It is natural to assume that the fine-grained and highly accurate spatial information present in visual experience is often used to guide our bodily actions. Yet this assumption has been challenged by proponents of the Two Visual Systems Hypothesis , according to which visuomotor programming is the responsibility of a “zombie” processing stream whose sources of bottom-up spatial information are entirely non-conscious . In many formulations of TVSH, the role of conscious vision in action is limited to “recognizing (...) objects, selecting targets for action, and determining what kinds of action, broadly speaking, to perform” . Our aim in this study is to show that the available evidence not only fails to support this dichotomous view but actually reveals a significant role for conscious vision in motor programming, especially for actions that require deliberate attention.

This paper examines Milner and Goodale’s hypothesis about the two visual streams and raises the questions of whether properties in egocentric space (commonly associated with the vision-for-action, or "dorsal," stream) can be part of the phenomenal content of perceptual experience, or only properties in allocentric space (commonly associated with the vision-for-perception, or "ventral," stream) can play this role, and how (if at all) properties in egocentric space differ from properties in allocentric space. These questions are reminiscent of (...) issues raised by Christopher Peacocke's "equal-sized trees" case: if you are looking at equal-sized trees on the side of a road, the trees will phenomenally look to you to be equally tall. But it is also true that a tree will take up more of the space in your visual field the closer it is to you. So, the equal-sized trees will also phenomenally look to you to have different heights. Your (visual) perceptual experience is not illusory. That is, the trees veridically look to you to have the same height, and they also veridically look to you to have different heights. Call the sort of issue raised here the "problem of dual looks." I provide a solution to the problem of dual looks that helps shed light on whether properties in egocentric space can be part of the phenomenal content of perceptual experience, and how (if at all) properties in egocentric space differ from properties in allocentric space.

Our eyes, bodies, and perspectives are constantly shifting as we observe the world. Despite this, we are very good at distinguishing between self-caused visual changes and changes in the environment: the world appears mostly stable despite our visual field moving around. This, it seems, also occurs when we are dreaming. As we visually investigate the dream environment, we track moving objects with our dream eyes, examine objects, and shift focus. These movements, research suggests, are reflected in the rapid movements or (...) saccades of our sleeping eyes. Do we really see the dream world in the same way that we see the real world? If we do, how could dreaming, usually assumed to be mind-generated hallucinations, replicate such an experience? This problem would be deflated if dreams are not hallucinations at all, but rather imagination, illusion or simply unrealistic. I argue that imagination and illusion views do not satisfactorily explain away the problem of vision and action in sleep. The imagination model is not a complete description of dreaming that is consistent with empirical research, and it is unlikely that the visual dream world is an illusion. Given that the dreaming visual experience is most likely active, hallucinatory, and at times a realistic world simulation, there are important implications for our understanding of visual perception and its relationship to movement. Evidence suggests that our dream eyes investigate the dream world as our waking eyes investigate the waking world. If changes to the unconsciously generated dream environment are perceived as external and unintentional while dream body movements are perceived as self-generated and intentional, current theory of visual perception may have to be expanded to account for how the dreaming mind generates a stable world in which we track and visually explore mind-generated objects.

Empirical work and philosophical analysis have led to widespread acceptance that vision for action, served by the cortical dorsal stream, is unconscious. I argue that the empirical argument for this claim is unsound. That argument relies on subjects’ introspective reports. Yet on biological grounds, in light of the theory of primate cortical vision, introspection has no access to dorsal stream mediated visual states. It is thus wrongly assumed that introspective reports speak to absent phenomenology in the dorsal (...) stream. In light of this, I consider a different conception of consciousness’s relation to agency in terms of access. While theoretical reasons suggest that the inaccessibility of the dorsal stream to conceptual report is evidence that it is unconscious, this position begs important questions. I propose a broader notion of access in respect of the guidance of intentional agency and not, narrowly, conceptual report (Note: this paper contradicts my earlier paper, "The Case for Zombie Agency").

David Milner and Melvyn Goodale’s dissociation hypothesis is commonly taken to state that there are two functionally specialized cortical streams of visual processing originating in striate (V1) cortex: a dorsal, action-related “unconscious” stream and a ventral, perception-related “conscious” stream. As Milner and Goodale acknowledge, findings from blindsight studies suggest a more sophisticated picture that replaces the distinction between unconscious vision for action and conscious vision for perception with a tripartite division between unconscious vision for (...) class='Hi'>action, conscious vision for perception, and unconscious vision for perception. The combination excluded by the tripartite division is the possibility of conscious vision for action. But are there good grounds for concluding that there is no conscious vision for action? There is now overwhelming evidence that illusions and perceived size can have a significant effect on action (Bruno & Franz, 2009; Dassonville & Bala, 2004; Franz & Gegenfurtner, 2008; McIntosh & Lashley, 2008). There is also suggestive evidence that any sophisticated visual behavior requires collaboration between the two visual streams at every stage of the process (Schenk & McIntosh, 2010). I nonetheless want to make a case for the tripartite division between unconscious vision for action, conscious vision for perception, and unconscious vision for perception. My aim here is not to refute the evidence showing that conscious vision can affect action but rather to argue (a) that we cannot gain cognitive access to action-guiding dorsal stream representations, and (b) that these representations do not correlate with phenomenal consciousness. This vindicates the semi-conservative view that the dissociation hypothesis is best understood as a tripartite division. (shrink)

This article suggests that ?evolutionary vision,? the unifying paradigm of physical, biological, and sociocultural evolution, needs to be fully embodied and deeply experienced in the human being, and that this can be effected by the experience at the heart of the ?perennial wisdom tradition,? 1 that is, that of ?non-dual perception.?

According to an influential view, the detection of action possibilities and the selection of a plan for action are two segregated steps throughout the processing of visual information. This classical approach is committed with the assumption that two independent types of processing underlie visual perception: the semantic one, which is at the service of the identification of visually presented objects, and the pragmatic one which serves the execution of actions directed to specific parts of the same objects. However, (...) as our knowledge of vision has improved over the years, this established view has turned out to be only an approximation. This paper sets out the details of a non-modularist approach to visual perception of action possibilities and explains how to resist the lure of cognitive segregation. (shrink)

