In this paper, I claim that extant empirical data do not support a radically embodied understanding of the mind but, instead, suggest (along with a variety of other results) a massively representational view. According to this massively representational view, the brain is rife with representations that possess overlapping and redundant content, and many of these represent other mental representations or derive their content from them. Moreover, many behavioral phenomena associated with attention and consciousness are best explained by the coordinated activity (...) of units with redundant content. I finish by arguing that this massively representational picture challenges the reliability of a priori theorizing about consciousness. (shrink)

It is often claimed that the discovery of mirror neurons supports simulation theory (ST). There has been much controversy about this, however, as there are various competing models of the functional contribution of mirror systems, only some of which characterize mirroring as simulation in the sense required by ST. But a brief review of these models reveals that they all include simulation in some sense . In this paper, I propose that the broader conception of simulation articulated by neo-empiricist theories (...) of concepts can subsume the more specific conceptions of simulation presented by ST and by these other models, thereby offering a framework in which each of these models may play a role. According to neo-empiricism, conceptual thought in general involves simulation in the sense that it is grounded in sensory, motor, and other embodied systems (Barsalou, Behavioral and Brain Sciences , 22 , 577–609, 1999 , Philosophical Transactions of the Royal Society of London: Biological Sciences , 364 , 1281–1289, 2009 ; Barsalou et al., Trends in Cognitive Sciences , 7 (2), 84–91, 2003 ; Prinz 2002 , Mind & Language , 25 (5), 612–621, 2010 ; Glenberg and Robertson, Journal of Memory and Language , 43 , 379–401, 2000 ). Crucially, the term “simulation” here refers not to simulations of a target agent’s experience in the sense endorsed by simulation theory but to the activation of sensory, motor, affective, and introspective representations. This difference does not entail that neo-empiricism must be in competition with ST—indeed, I will propose that ST can be embedded as a special case within neo-empiricism. (shrink)

Western scholarship on early Chinese thought has tended to either dismiss the foundational role of metaphor or to see it as a uniquely Chinese mode of apprehending the world. This article argues that, while human cognition is in fact profoundly dependent on imagistic conceptual structures, such dependence is by no means a unique feature of Chinese thought. The article reviews empirical evidence supporting the claims that human thought is fundamentally imagistic; that sensorimotor schemas are often used to structure our understanding (...) of abstract concepts; that these schemas can be selectively combined to result in novel structures; and that there are inextricable connections between body, emotion, and thought in both everyday and philosophical cognition. It also provides a review of a recent trend where, explicitly or not, scholars from a variety of backgrounds have begun to take metaphor more seriously as a foundational bearer of philosophical meaning in early China.

Interactional expertise is said to be a form of knowledge achieved in a linguistic community and, therefore, obtained entirely outside practice. Supposedly, it is not or only minimally sustained by the so-called embodied knowledge. Here, drawing upon studies in contemporary neuroscience and cognitive psychology, I propose that ‘derived’ embodiment is deeply involved in competent language use and, therefore, also in interactional expertise. My argument consists of two parts. First, I argue for a strong relationship among language acquisition, language use and (...) the real world (i.e. the world accessible to the senses). Biological constraints in very early childhood anchor language to the body. These constraints are by-products of our evolutionary peculiarity that we gain because of our physical and psychological immaturity at birth. Thus, infancy is predominantly concerned with the bodily needs and experiences of the concrete while language acquisition takes place. Particular interest in the concrete furnishes our linguistic world and installs ‘concrete’ language as the principal constituent of competent language use. Second, I argue that well-established concrete language implicitly and explicitly elicits mental representations, namely partial reactivations of sensorimotor states that occur during experience. These are stepping stones by which we subsequently make sense of expressions in new linguistic areas. Like any competent language user, the interactional expert, therefore, prompts multimodal imagination and re-enacts concrete experiences when acquiring linguistic knowledge pertaining to a specialist field. Finally, I outline the characteristics of those imaginative powers to identify mechanisms that improve interactional expertise and discuss the obvious relation between interactional expertise and ordinary knowledge acquisition after the concrete language stage.

