We present a new class of models of players’ reasoning in non-cooperative games, inspired by David Lewis's account of common knowledge. We argue that the models in this class formalize common knowledge of rationality in a way that is distinctive, in virtue of modelling steps of reasoning; and attractive, in virtue of being able to represent coherently common knowledge of any consistent standard of individual decision-theoretic rationality. We contrast our approach with that of Robert Aumann, arguing that the former (...) avoids and diagnoses certain paradoxes to which the latter may give rise when extended in particular ways. (shrink)

Change blindness illustrates a remarkable limitation in visual processing by demonstrating that substantial changes in a visual scene can go undetected. Because these changes can ultimately be detected using top–down driven search processes, many theories assign a central role to spatial attention in overcoming change blindness. Surprisingly, it has been reported that change blindness can occur during blink-contingent changes even when observers fixate the changing location [O’Regan, J. K., Deubel, H., Clark, J. J., & Rensink, R. A. . Picture changes (...) during blinks: Looking without seeing and seeing without looking. Visual Cognition, 7, 191–212]. However, eye blinks produce a transient disruption of vision that is independent of any associated changes in the retinal image. We determined whether these ‘attentive blank stares’ could occur in the absence of blink-mediated visual suppression. Using a flicker change-blindness paradigm we confirm that despite direct attentive fixations, obvious scene changes often remain undetected. We conclude that change detection involves object or feature based attentional mechanisms, which can be ‘misdirected’ despite the allocation of spatial attention to the position of the change.

Functionalists in philosophy of mind traditionally raise two major arguments against the type identity theory: (1) psychological states are _multiply realizable_ so that there are no one-to-one mappings of psychological states onto neural states and (2) the most that evidence could ever establish is the _correlation_ of psychological and neural states, not their identity. We defend a variant on the traditional type identity theory which we call _heuristic identity theory_ (HIT) against both of these objections. Drawing its inspiration from scientific (...) practice, heuristic identity theory construes identity claims as hypotheses that guide subsequent inquiry, not as conclusions of the research. (shrink)

This study explores corporate social responsibility (CSR) by conducting a cross-cultural analysis of communication of CSR activities in a total of 16 U.S. and European corporations. Drawing on previous research contrasting two major approaches to CSR initiatives, it was proposed that U.S. companies would tend to communicate about and justify CSR using economic or bottom-line terms and arguments whereas European companies would rely more heavily on language or theories of citizenship, corporate accountability, or moral commitment. Results supported this expectation of (...) difference, with some modification. Specifically, results indicated that EU companies do not value sustainability to the exclusion of financial elements, but instead project sustainability commitments in addition to financial commitments. Further, U.S.-based companies focused more heavily on financial justifications whereas EU-based companies incorporated both financial and sustainability elements in justifying their CSR activities. In addition, wide variance was found in both the prevalence and use of specific CSR-related terminology. Cross-cultural distinctions in this use create implications with regard to measurability and evidence of both strategic and bottom-line impact. Directions for further research are discussed.

In the clinical setting, questions of medical ethics raise a host of perplexing problems, often complicated by conflicting perspectives and the need to make immediate decisions. In this volume, bioethicists and physicians provide a nuanced, in-depth approach to the difficult issues involved in bioethics consultation. Addressing the needs of researchers, clinicians, and other health professionals on the front lines of bioethics practice, the contributors focus primarily on practical concerns -- whether ethics consultation is best done by individuals, teams, or committees (...) how an ethics consult service should be structured the need for institutional support and techniques and programs for educating and training staff -- without neglecting more theoretical considerations, such as the importance of character or the viability of organizational ethics.

