Sustained attention, a key cognitive skill that improves during childhood and adolescence, tends to be worse in some emotional and behavioural disorders. Sustained attention is typically studied in non-affective task contexts; here, we used a novel task to index performance in affective versus neutral contexts across adolescence (N = 465; ages 11–18). We asked whether: (i) performance would be worse in negative versus neutral task contexts; (ii) performance would improve with age; (iii) affective interference would be greater in younger adolescents; (...) (iv) adolescents at risk for depression and higher in anxiety would show overall worse performance; and (v) would show differential performance in negative contexts. Results indicated that participants performed more poorly in negative contexts and showed age-related performance improvements. Those at risk of depression performed more poorly than those at lower risk. However, there was no difference between groups as a result of affective context. For anxiety there was no difference in performance as a function of severity. However, those with higher anxiety showed less variance in their reaction times to negative stimuli than those with lower anxiety. One interpretation is that moderate levels of emotional arousal associated with anxiety make individuals less susceptible to the distracting effects of negative stimuli. (shrink)

We discuss our surgical philosophy concerning the subtle interplay between the size of the surgical margin taken and the resultant morbidity from ablative oncological. procedures, which is ever more evident in the treatment of head and neck malignancy. The extent of tissue resection is determined by the "trade off" between cancer control and the perioperative, functional and aesthetic morbidity and mortality of the surgery. We also discuss our dilemmas concerning recent minimally invasive endoscopic microsurgical. techniques for the trans-oral laser removal. (...) or co-ablation of aero-digestive tract tumours, which result in a minimal. surgical margin of oncological clearance. By a process of inductive argument as to the nature of the surgical margin, we consider whether the risks of taking a lesser margin with adjuvant therapy is justified by the attendant gain in reduced surgical morbidity and the possible costs in tumour control.

This introductory textbook presents Christian philosophical and theological approaches to ethics. Combining their expertise in philosophy and theology, the authors explain the beliefs, values, and practices of various Christian ethical viewpoints, addressing biblical teachings as well as traditional ethical theories that contribute to informed moral decision-making. Each chapter begins with Words to Watch and includes a relevant case study on a vexing ethical issue, such as caring for the environment, human sexuality, abortion, capital punishment, war, and euthanasia. End-of-chapter reflection questions, (...) illustrations, and additional information tables are also included. (shrink)

Understanding cooperation and punishment in small-scale societies is crucial for explaining the origins of human cooperation. We studied warfare among the Turkana, a politically uncentralized, egalitarian, nomadic pastoral society in East Africa. Based on a representative sample of 88 recent raids, we show that the Turkana sustain costly cooperation in combat at a remarkably large scale, at least in part, through punishment of free-riders. Raiding parties comprised several hundred warriors and participants are not kin or day-to-day interactants. Warriors incur substantial (...) risk of death and produce collective benefits. Cowardice and desertions occur. (shrink)

Despite a decade of federal regulation and debate over the appropriateness of financial ties in research and their management, little is known about the actual decision-making processes of university conflict of interest (COI) committees. This paper analyzes in detail the discussions and decisions of three COI committees at three public universities in California. University committee members struggle to understand complex financial relationships and reconcile institutional, state, and federal policies and at the same time work to protect the integrity of the (...) scientific process, the autonomy and intellectual freedom of their faculty colleagues and students, and the financial interests of the university.

Much existing literature in anthropology suggests that teaching is rare in non-Western societies, and that cultural transmission is mostly vertical (parent-to-offspring). However, applications of evolutionary theory to humans predict both teaching and non-vertical transmission of culturally learned skills, behaviors, and knowledge should be common cross-culturally. Here, we review this body of theory to derive predictions about when teaching and non-vertical transmission should be adaptive, and thus more likely to be observed empirically. Using three interviews conducted with rural Fijian populations, we (...) find that parents are more likely to teach than are other kin types, high-skill and highly valued domains are more likely to be taught, and oblique transmission is associated with high-skill domains, which are learned later in life. Finally, we conclude that the apparent conflict between theory and empirical evidence is due to a mismatch of theoretical hypotheses and empirical claims across disciplines, and we reconcile theory with the existing literature in light of our results.

