The nonvisual self-touch rubber hand paradigm elicits the compelling illusion that one is touching one’s own hand even though the two hands are not in contact. In four experiments, we investigated spatial limits of distance and alignment on the nonvisual self-touch illusion and the well-known visual rubber hand illusion. Common procedures and common assessment methods were used. Subjective experience of the illusion was assessed by agreement ratings for statements on a questionnaire and time of illusion onset. The nonvisual self-touch illusion (...) was diminished though never abolished by distance and alignment manipulations, whereas the visual rubber hand illusion was more robust against these manipulations. We assessed proprioceptive drift, and implications of a double dissociation between subjective experience of the illusion and proprioceptive drift are discussed. (shrink)

"We wish this volume to be a sure companion to the study of free will, broadly construed to include action theory, moral and legal responsibility, and cohort studies feathering off into adjacent fields in the liberal arts and sciences. In addition to general coverage of the discipline, this volume attempts a more challenging and complementary accompaniment to many familiar narratives about free will. In order to map out some directions such accompaniment will take, in this introduction we anchor the thirty (...) contributions to this volume in some common history from which they arise, and attempt to indicate where future work in free will and moral responsibility will–and has already begun to–depart from that history." -Excerpt from Introduction. ... ...

This study provides a comparison of thinking style and ethical decision-making patterns between 386 U.S. students and 506 students from the People’s Republic of China enrolled in undergraduate business education in their respective countries. Contrary to our expectations, the Chinese students demonstrated a significantly greater linear thinking style compared to American students. As hypothesized, both Chinese and U.S. students possessing a balanced linear and nonlinear thinking style profile demonstrated greater ethical intent across a series of ethics vignettes. Chinese students also (...) were more likely to adopt an act utilitarian rationale, an ethical philosophy that in practice may violate government regulations or social rules to benefit one’s family instead of society for explaining their decisions across the vignettes. We conclude with a discussion of important theoretical as well as practical and potential future implications based on this comparative study. (shrink)

This commentary analyses the quantitative parameters of Reichle et al.'s model, using estimates when explicit information is not provided. The analysis highlights certain features that appear to be necessary to make the model work and ends by noting a possible problem concerning the variability associated with oculomotor programming.

Purpose Although surrogate decision-making is prevalent in intensive care units and concerns with decision quality are well documented, little is known about how clinicians help family members understand the surrogate role. We investigated whether and how clinicians provide normative guidance to families regarding how to function as a surrogate. Subjects and methods We audiorecorded and transcribed 73 ICU family conferences in which clinicians anticipated discussing goals of care for incapacitated patients at high risk of death. We developed and applied a (...) coding framework to identify normative statements by clinicians regarding what considerations should guide surrogates’ decisions, including whether clinicians explained one or more of Buchanan and Brock’s three standard principles of SDM to family members. Results Clinicians made at least one statement about how to perform the surrogate role in 24 conferences ). We observed three general types of normative guidance provided to surrogates, with some conferences containing more than one type of guidance: counselling about one or more standard principles of SDM ; counselling surrogates to make decisions centred on the patient as a person, without specifying how to accomplish that ; and counselling surrogates to make decisions based on the family’s values. Conclusions Clinicians did not provide normative guidance about the surrogate role in two-thirds of family conferences for incapacitated patients at high risk for death. When they did, clinicians’ guidance was often incomplete and sometimes conflicted with standard principles of SDM. Future work is needed to understand whether providing explicit guidance on how to perform the surrogate role improves decision-making or mitigates surrogates’ psychological distress. (shrink)

We examine the ethical, social, and regulatory barriers that may hinder research on therapeutic potential of certain controversial controlled substances like marijuana, heroin, or ketamine. Hazards for individuals and society and potential adverse effects on communities may be good reasons for limiting access and justify careful monitoring of these substances. Overly strict regulations, fear of legal consequences, stigma associated with abuse and populations using illicit drugs, and lack of funding may, however, limit research on their considerable therapeutic potential. We review (...) the surprisingly sparse literature and address the particular ethical concerns pertinent to research with illicit and addictive substances, such as undue inducement, informed consent, therapeutic misconception, and risk to participants, researchers, and institutions. We consider the perspectives of key research stakeholders and explore whether they may be infected with bias. We conclude by proposing an empirical research agenda to provide an evidentiary basis for ethical reasoning. (shrink)

