A distorted representation of one's own body is a diagnostic criterion and core psychopathology of both anorexia nervosa (AN) and bulimia nervosa (BN). Despite recent technical advances in research, it is still unknown whether this body image disturbance is characterized by body dissatisfaction and a low ideal weight and/or includes a distorted perception or processing of body size. In this article, we provide an update and meta-analysis of 42 articles summarizing measures and results for body size estimation (BSE) from 926 (...) individuals with AN, 536 individuals with BN and 1920 controls. We replicate findings that individuals with AN and BN overestimate their body size as compared to controls (ES= 0.63). Our meta-regression shows that metric methods (BSE by direct or indirect spatial measures) yield larger effect sizes than depictive methods (BSE by evaluating distorted pictures), and that effect sizes are larger for patients with BN than for patients with AN. To interpret these results, we suggest a revised theoretical framework for BSE that accounts for differences between depictive and metric BSE methods regarding the underlying body representations (conceptual vs. perceptual, implicit vs. explicit). We also discuss clinical implications and argue for the importance of multimethod approaches to investigate body image disturbance. (shrink)

Klein, Nguyen, & Zhang (in press) argued that the evolutionary transition from respondent to agent during the Cambrian Explosion would be a promising vantage point from which to gain insight into the evolution of organic sentience. They focused on how increased competition for resources -- in consequence of the proliferation of new, neurally sophisticated life-forms -- made awareness of the external world (in the service of agentic acts) an adaptive priority. The explanatory scope of Klein et al (in (...) press) was limited to consideration of the conscious apprehension of externally sourced content – i.e., content delivered from the sensory registration of objects occupying phenomenal space. But consciousness – at least for humans -- takes its objects from internal as well as external sources. In the present article we extend their analysis to the question of how internally sourced content (i.e., mental states) became the object of conscious apprehension. (shrink)

Corporate social responsibility has been intensively discussed in business ethics literature, whereas the social responsibility of private consumers appears to be less researched. However, there is also a growing interest from business ethicists and other scholars in the field of consumer social responsibility. Nevertheless, previous discussions of ConSR reveal the need for a viable conceptual basis for understanding the social responsibility of consumers in an increasingly globalized market economy. Moreover, evolutionary aspects of human morality seem to have been neglected despite (...) the fact that private consumers are undoubtedly human beings. In addition to that, empirical studies suggest that many consumers believe themselves to be responsible but do not act according to their alleged values or attitudes. This raises the question of what deters them from doing so. Therefore, the contribution of this conceptual paper is threefold: we conceptualize ConSR in terms of a combination of a Max Weber-inspired approach with the social connection approach to shared responsibility proposed by Iris Marion Young; shed light on the previously neglected implications of an evolutionarily induced bounded morality for ConSR, and identify potential obstacles to socially responsible consumption, particularly against the backdrop of shared social responsibility and bounded morality. In this latter respect, the paper focuses specifically on the obstacles of low moral intensity, moral stupefaction, informational complexity, and the lack of perceived consumer effectiveness. In sum, the paper advances knowledge in the field of ConSR by using a transdisciplinary, literature-based approach. (shrink)

Unlike the overall framework of Ernest Nagel's work on reduction, his theory of intertheoretic connection still has life in it. It handles aptly cases where reduction requires complex representation of a target domain. Abandoning his formulation as too liberal was a mistake. Arguments that it is too liberal at best touch only Nagel's deductivist theory of explanation, not his condition of connectability. Taking this condition seriously gives a powerful view of reduction, but one which requires us to index explanatory power (...) to sciences as they are formulated at particular times. While we may thereby reduce more than philosophers have supposed, we must abandon hope (as Nagel did) of saying anything useful about reductionism. (shrink)