Fred Adams : 619–628, 2010) criticizes the theory of embodied cognition which holds that conceptual and linguistic thought is grounded in the brain’s perceptual and sensorimotor systems. Among other things, Adams claims that: EC is potentially committed to an implausible criterion of sentence meaningfulness; EC lacks claimed advantages over rival accounts of conceptual thought; relevant experimental data do not show constitutive, but only causal, involvement of perception in conception; and EC cannot account for the comprehension of abstract concepts. I respond (...) to Adams that: EC is not committed to an implausible criterion of meaningfulness, though it may be committed to holding that comprehension admits of degrees; EC does have its claimed advantages over rival views; the data do make a strong case for constitutive involvement and a broad and comprehensive EC approach probably can account for the comprehension of abstract concepts.

We perform conceptual acts throughout our daily lives; we are always judging others, guessing their intentions, agreeing or opposing their views and so on. These conceptual acts have phenomenological as well as formal richness. This paper attempts to correct the imbalance between the phenomenal and formal approaches to conceptualization by claiming that we need to shift from the usual dichotomies of cognitive science and epistemology such as the formal/empirical and the rationalist/empiricist divides—to a view of conceptualization grounded in the Indian (...) philosophical notion of “valid cognition”. Methodologically, our paper is an attempt at cross-cultural philosophy and cognitive science; ontologically, it is an attempt at marrying the phenomenal and the formal. (shrink)

Are concepts stable entities, unchanged from context to context? Or rather are they context-dependent structures, created on the fly? We argue that this does not constitute a genuine dilemma. Our main thesis is that the more a pattern of features is general and shared, the more it qualifies as a concept. Contextualists have not shown that conceptual structures lack a stable, general core, acting as an attractor on idiosyncratic information. What they have done instead is to give a contribution to (...) the comprehension of how conceptual structure organized around such a stable core can produce contextually appropriate representations on demand.

This review discusses recent work on foundational questions about concepts. The first of these questions is whether concepts are context-independent bodies of knowledge, or context-dependent constructs, created on the fly. The second question is whether concepts are abstract, amodal representations, or whether they are embedded within the sensory-motor system. I discuss these two questions in light of empirical data from psychology and neuroscience, as well as theoretical considerations, and examine their implications for theories of concepts.

For humans, the ability to communicate and use language is instantiated not only in the vocal modality but also in the visual modality. The main examples of this are sign languages and gestures. Sign languages, the natural languages of Deaf communities, use systematic and conventionalized movements of the hands, face, and body for linguistic expression. Co-speech gestures, though non-linguistic, are produced in tight semantic and temporal integration with speech and constitute an integral part of language together with speech. The articles (...) in this issue explore and document how gestures and sign languages are similar or different and how communicative expression in the visual modality can change from being gestural to grammatical in nature through processes of conventionalization. As such, this issue contributes to our understanding of how the visual modality shapes language and the emergence of linguistic structure in newly developing systems. Studying the relationship between signs and gestures provides a new window onto the human ability to recruit multiple levels of representation in the service of using or creating conventionalized communicative systems.

Mental recruitment of previous technological experience in conceptualizations of non-technological phenomena constitutes a specific kind of unintended cognitive effect of human technological activity. This paper discusses particular conceptual takes on a significant epistemic challenge faced by people in the Bronze Age eastern Mediterranean: that of understanding the factors and dynamics governing and allowing the most important celestial body to travel across the sky during the day. Textual sources, iconography and artefactual evidence in combination provide an outline of concrete conceptual solutions (...) to this challenge, which centre oncharioteering, i.e., the employment of light, horse-drawn vehicles for high-speed transport. These sources also inform on the actual, practical role played by this technological genre in the context of the eastern Mediterranean Bronze Age. The paper specifies a connection between the actual, mundane and social role of this form of vehicular technology in Bronze Age society, and the conceptualizations of an astronomical phenomenon to which it is recruited. This provides a specific case demonstrating how aspects of concrete, sensorimotor experience of technological activities, here the dynamics of vehicular transport, may ground associative conceptualization of empirically ill-specified phenomena. This, in turn, provides support for the general observation that the conceptual repertoires of individuals and collectives in particular historical contexts are influenced substantially by the experiential spectra associated with the specific ways of life into which they are born.

