This dissertation argues that mental representation is identical to phenomenal consciousness, and everything else that appears to be both mental and a matter of representation is not genuine mental representation, but either in some way derived from mental representation, or a case of non-mental representation.

The main thesis of this paper is twofold. In the first half of the paper, (§§1-2), I argue that there are two notions of mental representation, which I call objective and subjective. In the second part (§§3-7), I argue that this casts familiar tracking theories of mental representation as incomplete: while it is clear how they might account for objective representation, they at least require supplementation to account for subjective representation.

Over the past 50 years, philosophers and psychologists have perennially argued for the existence of analog mental representations of one type or another. This study critically reviews a number of these arguments as they pertain to three different types of mental representation: perceptual representations, imagery representations, and numerosity representations. Along the way, careful consideration is given to the meaning of “analog” presupposed by these arguments for analog mental representation, and to open avenues for future research.

The notion of a "mental representation" is, arguably, in the first instance a theoretical construct of cognitive science. As such, it is a basic concept of the Computational Theory of Mind, according to which cognitive states and processes are constituted by the occurrence, transformation and storage (in the mind/brain) of information-bearing structures (representations) of one kind or another.

Looks at accounts by Locke, Fodor, Dretske, and Millikan concerning the nature of mental representation, and discusses connectionism and representation.

Mental representation is one of core theoretical constructs within cognitive science and, together with the introduction of the computer as a model for the mind, is responsible for enabling the ‘cognitive turn’ in psychology and associated fields. Conceiving of cognitive processes, such as perception, motor control, and reasoning, as processes that consist in the manipulation of contentful vehicles representing the world has allowed us to refine our explanations of behavior and has led to tremendous empirical advancements. Despite the (...) central role that the concept plays in cognitive science, there is no unanimously accepted characterization of mental representation. Technological and methodological progress in the cognitive sciences has produced numerous computational models of the brain and mind, many of which have introduced mutually incompatible notions of mental representation. This proliferation has led some philosophers to question the metaphysical status and explanatory usefulness of the notion. This book contains state-of-the-art chapters on the topic of mental representation, assembling some of the leading experts in the field and allowing them to engage in meaningful exchanges over some of the most contentious questions. The collection gathers both proponents and critics of the concept of mental representation, allowing them to engage with topics such as the ontological status of representations, the possibility of formulating a general account of mental representation which would fit our best explanatory practices, and the possibility of delivering such an account in fully naturalistic terms.

The "teleosemantic" program is part of the attempt to give a naturalistic explanation of the semantic properties of mental representations. The aim is to show how the internal states of a wholly physical agent could, as a matter of objective fact, represent the world beyond them. The most popular approach to solving this problem has been to use concepts of physical correlation with some kinship to those employed in information theory (Dretske 1981, 1988; Fodor 1987, 1990). Teleosemantics, which tries (...) to solve the problem using a concept of biological function, arrived in the mid 1980s with ground-breaking works by Millikan (1984) and Papineau (1984, 1987).¹.

To the memory of Alan WhiteThe idea of mental representation occupies a rather prominent place in much contemporary discussion, both in philosophy and cognitive science, and not as a particularly controversial idea either. My reflections here, however, are intended to douse much of that discussion with some cold water. I should emphasize at the outset that I have no problems at all with the very idea of mental representation. What I find quite unsatisfactory is the philosophical (...) or doctrinal underpinning of much current theorising about it. Anyway, I shall suggest that talk of mental representation needs at least to be supplemented with, if not actually replaced by, a distinct notion of mental presentation, which cannot be reduced to it. But I start with the notion of an impression. (shrink)

Talk of ”mental representations” is ubiquitous in the philosophy of mind, psychology, and cognitive science. A slogan common to many different approaches says that representations ”stand in for” the things they represent. This slogan also attaches to most talk of "internal models" in cognitive science. We argue that this slogan is either false or uninformative. We then offer a new slogan that aims to do better. The new slogan ties the role of representations to the cognitive role played by (...) the deliverances of perception. After clarifying the new slogan and warding off some misunderstandings, we discuss how the new slogan still captures the seed of truth in the old, point to some specific misunderstandings that can be avoided, and then suggest some ways that the new slogan is useful in the project of giving a satisfying philosophical theory of representation.