The central problem of the ‘normativity of law’ concerns how legal rules or directives give us reasons for actions. The core of this question is how something that is external to the agent, such as legal rules or directives, can be ‘part of the agent’, and how they can guide the agent in performing complex actions (such as legal rule-following) that persist over time. David Enoch has denied that the normativity of law poses any interesting challenge to theories of law. (...) He argues that law provides reasons for actions in terms of what he calls triggering-reasons and he advances the view that because there are many circumstances in which reasons are triggered, law does not pose a special challenge. According to Enoch, once we understand the way that triggering reasons operate, we can understand how legal rules and directives provide us with reasons for actions. In §II of this paper, I set the stage for the debate and establish a set of principles that emerge from the common sense of view of reasons for actions and argue that any theory of reasons for action should provide a coherent explanation of these key principles. I focus on the idea that a satisfactory account of reasons for action should also explain reasons in actions. In §III I explain briefly the different theories of reasons for action and locate Enoch’s conception of reasons for action as triggering-reasons within this theoretical framework. In §IV I show that Enoch’s conception of reasons for actions does not explain some of the key features or principles that emerge from our common sense view of reasons for action and nor does it explain reasons in actions.Resumen:El problema central de la ‘normatividad del derecho’ versa sobre cómo las reglas o directrices jurídicas nos dan razones para la acción. El núcleo de esta cuestión reside en cómo algo que es externo al agente, tal como las reglas o directrices jurídicas, pueden ser ‘parte del agente’, y cómo pueden guiar a ese agente al llevar a cabo acciones complejas (tal como la obediencia de las reglas) que persisten en el tiempo. David Enoch ha negado que la normatividad del derecho presente algún reto interesante a las teorías del derecho. Arguye que el derecho provee razones para la acción en términos de lo que él llama razones detonantes (triggering-reasons) y propone la perspectiva de que, dado que hay muchas circunstancias bajo las cuales se detonan las razones, el derecho no plantea ningún reto especial. De acuerdo con Enoch, una vez que entendemos la manera en que operan las razones detonantes, podemos comprender cómo las reglas y directrices jurídicas nos proveen razones para la acción. En la sección II de este artículo, fijo el escenario para el debate y establezco una serie de principios que emergen de la visión de sentido común sobre las razones para las acciones, y sostengo que cual- quier teoría de las razones para la acción debería proporcionar una explicación coherente de estos principios clave. Me centro en la idea de que una concepción satisfactoria de las razones para la acción también debe- ría explicar las razones en las acciones. En la sección III, explico brevemente las diferentes teorías de las razones para la acción y ubico la concepción de Enoch de razones para la acción como razones detonantes (triggering-reasons) dentro de este marco teórico. En la sección IV muestro que la concepción de Enoch de razones para las acciones no explica algunas de las principales características o principios que emergen de nuestra visión de las razones para la acción basada en el sentido común, ni tampoco explica las razones en las acciones.

In visual information processing, two kinds of vision are distinguished: vision-for-perception related to the conscious identifi cation of objects, and vision-for-action that deals with visual control of movements. Neuroscience suggests that these two functions are performed by two separate brain neural systems - the ventral and dorsal pathways. Two experiments using behavioural measures were conducted with the objective of exploring any potential interaction between these two functions of vision. The aim was to combine in one (...) task methods allowing for the simultaneous capture of both perceptual global processing and affordance extraction and to check whether they infi uence each other. This aim was achieved by employing the paradigms of Navon and Tucker and Ellis. A compound fi gure was created made up of objects with handles that might or might not have orientation congruent between levels. The results revealed that while the affordance effect occurred every time, the Navon effect appeared only when subjects focused their attention on object elements responsible for inconsistence within compound fi gure. Most importantly, even when these two effects occurred at once, they had no effect on each other. Results from the study failed to confi rm the hypothesis about interaction and gives support to the view that vision-for-perception and vision-for-action tend to act as separate systems. (shrink)

The integration of multisensory information is an essential mechanism in perception and action control. Research in multisensory integration is concerned with how the information from the different sensory modalities, such as the senses of vision, hearing, smell, taste, touch, and proprioception, are integrated to a coherent representation of objects (for an overview, see e.g., Calvert, Spence and Stein, 2004). The combination of information from the different senses is central for action control. For instance, when you grasp for (...) a rubber duck, you can see its size, feel its compliance and hear the sound it produces. Moreover, identical physical properties of an object can be provided by different senses. You can both see and feel the size of the rubber duck. Even when you grasp for the rubber duck with a tool (e.g., with tongs), the information from the proximal hand, from the effective part of the distal tool and from the eyes are integrated in a manner to act successfully (for limitations of this integration see Sutter et al., 2013).Over the recent decade a surge of interest in multisensory integration and action control has been witnessed, especially in connection with the idea of a statistically optimized integration of multiple sensory sources. The human information processing system is assumed to adjust moment-by-moment the relative contribution of each sense’s estimate to a multisensory task. The sense’s contribution depends on its variance, so that the total varia... (shrink)

Western political thought during the past two centuries has been inspired by a dream of liberation that has left it prey to ideological visions of utopia.

This is the use of the tragic vision to emphasize the limits imposed upon political action by the existence of ineliminable tensions inherent in the human condition. What is of especial interest in this (...) connection is the attempt made by Nikolai Berdyaev to bring the tragic vision to bear on the reformulation of socialism in particular.

First published in 1995, The Visual Brain in Action remains a seminal publication in the cognitive sciences. It presents a model for understanding the visual processing underlying perception and action, proposing a broad distinction within the brain between two kinds of vision: conscious perception and unconscious 'online' vision. It argues that each kind of vision can occur quasi-independently of the other, and is separately handled by a quite different processing system. In the 11 years since (...) publication, the book has provoked considerable interest and debate - throughout both cognitive neuroscience and philosophy, while the field has continued to flourish and develop. -/- For this new edition, the text from the original edition has been left untouched, standing as a coherent statement of the authors' position. However, a very substantial epilogue has been added to the book in which Milner and Goodale review some of the key developments that support or challenge the views that were put forward in the first edition. The new chapter summarizes developments in various relevant areas of psychology, neuroscience and behaviour. It notably supplements the main text by updating the reader on the contributions that have emerged from the use of functional neuroimaging, which was in its infancy when the first edition was written. Neuroimaging, and functional MRI in particular, has revolutionized the field over the past 11 years by allowing investigators to plot in detail the patterns of activity within the visual brains of behaving and perceiving humans. The authors show how its use now allows scientists to test and confirm their proposals, based as they then were largely on evidence accrued from primate neuroscience in conjunction with studies of neurological patients.

This study explores the pathways from the aspiration to make a difference in the world to vision and action of social entrepreneurs. Based on the qualitative analysis of interviews with 23 individuals who have pioneered institutions and initiatives around corporate responsibility, we find two predominant pathways to vision. The deliberate path starts with aspiration and moves through purpose toward a relatively intentional vision that ultimately leads to, and is subsequently informed by, action. The emergent path (...) also begins with aspiration then moves directly to action and only retrospectively to a sense of a vision behind the actions taken. The emergent path, in which action precedes vision, is contrary to the dominant assumption that vision leads to action in an entrepreneurial context and may be further characterized as either inadvertent or developmental. In advancing a conceptual model of the vision–action or action–vision trajectories of social entrepreneurs, this study highlights the iterative nature of vision. This study also demonstrates the importance of considering formative experiences that contribute to the aspiration to make some kind of a difference in the world, a sense of purpose or intentions, and core values and beliefs in examining the ethicality of social entrepreneurship.