Much human adaptation depends on the gradual accumulation of culturally transmitted knowledge and technology. Recent models of this process predict that large, well-connected populations will have more diverse and complex tool kits than small, isolated populations. While several examples of the loss of technology in small populations are consistent with this prediction, it found no support in two systematic quantitative tests. Both studies were based on data from continental populations in which contact rates were not available, and therefore these studies (...) do not provide a test of the models. Here, we show that in Oceania, around the time of early European contact, islands with small populations had less complicated marine foraging technology. This finding suggests that explanations of existing cultural variation based on optimality models alone are incomplete because demography plays an important role in generating cumulative cultural adaptation. It also indicates that hominin populations with similar cognitive abilities may leave very different archaeological records, a conclusion that has important implications for our understanding of the origin of anatomically modern humans and their evolved psychology.

Richard Holton has argued that the traditional account of intentions—which only posits the existence of all-out intentions—is inadequate because it fails to accommodate dual-plan cases; ones in which it is rationally permissible for an agent to adopt two competing plans to bring about the same end. Since the consistency norms governing all-out intentions prohibit the adoption of competing intentions, we can only preserve the idea that the agent in a dual-plan case is not being irrational if we attribute to them (...) a pair of partial intentions. I argue that, contrary to initial appearances, (i) Holton has yet to offer us an actual account of partial intentions, and (ii) that the traditional account of intentions already has the resources necessary to accommodate dual-plan cases.

This book is the result of a three-year study undertaken by a multidisciplinary working party of the Institute of Medical Ethic (UK). The group was chaired by a moral theologian, and its members included biological and ethological scientists, toxicologists, physicians, veterinary surgeons, an expert in alternatives to animal use, officers of animal welfare organizations, a Home Office Inspector, philosophers, and a lawyer. Coming from these different backgrounds, and holding a diversity of moral views, the members produced the agreed report as (...) a result of detailed and rigorous discussions. The book sets out facts about animal experiments and about animal abilities to experience pain, distress and anxiety. There is a detailed examination of the moral claims related to the benefits likely to accrue from animal research, and of strategies for weighing these benefits against the harm caused to animals, in order to decide whether particular research projects ought or ought not to proceed. This leads to consideration of the statutory and non-statutory controls which safeguard standards in such research. The final section explores a variety of philosophical arguments about the use of animals in research, and offers a philosophical justification for the Working Party's more practical conclusions. Written in clear, nontechnical language, this book is accessible to lay people as well as to scientists. It is the first such document to emerge from a meeting of people with such widely differing views on this highly controversial subject, and represents a major contribution towards informing and raising the quality of contemporary debate. The book is unique in drawing together material and ideas never before found in one volume. It will interest a broad spectrum of readers, from ethicists and animal rights advocates to scientific researchers and laboratory administrators, along with general readers concerned about this compelling issue.

Background. The concept of empathy in students has gained significant attention in medical education. Whether implementing formal educational interventions to promote long-term and effective empathy levels leads to sustained increased empathy levels in students, is however less clear. Objectives. The study aimed to evaluate the trajectory of medical students’ self-perceived empathy levels during their 6-year MB ChB degree. Methods. A longitudinal, prospective study was conducted over 4 years. A cohort of 292 medical students was invited to participate. Participants completed the (...) Jefferson Scale of Empathy for Students (JSE-S) at three intervals during their studies. The students attended two workshops related to empathic patient interactions during this time. The JSE-S mean score by age and gender was compared, making use of a linear regression model. Results. A total of 119 students completed the study. Students’ total empathy levels were similar during the first and the last measuring point (110), but there was a significant rise in the intermediate measuring point (113.3). When the male and female cohorts’ scores were interpreted separately, both genders demonstrated a similar pattern to the total score, although females’ JSE-S scores were higher than the males. Conclusion. The results of the study confirm that educational interventions can increase students’ self-perceived empathy levels; however, we suggest that students require reinforcement and multiple opportunities to practise and observe empathic communication with patients to sustain high levels of empathy. Follow-up sessions to specifically target the promotion of empathy should be implemented; otherwise the long-term effect of educational interventions might be limited. (shrink)