Speech unfolds over time, and the cues for even a single phoneme are rarely available simultaneously. Consequently, to recognize a single phoneme, listeners must integrate material over several hundred milliseconds. Prior work contrasts two accounts: (a) a memory buffer account in which listeners accumulate auditory information in memory and only access higher level representations (i.e., lexical representations) when sufficient information has arrived; and (b) an immediate integration scheme in which lexical representations can be partially activated on the basis of early (...) cues and then updated when more information arises. These studies have uniformly shown evidence for immediate integration for a variety of phonetic distinctions. We attempted to extend this to fricatives, a class of speech sounds which requires not only temporal integration of asynchronous cues (the frication, followed by the formant transitions 150–350 ms later), but also integration across different frequency bands and compensation for contextual factors like coarticulation. Eye movements in the visual world paradigm showed clear evidence for a memory buffer. Results were replicated in five experiments, ruling out methodological factors and tying the release of the buffer to the onset of the vowel. These findings support a general auditory account for speech by suggesting that the acoustic nature of particular speech sounds may have large effects on how they are processed. It also has major implications for theories of auditory and speech perception by raising the possibility of an encapsulated memory buffer in early auditory processing. (shrink)

Neural engineering technologies such as implanted deep brain stimulators and brain-computer interfaces represent exciting and potentially transformative tools for improving human health and well-being. Yet their current use and future prospects raise a variety of ethical and philosophical concerns. Devices that alter brain function invite us to think deeply about a range of ethical concerns—identity, normality, authority, responsibility, privacy, and justice. If a device is stimulating my brain while I decide upon an action, am I still the author of the (...) action? Does a device make the interiority of my experience accessible to others? Will the device change the way I think of myself and others think of me? Such fundamental questions arise even when a device is designed for only a relatively circumscribed purpose, such as restoring functioning via a smart prosthetic. We are part of a National Science Foundation-funded Engineering Research Center tasked with investigating philosophical and social implications of neural engineering research and technologies. Neural devices already in clinical use, such as deep brain stimulators for Parkinson's disease or essential tremor, have spurred healthy debate about such implications. Devices currently under development—such as the BrainGate System of implanted brain sensors coupled to robotics in persons with paralysis, exoskeletons for augmented movement, transcranial do-it-yourself stimulators, closed-loop brain stimulating systems, or even brain-to-brain interfacing—promise to extend and deepen these debates. At our center, brain-computer interfaces are the principal focus of work. Even acknowledging that the clinical translation of neural devices and seamless integration by end users may still largely reside in the future, the potential these devices hold calls for careful early analysis. The launching of the Brain Research through Advancing Innovative Neurotechnologies Initiative in April 2013 provides further impetus for this work. (shrink)

Implantable brain–computer interface technology is an expanding area of engineering research now moving into clinical application. Ensuring meaningful informed consent in implantable BCI research is an ethical imperative. The emerging and rapidly evolving nature of implantable BCI research makes identification of risks, a critical component of informed consent, a challenge. In this paper, 6 core risk domains relevant to implantable BCI research are identified—short and long term safety, cognitive and communicative impairment, inappropriate expectations, involuntariness, affective impairment, and privacy and security. (...) Work in deep brain stimulation provides a useful starting point for understanding this core set of risks in implantable BCI. Three further risk domains—risks pertaining to identity, agency, and stigma—are identified. These risks are not typically part of formalized consent processes. It is important as informed consent practices are further developed for implantable BCI research that attention be paid not just to disclosing core research risks but exploring the meaning of BCI research with potential participants.

In a recent set of articles (Klein et al., 2023; Klein & Loftus, 2024), my colleagues and I used the logic of adaptationism—the application of evolutionary principles to study the functional design of naturally selected systems (e.g., Klein et al., 2002)—to help make sense of the role natural selection played in the evolution of consciousness. To avoid well-known, seemingly intractable problems that accompany efforts to explain “how consciousness is possible in a world that consists in physical objects (...) and their relations” (the so-called “hard problem of consciousness”), we limited investigation to the question of “why natural selection favored consciousness?” In the present article, I try to make amends for this evasion by addressing some of the conceptual challenges posed by the hard problem. Drawing on insights from Klein et al.’s (2023) evolutionary excursion into the why of consciousness, I identify a potential alteration in the referential identity of “subject” and “object” when they are taken as properties of a mental state, and discuss how these changes might offer insight into the how question of consciousness.

