can be satisfyingly explained, by appealing to the mechanisms which underlie visual illusions more generally.

A presente pesquisa objetiva discutir a leitura de Karl Popper sobre os escritos de Francis Bacon no que concerne ao método científico. Popper afirma que Bacon é um puro empirista, na medida em que o filósofo inglês sugere a indução como método seguro à ciência, e concebe as teorias científicas a partir da observação direta da natureza, ou seja, a partir da experiência. Mas será mesmo que Bacon pode ser considerado um puro empirista como afirma Popper? Na tentativa de responder (...) a esta questão, apresentar-se-á leituras de comentadores de Bacon para que se possa contrapor às ideias de Popper. Nossa hipótese é de que a interpretação de Popper é válida, uma vez que se baseia em preceitos lógicos, porém acreditamos que sua análise desconsidera partes das obras de Bacon que fundamentam a interpretação de que este não pode ser considerado um puro empirista.

O presente artigo tem como objetivo analisar a interpretação de Popper acerca de um suposto antiteoricismo, que se manifesta na ideia de purificação da mente e na defesa da observação como ponto inicial da ciência, em Francis Bacon. Popper considera que tal posição antiteórica, a que deu o nome de “observacionismo”, supervaloriza o papel da observação no método científico. Procuramos discutir se Bacon realmente assume tal posição e em quais circunstâncias a leitura popperiana é possível. Nossa hipótese é de que (...) o filósofo inglês não pode ser considerado um antiteoricista e, portanto, um defensor do empirismo ingênuo. Dessa maneira, iremos expor a posição de Popper e depois contestá-la com auxílio de comentadores especializados na teoria baconiana. (shrink)

This paper examines an ancient debate over the rationality of perception. What leads the Stoics to affirm, and the Epicureans to deny, that to form a sense-impression is an activity of reason? The answer, we argue, lies in a disagreement over what is required for epistemic success. For the Stoics, epistemic success consists in believing the right propositions, and only rational states, in virtue of their predicational structure, put us in touch with propositions. Since they identify some sense-impressions as criteria (...) of truth and thus as the basis for epistemic success, the Stoics maintain that sense-impressions must be rational. The Epicureans agree with the Stoics that sense-impressions function as criteria of truth, and also agree broadly on what it means for a state to be rational, but deny that sense-impressions are rational because (1) they think that epistemic success must be supported by a state that is necessarily error-free and (2) accept that rational states can be false. In reconstructing this debate, we refine the standard interpretation of the fundamental difference between Epicurean and Stoic epistemology and also develop parallels with epistemological debates today. One upshot is a more nuanced appreciation of the merits of Epicurean epistemology vis-à-vis the Stoics. (shrink)

(Draft of Feb 2023, see upcoming issue for Chalmers' reply) In Reality+: Virtual Worlds and the Problems of Philosophy, David Chalmers argues, among other things, that: if we are living in a full-scale simulation, we would still enjoy broad swathes of knowledge about non-psychological entities, such as atoms and shrubs; and, our lives might still be deeply meaningful. Chalmers views these claims as at least weakly connected: The former claim helps forestall a concern that if objects in the simulation are (...) not genuine (and so not knowable), then life in the simulation is illusory and therefore, not as valuable as a non-simulated life. Taking up these questions, I argue that in general, the value of social knowledge for a meaningful life dramatically swamps the value of non-social knowledge for a meaningful life. Along the way, I propose a non-additive model of the meaningfulness of life, according to which the overall effect of some potential contributor of value to a life depends in part on what is already in a life. One upshot is that the vindication of non-social knowledge, absent a correlative vindication of social knowledge, contributes either not at all or scarcely at all to the claim that our lives in the simulation might be deeply meaningful. This is so even though the vindication of non-social knowledge does forestall the concern that in the simulation, our lives might be wholly meaningless. (shrink)