Jesus instructs us to “love,” “pray for,” and “do good” to enemies, going so far as to make this response to enemies the criterion for being considered “children of your Father in heaven”. Jesus based this instruction on the character of the Father, not on the character of our enemies, which means his instruction allows for no exceptions. In this essay I flesh out the implications of this for a Christian response to terrorism, arguing that this response should look radically (...) different from that of just war theorists. (shrink)

Interpreters of Aquinas’s theory of natural law have occasionally argued that the theory has no need for God. Some, such as Anthony Lisska, wish to avoid an interpretation that construes the theory as an instance of theological definism. Instead Lisska sees Aquinas’s ontology of natural kinds as central to the theory. In his zeal to eliminate God from Aquinas’s theory of natural law, Lisska has overlooked two important features of the theory. First, Aquinas states that the desire for God is (...) a primary precept of the natural law and thus constitutes a critical aspect of his ontology. Secondly, Aquinas’s theory of natural law must be seen in the larger context of his theory of participation since he says, “The natural law is the rational creature’s participation in the eternal law.”.

The Edinburgh Medical Group Research Project is unique in Britain. Part of its function is to experiment with teaching medical ethics both inside and outside of the Medical School. The papers which follow have been written by two full-time reseach fellows working with the Project and two of the professional advisers, one nursing and one medical. Together they give a picture of the wide scope of exerimental teaching taking place in Edinburgh and present some preliminary results from these experiments.

Very often when the vast majority of experts agree on some scientific issue, laypeople nonetheless regularly consume articles, videos, lectures, etc., the principal claims of which are inconsistent with the expert consensus. Moreover, it is standardly assumed that it is entirely appropriate, and perhaps even obligatory, for laypeople to consume such anti-consensus material. I maintain that this standard assumption gets things backwards. Each of us is particularly vulnerable to false claims when we are not experts on some topic – such (...) falsehoods have systematic negative impacts on our doxastic attitudes that we can neither prevent nor correct. So, when there is clear expert consensus on a given scientific issue, while it is permissible for experts to consume anti-consensus material, laypeople have an epistemic obligation to avoid such material. This argument has important consequences for philosophical discussions of our epistemic obligations to perform or omit belief-influencing actions. Such discussions typically abstract away from the important differences between experts and laypeople. Accordingly, we should reject this typical practice as problematic, and insist instead that laypeople and experts have fundamentally different epistemic obligations. (shrink)

According to an influential variety of the representational view of perceptual experience—the singular content view—the contents of perceptual experiences include singular propositions partly composed of the particular physical object a given experience is about or of. The singular content view faces well-known difficulties accommodating hallucinations; I maintain that there is also an analogue of Frege's puzzle that poses a significant problem for this view. In fact, I believe that this puzzle presents difficulties for the theory that are unique to perception (...) in that strategies that have been developed to respond to Frege's puzzle in the case of belief cannot be employed successfully in the case of perception. Ultimately, I maintain that this perceptual analogue of Frege's puzzle provides a compelling reason to reject the singular content view of perceptual experience. (shrink)

All representationalists maintain that there is a necessary connection between an experience’s phenomenal character and intentional content; but there is a disagreement amongst representationalists regarding the nature of those intentional contents that are necessarily connected to phenomenal character. Russellian representationalists maintain that the relevant contents are composed of objects and/or properties, while Fregean representationalists maintain that the relevant contents are composed of modes of presentation of objects and properties. According to Fregean representationalists such as David Chalmers and Brad Thompson, the (...) Fregean variety of the view is preferable to the Russellian variety because the former can accommodate purported counterexamples involving spectrum inversion without illusion and colour constancy while the latter cannot. I maintain that colour constancy poses a special problem for the Fregean theory in that the features of the theory that enable it handle spectrum inversion without illusion cannot be extended to handle colour constancy. I consider the two most plausible proposals regarding how the Fregean view might be developed in order to handle colour constancy—one of which has recently been defended by Thompson —and argue that neither is adequate. I conclude that Fregean representationalism is no more able to accommodate colour constancy than is Russellian representationalism and, as such, ought to be rejected. (shrink)

