The paper proposes a way of bridging the gapbetween physical processes in the brain and the ''''felt''''aspect of sensory experience. The approach is based onthe idea that experience is not generated by brainprocesses themselves, but rather is constituted by theway these brain processes enable a particular form of''''give-and-take'''' between the perceiver and theenvironment. From this starting-point we are able tocharacterize the phenomenological differences betweenthe different sensory modalities in a more principledway than has been done in the past. We are also (...) ableto approach the issues of visual awareness andconsciousness in a satisfactory way. Finally weconsider a number of testable empirical consequences,one of which is the striking prediction of thephenomenon of ''''change blindness''''. (shrink)

Many current neurophysiological, psychophysical, and psychological approaches to vision rest on the idea that when we see, the brain produces an internal representation of the world. The activation of this internal representation is assumed to give rise to the experience of seeing. The problem with this kind of approach is that it leaves unexplained how the existence of such a detailed internal representation might produce visual consciousness. An alternative proposal is made here. We propose that seeing is a way of (...) acting. It is a particular way of exploring the environment. Activity in internal representations does not generate the experience of seeing. The out- side world serves as its own, external, representation. The experience of seeing occurs when the organism masters what we call the gov- erning laws of sensorimotor contingency. The advantage of this approach is that it provides a natural and principled way of accounting for visual consciousness, and for the differences in the perceived quality of sensory experience in the different sensory modalities. Sev- eral lines of empirical evidence are brought forward in support of the theory, in particular: evidence from experiments in sensorimotor adaptation, visual “filling in,” visual stability despite eye movements, change blindness, sensory substitution, and color perception.

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.

The most important clarification we bring in our reply to commentators concerns the problem of the “explanatory gap”: that is, the gulf that separates physical processes in the brain from the experienced quality of sensations. By adding two concepts (bodiliness and grabbiness) that were not stressed in the target article, we strengthen our claim and clarify why we think we have solved the explanatory gap problem, – not by dismissing qualia, but, on the contrary, by explaining why sensations have a (...) “feel” and why “feels” feel the way they do. We additionally clarify our views on: internal representations (we claim internal representations cannot explain why sensation has a feel), on behaviorism (we are not behaviorists), on perception and action (we believe there can be perception without action), and on the brain (we believe the brain does do something important in perception).

Call u the triplet of cone quantum catch for the light that is incident on a surface, and v the triplet of cone quantum catch for the light that is reflected off that surface. Philipona &O'Regan (2006) present results from numerical calculations showing that: 1. each surface can be associated with a 3 by 3 matrix A such that the relation v = A u to a very high degree of accuracy for any natural illuminant, 2. the vast (...) majority of such matrices associated with Munsell chips have three real eigenvalues, 3. Munsell chips that are most often given a name in the World Color Survey are chips whose associated matrices have a singular configuration of eigenvalues, as measured by a "singularity index". The conclusion of the paper is that this striking coincidence lends credence to the idea that data about color naming derive from facts about natural lights, surface reflexion properties, and human photopigments, rather than from facts about neural pathways or cortical representations.

Word recognition performance varies systematically as a function of where the eyes fixate in the word. Performance is maximal with the eye slightly left of the center of the word, and decreases drastically to both sides of this 'Optimal Viewing Position'. While manipulations of lexical factors have only marginal effects on this phenomenon, previous studies have pointed to a relation between the viewing position effect and letter legibility: When letter legibility drops, the viewing position effect becomes more exaggerated. To further (...) investigate this phenomenon, we improved letter legibility by magnifying letter size in a way that was proportional to the.. (shrink)

Observers inspected normal, high quality color displays of everyday visual scenes while their eye movements were recorded. A large display change occurred each time an eye blink occurred. Display changes could either involve "Central Interest" or "Marginal Interest" locations, as determined from descriptions obtained from independent judges in a prior pilot experiment. Visual salience, as determined by luminance, color, and position of the Central and Marginal interest changes were equalized. -/- The results obtained were very similar to those obtained in (...) prior experiments showing failure to detect changes occurring simultaneously with saccades, flicker, or “mudsplashes” in the visual scene: Many changes were very hard to detect, and Marginal Interest changes were harder to detect than Central Interest changes. -/- Analysis of eye movements showed, as expected, that the probability of detecting a change depended on the eye’s distance from the change location. However a surprising finding was that both for Central and Marginal Interest changes, evenwhen observers were directly fixating the change locations (within 1 degree),more than 40% of the time they still failed to see the changes. It seems that looking at something does not guarantee you “ see” it. (shrink)

The target article appeals to recent empirical data to support the idea that there is more to phenomenality than is available to access consciousness. However, this claim is based on an unwarranted assumption, namely, that some kind of cortical processing must be phenomenal. The article also considerably weakens Block's original distinction between a truly nonfunctional phenomenal consciousness and a functional access consciousness. The new form of phenomenal consciousness seems to be a poor-man's cognitive access.