Recent evidence from cognitive neuroscience suggests that certain cognitive processes employ perceptual representations. Inspired by this evidence, a few researchers have proposed that cognition is inherently perceptual. They have developed an innovative theoretical approach that rests on the notion of perceptual simulation and marshaled several general arguments supporting the centrality of perceptual representations to concepts. In this article, I identify a number of weaknesses in these arguments and defend a multiple semantic code approach that posits both perceptual and non-perceptual representations.

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

Tacit knowledge is both a ubiquitous and puzzling notion, related to the idea of hidden assumptions. The puzzle is partly a result of the conflict between the idea that assumptions are in the mind and the apparent audience-relativity of the "fact" of possessing an assumption or of the tacit knowledge that is articulated. If we think of making the tacit explicit as constructing a certain kind of inference repairing explanation for a particular audience "on the fly" we come closer to (...) an explanation of what happens when we "make our tacit knowledge explicit." We can account for our capacity to construct such statements for particular audiences by reference to our non-conceptual capacities to understand others. This approach avoids problematic assumptions about shared representations that are common in cognitive science, and the equally problematic notion that tacit knowledge is sentence-like content that we retrieve when we articulate something based on our tacit knowledge.

The target article demonstrates how neurocognitive modellers should not be intimidated by challenges such as Jackendoff's and should explore neurally plausible implementations of linguistic constructs. The next step is to take seriously insights offlered by neuroscience, including the robustness allowed by analogue computation with distributed representations and the power of attractor dynamics in turning analogue into nearly discrete operations.

In this chapter we will discuss the concepts of “presence” (Inner Presence) and “social presence” (Co-presence) within a cognitive and ecological perspective. Specifically, we claim that the concepts of “presence” and “social presence” are the possible links between self, action, communication and culture. In the first section we will provide a capsule view of Heidegger’s work by examining the two main features of the Heideggerian concept of “being”: spatiality and “being with”. We argue that different visions from social and cognitive (...) sciences – Situated Cognition, Embodied Cognition, Enactive Approach, Situated Simulation, Covert Imitation - and discoveries from neuroscience – Mirror and Canonical Neurons - have many contact points with this view. In particular, these data suggest that our conceptual system dynamically produces contextualized representations (simulations) that support grounded action in different situations. This is allowed by a common coding – the motor code – shared by perception, action and concepts. This common coding also allows the subject for natively recognizing actions done by other selves within the phenomenological contents. In this picture we argue that the role of presence and social presence is to allow the process of self-identification through the separation between “self” and “other,” and between “internal” and “external”. Finally, implications of this position for communication and media studies are discussed by way of conclusion. (shrink)

Modern medicine has produced many successful theories concerning the causes of diseases. For example, we know that tuberculosis is caused by the bacterium Mycobacterium tuberculosis, and that scurvy is caused by a deficiency of vitamin C. This chapter discusses the nature of medical theories from the perspective of the philosophy, history, and psychology of science. I will review prominent philosophical accounts of what constitutes a scientific theory, and develop a new account of medical theories as representations of mechanisms that explain (...) disease. An account of the nature of medical theories should illuminate many aspects of the development and application of medical knowledge. Most importantly, it should contribute to understanding of medical explanation, both at the general level of causes of diseases and at the individual level of diagnosis of particular cases of a disease. Medical researchers seek to explain the causes of diseases such as tuberculosis, while physicians seek to identify diseases that explain symptoms such as fever. A medical theory such as the bacterial theory of tuberculosis provides good explanations at both the general and individual levels. The primary aim of this chapter is to show how these explanations work. A secondary aim is to show how an account of medical theories can shed light on other aspects of medical research and practice, including the nature of medical discovery, the process of evaluation of competing medical theories, and the ways in which effective treatments of disease depend on the development of good mechanistic theories about diseases.