We draw on the behavioral agency model to explore the ethical consequences of CEO equity incentives. We argue that CEOs are more concerned with funding pension plans when they have more to gain from their stock options yet will increasingly underfund employee pension funds as their current option wealth increases. Our findings reveal that both effects hold when the CEO has greater power (also occupying board chair) over firm decision making. Our study suggests that there is an ethical dimension to (...) equity incentives, given they are intended to align CEO interests with shareholders, yet potentially incentivize CEO behaviors with adverse consequences for employees. Insights from our findings provide boards and regulators with behavioral levers to protect employee well-being in the context of pension funding. (shrink)

Hertwig and Ortmann suggest methodological practices from economics (script enactment, repeated measures, performance based payments, and absence of deception) for psychology. Such prescriptive methodologies may be unrepresentative of real world behaviors because people are not: always behaving with complete information, monetarily rewarded for important activities, repeating tasks to perfection, aware of all contributing variables. These proscriptions, while useful in economics, may obfuscate important psychological phenomena.

Prestigious University is a large, private educational institution with a medical school, a university hospital, a law school, and graduate and undergraduate colleges all on a single campus. In the face of the Covid‐19 pandemic, students were told during spring break to return to campus only briefly to retrieve their belongings. Classes then went online. On March 23, 2020, the faculty, students, and staff were emailed the following by the university's director of infection control and public health: We have become (...) aware that a Prestigious University staff member has tested positive for the virus that causes Covid‐19. The individual, who was last on campus on March 16, is now in isolation at their permanent residence and is doing well clinically. The university has already identified those members of our community who may have been in close contact with this individual, and we are working to notify them. Further, this individual's local health department has a protocol for identifying people who have been in direct contact with anyone testing positive for Covid‐19 (such as this Prestigious University staff member) so that they can self‐quarantine and watch for COVID‐19 symptoms for a period of 14 days from their last contact with the infected individual.A professor in the Philosophy Department has asked the ethicists at the medical school whether such contact tracing suffices. “Don't the members of the community deserve to know who this is? Isn't there a mandate to identify this person in order to maximize public health benefits and slow the spread of this deadly virus?”. (shrink)

To say that the matter of the legality of the armed conflict against Iraq in 2003 was divisive is an understatement. The primary justification given by the UK government for the lawful nature of the Iraq war was an implied mandate from the Security Council. The implied mandate was said to be derived from a combination of Security Council Resolutions 678 and 1441. Many international lawyers remain unconvinced that such a mandate can be inferred from those resolutions. There is agreement (...) among both supporters and opponents of the war in Iraq that Saddam Hussein’s regime had an appalling human rights record. This was known to the coalition governments; indeed, Tony Blair expressly made the "moral case" for war on the basis of Hussein’s human rights violations. The legal justifications offered for the conflict by the UK government, however, did not refer to humanitarian intervention. This paper investigates whether it is possible that, despite the fact that the justification was not raised by the UK, it can provide a defence to any claims that the UK acted unlawfully, or that individuals committed an international crime, by initiating the attack on Iraq.

Here a group of philosophers, economists and political theorists discuss the work of David Gauthier, which seeks to show that rational individuals would accept certain moral constraints on their choices. The possibilities and limitations of a contractarian approach to issues of justice is analyzed.

The hypothesis that play behavior is more prevalent in larger-brained animals has recently been challenged. It may be, for example, that only certain brain structures are related to play. Here, we analyze social play behavior with regards to the cerebellum: a structure strongly implicated in motor-development, and possibly also in cognitive skills. We present an evolutionary analysis of social play and the cerebellum, using a phylogenetic comparative method. Social play frequency and relative cerebellum size are positively correlated. Hence, there appears (...) to be a link between the evolutionary elaboration of social play and the cerebellum. (shrink)

David Lewis is widely credited with the first formulation of common knowledge and the first rigorous analysis of convention. However, common knowledge and convention entered mainstream game theory only when they were formulated, later and independently, by other theorists. As a result, some of the most distinctive and valuable features of Lewis' game theory have been overlooked. We re-examine this theory by reconstructing key parts in a more formal way, extending it, and showing how it differs from more recent game (...) theory. In contrast to current theories of common knowledge, Lewis' theory is based on an explicit analysis of the modes of reasoning that are accessible to rational individuals and so can be used to analyse the genesis of common knowledge. Lewis' analysis of convention emphasises the role of inductive reasoning and of salience in the maintenance of conventions over time.

