I.One of the main undertakings of the embodied approach to cognition is to spell out effectively the intuition that our body shapes what our mind can do . This endeavor is motivated—among other things – by the deep sense of awe that cognitive scientists experience in front of the sophistication, flexibility, and variability that can be reached by the motor abilities of well-trained humans. In particular, excellence in sporting skills inspires embodied cognition by exhibiting tangible evidence that the details of (...) our bodily constitution are not accidental to our mental powers, but define them in various inherent ways: not only because the informational processes that realize our intelligent functions are specifically regulated, distributed, filtered, or scaffolded by the physical and biological compound that implements them ; but also because the modes and the efficacy of our practical intelligence primarily depend on the o ..

Whilst in recent years sports studies have addressed the calls ‘to bring the body back in’ to theorisations of sport and physical activity, the ‘promise of phenomenology’ remains largely under-realised with regard to sporting embodiment. Relatively few accounts are grounded in the ‘flesh’ of the lived sporting body, and phenomenology offers a powerful framework for such analysis. A wide-ranging, multi-stranded, and interpretatively contested perspective, phenomenology in general has been taken up and utilised in very different ways within different disciplinary fields. (...) The purpose of this article is to consider some selected phenomenological threads, key qualities of the phenomenological method, and the potential for existentialist phenomenology in particular to contribute fresh perspectives to the sociological study of embodiment in sport and exercise. It offers one way to convey the ‘essences’, corporeal immediacy and textured sensuosity of the lived sporting body. The use of Interpretative Phenomenological Analysis (IPA) is also critically addressed. Key words: phenomenology; existentialist phenomenology; interpretative phenomenological analysis (IPA); sporting embodiment; the lived-body; Merleau-Ponty. (shrink)

Over recent years, there has been a resurgence of interest in arguments favouring intellectualism—the view that Ryle’s epistemic distinction is invalid because knowing how is in fact nothing but a species of knowing that. The aim of this paper is to challenge intellectualism by introducing empirical evidence supporting a form of knowing how that resists such a reduction. In presenting a form of visuomotor pathology known as visual agnosia, I argue that certain actions performed by patient DF can be distinguished (...) from a mere physical ability because they are (1) intentional and (2) knowledge-based; yet these actions fail to satisfy the criteria for propositional knowledge. It is therefore my contention that there exists a form of intentional action that not only constitutes a genuine claim to knowledge but, in being irreducible to knowing that, resists the intellectualist argument for exhaustive epistemic reduction.

There is disagreement in the literature about the exact nature of the phenomenon of empathy. There are emotional, cognitive, and conditioning views, applying in varying degrees across species. An adequate description of the ultimate and proximate mechanism can integrate these views. Proximately, the perception of an object's state activates the subject's corresponding representations, which in turn activate somatic and autonomic responses. This mechanism supports basic behaviors that are crucial for the reproductive success of animals living in groups. The Perception-Action Model, (...) together with an understanding of how representations change with experience, can explain the major empirical effects in the literature. It can also predict a variety of empathy disorders. The interaction between the PAM and prefrontal functioning can also explain different levels of empathy across species and age groups. This view can advance our evolutionary understanding of empathy beyond inclusive fitness and reciprocal altruism and can explain different levels of empathy across individuals, species, stages of development, and situations. Key Words: altruism; cognitive empathy ; comparative; emotion; emotional contagion; empathy ; evolution; human; perception-action; perspective taking. (shrink)