Philosophers of mind tend to hold one of two broad views about mental representation: they are either robustly realist about mental representations, taking them to have determinate, objective content independent of attributors’ explanatory interests and goals, or they embrace some form of anti-realism, holding that mental representations are at best useful fictions. It is becoming increasingly clear that neither view is satisfactory. Realists disagree about the basis for objective content, and computational neuroscientists and psychologists, while making (...) widespread use of representational talk in articulating their theories, seem indifferent to the efforts of these philosophers to articulate a secure foundation for such talk, suggesting a disconnect between the preoccupations of philosophers of cognitive science and actual practice in these sciences. Fictionalists, for their part, must deny that representational mental states can be causes of cognition and behavior, and that appeal to mental representation can be genuinely explanatory, views that flatly contradict assumptions central to both science and everyday life. I develop and defend a distinctive ‘third way’ – a view I call a deflationary account of mental representation – that both resolves philosophical worries about content and best fits actual practice in science and everyday life. According to the deflationary account, appeal to mental representation does indeed purport to pick out causes of behavior, but the attribution of content to these causes is best understood as a pragmatically motivated gloss, justified in part by attributors’ explanatory interests and goals. Content plays an explanatory role in the deflationary account, but one quite different than that assumed by robust representational realists. (shrink)

This volume is a collection of new and previously published essays focusing on one of the most exciting and actively discussed topics in contemporary philosophy: naturalistic theories of mental content. The volume brings together important papers written by some of the most distinguished theorists working in the field today. Authors contributing to the volume include Jerry Fodor, Ruth Millikan, Fred Dretske, Ned Block, Robert Cummins, and Daniel Dennett.

This paper engages critically with anti-representationalist arguments pressed by prominent enactivists and their allies. The arguments in question are meant to show that the “as-such” and “job-description” problems constitute insurmountable challenges to causal-informational theories of mental content. In response to these challenges, a positive account of what makes a physical or computational structure a mental representation is proposed; the positive account is inspired partly by Dretske’s views about content and partly by the role of mental representations (...) in contemporary cognitive scientific modeling.

Conceptual atomists argue that most of our concepts are primitive. I take up three arguments that have been thought to support atomism and show that they are inconclusive. The evidence that allegedly backs atomism is equally compatible with a localist position on which concepts are structured representations with complex semantic content. I lay out such a localist position and argue that the appropriate position for a non-atomist to adopt is a pluralist view of conceptual structure. I show several ways in (...) which conceptual pluralism provides an advantage in satisfying the empirical and philosophical demands on a theory of conceptual structure and content. (shrink)

Mental representation is a metaphor. It has perhaps become so entrenched that it appears to have been frozen, and it is easy to lose sight of its metaphorical character. Literally, a representation is a re-presentation, a symbol that stands for something else because that thing can’t be with us. I send my parents photos of the grandchildren because e-mail is cheaper than air tickets. I consult a map of Adelaide to find the shortest route to the philosophy (...) department because wandering through the streets would take too much time. Perhaps in a similar sense I use words in this discussion because the very ideas in my head have no way of being transferred directly to yours. It is tempting to think that when you hear them thoughts in your head substitute in further processing for the sounds I produce or for the words they encode. But if I am right in what follows, we should resist this temptation.

This article engages the considerations of imagination in Kierkegaard and Ricoeur to argue for a moral dimension of the imagination and its objects. Imaginary objects are taken to be mental representations in images and narratives of people or courses of action that are not real in the sense that they are not actual, or have not yet happened. Three claims are made in the article. First, by drawing on the category of possibility, a conceptual distinction is established between imagination (...) and fantasy, (1) I claim that imagination has a moral dimension because it is engaged in considering real-life possibilities. Second, (2) drawing on Kierkegaard and Ricoeur, it is argued that mental representations of selfhood in imagination have a moral dimension because they essentially allow people to understand the development of agency in human selfhood by means of representations of would-be selves and narrative figurations of the self. Third, (3) mental representations of human selves have a moral dimension because they form important points of reference for moral orientations in the field of human praxis (moral pointers).

In Holism: A Shopper's Guide Fodor and LePore contend that there could be punctate minds; minds capable of being in only a single type of representational state. The Kantian idea that the construction of perceptual representations requires the synthesizing activity of the mind is invoked to argue against the possibility of punctate minds. Fodor's commitment to an inferential theory of perception is shown to share crucial assumptions with the Kantian view and hence to lead to the same conclusion. The argument (...) from the need for synthesis is then extended beyond the perceptual case to mental representation in general. (shrink)

The aim of this paper is to understand the functional role of mental representations and intentionality in skilled actions from a systems related perspective. Therefore, we will evaluate the function of representation and then discuss the cognitive architecture of skilled actions in more depth. We are going to describe the building blocks and levels of the action system that enable us to control movements such as striking the tennis ball at the right time, or grasping tools in manual (...) action. Based on this theoretical understanding the measurement of mental representations and related research results concerning mental representation in skilled action are presented in an overview. This leads to the question how mental representations develop and change during learning. Finally, to consolidate the functional understanding of mental representation in skilled action and interaction, we provide examples how to use the measurement of mental representation in humans to inform technical systems.

