Cognitive Development and Acquisition of Language.

On standard readings of Grice, Gricean communication requires (a) possession of a concept of belief, (b) the ability to make complex inferences about others’ goal-directed behaviour, and (c) the ability to entertain fourth order meta-representations. To the extent that these abilities are pre-requisites of Gricean communication they are inconsistent with the view that Gricean communication could play a role in their development. In this paper, I argue that a class of ‘minimally Gricean acts’ satisfy the intentional structure described by (...) Grice, but require none of abilities (a)-(c). As a result, Gricean communicative abilities may indeed contribute to the development of (a)-(c) – in particular, by enabling language development. This conclusion has important implications for our theorising about cognitive development. (shrink)

Why do children learn language more easily than adults do? This puzzle has fascinated cognitive and language scientists for decades. In the present letter, we approach the language learning puzzle from a cognitive perspective that is inspired by evidence from the perceptual and motor learning literature. Neuroscientific studies show that two memory systems in the brain are involved in human learning: an early implicit procedural memory system and a late-developing cognitive or declarative memory system. We argue that (...) higher cognitive development constrains implicit statistical learning processes that are essential for learning patterns and regularities in languages, that is, the adult cognitive architecture has a cost. This is supported by experimental evidence showing that acquisition of implicit linguistic knowledge is enhanced under cognitive depletion in adults. More research is needed to test the cognitive cost hypothesis as it could partly solve the language learning puzzle. (shrink)

The progress in the machine consciousness research field has to be assessed in terms of the features demonstrated by the new models and implementations currently being designed. In this paper, we focus on the functional aspects of consciousness and propose the application of a revision of ConsScale — a biologically inspired scale for measuring cognitive development in artificial agents — in order to assess the cognitive capabilities of machine consciousness implementations. We argue that the progress in the (...) implementation of consciousness in artificial agents can be assessed by looking at how key cognitive abilities associated to consciousness are integrated within artificial systems. Specifically, we characterize ConsScale as a partially ordered set and propose a particular dependency hierarchy for cognitive skills. Associated to that hierarchy a graphical representation of the cognitive profile of an artificial agent is presented as a helpful analytic tool. The proposed evaluation schema is discussed and applied to a number of significant machine consciousness models and implementations. Finally, the possibility of generating qualia and phenomenological states in machines is discussed in the context of the proposed analysis. (shrink)

In Concepts, Kinds, and Cognitive Development, Frank C. Keil provides a coherent account of how concepts and word meanings develop in children, adding to our understanding of the representational nature of concepts and word meanings at all ages. Keil argues that it is impossible to adequately understand the nature of conceptual representation without also considering the issue of learning. Weaving together issues in cognitive development, philosophy, and cognitive psychology, he reconciles numerous theories, backed by empirical (...) evidence from nominal kinds studies, natural-kinds studies, and studies of fundamental categorical distinctions. He shows that all this evidence, when put together, leads to a better understanding of semantic and conceptual development. The book opens with an analysis of the problems of modeling qualitative changes in conceptual development, investigating how concepts of natural kinds, nominal kinds, and artifacts evolve. The studies on nominal kinds document a powerful and unambiguous developmental pattern indicating a shift from a reliance on global tabulations of characteristic features to what appears to be a small set of defining ones. The studies on natural kinds document an analogous shift toward a core theory instead of simple definition. Both sets of studies are strongly supported by cross cultural data. While these patterns seem to suggest that the young child organizes concepts according to characteristic features, Keil argues that there is a framework of conceptual categories and causal beliefs that enables even very young children to understand kinds at a deeper, theoretically guided, level. This account suggests a new way of understanding qualitative change and carries strong implications for how concepts are represented at any point in development. A Bradford Book. (shrink)

_Cognitive Developments in Economics_ proposes an interdisciplinary approach to the study of human problem solving, choice, decision-making and change, to explain economic transactions, and the nature and evolution of organisations and institutions. The book contributes to a large spectrum of economic fields such as consumer theory, economics of the firm, economics of innovation, evolutionary economics and experimental economics.