In this paper I return to Hubert Dreyfus’ old but influential critique of artificial intelligence, redirecting it towards contemporary predictive processing models of the mind (PP). I focus on Dreyfus’ arguments about the “frame problem” for artificial cognitive systems, and his contrasting account of embodied human skills and expertise. The frame problem presents as a prima facie problem for practical work in AI and robotics, but also for computational views of the mind in general, including for PP. Indeed, some of (...) the issues it presents seem more acute for PP, insofar as it seeks to unify all cognition and intelligence, and aims to do so without admitting any cognitive processes or mechanisms outside of the scope of the theory. I contend, however, that there is an unresolved problem for PP concerning whether it can both explain all cognition and intelligent behavior as minimizing prediction error with just the core formal elements of the PP toolbox, and also adequately comprehend (or explain away) some of the apparent cognitive differences between biological and prediction-based artificial intelligence, notably in regard to establishing relevance and flexible context-switching, precisely the features of interest to Dreyfus’ work on embodied indexicality, habits/skills, and abductive inference. I address several influential philosophical versions of PP, including the work of Jakob Hohwy and Andy Clark, as well as more enactive-oriented interpretations of active inference coming from a broadly Fristonian perspective.

Worrying is the central feature of generalized anxiety disorder . Many people worry from time to time, but in GAD the worrying is prolonged and difficult to control. Worrying is a specific way of coping with perceived threats and feared situations. Meanwhile, it is not considered to be a helpful coping strategy, and the phenomenological account developed in this paper aims to show why. It builds on several phenomenological notions and in particular on Michael Wheeler's application of these notions to (...) artificial intelligence and the cognitive sciences. Wheeler emphasizes the value of 'online intelligence' as contrasted to 'offline intelligence'. I discuss and apply these concepts with respect to worrying as it occurs in GAD, suggesting that GAD patients overrate the value of detached contemplation , while underrating their embodied-embedded adaptive skills . I argue that this phenomenological account does not only help explaining why worrying is used as a coping strategy, but also why cognitive behavioral therapy is successful in treating GAD. (shrink)

This paper discusses different approaches incognitive science and artificial intelligenceresearch from the perspective of radicalconstructivism, addressing especially theirrelation to the biologically based theories ofvon Uexküll, Piaget as well as Maturana andVarela. In particular recent work in New AI and adaptive robotics on situated and embodiedintelligence is examined, and we discuss indetail the role of constructive processes asthe basis of situatedness in both robots andliving organisms.

Intellectualists suggest that practical knowledge, or ‘knowing- how’, can be reduced to propositional knowledge, or ‘knowing-that’. Anti-intellectualists, on the contrary, suggest, following the original insights by Ryle, that such a reduction is not possible. Rejection of intellectualism can be proposed either by offering purely philosophical analytical arguments, or by recruiting empirical evidence from cognitive science about the nature of the mental representations involved in these two forms of knowledge. In this paper, I couple these two strategies in order to analyze (...) some crucial reasons for which intellectualism seems not to be the best theory we have to correctly understand and describe practical knowledge. In particular, I will start from a specific philosophical account against intellectualism offered by Dickie :737–745, 2012), and suggest that it can be supported by current experimental results coming from motor neuroscience. The claim of the paper is that there is at least one kind of practical knowledge, which I call motor knowledge, and which is at the basis of the performance of skilled action, which cannot be reduced to propositional knowledge.

In this paper, I will argue that J. Patočka’s conception of three movements of human existence can be considered a contribution to the “pragmatic turn” in phenomenology. In order to demonstrate this contribution, I will first recapitulate the context of pragmatic turn, outlining both Heidegger’s original position and its consequent pragmatic interpretation offered by H. Dreyfus and other scholars. The core of the pragmatic interpretation is based on a modification of the Primacy of Praxis thesis that can be described as (...) the Primacy of Practic_es_ thesis, according to which our background practices, i.e., the ‘contingent ways of acting and judging,’ operate as a “source” of intelligibility. Based on Patočka’s criticisms, I will further argue that Heidegger-inspired pragmatism is hampered by the opposition between authentic and inauthentic disclosure, leading to both the rigidification of everyday practices and rendering authentic disclosure formal and empty. In the final section, I will demonstrate that Patočka’s own conception of the three movements of existence can be seen as committed to the Primacy of Practices thesis and that this version of the Primacy of Practice thesis is more acceptable because it does not share the disdainful attitude in regards of the public world.

