Integration information theories posit that the integration of information is necessary and/or sufficient for consciousness. In this paper, we focus on three of the most prominent information integration theories: Information Integration Theory, Global Workspace Theory, and Attended Intermediate-Level Theory. We begin by explicating each theory and key concepts they utilize. We then argue that the current evidence indicates that the integration of information is neither necessary nor sufficient for consciousness. Unlike GWT and AIR, (...) IIT maintains that conscious experience is both necessary and sufficient for consciousness. We present empirical evidence indicating that simple features are experienced in the absence of feature integration and argue that it challenges IIT’s necessity claim. In addition, we challenge IIT’s sufficiency claim by presenting evidence from hemineglect cases and amodal completion indicating that contents may be integrated and yet fail to give rise to subjective experience. Moreover, we present empirical evidence from subjects with frontal lesions who are unable to carry out simple instructions and argue that they are irreconcilable with GWT. Lastly, we argue that empirical evidence indicating that patients with visual agnosia fail to identify objects they report being conscious of present a challenge to AIR’s necessity claim. (shrink)

Eigenfeatures are created by the principal component approach (PCA) used on objects described by a low-level code (i.e., pixels, Gabor jets). We suggest that eigenfeatures act like the flexible features described by Schyns et al. They are particularly suited for face processing and give rise to class-specific effects such as the other-race effect. The PCA approach can be modified to accommodate top-down constraints.

Intermediate‐level hypothesis (ILH) is the cornerstone of an adequate theory of consciousness. Ray Jackendoff's ILH is intended to apply to all sensory experience, including the experience of language. This chapter focuses on vision, because this is the most extensively studied sense. Jackendoff's views on vision were shaped by the seminal work of David Marr. Visual consciousness arises at an intermediate level, which occurs between discrete pixels and abstract models. The most compelling evidence for ILH comes (...) from studies of individuals with focal brain injuries. The findings from neuropsychology, electrophysiology, and functional imaging provide a strong case for ILH in vision. Jackendoff argues that ILH applies to all sense modalities. Research on the other senses lags woefully behind research on vision. On the strong version of Jackendoff's view, all consciousness resides at the intermediate level of perceptual systems. (shrink)

There is a view on consciousness that has strong intuitive appeal and empirical support: the intermediate-level theory of consciousness, proposed mainly by Ray Jackendoff and by Jesse Prinz. This theory identifies a specific “intermediate” level of representation as the basis of human phenomenal consciousness, which sits between high-level non-perspectival thought processes and low-level disjointed feature-detection processes in the perceptual and cognitive processing hierarchy. In this article, we show that the claim that (...) consciousness arises at an intermediate-level is true of some cognitive systems, but only in virtue of specific constraints on their active interactions with the environment. We provide ecological reasons for why certain processing levels in a cognitive hierarchy are privileged with respect to consciousness. We do this from the perspective of a prediction-error minimization model of perception and cognition, relying especially on the notion of active inference: the privileged level for consciousness depends on the specific dispositions of an organism concerned with inferring its policies for action. Such a level is indeed intermediate for humans, but this depends on the spatiotemporal resolution of the typical actions that a human organism can normally perform. Thus, intermediateness is not an essential feature of consciousness. In organisms with different action dispositions the privileged level or levels may differ as well. (shrink)

Conceptual space is proposed as an intermediate representation level between the psychological and the neurobiological levels of descriptions of appraisal and emotions. The main advantage of the proposed intermediate representation is that the appraisal and emotions dynamics are described by using the terms of geometry.

This paper develops an empirically motivated theory of visual consciousness. It begins by outlining neuropsychological support for Jackendoff's (1987) hypothesis that visual consciousness involves mental representations at an intermediate level of processing. It then supplements that hypothesis with the further requirement that attention, which can come under the direction of high level representations, is also necessary for consciousness. The resulting theory is shown to have a number of philosophical consequences. If correct, higher-order thought accounts, the (...) multiple drafts account, and the widely held belief that sensation precedes perception will all be found wanting. The theory will also be used to illustrate and defend a methodology that fills the gulf between functionalists who ignore the brain and neural reductionists who repudiate functionalism. (shrink)

There is an underappreciated disconnect between the ultimate values that lie at the heart of contemporary theories of distributive justice, and the practice of state institutions. State institutions deliver “intermediate goods” – goods such as health-care, education, housing, transportation, and the like – that are instrumental to a society being distributively just, but that do not in an of themselves constitute criteria of justice. Researchers who have emphasized the “social determinants of health” provide an insight that, when generalized, point (...) us in a direction that theorists of distributive justice should follow, that of attending not just to the instrinsic value of intermediate goods, but also to their causal contributions to realizing the values that theories of distributive justice make central. “Platforms”, which represent principle-driven attempts at designing compossible policies that attend both to the causal and to the intrinsic value of intermediate goods, should be given more importance within theories of distributive justice if such theories are to be policy-relevant, for they connect the ultimate values of these theories to the practices of state institutions.

False belief tasks have enjoyed a monopoly in the research on children’s development of a theory of mind. They have been granted this status because they promise to deliver an unambiguous assessment of children’s understanding of the representational nature of mental states. Their poor cousins, true belief tasks, have been relegated to occasional service as control tasks. That this is their only role has been due to the universal assumption that correct answers on true belief tasks are inherently ambiguous (...) regarding the level of the child’s understanding of mental states. It has also been due to the universal assumption that nothing in the child’s developing theory of mind would lead to systematically incorrect answers on true belief tasks. We review new findings that 4- and 5-year-olds do err, systematically and profoundly, on the true belief versions of all the extant belief tasks. This reveals an intermediate level of understanding in the development of children’s theory of mind. Researchers have been unaware of this intermediate level because it produces correct answers in false belief tasks. A simple two-task battery—one true belief task and one false belief task—is sufficient to remove the ambiguity from each task. The new findings show that children do not acquire an understanding of beliefs, and hence a representational theory of mind, until after 6 years of age, or 2 years later than most developmental psychologists have concluded. This raises the question of how to interpret other new findings that infants are able to pass false belief tasks. We review these new infant studies, as well as recent studies on chimpanzees, in light of older children’s failure on true belief tasks, and end with some speculation about how all of these new findings might be reconciled.