One of the key learning objectives in any health professional course is to develop ethical and judicious practice. Therefore, it is important to address how medical and pharmacy students respond to, and deal with, ethical dilemmas in their clinical environments. In this paper, we examined how students communicated their resolution of ethical dilemmas and the alignment between these communications and the four principles developed by Beauchamp and Childress. Three hundred and fifty-seven pharmacy and medical students (overall response rate=63%) completed a (...) questionnaire containing four clinical case scenarios with an ethical dilemma. Data were analysed using multiple methods. The findings revealed that 73% of the qualitative responses could be exclusively coded to one of the ‘four principles’ determined by the Beauchamp and Childress' framework. Additionally, 14% of responses overlapped between the four principles (multiple codes) and 13% of responses could not be coded using the framework. The subsequent subgroup analysis revealed different response patterns depending on the case being reviewed. The findings showed that when students are faced with challenging ethical dilemmas their responses can be aligned with the Beauchamp and Childress framework, although more contentious dilemmas involving issues of law are less easily categorised. The differences between year and discipline groups show students are developing ethical frames of reference that may be linked with their teaching environments and their levels of understanding. Analysis of these response patterns provides insight into the way students will likely respond in ‘real’ settings and this information may help educators prepare students for these clinical ethical dilemmas.

Largely thanks to Mill’s influence, the suggestion that the state ought to restrict the distribution of misinformation will strike most philosophers as implausible. Two of Mill’s influential assumptions are particularly relevant here: first, that free speech debates should focus on moral considerations such as the harm that certain forms of expression might cause; second, that false information causes minimal harm due to the fact that human beings are psychologically well equipped to distinguish truth and falsehood. However, in addition to our (...) moral obligations, we also have a distinct set of epistemic obligations—and even when a false belief doesn’t harm anyone, it constitutes an epistemically bad outcome. Moreover, Mill was profoundly mistaken about human psychology: human beings are vulnerable to the influence of a wide variety of false claims via a wide variety of psychological mechanisms. Consequently, there is a purely epistemic justification for restricting the distribution of misinformation: because each of us has an individual epistemic obligation to avoid unnecessary exposure to misinformation, and because avoiding such exposure is simply too difficult when acting alone, we all have a shared epistemic obligation to establish laws or regulations restricting the widespread distribution of misinformation.

BackgroundFindings suggest pandemic control measures have modified maternal health practices, compromising the quality of care provided to new and expectant mothers and interfering with their birthing experiences. For this reason, this study explored the lived experiences of post-partum Victorian mothers during the pandemic as well as the potential influence of control measures over their perceptions regarding the health system.MethodsThis study used a qualitative approach. Recruitment was conducted between May and June 2021, using both the Australian Breastfeeding Association’s social media pages (...) and snowball recruitment. Interviews were semi-structured using open-ended questions relating to key themes. Seven Victorian post-partum mothers were identified and their transcripts analysed using Interpretative Phenomenological Analysis.ResultsMothers described how unexpected changes to maternal care exacerbated feelings of uncertainty regarding pregnancy and birth. Mothers also differentiated between impacts by the health system and the role healthcare professionals played in moderating these effects. Whilst visitor restrictions provided some benefit, restrictions to familial and social support left many of the mothers feeling alone during their pregnancy and interfered with their immediate post-partum experience.ConclusionThis study illustrates the importance of evidence-based practice in maternal care and provides insights for both health professionals and policy analysts in developing new or modifying existing guidelines that better balance the needs of expectant and post-partum mothers with pandemic control measures.