In this paper, I argue that the temporal openness of perceptual experience provides insight into the basic structure of learning. I draw on Husserl's account of the mutability of the retained past in Analyses Concerning Passive and Active Synthesis, and Merleau‐Ponty's account of the perceptual field, as well as his remarks on habit, in Phenomenology of Perception, in order to elucidate the relation between the perceptual past and the future it portends. More specifically, I argue that retention and habituation in (...) perceptual experience open dimensions of meaning that transform the initial, initiating, experiences in which meaning is first established. As a result, our experience of meaning is always subject to further development that we cannot anticipate. This temporal openness has consequences for our learning to navigate a perceptual field, but also, I argue, for our developing more complex ways of engaging with the world. Specifically, I show how learning requires that we commit ourselves to an object or task before we are in a position to recognize the implications or significance of our commitment. I further consider the role that others play in the inherent openness of learning to the development of new meaning. (shrink)

Cet article relève une impasse qui apparaît quand les travaux récents sur la suspension du jugement sont intégrés aux solutions évidentialistes au problème de la «mauvaise sorte de raison» : il semble qu’il n’existe aucune raison pour suspendre le jugement. Deux réponses possibles à cette impasse sont considérées ici : l’une redéfinit la suspension du jugement comme une action mentale, l’autre la redéfinit comme une attitude de second ordre. L’article fait valoir que ces réponses n’évitent l’impasse qu’en compromettant de manière (...) inacceptable la notion de suspension du jugement. (shrink)

At the end of the Meno, the character Socrates claims that true doxa is distinguished from epistēmē by a working out of the explanation. This chapter argues that working out the explanation consists, for Socrates, in seeing how the fact to be explained is grounded in facts about the natures of the relevant fundamental entities of the domain to which it belongs. It reconstructs the resulting conception of epistēmē. Once that reconstruction is complete, it argues that notions of epistemic justification (...) are out of place in interpreting the Meno. It then appeals to recent work in epistemology to settle the long-standing question of whether Socrates' account of epistēmē is better interpreted as an account of knowledge or as an account of understanding, arguing that it is more charitably taken in the latter way. Moreover, the chapter notes that Socrates' account of epistēmē provides insights that any philosopher interested in the nature of understanding should take seriously. (shrink)

The aim of this paper is to argue that there is no unproblematic way of delineating perceptual beliefs from non-perceptual beliefs. The concept of perceptual belief is one of the central concepts not only of philosophy of perception but also of epistemology in a broad foundationalist tradition. Philosophers of perception talk about perceptual belief as the interface between perception and cognition and foundationalist epistemologists understand perceptual justification as a relation between perceptual states and perceptual beliefs. We consider three ways of (...) cashing out the difference between perceptual and non-perceptual beliefs (semantic, justificatory, and etiological) and argue that none of them works. Finally, we explore the possibility of understanding perceptual justification without relying on the concept of perceptual beliefs. (shrink)

Withholding or withdrawing life-saving ventilators can become necessary when resources are insufficient. With rising cases in many countries, and likely further peaks in the coming colder seasons, ventilator triage guidance remains a central part of the COVID-19 policy response. The dominant model in ventilator triage guidelines prioritises the ethical principles of saving the most lives and saving the most life-years. We sought to ascertain to what extent this focus aligns, or conflicts, with the preferences of disadvantaged minority populations. We conducted (...) a bibliographical search of PubMed and Google Scholar and reviewed all ventilator rationing guidelines included in major recent systematic reviews, yielding 589 studies before screening. Post screening, we found six studies comprising a total of 10 591 participants, with 1247 from disadvantaged populations. Three studies reported findings stratified by race and age, two of which stratified by income. Studies included two to seven principles; all included ‘save the most lives’. Involvement of disadvantaged minority populations in eliciting preferences is very limited; few studies capture race and income. This is concerning, as despite relatively small numbers and framing effects there is an observable and plausible trend suggesting that disadvantaged groups worry that dominant principles reduce their chances of receiving a ventilator. To avoid compounding prior historical and structural disadvantage, policy makers need to engage more fully with these populations in designing and justifying ventilator rationing guidance and review their adequacy. Likewise, clinicians need to be aware that their implementation of dominant triage guidelines is viewed with higher levels of concern by minority populations. (shrink)