Here are some of the most important discoveries in the history of medicine: blood circulation (1620s), vaccination, (1790s), anesthesia (1840s), germ theory (1860s), X- rays (1895), vitamins (early 1900s), antibiotics (1920s-1930s), insulin (1920s), and oncogenes (1970s). This list is highly varied, as it includes basic medical knowledge such has Harvey’s account of how the heart pumps blood, hypotheses about the causes of disease such as the germ theory, ideas about the treatments of diseases such as antibiotics, and medical instruments such (...) as X-ray machines. The philosophy of medicine should be able to contribute to understanding of the nature of discoveries such as these. The great originators of the field of philosophy of science were all concerned with the nature of scientific discovery, including Francis Bacon (1960), William Whewell (1967), John Stuart Mill (1974), and Charles Peirce (1931-1958). The rise of logical positivism in the 1930s pushed discovery off the philosophical agenda, but the topic was revived through the work of philosophers such as Norwood Russell Hanson (1958), Thomas Nickles (1980), Lindley Darden (1991, 2006), and Nancy Nersessian (1984). Scientific discovery has also become an object of investigations for researchers in the fields of cognitive psychology and artificial intelligence, as seen in the work of Herbert Simon, Pat Langley, and others (Langley et al., 1987; Klahr, 2000). Today, scientific September 14, 2009 discovery is an interdisciplinary topic at the intersection of the philosophy, history, and psychology of science. The aim of this chapter is to identify patterns of discovery that illuminate some of the most important developments in the history of medicine. I have used a variety of sources to identify forty great medical discoveries (Adler, 2004; Friedman and Friedland, 1998; Science Channel, 2006; Strauss and Strauss, 2006).. (shrink)

Despite its strengths, Leech et al.'s model fails to address the important benefits that derive from self-explanation and task feedback in analogical reasoning development. These components encourage explicit, self-reflective processes that do not necessarily link to knowledge accretion. We wonder, therefore, what mechanisms can be included within a connectionist framework to model self-reflective involvement and its beneficial consequences.

According to simulation or shared-substrates models of emotion recognition, our ability to recognize the emotions expressed by other individuals relies, at least in part, on processes that internally simulate the same emotional state in ourselves. The term “emotional expressions” is nearly synonymous, in many people's minds, with facial expressions of emotion. However, vocal prosody and whole-body cues also convey emotional information. What is the relationship between these various channels of emotional communication? We first briefly review simulation models of emotion recognition, (...) and then discuss neuroscientific evidence related to these models, including studies using facial expressions, whole-body cues, and vocal prosody. We conclude by discussing these data in the context of simulation and shared-substrates models of emotion recognition. (shrink)

To subscribe to the embodied mind (or embodiment) framework is to reject the view that an individual’s mind is realized by her brain alone. As Clark ( 2008a ) has argued, there are two ways to subscribe to embodiment: bodycentrism (BC) and the extended mind (EM) thesis. According to BC, an embodied mind is a two-place relation between an individual’s brain and her non-neural bodily anatomy. According to EM, an embodied mind is a threeplace relation between an individual’s brain, her (...) non-neural body and her non-bodily environment. I argue that BC can be given a weak and a strong interpretation, according to whether it accepts a functionalist account of the contribution of the non-neural body to higher cognitive functions and a computational account of the contents of concepts and the nature of conceptual processing. Thus, weak BC amounts to an incomplete version of EM. To accept a weak BC approach to concepts is to accept concept-empiricism. I raise four challenges for concept-empiricism and argue that what is widely taken as evidence for concept-empiricism from recent cognitive neuroscience could only vindicate weak BC if it could be shown that the non-neural body, far from being a tool at the service of the mind/brain, could be constitutive of the mind. If correct, EM would seem able to vindicate the claim that both bodily and non-bodily tools are constitutive of an individual’s mind. I scrutinize the basic arguments for EM and argue that they fail. This failure backfires on weak BC. One option left for advocates of BC is to endorse a strong, more controversial, BC approach to concepts. (shrink)

