In the generative tradition, the language faculty has been shrinking—perhaps to include only the mechanism of recursion. This paper argues that even this view of the language faculty is too expansive. We first argue that a language faculty is difficult to reconcile with evolutionary considerations. We then focus on recursion as a detailed case study, arguing that our ability to process recursive structure does not rely on recursion as a property of the grammar, but instead emerge gradually by piggybacking on (...) domain-general sequence learning abilities. Evidence from genetics, comparative work on non-human primates, and cognitive neuroscience suggests that humans have evolved complex sequence learning skills, which were subsequently pressed into service to accommodate language. Constraints on sequence learning therefore have played an important role in shaping the cultural evolution of linguistic structure, including our limited abilities for processing recursive structure. Finally, we re-evaluate some of the key considerations that have often been taken to require the postulation of a language faculty. (shrink)

Naturalistic theories of disease appeal to concepts of biological function, and use the notion of dysfunction as the basis of their definitions. Debates in the philosophy of biology demonstrate how attributing functions in organisms and establishing the function-dysfunction distinction is by no means straightforward. This problematization of functional ascription has undermined naturalistic theories and led some authors to abandon the concept of dysfunction, favoring instead definitions based in normative criteria or phenomenological approaches. Although this work has enhanced our understanding of (...) disease and illness, we need not necessarily abandon naturalistic concepts of function and dysfunction in the disease debate. This article attempts to move towards a new naturalistic theory of disease that overcomes the limitations of previous definitions and offers advantages in the clinical setting. Our approach involves a re-evaluation of concepts of biological function employed by naturalistic theories. Drawing on recent insights from the philosophy of biology, we develop a contextual and evaluative account of function that is better suited to clinical medicine and remains consistent with contemporary naturalism. We also show how an updated naturalistic view shares important affinities with normativist and phenomenological positions, suggesting a possibility for consilience in the disease debate. (shrink)

The calibration solution to the stability of the world despite eye movements depends, according to Bridgeman et al., upon a combination of three factors which presumably all need to operate to achieve the goal of stability. Although the authors admit (sect. 4.3, para. 5) that the relative contributions of retinal and extraretinal factors will depend on the particular viewing situation, Figure 5 (sect. 4.3) makes it clear in its representation that the role of perceptual factors is relatively minor compared to (...) extraretinal ones. It is with this representation that this commentary wishes to take issue, believing that it occurs as a result of some assumptions about terminology that may be ambiguous, as well as some misconceptions about the circumstances in which there is a need for stability.

“Terms that have histories cannot be defined.” – Nietzsche“[T]he reality to which we were attending seemed to resist our thinking it.” – Cora Diamond[1] Much has been learned in recent decades about the behaviour and abilities of many species of non-human animals. Increasingly many who reflect on the abilities of languageless animals are uncomfortable with a once prevalent dichotomy of either assigning these abilities to the realm of mere mechanism or granting such creatures full rationality and more or less the (...) entire range of abilities that involves. This has lead to no little reflection and debate regarding how to proceed in studying animal “cognition,” and about what counts as adequately or accurately explaining animal behaviour. I cautiously hope herein to contribute to the clarity of what is already a discussion too rich and complex to do any justice to here. Little of what I say will be original, but the particular way of approaching the issues herein may shed some light on why certain issues have endured. (shrink)

We provide a taxonomy of the two most important debates in the philosophy of the cognitive and neural sciences. The first debate is over methodological individualism: is the object of the cognitive and neural sciences the brain, the whole animal, or the animal--environment system? The second is over explanatory style: should explanation in cognitive and neural science be reductionist-mechanistic, inter-level mechanistic, or dynamical? After setting out the debates, we discuss the ways in which they are interconnected. Finally, we make some (...) recommendations that we hope will help philosophers interested in the cognitive and neural sciences to avoid dead ends. (shrink)

Preston & de Waal are understandably cautious in applying their model to autism. They emphasise multiple cognitive impairments in autism, including prefrontal-executive, cerebellar-attention, and amygdala-emotion recognition deficits. Further empirical examination of imitation ability in autism may reveal deficits in the neural and cognitive basis of perception-action mapping that have a specific relation to the empathic deficit.