First-generation students are more likely to feel misplaced and struggle at university than students with university-educated parents. We assumed that the shutdowns during the Coronavirus-pandemic would particularly threaten FGS due to obstructed coping mechanisms. Specifically, FGS may show lower identification with the academic setting and lower perceived fairness of the university system. We investigated whether FGS and CGS used different defenses to cope with the shutdown threat in a large sample of German-speaking students. Using Structural Equation Modeling, we found that (...) for all students, independent of academic parental background, high levels of system justification were associated with perceiving the learning situation as less threatening, better coping with failure, and less helplessness. However, in comparison to CGS, FGS showed small but significant reductions in system justification and relied more on concrete personal relationships with other students as well as their academic identity to cope with the threatening situation. We discuss implications for helping FGS succeed at university. (shrink)

Ame, vie, souffle, qui saurait bien les distinguer exactement?1like heartburn, a pronounced discomfort with the very idea of consciousness followed the early days of experimental psychology. Received wisdom has it that psychologists came to mistrust consciousness for largely behaviorist reasons—they are supposed to have worried about the alleged impossibility of performing quantifiable, repeatable measurements on an essentially private phenomenon.2 But this is a historical distortion, one that obscures some interesting and earlier philosophical concerns about the scientific study of consciousness.Behaviorists rejected (...) the scientific respectability of consciousness, to be sure.

In Section I, I criticize the view, implied by the concept of rational economic man, that feelings are inherently opposed to rationality. I attempt to show that emotions or feelings are essential to the proper functioning of reason, rational objectivity, and practical rationality or rational decision making. In addition, I argue that emotions can help to resolve certain ethical dilemmas. In Section II, I consider business writers who criticize business for overemphasizing the head at the expense of feelings or the (...) heart. In Section III, I discuss the connection between material self-interest (as manifested in trade) – a concept of rational economic man – and business virtues. (shrink)

Kohler's experiments with inverting goggles are often thought to support enactivism by showing that visual re-inversion occurs simultaneous with the return of sensorimotor skill. Closer examination reveals that Kohler's work does not show this. Recent work by Linden et al. shows that re-inversion, if it occurs at all, does not occur when the enactivist predicts. As such, the empirical evidence weighs against enactivism.

Vivimos en una sociedad en la que lo digital lo ha invadido todo. Han se ha ocupado de analizar este cambio desde la perspectiva antropológica y social, con una posición radicalmente crítica. Para Han el medio digital es un medio que nos re-programa. El cambio principal consiste en que desaparece lo que Han llama la “negatividad”. La negatividad aparece como aquello que no es positivo, que no es puesto (positum) por el individuo, sino que le viene dado y se percibe (...) inicialmente como límite. Esa negatividad de lo dado tiene múltiples manifestaciones: es lo no-inmediato, lo extraño, lo otro, lo que produce pesar y resistencia. Esta transformación hacia la transparencia “es una coacción sistémica que se apodera de todos los sucesos sociales y los somete a un profundo cambio”. Esto afecta incluso al hombre mismo, que es convertido también en un elemento funcional del sistema. Han analiza esa coacción violenta de la transparencia digital, y su omnipresencia, desde distintos enfoques a lo largo de sus libros. De ellos hemos seleccionado cinco: las relaciones personales (respeto y confianza), las relaciones comerciales (el mercado), las relaciones políticas y las relaciones con la realidad, mediadas por nuestro entendimiento del espacio y el tiempo.