In lieu of an abstract, here is a brief excerpt of the content:Subtlety and Moral Vision in FictionEileen JohnIIn Martha Nussbaum’s work in Love’s Knowledge, the subtlety of literary fiction is given a prominent role in explaining literature’s moral influence. 1 Nussbaum argues that the subtlety displayed in certain works of literary fiction can help readers develop habits of perception such that they will perceive their actual moral world more finely and respond to it with a more nuanced range (...) of feeling. We are encouraged to perceive in this way both by encountering good examples of subtle, sensitive moral agents, in characters such as James’s Maggie Verver in The Golden Bowl, and by undergoing the perceiving, responding activity that can be required of a reader. The overarching assumption is that, as moral agents, we need finely-tuned perceptions and felt responses if we are to pick up on the morally relevant elements of our circumstances. We cannot count on finding bold, neat and regular moral patterns to follow; we are rather likely to find ourselves in a complex web of particular contexts, each demanding special moral attention. 2Nussbaum develops these claims in close conversation with the fiction and literary essays of Henry James. 3 Through examples from his novels, she illustrates and elaborates upon the ideal he points to in his essays, the ideal of “being finely aware and richly responsible,” of being a person “on whom nothing is lost.” 4 It seems quite appropriate to dwell on the works of Henry James as displaying—and as demanding from readers—a finer discrimination of elements of experience than we [End Page 308] ordinarily achieve. Discussing the “we” of James’s readers (and leading with a phrase of James’s), Nussbaum puts it: “‘Participators by a fond attention’ in the lives and dilemmas of his participants, we engage with them in a loving scrutiny of appearances. We actively care for their particularity, and we strain to be people on whom none of their subtleties are lost, in intellect and feeling” (p. 162). Having experienced this as readers, we are supposed to be better prepared to approach our own lives and dilemmas with equally scrupulous and caring attention.In general, I am less confident than Nussbaum about the connections between responsible reading of excellent fiction and the pursuit of a responsible moral life. The effects of intense appreciation of fictional moral contexts on real-life decision-making and action are probably quite indirect, requiring encouragement from real-life experiences, from practice with situations in which we have something at stake. But for the moment, I want to develop a suggestion that assumes, in agreement with Nussbaum, that one may take habits of perception learned as a reader and make them count in one’s larger moral life—albeit with reinforcement from one’s judgments and actions in that life.My suggestion involves seeing literary fiction as sometimes playing a subversive role with regard to subtlety. In saying that literary fiction can be “subversive” of subtlety, I am trying to capture the ways in which reading fiction can disrupt a working standard of subtlety. Works of fiction do not provide “normal” perceptual fields, and readers do not approach them with precisely “normal” perceptual habits, so, roughly stated, the reader-fiction interaction has plenty of potential for disrupting epistemic standards of subtlety, bluntness, opacity and so forth. I will illustrate two sorts of subversions of subtlety with an example from Toni Morrison’s The Bluest Eye. In one case, I will argue that the subversion of the standard of subtlety has moral import—this will provide a case to contrast with Nussbaum’s Jamesian examples.By bringing in an example from a non-Henry James novel, I hope to open up the discussion of moral vision in fiction to encompass epistemic qualities besides subtlety. It does not seem that the ideals of subtlety, fine awareness, and missing nothing can be the only epistemic qualities which serve to support literary works’ moral influence. 5 Nussbaum herself acknowledges that, by focusing on one literary paradigm, she pursues only one strand of a larger project (pp. 45–46). Since I here consider just one example from a different style of novel... (shrink)

According to Milner and Goodale’s dual visual systems (DVS) theory, a division obtains between visual consciousness and motor action, in that the visual system producing conscious vision (the ventral stream) is distinct from the one guiding action (the dorsal stream). That there would be this division is often taken (by Andy Clark and others) to undermine the folk view on how consciousness and action relate. However, even if this division obtains, this leaves open the possibility that (...) con- scious ventral information is often transmitted to the uncon- scious dorsal stream and then used to guide action, a possibility seeming to preserve a significant role for consciousness in action. This article assesses this possibility. In course of doing so, we will review those arguments recently having been made against the DVS view on how visual consciousness and action relate (ones due to, e.g., Briscoe and Schwenkler, or Schenk and McIntosh). What we will find is that, if we properly analyze the data upon which these arguments are based, we are still left with the impression that the DVS view is largely correct; i.e., it is only rarely that visual experience guides action.

Neuropsychological findings used to motivate the "two visual systems" hypothesis have been taken to endanger a pair of widely accepted claims about spatial representation in conscious visual experience. The first is the claim that visual experience represents 3-D space around the perceiver using an egocentric frame of reference. The second is the claim that there is a constitutive link between the spatial contents of visual experience and the perceiver's bodily actions. In this paper, I review and assess three main sources (...) of evidence for the two visual systems hypothesis. I argue that the best interpretation of the evidence is in fact consistent with both claims. I conclude with some brief remarks on the relation between visual consciousness and rational agency.

In 1969 the American avant-garde filmmaker Ken Jacobs gained wide recognition with a two-hour long interpretation of a 1905 silent short film. Ever since, the artist has kept on revisiting the same material, each time with a different technological approach. Originally hailed as a prime example of structural filmmaking, Jacobs’ more recent variations on the theme of Tom Tom the Piper’s Son beg for a broader understanding of his methods and the meanings implied. To gain a deeper insight in this (...) on-going mise-en-abyme, this essay expands comments by the artist himself with concepts taken from animation, media-archaeology and Warburg’s Mnemosyne atlas. Rereading a filmic text with minute attention, remediating it from an analogue to an electronic format, and reanimating the original action by adding a variety of intervals: all Jacobs’ strategies are aimed at demonstrating the afterlife of Tom Tom in a contemporary cultural context.

In this article, I attempt to describe how certain theoretical constructions of semiotics could be applied in educational theoretical work. First I introduce meaning as a basic concept of semiotics, thus also touching on concepts such as action, competence and causality. I am then able to define learning as a change of competences, and also refer to the pedagogical concept of learning i.e. Bildung, which can be roughly defined as valuable human learning. I then take up the problem of (...) education as pedagogical direction and communication. Finally, I conclude with some considerations on the famous Greimassian semiotic square. (shrink)

The concept of ‘world visions’, first elaborated in the early work of Georg Lukàcs, is used here as a tool whereby the similarities between Pascal’s Pensées and Kant’s critical philosophy are contrasted with the rationalism of Descartes and the empiricism of Hume. For Lucien Goldmann, a leading exponent of the most fruitful method of applying Marxist ideas to literary and philosophical problems, the ‘tragic vision’ marked an important phase in the development of European thought from rationalism and empiricism to (...) the dialectical philosophy of Hegel, Marx and Lukàcs. The book is not a collection of isolated essays on Kant, Pascal, Racine, the status of the legal nobility in seventeenth-century France and the exact nature of the religious movement known as Jansenism, but an attempt to formulate, by an examination of these different topics, a general approach to the problems of philosophy, of literary criticism, and of the relationship between thought and action in human society.