In Section 5 of his interesting article, Goldman suggests that the consideration of imaginary cases can be valuable in the analysis of our psychological concepts. In particular, he argues that we can imagine a system that is isomorphic to us under any functional description, but which lacks qualitative mental states, such as pains and color sensations. Whether or not such a being is empirically possible, it certainly seems to be logically possible, or conceptually coherent. Goldman argues from this possibility to (...) the conclusion that our concepts of qualitative mental states cannot be analyzed entirely in functional terms. (shrink)

According to Hubert Dreyfus’s famous claim that expertise is fundamentally “mindless,” experts in any domain perform most effectively when their activity is automatic and unmediated by concepts or cognitive processes like attention and memory. While several scholars have recently challenged the plausibility of Dreyfus’s “mindless” account of expertise for explaining a wide range of expert activities, there has been little consideration of the one form of expertise which might be most amenable to Dreyfus’s account – namely, perceptual expertise. Indeed, Dreyfus’s (...) account of expert coping is ultimately an account of perceptual expertise, in that an expert’s intuitive situational responses are thought to rely on a sophisticated repertoire of perceptual skills. In this paper, I examine the feedforward model of sensory processing that Dreyfus uses to illustrate the perceptual underpinnings of expert action, and consider its resonance with psychological research that characterizes perceptual expertise as being automatic, holistic, pre-attentive, and non-cognitive in nature. However, citing competing empirical research, I argue instead that Dreyfus’s model of perceptual expertise cannot adequately explain the integral roles of attention, memory, and conceptual knowledge in expert object recognition. I conclude that the Dreyfusian model of perceptual expertise fails – the perceptual repertoire of skills that grounds expert object recognition is not operative in isolation from the expert’s conceptual repertoire.

I defend a moderate (neither extremely conservative nor extremely liberal) view about the contents of perception. I develop an account of perceptual kinds as perceptual similarity classes, which are convex regions in similarity space. Different perceivers will enjoy different perceptual kinds. I argue that for any property P, a perceptual state of O can represent something as P only if P is coextensive with some perceptual kind for O. 'Dog' and 'chair' will be perceptual kinds for most normal people, 'blackpool (...) warbler' for the expert birdwatcher but not for the rest of us, 'dangerous', 'familiar', or 'meaning that the cat is on the mat' for none of us.

Descriptive metaphysics investigates our naïve ontology as this is articulated in the content of our perception or of our pre-reflective thought about the world. But is access to such content reliable? Sceptics about the standard modes of access (introspection, or language-driven intuitions) may think that investigations in descriptive metaphysics can be aided by the controlled findings of cognitive science. Cognitive scientists have studied a promising range of representational advantages, that is, ways in which cognition favours one type of entity over (...) another. The notion of representational advantage is investigated and some scepticism is expressed as to its appropriateness for use in descriptive metaphysics. (shrink)

In this paper, we provide an overview of research highlighting the relation between cultural processes, social norms, and food choices, discussing the implication of these findings for the promotion of more sustainable lifestyles. Our aim is to outline how environmental psychological research on urban affordances, through the specific concepts of restorative environments and walkability, could complement these findings to better understand human health, wellbeing and quality of life. We highlight how social norms and cultural processes are linked to food choices, (...) and we discuss the possible health-related outcomes of cultural differences in food practices, their relation to acculturation and globalization processes. We also discuss the concepts of restorative environments and walkability as positive urban affordances, and their relation to human well being, and the possibile link with cultural process and sustainable lifestyles. Finally, we outline issues for future research and areas for policy making and interventions on the links between cultural processes, healthy and sustainable food consumption and urban affordances, for the pursuit of public health, wellbeing and environmental sustainability.

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. (shrink)

Jeffery et al. extensively and thoroughly describe how different species navigate through a three-dimensional environment. Undeniably, the world offers numerous three-dimensional opportunities. However, we argue that for most navigation tasks a two-dimensional representation is nevertheless sufficient, as physical conditions and limitations such as gravity, thermoclines, or layers of earth encountered in a specific situation provide the very elevation data the navigating individual needs.

