The discovery of mirror neurons has been hailed as one of the most exciting developments in neuroscience in the past few decades. These neurons discharge in response to the observation of others’ actions. But how are we to understand the function of these neurons? In this paper I defend the idea that mirror neurons are best conceived as components of a sensory system that has the function to perceive action. In short, mirror neurons are part of a hitherto unrecognized “sixth sense”. In this spirit, research should move toward developing a psychophysics of mirror neurons.

When conceived as an empirical claim, it is natural to wonder how one might test the hypothesis of multiple realization. I consider general issues of testability, show how they apply specifically to the hypothesis of multiple realization, and propose an auxiliary assumption that, I argue, must be conjoined to the hypothesis of multiple realization to ensure its testability. I argue further that Bechtel and Mundale go astray because they fail to appreciate the need for this auxiliary assumption. †To contact the author, please write to: Department of Philosophy, University of Wisconsin–Madison, 5185 Helen C.

While there is controversy over which of several naturalistic theories of the mental is most plausible, there is consensus regarding the desideratum of a naturalistically respectable theory. A naturalistic theory of the mental, it is agreed, must explicate representation in nonintentional terms. I argue that this constraint does not get at the heart of what it is to be natural. On the one hand, it fails to provide us with a meaningful distinction between the natural and the unnatural. On the other hand, it unfairly suggests that we withhold judgment on those successes our sciences of the mind have already achieved until a convincing decomposition of the mental is available. I urge a new conception of naturalism that focuses less upon ontological considerations and more upon methodological ones

Jaegwon Kim’s causal exclusion argument has rarely been evaluated from an empirical perspective. This is puzzling because its conclusion seems to be making a testable claim about the world: supervenient properties are causally inefficacious. An empirical perspective, however, reveals Kim’s argument to rest on a mistaken conception about how to test whether a property is causally efficacious. Moreover, the empirical perspective makes visible a metaphysical bias that Kim brings to his argument that involves a principle of non‐inclusion.

Successful athletic performance requires precision in many respects. A batter stands behind home plate awaiting the arrival of a ball that is less than three inches in diameter and moving close to 100 mph. His goal is to hit it with a ba­­t that is also less than three inches in diameter. This impressive feat requires extraordinary temporal and spatial coordination. The sweet spot of the bat must be at the same place, at the same time, as the ball. A basketball player must keep a ball bouncing as she speeds from one end of the court to another, evading defensive players. She may never break pace as she lifts from the ground, throwing the ball fifteen feet toward a hoop that is eighteen inches in diameter. One task facing a psychologist involves explaining how the body does such things within the sometimes very demanding spatial and temporal constraints that a given task imposes. Part of the goal of this chapter is to sketch the commitments of an embodied approach to such an explanation. We shall see that an embodied account of motor skills draws concepts that depart radically from more traditional cognitivist theories of motor activity. Similarly, because an embodied approach to cognition introduces new ways to understand the human capacity for social interaction, it also promises to shed new light on how athletes coordinate their actions with each other.

Since the founding of psychophysics in the latter half of the nineteenth century, controversy has raged over the subject matter of psychophysical laws. Originally, Fechner characterized psycho physics as the science describing the relation between physical magnitudes and the sensations these magnitudes produce in us. Today many psycho-physicists would deny that sensation is or could be a topic of psycho-physical investigation. I consider Savage's (1970) influential objections to the possibility of such an investigation and argue that they depend upon (i) holding psychophysics to higher standards than those to which we hold other sciences; and (ii) misrepresenting Fechner's stated goals for psychophysics.

By now, even the kid down the street must be familiar with the functionalist's response to type-identity physicalism. Mental kinds like pain, love, the belief that Madison sits on an isthmus, etc., are not identical to physical kinds because it's conceptually possible that entities physically distinct in kind from human beings experience pain, love, beliefs that Madison sits on an isthmus, etc. Type-identity physicalism, in short, is baselessly chauvinistic in its rejection of the possibility of nonhuman minds

Issues of identity and reduction have monopolized much of the philosopher of mind’s time over the past several decades. Interestingly, while investigations of these topics have proceeded at a steady rate, the motivations for doing so have shifted. When the early identity theorists, e.g. U. T. Place ( 1956 ), Herbert Feigl ( 1958 ), and J. J. C. Smart ( 1959 , 1961 ), fi rst gave voice to the idea that mental events might be identical to brain processes, they had as their intended foil the view that minds are immaterial substances. But very few philosophers of mind today take this proposal seriously. Why, then, the continued interest in identity and reduction? Th e concern, as philosophers like Hilary Putnam and Jerry Fodor have expressed it, is that a victory for identity or reduction is a defeat for psychology. For if minds are physical, or if mental events are physical events, then psychologists might as well disassemble their laboratories, making room for the neuroscientists and molecular biologists who are in a better position to explain those phenomena once misdescribed as “psychological.” Th e worry nowadays is not that locating thought in immaterial souls will make psychology intractable, but that locating thoughts in material brains will make it otiose.