This is an edited transcript of a keynote paper given at IACR's 2021 Annual Conference. The paper outlines a critical realist approach to critique and illustrates its application to the contemporary economy. It argues that responsible, constructive critique depends on ethics, on causal explanation, and on the development of utopian visions. Utopias are tools, and concrete utopias are not visions of whole alternative ready-made societies, but rather partial models that can be built in practice as elements of the larger social (...) world. The argument is illustrated with three cases of digital utopianism, which help to demonstrate the practical challenges facing utopian schemes. Concrete utopias are a vehicle for combining our theoretical understandings of possibilities with an ethical analysis of needs in order to offer practical schemes for improving human flourishing.

The present proposal is an approach to the vision, cosmogony and philosophy of the Totonacapan people, and particularly with the inhabitants of the Totonacapan region in Veracruz Mexico, a town whose wisdom is manifested to this day, in the conservation of customs and traditions , as well as the hierarchy of collective desire that seeks health, well-being and peace in the region, are guides in the evolution of their cultural processes, where a closeness, respectful and deep with Mother Nature (...) stands out. This wisdom by the Council of Elders, transmitted to the new generations, by the Supreme Council of Totonacapan who seek share the basis to understand and conceive the current world, from the ancestral vision and cosmogony to identify their space, thought, spirituality and in the building your social context. In the Totonacapan region, the first pre-hispanic population concentrations were located around 1259 to 1311. Already by the year 1450, there is a record of incursions and the conquest of Totonaca territory, by the Mexica, establishing a relationship of domain and subordination. As a result of the presence of "Mexica" in the Totonaco territory, there was an imposition of customs and language, since in some areas they begin to speak in Nahuatl, resulting in the presence of a bilingualism (Nahuatl-Totonac) , situation that persists, until the encounter with the Spaniards in the year of 1519. At present, the Totonacapan region includes the area that extends from the Cazones River to the north, to the towns of Gutiérrez Zamora and Tecolutla, in the State of Veracruz in Mexico. 2 The importance of the document is that it constitutes an invitation to deepen and understand the vision of the inhabitants of Totonacapan, in the construction of their social context and their connection with nature, as part of an ancient culture, which creates and recreates their vision, in the search for the feeling of belonging and as an inheritance of the children of thunder (Tajin), as well as the need to preserve the benefits that nature itself offers them, seeking a peaceful and harmonious coexistence, in the social and environmental environment. However, the preservation of its history, tradition and philosophy of life, contrast with public policy strategies, particularly in the social sphere, and which are aimed at achieving economic development in the fight against multidimensional poverty and marginalization, all Once they have not incorporated into them, the feeling and living of the relationship between individual and nature, as the guiding axis, of the philosophy of the Totonacapan people. What is sustainability for the people of Totonacapan? What is social justice in the search for sustainability? And what is your concept of justice in sustainability and human development? From the vision and philosophy of the people of Totonacapan, as part of the history and tradition of the children of thunder "Tajin" and in whose worldview, he is responsible for regulating the rain, climate and life of the people of the region. How does the people of Totonacapan live and live in the face of the maelstrom of actions that, from public policy, that seek human development? How do you adjust, your way of life and how do you adapt to the requirements, which from the perspective of justice, are required to contribute to the objectives of the 2030 development agenda? This document is an effort to learn and recognize one of the most important millenary cultures in Mexico, in the construction of a more inclusive vision of the social development of the Totonacapan people, which invites us to reflect on the direction and scope of this response.

Visual modules can be viewed as expressions of a marked analytic attitude in the study of vision. In vision psychology, this attitude is accompanied by hypotheses that characterize how visual modules are thought to operate in perceptual processes. Our thesis here is that there are what we call “intrinsic reasons” for the presence of such hypotheses in a vision theory, that is, reasons of a deductive kind, which are imposed by the partiality of the basic terms in (...) the definition of a module, and by peculiar characteristics of those terms. Specifically, we discuss three hypotheses of functional attributes: successive stages in the action of modules, residual indeterminacy of their effects, and the role of prior constraints. For each of the three, we indicate its occurrence in perceptual psychology, explain corresponding intrinsic reasons, and illustrate such reasons with examples. (shrink)

I argue that conscious visual experience consists in a direct and noninferential grasp of the way one’s current perceptual contact with the environment poises one to pursue various intentional plans, goals and projects. I show that such a view of visual consciousness is supported by current work in cognitive neuroscience, affords a compelling account of colour perception, and suggests a way to bridge the ‘explanatory gap’ between consciousness and the language of the natural sciences. In chapter 1, I examine the (...) reasoning that leads to the appearance of an explanatory gap between the phenomenal and the physical in more detail, and set out the constraints on a solution that our discussion of the problem has imposed. I then sketch the two rival takes on the relationship between perception and action mentioned above – adjudicating between these two theories is the task of the next two chapters, and is a recurring theme throughout. Chapter 2 moves on to discuss some recent work in the neuropsychology of vision and what it might suggest about the functional role of conscious vision, and the first half of chapter 3 considers two puzzle cases concerning colour perception. Each of these discussions turns out to constitute a source of support for the actionspace view that visual perception consists in a grasp of the practical consequences of sensation, and the second half of chapter 3 sets out this view and responds to an initial range of questions and objections it might face. Chapter 4 illustrates our view via a discussion of colour perception, and chapter 5 discusses the type of grasp of practical consequences that is necessary for perceptual sensitivity to issue in conscious experience. By chapter 6, we are in a position to see how the action-space approach can help close the explanatory gap for phenomenal consciousness, and our final chapter sets out how I think this should be done. I conclude with a brief discussion of further questions and prospects for the action-space approach. (shrink)

The ennobling vision of modernity asserts that the benefits of identifying individual citizens as subjectivity are realized only when each subject is aware of the self as free in decisions and actions. Modernization through industrialization and urbanization has been seen as a means by which society can, through market contractual relationships, allow each citizen to become a self-determining subject. In Korean society this self-awakening has already set in and ought to deepen through dynamic economic growth. However, the authoritarian political (...) power combined by technocracy obstructs the emergence of mature subjectivity. This is what can be called a phenomenon of counter-modernization. Citizenship training through philosophical dialogue may find ways to resolve this impasse by reconceptualizing modernity’s goals and means in terms of enabling the potentiality inherent in subjectivity.

Is action-guiding vision cognitively penetrable? More specifically, is the visual processing that guides our goal-directed actions sensitive to semantic information from cognitive states? This paper critically examines a recent family of arguments whose aim is to challenge a widespread and influential view in philosophy and cognitive science: the view that action-guiding vision is cognitively impenetrable. I argue, in response, that while there may very well be top–down causal influences on action-guiding vision, they should not (...) be taken to be an instance of cognitive penetration. Assuming otherwise is to assign a computational role to the influencing states that they cannot perform. Although questions about cognitive penetrability are ultimately empirical, the issues addressed in this paper are largely philosophical. The discussion here highlights an important set of considerations that help better understand the relations between cognition, vision, and action. (shrink)

Gustavo Gutiérrez develops an account of human action or praxis that I--borrowing the language of Charles Taylor--label expressivist. Human action must be understood as expressing an underlying potential or impulse that only becomes real through expression in action. Gutiérrez's expressivism is fundamental to his view of the relationship between faith and love, his notion of three dimensions of liberation/salvation, and his understanding of the fundamental option as a yes or no in response to grace. Moreover, it supports (...) a valuable approach to community as defined more by shared actions than a shared tradition or narrative. The final section briefly indicates two limitations to Gutiérrez's vision--especially with regard to the conception of community--and suggests the direction that a constructive appropriation of his thought might take.