This article further explains and develops a recent, comprehensive semantic naturalization theory, namely the interactive indexing (II) theory as described in my 2008 Minds and Machines article Semantic Naturalization via Interactive Perceptual Causality (Vol. 18, pp. 527–546). Folk views postulate a concrete intentional relation between cognitive states and the worldly states they are about. The II theory eliminates any such concrete intentionality, replacing it with purely causal relations based on the interactive theory of perception. But intentionality (...) is preserved via purely abstract propositions about the world that index, or correlate with, appropriate cognitive states. Further reasons as to why intentionality must be abstract are provided, along with more details of an II-style account of representation, language use and propositional attitudes. All cognitive representation is explained in terms of classification or sorting dispositions indexed by appropriate propositions. The theory is also related to Fodor’s representational theory of mind, with some surprisingly close parallels being found in spite of the purely dispositional basis of the II theory. In particular, Fodor’s insistence that thinking about an item cannot be reduced to sorting dispositions is supported via a novel two-level account of cognition—upper level propositional attitudes involve significant intermediate processing of a broadly normative epistemic kind prior to the formation of sorting dispositions. To conclude, the weak intentional realism of the II theory—which makes intentional descriptions of the world dispensable—is related to Dennett’s ‘intentional stance’ view, and distinguished from strong (indispensable) intentional realist views. II-style dispositions are also defended. (shrink)

In approaching the question of whether groups of people can have cognitive capacities that are fundamentally different than the cognitive capacities of the individuals within the group, we lay out a Multiple, Interactive Levels of Cognitive Systems (MILCS) framework. The goal of MILCS is to explain the kinds of cognitive processes typically studied by cognitive scientists, such as perception, attention, memory, categorization, decision making, problem solving, and judgment. Rather than focusing on high-level constructs such as modules in an information (...) processing flow diagram or internal representations, MILCS focuses on mechanisms that allow systems to engage in flexible, adaptive behavior. Examples of these mechanisms are network structure-process pairs that: combine data from perception with top-down theories, achieve consistency and consensus through information exchange, selectively attend to information globally assessed as relevant, and develop specialized units from originally homogeneous networks through competition among the units. Two such systems are considered in some detail -- lateral inhibition within a network for selecting from a candidate set the option that is most attractive, and a diffusion process for accumulating evidence to reach a generally rapid and accurate decision. These system descriptions are aptly applied at multiple levels, including within and across people. These systems provide accounts that unify cognitive processes across multiple levels, can be expressed in a common vocabulary provided by network science, are inductively powerful yet appropriately constrained, and are applicable to a large number of superficially diverse cognitive systems. Given that people are typically highly motivated to participate in strong groups, cognitively resourceful people will tend to form groups that effectively employ cognitive systems at higher levels than the individuals. The impressive cognitive capacities of individual people do not eliminate the need to talk about group cognition. Instead, smart people generally form smart groups. (shrink)

Representationalism emerges unscathed from Pessoa et al.'s attack. They fail to undermine a key reason for its influence: it has the theoretical resources to explain many illusory visual experiences such as illusory contours and features. Furthermore, in attempting to undermine representationalism, the authors seem to erect an unduly inflated distinction between neural accounts of perception and personal-level accounts of perception.

In this article we review the basic idea of the “intermediate level” hypothesis about consciousness as proposed by Ray Jackendoff, then developed by Crick and Koch and finally by Prinz. According to this hypothesis, consciousness arises only at an intermediate-level, which lies between rough sensory inputs and the more abstract representations used, e.g., in object recognition. We aim at formulating a more specific hypothesis about a suitable conception of consciousness relative to the experience of language. We (...) claim that “linguistic consciousness”, namely an individual’s conscious experience engendered by the processing of linguistic information, cannot be identified only in the phenomenal role played by the phonological structure of language, contrary to what Jackendoff holds. Instead, we hypothesize that the top-down computational structure required for the very possibility of linguistic consciousness is determined by syntax. This hypothesis, we believe, avoids two problems with Jackendoff’s original account. (shrink)

In contemporary theories of language it is common to appeal to propositions as expressed by utterances of sentences. The aim of this paper is to question this idea, for as I argue, the relationship between sentences and propositions cannot be worked out in any rewarding way.

Charles W. Curtis is a prominent mathematician who has made important contributions to the field of representation theory. His textbooks in this field have been classics for a long time. In Pioneers of Representation Theory he has set out to present the historical development of the main ideas of the discipline, from the work of Georg Ferdinand Frobenius in the 1890s up to 1960. In addition to Frobenius, the book focuses mainly on three other “pioneers”: William (...) Burnside, Issai Schur, and Richard Brauer.Curtis states that his interest in the history of representation theory arose gradually, and jointly with that of Reiner, in the process of writing their textbooks. Thus, a main aim of the book is to show how the pioneers reached their important results while using only the mathematics then available to them. In order to do so, Curtis presents successive and thorough accounts of the works in which the new and seminal ideas of the pioneers were introduced and then developed. At the same time, however, he simplifies some of the original arguments by translating them into modern terminology.In an attempt to make the book appealing and accessible to a wider circle of potential readers, some of the necessary mathematics is explained. Thus Chapter 1 presents an introduction to the basic ideas and problems of nineteenth‐century algebra and number theory; later on, as the need arises, additional mathematical sections addressed to nonexperts are included. Of course, even this very clear presentation will be accessible only to readers with at least a graduate‐level knowledge of algebra.Curtis also attempts to provide some historical context. He is particularly concerned to clarify the main problems that the work of each of the mathematicians discussed here was originally meant to resolve. In a book of this kind this is surely one of the major benefits that the reader may expect to obtain.There are biographical sketches of the major figures involved, as well as additional information about other participants. Some illuminating documents are quoted, and Curtis supplies brief accounts of the mathematical traditions within which each of the pioneers was educated and worked. He acknowledges, however, that Pioneers of Representation Theory has only a limited claim as a work of historical research. He thus provides references to more historically oriented work that interested readers can consult. In particular, he mentions several articles by Thomas Hawkins; it should be stressed that much of Hawkins's work has recently been published in book form: Emergence of the Theory of Lie Groups: An Essay in the History of Mathematics, 1869–1926 . Curtis's and Hawkins's books complement each other in many important ways, and each should appeal to readers of the other.Charles Curtis has written an impressive, authoritative, and well‐informed book on a difficult subject. Mathematicians and historians of twentieth‐century mathematics with the relevant background will find it difficult but rewarding reading. Along the way, historiographical questions may arise. To what extent is it possible to translate, as Curtis does, the original proofs of the pioneers into more modern terminology and yet remain faithful to the sources? In most cases, however, it will require the technical expertise of the author himself to answer questions like this one properly. We can only hope that the firm starting point this book provides will lead Curtis to further historical research in this and related fields. (shrink)