Biology and the social sciences share an interest in phylogeny. Biologists know that living species are descended from past species, and use the pattern of similarities among living species to reconstruct the history of phylogenetic branching. Social scientists know that the beliefs, values, practices, and artifacts that characterize contemporary societies are descended from past societies, and some social science disciplines, linguistics and cross cultural anthropology for example, have made use of observed similarities to reconstruct cultural histories. Darwin appreciated that his (...) theory of descent with modification had many similarities of pattern and process to the already well developed field of historical linguistics. In many other areas of social science, however, phylogenetic reconstruction has not played a central role. (shrink)

In this article I offer a naturalistic defence of semantic externalism. I argue against the following: (1) arguments for externalism rest mainly on conceptual analysis; (2) the community conceptual norms relevant to individuation of propositional attitudes are quasi-analytic; (3) externalism raises serious questions about knowledge of propositional attitudes; and (4) externalism might be OK for “folk psychology” but not for cognitive science. The naturalist alternatives are as follows. (1) Community norms are not anything like a priori; sometimes they are incoherent. (...) (2) Often propositional attitudes lack determinate content: we do not know the content of thoughts or sentences because there is no fully definite content to be known. (3) Often achieving determinate content is a major socially mediated cognitive achievement that depends on just the factors of social and environmental embedding posited as individuative by externalists, so (4) externalism explains how people can, sometimes, come to have, and to know, determinate attitude contents. (5) Reference and content, for both thought and language, are determined by complex and messy dialectical relations involving many such environmental and social factors; consequently, determinate reference, truth-conditions, etc., are somewhat uncommon outcomes. (6) The basic semantic relation is (typically imperfect) socially mediated accommodation between perceptual, cognitive, linguistic, classificatory and inferential dispositions and relevant causal structures in the environment. (7) This accommodation explains how concepts, language, taxonomies, etc., contribute to individuals' rational inductive, explanatory and practical achievements. (8) So externally individuated propositional attitudes are required for cognitive science explanations of individual human rationality and its inductive and explanatory achievements. “Individual rationality ain't (entirely) in the individual head.”.

Virtually every aspect of the current philosophical discussion of self-deception is a matter of controversy including its definition and paradigmatic cases. We may say generally, however, that self-deception is the acquisition and maintenance of a belief (or, at least, the avowal of that belief) in the face of strong evidence to the contrary motivated by desires or emotions favoring the acquisition and retention of that belief. Beyond this, philosophers divide over whether this action is intentional or not, whether self-deceivers recognize (...) the belief being acquired is unwarranted on the available evidence, whether self-deceivers are morally responsible for their self-deception, and whether self-deception is morally problematic (and if it is in what ways and under what circumstances). The discussion of self-deception and its associated puzzles gives us insight into the ways in which motivation affects belief acquisition and retention. And yet insofar as self-deception represents an obstacle to self-knowledge, which has potentially serious moral implications, self-deception is more than an interesting philosophical puzzle. It is a problem of particular concern for moral development, since self-deception can make us strangers to ourselves and blind to our own moral failings. (shrink)

Can there be a duty to forgive those who have wronged us? According to a popular view amongst philosophers working on forgiveness the answer is no. Forgiveness, it is claimed, is always elective. This view is rejected by Gamlund (2010a; 2010b) who argues that duties to forgive do exist and then provides conditions that are relevant to determining whether forgiveness is obligatory or supererogatory. In this paper I will argue that the conditions that Gamlund provides do not provide a plausible (...) account of the connection between forgiveness and duty. The problems I will raise against Gamlund’s view is a problem that faces any moral view that makes room for supererogation. I will then investigate whether the existing solutions to this problem provide a more plausible account of the connection between forgiveness and obligation. I will argue that the two most prominent solutions, The Favouring Reasons View and The Sacrifice View, produce implausible results when applied to the case of forgiveness. However, an alternative view, The Freedom View, can provide plausible results when applied to the case of forgiveness. This gives us defeasible reason to favour this as a general solution to The Problem of the Good Ought Tie-Up. (shrink)