Novel neurotechnologies, like deep brain stimulation and brain‐computer interface, offer great hope for treating, curing, and preventing disease, but raise important questions about effects these devices may have on human identity, authenticity, and autonomy. After briefly assessing recent narrative work in these areas, we show that agency is a phenomenon key to all three goods and highlight the ways in which neural devices can help to draw attention to the relational nature of our agency. Drawing on insights from disability theory, (...) we argue that neural devices provide a kind of agential assistance, similar to that provided by caregivers, family, and others. As such, users and devices participate in a kind of co‐agency. We conclude by suggesting the need for developing relational agency‐competencies—skills for reflecting on the influence of devices on agency, for adapting to novel circumstances ushered in by devices, and for incorporating the feedback of loved ones and others about device effects on agency.

Clinical neuroethics and neuroskepticism are recent entrants to the vocabulary of neuroethics. Clinical neuroethics has been used to distinguish problems of clinical relevance arising from developments in brain science from problems arising in neuroscience research proper. Neuroskepticism has been proposed as a counterweight to claims about the value and likely implications of developments in neuroscience. These two emergent streams of thought intersect within the practice of neurology. Neurologists face many traditional problems in bioethics, like end of life care in the (...) persistent vegetative state, determination of capacity in progressive dementia, and requests for assisted suicide in cognition-preserving neurodegenerative disease (like amyotrophic lateral sclerosis). Neurologists also look to be at the forefront of downstream clinical applications of neuroscience, like pharmacological enhancement of mental life. At the same time, the practice of neurology, concerned primarily with the structure, function, and treatment of the nervous system, has historically fostered a kind of skeptical attitude toward its own subject matter. Not all problems that appear primarily neurological are primarily neurological. This disciplinary skepticism is generally clinical in orientation and limited in scope. The rise of interest in clinical neuroethics and in neuroskepticsim generally suggests a possible broader application. The clinical skepticism of neurology provides impetus for thinking about the appropriate role for skepticism in clinical areas of neuroethics. After a brief review of neuroskepticism and clinical neuroethics, a taxonomy of clinical neuroskepticism is offered and reasons why a stronger rather than weaker form of clinical neuroskepticism is currently warranted.

Maura Tumulty has raised two objections to my imperative account of pain.1 First, she argues that there is a disanalogy between pains and other imperative sensations like itch, hunger, and thirst. Suppose (with Hall) one thinks that an itch says “Scratch here!”2 Scratch the itch, and it dutifully disappears. Not so with pain. The pain of a broken ankle has the content ‘Do not put weight on that ankle!’ Yet the coddled ankle still throbs: obeying the imperative does not extinguish (...) it. Second, Tumulty argues that the imperative account cannot handle certain pains, particularly pains of the deep viscera. On my account, pains proscribe against taking action with the painful body part. Yet some pains are associated with body parts over which we have no control. Kidney stones cause intense pain, but I cannot (voluntarily) control my kidney. What action, then, could that pain possibly proscribe? Lacking such a story, it is hard to say (as I do) that pains are exhausted by their imperative content. (shrink)

In an interdisciplinary discussion with an international group of experts, we address the question of why faces matter so much. We approach the issue from different academic, technological and artistic perspectives and integrate these different perspectives in an open dialogue in order to raise awareness about the importance of faces at a time when we are hiding them more than ever, be it in “facing” other human beings or in “facing” digital technology.

"Dreaming with open eyes" is a tagline for Spinoza's critique of Descartes; the dreams in question are principally those of volition and the active imagination. In this article, I compare the Cartesian theory of imagination as an active, but not fully rational, power of the mind and the Cartesian account of the volitional self to Spinoza's views. Descartes's own dreams and theories of dreaming are the focus of the first part of the article. Thereafter I examine Spinoza's critique of Descartes (...) and his alternative account of imagination. Finally, I argue that there is a positive sense of dreaming with open eyes to be recuperated in Spinoza's thought. Construed positively, to dream with open eyes is to understand dreams and imagination as natural phenomena and so to be able to respond constructively to them in ethical and political, as well as epistemological, life.