Oaksford (2001) considers that the findings of Espino, Santamaria, and GarciaMadruga (2000a) could be explained by the Probability Heuristics Model (PHM) proposed by Chater and Oaksford (1999). He specifically voices three objections, the two main ones being based on the fact that PHM is not a theory about syllogism representation. If this is the case, we consider that PHM cannot explain our data, because most of them were registered before the participants evaluated the conclusion. We argue that only (...) a theory at the representational level can property explain these data. (shrink)

Disasters incurred by natural hazards affect young people most. Schools play a vital role in safeguarding the wellbeing of their pupils. Consideration of schools’ psychosocial influence on children may be vital to resilience-building efforts in disaster-vulnerable settings. This paper presents an evidence-based conceptualization of how schools are psychosocially meaningful for children and youth in disaster settings. Drawing on Social Representations and Place Attachment Theories, we explore the nature of group-based meaning-making practices and the meanings that emerge concerning school environments in (...) disaster settings. We contribute a novel understanding of how schools may mitigate psychosocial risk for young people by considering how schools are conceptualised at four levels: (1) as physical environment, (2) as social arena, (3) as a place with individual and (4) group-based significance. In each of these domains schools can foster disaster resilience in young people. This paper highlights the evidence concerning the functions of schools beyond their capacity as educational institutions, critically considering their social and physical functions in their communities. This evidence can inform stakeholders involved in disaster resilience building. (shrink)

Ontology, in its philosophical meaning, is the discipline investigating the structure of reality. Its findings can be relevant to knowledge organization, as well as models of knowledge can in turn offer relevant ontological suggestions. Several philosophers in time have pointed out that reality is structured into a series of integrative levels, like the physical, the biological, the mental, and the cultural one, and that each level plays as a base for the emergence of more complex ones. Among them, more (...) detailed theories of levels have been developed by Nicolai Hartmann and James K. Feibleman, and these have been considered as a source for structuring principles in bibliographic classification by both the Classification Research Group (CRG) and Ingetraut Dahlberg. CRG's analysis of levels and of their possible application to a new general classification scheme based on phenomena instead of disciplines, as it was formulated by Derek Austin in 1969, is examined in detail. Both benefits and open problems in applying integrative levels to bibliographic classification are pointed out. (shrink)

Organisms engage in various activities that are directed at objects, whether real or imagined. Such activities may be termed “intentional relations.” We present a four-level framework of social understanding that organizes the ways in which social organisms represent the intentional relations of themselves and other agents. We presuppose that the information available to an organism about its own intentional relations (or first person information) is qualitatively different from the information available to that organism about other agents’ intentional relations (or (...) third person information). However, through the integration of these two sources of information, it is possible to generate representations of intentional relations that are uniformly applicable to the activities of both self and other. The four levels of the framework differ in the extent to which such integration occurs and in the degree to which imagination is involved in generating these representations. Most animals exist at the lowest level, at which integration of first and third person sources of information does not occur. Of nonhuman species, only great apes exhibit social understanding at intermediate levels, at which integration of these sources of information provides uniform representations of intentional relations. Only humans attain the highest level, at which it is possible to represent intentional relations with mental objects. We propose that with the development of the imagination, children progress through three stages, equivalent to the later three levels of the framework. The abnormalities in social understanding of autistic individuals are hypothesized to result from a failure to develop integrated representations of intentional relations. (shrink)

Distributed Cognition and Integrational Linguistics have much in common. Both approaches see communicative activity and intelligent behaviour in general as strongly con- text-dependent and action-oriented, and brains as permeated by history. But there is some ten- sion between the two frameworks on three important issues. The majority of theorists of distributed cognition want to maintain some notions of mental representation and computa- tion, and to seek generalizations and patterns in the various ways in which creatures like us couple with (...) technologies, media, and other agents; many also want to offer explanations at subpersonal levels which may undercut the autonomy of personal-level accounts. In contrast, dominant views in integrational linguistics reject all invocation of representation, resist the explanatory search for similarity across contexts and moments, and see linguistics as a lay dis- cipline which should not offer explanations in terms alien to ordinary agents. On each of these issues, I argue that integrationists could move closer to the distributed cognition frame- work without losing the most important aspects of their view: integrationist criticisms of mainstream or classical theories can be respected while alliances with revised cognitivist views about representation, context, and explanation are developed.

In this paper we discuss the representational realist stance as a pluralist ontic approach to inter-theoretic relationships. Our stance stresses the fact that physical theories require the necessary consideration of a conceptual level of discourse which determines and configures the specific field of phenomena discussed by each particular theory. We will criticize the orthodox line of research which has grounded the analysis about QM in two metaphysical presuppositions —accepted in the present as dogmas that all interpretations must follow. (...) We will also examine how the orthodox project of "bridging the gap" between the quantum and the classical domains has constrained the possibilities of research, producing only a limited set of interpretational problems which only focus in the justification of "classical reality" and exclude the possibility of analyzing the possibilities of non-classical conceptual representations of QM. The representational realist stance introduces two new problems, namely, the superposition problem and the contextuality problem, which consider explicitly the conceptual representation of orthodox QM beyond the mere reference to mathematical structures and measurement outcomes. In the final part of the paper, we revisit, from a representational realist perspective, the quantum to classical limit and the orthodox claim that this inter-theoretic relation can be explained through the principle of decoherence.