Increasing computational power and improving deep learning methods have made computer vision technologies pervasively common in urban environments. Their applications in policing, traffic management, and documenting public spaces are increasingly common (Ridgeway 2018, Coifman et al. 1998, Sun et al. 2020). Despite the often-discussed biases in the algorithms' training and unequally borne benefits (Khosla et al. 2012), almost all applications similarly reduce urban experiences to simplistic, reductive, and mechanistic measures. There is a lack of context, depth, and specificity in (...) these practices that enables semantic knowledge or analysis within urban contexts, especially within the context of using and occupying urban space. This paper will critique existing uses of artificial intelligence and computer vision in urban practices to propose a new framework for understanding people, action, and public space. This paper revisits Geertz's (1973) use of thick descriptions in generating interpretive theories of culture and activity and uses this lens to establish a framework to approach evaluating the varied uses of computer vision technologies that weigh meaning. By discussing cases of implemented examples of urban computer vision—from LinkNYC and Numina's urban measurements to the Detroit Police's use of DataWorks Plus's facial recognition technology—it proposes a framework for evaluating the thickness of the algorithm's conclusions against the computational method's complexity required to produce that outcome. Further, we discuss how the framework's positioning may differ (and conflict) between different users of the technology, from engineer to urban planner and policymaker, to citizen. This paper also discusses how the current use and training of deep learning algorithms and how this process limits semantic learning and proposes three potential methodologies toward gaining a more contextually specific, urban-semantic, description of urban space relevant to urbanists. This paper contributes to the critical conversations regarding the proliferation of artificial intelligence by challenging the current applications of these technologies in the urban environment by highlighting their failures within this context while also proposing an evolution of these algorithms that may ultimately make them sensitive and useful within this spatial and cultural milieu.

It is widely recognized that police performance may be hindered by psychophysiological state changes during acute stress. To address the need for awareness and control of these physiological changes, police academies in many countries have implemented Heart-Rate Variability biofeedback training. Despite these trainings now being widely delivered in classroom setups, they typically lack the arousing action context needed for successful transfer to the operational field, where officers must apply learned skills, particularly when stress levels rise. The study presented here (...) aimed to address this gap by training physiological control skills in an arousing decision-making context. We developed a Virtual-Reality breathing-based biofeedback training in which police officers perform deep and slow diaphragmatic breathing in an engaging game-like action context. This VR game consisted of a selective shoot/don’t shoot game designed to assess response inhibition, an impaired capacity in high arousal situations. Biofeedback was provided based on adherence to a slow breathing pace: the slower and deeper the breathing, the less constrained peripheral vision became, facilitating accurate responses to the in-game demands. A total of nine male police trainers completed 10 sessions over a 4-week period as part of a single-case experimental ABAB study-design. Results showed that eight out of nine participants showed improved breathing control in action, with a positive effect on breathing-induced low frequency HRV, while also improving their in-game behavioral performance. Critically, the breathing-based skill learning transferred to subsequent sessions in which biofeedback was not presented. Importantly, all participants remained highly engaged throughout the training. Altogether, our study showed that our VR environment can be used to train breathing regulation in an arousing and active decision-making context. (shrink)

In _Action in Perception _Alva No develops and presents a sensorimotor account of vision and of visual consciousness. According to such an account seeing (and indeed perceiving more generally) is analysed as a kind of skilful bodily activity. Such a view is consistent with the emerging emphasis, in both philosophy and cognitive science, on the critical role of embodiment in the construction of intelligent agency. I shall argue, however, that the full sensorimotor model faces three important challenges. The first (...) is to negotiate a path between two prima facie unsatisfactory readings of the central claim that conscious perceptual experience is constituted by knowledge of patterns of sensorimotor dependence. The second is to convince us that the sensorimotor contribution, in such cases, is actually constitutive of perceptual experience rather than merely causally implicated in the origination of such experience.² And the third is to respond to the important challenge raised by what I will dub 'sensorimotor summarizing' models of the relation between conscious experience and richly detailed sensorimotor routines. According to such models³ conscious perceptual experience only rather indirectly reflects the rich detail of our actual sensorimotor engagements, which are instead lightly sampled as a coarse guide, optimized for planning and reasoning, and geared and filtered according to current needs and purposes.

Physicist David Bohm and biochemist Ilya Prigogine began a dialogue that implied a deep, structuring, primordial harmony within life. In classical Chinese this harmony is referred to as Li, which also designates the elegant, natural pattern found in jade. This article emphasizes the ways that perception of primordial harmony gives way to a vision of possibility and to the creative intelligence and action necessary for meeting the challenges we face. Insights from Bohm, Prigogine, and others on releasing outmoded (...) thinking and actions are integrated with contemplative traditions, Eastern and Western philosophy, and pragmatic strategy making.

