Cognitive penetration of perception, broadly understood, is the influence that the cognitive system has on a perceptual system. The paper shows a form of cognitive penetration in the visual system which I call ‘architectural’. Architectural cognitive penetration is the process whereby the behaviour or the structure of the perceptual system is influenced by the cognitive system, which consequently may have an impact on the content of the perceptual experience. I scrutinize a study in perceptual learning that provides empirical evidence that (...) cognitive influences in the visual system produce neural reorganization in the primary visual cortex. The type of cognitive penetration can be synchronic and diachronic. (shrink)

Abstract:When I throw a ball at you, do you see it as catch‐able? Do we perceive objects as edible, climbable or Q‐able in general? One could argue that it is just a manner of speaking to say so: we do not reallyseean object as edible, we only infer on the basis of its other properties that it is. I argue that whether or not an object is edible or climbable is indeed represented perceptually: weseeobjects as edible, and do not just (...) believe that they are. My argument proceeds in two steps. First, I argue that in order to perform an action Q with respect to an object, we need to represent this object as Q‐able and, second, I argue that we represent objects as having these propertiesperceptually.

This volume examines the limitations of mathematical logic and proposes a new approach to logic intended to overcome them. To this end, the book compares mathematical logic with earlier views of logic, both in the ancient and in the modern age, including those of Plato, Aristotle, Bacon, Descartes, Leibniz, and Kant. From the comparison it is apparent that a basic limitation of mathematical logic is that it narrows down the scope of logic confining it to the study of deduction, without (...) providing tools for discovering anything new. As a result, mathematical logic has had little impact on scientific practice. Therefore, this volume proposes a view of logic according to which logic is intended, first of all, to provide rules of discovery, that is, non-deductive rules for finding hypotheses to solve problems. This is essential if logic is to play any relevant role in mathematics, science and even philosophy. To comply with this view of logic, this volume formulates several rules of discovery, such as induction, analogy, generalization, specialization, metaphor, metonymy, definition, and diagrams. A logic based on such rules is basically a logic of discovery, and involves a new view of the relation of logic to evolution, language, reason, method and knowledge, particularly mathematical knowledge. It also involves a new view of the relation of philosophy to knowledge. This book puts forward such new views, trying to open again many doors that the founding fathers of mathematical logic had closed historically. (shrink)

Tracing the leading role of emotions in the evolution of the mind, a philosopher and a psychologist pair up to reveal how thought and culture owe less to our faculty for reason than to our capacity to feel. Many accounts of the human mind concentrate on the brain’s computational power. Yet, in evolutionary terms, rational cognition emerged only the day before yesterday. For nearly 200 million years before humans developed a capacity to reason, the emotional centers of the brain were (...) hard at work. If we want to properly understand the evolution of the mind, we must explore this more primal capability that we share with other animals: the power to feel. Emotions saturate every thought and perception with the weight of feelings. The Emotional Mind reveals that many of the distinctive behaviors and social structures of our species are best discerned through the lens of emotions. Even the roots of so much that makes us uniquely human—art, mythology, religion—can be traced to feelings of caring, longing, fear, loneliness, awe, rage, lust, playfulness, and more. From prehistoric cave art to the songs of Hank Williams, Stephen T. Asma and Rami Gabriel explore how the evolution of the emotional mind stimulated our species’ cultural expression in all its rich variety. Bringing together insights and data from philosophy, biology, anthropology, neuroscience, and psychology, The Emotional Mind offers a new paradigm for understanding what it is that makes us so unique.

What is the role of the environment, and of the information it provides, in cognition? More specifically, may there be a role for certain artefacts to play in this context? These are questions that motivate "4E" theories of cognition (as being embodied, embedded, extended, enactive). In his take on that family of views, Hajo Greif first defends and refines a concept of information as primarily natural, environmentally embedded in character, which had been eclipsed by information-processing views of cognition. He continues (...) with an inquiry into the cognitive bearing of some artefacts that are sometimes referred to as 'intelligent environments'. Without necessarily having much to do with Artificial Intelligence, such artefacts may ultimately modify our informational environments. -/- With respect to human cognition, the most notable effect of digital computers is not that they might be able, or become able, to think but that they alter the way we perceive, think and act.