In her landmark book, Language, Thought, and Other Biological Categories (Millikan1984),1 Ruth Garrett Millikan utilizes the idea of a biological function to solve philosophical problems associated with the phenomena of language, thought, and meaning. Language and thought are activities of biological organisms, according to Millikan, and we should treat them as such when trying to answer related philosophical questions. Of special interest is Millikan’s treatment of intentionality. Here Millikan employs the notion of a biological function to explain what it is (...) for one thing in nature, a bee dance (43), for example, to be about another, in this case, the location of a nectar source. My concern in this paper is to understand whether Millikan’s account of intentionality adequately explains how humans achieve reference, in language or thought, to individuals and groups in their environment. In bringing her theory of intentional content to bear on human activities, Millikan focuses largely on natural language. Thus, in what follows, I begin by laying out the biology-based principles that underlie Millikan’s theory of content, then proceed with an explanation of how the theory is to apply to natural language. As it appears, Millikan’s account of how content is determined for natural language terms and sentences rests on the determinacy of intentional content at the psychological level. This leads me to take a careful look at what Millikan says about the content of mental representations, in hopes of finding a sufficient basis there for the application of Millikan’s theory of content to natural language. Ultimately, I conclude that Millikan’s theory faces a problem of vacuity. If we approach the theory as a theory of intentional content, intended to explain the nature of reference, the theory is lacking in an extremely important respect: Millikan explains how it could be one of the biological functions of a mental or natural language term to refer, without telling us precisely what in the natural order constitutes the reference relation..

The sense of agency – the subjective feeling of being in control of our own actions – is one central aspect of the phenomenology of action. Computational models provided important contributions toward unveiling the mechanisms underlying the sense of agency in individual action. In particular, the sense of agency is believed to be related to the match between the actual and predicted consequences of our own actions. In the study of joint action, models are even more necessary to understand the (...) mechanisms underlying the development of coordination strategies and how the subjective experiences of control emerge during the interaction. In a joint action, we not only need to predict the consequences of our own actions; we also need to predict the actions and intentions of our partner, and to integrate these predictions to infer their joint consequences. Understanding our partner and developing mutually satisfactory coordination strategies are key components of joint action and in the development of the sense of joint agency. Here we discuss a computational architecture which addresses the sense of agency during intentional, real-time joint action. We first reformulate previous accounts of the sense of agency in probabilistic terms, as the combination of prior beliefs about the action goals and constraints, and the likelihood of the predicted movement outcomes. To look at the sense of joint agency, we extend classical computational motor control concepts - optimal estimation and optimal control. Regarding estimation, we argue that in joint action the players not only need to predict the consequences of their own actions, but also need to predict partner’s actions and intentions and to integrate these predictions to infer their joint consequences. As regards action selection, we use differential game theory – in which actions develop in continuous space and time - to formulate the problem of establishing a stable form of coordination and as a natural extension of optimal control to joint action. The resulting model posits two concurrent observer-controller loops, accounting for ‘joint’ and ‘self’ action control. The two observers quantify the likelihoods of being in control alone or jointly. Combined with prior beliefs, they provide weighing signals which are used to modulate the ‘joint’ and ‘self’ motor commands. We argue that these signals can be interpreted as the subjective sense of joint and self agency. We demonstrate the model predictions by simulating a sensorimotor interactive task where two players are mechanically coupled and are instructed to perform planar movements to reach a shared final target by crossing two differently located intermediate targets. In particular, we explore the relation between self and joint agency and the information available to each player about their partner. The proposed model provides a coherent picture of the inter-relation of prediction, control, and the sense of agency in a broader range of joint actions. (shrink)

In this paper I will investigate the possibility of defending the concept of ‘mental representation’ against certain contemporary critiques. Some authors, likeAnthony Chemero, argue that it is possible to explain offline actions with dynamic concepts. Hence, the dynamic discourse preempts the representational one. I doubt that this is a recommendable strategy. A form of representation is necessary, though one which is different from the classical one. Instead of eliminating the concept of representation (as radical dynamicists do) or (...) of splitting cognitive explanation in two separate discourses (as the adepts of the hybrid cognition version do), I consider that a dynamic concept of ‘representation’ is a better option. In my view, the higher level order resulted from the complex brain-body-environment coupling can be interpreted as being representational in nature. The dynamic paradigm involves a significant change concerning the intentional nature of representational states: the basic forms of representations are not maps of reality implemented as such in the brain, but limit conditions, attractors constraining the cognitive system’s evolution in its space state to reach its goals. On a certain threshold of complexity, the system develops stable attractors and attractor landscapes which could be interpreted as standing for something outside the system. This conception offers the advantages of avoiding preemptionargument, of unifying the cognitive explanation and, by its interscalar account, offers dynamic tools for building more complex artificial intelligent systems.

Teleosemantics attempts to explain the content of mental representations through an appeal to functions, and typically attributes function to selection history. The narrowest cases focus on only evolutionary fitness benefit through natural selection, while broader theories have come to accept multiple levels of selection, including those over the course of a lifetime such as neural selection. The precise way to define function has given rise to many debates over the content of hypothetical mental representations. In this paper, I argue that (...) defining function through the lens of Nikolas Tinbergen’s levels of analysis provides a valuable framework in organizing and analyzing teleological theories of function, and can advance the debate into a more organized discourse. In particular, after defining and defending them on theoretical grounds, I go through three classic teleosemantic debates about content ascription and function and attempt to organize them in a Tinbergian framework in order to demonstrate their general applicability, followed by two more examples from humans and primates in order to give insight on the role of each level of analysis in cases where we have more direct internal access to the content of such representations. I finally suggest that a pluralist viewpoint of the content of representations in complex organisms may be justified. I argue that in light of Tinbergen’s levels of analysis framework, teleosemantic theories of mental content can be more clearly discussed and advanced. (shrink)

One major fault line in foundational theories of cognition is between the so-called “representational” and “non-representational” theories. Is it possible to formulate an intermediate approach for a foundational theory of cognition by defining a conception of representation that may bridge the fault line? Such an account of representation, as well as an account of correspondence semantics, is offered here. The account extends previously developed agent-based pragmatic theories of semantic information, where meaning of an information state is (...) defined by its interface role, to a theory that accommodates a notion of representation and correspondence semantics. It is argued that the account can be used to develop an intermediate approach to cognition, by showing that the major sources of tension between “representational” and “non-representational” theories may be eased.