The concept of free will is fraught with controversy, as readers of this volume likely know. Philosophers disagree about what free will is, whether we have it, what mitigates or destroys it, and what it's good for. Indeed, philosophers even disagree about how to fix the referent of the term 'free will' for purposes of describing and exploring these disagreements. What one person considers a reasonably neutral working definition of 'free will' is often considered question-begging or otherwise misguided by another. (...) Such disputes make it difficult to summarize the problem of free will, roughly the debate over the nature and existence of free will, in a clear and uncontentious way. In generic terms, however, the two basic solutions to the problem of free will are free-willism, the view that we have free will, and free-will denialism, i.e. the view that we do not have free will. As stated here, neither denialism nor free-willism constitutes a complete solution to the problem of free will; to be complete, a proposed solution must also tell us a convincing story about what free will is and that, as it turns out, is a very difficult task indeed. One historically popular way of approaching the problem of free will is to ask about the relationship between free will and determinism: "Does free will stand in relation R to determinism: yes or no?" This is just a template for a question, of course. To transform this template-question into a substantive question with a clear meaning, we need to flesh out the template's free-will relatum, its determinism relatum, and give a precise value to relation R. There is, however, no uncontroversial way to do this. In addition to the standard difficulties raised by fixing the referent of 'free will', philosophers hold radically different views about what is-or should be-meant by 'determinism', Shabo ), and they identify relations which are as substantively different as correlation and causation when characterizing relation R. In practical terms, then, it may be best to think of the problem of determinism as a loose collection of disagreements about how to best spell out and answer the template-question, and how asking and answering such questions would help us to solve the problem of free will.

Particular visions of urban development are often codified in multi-year resource management policies. These policies, and the negotiations leading to them, are based in specific problem frames and narratives with long legacies. As conditions change and knowledge improves, there is often a need to revisit how problems, opportunities, and development pathways were defined historically, and to consider the viability of alternative pathways for development. In this article, we examine the case of agriculture near Metropolitan Phoenix, in the Central Arizona region, (...) to highlight how frames and narratives embedded in policy can reinforce particular development pathways, even as information, conditions, and values evolve. Using expert interviews and secondary data, we document alternative frames and narratives that may offer different pathways for development and sustainability in the region. By highlighting alternative narratives, we demonstrate the uncertainties and limitations associated with all narratives about development pathways, and explore the possibilities that narrative shifts can alter future outcomes.

This volume provides a philosophical introduction to and analysis of the study of metaphor. By proceeding from the concrete analysis of complex metaphors, White is able to identify a range of features which are incompatible with standard accounts of the way words function in metaphor.

The thymus is a unique primary lymphoid organ that supports the production of self‐tolerant T‐cells essential for adaptive immunity. Intrathymic microenvironments are microanatomically compartmentalised, forming defined cortical, and medullary regions each differentially supporting critical aspects of thymus‐dependent T‐cell maturation. Importantly, the specific functional properties of thymic cortical and medullary compartments are defined by highly specialised thymic epithelial cells (TEC). For example, in the medulla heterogenous medullary TEC (mTEC) contribute to the enforcement of central tolerance by supporting deletion of autoreactive T‐cell (...) clones, thereby counterbalancing the potential for random T‐cell receptor generation to contribute to autoimmune disease. Recent advances have further shed light on the pathways and mechanisms that control heterogeneous mTEC development and how differential mTEC functionality contributes to control self‐tolerant T‐cell development. Here we discuss recent findings in relation to mTEC development and highlight examples of how mTEC diversity contribute to thymus medulla function. (shrink)

Objective: Even when critically ill patients are almost certain to die from their illnesses, there is generally an element of prognostic uncertainty. Little is known about how physicians handle this uncertainty in conversations with surrogate decision makers. We sought to evaluate whether and how physicians discuss prognostic uncertainty with surrogate decision makers of patients who are highly likely, but not certain, to die. Design: We audiotaped and transcribed discussions between clinicians and surrogate decision makers at two major California teaching hospitals (...) from 2006 through 2008. Physicians completed a questionnaire addressing their prognostic estimates for patients' survival to hospital discharge. Participants: We included physicians and surrogates of 12 incapacitated, critically ill patients. Measurements: We analyzed transcripts of discussions in which physicians' estimates of patients' chances of hospital survival were 1% to 5%; we coded whether physicians disclosed the prognostic uncertainty and, if so, how they conveyed that death was highly likely but not certain. Results: Physicians' estimates of short-term survival were 1% to 5% for 12 of the 70 patients enrolled in the original study. In 8 of 12 cases, physicians conveyed prognostic uncertainty by using probabilistic language or by an explicit mention of uncertainty. In four cases, physicians made at least one statement that either implied or was ambiguous about whether death was certain. Conclusion: We observed variability in how physicians handle prognostic uncertainty in their discussions with surrogates of patients who are highly likely, but not certain, to die, including some circumstances in which physicians stated or implied that death was certain.

On September 1, 2023, Texas made important revisions to it its decades‐old statute granting legal safe harbor immunity to physicians who withhold or withdraw life‐sustaining treatment over the objection of critically ill patients’ surrogate decision‐makers. However, lawmakers left untouched glaring flaws in a key safeguard for patients—the transfer option. The transfer option is ethically important because, when no hospital is willing to accept the patient in transfer, that fact is taken as strong evidence that the surrogates’ treatment requests fall outside (...) accepted medical practice. But there are serious shortcomings in how the transfer option is carried out in Texas and many other states, which undermines the ethical usefulness of the process. We identify these shortcomings and recommend revisions to state statutes and professional guidelines to overcome them. (shrink)

We construct a class of relations on computable structures whose degree spectra form natural classes of degrees. Given any computable ordinal and reducibility r stronger than or equal to m-reducibility, we show how to construct a structure with an intrinsically invariant relation whose degree spectrum consists of all nontrivial r-degrees. We extend this construction to show that can be replaced by either or.

