Skilled activity, such as shaving or dancing, differs in important ways from many of the stock examples that are employed by action theorists. Some critics of the causal theory of action contend that such a view founders on the problem of skilled activity. This paper examines how a causal theory can be extended to the case of skilled activity and defends the account from its critics.

Cognitive Science is a single-source undergraduate text that broadly surveys the theories and empirical results of cognitive science within a consistent computational perspective. In addition to covering the individual contributions of psychology, philosophy, linguistics, and artificial intelligence to cognitive science, the book has been revised to introduce the connectionist approach as well as the classical symbolic approach and adds a new chapter on cognitively related advances in neuroscience. Cognitive science is a rapidly evolving field that is characterized by considerable contention (...) among different views and approaches. Cognitive Science presents these in a relatively neutral manner. It covers many new orientations theories and findings, embedding them in an integrated computational perspective and establishing a sense of continuity and contrast with more traditional work in cognitive science. The text assumes no prerequisite knowledge, introducing all topics in a uniform, accessible style. Many topics, such as natural language processing and vision, however, are developed in considerable depth, which allows the book to be used with more advanced undergraduates or even in beginning graduate settings.

Ryle’s account of practical knowing is much controverted. The paper seeks to place present disputations in a larger context and draw attention to the connection between Ryle’s preoccupations and Aristotle’s account of practical reason, practical intelligence, and the way in which human beings enter into the way of being and acting that Aristotle denominates ethos . Considering matters in this framework, the author finds inconclusive the arguments that Stanley and Williamson offer for seeing knowing how to as a special case (...) of knowing that. The paper then explores certain implications of the author’s position for the philosophy of mind and the grammatical analysis of constructions involving ‘know how to’. It ends with a neo-Rylean remark about Aristotelian nous. (shrink)

According to the dominant computational approach in cognitive science, cognitive agents are digital computers; according to the alternative approach, they are dynamical systems. This target article attempts to articulate and support the dynamical hypothesis. The dynamical hypothesis has two major components: the nature hypothesis (cognitive agents are dynamical systems) and the knowledge hypothesis (cognitive agents can be understood dynamically). A wide range of objections to this hypothesis can be rebutted. The conclusion is that cognitive systems may well be dynamical systems, (...) and only sustained empirical research in cognitive science will determine the extent to which that is true. (shrink)

‘There is no place in the phenomenology of fully absorbed coping’, writes Hubert Dreyfus, ‘for mindfulness. In flow, as Sartre sees, there are only attractive and repulsive forces drawing appropriate activity out of an active body’1. Among the many ways in which history animates dynamical systems at a range of distinctive timescales, the phenomena of embodied human habit, skilful movement, and absorbed coping are among the most pervasive and mundane, and the most philosophically puzzling. In this essay we examine both (...) habitual and skilled movement, sketching the outlines of a multidimensional framework within which the many differences across distinctive cases and domains might be fruitfully understood. Both the range of movement phenomena which can plausibly be seen as instances of habit or skill, and the space of possible theories of such phenomena are richer and more disparate than philosophy easily encompasses. We seek to bring phenomenology into contact with relevant movements in psychological theories of skilful action, in the belief that phenomenological philosophy and cognitive science can be allies rather than antagonists.

People are unable to report how they decide whether to move backwards or forwards to catch a ball. When asked to imagine how their angle of elevation of gaze would change when they caught a ball, most people are unable to describe what happens although their interception strategy is based on controlling changes in this angle. Just after catching a ball, many people are unable to recognise a description of how their angle of gaze changed during the catch. Some people (...) confidently choose incorrect descriptions that would guarantee failure of interception demonstrating unconscious knowledge co-existing with systematically different conscious beliefs. Where simple solutions to important evolutionary problems exist, unconscious perception needs to be impervious to conscious beliefs. (shrink)

It is widely thought that focusing on highly skilled movements while performing them hinders their execution. Once you have developed the ability to tee off in golf, play an arpeggio on the piano, or perform a pirouette in ballet, attention to what your body is doing is thought to lead to inaccuracies, blunders, and sometimes even utter paralysis. Here I re-examine this view and argue that it lacks support when taken as a general thesis. Although bodily awareness may often interfere (...) with well-developed rote skills, like climbing stairs, I suggest that it is typically not detrimental to the skills of expert athletes, performing artists, and other individuals who endeavor to achieve excellence. Along the way, I present a critical analysis of some philosophical theories and behavioral studies on the relationship between attention and bodily movement, an explanation of why attention may be beneficial at the highest level of performance and an error theory that explains why many have thought the contrary. Though tentative, I present my view as a challenge to the widespread starting assumption in research on highly skilled movement that at the pinnacle of skill attention to one's movement is detrimental.