A comprehensive introduction to the Language of Though Hypothesis (LOTH) accessible to general audiences. LOTH is an empirical thesis about thought and thinking. For their explication, it postulates a physically realized system of representations that have a combinatorial syntax (and semantics) such that operations on representations are causally sensitive only to the syntactic properties of representations. According to LOTH, thought is, roughly, the tokening of a representation that has a syntactic (constituent) structure with an appropriate semantics. Thinking thus consists in (...) syntactic operations defined over representations. Most of the arguments for LOTH derive their strength from their ability to explain certain empirical phenomena like productivity, systematicity of thought and thinking. (shrink)

It is generally accepted that there is something special about reasoning by using mental images. The question of how it is special, however, has never been satisfactorily spelled out, despite more than thirty years of research in the post-behaviorist tradition. This article considers some of the general motivation for the assumption that entertaining mental images involves inspecting a picture-like object. It sets out a distinction between phenomena attributable to the nature of mind to what is called the cognitive architecture, and (...) ones that are attributable to tacit knowledge used to simulate what would happen in a visual situation. With this distinction in mind, the paper then considers in detail the widely held assumption that in some important sense images are spatially displayed or are depictive, and that examining images uses the same mechanisms that are deployed in visual perception. I argue that the assumption of the spatial or depictive nature of images is only explanatory if taken literally, as a claim about how images are physically instantiated in the brain, and that the literal view fails for a number of empirical reasons – for example, because of the cognitive penetrability of the phenomena cited in its favor. Similarly, while it is arguably the case that imagery and vision involve some of the same mechanisms, this tells us very little about the nature of mental imagery and does not support claims about the pictorial nature of mental images. Finally, I consider whether recent neuroscience evidence clarifies the debate over the nature of mental images. I claim that when such questions as whether images are depictive or spatial are formulated more clearly, the evidence does not provide support for the picture-theory over a symbol-structure theory of mental imagery. Even if all the empirical claims were true, they do not warrant the conclusion that many people have drawn from them: that mental images are depictive or are displayed in some (possibly cortical) space. Such a conclusion is incompatible with what is known about how images function in thought. We are then left with the provisional counterintuitive conclusion that the available evidence does not support rejection of what I call the “null hypothesis”; namely, that reasoning with mental images involves the same form of representation and the same processes as that of reasoning in general, except that the content or subject matter of thoughts experienced as images includes information about how things would look.

Post-Gibson attempts to set out a definition of affordance generally agree that this notion can be understood as a property of the environment with salience for an organism’s behavior. According to this view, some scholars advocate the idea that affordances are dispositional properties of physical objects that, given suitable circumstances, necessarily actualize related actions. This paper aims at assessing this statement in light of a theory of affordance perception. After years of discontinuity between strands of empirical and theoretical research, the (...) time is ripe for addressing the question of whether the dispositional interpretation of affordance is in accordance with some recent evidence from cognitive science and neuroscience. Following this line, I clarify that there are some cases of affordance-related effects that neither require the actualization of an action, nor the presence of an action-related property bearer in the environment, and that the identification of affordance with physical properties provides only a partial explanation of the wide range of affordance-related effects. Accordingly, I argue in favor of a more general account of affordance perception based on the ability to directly detect perceptual patterns in the environment. (shrink)

A number of studies in the apparent motion literature were examined using the cognitive penetrability criterion to determine the extent to which beliefs affect the perception of apparent motion. It was found that the interaction between the perceptual processes mediating apparent motion and higher order processes appears to be limited. In addition, perceptual and inferential beliefs appear to have different effects on perceived motion optimality and direction. Our findings suggest that the system underlying apparent motion perception has more than one (...) stage and is informationally encapsulated from cognitive factors. (shrink)

We offer an ecological (Gibsonian) alternative to cognitive (im)penetrability. Whereas Pylyshyn explains cognitive (im)penetrability by focusing solely on computations carried out by the nervous system, according to the ecological approach the perceiver as a knowing agent influences the entire animal-environmental system: in the determination of what constitutes the environment (affordances), what constitutes information, what information is detected and, thus, what is perceived.

