Précis of 'The Origin of Concepts'

A theory of conceptual development must specify the innate representational primitives, must characterize the ways in which the initial state differs from the adult state, and must characterize the processes through which one is transformed into the other. The Origin of Concepts (henceforth TOOC) defends three theses. With respect to the initial state, the innate stock of primitives is not limited to sensory, perceptual, or sensorimotor representations; rather, there are also innate conceptual representations. With respect to developmental change, conceptual development consists of episodes of qualitative change, resulting in systems of representation that are more powerful than, and sometimes incommensurable with, those from which they are built. With respect to a learning mechanism that achieves conceptual discontinuity, I offer Quinian bootstrapping. TOOC concludes with a discussion of how an understanding of conceptual development constrains a theory of concepts.     

Unconscious Representations 1: Belying the Traditional Model of Human Cognition

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.     

感知运动信息在概念表征中的作用

研究概念的表征问题对理解概念的本质非常重要,传统认知和具身认知视角下的概念表征理论争议的焦点在于感觉运动信息在表征中的作用。传统认知视角下的离身认知认为感知觉运动信息会转化成抽象的符号,概念表征不包含感知觉运动信息。概念表征的具身观点认为感知觉运动信息是概念表征的基础。对感知运动信息在概念表征中起作用这一命题已经达成共识。未来研究应该关注感知运动信息起作用的机制,以及抽象概念表征等问题,进一步完善发展概念表征理论。     

Meaning structures and mental representations

This paper argues for a distinction between meaning structure and mental representation, and presents the outlines of a theoretical model of their interrelationship. Meaning structures are defined as structures in the human mind/brain which develop as the combined result of genetic predispositions and individual experience, and lead to relatively stable patterns of perceiving, thinking, feeling, behaving, etc. Mental representation is defined as the aspect of mental processes which involves imagining and thinking of things that are not perceptually present. It is suggested that the mind includes a central network of meaning structures (CNMS) for the storage of information, and a number of other subsystems (e.g., perceptual systems, behavioral systems, and a verbal system) for the processing of externally and internally generated information. Against the dual-coding theory, it is argued that there is one code for the long-term storage of information, but several codes for the processing of information. Mental representations are seen as products of activation that is spread from the CNMS to more peripheral systems. The spread of activation from the CNMS to perceptual systems results in mental imagery; when activation spreads to the verbal system the result is conceptual thinking; and when activation spreads to behavioral systems it produces intentions. It is argued that this conceptual model can help to solve some basic theoretical problems that have plagued cognitive psychology.     

感觉运动模拟隐喻理论的形成与发展

感觉运动模拟理论属于概念隐喻理论范畴,是经典概念隐喻理论的最新发展。感觉运动模拟隐喻理论认为概念隐喻的具身效应并不一定要建立在以往的经验之上,与感觉运动信息无关的抽象概念通过快速学习建立的隐喻也具有了具身效应,没有以往经验为基础的抽象概念也能引起感觉运动的模拟。除了感觉运动模拟隐喻理论的主要观点之外,文章还介绍了该理论的形成与发展的过程。并通过与经典概念隐喻理论的对比,提出感觉运动模拟隐喻理论存在的优势与局限性     

生成认知：理论基础与实践走向

生成认知是具身认知思潮中的一个新取向。它主张认知是通过身体活动“生成的” (enacted)。认知的起点不是一个怎样精确表征世界的信息加工问题, 而是行动者在情境中怎样利用知觉来指导自己的行动。认知不是通过精确的心理表征“恢复”世界, 而是通过知觉引导的行动“生成”或“造就”一个自己的世界。认知是具身的行动, 认知结构形成于经常和反复出现的感觉运动模式, 与身体构造和身体活动具有深刻连续性。梅洛·庞蒂的身体现象学对生成认知具有深刻影响。同时, 詹姆斯、杜威等人的实用主义哲学对于实践行动的强调也深刻影响了生成认知。这种认知观强调了“行动”对心智的意义, 引发许多争议, 也促进了心理学研究范式的转变。     

A heterodox defense of the actualist higher-order thought theory

I defend the actualist higher-order thought theory against four objections. The first objection contends that the theory is circular. The second one contends that the theory is unable to account for the alleged epistemic position we are in with respect to our own conscious mental states. The third one contends that the theory is unable to account for the evidence we have for the proposition that all conscious mental states are represented. The fourth one contends that the theory does not accommodate the intimacy we have with our own conscious mental states. To some extent, my defense will be heterodox, in the sense that I will show that some objections are satisfactorily answerable even if we concede to the objectors a point that higher-order theorists do not seem to be willing to concede, that is, that the theory is the result of conceptual analysis.