This paper discusses the nature and limits of player embodiment within digital games. We identify a convergence between everyday bodily actions and activity within digital environments, and a trend towards incorporating natural forms of movement into gaming worlds through mimetic control devices. We examine recent literature in the area of immersion and presence in digital gaming; Calleja’s (2011) recent Player Involvement Model of gaming is discussed and found to rely on a probematic notion of embodiment as 'incorporation'. We go on (...) to further reflect on the nature of player involvement in digital gaming environments by applying insights from Maurice Merleau-Ponty's Phenomenology of Perception. It is argued that digital embodiment differs so significantly from primordial embodiment that any idea of total immersion is simply fantasy. We subsequently argue that digital game media nonetheless provide us with unique opportunities for exploring the nature of distinctively human forms of embodiment, and so we need more complete and more reliable phenomenological descriptions of the experiences associated with computer games.

The aim of this paper is to provide a theoretical and formal framework to understand how the proprioceptive and kinesthetic system learns about body position and possibilities for movement in ongoing action and interaction. Whereas most weak embodiment accounts of proprioception focus on positionalist descriptions or on its role as a source of parameters for internal motor control, we argue that these aspects are insufficient to understand how proprioception is integrated into an active organized system in continuous and dynamic interaction (...) with the environment. Our strong embodiment thesis is that one of the main theoretical principles to understand proprioception, as a perceptual experience within concrete situations, is the coupling with kinesthesia and its relational constitution—self, ecological, and social. In our view, these aspects are underdeveloped in current accounts, and an enactive sensorimotor theory enriched with phenomenological descriptions may provide an alternative path toward explaining this skilled experience. Following O'Regan and Noë sensorimotor contingencies conceptualization, we introduce three distinct notions of proprioceptive kinesthetic-sensorimotor contingencies, which we describe conceptually and formally considering three varieties of perceptual experience in action: PK-SMCs-self, PK-SMCs-self-environment, and PK-SMC-self-other. As a proof of concept of our proposal, we developed a minimal PK model to discuss these elements in detail and show their explanatory value as important guides to understand the proprioceptive/kinesthetic system. Finally, we also highlight that there is an opportunity to develop enactive sensorimotor theory in new directions, creating a bridge between the varieties of experiences of oneself and learning skills.

A crucial task for sport research is to understand and explain the processes and conditions underlying skillful motor behavior. One way to account for these processes and conditions is to describe and analyze the distinct stages a learner goes through when acquiring a skill. This article starts by elaborating one of the most dominant conceptualizations of motor skills in sport, namely the information-processing approach to skills, and then it briefly recapitulates Hubert and Stuart Dreyfus’s phenomenology of skill acquisition. In a (...) second part, these two distinct perspectives of skills are discussed. The discussion progresses in a dialectical way where the author alternately argues for both perspectives. Emerging from this dialectic, the article presents two arguments for why Dreyfus’s phenomenology of skill acquisition is superior to the information-processing approach. (shrink)

RESUMEN Nos adentramos en esos procesos de subjetivación en los que el músico de jazz experimenta en sí otras formas de corporalidad, que se dirimen entre sujeción a esquemas y ruptura de los corsés por una teatralidad en escena. Aparentemente, en la improvisación prima lo subversivo y la reificación del músico como autor libre; sin embargo, observamos empíricamente una corporalidad plural que trasciende el espacio de la escena y que facilita que todos los actores intervengan en el proceso de creación. (...) Hallamos una red de solidaridad que desplaza continuamente los puntos fijos por donde transita la música; así, cuando a un músico le falta el aire, su compañero le da el relevo. Si lo fundamental en la praxis de la música son las continuas alternativas que ofrece, concluimos con una reflexión ética sobre la naturaleza transitoria de la música y su temporalidad kairológica, en la que el músico, sintiendo la brevedad del instante de la nota que muere cuando nace, se reencuentra con lo insignificante de la que está hecha su condición humana. ABSTRACT We enter these processes of subjectivation in which the jazz musician experiences in himself other forms of corporeality, which are settled between subjection to schemes and breakup of the corsets by a theatricality on stage. Apparently, in improvisation what is subversive and the reification of the musician as a free author take priority; nevertheless, we empirically observe a plural corporeality that goes beyond the space of the scene and that facilitates that all the actors take part in the process of creation. We found a solidarity network that continuously displaces the fixed points where music circulates; thus, when a musician is short of breath, his partner takes over. If what is fundamental in the praxis of music is the continuous alternatives it offers, we conclude with an ethical reflection on the transitory nature of music and its kairological temporality, in which the musician, feeling the briefness of the instant of the note that dies when it is born, joins the insignificance of his human condition.