A common refrain in and outside academia is that prominent sports figures ought to engage more in the public discourse about political issues. This idea parallels the idea that athletes ought to be role models in general. This paper first examines and critiques the “athlete as role model” argument and then applies this critique to the “athlete as political activist” argument. Appealing to the empirical political psychological literature, the paper sketches an argument that athlete activism might actually do more harm (...) than good. (shrink)

Implanted medical devices—for example, cardiac defibrillators, deep brain stimulators, and insulin pumps—offer users the possibility of regaining some control over an increasingly unruly body, the opportunity to become part “cyborg” in service of addressing pressing health needs. We recognize the value and effectiveness of such devices, but call attention to what may be less clear to potential users—that their vulnerabilities may not entirely disappear but instead shift. We explore the kinds of shifting vulnerabilities experienced by people with Parkinson’s disease (PD) (...) who receive therapeutic deep brain stimulators to help control their tremors and other symptoms of PD.

In part 1 of the paper, I develop a Platonic business ethic, emphasizing Plato’s Republic. I approach business ethics from a virtue ethics position, and I attempt to show that a Platonic craftsmanship model infuses a corporation with a type of managerial wisdom and justice, molds temperate and courageous corporate characters, and entails a morally fine type of self-interest. I also show that it is basic to two influential management theories.In part 2, I use Amartya Sen’s Development as Freedom to (...) show that the craftsmanship model is central to the concept of development. This concept is important in ethical discussions of both globalization and transnational corporations. Thus, I attempt to globalize Platonic business ethics using a craftsmanship model.In my concluding remarks, I attempt to show that the Plato/Sen position on development can be illustrated by both American and non-American capitalist firms functioning in our globalized world.

Although the dream narrative, of (bio)logical necessity, originates with the dreamer, s/he typically does not know this. For the dreamer, the dream world is the real world. In this article I argue that this nightly misattribution is best explained in terms of the concept of mental ownership (e.g., Albahari, 2006; Klein, 2015a; Lane, 2012). Specifically, the exogenous nature of the dream narrative is the result of an individual assuming perspectival, but not personal, ownership of content s/he authored (i.e., “The (...) content in my head is not mine. Therefore it must be peripherally perceived”). Situating explanation within a theoretical space designed to address questions pertaining to the experienced origins of conscious content has a number of salutatory consequences. For example, it promotes predictive fecundity by bringing to light empirical generalizations whose presence otherwise might have gone unnoticed (e.g., the severely limited role of mental time travel within the dream narrative). -/- .