The term ‘cell’, in addition to designating fundamental units of life, has also been applied since the nineteenth century to technical apparatuses such as fuel and galvanic cells. This paper shows that such technologies, based on the electrical effects of chemical reactions taking place in containers, had a far-reaching impact on the concept of the biological cell. My argument revolves around the controversy over oxidative phosphorylation in bioenergetics between 1961 and 1977. In this scientific conflict, a two-level mingling of technological (...) culture, physical chemistry and biological research can be observed. First, Peter Mitchell explained the chemiosmotic hypothesis of energy generation by representing cellular membrane processes via an analogy to fuel cells. Second, in the associated experimental scrutiny of membranes, material cell models were devised that reassembled spatialized molecular processes in vitro. Cells were thus modelled both on paper and in the test tube not as morphological structures but as compartments able to perform physicochemical work. The story of cells and membranes in bioenergetics points out the role that theories and practices in physical chemistry had in the molecularization of life. These approaches model the cell as a ‘topology of molecular action’, as I will call it, and it involves concepts of spaces, surfaces and movements. They epitomize an engineer’s vision of the organism that has influenced diverse fields in today’s life sciences. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Rethinking Social Action through Music: The Search for Coexistence and Citizenship in Medellín’s Music Schools by Geoffrey BakerKim BoeskovGeoffrey Baker: Rethinking Social Action through Music: The Search for Coexistence and Citizenship in Medellín’s Music Schools (Cambridge, UK: Open Book Publishers, 2021)If indeed there exists, as Geir Johansen has proposed,1 a self-critical movement within the field of music education, Geoffrey Baker is undoubtedly one of its leading (...) figures. According to Johansen, the self-critical turn is characterized by an increasing number of music educators directing criticism toward music education itself by denouncing overly romantic visions of “the power of music” and scrutinizing how music educational practices are implicated in the propulsion of problematic social forces of inequality, oppression, and injustice. Baker’s widely read book from 2014, El Sistema: Orchestrating Venezuela’s Youth,2 thoroughly denounced the globally acclaimed Venezuelan ‘musical miracle’ as a myth. Based on extensive field work in Venezuela, Baker painstakingly dissected El Sistema as an archaic, morally, and pedagogically flawed model of music education veiled in the empty rhetoric of music as a tool of social redemption and documented how such models are ripe with opportunities for abuse, in every sad sense of the word.The continuation of Baker’s critical project is published in the form of a four-hundred-page book, entitled Rethinking Social Action Through Music. Baker presents the text as “a ‘post-El Sistema’ project”3 as it constitutes a departure [End Page 92] from his preoccupation with ‘The System’ toward potential alternatives to the Venezuelan model. He finds such an alternative in the Red (Red de Escuelas de Música de Medellín), a network of music schools in the Colombian city of Medellín, which figures as the center of attention in Baker’s institutional ethnography. However, even as the Colombian institution is invoked as a counterexample to its Venezuelan sibling, the Red is not held up for its ability to enact social change or display of innovative pedagogical principles. What Baker finds exemplary and worthy of investigation is the willingness he locates within the administrative layer of the Red to continuously engage in reflective work with regards to the tensions, conflicts, and pitfalls, as well as potentials of musical-social work. Particularly, Baker’s attention is directed to the decision-making processes and discussions among the leaders of the institution; how senior staff members adopt self-critical stances, how needs for institutional change are recognized, the recurring frictions between musical staff and members of the institution’s social team, and tensions between public statements expressing confidence in the program’s efficacy and internal conversations full of ambivalence and doubt.It is with reference to the reflexive processes of the Red that Baker conducts insightful and well-informed discussions of a range of themes relevant to music educators and scholars. Baker situates his analysis within the wider landscape of SATM (Social Action Through Music), which can roughly be understood as the field of musical practice emanating from the large socio-musical orchestral programs conceived in Latin America in the last decades of the 20th century and subsequently spread as ‘Sistema-inspired’ offspring throughout the globe in the beginning of the 21st century. Yet, the discussions found in this book are easily connected to pertinent themes of the philosophy and sociology of music education, such as the notion of artistic citizenship, decolonization, the political nature of music education, ‘the social’ in music education, to name a few. One of the striking qualities of this book is its ability to identify important issues in the local context of Medellín, extract the underlying mechanisms and through empirical examples unfold a much broader discussion of what social justice and social change might mean in the field of music education. Baker, originally educated as an ethnomusicologist, reflects on these topics with depth and nuance, underscoring the relevance of approaching these complex issues through ethnographic work, rather than basing such discussions solely on conceptual exploration.Appearing as a red line throughout the book is Baker’s insistence on foregrounding the ambiguity and ambivalence of musical-social work. In fact, his critical encounter with the field... (shrink)

What is the primary function of consciousness in the nervous system? The answer to this question remains enigmatic, not so much because of a lack of relevant data, but because of the lack of a conceptual framework with which to interpret the data. To this end, we have developed Passive Frame Theory, an internally coherent framework that, from an action-based perspective, synthesizes empirically supported hypotheses from diverse fields of investigation. The theory proposes that the primary function of consciousness is (...) well-circumscribed, serving the 'somatic nervous system[. For this system, consciousness serves as a frame that constrains and directs skeletal muscle output, thereby yielding adaptive behavior. The mechanism by which consciousness achieves this is more counterintuitive, passive, and “low level” than the kinds of functions that theorists have previously attributed to consciousness. Passive frame theory begins to illuminate (a) what consciousness contributes to nervous function, (b) how consciousness achieves this function, and (c) the neuroanatomical substrates of conscious processes. Our untraditional, action-based perspective focuses on olfaction instead of on vision and is 'descriptive' (describing the products of nature as they evolved to be) rather than 'normative' (construing processes in terms of how they should function). Passive frame theory begins to isolate the neuroanatomical, cognitive-mechanistic, and representational (e.g., conscious contents) processes associated with consciousness. (shrink)

The strong sensorimotor account of perception gives self-induced movements two constitutive roles in explaining visual consciousness. The first says that self-induced movements are vehicles of visual awareness, and for this reason consciousness ‘does not happen in the brain only’. The second says that the phenomenal nature of visual experiences is consists in the action-directing content of vision. In response I suggest, first, that the sense in which visual awareness is active should be explained by appeal to the role (...) of attention in visual consciousness, rather than self-induced movements; and second, that the sense in which perceptual consciousness does not happen in the brain only should be explained by appeal to the relational nature of perceptual consciousness, appeal to which also shows why links with action cannot exhaust phenomenal content.

A co-resident, my (...) friend from Latin America, makes this inquiry without even looking up, as he clicks nonchalantly through some Internet pages. I look at him and try to understand him within his context; he was born and raised in [End Page E6] what is traditionally considered a "resource-poor setting," but through talent, hard work, luck and privilege he was accepted into one of the best residency programs in one of the best U.S. hospitals. Unprepared, I give some anemic responses about social responsibility and global citizenship.He looks at his screen and clicks on a couple of links. Suddenly, he turns to me and exclaims, "I get it! You guys are going because then you can put your PWAB on your CV!" I give him a blank look.He stands and goes over to the dry erase board to write: "PWAB—Picture With an African Baby."I'm amused for a moment, and then suddenly hurt. What does this mean? Is he questioning our intentions, our moral resolve? I look over to his computer and see that he's been flipping through the "Global Health Residency" pages of all the local residency programs, or the Facebook pages of colleagues who have recently returned from work abroad. My hurt morphs into incredulity—all the pages have a picture of a beaming, healthy doctor holding a beautiful, newly happy, previously sick, African baby. And then, the code bell goes off, and the admissions start. Reflection time is over.Years later, now that I have become a junior faculty member within the same residency program, I divide my year between global health projects in rural Mexico and Guatemala, the classrooms of a U.S. medical school, and the patient rooms of a teaching hospital. The number of undergraduate and medical students who approach me because they want advice about how to work in global health is staggering; their emails fill my inbox and their faces grace my office hours. External observers have even compared the unprecedented rise of this type of interest to "a veritable tsunami," and we often take for granted that this is because the field is "inspiring" (Mallampati & Heintz, 201, p. 22). We still don't know, however, what all this inspiration becomes once it touches down on-site. For many students, the experience with talented mentors on-site opens up for them a life-long career that aims to address the greatest challenges of our day. The PWAB, however, implies that for an important number of other students, global health is becoming a social capital commodity: an edu-vacation, something to make your mother proud, win a mate, maybe even just another mandatory rotation needed to spice up the application for a career in a highly competitive subspecialty.If students are the future of this field, then the way that global health educators like myself manage this issue may ultimately determine the objectives and scope of countless potential projects hoping to help the billions of people barely surviving abject poverty. I have a career in global health that is more than a hobby because of the clear vision and strong leadership of my mentors and our university (Farmer, 2011). When I was hired as faculty, they worked with me to find the right full-time equivalent (FTE) split so that I could both make a living as an attending, and also still have time to teach, think, research, and manage a project abroad pro bono. But it's from this point that my question begins: once the students are inspired, and the investment made, what inspires good, sustained, pragmatic action in global health?A big part of the answer to this question will depend on how we define global health.