This paper pursues the intertwined tracks of robotics and art since the mid 20th century, taking a loose chronological approach that considers both the devices themselves and their discursive contexts. Relevant research has occurred in a variety of cultural locations, often outside of or prior to formalized robotics contexts. Research was even conducted under the aegis of art or cultural practices where robotics has been pursued for other than instrumental purposes. In hindsight, some of that work seems remarkably prescient of (...) contemporary trends. The context of cultural robotics is a highly charged interdisciplinary test environment in which the theory and pragmatics of technical research confronts the phenomenological realities of physical and social being in the world, and the performative and processual practices of the arts. In this context, issues of embodiment, material instantiation, structural coupling, and machine sensing have provoked the reconsideration of notions of (machine) intelligence and cognitivist paradigms. The paradoxical condition of robotics vis-à-vis artificial intelligence is reflected upon. This paper discusses the possibility of a new embodied ontology of robotics that draws upon both cybernetics and post-cognitive approaches. (shrink)

This paper presents a discussion of an everyday ontology of witnessing drawing on the writings of Martin Heidegger, cognitive science and presence research. We begin by defining witnessing: to witness we must be present ; and that which is witnessed must be available. Witnessing is distinguished from perceiving in that it implies and requires a record (a representation) of what has been perceived. Presence and availability are (relatively) uncontroversial but finding a place for representation, which is a classically dualistic concept, (...) in an ontological account potentially presents difficulties. We address this problem by recognising that being available, ready-to-hand and proximal can also serve to represent the very thing being witnessed. (shrink)

Heidegger's primary concern in Being and Time is the question of the meaning of being—a distinctly ontological concern. Yet, with discussions of death, guilt, conscience, anxiety, uncanniness, authenticity, and inauthenticity, Heidegger seems to end up in existential territory. The ontological import of these existential excursions is difficult to discern—indeed, it has not been identified in leading interpretations. In this paper, I aim to highlight the ontological import of Heidegger's analysis of anxiety—it manifests the inadequacy of Dasein's fallen and inauthentic self-understanding, (...) which is motivated by the inadequacy of Dasein's fallen and inauthentic, average understanding of being. In making this case, I will clarify the sense in which anxiety involves an experience of world-collapse and show how it functions to reveal the possibilities of authenticity and inauthenticity.

This article develops a critical theory of human–computer interaction intended to test some of the assumptions and omissions made in the field as it transitions from a cognitive theoretical frame to a phenomenological understanding of user experience described by Harrison et al. as a third research paradigm and similarly Bødker :24–31; Bødker, Interactions 22):24–31, 2015) as third-wave HCI. Although this particular focus on experience has provided some novel avenues of academic enquiry, this article draws attention to a distinct bridge between (...) the conventional HCI disciplinary concerns with predominantly task-based digital work and use context and a growing business interest in consumer experiences in digital environments. Critical HCI addresses the problem of experience in two interrelated ways. On one hand, it explores the role market logic plays in putting user experiences to work. On the other hand, it engages with ontological understandings of experience hitherto realized in HCI by way of a phenomenological matrix. The article concludes by bringing in an old thinker to consider experience in novel ways that relate ontological concerns to a broader political concept of experience capitalism. (shrink)