Many have urged that the biggest obstacles to a physicalistic understanding of consciousness are the problems raised in connection with the subjectivity of consciousness. These problems are most acutely expressed in consideration of the knowledge argument against physicalism. I develop a novel account of the subjectivity of consciousness by explicating the ways in which mental representations may be perspectival. Crucial features of my account involve analogies between the representations involved in sensory experience and the ways in which pictorial representations (...) exhibit perspectives or points of view. I argue that the resultant account of subjectivity provides a basis for the strongest response physicalists can give to the knowledge argument. (shrink)

Intentionality, mental representation, sensory perception and its reliability, sensory illusions, and the concomitant issue of epistemological skepticism are becoming an important cluster of related topics in research on medieval cognitive psychology. It is no wonder, because these topics are much more relevant to present-day discussions of cognition and sensory perception, as many of these issues remain unexplained to this date, and therefore any observations in these areas could still be of interest, while many other topics traditionally discussed in (...) studies on medieval philosophy have only historical value and gradually fade into oblivion. Although the two publications included in this review are not... (shrink)

Although much ink has been spilled on different aspects of legal concepts, the approach based on the developments of cognitive science is a still neglected area of study. The “mental” and cognitive aspect of these concepts, i.e., their features as mental constructs and cognitive tools, especially in the light of the developments of the cognitive sciences, is discussed quite rarely. The argument made by this paper is that legal concepts are best understood as mental representations. The piece (...) explains what mental representations are and why this view matters. The explanation of legal concepts, understood as mental representations is one of three levels of explanation within legal philosophy, but—as will be argued—it is the most fundamental level. This paper analyzes the consequences of such understanding of concepts used in the field of legal philosophy. Special emphasis is put on the current debate on the analogical or amodal nature of concepts. (shrink)

In this dissertation, I provide the logical foundation for a solution to the mind-body problem, a solution which is directly based upon Wilfrid Sellars' analogical theory of thought and sensation. Chapters I-IV are devoted to an interpretation, analysis, and constructive criticism of Sellars' notions of the inner thought episode and the sensing state. My analysis is offered in support of three general contentions: I argue that the postulation of inner thought episodes and sensing states is necessary for adequate explanations of (...) agent behavior; I hope to show how the analogical theory of inner thought episodes and sensing states actually generates a legitimate problem concerning the relationship between the mental and the physical; and I demonstrate the importance of the notion of analogy in philosophical theory construction. I suggest that the role of analogy provides the key for the solution to the mind-body problem. ;Chapter One is essentially introductory in nature. I offer an interpretation and reconstruction of Sellars' illustrative story entitled "The Jonesean Myth" . The "Myth" provides a suitable representation of Sellars' overall philosophy of mind. But perhaps more importantly, the "Myth" is a paradigm example of what I shall call the analogical method of inquiry, a method employed for the introduction of the notions of inner thought episodes and sensing states. In brief, I want to show how the "Myth" provides the logical basis for a theory adequate for explanations of the mental activity of agents. ;Chapters II and III are closely related. In Chapter II, I present a theory of linguistic representation which will serve as the analogical base for the introduction and characterization of the inner thought episode. In Chapter III, I develop the notion of the inner thought episode , and I examine its nature and status as a theoretical construct. Chapters II and III are thus related by the Sellarsian thesis that the concept of mental representation is to be understood in terms which apply, primarily, to characterizations of the features of the linguistic framework presented in Chapter II. ;In Chapter IV, I argue, again following Sellars' lead, that the explication of the notion of the perceptual thought episode requires the introduction of a second distinct sort of inner episode, namely, that of the sense experience or sensing state. The argument offered in Chapter IV is designed to show that sensing states are theoretical constructs, the reference to which is essential for explanations concerning the occurrence and nature of perceptual representations. Sensing states are introduced and characterized by an analogical extension of families of predicates which are suitable for the identification and description of ordinary physical objects . ;In Chapter V, I propose a solution to the mind-body problem, as the latter is generated by the analysis given to the thought episode and the sensing state . In general terms, I argue that any purported solution to the mind-body problem must provide an explanatory basis for agent behavior, and it is for this reason that I reject "reductionistic" theories of mind of the kind represented by logical behaviorism, type-identity physicalism, and Turing Machine functionalism. My solution, instead, involves a commitment to what I shall call token physicalism, a thesis which is contingent upon the development of a theory of neurophysiology which is rich enough to capture, in an analogical sense, both the intentional features of the thought episode, and the occurrent-like qualities which are exemplified by the sensing state.

