Ethical thought experiments such as the trolley dilemma have been investigated extensively in the past, showing that humans act in utilitarian ways, trying to cause as little overall damage as possible. These trolley dilemmas have gained renewed attention over the past few years, especially due to the necessity of implementing moral decisions in autonomous driving vehicles. We conducted a set of experiments in which participants experienced modified trolley dilemmas as drivers in virtual reality environments. Participants had to make decisions between (...) driving in one of two lanes where different obstacles came into view. Eventually, the participants had to decide which of the objects they would crash into. Obstacles included a variety of human-like avatars of different ages and group sizes. Furthermore, the influence of sidewalks as potential safe harbors and a condition implicating self-sacrifice were tested. Results showed that participants, in general, decided in a utilitarian manner, sparing the highest number of avatars possible with a limited influence by the other variables. Derived from these findings, which are in line with the utilitarian approach in moral decision making, it will be argued for an obligatory ethics setting implemented in ADVs. (shrink)

Change-blindness occurs when large changes are missed under natural viewing conditions because they occur simultaneously with a brief visual disruption, perhaps caused by an eye movement, a flicker, a blink, or a camera cut in a film sequence. We have found that this can occur even when the disruption does not cover or obscure the changes. When a few small, high-contrast shapes are briefly spattered over a picture, like mudsplashes on a car windscreen, large changes can be made simultaneously (...) in the scene without being noticed.

Change blindness is the striking failure to see large changes that normally would be noticed easily. Over the past decade this phenomenon has greatly contributed to our understanding of attention, perception, and even consciousness. The surprising extent of change blindness explains its broad appeal, but its counterintuitive nature has also engendered confusions about the kinds of inferences that legitimately follow from it. Here we discuss the legitimate and the erroneous inferences that have been drawn, and offer a set (...) of requirements to help separate them. In doing so, we clarify the genuine contributions of change blindness research to our understanding of visual perception and awareness, and provide a glimpse of some ways in which change blindness might shape future research.

Perhaps the most striking phenomenon of visual awareness is inattentional blindness (IB), in which a surprisingly salient event right in front of you may go completely unseen when unattended. Does IB reflect a failure of perception, or only of subsequent memory? Previous work has been unable to answer this question, due to a seemingly intractable dilemma: ruling out memory requires immediate perceptual reports, but soliciting such reports fuels an expectation that eliminates IB. Here we introduce a way of evoking (...) repeated IB in the same subjects and the same session: we show that observers fail to report seeing salient events’ not only when they have no expectation, but also when they have the wrong expectations about the events nature. This occurs when observers must immediately report seeing anything unexpected, even mid-event. Repeated IB thus demonstrates that IB is aptly named: it reflects a genuine deficit in moment-by-moment conscious perception, rather than a form of inattentional amnesia. (shrink)

This paper defends a desire-based understanding of pleasurable and unpleasant experiences. More specifically, the thesis is that what makes an experience pleasant/unpleasant is the subject having a certain kind of desire about that experience. I begin by introducing the ‘Desire Account’ in more detail, and then go on to explain and refute a prominent set of contemporary counter-examples, based on subjects who might have ‘Reflective Blindness’, looking particularly at the example of subjects with depression. I aim to make the (...) Desire Account more persuasive, but also to clear up more widespread misunderstandings about depression in metaethics. For example, mistakes that are made by conflating two of depression’s most prominent symptoms: depressed mood and anhedonia. (shrink)

Willful blindness is not an appropriate substitute for knowledge in crimes that require a mens rea of knowledge because an actor who contrives his own ignorance is only sometimes as culpable as a knowing actor. This paper begins with the assumption that the classic willfully blind actor—the drug courier—is culpable. If so, any plausible account of willful blindness must provide criteria that find this actor culpable. This paper then offers two limiting cases: a criminal defense lawyer defending a (...) client he suspects of perjury and a pain doctor who suspects his patient may be lying about her pain. The paper argues that each of these actors is justified in cultivating ignorance about his client’s or patient’s truthfulness. If this is right, then a good theory of willful blindness must distinguish these cases. The article argues that neither Husak & Callender’s motivation-based account of willful blindness nor the recklessness account is able to do so. The paper proposes the following alternative: contrived ignorance constitutes culpable blindness when the decision to remain blind or to cultivate blindness is not itself justified. This Justification approach meshes with our intuitions about willfully blind drug couriers as well as willfully blind lawyers and doctors. (shrink)

This paper discusses the so-called non-interference assumption (NIA) grounding causal inference in trials in both medicine and the social sciences. It states that for each participant in the experiment, the value of the potential outcome depends only upon whether she or he gets the treatment. Drawing on methodological discussion in clinical trials and laboratory experiments in economics, I defend the necessity of partial forms of blinding as a warrant of the NIA, to control the participants’ expectations and their strategic interactions (...) with the experimenter.