Hubert Dreyfus has defended a novel view of agency, most notably in his debate with John McDowell. Dreyfus argues that expert actions are primarily unreflective and do not involve conceptual activity. In unreflective action, embodied know-how plays the role reflection and conceptuality play in the actions of novices. Dreyfus employs two arguments to support his conclusion: the argument from speed and the phenomenological argument. I argue that Dreyfus's argumentative strategies are not successful, since he relies on a dubious assumption about (...) concepts and reflection. I suggest that Dreyfus is committed to a minimal view of conceptuality in action. (shrink)

You know that George W. Bush is the U.S. president, but you know how to ride a bicycle. What's the difference? According to intellectualists, not much: either knowing how to do something is a matter of knowing that something is the case or, at the very least, know-how requires a prior bit of theoretical knowledge. Anti-intellectualists deny this order of priority: either knowing-how and knowing-that are independent or, at the very least, knowing that something is the case requires a prior (...) bit of know-how. Much of the dispute centers on the relationship between knowing how to do something and having an ability to do it. If having an ability is necessary and sufficient for knowing-how, this is thought to provide comfort for anti-intellectualists. This paper traces the place of ability in the know-how/know-that debate from Ryle's seminal statement of anti-intellectualism through Stanley and Williamson's more recent defense of intellectualism.

McDowell's claim that "in mature human beings, embodied coping is permeated with mindedness",1 suggests a new version of the mentalist myth which, like the others, is untrue to the phenomenon. The phenomena show that embodied skills, when we are fully absorbed in enacting them, have a kind of non-mental content that is non-conceptual, non-propositional, non-rational and non-linguistic. This is not to deny that we can monitor our activity while performing it. For solving problems, learning a new skill, receiving coaching, and (...) so forth, such monitoring is invaluable. But monitoring what we are doing as we are doing it degrades performance to at best competence. On McDowell's view, there is no way to account for such a degradation in performance since the same sort of content would be involved whether we were fully absorbed in or paying attention to what we were doing. McDowell claims that it is an advantage of his conceptualism that it avoids any foundationalist attempt to build up the objective world on the basis of an indubitable Given or any other ground-floor experience. And, indeed, if the world is all that is the case and our minds are unproblematically open to it, all experience is on the same footing. But one must distinguish motor intentionality, and the interrelated solicitations our coping body is intertwined with, from conceptual intentionality and the world of propositional structures it opens onto. The existential phenomenologist can then agree with McDowell in rejecting traditional foundationalisms, while yet affirming and describing the ground-floor role of motor intentionality in providing the support on which all forms of conceptual intentionality are based.

In previous work I urged that the perceptual experience we rational animals enjoy is informed by capacities that belong to our rationality, and - in passing - that something similar holds for our intentional action. In his Presidential Address, Hubert Dreyfus argued that I thereby embraced a myth, "the Myth of the Mental". According to Dreyfus, I cannot accommodate the phenomenology of unreflective bodily coping, and its importance as a background for the conceptual capacities exercised in reflective intellectual activity. My (...) paper responds to this accusation. Dreyfus misreads my invocation of Aristotle, and is thereby led to suppose, wrongly, that I conceive rationality as detached, brought to bear on practical predicaments from a standpoint other than one of immersion in them. I urge that even unreflective bodily coping, on the part of rational animals, is informed by their rationality. Dreyfus mentions Heidegger’s distinction, which is picked up by Gadamer, between being oriented towards the world and merely inhabiting an environment. But he sets it aside, whereas it is crucial for the issue between us. Engaged bodily coping involves responsiveness to affordances, and responsiveness to affordances on the part of rational animals belongs to their relation to the world. I explain how the idea that conceptual capacities are actualized in our perceptual experience is connected with the thought that our perceptual experience opens us to the world. Finally, I suggest that the real myth in this area is the conception of rationality underlying Dreyfus’s resistance to my picture. (shrink)