Overview. Consciousness is often considered to have a "hard" part and a not-so-hard part. With the help of work in artificial intelligence and more recently in embodied robotics, there is hope that we shall be able solve the not-so-hard part and make artificial agents that understand their environment, communicate with their friends, and most importantly, have a notion of "self" and "others". But will such agents feel anything? Building the feel into the agent will be the "hard" part.

Following arguments put forward in my book (Why red doesn’t sound like a bell: understanding the feel of consciousness. Oxford University Press, New York, USA, 2011), this article takes a pragmatic, scientist’s point of view about the concepts of consciousness and “feel”, pinning down what people generally mean when they talk about these concepts, and then investigating to what extent these capacities could be implemented in non-biological machines. Although the question of “feel”, or “phenomenal consciousness” as it is called by (...) some philosophers, is generally considered to be the “hard” problem of consciousness, the article shows that by taking a “sensorimotor” approach, the difficulties can be overcome. What remains to account for are the notions of so-called “access consciousness” and the self. I claim that though they are undoubtedly very difficult, these are not logically impossible to implement in robots. (shrink)

When looking at a scene, observers feel that they see its entire structure in great detail and can immediately notice any changes in it. However, when brief blank fields are placed between alternating displays of an original and a modified scene, a striking failure of perception is induced: identification of changes becomes extremely difficult, even when changes are large and made repeatedly. Identification is much faster when a verbal cue is provided, showing that poor visibility is not the cause of (...) this difficulty. Identification is also faster for objects mentioned in brief verbal descriptions of the scene. These results support the idea that observers never form a complete, detailed representation of their surroundings. In addition, results also indicate that attention is required to perceive change, and that in the absence of localized motion signals it is guided on the basis of high-level interest. (shrink)

The sensorimotor theory of perceptual consciousness offers a form of enactivism in that it stresses patterns of interaction instead of any alleged internal representations of the environment. But how does it relate to forms of enactivism stressing the continuity between life and mind? We shall distinguish sensorimotor enactivism, which stresses perceptual capacities themselves, from autopoietic enactivism, which claims an essential connection between experience and autopoietic processes or associated background capacities. We show how autopoiesis, autonomous agency, and affective dimensions of experience (...) may fit into sensorimotor enactivism, and we identify differences between this interpretation and autopoietic enactivism. By taking artificial consciousness as a case in point, we further sharpen the distinction between sensorimotor enactivism and autopoietic enactivism. We argue that sensorimotor enactivism forms a strong default position for an enactive account of perceptual consciousness. (shrink)

When brief blank fields are placed between alternating displays of an original and a modified scene, a striking failure of perception is induced: the changes become extremely difficult to notice, even when they are large, presented repeatedly, and the observer expects them to occur (Rensink,O'Regan, & Clark, 1997). To determine the mechanisms behind this induced "change blindness", four experiments examine its dependence on initial preview and on the nature of the interruptions used. Results support the proposal that representations (...) at the early stages of visual processing are highly volatile, and that focused attention is needed to stabilize them sufficiently to support the perception of change.

For some time, the role of culture in language education within schools, universities and professional communication has received increasing attention. This article identifies two aporias in the discourse of intercultural communication : first, that it contains an unstated movement towards a universal consciousness; second, that its claims to truth are grounded in an implicit appeal to a transcendental moral signified.These features constitute IC discourse as ‘totality’, or as ‘metaphysics of presence’.The article draws on the work of Levinas ; and Derrida (...) to propose more considered ethical grounds for intercultural praxis. Contra a Hegelian impetus towards universal consciousness,we posit an irreducible distance and separation between the self and other. In so doing, not only are we able to supersede the field’s implicit appeal to the transcendental as a source of truth but also to counter perceptibly ‘exorbitant’ claims and actions of the intercultural other. In this vein, the article proposes a discourse ethics of responsibility by which it still becomes possible for a critical intercultural praxis to make value judgements and to take potentially transformative action vis-à-vis cultural acts that challenge the limits of intercultural tolerance and hospitality.