De blinde vlek in praktijk en discussie rond orgaandonatie In countries like Belgium and The Netherlands, there seems to be overwhelming public acceptance of transplantation and organ donation. Yet, paradoxically, part of the public refuses post-mortal donation of their own organs or of those of family members. It is customary within the transplantation context to accept the refusal of organ donation by family members “in order to accommodate their feelings”. I argue that this attitude does not take seriously what is (...) really behind the refusal of donation by (at least some) family members. My hypothesis is that even in very secularized societies, this refusal is determined by cultural-symbolic attitudes vis-à-vis the (dead) human body (and some of its parts). The blind spot for this reality, both in the practice of and discussions around organ donation, prevents understanding of what is producing the paradox mentioned. (shrink)

Animal ethicists have recently debated the ethical questions raised by disenhancing animals to improve their welfare. Here, we focus on the particular case of breeding hens for commercial egg-laying systems to become blind, in order to benefit their welfare. Many people find breeding blind hens intuitively repellent, yet ‘welfare-only’ positions appear to be committed to endorsing this possibility if it produces welfare gains. We call this the ‘Blind Hens’ Challenge’. In this paper, we argue that there are both empirical and (...) theoretical reasons why even those adopting ‘welfare-only’ views should be concerned about breeding blind hens. But we also argue that alternative views, which (for example) claim that it is important to respect the telos or rights of an animal, do not offer a more convincing solution to questions raised by the possibility of disenhancing animals for their own benefit.

The paper asks under what conditions deductive reasoning transmits justification from its premises to its conclusion. It argues that both standard externalist and standard internalist accounts of this phenomenon fail. The nature of this failure is taken to indicate the way forward: basic forms of deductive reasoning must justify by being instances of 'blind but blameless' reasoning. Finally, the paper explores the suggestion that an inferentialist account of the logical constants can help explain how such reasoning is possible.

What does it mean to see someone as human, as a member of humankind? What kind of call for justice is it to demand that a group be seen as human beings? This article explores a fundamental kind of injustice: one of perception and how we respond to our perceptions. Drawing on Cavell, Wittgenstein and Rancière, we elucidate “soul blindness” as a distinct and basic form of injustice. Rancière’s police orders and Cavell’s soul blindness are mutually constitutive; the (...) undoing of police orders entails a politics of soul dawning. Soul dawning entails acknowledging the humanity of others without erasing difference. In the concluding section, we consider white obliviousness to the Black Lives Matters (BLM) movement as a case of soul blindness. Part of the political import of BLM is its capacity to illustrate how practices of soul blindness in the United States constitute whiteness in a racialized police order. (shrink)

Over the last four decades arguments for and against the claim that creative hypothesis formation is based on Darwinian ‘blind’ variation have been put forward. This paper offers a new and systematic route through this long-lasting debate. It distinguishes between undirected, random, and unjustified variation, to prevent widespread confusions regarding the meaning of undirected variation. These misunderstandings concern Lamarckism, equiprobability, developmental constraints, and creative hypothesis formation. The paper then introduces and develops the standard critique that creative hypothesis formation is guided (...) rather than blind, integrating developments from contemporary research on creativity. On that basis, I discuss three compatibility arguments that have been used to answer the critique. These arguments do not deny guided variation but insist that an important analogy exists nonetheless. These compatibility arguments all fail, even though they do so for different reasons: trivialisation, conceptual confusion, and lack of evidence respectively. Revisiting the debate in this manner not only allows us to see where exactly a ‘Darwinian’ account of creative hypothesis formation goes wrong, but also to see that the debate is not about factual issues, but about the interpretation of these factual issues in Darwinian terms.