Existential phenomenologists hold that the two most basic forms of intelligent behavior, learning, and skillful action, can be described and explained without recourse to mind or brain representations. This claim is expressed in two central notions in Merleau-Ponty's Phenomenology of Perception: the intentional arc and the tendency to achieve a maximal grip. The intentional arc names the tight connection between body and world, such that, as the active body acquires skills, those skills are “stored”, not as representations in the mind, (...) but as dispositions to respond to the solicitations of situations in the world. A phenomenology of skill acquisition confirms that, as one acquires expertise, the acquired know-how is experienced as finer and finer discriminations of situations paired with the appropriate response to each. Maximal grip names the body's tendency to refine its responses so as to bring the current situation closer to an optimal gestalt. Thus, successful learning and action do not require propositional mental representations. They do not require semantically interpretable brain representations either.Simulated neural networks exhibit crucial structural features of the intentional arc, and Walter Freeman's account of the brain dynamics underlying perception and action is structurally isomorphic with Merleau-Ponty's account of the way a skilled agent is led by the situation to move towards obtaining a maximal grip.

There is a widespread view that well-learned skills are automated, and that attention to the performance of these skills is damaging because it disrupts the automatic processes involved in their execution. This idea serves as the basis for an account of choking in high pressure situations. On this view, choking is the result of self-focused attention induced by anxiety. Recent research in sports psychology has produced a significant body of experimental evidence widely interpreted as supporting this account of choking in (...) certain kinds of complex sensorimotor skills. We argue against this interpretation, pointing to problems with both the empirical evidence and the underlying theory. The experimental research fails to provide direct support for the central claims of the self-focus approach, contains inconsistencies, and suffers from problems of ecological validity. In addition, qualitative studies of choking have yielded contrary results. We further argue that in their current forms the self-focus and rival distraction approaches both lack the theoretical resources to provide a good theory of choking, and we argue for an expanded approach. Some of the elements that should be in an expanded approach include accounts of the features of pressure situations that influence the psychological response, the processes of situation appraisal, and the ways that attentional control can be overwhelmed, leading to distraction in some cases, and in others, perhaps, to damaging attention to skill execution. We also suggest that choking may sometimes involve performance-impairing mechanisms other than distraction or self-focus. (shrink)

Arguments in favor of anti-representationalism in cognitive science often suffer from a lack of attention to detail. The purpose of this paper is to fill in the gaps in these arguments, and in so doing show that at least one form of anti- representationalism is potentially viable. After giving a teleological definition of representation and applying it to a few models that have inspired anti- representationalist claims, I argue that anti-representationalism must be divided into two distinct theses, one ontological, one (...) epistemological. Given the assumptions that define the debate, I give reason to think that the ontological thesis is false. I then argue that the epistemological thesis might, in the end, turn out to be true, despite a potentially serious difficulty. Along the way, there will be a brief detour to discuss a controversy from early twentieth century physics. (shrink)

Beyond the Learning Curve reviews and considers the psychology of skill acquisition. In so doing the authors propose a whole new theory of mental function - demonstrating that the mind is subject to the same natural laws as the physical world. Accessibly written, 'Beyond the learning curve' is a thought provoking and challenging new text for students and researchers in the cognitive sciences.

The first comprehensive presentation of the dynamical approach to cognition. It contains a representative sampling of original, current research on topics such as perception, motor control, speech and language, decision making, and development.

This is a new release of the original 1949 edition.

The first full-scale history of cognitive science, this work addresses a central issue: What is the nature of knowledge?

Many philosophers believe that there is a fundamental distinction between knowing that something is the case and knowing how to do something. According to Gilbert Ryle, to whom the insight is credited, knowledge-how is an ability, which is in turn a complex of dispositions. Knowledge-that, on the other hand, is not an ability, or anything similar. Rather, knowledge-that is a relation between a thinker and a true proposition.

Back in 1950, while a physics major at Harvard, I wandered into C.I. Lewis’s epistemology course. There, Lewis was confidently expounding the need for an indubitable Given to ground knowledge, and he was explaining where that ground was to be found. I was so impressed that I immediately switched majors from ungrounded physics to grounded philosophy.