Since their introduction in Colombia in the '80s for Pablo Escobar’s extravagant zoo, hippos have become an ecological problem around the basin of the Magdalena River. This article proposes an ecosemiotic discourse analysis of different visions of nature enacted by stakeholders and public opinion around the management of hippos in Colombia. Concretely, we focus on three particular discourses and visions of nature: animalista, narco-cultural, and conservacionista. In this article, we present the relevant social and ecological context of Colombia, the visions (...) of nature theory and the impact of such visions on conservation measures regarding so-called invasive species; we describe and analyze the three visions of nature we center on, and present a computational analysis of discourse dynamics and controversies in Twitter between of such visions of nature; and we reflect on possible courses of action and recommendations about addressing the close interrelation of public discourses and ecosystem conservation by proposing an alternative view, based on the biosemiotic framework of semiocide, to the concept of invasive species.

In lieu of an abstract, here is a brief excerpt of the content:Visions of Damietta:St. Francis, Robert Grosseteste, and the Crusades, 1219–1253Rosamund M. Gammie (bio)A peculiar and under-explored event in Robert Grosseteste's (d. 1253) life is that of his supposed dream-vision in 1249, reported posthumously and in only one source, the Lanercost chronicle.1 The vision foreshadows the loss of Damietta in Egypt the following year, during the Seventh Crusade (1249–54) under the leadership of Louis IX. The parallels to (...) St. Francis's vision at Damietta in 1219 during the Fifth Crusade (1215–21) are immediately noticeable yet the vision has remained largely dismissed as an afterthought in the scholarship of Grosseteste. Considering that Grosseteste wrote, in 1236, what has been described by Michael Lower as "surely the best defence of the cross petition a crusader ever had," in addition to his association with the Franciscans and his relationship with Richard, earl of Cornwall, brother of Henry III and nephew of celebrated crusader Richard I and a (if not the) principal leader of the Baron's Crusade, it is surprising that there is no fuller account of his support for the movement; rather there are piecemeal references to certain acts of interference such as that noted by Lower.2 This paper seeks to establish Grosseteste's position on the crusades, in light of a thoroughly Franciscan influence, beginning with Damietta. [End Page 141]Robert Grosseteste and the FranciscansMuch has been written about the relationship between Robert Grosseteste and the early Franciscan movement in England.3 As Giles Gasper writes in a recent study of Grosseteste and the Franciscan school at Oxford, "Robert Grosseteste is well-known for his support for the Franciscan order, and his warm relations with many brothers of the English province."4 James McEvoy concludes in his examination of Grosseteste's affinity with the nascent movement that "there can be no doubt that Grosseteste was well acquainted with the personality and ideals of St. Francis, the circumstance of the Franciscans' foundation, and the nature of their vocation."5 Grosseteste's Letters are full of admiration for the Franciscans and involvement in their affairs, so much so that a clear and uncompromisingly affectionate relationship can be traced during the bishop's lifetime. Indeed, Grosseteste, in Letter 41, ca. 13 March, 1236, declares to Elias of Cortona, third minister of the Franciscan Order, that "there are no assistants I know of … so effective as your friars."6 The Friars themselves reciprocated their love for Grosseteste; the same letter states, "your sons, the Friars Minor in England, out of kindness in a special way embrace me tightly with arms of love." A letter from 1238 (Letter 58) to Pope Gregory IX asks for help in preserving the reputation of the Brothers, who "illuminate our whole land with the brilliant light of their preaching and teaching" with the warning that "the glory of such an important religious order will vanish and the masses will be scandalized in them."7 [End Page 142]The Dominican Brother Hubert perhaps best expresses the affection between the religious orders and Grosseteste, writing the celebratory Life of Grosseteste shortly after the bishop's death in 1253.8 According to Brother Hubert, Grosseteste was the "father and guardian" of both orders, whose presence "pleased him, as did their / Arrival, their multitude, and frequent conversation," and that just "as a mother to her new-born, he fostered, loved / Protected, fed, and valued them."9 Gasper continues, "English Franciscan historiography leaves no doubt as to the high esteem in which the order held Grosseteste from the mid-13th century onwards, honored in particular for his teaching and learning."10 Chosen personally by Agnellus of Pisa to teach the first Franciscans at Oxford, his influence cannot be underestimated. Indeed, there were Franciscan (and Dominican) contributions to the ultimately unsuccessful attempt to canonize the bishop; a ten-lined letter from Nicholas, guardian of the Greyfriars at Lincoln, penned on 26 June, 1289, extolls the exemplary actions of the bishop.11The relationship between Grosseteste and this first generation of Franciscans was one of mutual respect and love. What is harder to trace is Grosseteste's appreciation of St. Francis himself. When Servus Gieben asks... (shrink)