Unorthodox speakers who reject the inferences in an alleged possession condition can still have the concept by understanding a word for it. In that sense, the inferences are not analytic. Inferentialist accounts of logical constants, theoretical terms (using the Ramsey-Carnap-Lewis method) and pejorative expressions such as ’Boche’ are examined and rejected. It is suggested that epistemological questions cannot be reduced to questions in the theory of thought and meaning. (shrink)

Abstract: To evaluate the explanation of change blindness in terms of misrepresentation and determine its role for Rosenthal’s higher-order thought theory of consciousness, we present an alternative account of change blindness that affords an independent outlook and provides a viable alternative. First we describe Rosenthal’s actualism and the notion of misrepresentation, then introduce change blindness and the explanation of it by misrepresentation. Rosenthal asserts that, in change blindness, the first-order state tracks the post-change stimulus, but the (...) higher-order state misrepresents it. We propose the alternative that both post-change and pre-change content can be tracked by the first-order state, and that in change blindness the higher-order thought represents the pre-change state, resulting in a good-enough representation: true but not veridical. We compare the two explanations with respect to available data and analyse the principal theoretical claims. Discussing the rationale of the alternative account, we conclude that there is good reason to conceive of the mind as satisficing, geared towards reliability instead of truth-tracking, and guided by representations that are good enough as opposed to complete or corresponding to the facts. We end with some methodological remarks concerning the risk of cognitive biases in interdisciplinary research that brings together empirical and philosophical claims. (shrink)

This article examines the contradictions inherent in blind women’s appearance management. Based on an anthropological analysis of interviews with 40 blind women in Israel, the article argues that while serving as a valuable tool within stigma management, appearance management operates simultaneously as a site of rigorous discipline of the body in an effort to comply with feminine visual norms, and as a vehicle for the expression and reception of sensory pleasure. It argues for the significant role of blind women’s appearance (...) in negotiating normalcy and rejecting the normative, stigmatizing script written for them as disabled-blind-women. By studying the role of appearance in the lives of women who do not rely on sight as a central mode of perception, the article addresses the complicated position of blind women in visual culture and challenges the traditional ocular focus of the study of feminine identity and gender performance.

In this article, I critically assess Hélène Landemore's new model of Open Democracy, asking whether it requires of citizens to blindly defer to the decisions of the mini-public. To address this question, I, first, discuss three institutional mechanisms in Open Democracy, all of which can be read to grant citizens democratic control. I argue that neither the capacity to authorize the selection mechanism (random sortition), nor the lottocratic conception of political equality, nor the self-selection mechanisms of Landemore's model deliver the (...) form of control that would insulate Open Democracy from the charge of blind deference. I then discuss the direct democracy mechanisms that Landemore incorporates into her model. Although these devices grant citizens control and, by extension, offer the resources for repudiating the charge of blind deference, they also, I argue, subvert the logic of Landemore's lottocratic model, rendering Open Democracy predictably unstable. Given the deliberative asymmetries between the mini-public and the citizenry, a high frequency of bottom-up challenges is to be expected that would throw the whole system into jeopardy. Thus, the challenge for lottocrats is to show how democratic control can be achieved in a lottocratic system without undermining the benefits of the legislature by lot. (shrink)

Sighted speakers of different languages vary systematically in how they package and order components of a motion event in speech. These differences influence how semantic elements are organized in gesture, but only when those gestures are produced with speech, not without speech. We ask whether the cross-linguistic similarity in silent gesture is driven by the visuospatial structure of the event. We compared 40 congenitally blind adult native speakers of English or Turkish to 80 sighted adult speakers as they described three-dimensional (...) motion scenes. We found an effect of language on co-speech gesture, not on silent gesture—blind speakers of both languages organized their silent gestures as sighted speakers do. Humans may have a natural semantic organization that they impose on events when conveying them in gesture without language—an organization that relies on neither visuospatial cues nor language structure.

Bringing sex and philosophy together on a blind date, Anne Dufourmantelle’s provocative study uses this analogy to uncover and examine philosophy’s blind spot. Delightful and startling comparisons spring from the date: both sex and philosophy are dangerous, both are socially subversive, and both are obsessions. Although sex and philosophy have much in common, however, they have scarcely known one another until now. Socrates and Diogenes had little to say about sex, and although it was notoriously explored by the Marquis de (...) Sade, this study explains why philosophy has never been fully sexualized nor sex really philosophized. Blind Date highlights the marked deletion of sexual topics and themes from philosophical works, while also opening doors for their union. Inviting readers to remember that thought does not require repressed desire, Dufourmantelle argues that sex is everywhere, and it affects all kinds of thinking. (shrink)