The literature contains a disconnect between accounts of how humans learn lexical semantic representations for words. Theories generally propose that lexical semantics are learned either through perceptual experience or through exposure to regularities in language. We propose here a model to integrate these two information sources. Specifically, the model uses the global structure of memory to exploit the redundancy between language and perception in order to generate inferred perceptual representations for words with which the model has no perceptual experience. We (...) test the model on a variety of different datasets from grounded cognition experiments and demonstrate that this diverse set of results can be explained as perceptual simulation (cf. Barsalou, Simmons, Barbey, & Wilson, 2003) within a global memory model. (shrink)

The Visual World Paradigm (VWP) presents listeners with a challenging problem: They must integrate two disparate signals, the spoken language and the visual context, in support of action (e.g., complex movements of the eyes across a scene). We present Impulse Processing, a dynamical systems approach to incremental eye movements in the visual world that suggests a framework for integrating language, vision, and action generally. Our approach assumes that impulses driven by the language and the visual context impinge minutely on a (...) dynamical landscape of attractors corresponding to the potential eye-movement behaviors of the system. We test three unique predictions of our approach in an empirical study in the VWP, and describe an implementation in an artificial neural network. We discuss the Impulse Processing framework in relation to other models of the VWP. (shrink)

Many kinds of creativity result from combination of mental representations. This paper provides a computational account of how creative thinking can arise from combining neural patterns into ones that are potentially novel and useful. We defend the hypothesis that such combinations arise from mechanisms that bind together neural activity by a process of convolution, a mathematical operation that interweaves structures. We describe computer simulations that show the feasibility of using convolution to produce emergent patterns of neural activity that can support (...) cognitive and emotional processes underlying human creativity.

Traditional views separate cognitive processes from sensory–motor processes, seeing cognition as amodal, propositional, and compositional, and thus fundamentally different from the processes that underlie perceiving and acting. These were the ideas on which cognitive science was founded 30 years ago. However, advancing discoveries in neuroscience, cognitive neuroscience, and psychology suggests that cognition may be inseparable from processes of perceiving and acting. From this perspective, this study considers the future of cognitive science with respect to the study of cognitive development.

Human cognition is unique in the way in which it relies on combinatorial (or compositional) structures. Language provides ample evidence for the existence of combinatorial structures, but they can also be found in visual cognition. To understand the neural basis of human cognition, it is therefore essential to understand how combinatorial structures can be instantiated in neural terms. In his recent book on the foundations of language, Jackendoff described four fundamental problems for a neural instantiation of combinatorial structures: the massiveness (...) of the binding problem, the problem of 2, the problem of variables, and the transformation of combinatorial structures from working memory to long-term memory. This paper aims to show that these problems can be solved by means of neural “blackboard” architectures. For this purpose, a neural blackboard architecture for sentence structure is presented. In this architecture, neural structures that encode for words are temporarily bound in a manner that preserves the structure of the sentence. It is shown that the architecture solves the four problems presented by Jackendoff. The ability of the architecture to instantiate sentence structures is illustrated with examples of sentence complexity observed in human language performance. Similarities exist between the architecture for sentence structure and blackboard architectures for combinatorial structures in visual cognition, derived from the structure of the visual cortex. These architectures are briefly discussed, together with an example of a combinatorial structure in which the blackboard architectures for language and vision are combined. In this way, the architecture for language is grounded in perception. Perspectives and potential developments of the architectures are discussed. Key Words: binding; blackboard architectures; combinatorial structure; compositionality; language; dynamic system; neurocognition; sentence complexity; sentence structure; working memory; variables; vision.