     

Fantasy,defense, and the representational world

This paper discusses the manipulation of mental representations, particularly in relation to the psychoanalytic concepts of conscious or unconscious fantasy. A distinction is made between the unconscious phenomenal (experiential) aspect of representations and the nonexperiential, quasi-structural aspect. The concept of the representational world is described and elaborated, and its development is seen as a consequence of the infant's interaction with itself and the external world. Processes such as identification and projection can be seen in terms of changes in self and object representations, and the same is true for all the mechanisms of defense. The content of unconscious wishes is transformed, by use of such mechanisms, into representations that are acceptable to consciousness. Major transformations of unconscious representational content occur in the process of creating unconscious (preconscious) fantasy, and further transformations are frequently needed before such (preconscious) fantasies are permitted access to consciousness. The concept of projective identification is considered in the light of the ideas put forward in the paper.     

Linguistic Distributional Knowledge and Sensorimotor Grounding both Contribute to Semantic Category Production

The human conceptual system comprises simulated information of sensorimotor experience and linguistic distributional information of how words are used in language. Moreover, the linguistic shortcut hypothesis predicts that people will use computationally cheaper linguistic distributional information where it is sufficient to inform a task response. In a pre-registered category production study, we asked participants to verbally name members of concrete and abstract categories and tested whether performance could be predicted by a novel measure of sensorimotor similarity (based on an 11-dimensional representation of sensorimotor strength) and linguistic proximity (based on word co-occurrence derived from a large corpus). As predicted, both measures predicted the order and frequency of category production but, critically, linguistic proximity had an effect above and beyond sensorimotor similarity. A follow-up study using typicality ratings as an additional predictor found that typicality was often the strongest predictor of category production variables, but it did not subsume sensorimotor and linguistic effects. Finally, we created a novel, fully grounded computational model of conceptual activation during category production, which best approximated typical human performance when conceptual activation was allowed to spread indirectly between concepts, and when candidate category members came from both sensorimotor and linguistic distributional representations. Critically, model performance was indistinguishable from typical human performance. Results support the linguistic shortcut hypothesis in semantic processing and provide strong evidence that both linguistic and grounded representations are inherent to the functioning of the conceptual system.

Concepts as Semantic Pointers: A Framework and Computational Model

The reconciliation of theories of concepts based on prototypes, exemplars, and theory‐like structures is a longstanding problem in cognitive science. In response to this problem, researchers have recently tended to adopt either hybrid theories that combine various kinds of representational structure, or eliminative theories that replace concepts with a more finely grained taxonomy of mental representations. In this paper, we describe an alternative approach involving a single class of mental representations called “semantic pointers.” Semantic pointers are symbol‐like representations that result from the compression and recursive binding of perceptual, lexical, and motor representations, effectively integrating traditional connectionist and symbolic approaches. We present a computational model using semantic pointers that replicates experimental data from categorization studies involving each prior paradigm. We argue that a framework involving semantic pointers can provide a unified account of conceptual phenomena, and we compare our framework to existing alternatives in accounting for the scope, content, recursive combination, and neural implementation of concepts.     

Exploring Enactive Realism

Abstract

The paper considers the success of enactive realism about perception; the theory that perceivers gain direct access to the mind-independent physical world through their exercise of sensorimotor skills and understanding. I argue that while it is plausible that the possession of some forms of knowledge, conceptual or practical, may enable perceptual contact with the environment, the role of sensorimotor mastery is not as pervasive as the enactive realist proposes. Non-veridical perception, furthermore, cannot be captured adequately by enactivist resources under a disjunctivist framework.     

Enactment of approach and avoidance behavior influences the scope of perceptual and conceptual attention

In this study, we tested the hypothesis, derived from the theorizing of Derryberry and Tucker (1994), that the mere enactment of approach or avoidance behavior, without concomitant pursuit of personal approach or avoidance goals, can independently moderate the scope (i.e., breadth or narrowness) of attention on both the perceptual and conceptual levels. Specifically, we predicted that enactment of approach behavior would broaden attentional scope, engendering a focus upon global perceptual structure and facilitating conceptual access to mental representations with lower a priori accessibility, whereas enactment of avoidance behavior would constrict attentional scope, engendering a focus upon local perceptual details and “choking off” conceptual access to mental representations with lower a priori accessibility. These hypotheses were borne out in three experiments, using two different manipulations of approach vs. avoidance actions.     

Nietzsche on the Nature of the Unconscious

Abstract

This paper argues that Nietzsche develops a novel and compelling account of the distinction between conscious and unconscious mental states: he argues that conscious mental states are those with conceptual content, whereas unconscious mental states are those with nonconceptual content. I show that Nietzsche’s puzzling claim that consciousness is ‘superficial’ and ‘falsifying’ can be given a straightforward explanation if we accept this understanding of the conscious/unconscious distinction. I originally defended this view in my ‘Nietzsche’s Theory of Mind: Consciousness and Conceptualization’ (2005, European Journal of Philosophy 13: 1–31); since then, the view has come under criticism on several fronts. Brian Leiter and others suggest that there is not enough textual evidence for the view. In addition, Leiter, Mattia Riccardi and Tsarina Doyle argue that, rather than aligning the conscious/unconscious distinction with the conceptual/nonconceptual distinction, Nietzsche endorses a higher-order thought model of consciousness. Riccardi also objects that Nietzsche must treat some unconscious mental states as conceptual. In this essay, I defend the interpretation in light of these objections. I provide new textual evidence for the interpretation, show that Nietzsche extracted aspects of the view from Schopenhauer’s work on consciousness, consider the possibility that Nietzsche endorses a higher-order thought theory, and respond to Riccardi’s objection.     