Traditionally, the “Imagery Debate” has opposed two main camps: depictivism and descriptivism. This debate has essentially focused on the nature of the internal representations thought to be involved in imagery, without addressing at all the question of action. More recently, a third, “embodied” view is moving the debate into a new phase. The embodied approach focuses on the interdependence of perception, cognition and action, and in its more radical line this approach promotes the idea that perception is not a process (...) involving internal world-models. The anti-representationalist version of the embodied paradigm covers, among others that we shall not discuss here, two quite different positions, namely the enactive approach and sensorimotor theory. Up to now these two anti-representationalist accounts have generally been confounded. In this paper we will argue that despite some important commonalities, enactive and sensorimotor accounts come with distinctive theoretical traits with regard to their approach to imagery. These become manifest when critically examining the role they assign to sensorimotor engagements with the world. We shall argue that enactive and sensorimotor approaches are different in their understanding of the role of embodied action, and these different notions of embodiment lead to different explanatory accounts of perception and imagery. We propose that, due to existing ambiguities in enactivism, the sensorimotor theory is a better framework for a skill-based approach to imagery. (shrink)

We address the thesis recently proposed by Andy Clark, that skill-mediated access to modality implies phenomenal feel. We agree that a skill theory of perception does indeed offer the possibility of a satisfactory account of the feel of perception, but we claim that this is not only through explanation of access to modality but also because skill actually provides access to perceptual property in general. We illustrate and substantiate our claims by reference to the recently proposed 'sensorimotor contingency' theory of (...) visual awareness. We discuss why this theory offers a distinctively attractive access-based approach to perceptual consciousness because it 'dereifies' experience and permits otherwise problematic aspects of phenomenal perceptual consciousness to be explained. We suggest our approach thus offers the prospect of 'naturalizing phenomenology'. (shrink)

This paper looks at two puzzles raised by the phenomenon of inattentional blindness. First, how can we see at all if, in order to see, we must first perceptually attend to that which we see? Second, if attention is required for perception, why does it seem to us as if we are perceptually aware of the whole detailed visual field when it is quite clear that we do not attend to all that detail? We offer a general framework for thinking (...) about perception and perceptual consciousness that addresses these questions and we propose, in addition, an informal account of the relation between attention and consciousness. On this view, perceptual awareness is a species of attention. (shrink)

Minorities comprise a tiny fraction of media owners, and continued media consolidation exacerbates existing disparities. This article examines this problem by integrating the work of Jurgen Habermas and Jacques Ellul. These theorists identify a common concern—described alternately as technicization and colonization—involving homogenization of content, loss of localism, and decreased ownership diversity. In different ways, each acknowledges the possibility that social action can make a difference. Habermas' discourse ethics provides a normative foundation for arguing on behalf of ownership diversity and policy (...) reform. Though Ellul is skeptical of institutional reform, he offers a complementary vision of concrete action on the part of local, independent community groups. While their solutions are different, we argue that both are necessary. Media reform efforts must incorporate both Habermasian and Ellulian approaches by supplementing federal regulatory reform with independent grassroots activism. A combination of such efforts is essential to the movement's success. (shrink)

This article leverages interview data from students of Chinese who enrolled at a UK university but pursued a period of study abroad in China, aiming to delve into their negotiation of language identities during their overseas experience. By employing Block’s structural model in our discourse analysis, this research reveals the dynamic interplay between agency and structure, shedding light on the intricate process of language learning and identity formation. The findings underscore that structural contexts are integral to shaping students’ agency, highlighting (...) specific structural spheres that pose challenges to their development of Chinese language and multilingual identities. These spheres encompass the linguistic and cultural dominance of English as well as Chinese hospitality practices. Rooted in their habitus, participants’ preconceived notions of the Chinese language and cultural aspects influence their journey, yielding either positive or negative impacts. Furthermore, participants’ backgrounds and prior language learning experiences significantly contribute to their identity development. In advocating for a comprehensive approach, this study emphasises the integration of both agency and structural contexts as necessary to fully comprehend the intricate process of identity development.