Vision is the main entrance for environmental input to the human brain. Even if vision is our most used sensory modality, its importance is not limited to environmental exploration. Rather it has strong links to motor competences, further extending to cognitive and social aspects of human life. These multifaceted relationships are particularly important in developmental age and become dramatically evident in presence of complex deficits originating from visual aberrancies. The present review summarizes the available neuropsychological evidence on the (...) development of visual competences, with a particular focus on the associated visuo-motor integration skills in health and disease. With the aim of supporting future research and interventional settings, the goal of the present review is to constitute a solid base to help the translation of neuropsychological hypotheses into straightforward empirical investigations and rehabilitation/training protocols. This approach will further increase the impact, ameliorate the acceptance, and ease the use and implementation of lab-derived intervention protocols in real-life situations. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Holocaust Visions: Surrealism and Existentialism in the Poetry of Paul CelanVéronique M. FótiHolocaust Visions: Surrealism and Existentialism in the Poetry of Paul Celan, by Clarise Samuels; x & 134 pp. Columbia, South Carolina: Camden House, 1993, $53.50.Samuels’s thesis is that Celan’s poetic work in its entirety can and should be understood as a comprehensive and unified philosophical system, in which each poem is assigned its place. This system (...) is not outlined in terms of its organizing principles, but rather in its topography of three superimposed layers. The top layer (which an empiricist would consider foundational) mirrors an “objective” reality and is informed by finehoned observation, whereas the middle layer constitutes an “ideological program” that “attempts to establish a socio-political value system” (p. 2), while the supporting bottom layer offers an “existentialist epistemology.”Despite her stress on systematicity (obsolete since Hegel), Samuels identifies surrealism (particularly the strand deriving from Breton) and existentialism as the formative influences on Celan’s poetics; and she carefully explores the interrelations of these movements of thought with the heritage of French symbolism, and with Dadaism and Marxism. She does not, however, use guiding concepts, such as “epistemology” or “ideology,” in any precise philosophical sense. By “epistemology” she seems to mean a fundamental concern for reality and truth, coupled with the belief that truth is accessible beyond [End Page 382] social constructions of meaning, whereas “ideology” is used in the various senses of revolutionary program, utopian vision, structure of ideas, or even just ideation (as in “On the ideological level, the Holocaust fulfills the surrealist intention of entering the individual’s subconscious,” p. 108).On the basis of her analyses of surrealist and existentialist thought, Samuels examines Celan’s poetry and poetics with a view to his search for an “alter reality” that would transcend, but not negate, the “Holocaust universe.” She first researches Celan’s syntactic structures, such as the “genitive phrase,” the elliptical sentence, or the fragmentation (and recombination) of words, to move on to a discussion of his tropes, which she arranges broadly into “representations of space, time, persons, and actions” (p. 39). Her discussion of Celan’s spatial tropes, particularly of his devastated imaginary landscapes and places of loss (unfortunately “space” and “place” are not distinguished), is especially compelling. It is further enriched, in the final chapter, which seeks to elucidate Celan’s notion of utopia and to locate utopia in art, by reference to the visual work of Tanguy, Ernst, and Magritte.The book as a whole is meticulously researched and includes extensive discussions of the secondary literature, with a slant toward Germanistik rather than philosophy, and with perhaps a particular debt to Marlies Janz. Its weakness is, in a way, tied to its strength: in her discussions of philosophical concepts and movements, Samuels seems to rely largely on (somewhat dated) secondary literature, so that her philosophical understanding is frequently a confused amalgam. For instance, she links Sartre’s in-itself to the Kantian noumenon (p. 20) and goes on to locate it, not only in the “universe,” but also “at the core of the human self,” so that the for-itself contrasts with it as a “superficial” construction, a sort of artifact that needs to be “controlled.” She assimilates the nihilating character of Sartrean consciousness to a “principle of nihilism” that supposedly characterizes existentialism, while nevertheless interpreting Sartre’s humanism as a turn toward “the eternal aspect” of mankind. Heidegger is cast as an existentialist in search of a literalized authenticity, while his critique of Sartrean humanism is simply ignored.In treating Celan’s poetry as systematically coherent and as, in some sense, ideological, Samuels not only disregards the striking stylistic changes that characterize its various phases, but she also does not try to unravel its intricate textual fabric of allusions (notably to Hölderlin and Trakl), to analyze textual structures such as the displaced re-inscription of the date (notably Büchner’s Jänner), or to respond to its unleashing of the semantic energies that lie latent beneath the surface of ordinary language. Sometimes she overlooks her own inchoate interpretive insights, as in her two discussions of parts of... (shrink)

Choking under pressure describes the phenomenon of people performing well below their expected standard under circumstances where optimal performance is crucial. One of the prevailing explanations for choking is that pressure increases the conscious attention to the underlying processes of the performer's task execution, thereby disrupting what would normally be a relatively automatic process. However, research on choking has focused mainly on the influence of pressure on motor performance, typically overlooking how it might alter the way that vision is (...) controlled when performing these motor actions. In this article we ask whether the visual component of expert motor-skill execution is susceptible to choking much like the motor component is thought to be. To do so, we draw heavily on empirical findings from studies of sporting expertise, in particular focussing on the role of gaze in three types of visually-guided actions: interceptive actions, aiming tasks, and anticipatory skill. For each of these skills we evaluate the nature of the expert advantage, discuss the role of consciousness in their control, examine the potential impact of pressure on task performance, and consider interventions designed to reduce the likelihood of choking when performing these tasks.

In lieu of an abstract, here is a brief excerpt of the content:The Journal of Aesthetic Education 37.4 (2003) 58-64 [Access article in PDF] Media Literacy Education in Art:Motion Expression and the New Vision of Art EducationThe Bauhaus, which established the foundation of modern design, has greatly influenced Japanese design and art education. It is a historical fact that the movement views "synthetic art" as an integration of the various fields and the integration of the art and machine technology (...) experimentally. However, the Bauhaus is not just of historical importance but continues to have an influence even in the integration of the art and electronic technology in today's "multimedia." In addition, it can be said that it is very much alive as "the digital Bauhaus" or "the electronic Bauhaus." 1 As we know, today's multimedia and the Internet give us a new life-environment, and expandthe possibility of expression in art. Therefore, current art education must examine how these new medias will be incorporated into the curriculum.In the cases of the photograph, video, or computer, an expression by the image media is added to the art course for the junior high school course of study. 2 Also in school art classes, image media was introduced, expanding the possibilities of self-expression through art. This result can be matched to the needs of the industrial world in Japan as well. As an educational practice, the content of this course of study is promising, even though someproblems must be solved, acquiring new equipment, re-educating the artteacher, and securing additional art school hours. The new content in art education can be summarized as follows:1. The motion picture (animation) which includes time and movement. Motion picture is asequence of continuous images, obviously different from the still images of painting. There are, of course, artworks that express motion or induce the viewer'seye movement. There are also kinetic artworks that do move, such as mobiles. Works of motion picture have, however, a fixed time shaft, and they are formed by the afterimage phenomenon. Thinking about the progress of time shaft is an indispensable element for the production. [End Page 58]2. The synchronism of image and sound. Because time is a factor in the visual expression, the works are compatible with music — the art of time. There is a synchronized relation between the motion picture and music. Image expression with multimedia became synthetic art, just as the Bauhaus looked for "architecture." Currently, this kind of expression transitions from art to entertainment, and permeates daily life.3. The method with interactive art work. Not only artworks of installation, but also TV games and web design have interactive construction as an indispensable interface. The aesthetic value of these visual works will be appreciated when the user starts the action by hitting a touchpad, pushing buttons, or clicking a mouse. To make this kind of artwork, one needs to consider the latent relationships between humans and work, and establish the input-output order for the method of construction.4. The problem of virtual reality. The term "virtual reality" is used by some art teachers as criticism against digital works such as computer graphics. These teachers insist that there is no reality there. One can, however, get an aesthetic feeling through sensory information, imagination, and sensitivity, even though what one sees is an illusion. The feeling of reality a picture of an apple gives, for example, may be equal to a computer graphic apple.Human imagination also creates "virtual reality" beyond reality in the myth, the novel, and so on. It can be said that this is the basis for human creativity.Furthermore, expression by image media raises the problem of a "reality" in which material experience is important to encounterthe world directly. Such an argument discusses multimedia as a tool of expression and a teaching material while reconsidering human reality.More recently, "media literacy" (ability to read and understand media) became an important point of discussion for Japanese educators. Usually, in this discussion, the critical ability to talk back to the television program is emphasized. However, through art... (shrink)