How to build a baby: On the development of an accessible representational system

The notion of a sensorimotor stage in infancy is called into question. First, some of the recent experimental literature on cognitive development in infancy is examined to determine the kinds of representational capacity that these data require. It is concluded that most of the recent work on perceptual development and the object concept in infancy is compatible with the notion of a sensorimotor stage but that other work showing imitation, motor recognition, the acquisition of manual signs, and recall of absent objects is not, requiring, instead, a conceptual form of representation. Such a system is apparent early in development. It is suggested that there is a viable alternative to Piaget's theory that conceptual representation consists of a transformation of sensorimotor schemas into a new, more advanced code. It is proposed that an accessible conceptual system develops simultaneously and in parallel with the sensorimotor system, with neither system being derivative from the other. It is further proposed that the mechanism by which infants encode information into an accessible system consists of a process of perceptual analysis.     

CONSCIOUS REFERENCE

The world shows up to perceptual consciousness in virtue of the deployment of distinct sensorimotor and also conceptual skills. The availability of the world to thought, is, in contrast, to be explained in connection with the different sorts of skills put to work in thought. I show that thought and experience are varieties of skilful access to the world. The aim of the paper is to present the outlines of a general theory of access.     

Linking somatic and symbolic representation in semantic memory: the dynamic multilevel reactivation framework

Biological plausibility is an essential constraint for any viable model of semantic memory. Yet, we have only the most rudimentary understanding of how the human brain conducts abstract symbolic transformations that underlie word and object meaning. Neuroscience has evolved a sophisticated arsenal of techniques for elucidating the architecture of conceptual representation. Nevertheless, theoretical convergence remains elusive. Here we describe several contrastive approaches to the organization of semantic knowledge, and in turn we offer our own perspective on two recurring questions in semantic memory research: (1) to what extent are conceptual representations mediated by sensorimotor knowledge (i.e., to what degree is semantic memory embodied)? (2) How might an embodied semantic system represent abstract concepts such as modularity, symbol, or proposition? To address these questions, we review the merits of sensorimotor (i.e., embodied) and amodal (i.e., disembodied) semantic theories and address the neurobiological constraints underlying each. We conclude that the shortcomings of both perspectives in their extreme forms necessitate a hybrid middle ground. We accordingly propose the Dynamic Multilevel Reactivation Framework—an integrative model predicated upon flexible interplay between sensorimotor and amodal symbolic representations mediated by multiple cortical hubs. We discuss applications of the dynamic multilevel reactivation framework to abstract and concrete concept representation and describe how a multidimensional conceptual topography based on emotion, sensation, and magnitude can successfully frame a semantic space containing meanings for both abstract and concrete words. The consideration of ‘abstract conceptual features’ does not diminish the role of logical and/or executive processing in activating, manipulating and using information stored in conceptual representations. Rather, it proposes that the materials upon which these processes operate necessarily combine pure sensorimotor information and higher-order cognitive dimensions involved in symbolic representation.     

The clinical utility of Piagetian-based scales of infant development

The clinical utility of assessment scales based on Jean Piaget's theory of infant development is described. A clinical process is presented which permits one to determine (a) whether a child is showing delayed or non-delayed sensorimotor performance, (b) whether a child is showing normal or atypical patterns of sensorimotor development, (c) the extent to which deviations in a child's patterns of development are present, (d) the exact nature of such deviations, if any, and (e) what types of interventions are most appropriate for enhancing a child's acquisition of sensorimotor competencies. Four examples of the application of the clinical process are presented.     

Husserl and the representational theory of mind

Husserl has finally begun to be recognized as the precursor of current interest in intentionality — the first to have a general theory of the role of mental representations in the philosophy of language and mind. As the first thinker to put directedness of mental representations at the center of his philosophy, he is also beginning to emerge as the father of current research in cognitive psychology and artificial intelligence.My thanks to David Woodruff Smith and Frank McGuinness for their invaluable help with the issues addressed in this paper.     

Neuroconstructivism

Neuroconstructivism is a theoretical framework focusing on the construction of representations in the developing brain. Cognitive development is explained as emerging from the experience-dependent development of neural structures supporting mental representations. Neural development occurs in the context of multiple interacting constraints acting on different levels, from the individual cell to the external environment of the developing child. Cognitive development can thus be understood as a trajectory originating from the constraints on the underlying neural structures. This perspective offers an integrated view of normal and abnormal development as well as of development and adult processing, and it stands apart from traditional cognitive approaches in taking seriously the constraints on cognition inherent to the substrate that delivers it.