What role should a motivation to do the right thing, read de dicto, play in the life of a virtuous agent? According to a prominent argument from Michael Smith, those who are only motivated by such a desire are moral fetishists. Since Smith’s argument, a number of philosophers have examined what role this desire would play in the life of the morally virtuous agent. My primary aim in this paper is an historical one. I will show that much of this (...) discussion can be found in Adam Smith’s The Theory of the Moral Sentiments (1764), published over two hundred years before Michael Smith’s The Moral Problem. I will then argue that there is an important insight to be found in Adam Smith’s book that is missing from the contemporary discussion. According to Adam Smith, while a de dicto desire to do the right thing can play an important role in the life of a virtuous agent, the person who is only ever motivated by this desire will often be epistemically disadvantaged compared to the person who possesses the appropriate sentiments. I will argue that Adam Smith’s claim is plausible given his own view of the moral sentiments as providing the foundation of morality. In addition, there is good reason to accept Smith’s claim even for those who do not accept his view of the foundational role of the moral sentiments. (shrink)

Historically, entities with a vested interest in a product that critics have suggested is harmful have consistently used research to back their claims that the product is safe. Prominent examples are: tobacco, lead, bisphenol A, and atrazine. Research literature indicates that about 80–90% of studies with industry affiliation found no harm from the product, while only about 10–20% of studies without industry affiliation found no harm. In parallel to other historical debates, recent studies examining a possible relationship between mercury exposure (...) and autism spectrum disorder show a similar dichotomy. Studies sponsored and supported by industry or entities with an apparent conflict of interest have most often shown no evidence of harm or no “consistent” evidence of harm, while studies without such affiliations report positive evidence of a Hg/autism association. The potentially causal relationship between Hg exposure and ASD differs from other toxic products since there is a broad coalition of entities for whom a conflict of interest arises. These include influential governmental public health entities, the pharmaceutical industry, and even the coal burning industry. This review includes a systematic literature search of original studies on the potential relationship between Hg and ASD from 1999 to August 2015, finding that of the studies with public health and/or industry affiliation, 86% reported no relationship between Hg and ASD. However, among studies without public health and/or industry affiliation, only 21% find no relationship between Hg and ASD. The discrepancy in these results suggests a bias indicative of a conflict of interest. (shrink)

The philosophical difficulties presented by self-deception are vexed and multifaceted. One such difficulty is what I call the ‘doxastic problem’ of self-deception. Solving the doxastic problem involves determining whether someone in a state of self-deception that ∼p both believes that p and believes that ∼p, simply holds one or the other belief, or, as I will argue, holds neither. This final option, which has been almost entirely overlooked to-date, is what I call ‘ nondoxasticism ’ about self-deception. In this article, (...) I present a negative case for nondoxasticism according to which, in the paradigm case of self-deception, there is no explanatory need to attribute the self-deceived person either their undesired belief that p, or their desired belief that ∼p. Folk psychology is replete with concepts other than belief, and if we bear this in mind, it becomes clear that the explanatory roles for which the self-deceived person's purported beliefs have traditionally been enlisted can be comfortably filled without recourse to belief.

The reports of individuals who have had their vision restored after a long period of blindness suggest that, immediately after regaining their vision, such individuals are not able to recognize shapes by vision alone. It is often assumed that the empirical literature on sight restoration tells us something important about the relationship between visual and tactile representations of shape. However, I maintain that, immediately after having their sight restored, at least some newly sighted individuals undergo visual experiences that instantiate basic (...) shape phenomenology but which do not present (that is, neither represent nor involve acquaintance with) the corresponding shape properties. Consequently, the empirical literature on sight restoration tells us something important about the role that perceptual phenomenology plays in our perceptual awareness of an object’s properties—it tells us that the properties presented by perceptual experiences are not determined by or “built into” perceptual phenomenology. In addition, I maintain that the evidence concerning sight restoration suggests an alternative theory concerning the role that sensory phenomenology plays in our perceptual awareness of an object’s properties. Specifically, it suggests that, while not inherently representational, sensory phenomenal properties can serve as vehicles for the representation of an object’s properties. (shrink)