Since the outbreak of COVID-19, governments have turned their attention to digital contact tracing. In many countries, public debate has focused on the risks this technology poses to privacy, with advocates and experts sounding alarm bells about surveillance and mission creep reminiscent of the post 9/11 era. Yet, when Apple and Google launched their contact tracing API in April 2020, some of the world’s leading privacy experts applauded this initiative for its privacy-preserving technical specifications. In an interesting twist, the tech (...) giants came to be portrayed as greater champions of privacy than some democratic governments. This article proposes to view the Apple/Google API in terms of a broader phenomenon whereby tech corporations are encroaching into ever new spheres of social life. From this perspective, the advantage these actors have accrued in the sphere of the production of digital goods provides them with access to the spheres of health and medicine, and more worrisome, to the sphere of politics. These sphere transgressions raise numerous risks that are not captured by the focus on privacy harms. Namely, a crowding out of essential spherical expertise, new dependencies on corporate actors for the delivery of essential, public goods, the shaping of public policy by non-representative, private actors and ultimately, the accumulation of decision-making power across multiple spheres. While privacy is certainly an important value, its centrality in the debate on digital contact tracing may blind us to these broader societal harms and unwittingly pave the way for ever more sphere transgressions.

When confronted with an ethical dilemma, most of us like to think we would stand up for our principles. But we are not as ethical as we think we are. In Blind Spots, leading business ethicists Max Bazerman and Ann Tenbrunsel examine the ways we overestimate our ability to do what is right and how we act unethically without meaning to. From the collapse of Enron and corruption in the tobacco industry, to sales of the defective Ford Pinto, the downfall (...) of Bernard Madoff, and the Challenger space shuttle disaster, the authors investigate the nature of ethical failures in the business world and beyond, and illustrate how we can become more ethical, bridging the gap between who we are and who we want to be. Explaining why traditional approaches to ethics don't work, the book considers how blind spots like ethical fading--the removal of ethics from the decision--making process--have led to tragedies and scandals such as the Challenger space shuttle disaster, steroid use in Major League Baseball, the crash in the financial markets, and the energy crisis. The authors demonstrate how ethical standards shift, how we neglect to notice and act on the unethical behavior of others, and how compliance initiatives can actually promote unethical behavior. They argue that scandals will continue to emerge unless such approaches take into account the psychology of individuals faced with ethical dilemmas. Distinguishing our "should self" from our "want self", the authors point out ethical sinkholes that create questionable actions. Suggesting innovative individual and group tactics for improving human judgment, Blind Spots shows us how to secure a place for ethics in our workplaces, institutions, and daily lives. (shrink)

On Blindness opens the eyes of the sighted to the world as experience by the blind, offering a unique opportunity to explore the challenges, frustrations, joys - and extraordinary insights - experienced in the everyday business of discovering the world without sight. What difference doessight or its absence make to our ideas about the world? What begins as a philosophical exchange between the noted philosopher and broadcaster Bryan Magee and the late Martin Milligan, activist and philosopher blind almost from (...) birth, develops into a personal and intense discussion of the implications of blindness. The debate is vigorous and oftenheated; sometimes contentious, it is always stimulating. In discussing the range of blind experience, from those born blind to those who became blind - including those who have to cope with the shock of gaining sight they had never before possessed - On Blindness argues strongly against the notionthat blindness is a simple experience. This extraordinary book casts new light on one of the most fundamental aspects of human experience. It will make fascinating reading for anyone interested in sight and blindness from a personal, practical or philosophical point of view. This dictionary is intended for anyone who enjoys food andwould like a handy, non-technical guide to the terms they encounter on food labels, in advertising or in the media. Its broad coverage of food and nutrition makes it invaluable for consumers, cooks, and a range of students and practitioners in the fields of catering, home economies, foodtechnology, and health care.

For a long time, ‘culture’ appears only to be an effect of the power of discourses and media in Friedrich Kittler’s works.