Embodied cognition is one of the foremost areas of study and research in philosophy of mind, philosophy of psychology and cognitive science. The Routledge Handbook of Embodied Cognition is an outstanding guide and reference source to the key philosophers, topics and debates in this exciting subject and essential reading for any student and scholar of philosophy of mind and cognitive science. Comprising over thirty chapters by a team of international contributors, the Handbook is divided into six parts: Historical Underpinnings  Perspectives on Embodied Cognition  Applied Embodied Cognition: Perception, Language and Reasoning  Applied Embodied Cognition: Social and Moral Cognition and Emotion  Applied Embodied Cognition: Memory, Attention and Group Cognition    Meta-Topics. The early chapters of the Handbook cover empirical and philosophical foundations of embodied cognition, focusing on Gibsonian, phenomenological and cybernetic approaches. Subsequent chapters cover additional, important themes common to work in embodied cognition, incuding embedded , extended and enactive cognition as well as chapters on embodied cognition and empirical research in perception, language, reasoning, social and moral cognition, emotion, consciousness, memory and learning and development

A line of research within embodied cognition seeks to show that an organism’s body is a determinant of its conceptual capacities. Comparison of this claim of body determinism to linguistic determinism bears interesting results. Just as Slobin’s (1996) idea of thinking for speaking challenges the main thesis of linguistic determinism, so too the possibility of thinking for acting raises difficulties for the proponent of body determinism. However, recent studies suggest that the body may, after all, have a determining role in cognitive processes of sentence comprehension.

In the past twenty years, growing numbers of researchers have sought to steer cognitive science in a new direction. These researchers have emphasized the body’s role in cognition. Although the precise nature of this role often receives only vague description, perfectly clear is the idea that, whatever this role, the time has come for cognitive science to abandon old conceptions of the mind in favor of something new; and formerly trusted methods for its investigation must give way to novel techniques. This article will first present a brief description of the computational conception of mind against which embodied cognition typically positions itself. Following that will be a discussion of various research projects that embodied cognitivists take to challenge this computational conception. In conclusion, the chapter offers an assessment of the embodied challenge to computational cognitive science and considers its future prospects. Key words: cognition, embodied, computational, cognitive science.

Unifying traditional cognitive science is the idea that thinking is a process of symbol manipulation, where symbols lead both a syntactic and a semantic life. The syntax of a symbol comprises those properties in virtue of which the symbol undergoes rule-dictated transformations. The semantics of a symbol constitute the symbolsÕ meaning or representational content. Thought consists in the syntactically determined manipulation of symbols, but in a way that respects their semantics. Thus, for instance, a calculating computer sensitive only to the shape of symbols might produce the symbol Ô5Õ in response to the inputs Ô2Õ, Ô+Õ, and Ô3Õ. As far as the computer is concerned, these symbols have no meaning, but because of its program it will produce outputs that, to the user, Òmake senseÓ given the meanings the user attributes to the symbols.

By now, even the kid down the street must be familiar with the functionalist's response to type-identity physicalism. Mental kinds like pain, love, the belief that Madison sits on an isthmus, etc., are not identical to physical kinds because it's conceptually possible that entities physically distinct in kind from human beings experience pain, love, beliefs that Madison sits on an isthmus, etc. Type-identity physicalism, in short, is baselessly chauvinistic in its rejection of the possibility of nonhuman minds.

Prominent defenders of the extended cognition thesis have looked to evolutionary theory for support. Roughly, the idea is that natural selection leads one to expect that cognitive strategies should exploit the environment, and exploitation of the right sort results in a cognitive system that extends beyond the head of the organism. I argue that proper appreciation of evolutionary theory should create no such expectation. This leaves open whether cognitive systems might in fact bear a relationship to the environment that leads to their extension. *Received July 2009; revised January 2010. †To contact the author, please write to: Department of Philosophy, 5185 Helen C.