We examine two connectionist networks—a fractal learning neural network (FLNN) and a Simple Recurrent Network (SRN)—that are trained to process center-embedded symbol sequences. Previous work provides evidence that connectionist networks trained on infinite-state languages tend to form fractal encodings. Most such work focuses on simple counting recursion cases (e.g., anbn), which are not comparable to the complex recursive patterns seen in natural language syntax. Here, we consider exponential state growth cases (including mirror recursion), describe a new training scheme that seems (...) to facilitate learning, and note that the connectionist learning of these cases has a continuous metamorphosis property that looks very different from what is achievable with symbolic encodings. We identify a property—ragged progressive generalization—which helps make this difference clearer. We suggest two conclusions. First, the fractal analysis of these more complex learning cases reveals the possibility of comparing connectionist networks and symbolic models of grammatical structure in a principled way—this helps remove the black box character of connectionist networks and indicates how the theory they support is different from symbolic approaches. Second, the findings indicate the value of future, linked mathematical and empirical work on these models—something that is more possible now than it was 10 years ago. (shrink)

did plato and aristotle have anything to say about belief? The answer to this question might seem blindingly obvious: of course they did. Plato distinguishes belief from knowledge in the Meno, Republic, and Theaetetus, and Aristotle does so in the Posterior Analytics. Plato distinguishes belief from perception in the Theaetetus, and Aristotle does so in the De anima. They talk about the distinction between true and false beliefs, and the ways in which belief can mislead and the ways in which (...) it can steer us aright. Indeed, they make belief a central component of their epistemologies.The view underlying these claims—one so widespread these days as to remain largely unquestioned—is that when Plato and Aristotle talk...

Recollection is central to the epistemology of Plato’sMeno. After all, the character Socrates claims that recollection is the process whereby embodied human souls bind down true opinions (doxai) and acquire knowledge (epistêmê). This paper examines the exchange between Socrates and Meno’s slave to determine (1) what steps on the path to acquiring knowledge are part of the process of recollection and (2) what is required for a subject to count as having recollected something. I argue that the key to answering (...) these questions is to get clear on the kind of process recollection is supposed to be. In particular, I argue that recollection is a process akin to the kind of process Aristotle calls “changes” (kinêseisor incompleteenergeiai). The key feature of such processes is that they aim at an end beyond themselves and are not complete until that end comes about. In the case of recollection, the end is knowledge, but inferior mental states, such as false opinion, puzzlement (aporia), and true opinion can come about because of a process of recollection without making it the case that the subject has recollected anything. I argue that this interpretation provides a textually supported and philosophically coherent understanding of Socrates’ conception of recollection. (shrink)

The Sustained Attention to Response Task is a Go–No-Go signal detection task developed to measure lapses of sustained conscious attention. In this study, we examined the impact global interference and spatial uncertainty has on SART performance. Ten participants performed either a SART or a traditionally formatted version of a global–local stimuli detection task with spatially certain and uncertain signals. Reaction time in the SART was insensitive to global interference and spatial uncertainty, whereas reaction time in the low-Go task was sensitive. (...) Spatial uncertainty increased errors of omission in the SART, which was not expected if the SART measures mindlessness. There was a high correlation between participants’ errors of commission rate and their reaction time in the SART. The results, overall, support the view that the SART is a better measure of response strategy than lapses in sustained attention or mindlessness. (shrink)

The present study was designed to explore the performance costs of negative emotional stimuli in a vigilance task. Forty participants performed a vigilance task in two conditions: one with task-irrelevant negative-arousing pictures and one with task-irrelevant neutral pictures. In addition to performance, we measured subjective state and frontal cerebral activity with near infrared spectroscopy. Overall performance in the negative picture condition was lower than in the neutral picture condition and the negative picture condition had elevated levels of energetic arousal, tense (...) arousal and task-related thoughts. Moreover, there was a significant relationship between the impact of the negative pictures on tense arousal and task-related thoughts and the impact of the negative pictures on performance . These results provide support for indirect cost models of negative emotional stimuli on target detection performance. (shrink)