This paper discusses how to use cognitive developmental psychology to create a business ethics course that has philosophical integrity. It begins with the pedagogical problem to be overcome when students are not philosophy majors. To provide a context for the practical recommendations, Kohlberg's cognitive developmental theory is summarized and then the relationship between Kohlberg's theory, normative philosophy, and teaching is analyzed. The conclusion recommends strategies that should help overcome some of the vexing pedagogical problems mentioned in the first (...) section. In particular, the approach is designed to teach an appreciation for the practical necessity of philosophy in a pluralistic society. (shrink)

How do minds emerge from developing brains? According to the representational features of cortex are built from the dynamic interaction between neural growth mechanisms and environmentally derived neural activity. Contrary to popular selectionist models that emphasize regressive mechanisms, the neurobiological evidence suggests that this growth is a progressive increase in the representational properties of cortex. The interaction between the environment and neural growth results in a flexible type of learning: minimizes the need for prespecification in accordance with recent neurobiological evidence (...) that the developing cerebral cortex is largely free of domain-specific structure. Instead, the representational properties of cortex are built by the nature of the problem domain confronting it. This uniquely powerful and general learning strategy undermines the central assumption of classical learnability theory, that the learning properties of a system can be deduced from a fixed computational architecture. Neural constructivism suggests that the evolutionary emergence of neocortex in mammals is a progression toward more flexible representational structures, in contrast to the popular view of cortical evolution as an increase in innate, specialized circuits. Human cortical postnatal development is also more extensive and protracted than generally supposed, suggesting that cortex has evolved so as to maximize the capacity of environmental structure to shape its structure and function through constructive learning.

This paper rejects the notion of moral education in adulthood as merely remedial, i.e. as providing a second chance to learn that which should have been learned in school, or as merely compensatory, i.e. as making up for the waning of our cognitive abilities which (stereotypically) occurs with age. Rather, it advocates a conception of lifelong moral education which presupposes that there are social and cognitive features of maturity which have the potential to generate some worthwhile learning which (...) can therefore only be acquired in adulthood. First the theoretical issues associated with this presupposition will be outlined and the notions of dialectical/relativistic and eclectic/synthesising forms of thinking, as adult stages of thinking, will be explored in the context of moral development and education. Secondly, reference will be made to some relatively recent research undertaken (at the Department of Continuing Education, University of Warwick) into the impact of liberal adult education certificated courses on the mature student's sense of identity. In‐depth interviews revealed that the students themselves perceive their learning in terms of adult cognitive development. Moreover, the courses were found to have had a significant impact on their self‐understanding. In so far as the development is an aspect of moral education, these research findings have some significance for lifelong moral education. (shrink)

Greater emphasis on the bidirectionality of peer interaction and cognitive development would complement the suggested framework of children’s contribution to cultural evolution. We outline different aspects/forms of socio-cognitive development to illustrate their roles in cultural processes: social learning, theory of mind, and pretend play. We encourage the consideration of peer cultures in urban settings and the role siblings play.

This Element describes the main theories that guide contemporary research in cognitive development along with research discoveries in several important cognitive abilities: attention, language, social cognition, memory, metacognition and executive function, and problem solving and reasoning. Biological and social contributions are considered side-by-side, and cultural contributions are highlighted. As children participate in social interactions and learn to use cultural symbols and tools to organize and support their thinking, the behaviors and understandings of the social community and the (...) culture more broadly become an integral part of children's thoughts and actions. Culture, the natural ecological setting or habitat of human beings, plays a significant role by providing support and direction for cognitive development. Without the capacity to learn socially, human cognition would be markedly different from what it is today. (shrink)

There is clearly some area of thematic overlap between the subject matter of Edmund Husserl's genetic phenomenology and studies of cognitive development. I aim in this paper to clarify the extent of this overlap. This will, I hope, serve as an indicator about whether genetic phenomenology might be able to shed some light on actual cognitive-development phenomena. To begin with, I differentiate two strands within Husserl's genetic phenomenology, an idealized and a concrete approach. After providing a (...) schematic outline of the former I argue that its application to actual, empirical cases of cognitive development faces serious challenges. I then set out the concrete approach, in two stages. First, I explain the importance of bodily experience on the concrete approach and note some affinities it has with the work of Piaget and embodied approaches to cognitive development. Second, I introduce the notion of affect as the engine of the developmental process on the concrete approach, an idea that, moreover, helps clarify how the concrete approach overcomes the problems facing the idealized approach. Finally, I propose that Vygotsky's notion of the 'zone of proximal development' can serve as a bridge between Husserl's concrete approach and contemporary scaffolded and extended accounts of cognitive development.