This paper presents a longue durée account of the discursive emergence of ‘the market'. It seeks to develop understanding of the ‘crisis system' by showing that the crises of the present have their origins earlier than some critical realist scholars have suggested and can be better understood by the theorization of the generative mechanisms that emerged from the economic and political chaos of the early 1600s. Critical discourse analysis (CDA) is employed to show that in the context of the emergence (...) of capitalism in England, these generative mechanisms resulted in the meaning of the word ‘market’ slipping loose of the geo-spatial semiotic bounds by which it had commonly been delineated – i.e. as a physical space in a town or city where goods were bartered or sold – and being re-semioticised to refer to abstract space where all acts of capitalist economic exchange, including those impacting upon the natural world, take place.

Infants’ ability to monitor “sensorimotor contingencies,” i.e., the sensory effects of their own actions, is an important mechanism underlying learning. One method that has been used to investigate this is the “mobile paradigm,” in which a mobile above an infant’s crib is activated by motion of one of the infant’s limbs. Although successfully used in numerous experiments performed in infants’ homes to investigate memory and other types of learning, the paradigm seems less robust for demonstrating sensitivity to sensorimotor contingencies when (...) used in the laboratory. One purpose of the present work was to show that certain changes to the mobile paradigm would make it easier for infants to show their sensitivity to the contingency in the lab. In particular, we used proximal stimulation on infants’ wrists instead of the usual mobile, and our stimulation was coincident with the limbs that caused it. Our stimulation was either on or off, i.e., not modulated by the amount the infant moved. Finally, we used a “shaping” procedure to help the infant discover the contingency. In addition to these changes in the paradigm, by analyzing infants’ limb activity at 10-s resolution instead of the usual 1-min resolution, we were able to show that infants’ sensitivity to the contingency became apparent already within the first minute of establishment of the contingency. Finally, we showed how two alternate measures of sensitivity to contingency based on probability of repeated movements and on “stop and go” motion strategies may be of interest for future work.

This essay examines Newman’s life-long campaign against the errors of liberal religion, particularly its “anti-holiness” principle that rejects the Christian commitment to the pursuit of sanctity. In both his Anglican and Roman Catholic writings, Newman attacked the “anti-holiness” principle’s underlying presuppositions, particularly (1) its naturalistic anthropology, (2) its “anthropocentric horizon of discourse,” (3) its rejection of ascetic discipline in religious formation, and (4) its tendency to accept uncritically what is intellectually novel.

This book analyzes the philosophical foundations of sensorimotor theory and discusses the most recent applications of sensorimotor theory to human computer interaction, child's play, virtual reality, robotics, and linguistics. -/- Why does a circle look curved and not angular? Why doesn't red sound like a bell? Why, as I interact with the world, is there something it is like to be me? These are simple questions to pose but more difficult to answer. An analytic philosopher might respond to the first (...) by merely observing, ``if we ponder the concept `circle' we find that it is the essence of a circle to be round''; but where does this definition come from? Was it set in stone by the gods, the divine arbiters of circle-ness (red-ness and conscious-ness)?

The thought of G. W. F. Hegel has had a deep and lasting influence on a wide range of philosophical, political, religious, aesthetic, cultural and scientific movements. But, despite the far-reaching importance of Hegel's thought, there is often a great deal of confusion about what he actually said or believed. This is an invaluable introduction for philosophical beginners and a useful reference source for more advanced scholars and researchers.

In lieu of an abstract, here is a brief excerpt of the content:BALTHASAR AND ECKHART: THEOLOGICAL PRINCIPLES AND CATHOLICITY CYRILO'REGAN Yale University New Haven, Connecticut Or pleas'd to wound, and yet afraid to strike, Just hint a Fault, and hesitate Dislike; Alike reserv'd to blame or to commend, A tim'rous Foe and a suspitious Friend 1 THE TENDENCY to avoid exclusion is a mark of the thought of Hans Urs von Balthasar. It represents an identifying habit, an incorrigible (...) feature of style and sensibility. His texts in which theologians, philosophers, poets, dramatists, and saints are christianly praised give testimony to a catholicity that barely brooks limits. Not only in true Gospel fashion are a multitude invited to the eschatological banquet, they constitute the vast medium of tradition, in which Maximus the Confessor rubs shoulders with Plato, in the company of Claudel, Calderon, and Therese of Lisieux. At different times Balthasar thinks of the tradition as one huge symphony in which notes sound only to be transcended and as a conversation between particular perspectives on the great mystery of redemption, no one of which is final and which meet only in the infinity of their object. The decision for plurality and variety in the tradition certainly validates difference and counts against its reduction.2 Yet at the same time tradition, precisely as a matter of variety, exhibits a measure of coherence or concordance that pro1 These couplets are from Alexander Pope's poem Atticus.