Many edusemiotic writers have begun to closely align edusemitoics to biosemiotics; the basic logic being that, if the life process can be defined through the criterion of semiotic engagement, so can the learning process :373–387, 2006). Thus, the ecological concept of umwelt has come to be a central area of investigation for edusemiotics; allowing theorists to address learning and living concurrently, from the perspective of meaning and significance. To address the conceptual and experiential foundations of the edusemiotic perspective, this paper (...) will focus its attention on the basic semiosic processes that sustain the learner’s primary modelling system or umwelt—the world of meaning and sensory engagement that the organism is immersed in. This focus enables us to identify and explore four basic principles that an ecologically concerned edusemiotic perspective can be said to rest upon; the Iconicity Hypothesis, the Principle of Suprasubjective Relation, the Natural Learning Flow Principle, and the Continuity Principle. The identification and elaboration of these basic philosophical orientations will help establish the importance and relevance of the edusemiotic perspective for educational philosophy and theory in general. This task requires the methodological framework of Sebeok and Danesi’s Modelling Systems Theory, which; provides a biosemiotically grounded approach to understanding the diversity of modelling phenomena across all species, and; contextualizes the specific focus of this study within the broader forms of learning and knowing encompassed by a semiotic theory of learning. Hopefully such attention to the foundational doctrina of this new perspective will encourage more educational research to take what Semetsky has called the edusemiotic turn. (shrink)

Rejecting information-processing-based theory permits the merging of a top-down analysis of visual search tasks with a bottom-up analysis of brain structure and function. This reveals the true nature of the functional visual field and its precise role in the conduct of visual search tasks. The merits of such analyses over the traditional methods of the authors are described.

I argue that the debate about the reason-giving character of perception, and, derivatively, the contemporary debate about the nature of the conceptual content of perception, is best viewed as a confrontation with refined versions of the following three independently plausible, yet mutually inconsistent, propositions: Perceptual apprehension Some perceptions provide reasons directly Exclusivity Only beliefs provide reasons directly Bifurcation No perception is a belief I begin with an evaluation and refinement of each proposition so as to crystallize the source of the (...) difficulties that dominate our thinking about the reason-giving character of perception. I argue that the contemporary literature is broadly split between those denying Bifurcation and those denying Perceptual apprehension. Though Exclusivity, too, has been target to criticism, its grip on our thinking has all too often been underestimated. As a result, a proper denial or modification of Exclusivity is yet wanting. Overcoming Exclusivity involves a considerable challenge that has not been adequately acknowledged or met—to develop a substantive account of nonconceptual apprehension. Getting a clearer understanding of the nature, the source, and possible resolution of this challenge is the primary aim of this paper. (shrink)

To explain social learning without invoking the cognitively complex concept of imitation, many learning mechanisms have been proposed. Borrowing an idea used routinely in cognitive psychology, we argue that most of these alternatives can be subsumed under a single process, priming, in which input increases the activation of stored internal representations. Imitation itself has generally been seen as a This has diverted much research towards the all-or-none question of whether an animal can imitate, with disappointingly inconclusive results. In the great (...) apes, however, voluntary, learned behaviour is organized hierarchically. This means that imitation can occur at various levels, of which we single out two clearly distinct ones: the a rather detailed and linear specification of sequential acts, and the a broader description of subroutine structure and the hierarchical layout of a behavioural Program level imitation is a high-level, constructive mechanism, adapted for the efficient learning of complex skills and thus not evident in the simple manipulations used to test for imitation in the laboratory. As examples, we describe the food-preparation techniques of wild mountain gorillas and the imitative behaviour of orangutans undergoing to the wild. Representing and manipulating relations between objects seems to be one basic building block in their hierarchical programs. There is evidence that great apes suffer from a stricter capacity limit than humans in the hierarchical depth of planning. We re-interpret some chimpanzee behaviour previously described as and suggest that all great apes may be able to imitate at the program level. Action level imitation is seldom observed in great ape skill learning, and may have a largely social role, even in humans. (shrink)