I. Les facultés qui se rapportent à l'image des objets en nous, — l'imagination au sens large, — constituent, selon une tradition qui vient d'Aristote, l'intermédiaire entre la sensibilité et l'intellect. Le moyen âge les désigna par le nom de sens intérieurs ; leur liste fut reprise et modifiée par Ficin (dont la source directe n'est pas Avicenne, mais Albert le Grand) et par Bruno. Dans l'interprétation des néoplatoniciens, la série des facultés connaissantes représente le chemin de l'âme dans la (...) conversion ; la phantasia y joue un rôle eminent (Plotin, Hugues de Saint-Victor, Ficin, Bruno) ; d'autre part, on fait correspondre à la faculté intermédiaire une âme intermédiaire qui lui sert de substrat (Lulle), et un « premier corps » ou « véhicule » de l'âme (le spiritus phantasticus ou őχημα-πνεῦμα de Synesius). L'idée reparaît, modifiée, chez Hugues de Saint-Victor, Ficin, Bruno. Ce dernier met le spiritus phantasticus en relation avec l'âme du monde, qui lui est consubstantielle, la « lumière précédant toute Création » qui nous fait voir les images de nos rêves. Sources : Porphyre, Cusanus repris par Ficin, le panthéisme médiéval. Le lien entre le spiritus phantasticus et le destin de l'âme, esquissé chez Plotin, Porphyre, le Pseudo-Jamblique, Synesius, est affirmé sous différentes formes par Hugues, Ficin et Bruno : le sujet des peines infernales, qui sont d'ailleurs chez Ficin et Bruno de nature imaginaire, est un corps subtil. Ces peines correspondent exactement à ce que nos appétits et notre imagination ont fait de la substance de notre âme. Le spiritus phantasticus se rapproche, notamment chez Ficin, d'une sorte de karma. II. Dans la branche descendante de la connaissance, l'application de l'universel au particulier est forcément liée au sens intérieur et on l'attribue à une faculté spéciale, la Urteilskraft au sens kantien. Bruno en fait une fonction de l'imagination. D'autre part, les arts universels ou lulliens ont pris de plus en plus, durant la Renaissance, l'aspect de topiques généralisées ; le nerf de la méthode y était donc toujours cette Urteilskraft. Il s'en suit, chez Bruno, que le sujet de l'art universel est l'imagination, qui devient ainsi la source première de tout acte de l'intellect, principe de la fécondité infinie de la pensée. (Pratiquement, d'ailleurs, les artes de Bruno sont des ensembles d'images). III. Aux théories de l'imagination répondent les théories de l'image, « vêtement » et « premier corps » de la pensée. On vérifie cette correspondance, d'une part, dans la théorie du symbole, — avec ses variantes métaphysiques, pansymbolisme, magie, — et, d'autre part, dans celle du concetto (rapport entre la pensée et l'expression), où l'on va jusqu'à l'idée d'un universel de l'imagination, et du dessin comme concept. — Une importante différence entre la nature du symbolisme selon Pic et l'idée que s'en fait Bruno s'explique par leurs conceptions différentes de l'imagination. La théorie de l'art et l'évolution du goût artistique sont, dans leurs grandes lignes, en concordance avec ce qu'impliquent ou suggèrent à ce sujet les théories de l'imagination et de l'image.

Philosophers have sought to characterize a type of knowledge — what I call real knowledge — which is significantly different from the ordinary concept of knowledge. The concept of knowledge as true, justified belief — what I call knowledge simpliciter — failed to depict the sought after real knowledge because the necessary and jointly sufficient conditions of knowledge simpliciter can be felicitously but accidentally fulfilled. Real knowledge is knowledge simpliciter plus a set of requirements which guarantee that the truth, belief (...) and justification conditions are not accidentally conjoined. Two of those requirements have received considerable attention in recent literature by the defeasibility theorists and the causal theorists. I argue that a third requirement is needed to block the merely coincidental cosatisfaction of the belief and justification conditions and to capture our intuitions about the epistemic agent who possesses real knowledge. That condition ascribes a disposition to the real knower to believe all and only justified propositions in virtue of his/her belief that the propositions are justified. Two consequences of that requirement are discussed: (1) if S really knows that p, then S knows simpliciter that S knows simpliciter that p and (2) the iterative feature of real knowledge mentioned in (1) provides a basis for the rejection of a particularly pernicious form of scepticism.

American teachings use the idea of shields to describe how we meet, receive and respond to the world, and I have found some equivalencies in Eastern teachings, as well. I’ll tell you about a few that I’ve learned, and then we’ll expand those ideas to embrace the core ideas of this book.

We study two logics of knowledge and belief stemming from the work of Stalnaker, omitting positive introspection for knowledge. The two systems are equivalent with positive introspection, but not without. We show that while the logic of beliefs remains unaffected by omitting introspection for knowledge in one system, it brings significant changes to the other. The resulting logic of belief is non-normal, and its complete axiomatization uses an infinite hierarchy of coherence constraints. We conclude by returning to the philosophical interpretation (...) underlying both models of belief, showing that neither is strong enough to support a probabilistic interpretation, nor an interpretation in terms of certainty or the “mental component” of knowledge.