Why absolute certainty is impossible in science In today's unpredictable and chaotic world, we look to science to provide certainty and answers—and often blame it when things go wrong. The Blind Spot reveals why our faith in scientific certainty is a dangerous illusion, and how only by embracing science's inherent ambiguities and paradoxes can we truly appreciate its beauty and harness its potential. Crackling with insights into our most perplexing contemporary dilemmas, from climate change to the global financial meltdown, this (...) book challenges our most sacredly held beliefs about science, technology, and progress. At the same time, it shows how the secret to better science can be found where we least expect it—in the uncertain, the ambiguous, and the inevitably unpredictable. William Byers explains why the subjective element in scientific inquiry is in fact what makes it so dynamic, and deftly balances the need for certainty and rigor in science with the equally important need for creativity, freedom, and downright wonder. Drawing on an array of fascinating examples—from Wall Street's overreliance on algorithms to provide certainty in uncertain markets, to undecidable problems in mathematics and computer science, to Georg Cantor's paradoxical but true assertion about infinity—Byers demonstrates how we can and must learn from the existence of blind spots in our scientific and mathematical understanding. The Blind Spot offers an entirely new way of thinking about science, one that highlights its strengths and limitations, its unrealized promise, and, above all, its unavoidable ambiguity. It also points to a more sophisticated approach to the most intractable problems of our time. (shrink)

Background: The phenomenon of forceful physical restraint in pediatric care is an ethical issue because it confronts professionals with the dilemma of using force for the child’s best interest. This is a paradox. The perspective of healthcare professional working in pediatric wards needs further in-depth investigations. Purpose: To explore the perspectives and behaviors of healthcare professionals toward forceful physical restraint in pediatric care. Methods: This qualitative ethnographic study used focus groups with purposeful sampling. Thirty volunteer healthcare professionals (nurses, hospital aids, (...) physiotherapists, and health educators) were recruited in five pediatric facilities in four hospitals around Paris, France, from March to June 2013. The data were processed using NVIVO software (QSR International Ltd. 1999–2013). The data analysis followed a qualitative methodological process. Ethical Considerations: The research was conducted in compliance with the Declaration of Helsinki. Written informed consent was collected systematically from participants. Findings: This study provides elements to help understand why restraint remains common despite its contradiction with the duty to protect the child and the child’s rights. All participants considered the use of forceful physical restraint to be a frequent difficulty in pediatrics. Greater interest in the child’s health was systematically used to justify the use of force, with little consideration for contradictory or ethical aspects. Raising the issue of forceful restraint always triggered discomfort, unease and an outpour of emotions among healthcare professionals. The findings have highlighted a form of hierarchy of duties that give priority to the execution of the technical procedure and legitimize the use of restraint. Professionals seemed to temporarily suspend their ability to empathize in order to apply restraint to carry out a technical procedure. This observation has allowed us to suggest the concept of “transient empathic blindness.” Conclusion: Using physical restraint during pediatric care was considered a common problem by participants. This practice must be questioned, and professionals must have access to training to find alternatives to strong restraint. Conceptualizing this phenomenon with the concept of “transient empathic blindness” could help professionals understand what happens in their minds when using forceful restraint. (shrink)

In this article, the authors present an ethnography of biomedical knowledge production and science collaboration when they take place in developing country contexts. The authors focus on the arrival of international clinical trials to Sri Lanka and provide analysis of what was described as one of the first multisited trials in the country, a pharmaceutical company sponsored, phase 2, randomized, double-blind, placebo controlled trial carried out between 2009 and 2010. Using interviews with those who conducted the trial and six months (...) of participant observation at the trial hospital, the authors describe the work that goes on to perform trials according to international standards. The article describes what happens when a randomized controlled trial encounters existing epistemic virtues and documents the impacts on ideas of authority, expertise and doctor–patient relationships found in Sri Lankan medicine.

Many models of (un)ethical decision making assume that people decide rationally and are in principle able to evaluate their decisions from a moral point of view. However, people might behave unethically without being aware of it. They are ethically blind. Adopting a sensemaking approach, we argue that ethical blindness results from a complex interplay between individual sensemaking activities and context factors.