I discuss three key differences between Pettit's philosophical genealogy and other influential works of cognitive development. They are: (i) concern with the temporal distribution of changes from a starting state A to the envisaged end state B, (ii) constraints on the specification of A and (iii) claims about the likelihood of the transition from A to B. I argue that legitimate concerns can be raised about Pettit's treatment of (ii) and (iii). Nonetheless, When minds converse proposes a series (...) of original, compelling and empirically testable hypotheses about the role of conversation in cognitive development. (shrink)

In Section 1, I introduce three views that explain human cognitive development from different standpoints: Marcus’s neo-nativism, standard neuroconstructivism, and neo-neuroconstructivism. In Section 2, I assess Marcus’s attempt to reconcile nativism with developmental flexibility. In Section 3, I argue that in structurally reconfiguring nativism, Marcus ends up transforming it into an unrecognizable form, and I claim that his view could be accommodated within the more general framework provided by standard neuroconstructivism. In Section 4, I focus on recent empirical (...) findings in neuropsychology and cultural/social neuroscience, and propose a friendly revision to standard neuroconstructivism, thus developing the neo-neuroconstructivist view. I conclude the article in Section 5 by analysing the implications of the results discussed in Section 4 for both neo-nativism and standard neuroconstructivism. 1 Introduction2 Marcus’s Neo-nativism3 Is Marcus’s Neo-nativism Really a Form of Nativism?4 Neo-neuroconstructivism and Dynamic Enskillment5 Conclusion.

Thelen et al.'s account of cognition as the dynamic interaction of processes of perceiving, reaching, and remembering within a movement planning field is a useful articulation of the Piagetian concept of sensorimotor cognition. The claim that the same kind of analysis applies to all kinds of cognition at all ages, however, is questioned in light of the distinction between sensorimotor and symbolic cognition.

Attempting to balance the needs and interests of minors with the obligation to protect them from their own potentially harmful decisions poses an ethical challenge for the physician. This problem is further exacerbated when the context is not medical treatment but organ donation. That is, medical treatment scenarios generally involve decisions likely to result in objective improvements to the minor's health status. Consent to organ donation, however, raises several vexing problems. First, how should the provider measure both the cognitive (...) ability and competence to consent of the minor to ensure that the minor comprehends the risks and benefits of donation and that no coercion is involved? Second, given that improvement of one's health is an unlikely scenario, is there a way to measure subjective determinations of satisfaction and altruism enjoyed by a minor following organ donation? If so, should the physician regard these values in a manner analogous to physical improvement? Finally, are parents the appropriate decisionmakers for their children when a sibling-to-sibling donation occurs? Is it possible for parents to always act in the best interests of both children in this event? (shrink)

Depression is vastly heterogeneous in its symptoms, neuroimaging data, and treatment responses. As such, describing how it develops at the network level has been notoriously difficult. In an attempt to overcome this issue, a theoretical “negative prediction mechanism” is proposed. Here, eight key brain regions are connected in a transient, state-dependent, core network of pathological communication that could facilitate the development of depressive cognition. In the context of predictive processing, it is suggested that this mechanism is activated as a (...) response to negative/adverse stimuli in the external and/or internal environment that exceed a vulnerable individual’s capacity for cognitive appraisal. Specifically, repeated activation across this network is proposed to update an individual’s brain so that it increasingly predicts and reinforces negative experiences over time—pushing an individual at-risk for or suffering from depression deeper into mental illness. Within this, the negative prediction mechanism is poised to explain various aspects of prognostic outcome, describing how depression might ebb and flow over multiple timescales in a dynamically changing, complex environment.