Coronavirus disease 2019 can lead to respiratory failure. Some patients require extracorporeal membrane oxygenation support. During the current pandemic, health care resources in some cities have been overwhelmed, and doctors have faced complex decisions about resource allocation. We present a case in which a pediatric hospital caring for both children and adults seeks to establish guidelines for the use of extracorporeal membrane oxygenation if there are not enough resources to treat every patient. Experts in critical care, end-of-life care, bioethics, and (...) health policy discuss if age should guide rationing decisions. (shrink)

“Informed consent” is a legal instrument that allows individuals to define their own interests and to protect their bodily privacy. In current medical practice, patients who have consented to surgery are considered to have implied consent to anaesthesia, even though anaesthesia is associated with its own particular set of risks and consequences that are quite separate from those associated with surgery. In addition, anaesthetists often perform interventions that are the only medical treatment received by a patient. Anaesthetists, therefore, should always (...) obtain separate consent for anaesthesia, and should regard the process of consent as a stimulus for active, fluid reciprocal discussion with patients about treatment options.

A policy of “preventive detention” has recently been debated in the British Parliament. Alarmed by the high-profile criminal activities of people suspected of having dangerous severe personality disorder , the government have made clear their intention to “indeterminately but reviewably detain” people with DSPD, after diagnosis by forensic psychiatrists, even if the individuals are yet to commit an offence. Such a policy may improve the safety of the public, but has obvious implications for civil liberties. This essay criticises the morality (...) of the government's intention and rejects the notion that the medical profession could ethically collude with such a policy. (shrink)

The increasing effort, both lay and academic, to encourage a transition from an “I-It” to an “I-Thou” relation to nature is located within a typology of ways of “knowing nature.” This typology provides the context for a particular understanding of human conversation which sees the relation as a cyclical process of “immersion” and “realization” from which a model of the dialectic between “I-It” and “I-Thou” relations to nature can be developed. This model can be used to identify practical measures that (...) can be taken as first steps toward a balance between these relations, both in general and in the context of science-oriented nature conservation organizations such as English Nature in Britain.

The replicability and importance of the correlation between cognitive style and religious belief have been debated. Moreover, the literature has not examined distinct psychological accounts of this relationship. We tested the replicability of the correlation (N = 5284; students and broader samples of Canadians, Americans, and Indians); while testing three accounts of how cognitive style comes to be related to belief in God, karma, witchcraft, and to the belief that religion is necessary for morality. The first, the dual process model, (...) posits that analytical thinking is recruited in overriding intuitions related to supernatural beliefs. The second, the expressive rationality model, posits that analytical thinking is recruited in supporting already-held beliefs in an identity-protective manner. And the third, the counter-normativity rationality model, posits that analytical thinking is recruited to question beliefs supported by prevailing cultural norms. In Study 2, we tested the replicability of our results in a re-analysis of published data. The association between analytic thinking style and beliefs was replicated. We conclude that whereas the counter-normativity rationality model was contradicted by the data, both the dual process and expressive rationality models received varying degrees of empirical support, but neither model fully accounted for all the patterns in the data.

Inattentional blindness studies have shown that an unexpected object may go unnoticed if it does not share the property specified in the task instructions. Our aim was to demonstrate that observers develop an attentional set for a property not specified in the task instructions if it allows easier performance of the primary task. Three experiments were conducted using a dynamic selective-looking paradigm. Stimuli comprised four black squares and four white diamonds, so that shape and colour varied together. Task instructions (...) specified shape but observers developed an attentional set for colour, because we made the black–white discrimination easier than the square–diamond discrimination. None of the observers instructed to count bounces by squares reported an unexpected white square, whereas two-thirds of observers instructed to count bounces by diamonds did report the white square. When attentional set departs from task instructions, you may fail to see what you were told to look for. (shrink)

The attitudes of patients' to consent have changed over the years, but there has been little systematic study of the attitudes of anaesthetists and surgeons in this process. We aimed to describe observations made on the attitudes of medical professionals working in the UK to issues surrounding informed consent.

We propose six guideposts that states and hospitals should follow to respect disability rights when designing policies for the allocation of scarce, lifesaving medical treatments. Four relate to criteria for decisions. First, do not use categorical exclusions, especially ones based on disability or diagnosis. Second, do not use perceived quality of life. Third, use hospital survival and near-term prognosis (e.g., death expected within a few years despite treatment) but not long-term life expectancy. Fourth, when patients who use ventilators in their (...) daily lives (e.g., home ventilation) present to acute care hospitals, their personal ventilators should not be reallocated to other patients. Fifth, designate triage officers to assess patients individually on the basis of objective medical evidence, not stereotypes or assumptions. Sixth, include disability rights advocates in policy development and dissemination. (shrink)