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«.

According to some views, natural language suffers from underdeterminacy, but thought doesn’t. According to the underdeterminacy claim, sentence types underdetermine the truth-conditions of sentence tokens. In particular, the semantics of a predicate type seems to underdetermine the satisfaction conditions of its tokens. By contrast, mental representation-types are supposed to determine the truth-conditions of its tokens. In this paper I critically examine these mixed views. First, I argue that the arguments supporting the indispensability of including in one’s theory (...) class='Hi'>mental representations that are free of the underdeterminacy exhibited by natural language are not sound. As a result, the possibility that mental representation-types are as underdetermined as natural language sentence-types has not been ruled out. Second, I argue that Carston’s ad hoc concept-types are as underdetermined as word-types. I finish by arguing that mental representations are also underdetermined in a second sense—mental representation-tokens only determine a partial function from possible worlds to truth-values.

The contributors are well-established scholars in the field who build on their previous work, and most advance an original argument in these essays.

As editor Gyula Klima points out, intentionality plays a role in non-cognitive as well as cognitive processes for the medievals. But when these thinkers attempted to explain the.. (shrink)

Various theories of moral cognition posit that moral intuitions can be understood as the output of a computational process performed over structured mental representations of human action. We propose that action plan diagrams—“act trees”—can be a useful tool for theorists to succinctly and clearly present their hypotheses about the information contained in these representations. We then develop a methodology for using a series of linguistic probes to test the theories embodied in the act trees. In Study 1, we validate (...) the method by testing a specific hypothesis (diagrammed by act trees) about how subjects are representing two classic moral dilemmas and finding that the data support the hypothesis. In Studies 2–4, we explore possible explanations for discrete and surprising findings that our hypothesis did not predict. In Study 5, we apply the method to a less well‐studied case and show how new experiments generated by our method can be used to settle debates about how actions are mentally represented. In Study 6, we argue that our method captures the mental representation of human action better than an alternative approach. A brief conclusion suggests that act trees can be profitably used in various fields interested in complex representations of human action, including law, philosophy, psychology, linguistics, neuroscience, computer science, robotics, and artificial intelligence.

Situation theorists such as John Barwise, John Etchemendy, John Perry and François Recanati have put forward the hypothesis that linguistic representations are situated in the sense that they are true or false only relative to partial situations which are not explicitly represented as such. Following Recanati's lead, I explore this hypothesis with respect to mental representations. First, I introduce the notion of unarticulated constituent, due to John Perry. I suggest that the question of whether there really are such constituents (...) should divide in two issues, one concerning language and the other concerning thought. Then I formulate a dilemma that any friend of cognitive unarticulated constituents must face: alleged unarticulated constituents seem to be either articulated or non-constituents after all. The dilemma is strengthened by the fact that unarticulated constituents cannot be inferentially relevant. In §4, three constraints on entertaining situated representations are spelled out. First, although the situation within which one is immersed is not represented as such, there must be cognitive facts that make immersion possible, and explain why one is implicitly related to a particular situation as opposed to another. Second, the move from a given representation to one which articulates the situation requires the capacity to contrast the latter with others in the same range. Third, I suggest that conceptual representations differ from non-conceptual ones in the permanent possibility of detachment that they allow. I then illustrate how these constraints work in three sorts of cases. In the first, thoughts like It's raining and It's over are implicitly related to their situations via some practical capacity of keeping track of particular places or times. In the second sort of cases, the relevant situations are not given, but stipulated, like in In Constance, it's raining. Cases of the third sort are those in which an unarticulated constituent is relevant to a whole system of representations, for instance the perceptual system. In the last section, I use the notion of ad hoc representation to defend the cognitive application of situation semantics against an important objection. (shrink)