Oakes, S.J. (San Francisco: Ignatius Press, 1992), pp. 39, 187, 251. 203 204 CYRILO'REGAN hibits difference from becoming truly excessive. It is this prohibition of excessive difference in Balthasar's reading of tradition that I would like to examine here. I take as my case study of Balthasar's rhetoric of reading his conflicted response to Meister Eckhart, about whose inclusion in the Christian tradition Balthasar expresses no doubts, yet whose theological message is such as to cause anxiety. We shall occupy ourselves in this paper with the way in which Eckhart's nonnegotiable inclusion within the tradition serves to repress the account of those features that present a fundamental challenge, that represent difference that would make the Christian field radically heterogeneous. In the first two sections, focusing mainly on the fifth volume of The Glory of the Lord (=GL),3 I shall offer outlines of both the positive and negative contributions Eckhart is deemed to have made to the theological tradition. Though I do not wish to give the impression of Scholastic pro and contra, Balthasar's positive remarks being imbricated with the negative and vice versa, it will be suggested that the elements adduced in both cases constitute mirror images of each other. Balthasar takes a bifocal, though not stereoscopic, view of a group of five elements: aesthetic disposition, the sameness of Being and God, the whylessness of the divine, Gelassenheit, and Gottesgeburt. This group is in effect read twice, once in a way that affirms and confirms Eckhart's unproblematic inclusion in the tradition (section 1), and again in a way that, in the light of basic Christian principles, raises serious questions about such inclusion (section 2). In a final section the question is raised whether the conflict in interpretation suggests a deeper underlying conflict between Balthasarian commitment to Catholic theological principles and catholicity.

When comparing the roles of the lightning strike and the dry climate in causing the forest fire, one might think that the lightning strike is more of a cause than the dry climate, or one might think that the lightning strike completely caused the fire while the dry conditions did not cause it at all. Psychologists and philosophers have long debated whether such causal judgments are graded; that is, whether people treat some causes as stronger than others. To address this (...) debate, we first reanalyzed data from four recent studies. We found that causal judgments were actually multimodal: although most causal judgments made on a continuous scale were categorical, there was also some gradation. We then tested two competing explanations for this gradation: the confidence explanation, which states that people make graded causal judgments because they have varying degrees of belief in causal relations, and the strength explanation, which states that people make graded causal judgments because they believe that causation itself is graded. Experiment 1 tested the confidence explanation and showed that gradation in causal judgments was indeed moderated by confidence: people tended to make graded causal judgments when they were unconfident, but they tended to make more categorical causal judgments when they were confident. Experiment 2 tested the causal strength explanation and showed that although confidence still explained variation in causal judgments, it did not explain away the effects of normality, causal structure, or the number of candidate causes. Overall, we found that causal judgments were multimodal and that people make graded judgments both when they think a cause is weak and when they are uncertain about its causal role. (shrink)

Counterfactual theories propose that people’s capacity for causal judgment depends on their ability to consider alternative possibilities: The lightning strike caused the forest fire because had it not struck, the forest fire would not have ensued. To accommodate a variety of psychological effects on causal judgment, a range of recent accounts have proposed that people probabilistically sample counterfactual alternatives from which they compute a graded measure of causal strength. While such models successfully describe the influence of the statistical normality (i.e., (...) the base rate) of the candidate and alternate causes on causal judgments, we show that they make further untested predictions about how normality influences people’s confidence in their causal judgments. In a large (N = 3,020) sample of participants in a causal judgment task, we found that normality indeed influences people’s confidence in their causal judgments and that these influences were predicted by a counterfactual sampling model in which people are more confident in a causal relationship when the effect of the cause is less variable among imagined counterfactual possibilities.