The traditional model of human cognition (TMHC) postulates an ontological and/or structural gap between conscious and unconscious mental representations. By and large, it sees higher-level mental processes as commonly conceptual or symbolic in nature and therefore conscious, whereas unconscious, lower-level representations are conceived as non-conceptual or sub-symbolic. However, experimental evidence belies this model, suggesting that higher-level mental processes can be, and often are, carried out in a wholly unconscious way and/or without conceptual representations, and that these can (...) be processed unconsciously. This entails that the TMHC, as well as the theories on mental representation it motivates and that in turn support it, is wrong. (shrink)

During the last decades, many cognitive architectures (CAs) have been realized adopting different assumptions about the organization and the representation of their knowledge level. Some of them (e.g. SOAR [35]) adopt a classical symbolic approach, some (e.g. LEABRA[ 48]) are based on a purely connectionist model, while others (e.g. CLARION [59]) adopt a hybrid approach combining connectionist and symbolic representational levels. Additionally, some attempts (e.g. biSOAR) trying to extend the representational capacities of CAs by integrating diagrammatical representations and (...) reasoning are also available [34]. In this paper we propose a reflection on the role that Conceptual Spaces, a framework developed by Peter G¨ardenfors [24] more than fifteen years ago, can play in the current development of the Knowledge Level in Cognitive Systems and Architectures. In particular, we claim that Conceptual Spaces offer a lingua franca that allows to unify and generalize many aspects of the symbolic, sub-symbolic and diagrammatic approaches (by overcoming some of their typical problems) and to integrate them on a common ground. In doing so we extend and detail some of the arguments explored by G¨ardenfors [23] for defending the need of a conceptual, intermediate, representation level between the symbolic and the sub-symbolic one. In particular we focus on the advantages offered by Conceptual Spaces (w.r.t. symbolic and sub-symbolic approaches) in dealing with the problem of compositionality of representations based on typicality traits. Additionally, we argue that Conceptual Spaces could offer a unifying framework for interpreting many kinds of diagrammatic and analogical representations. As a consequence, their adoption could also favor the integration of diagrammatical representation and reasoning in CAs. (shrink)

Although having conscious experiences is a fundamental feature of our everyday life, our understanding of what consciousness is is very limited. According to one of the main conclusions of contemporary philosophy of mind, the qualitative aspect of consciousness seems to resist functionalisation, i.e. it cannot be adequately defined solely in terms of functional or causal roles, which leads to an epistemic gap between phenomenal and scientific knowledge. Phenomenal qualities, then, seem to be, in principle, unexplainable in scientific terms. As a (...) reaction to this pessimistic conclusion it is a major trend in contemporary science of consciousness to turn away from subjective experiences and re-define the subject of investigations in neurological and behavioural terms. This move, however, creates a gap between scientific theories of consciousness, and the original phenomenon, which we are so intimately connected with. The thesis focuses on this gap. It is argued that it is possible to explain features of consciousness in scientific terms. The thesis argues for this claim from two directions. On the one hand, a specific identity theory is formulated connecting phenomenal qualities to certain intermediate level perceptual representations which are unstructured for central processes of the embedding cognitive system. This identity theory is hypothesised on the basis of certain similarities recognised between the phenomenal and the cognitive-representational domains, and then utilised in order to uncover further similarities between these two domains. The identity theory and the further similarities uncovered are then deployed in formulating explanations of the philosophically most important characteristics of the phenomenal domain—i.e. why phenomenal qualities resist functionalisation, and why the epistemic gap occurs. On the other hand, the thesis investigates and criticises existing models of reductive explanation. On the basis of a detailed analysis of how successful scientific explanations proceed a novel account of reductive explanation is proposed, which utilises so-called prior identities. Prior identities are prerequisites rather than outcomes of reductive explanations. They themselves are unexplained but are nevertheless necessary for mapping the features to be explained onto the features the explanation relies on. Prior identities are hypothesised in order to foster the formulation of explanatory claims accounting for target level phenomena in terms of base level processes—and they are justified if they help projecting base level explanations to new territories of the target level. The thesis concludes that the identity theory proposed is a prior identity, and the explanations of features of the phenomenal domain formulated with the aid of this identity are reductive explanations proper. In this sense, the thesis introduces the problem of phenomenal consciousness into scientific discourse, and therefore offers a bridge between the philosophy and the science of consciousness: it offers an approach to conscious experience which, on the one hand, tries to account for the philosophically most important features of consciousness, whereas, on the other hand, does it in a way which smoothly fits into the everyday practice of scientific research.

The representational content or subject matter of a picture is normally distinguished from various non-representational components of meaning involved in artworks, such as expressive, stylistic or intentional factors. However, I show how such non subject matter components may themselves be analyzed in content terms, if two different categories of representation are recognized--aspect indication for stylistic etc. factors, and normal representation for subject matter content. On the account given, the relevant kinds of content are hierarchically structured, with relatively unconceptualized (...) lower level aspectual contents encoding or symbolizing higher level conceptualized representational subject matter. Such an account is strongly supported by the latest findings of cognitive science regarding levels of conceptualization. The paper also demonstrates how the account given is compatible with the actual pictorial competence of normal viewers of visual artworks. (shrink)

Several conditions for being an intrinsically intentional agent are put forward. On a first level of intentionality the agent has representations. Two kinds are described: cued and detached. An agent with both kinds is able to represent both what is prompted by the context and what is absent from it. An intermediate level of intentionality is achieved by having an inner world, that is, a coherent system of detached representations that model the world. The inner world is (...) used, e.g., for conditional and counterfactual thinking. Contextual or indexical representations are necessary in order that the inner world relates to the actual external world and thus can be used as a basis for action. To have full-blown intentionality, the agent should also have a detached self-awareness, that is, be able to entertain self-representations that are independent of the context. (shrink)

The account extends previously developed agent-based pragmatic theories of semantic information, where meaning of an information state is (...) defined by its interface role, to a theory that accommodates a notion of representation and correspondence semantics. It is argued that the account can be used to develop an intermediate approach to cognition, by showing that the major sources of tension between “representational” and “non-representational” theories may be eased.