: Fodor’s view of the mind is thoroughly computational. This means that the basic kind of mental entity is a “discursive” mental representation and operations over this kind of mental representation have broad architectural scope, extending out to the edges of perception and the motor system. However, in multiple epochs of his work, Fodor attempted to define a functional role for non-discursive, imagistic representation. I describe and critique his two considered proposals. The first view (...) says that images play a particular kind of functional role in certain types of deliberative tasks. The second says that images are solely restricted to the borders of perception, and act as a sort of medium for the fixing of conceptual reference. I argue, against the first proposal, that a broad-scope computationalism such as Fodor’s renders images in principle functionally redundant. I argue, against the second proposal, that empirical evidence suggests that non-discursive representations are learned through perceptual learning, and directly inform category judgments. In each case, I point out extant debates for which the arguments are relevant. The upshot is that there is motivation for limited scope computationalism, in which some, but not all, mental processes operate on discursive mental representations. Keywords: Computational Theory of Mind; Mental Representation; Perception; Mental Image; Jerry Fodor Fodor e le rappresentazioni mentali come immagini Riassunto: La concezione della mente di Fodor è rigorosamente computazionale, ossia le entità mentali di base sono rappresentazioni mentali “discorsive”. Le operazioni su queste rappresentazioni hanno un fine architettonico ampio, che va fino ai confini della percezione e del sistema motorio. In periodi diversi del suo lavoro, Fodor ha proposto due modi per definire un ruolo funzionale per la rappresentazione non-discorsiva come immagine. Tratterò criticamente entrambi. Per il primo, le immagini giocano un particolare tipo di ruolo funzionale in certi tipi di compiti deliberativi, mentre, per il secondo, sono relegate unicamente ai confini della percezione, agendo come medium per fissare il riferimento concettuale. Contro il primo sosterrò che un computazionalismo così ampio come quello di Fodor rende le immagini in principio funzionalmente ridondanti. Contro il secondo sosterrò che l’evidenza empirica suggerisce che le rappresentazioni non-discorsive vengono apprese percettivamente, agendo direttamente sui giudizi di categorizzazione. In entrambi i casi considererò gli argomenti più rilevanti nel dibattito corrente. Si vedrà che ci sono buone ragioni in favore di un computazionalismo più limitato, in cui alcuni processi mentali operano su rappresentazioni mentali discorsive.

A sentence like every circle is blue might be understood in terms of individuals and their properties or in terms of a relation between groups. Relatedly, theorists can specify the contents of universally quantified sentences in first-order or second-order terms. We offer new evidence that this logical first-order vs. second-order distinction corresponds to a psychologically robust individual vs. group distinction that has behavioral repercussions. Participants were shown displays of dots and asked to evaluate sentences with each, every, or all combined (...) with a predicate. We find that participants are better at estimating how many things the predicate applied to after evaluating sentences in which universal quantification is indicated with every or all, as opposed to each. We argue that every and all are understood in second-order terms that encourage group representation, while each is understood in first-order terms that encourage individual representation. Since the sentences that participants evaluate are truth-conditionally equivalent, our results also bear on questions concerning how meanings are related to truth-conditions. (shrink)

Commonsense psychology and cognitive science both regularly assume the existence of representational states. I propose a naturalistic theory of representation sufficient to meet the pretheoretical constraints of a "folk theory of representation", constraints including the capacities for accuracy and inaccuracy, selectivity of proper objects of representation, perspective, articulation, and "efficacy" or content-determined functionality. The proposed model states that a representing device is a device which changes state when information is received over multiple information channels originating at a (...) single source. The changed state of a representing device is a representation. The unitary information source which would give rise to the information impinging on the representing device, and hence, give rise to the representation, is the content of the representation. The model meets the pretheoretic constraints, and also conforms to available neurobiological data for two invertebrate species. (shrink)

The book makes a direct contribution to the connection between phenomenology and cognitive science.

Experimental studies on polysemy have come to contradictory conclusions on whether words with multiple senses are stored as separate or shared mental representations. The present study examined the semantic relatedness and semantic similarity of literal and non-literal (metonymic and metaphorical) senses of three word classes: nouns, verbs, and adjectives. Two methods were used: a psycholinguistic experiment and a distributional analysis of corpus data. In the experiment, participants were presented with 6–12 short phrases containing a polysemous word in literal, metonymic, (...) or metaphorical senses and were asked to classify them so that phrases with the same perceived sense were grouped together. To investigate the impact of professional background on their decisions, participants were controlled for linguistic vs. non-linguistic education. For nouns and verbs, all participants preferred to group together phrases with literal and metonymic senses, but not any other pairs of senses. For adjectives, two pairs of senses were often grouped together: literal with metonymic, and metonymic with metaphorical. Participants with a linguistic background were more accurate than participants with non-linguistic backgrounds, although both groups shared principal patterns of sense classification. For the distributional analysis of corpus data, we used a semantic vector approach to quantify the similarity of phrases with literal, metonymic, and metaphorical senses in the corpora. We found that phrases with literal and metonymic senses had the highest degree of similarity for the three word classes, and that metonymic and metaphorical senses of adjectives had the highest degree of similarity among all word classes. These findings are in line with the experimental results. Overall, the results suggest that the mental representation of a polysemous word depends on its word class. In nouns and verbs, literal and metonymic senses are stored together, while metaphorical senses are stored separately; in adjectives, metonymic senses significantly overlap with both literal and metaphorical senses.