Inattentional blindness is described as the failure to perceive a supra-threshold stimulus when attention is directed away from that stimulus. Based on performance on an explicit recognition memory test and concurrent functional imaging data Rees, Russell, Frith, and Driver [Rees, G., Russell, C., Frith, C. D., & Driver, J. . Inattentional blindness versus inattentional amnesia for fixated but ignored words. Science, 286, 2504–2507] reported inattentional blindness for word stimuli that were fixated but ignored. The present study examined (...) both explicit and implicit memory for fixated but ignored words using a selective-attention task in which overlapping picture/word stimuli were presented at fixation. No explicit awareness of the unattended words was apparent on a recognition memory test. Analysis of an implicit memory task, however, indicated that unattended words were perceived at a perceptual level. Thus, the selective-attention task did not result in perfect filtering as suggested by Rees et al. While there was no evidence of conscious perception, subjects were not blind to the implicit perceptual properties of fixated but ignored words. (shrink)

Digital health and welfare technologies and artificial intelligence are proposed to revolutionise healthcare systems around the world by enabling new models of care. Digital health and welfare technologies enable remote monitoring and treatments, and artificial intelligence is proposed as a means of prediction instead of reaction to individuals’ health and as an enabler of proactive care and rehabilitation. The digital transformation not only affects hospital and primary care but also how the community meets older people's needs. Community care is often (...) provided by informal and formal care‐givers, most of whom are women. Gender equality is at the heart of many national strategies, but do all genders have equal rights, responsibilities and opportunities when it comes to community care and its digital transformation? The digital transformation of community care is entangled with how care is provided to older people and the working conditions of community‐care professionals. Current and, even more so, future community‐care systems are and will be partly constituted by networks of technological artefacts. These health and welfare technological artefacts and the discourse surrounding them mediate and constitute social relations and community care. This article looks into how health and welfare technology and artificial intelligence‐based devices and systems mediate and constitute gender relations in community care and presents an argument for reflexivity, embodiment, pluralism, participation and ecology as an alternative strategy to treating community care as one‐size‐fit‐all and being blind to gender‐related issues.

According to reductive intentionalism, the phenomenal character of a conscious experience is constituted by the experience's intentional (or representational) content. The goal of this article is to show that a phenomenon in visual perception called change blindness poses a problem for this doctrine. It is argued, in particular, that phenomenal character is not sensitive, as it should be if reductive intentionalism is correct, to fine-grained variations in content. The standard anti-intentionalist strategy is to adduce putative cases in which phenomenal (...) character varies despite sameness of content. This paper explores an alternative anti-intentionalist tack, arguing, by way of a specific example involving change blindness, that content can vary despite sameness of phenomenal character.

The sensorimotor theory (Noe¨, 2004, in press) discusses a special instance of lack of perceptual experience despite no sensory impairment. The phenomenon dubbed “experiential blindness” is cited as evidence for a constitutive relation between sensorimotor skills and perceptual experience. Recently it has been objected (Adams & Aizawa, 2008; Aizawa, 2007) that the cases described by Noe¨ as experiential blindness are cases of pure sensory deficit. This paper argues that while the objections bring out limitations of Noe¨’s sensorimotor theory (...) they do not do enough to challenge a robust perception–action interdependence claim. There are genuine cases of experiential blindness and these are better explained by the hypothesis of the interdependence of perception and action rather than by a passive vision approach. The cases provide support for a strong thesis of embodied cognition where ongoing sensorimotor dynamics non-trivially constrain perceptual content. (shrink)

Haptic object recognition is usually an efficient process although slower and less accurate than its visual counterpart. The early loss of vision imposes a greater reliance on haptic perception for recognition compared to the sighted. Therefore, we may expect that congenitally blind persons could recognize objects through touch more quickly and accurately than late blind or sighted people. However, the literature provided mixed results. Furthermore, most of the studies on haptic object recognition focused on performance, devoting little attention to the (...) exploration procedures that conducted to that performance. In this study, we used iCube, an instrumented cube recording its orientation in space as well as the location of the points of contact on its faces. Three groups of congenitally blind, late blind and age and gender-matched blindfolded sighted participants were asked to explore the cube faces where little pins were positioned in varying number. Participants were required to explore the cube twice, reporting whether the cube was the same or it differed in pins disposition. Results showed that recognition accuracy was not modulated by the level of visual ability. However, congenitally blind touched more cells simultaneously while exploring the faces and changed more the pattern of touched cells from one recording sample to the next than late blind and sighted. Furthermore, the number of simultaneously touched cells negatively correlated with exploration duration. These findings indicate that early blindness shapes haptic exploration of objects that can be held in hands. (shrink)