The aim of the thesis is to provide the foundations for a representation-based theory of meaning, i.e. a theory of meaning that encompasses the psychological level of cognitive representations. This is in opposition to the antipsychologist goals of the Fregean philosophy of language and represents the results of a joint analysis of multiple philosophical problems in contemporary philosophy of language, which, as argued in the tesis, stem from the lack of recognition of a cognitive level (...) in language. In the thesis, I first provide and argue a definition of cognitive/mental representations based on results in developmental psychology as well as theoretical considerations. Then, I use the definition to build upon it a richer theory of concepts and apply it to various philosophical conundra. The problems tackled include the problem of proper names (for which a solution is proposed that respects the post-Kripkean criticism), a unified meaning postulate for modalities and the epistemology and ontology of mathematical terms. The thesis concludes with a proposed application of the newly acquired framework to select social aspects of language use. (shrink)

DP hypothesis of Abney (1987), the syntactic unit that had formerly been known as noun phrase should in fact be analyzed as a phrase headed by a determiner, hence the label DP. Quite independently of this syntactic development, Partee (1987) proposed a type shifting paradigm for the semantic analysis of nominals (now called DPs). In Partee's proposal DPs are ambiguous between a referential reading of type e, a predicative reading of type et and a quantificational reading of type (et)t. DP (...) meanings can flexibly move between their different readings due to covert application of semantic operators. The present paper proposes some strong relationships between these syntactic and semantic paradigms. It is argued that the structure of the DP affects its semantics in that the NP level within the DP is purely predicative and the DP level itself is purely quantificational. However, the intermediate D' level is flexible between the predicate/quantifier semantic categories, due to the covert application of semantic operators at this level. Partee's assumption, adopted from Discourse Representation Theory and more traditional approaches in philosophical logic, that some DPs need to have a (discourse) referential reading, is withdrawn. Instead of Partee's type shifting operators between the three semantic categories she assumes, two operators are used between predicates and quantifiers. The choice function operation of Reinhart (1997) and Winter (1997) is used as a general operator from predicates to quantifiers. The minimum operator of Winter (1996) is used as a general operator from quantifiers to predicates. These two operations, referred to as category shifting operators , account for most of the Partee data and substantially extend the theory of flexibility to treat some intricate phenomena in the domains of coordination, plurality and scope.

Marr's seminal work laid out a program of research by specifying key questions for cognitive science at different levels of analysis. Because dynamic systems theory focuses on time and interdependence of components, DST research programs come to very different conclusions regarding the nature of cognitive change. We review a specific DST approach to cognitive-level processes: dynamic field theory. We review research applying DFT to several cognitive-level processes: object permanence, naming hierarchical categories, and inferring intent, that demonstrate (...) the difference in understanding of behavior and cognition that results from a DST perspective. These point to a central challenge for cognitive science research as defined by Marr—emergence. We argue that appreciating emergence raises questions about the utility of computational-level analyses and opens the door to insights concerning the origin of novel forms of behavior and thought. We contend this is one of the most fundamental questions about cognition and behavior. (shrink)

Face aux difficultés soulevées par le rapport de l'intellect à la chose intelligée — question qui suscite de nombreux débats aux confins des XIIIe et XIVe siècles —, Guillaume d'Ockham adopte une solution radicale: elle consiste à supprimer tout intermédiate entre l'acte d'intellection et la chose réelle, donnée dans sa présence singulière, ultime cause efficiente du procès d'émergence et d'élaboration de la connaissance. De ce fait, Guillaume d'Ockham rejette tout corrélat de la connaissance qui serait distinct de la chose même. (...) Cela revient à invalider aussi bien l'idée d'intentio in concreto que celle d'esse obiectivum. Sans faire l'unanimité, loin de là, la solution ockhamiste trouve des echos aussi bien chez des anglais tels que Gauthier Chatton ou Robert Holkot, que dans la pensée parisienne à partir de Jean Buridan. L'essentiel, de ce point de vue, est l'exigence de présence de la chose même dans le renvoi sémantique et dans le rapport de connaissance, par conséquent la détermination de l'objet — entendu comme ce qui fait face à l'intellect — à partir de la présence et de l'être donné, l'instauration d'une relation de causalité efficiente entre la chose et la connaissance.

In the framework of quantitative possibility theory, two representation modes were developed: logical-based representation in terms of quantitative possibilistic bases and graphical-based representation in terms of product-based possibilistic networks. This paper deals with logical and graphical representations of uncertain information using a quantitative possibility theory framework. We first provide a deep analysis of the relationships between these two forms of representational frameworks. Then, in the logical setting, we develop syntactic relations between penalty logic and quantitative (...) possibilistic logic. These translations are useful for different applications and are interesting for taking advantage of each format at the inferential level. We also provide an algorithm for reasoning with quantitative possibilistic logic. The algorithm takes inspiration from the syntactic relations between quantitative possibilistic logic bases and penalty logic. Finally, we provide experimental results that compar.. (shrink)

The Computational Theory of Mind (CTM) holds that cognitive processes are essentially computational, and hence computation provides the scientific key to explaining mentality. The Representational Theory of Mind (RTM) holds that representational content is the key feature in distinguishing mental from non-mental systems. I argue that there is a deep incompatibility between these two theoretical frameworks, and that the acceptance of CTM provides strong grounds for rejecting RTM. The focal point of the incompatibility is the fact that representational (...) content is extrinsic to formal procedures as such, and the intended interpretation of syntax makes no difference to the execution of an algorithm. So the unique 'content' postulated by RTM is superfluous to the formal procedures of CTM. And once these procedures are implemented in a physical mechanism, it is exclusively the causal properties of the physical mechanism that are responsible for all aspects of the system's behaviour. So once again, postulated content is rendered superfluous. To the extent that semantic content may appear to play a role in behaviour, it must be syntactically encoded within the system, and just as in a standard computational artefact, so too with the human mind/brain - it's pure syntax all the way down to the level of physical implementation. Hence 'content' is at most a convenient meta-level gloss, projected from the outside by human theorists, which itself can play no role in cognitive processing. (shrink)

Intermediate constructs are required as bridges between complex behaviors and realistic models of neural circuitry. For cognitive scientists in general, schemas are the appropriate functional units; brain theorists can work with neural layers as units intermediate between structures subserving schemas and small neural circuits.After an account of different levels of analysis, we describe visuomotor coordination in terms of perceptual schemas and motor schemas. The interest of schemas to cognitive science in general is illustrated with the example of perceptual (...) schemas in high-level vision and motor schemas in the control of dextrous hands.Rana computatrix, the computational frog, is introduced to show how one constructs an evolving set of model families to mediate flexible cooperation between theory and experiment. Rana computatrix may be able to do for the study of the organizational principles of neural circuitry what Aplysia has done for the study of subcellular mechanisms of learning. Approach, avoidance, and detour behavior in frogs and toads are analyzed in terms of interacting schemas. Facilitation and prey recognition are implemented as tectal-pretectal interactions, with the tectum modeled by an array of tectal columns. We show how layered neural computation enters into models of stereopsis and how depth schemas may involve the interaction of accommodation and binocular cues in anurans. (shrink)

One oft the most fascinating abilities of humans is the ability to become conscious of the own physical and mental states. In this systematic investigation of self-consciousness, a representational theory is developed that is able to distinguish between different levels of self-consciousness. The most basic levels are already present in such simple animals as ants. From these basic forms, which are also relevant for adult human self-consciousness, high-level self-consciousness including self-knowledge can arise. Thereby, the theory is not (...) only able to integrate developmental considerations but also to sharply distinguish different aspects of the complex phenomenon self-consciousness. Pathological breakdowns of these different aspects, as they can be found in schizophrenia, are explained by specific impairments on different levels of self-representation. In this way, the work shows that a naturalistic theory of self-consciousness is possible, if the analysis starts with very simple and basic mechanisms instead of starting on the »top of the iceberg«.