New research tools such as PET can produce dramatic results. But they can also produce dramatic artifacts. Why is PET to be trusted? We examine both the rationale that justifies interpreting PET as measuring brain activity and the strategies for interpreting PET results functionally. We show that functional ascriptions with PET make important assumptions and depend critically on relating PET results to those secured through other research techniques.

We introduce stellar photometry, its purpose and relationship to other astronomical quantities, presenting it within the context of astronomical research at the Vatican Observatory. We demonstrate the usefulness of the Vilnius Photometric System previously shown at Vilnius Astronomical Obs., Edinburgh Royal Obs., and Università di Roma “La Sapienza”, and then adopted by the Vatican Observatory for use with its Vatican Advanced Technology Telescope on Mount Graham, AZ, USA. The development of astronomical observations has led from photographic plates, through photoelectric detectors (...) to the use of sensitive CCD cameras. Expanding the photoelectric databank of “Vilnius Stars”, we describe the development of new techniques of data-acquisition, calibration to photometric standards, stellar classification and interstellar-matter characterization. Looking ahead, we briefly describe the extensive data set, and our plans for further detailed analyses. (shrink)

In “Bioethics and the Whole: Pluralism, Consensus, and the Transmutation of Bioethical Methods into Gold,” Patricia Martin identifies themes common to three emerging approaches to clinical bioethics--clinical pragmatism, ethics facilitation, and mediation-in order to develop an “ethical consensus method” that can serve as a “practical, step-by-step guide” for decision making She is to be applauded both for her identification of themes common to these three approaches and for her contribution to what we hope will be a growing literature on practical (...) methods for problem solving in clinical bioethics that take seriously the ideal of consensus. After a few preliminary remarks concerning Martin's working model, we focus the majority of our commentary on the notion of “consensus,” which is at the heart of her “ethical consensus method,” and the three approaches from which it is drawn.

Louis Pojman and Robert Westmoreland have compiled the best material on the subject of equality, ranging from classical works by Aristotle, Hobbes and Rousseau to contemporary works by John Rawls, Thomas Nagel, Michael Walzer, Harry Frankfurt, Bernard Williams and Robert Nozick; and including such topics as: the concept of equality; equal opportunity; Welfare egalitarianism; resources; equal human rights and complex equality.

At the time of this writing, a widely publicized, waived-consent trial is underway. Sponsored by Northfield Laboratories, Inc. (Evanston, IL) the trial is intended to evaluate the emergency use of PolyHeme®, an oxygen-carrying resuscitative fluid that might prevent deaths from uncontrolled bleeding. The protocol allows patients in hemorrhagic shock to be randomized between PolyHeme® and saline in the field and, still without consent, randomized between PolyHeme® and blood after arrival at an emergency department. The Federal regulations that govern the waiver (...) of consent restrict its applicability to circumstances where proven, satisfactory treatments are unavailable. Blood - the standard treatment for hemorrhagic shock - is not available in ambulances but is available in hospitals. The authors argue that the in-hospital stage of the study fails to meet ethical and regulatory standards. (shrink)

This chapter focuses on developing an experimental technique for inducing flow and creating instances of effortless action in the laboratory. The effort to experimentally induce flow involves two conditions which are correlated with the flow state: The firstis the idea that the challenges of a given task are well within one’s capabilities; the other involves perceived goals and immediate feedback from the given task. The chapter explores these factors along with other contextual factors, including autonomy and distractions, to experimentally induce (...) flow and demonstrate instances of effortless action in the laboratory. One of the most extensively used approaches for experimental induction of flow in the laboratory involves exploring difficulty levels of video games. (shrink)