In this thesis I apply Merleau-Ponty's brand of existential phenomenology to the developmental language disorder 'dyslexia'. Developmental dyslexia is marked by an unexpected failure to acquire written language skills, in particularly reading, spelling and aspects of writing, and has primarily been studied by experimental cognitive psychology, physiology, and more recently, the neurosciences. The current explanatory paradigm holds the view that symptoms of dyslexia are caused by deficits in phonological skills, in particularly verbal memory and phoneme awareness. As a means of (...) facilitating previous research, I take a phenomenological approach to the pre-reflective, lived experience of dyslexia by studying the peculiar style of intentional relationships that are developed by dyslexics in linguistic situations. This approach adopts a non-causal, descriptive methodology which attends to the manner in which dyslexics not only have a disrupted experience of the written word, but also a meaningful relationship with language. Using the notion of the 'lived body', I propose that dyslexics are marked by a loosening of body intentionality in linguistic situations, and this is further interpreted as an incohesive sedimentation of skills. I apply these general findings to the topics of spatiality, expression and temporality, and conclude that dyslexics exhibit a different style of being-in-the-world. This difference in style is characterised as an interaction between the propensity to foreclose the transitional and differential structures of perceptual experience, and moreover, the possibility of sustaining a provisional relationship with language through the development of compensatory strategies, the latter of these observations prompting a new line of future qualitative research.

In this paper I discuss Hegel's views on the determination of intentions. The main point is that it pays to distinguish sufficiently clearly four perspectives to human action: 1) The agent's "moral" perspective and the understanding and description under which the agent acted; from this perspective we can thematize the operative intention-in-action and distinguish "action" from "deed". 2) The agent's retrospective awareness and appropriation of the action: was what I did really justified and did it express my true goals? 3) (...) The retrospective takes of others concerning the action, from within relevant social practices and the prevailing Sittlichkeit. 4) The perspective of Reason or Idea as emerging in the world history. In this paper I use this differentiation of perspectives to discuss Hegel's views on action. I defend the primacy of the individual herself in the first aspect mentioned, in what Hegel calls the "moral" perspective. Robert Pippin's idea of "retrospective" determination of intentions is analyzed and (on some readings) criticized. (shrink)

In this paper, I argue that Merleau-Ponty reformulates traditional transcendental philosophy in the sense of showing that the a priori conditions of experience cannot be separated from the concrete experiences. In the first section, I revisit Kant and Husserl, to show how these authors delimit the transcendental conditions as a formal domain independent from any concrete experience. Then I reconstruct the argumentative move through which Merleau-Ponty rejects this formal delimitation of the transcendental sphere and reintroduces it as inseparable from empirical (...) domain, initially in The Structure of Behavior and later in Phenomenology of Perception.

Most cognitive scientists are committed to some version of representationalism, the view that intelligent behavior is caused by internal processes that involve computations over representations. Phenomenologists, however, argue that certain types of intelligent behavior, engaged coping skills, are nonrepresentational. Recent neuroscientific work on multiple memory systems indicates that while many types of intelligent behavior are representational, the types of intelligent behavior cited by phenomenologists are indeed nonrepresentational. This neuroscientific research thus vindicates a key phenomenological claim about the nature of intelligent (...) behaviour. It also provides a framework for the ongoing reconciliation of cognitive science and phenomenology. (shrink)

PurposeThe purpose of this paper is to reflect on society's relationship with technology and particularly our increasing dependence on electronic technology – so‐called eDependency. The paper argues that technology is not neutral and we must engage with the moral issues that arise from our relationship with it.Design/methodology/approachSociety's relationship with technology is examined through the lens of Socrates' consideration of the technology of writing. It identifies “technophilia” as a major theme in society and “neo‐Luddism” as the Socrates‐like examination of the benefits (...) of technology.FindingsWhile rejecting both technology determinism and technology presentism the paper argues technology is not neutral and does afford social change within a particular social ecology. The authors suggest that ultimately the use of all technology, including the technology underpinning eDependency, leads to important moral questions which deserve considered debate. The paper concludes by arguing that the Information Systems (IS) discipline should take the mantle of King Thamus and that the study of these issues should become a key concern for the discipline.Originality/valueIn an age of technophilia, this paper calls considered debate on the moral issues that arise from our relationship with technology, how it is appropriated, to whose benefit, and how we change it and will be changed by it.