In various contexts and for various reasons, writers often define cognitive processes and architectures as those involving representational states and structures. Similarly, cognitive theories are also often delineated as those that invoke representations. In this paper, I present several reasons for rejecting this way of demarcating the cognitive. Some of the reasons against defining cognition in representational terms are that doing so needlessly restricts our theorizing, it undermines the empirical status of the representational theory of mind, and it encourages (...) wildly deflationary and explanatorily vacuous conceptions of representation. After criticizing this outlook, I sketch alternative ways we might try to capture what is distinctive about cognition and cognitive theorizing. (shrink)

A novel conceptual framework is introduced for the Complexity Levels Theory in a Categorical Ontology of Space and Time. This conceptual and formal construction is intended for ontological studies of Emergent Biosystems, Super-complex Dynamics, Evolution and Human Consciousness. A claim is defended concerning the universal representation of an item’s essence in categorical terms. As an essential example, relational structures of living organisms are well represented by applying the important categorical concept of natural transformations to biomolecular reactions and relational (...) structures that emerge from the latter in living systems. Thus, several relational theories of living systems can be represented by natural transformations of organismic, relational structures. The ascent of man and other living organisms through adaptation, is viewed in novel categorical terms, such as variable biogroupoid representations of evolving species. Such precise but flexible evolutionary concepts will allow the further development of the unifying theme of local-to-global approaches to highly complex systems in order to represent novel patterns of relations that emerge in super- and ultra-complex systems in terms of compositions of local procedures. Solutions to such local-to-global problems in highly complex systems with ‘broken symmetry’ might be possible to be reached with the help of higher homotopy theorems in algebraic topology such as the generalized van Kampen theorems (HHvKT). Categories of many-valued, Łukasiewicz-Moisil (LM) logic algebras provide useful concepts for representing the intrinsic dynamic ‘asymmetry’ of genetic networks in organismic development and evolution, as well as to derive novel results for (non-commutative) Quantum Logics. Furthermore, as recently pointed out by Baianu and Poli (Theory and applications of ontology, vol 1. Springer, Berlin, in press), LM-logic algebras may also provide the appropriate framework for future developments of the ontological theory of levels with its complex/entangled/intertwined ramifications in psychology, sociology and ecology. As shown in the preceding two papers in this issue, a paradigm shift towards non-commutative, or non-Abelian, theories of highly complex dynamics—which is presently unfolding in physics, mathematics, life and cognitive sciences—may be implemented through realizations of higher dimensional algebras in neurosciences and psychology, as well as in human genomics, bioinformatics and interactomics.