At the heart of Levinas’s work is the apparently simple idea that through the encounter with another person, we are forced to give up our self-concern and take heed of the ethical relation between us. But, while simple on the surface, when one tries to characterize it in more detail, it can be hard to fit together the various ways in which Levinas talks about this relation and to identify precisely what he took its normative structure to be, as this (...) is described in a number of apparently different ways, that are not obviously compatible or equivalent, such as “command,” “call,” “summons,” “demand,” and so on. In this chapter, we intend to focus on these different characterizations and show what makes them different while also endeavoring to find a way in which Levinas’s conception may nonetheless be fitted together into a coherent account of the face-to-face encounter that is at the heart of his ethics. We will begin by considering the different normative terms used to characterize the encounter in that text and show how they are conceptually distinct from one another; we will then offer a way to read Levinas’s position to nonetheless show how these different normative relations can be fitted together into a stable position.

The EEG and MEG studies cited in the target article found reduced gamma band power following pseudowords in comparison with words. Pulvermüller interprets this power difference in terms of reverberating lexical cell assemblies. An alternative interpretation in terms of latency jitter in the gamma band following pseudowords is proposed that does not appeal to lexical cell assemblies.

BackgroundNarcissism viewed as a personality process rather than a stable trait explains narcissistic functioning as a tool for maintaining a positive self-view. Studying narcissism therefore needs adequate momentary measures for collecting higher frequency longitudinal data in experience sampling method studies. In this study, a shorter version of the Pathological Narcisissm Inventory is offered to measure vulnerable and grandiose narcissistic states, applicable in momentary assessment.MethodsThe measurement tool was tested in three samples. First, we assessed the factor structure and associations with other (...) contemporary measures of narcissism in a cross-sectional design on one English speaking and one Hungarian sample. Second, we conducted a five-day long experience sampling method study with a total of 15 measurement points.ResultsBased on structural equation modelling and multilevel analyses, the results suggest that the measure has adequate psychometric properties in both the within and between subject levels as well as acceptable convergent and discriminant validity.ConclusionsThe Pathological Narcissism Inventory – State Version can be a useful tool in momentary data collection enabling the examination of personality processes behind narcissistic functioning.

Although informed consent is important in clinical research, questions persist regarding when it is necessary, what it requires, and how it should be obtained. The standard view in research ethics is that the function of informed consent is to respect individual autonomy. However, consent processes are multidimensional and serve other ethical functions as well. These functions deserve particular attention when barriers to consent exist. We argue that consent serves seven ethically important and conceptually distinct functions. The first four functions pertain (...) principally to individual participants: (1) providing transparency; (2) allowing control and authorization; (3) promoting concordance with participants' values; and (4) protecting and promoting welfare interests. Three other functions are systemic or policy focused: (5) promoting trust; (6) satisfying regulatory requirements; and (7) promoting integrity in research. Reframing consent around these functions can guide approaches to consent that are context sensitive and that maximize achievable goals. (shrink)

The concept of anxiety has long held a central place in psychoanalytic theories of mind and treatment. Yet, in recent years, data from the neurosciences and from pharmacological studies have posed a compelling challenge to psychoanalytic models of anxiety. One major outcome of these studies is the realization that anxiety both organizes and disorganizes, that it can be both symptom and signal. In _Anxiety as Symptom and Signal_, editors Steven Roose and Robert Glick have brought together distinguished contributors to (...) address these different dimensions of anxiety. A section of original papers on "Anxiety as Symptom" covers evolutionary, neuroanatomical, genetic, and developmental perspectives. A complementary section on "Anxiety as Signal" focuses on the meanings and functions of anxiety in the clinical process; contributions address anxiety in its ego-psychological, intersubjective, and relational dimensions. The illuminating, readable collection will broaden clinicians' awareness of the diverse research findings that now inform our understanding of anxiety. No less importantly, it will deepen their appreciation of the richly variegated ways that anxiety can shape, and be shaped by, the clinical process. (shrink)