In this prcis we focus on phenomena central to the reaction against similarity-based theories that arose in the 1980s and that subsequently motivated the approach to semantic knowledge. Specifically, we consider (1) how concepts differentiate in early development, (2) why some groupings of items seem to form or coherent categories while others do not, (3) why different properties seem central or important to different concepts, (4) why children and adults sometimes attest to beliefs that seem to contradict their direct experience, (...) (5) how concepts reorganize between the ages of 4 and 10, and (6) the relationship between causal knowledge and semantic knowledge. The explanations our theory offers for these phenomena are illustrated with reference to a simple feed-forward connectionist model. The relationships between this simple model, the broader theory, and more general issues in cognitive science are discussed. (shrink)

Leech et al.'s model proposes representing relations as primed transformations rather than as structured representations (explicit representations of relations and their roles dynamically bound to fillers). However, this renders the model unable to explain several developmental trends (including relational integration and all changes not attributable to growth in relational knowledge). We suggest looking to an alternative computational model that learns structured representations from examples.

Humans and other animals are able not only to coordinate their actions with their current sensorimotor state, but also to imagine, plan and act in view of the future, and to realize distal goals. In this paper we discuss whether or not their future-oriented conducts imply (future-oriented) representations. We illustrate the role played by anticipatory mechanisms in natural and artificial agents, and we propose a notion of representation that is grounded in the agent’s predictive capabilities. Therefore, we argue that the (...) ability that characterizes and defines a true cognitive mind, as opposed to a merely adaptive system, is that of building representations of the non-existent, of what is not currently (yet) true or perceivable, of what is desired. A real mental activity begins when the organism is able to endogenously (i.e. not as the consequence of current perceptual stimuli) produce an internal representation of the world in order to select and guide its conduct goal-directed: the mind serves to coordinate with the future.

The emulation theory of representation is developed and explored as a framework that can revealingly synthesize a wide variety of representational functions of the brain. The framework is based on constructs from control theory (forward models) and signal processing (Kalman filters). The idea is that in addition to simply engaging with the body and environment, the brain constructs neural circuits that act as models of the body and environment. During overt sensorimotor engagement, these models are driven by efference copies in (...) parallel with the body and environment, in order to provide expectations of the sensory feedback, and to enhance and process sensory information. These models can also be run off-line in order to produce imagery, estimate outcomes of different actions, and evaluate and develop motor plans. The framework is initially developed within the context of motor control, where it has been shown that inner models running in parallel with the body can reduce the effects of feedback delay problems. The same mechanisms can account for motor imagery as the off-line driving of the emulator via efference copies. The framework is extended to account for visual imagery as the off-line driving of an emulator of the motor-visual loop. I also show how such systems can provide for amodal spatial imagery. Perception, including visual perception, results from such models being used to form expectations of, and to interpret, sensory input. I close by briefly outlining other cognitive functions that might also be synthesized within this framework, including reasoning, theory of mind phenomena, and language. Key Words: efference copies; emulation theory of representation; forward models; Kalman filters; motor control; motor imagery; perception; visual imagery. (shrink)

To explain how abstract concepts are grounded in sensory-motor experiences, several theories have been proposed. I will discuss two of these proposals, Conceptual Metaphor Theory and Situated Cognition, and argue why they do not fully explain grounding. A central idea in Conceptual Metaphor Theory is that image schemas ground abstract concepts in concrete experiences. Image schemas might themselves be abstractions, however, and therefore do not solve the grounding problem. Moreover, image schemas are too simple to explain the full richness of (...) abstract concepts. Situated cognition might provide such richness. Research in our laboratory, however, has shown that even for concrete concepts, sensory-motor grounding is task dependent. Therefore, it is questionable whether abstract concepts can be significantly grounded in sensory-motor processing. (shrink)