Over the last decade, attention has crawled from out of the shadows into the philosophical limelight with several important books and widely read articles. Carolyn Dicey Jennings has been a key player in the attention revolution, actively publishing in the area and promoting awareness. This book was much anticipated by insiders and does not disappoint. It is in no way redundant with respect to other recent monographs, covering both a different range of material and developing novel positions throughout. The book (...) might have been called The Attending Self, since Jennings defines attention as mental prioritization controlled by the self. This invocation of the self is among her central innovations, and may prove to be the main source of controversy. I will highlight points of contention here, but want to emphasize at the outset that the book is essential reading for anyone interested in attention. Jennings also contributes to a range of other debates, which will help a broader audience appreciate the importance this topic.After a brief introduction, Jennings provides “a philosophical landscape” of attention (chap. 2), tracing the concept through history. This is an invaluable achievement that will be welcomed by both newcomers and veterans. Jennings exhibits enormous breadth, covering areas that contemporary philosophers of mind tend to neglect: medieval philosophy, Buddhist thought, and phenomenology, to name a few. We also get perspectives on attention from core figures in the Western canon, such as Descartes, Locke, and Kant, as well as thinkers who gave the topic a more political inflection: Mary Wollstonecraft and W. E. B. DuBois. Jennings surveys contemporary literature as well, locating recent work in these older lineages. Some authors get more treatment later in the book (e.g., William James and Wayne Wu). Overall, Jennings provides the best overview of this history I have seen. She proves that attention is not a new topic, but one with deep roots and one that can inform current debates; Jennings draws on these roots throughout. I would love to see a companion piece surveying scientific theories, including “gain control” and “biased competition,” which get little airtime in the book. Some recent philosophical theories are under-explored as well, including Chris Mole’s concept of cognitive unison (Jennings discusses other aspects of his view), Carlos Montemayor and Harry Haladjian’s exploration of attention’s diversity (we get a touch of this), and my own proposal that attention is a gateway to working memory (not mentioned here). That said, no extant survey is more complete.Chapter 3 begins with the empirical claim that attention is regulated by slow brainwaves, and then takes up two issues. The first is mental causation. Endorsing moderate emergentism, Jennings argues that slow brain waves are causally efficacious even though they are not reducible to lower-level processes. (The metaphysics and neuroscience are presented accessibly, aided by three appendixes.) Second, Jennings argues that these slow brain waves indicate that attention is controlled by the self. As someone who was never moved by the mental causation problem—I don’t think overdetermination threatens efficacy—I would have welcomed more development of this second issue. For one thing, in linking attention to subjective control, Jennings eschews the idea that there can be purely “bottom-up” attention driven by stimulus features alone. This goes against the orthodoxy in attention science, and makes it hard for her to accommodate phenomena such as “pop-out,” or the commonsense idea that attention can be “captured” by a sudden flash or loud sound. For another thing, I wanted to hear more on why Jennings relates slow brain waves to the self. Does this include the slow waves that occur during deep sleep? Is there even such a thing as the self? Is there one self or many? How do slow brain waves reflect our interests, projects, values, self-conceptions, autobiographical narratives, or social identities? Does the social self invoked by Wollstonecraft and DuBois gain a foothold here? The whole chapter campaigns against metaphysical reductionism, but arrives at a perspective on the self that will strike some readers as highly reductive.In the fourth chapter, Jennings sheds further light on her conjecture that attention involves the self by advancing the thesis that attention endows sensory information with meaning. On the face of it, this may sound implausible. Object recognition, reading, and many other meaning-involving processes can take place outside of attention and outside of consciousness. But Jennings has a richer notion of “meaning” in mind. She develops the idea of “subject unity,” which is imposition of structure on perception that reflects the interests of the perceiving subject. This, she claims, is what brings perception into the space of reasons. Along the way, she has interesting observations about binding, feature integration, and demonstrative reference. The material is highly original, and Jennings’s postulation of interest-based perceptual organization is compelling. At the same time, one might wonder whether interests are really relegated to the ambit of attentional control. Consider the cocktail party effect, wherein one’s own name captures attention. This implies a preattentive filter that reflects our interests. Emotionally charged words, facial expressions, and dangerous objects also work this way, and social biases can operate preattentively as well. If these reflect our interests, then meaning may arise outside attention.Jennings’s fifth chapter explores the relationship between attention and consciousness. Some authors have argued that attention is necessary and sufficient for consciousness. Jennings focuses primarily on the necessity claim. She does not systematically review the empirical literature here, but she addresses some of the key findings, and effectively rebuts studies that allege to find consciousness outside attention. She does not rest her case there, however. Instead, she identifies a new class of examples that purport to establish the possibility of consciousness without attention. Her central example she calls “conscious entrainment,” which is what we experience when engaged in habitual or skilled activities. Other possible examples touched on in the chapter include hypervigilance in individuals with attention deficit hyperactivity disorder (ADHD), passive movie watching, dreaming, and “attentional neglect.” These states all involve intense focus, Jennings admits, but not attention. To some readers this may sound contradictory. Isn’t focus a kind of attention? Don’t these states of absorption involve stimulus selection and enhancement of relevant features, suppression of distractors, and other hallmarks of attention? Jennings says none of this is tantamount to attention. Recall that she thinks attention is controlled by the self. In these cases, we are invited to imagine that the self takes a passive role: control is either ceded to the world (movie watching) or to previously mastered routines (skills and habits). Thus, Jennings’s claim that there is no attention in these cases hangs on her contentious thesis that attention requires a controlling self. One might also push back by arguing that, in some of Jennings’s allegedly selfless examples, the self remains involved. Skilled activities and hypervigilance, for example, can reflect personal interests.Skills and hypervigilance get more airtime in chapter 6. There, Jennings turns to questions of responsibility—a neglected topic in attention research. The chapter begins with a manslaughter trial in which the teenage plaintiff was given a light sentence because the judge evidently believed that the teen’s ADHD compromised his ability to control his actions. The example may be a bit triggering for people who have a personal relationship with this diagnosis, but, putting that aside, Jennings uses it to introduce the important concept of attention-based control. With reduced control, Jennings argues, comes reduced responsibility. I am inclined to see ADHD as involving dysregulation of attention (difficulty disengaging and dividing attention, for example) rather than diminished attention, but that can still be characterized as an issue with control of attention; therefore ADHD still illustrates Jennings’s point that there is a link between responsibility and control of attention. This, it turns out, is only half of her story. Having argued for this link, one might expect Jennings to follow Wayne Wu, who contends that attention is necessary for action, and hence for responsibility. She does not. Instead, she says argues that responsibility can also arise in cases of “strategic automaticity.” This brings us back to skills. When skills are deployed, action is governed by learned pairings between stimuli and responses. The choice to exercise a skill requires attention, so attention is needed for being a responsible agent, but once a skill kicks in, attention is no longer required, and one can be held responsible for actions performed skillfully—thus attention is not required for responsibility tout court. Jennings addresses an opposing view (defended by Wu, Ellen Fridland, and Barbara Montero), according to which skills involve “automatic attention” rather than no attention. Jennings worries that this move will collapse the distinction between attention and other kinds of selection and filtering that occur throughout the nervous system, including the retina. She says that the attentional interpretation of skilled action is at odds with the lack of top-down reweighing of sensory inputs, regulated by lateral frontal cortex. These objections to automatic attention warrant response. My own view is that attention involves broadcasting to working memory, so retinal filtering is ruled out. Jennings’s insistence on top-down reweighing will not move those who believe attention can be purely bottom-up. For all that, I side with Jennings in wanting to allow for responsibility without attentional control. I think we can be responsible for implicit biases, for example. I also think attentional control is insufficient for responsibility, as when we act under duress.Jennings offers fresh perspective on the nature of attention, and its role in meaningful perception, consciousness, action, and responsibility. Each chapter can be read separately, but they hang together well, and each reflects her thesis that attention is essentially linked to the self. Though I am skeptical of that strong claim, we would do well to follow Jennings in regarding attention as interest-laden interface between mind and world. I look forward to a sequel in which attention is related to richer conceptions of identity, and where the political consequences of this link are actively explored. Meanwhile, one can hardly fault Jennings for covering too little. She tackles a remarkable range of topics, from metaphysics to ethics. Her arguments throughout demand response, repay careful study, and propel the field forward. (shrink)

Both inside and outside philosophy of science, the past 25 years has seen a remarkable increase in the epistemic importance attached to the role of background beliefs and values of agents engaged in cognitive inquiry. Emphasis on the role of background commitments has been beneficial in bringing philosophy of science back into closer relation with the varied forms of science. But at present there cannot be said to be any clear consensus among philosophers on issues of the theoretical status of (...) such commitments, or of their import upon conceptions of scientific meta-methodology.The situation worsens when one considers widespread suspicion today among many historicists and sociologists of science of the viability of philosophy of science as a normative enterprise. This marks the ground between normative epistemology and its critics. But to understand the skeptical attitude towards normative theory, one must attend to the background assumptions about normative discourse imbedded in logical empiricism, and in particular to the state of logical empiricist metascience just prior to the revolution of sorts that occurred in the 1960’s.