There is considerable debate amongst philosophers as to the basic philosophical problem Wittgenstein is attempting to solve in _Philosophical Investigations_. In this bold and original work, Meredith Williams argues that it is the problem of "normative similarity". In _Blind Obedience_ Williams demonstrates how Wittgenstein criticizes traditional, representationalist theories of language by employing the ‘master/novice’ distinction of the learner, arguing that this distinction is often overlooked but fundamental to understanding philosophical problems about mind and language. The book not only provides revealing (...) discussions of Wittgenstein’s corpus but also intricate analyses of the work of Brandom, Dummett, Frege, Sellars, Davidson, Cavell and others. These are usefully compared in a bid to better situate Wittgenstein’s non-intellectualist, non-theoretical approach and to highlight is unique features. (shrink)

Normativists about belief hold that belief formation is essentially rule- or norm-guided. On this view, certain norms are constitutive of or essential to belief in such a way that no mental state not guided by those norms counts as a belief, properly construed. In recent influential work, Kathrin Glüer and Åsa Wikforss develop novel arguments against normativism. According to their regress of motivations argument, not all belief formation can be rule- or norm-guided, on pain of a vicious infinite regress. I (...) argue that the regress of motivations argument is unsuccessful: an appeal to the notion of blind rule-following, drawn from a plausible interpretation of Ludwig Wittgenstein’s remarks on rule-following, stops the regress of motivations in its tracks.

Do newborns think-do they know that 'three' is greater than 'two'? Do they prefer 'right' to 'wrong'? What about emotions--do newborns recognize happiness or anger? If they do, then how are our inborn thoughts and feelings encoded in our bodies? Could they persist after we die? Going all the way back to ancient Greece, human nature and the mind-body link are the topics of age-old scholarly debates. But laypeople also have strong opinions about such matters. Most people believe, for example, (...) that newborn babies don't know the difference between right and wrong-such knowledge, they insist, can only be learned. For emotions, they presume the opposite-that our capacity to feel fear, for example, is both inborn and embodied. These beliefs are stories we tell ourselves about what we know and who we are. They reflect and influence our understanding of ourselves and others and they guide every aspect of our lives. In a twist that could have come out of a Greek tragedy, Berent proposes that our errors are our fate. These mistakes emanate from the very principles that make our minds tick: our blindness to human nature is rooted in human nature itself. An intellectual journey that draws on philosophy, anthropology, linguistics, cognitive science, and Berent's own cutting-edge research, The Blind Storyteller grapples with a host of provocative questions, from why we are so infatuated with our brains to what happens when we die. The end result is a startling new perspective on our humanity. (shrink)

In a series of three experiments, we explored the nature of implicit representations in change blindness . Using 3 × 3 letter arrays, we asked subjects to locate changes in paired arrays separated by 80 ms ISIs, in which one, two or three letters of a row in the second array changed. In one testing version, a tone followed the second array, signaling a row for partial report . In the other version, no PR was required. After Ss reported (...) whether a change had been detected and the PR had been completed , they were asked to identify a degraded letter trigram that was either novel, or from a previously shown row . Our findings indicate that when CB occurs, both the pre-change and post-change stimulus information primes despite its unavailability to consciousness. Surprisingly, findings also indicate that when change detection occurs only the post-change information primes. (shrink)

Drawing on contemporary epistemologies of ignorance, I analyze the American ideology of color blindness as a recalcitrant form of active ignorance that operates at a meta-level. I contend that the meta-ignorance involved in color blindness operates through distorting second-order attitudes about one's cognitive and affective attitudes, resulting in cognitive and affective numbness with respect to racial matters: ignorance of one's racial ignorance and insensitivity to one's racial insensitivity. I contend that the black/white binary that has dominated the American (...) racial imagination has contributed tremendously to establish and maintain meta-blindness about racial differences. I suggest that overcoming the black/white binary demands that we expand current conceptions of racial lucidity and that we go beyond the notions of double consciousness that critical race theorists have defended since Du Bois and Fanon. According to a more expansive social pluralism, lucidity with respect to racial differences requires a kaleidoscopic consciousness that does not reinscribe the black/white binary in one's racial imagination.

Responding to commentaries from psychologists, neuroscientists, philosophers, and anthropologists, I clarify a central purpose of Cognitive Gadgets – to overcome “cognition blindness” in research on human evolution. I defend this purpose against Brunerian, extended mind, and niche construction critiques of computationalism – that is, views prioritising meaning over information, or asserting that behaviour and objects can be intrinsic parts of a thinking process. I argue that empirical evidence from cognitive science is needed to locate distinctively human cognitive mechanisms on (...) the continuum between gadgets and instincts. Focussing on that requirement, I also address specific challenges, and applaud extensions and refinements, of the evidence surveyed in my book. It has been said that “a writer's idea of sound criticism is ten thousand words of closely reasoned adulation.” I cannot disagree with this untraceable wag, but the 30 commentators on Cognitive Gadgets provided some 30,000 words of criticism that are of much greater scientific value than adulation. I am grateful to them all. The response that follows is V-shaped. It starts with the broadest conceptual and methodological issues and funnels down to matters arising from specific empirical studies.