Engagement is important to the success of applications, systems and artefacts as diverse as robotics, pedagogy, games, interactive installations, and virtual reality applications. Yet engagement has proved to be remarkably difficult to define as it can take many forms, so many that it is difficult to isolate what these different instantiations have in common. Instead of pursuing an empirical perspective, the human side of engagement, namely, involvement is considered from a broadly Heideggerian perspective. As Heidegger has a deserved reputation for (...) philosophical obscurity, all of the concepts adopted from his work are mapped onto the more familiar languages and vocabularies of psychology, human–computer interaction and cognitive science. It is argued that technology is engaging and our response to it is to be involved (with it). This resulting involvement–engagement dyad is thus an explicitly holistic account recognising roles for affordance, purpose, identity, affect and embodiment. (shrink)

I propose a semi-eliminative reduction of Fodors concept of module to the concept of attractor basin which is used in Cognitive Dynamic Systems Theory (DST). I show how attractor basins perform the same explanatory function as modules in several DST based research program. Attractor basins in some organic dynamic systems have even been able to perform cognitive functions which are equivalent to the If/Then/Else loop in the computer language LISP. I suggest directions for future research programs which could find similar (...) equivalencies between organic dynamic systems and other cognitive functions. This type of research could help us discover how (and/or if) it is possible to use Dynamic Systems Theory to more accurately model the cognitive functions that are now being modeled by subroutines in Symbolic AI computer models. If such a reduction of subroutines to basins of attraction is possible, it could free AI from the limitations that prompted Fodor to say that it was impossible to model certain higher level cognitive functions.

The practices of the arts—plastic and performing—deal in direct sensorial engagement with the body, with materiality, with artifacts and tools, with spaces, and with other people. The arts are centrally concerned with intelligent doing. Conventional explanations of the cognitive dimensions of arts practices have been unsatisfying because internalist paradigms provides few useful tools to discuss embodied dimensions of cognition.

There seem to be good reasons to think that there must be body representations or some kind of body content required for riding a bike or grabbing a cup of coffee. However, when I ride a bike or grab a cup of coffee, am I just representing the bike and the cup? Or am I actually also representing my body and bodily movements? The thesis of this paper is that the body not only figures in the content that guides everyday (...) activities but that it must. How is this possible? Exactly what elements of the subject’s body can be said to figure in this content? I will proceed in three steps: in the first, I bring together the conceptual resources that seem to be required; in the second, I discuss a couple of proposals about how to link the notion of affordance and the topic of bodily representations, arguing that they are misguided; finally, I propose a view according to which the body’s physical and spatial properties are an unavoidable part of the content that guides everyday activities.

This article deals with science content “in the making” and in particular the role of the body in producing scientific phenomena. While accounts of scientists’ work have repeatedly demonstrated, how producing phenomena requires immense amounts of time and effort, involving tinkering and manual labor, this is a little empirically studied content in science education. Seeking to shed light on how the body is involved with materiality to produce physics phenomena, and in what terms this is learning physics content, the article (...) first examines how bodily tinkering is a necessary part of knowing physics through reviewing major accounts of science studies and research in science education. Secondly, drawing on phenomenology and pragmatist ideas, the article examines how students’ bodies need to be educated in the transactional process with material and artifacts to produce phenomena in the context of science learning in lower secondary physics education. Demonstrating that embodied phenomena production is an inescapable part of learning scientific inquiry, and that bodies are just as much a part of the subject physics as conceptual knowledge, we suggest that the education of students’ bodies needs to be made an explicit content. This is important not only for making tacit content accessible to all, but also for addressing epistemological understandings of what science and technology is about. (shrink)

This work is a response to a request from the phenomenology group at Edith Cowan University. The paper is based on seminar discussions, experiences and ideas that have been contextualized within phenomenological literature. The notion of phenomenology as intervention has become increasingly apparent owing to the value of its practical applications in the human and social sciences. The paper explores the theme with special reference to research and psychotherapeutic interventions. Indo-Pacific Journal of Phenomenology , Volume 1, Edition 2 September 2001.