In this study, we investigated the relationship between mothers' psychological lexicon and children's cognitive and socio-emotive development as assessed through conceptual and semantic understanding tasks, in addition to the traditional tasks of theory of mind. Currently, there is considerable evidence to suggest that the frequency of mothers' mental state words used in mother-child picture-book reading is linked with children's theory of mind skills. Furthermore, mothers' use of cognitive terms is more strongly related to children's theory of mind (...) performances than the mothers' references to other mental states, such as desires or emotions (Rollo and Buttiglieri, 2009 ). Current literature has established that early maternal input is related to later child mental state understanding; however it has not yet clarified which maternal terms are most useful for the socio-emotional and cognitive development of the child, and which aspect of the cognitive development benefits from the mother-child interaction. The present study addresses this issue and focuses on the relationship between mothers' mental state talk and children's behavior in conceptual and semantic tasks, and in a theory of mind task. In this study fifty pairs consisting of mothers and their 3 to 6-year-old children participated in two sessions: (1) The mothers read a picture book to their children. To assess the maternal psychological lexicon, their narrative was codified according to the categories of mental state references used in literature: perceptual, emotional, volitional, cognitive, moral, and communicative. (2) After a few days, the conceptual and semantic skills of the children (tasks of contextualization and classification, memory, and definition of words) and their psychological lexicon were assessed. The results suggest close links between the frequency and variety of mothers' mental state words and some semantic and conceptual skills of children. (shrink)

The contributions to this collection, written in honor of Jacques Mehler, a founder of the field of psycholinguistics, assess the progress of cognitive science.

This chapter advocates a view that is a substantive middle ground between the extreme versions of nativism and empiricism — a view dubbed ‘rational constructivism’. This is a view that commits us to some innate (or acquired) constraints and a set of powerful learning and inference mechanisms that may be critical for development. The mechanisms of statistical inference are used as a means to bridge the gap between discussions of innate knowledge and discussions of learning and conceptual change. In (...) particular, the general framework of Bayesian inference is adopted and some recent research providing empirical evidence for the psychological reality of these inference mechanisms are presented.

Once the notion of a precursive relationship between developmental stages is fully articulated in terms of the distinction between ‘role’ and ‘realiser’ states, it turns out that the ‘Theory of Mind’ literature operates with a notion of precursive relationships described at too high a level of abstraction to explain actual mechanisms of development. Furthermore, the tendency within that literature to explain precursive relationships in terms of role states with isomorphic linguistic/computational structures is misleading. Developmental relationships are more likely to (...) exist between states which play a similar normative role in the agents’s psychology than between states which can be described as sharing a similar computational architecture.

The premise of this article is that cognitive development involves both conceptual and semiotic achievements. From this perspective, the authors emphasize the distinctness of the semiotic issues and develop a differentiated appreciation of the semiotic aspects of cognition, particularly in the field of elementary mathematical cognition. The authors provide semiotic analyses of the differences between counting, adding, and multiplying and of the conventional place-value system. The authors introduce the concept of the field of reference of a sign, the (...) differentiation of the field into foreground and background, and the dynamics within the field of reference. Finally, the authors relate these ideas to the dynamics between two dimensions of semiotic relations: the sign-referent dimension and the sign-sign dimension. (shrink)

Thelen et al. not only offer an important new theoretical account of the Stage 4 object permanence error but provide the foundation of a new theory of cognitive development that is grounded in action. The success of dynamic field theory as a more general account of cognitive functioning, however, will depend on the degree to which it can model more generative capacities that are not limited to simple choice situations. Imitation and problem solving are suggested as two (...) capacities that might be productively modeled within their approach. (shrink)

Millikan's theory of substance concepts has advantages for psychological theories, including those in cognitive development. However, the disadvantage is that it cannot be generalized even to some of the most common concepts that children acquire in the early years of life. For a general theory we must get beyond substances.

Psychologists have long debated the underlying cause of infants' perseverative reaching. Thelen et al. explain the error in terms of general processes that make goal-directed actions to remembered locations. The context- and experience-dependent nature of their model implies that there is no single cause of the A-not-B error, and, more generally, no core essence to cognitive development.