Change blindness—our inability to detect changes in a stimulus—occurs even when the change takes place gradually, without disruption (Simons et al., 2000). Such gradual changes are more difficult to detect than changes that involve a disruption. In this experiment, we extend previous findings to the domain of facial expressions of emotions occurring in the context of a realistic scene. Even with changes occurring in central, highly relevant stimuli such as faces, gradual changes still produced high levels of change (...) class='Hi'>blindness: Detection rates were three times lower for gradual changes than for displays involving disruption, with only 15% of the observers perceiving the gradual change within a single trial. However, despite this high rate of change blindness, changes on faces were significantly better detected than color changes occurring on non facial objects in the same scene. (shrink)

In this report, the phenomenology of two blind users of a sensory substitution device – “The vOICe” – that converts visual images to auditory signals is described. The users both report detailed visual phenomenology that developed within months of immersive use and has continued to evolve over a period of years. This visual phenomenology, although triggered through use of The vOICe, is likely to depend not only on online visualization of the auditory signal but also on the users’ previous (albeit (...) distant) experience of veridical vision (e.g. knowledge of shapes and visual perspective). Once established, the sensory substitution mapping between the auditory and visual domains is not confined to when the device is worn and, thus, may constitute an example of acquired synaesthesia.

High percentages of submitted papers are rejected at editorial levels without offering a second chance to authors by sending their papers for further peer-reviews. In most cases, the rejections are typical quick answers without helpful argumentations related to the content of the rejected material. More surprisingly, some journals vaunt their high rejection rates as a “mark of prestige”!However, journals that reject high percentages of submitted papers have built their prominent positions based on a flawed measure, the impact factor, and from (...) a long and favorable historical context. Their shareholders may think that they are allowed to have a large margin of rejection rates without affecting their sponsorship or funding sources thanks to an extended anchorage since tens, or in some cases hundreds, of years compared to unknown or new journals that struggle to pave a way in the scientific publication world. Historical anchorage of some journals also makes it unfair to compare old and new .. (shrink)

Blind Realism originated in the deeply felt conviction that the widespread acceptance of Gettier-type counterexamples to the classical definition of knowledge rests in a demonstrably erroneous understanding of the nature of human knowledge. In seeking to defend that conviction, Robert F. Almeder offers a fairly detailed and systematic picture of the nature and limits of human factual knowledge.

In this paper, I defend a grammatical account of scalar implicatures. In particular, I submit new evidence in favor of the contextual blindness principle, assumed in recent versions of the grammatical account. I argue that mismatching scalar implicatures can be generated even when the restrictor of the universal quantifier in a universal alternative is contextually known to be empty. The crucial evidence consists of a hitherto unnoticed oddness asymmetry between formally analogous existential sentences with reference failure NPs. I conclude (...) that the generation of mismatching scalar implicatures does not require contextual access. (shrink)

Arien Mack and Irvin Rock make the radical claim that there is no conscious perception of the visual world without attention to it.

Likert-scale surveys are frequently used in cross-cultural studies on leadership. Recent publications using digital text algorithms raise doubt about the source of variation in statistics from such studies to the extent that they are semantically driven. The Semantic Theory of Survey Response (STSR) predicts that in the case of semantically determined answers, the response patterns may also be predictable across languages. The Multifactor Leadership Questionnaire (MLQ) was applied to 11 different ethnic samples in English, Norwegian, German, Urdu and Chinese. Semantic (...) algorithms predicted responses significantly across all conditions, although to varying degree. Comparisons of Norwegian, German, Urdu and Chinese samples in native versus English language versions suggest that observed differences are not culturally dependent but caused by different translations and understanding. The maximum variance attributable to culture was a 5% unique overlap of variation in the two Chinese samples. These findings question the capability of traditional surveys to detect cultural differences. It also indicates that cross-cultural leadership research may risk lack of practical relevance. (shrink)