Interface theory is the hypothesis that inferential, representational theories of perception entail that fitness, not truth, dictates the evolution of perceptual systems. They show, with simulations, that “veridical” perceptual mappings (ones that preserve at least some of the structure of the world) are routinely out-competed by “non-veridical” interfaces (ones that make no attempt to preserve that structure). They therefore take particular aim at the direct perception, ecological approach to perception and work to show that such a system, even if technically (...) an option, would never be selected for by evolution. This paper defends the ecological approach from this novel, existential attack by showing that the ecological hypothesis is so different in kind to the inferential, representational view of perception that it simply falls outside the scope of interface theory’s critiques; ecological psychology remains a viable scientific endeavor. This analysis will show that, far from being a radical new approach to perception, interface theory is simply a clear and elegant formalization of mainstream representational psychology, and any implications interface theory may have belong solely to that branch of science.

In his 1995 book Colour vision (New York: Routledge), Evan Thompson proposes a new approach to the ontology of color according to which it is tied to the ecological dispositions-affordances described by J.J. Gibson and his followers. Thompson claims that a relational account of color is necessary in order to avoid the problems that go along with the dispute between subjectivists and objectivists about color, but he claims that the received view of perception does not allow a satisfactory relational account (...) of color. Hence to avoid the problems of the subjectivist/objectivist dispute one must abandon the received view of perception. I describe an account which is similar to Thompson's, but which invokes instead the physical dispositional properties described by the received view. All of the distinguishing characteristics that Thompson claims separate his ecological dispositions from physical dispositions are in fact found in the physical dispositions appealed to by my proposed theory. Because my proposed theory is similar to subjectivism, Thompson's departure from the received view is not as radical as he claims. In a final section I describe the a posteriori manner in which a substantive departure from the received view must be carried out by describing an example of ecological experimentation. (shrink)

Vera & Simon (1993a) have argued that the theories and methods known as situated action or situativity theory are compatible with the assumptions and methodology of the physical symbol systems hypothesis and do not require a new approach to the study of cognition. When the central criterion of computational universality is added to the loose definition of a symbol system which Vera and Simon provide, it becomes apparent that there are important incompatibilities between the two approaches such that situativity theory (...) cannot be subsumed within the symbol systems approach. Symbol systems and situativity theoretic approaches are, and should be seen to be, competing approaches to the study of cognition. (shrink)

According to ecological psychology, animals perceive not just the qualities of things in their environment, but their affordances: in James Gibson’s words, ’what things furnish, for good or ill’. I propose a metaphysics for affordances that fits into a contemporary anti-Humean metaphysics of powers or potentialities. The goal is to connect two debates, one in the philosophy of perception and one in metaphysics, that stand to gain much from each other.

The ecological realist concept of information as environmental specification is discussed. It is argued that affordances in ecological realism could, in principle, rest on a notion of partial specification of environmental circumstances. For this aim, a notion of Gestalt quality as a hierarchical structure of affordances would have to be adopted. It is claimed that such an account could provide a promising way to deal with problems of intentionality in perception and action, awareness and problem solving.

This study addresses the dynamical nature of a “representation‐hungry” cognitive task involving an imagined action. In our experiment, participants were handed rods that systematically increased or decreased in length on subsequent trials. Participants were asked to judge whether or not they thought they could reach for a distant object with the hand‐held rod. The results are in agreement with a dynamical model, extended from Tuller, Case, Ding, and Kelso (1994). The dynamical effects observed in this study suggest that predictive judgments (...) regarding the possibility or impossibility of a certain action can be understood in terms of dynamically evolving basins of attraction instead of as depending on representational structures.

This paper explores the conscious visual experience of seeing race. In everyday occurrences, racialized seeing involves the capacity for a subject to simply “see” that someone she encounters belongs to a racial category. I bridge research in analytic philosophy of perception and accounts from phenomenologists and critical race theorists on the lived experience of racialized seeing. I contend that we should not trust our visual experiences of racialized seeing because they provide, at best, incomplete information on a target’s racial identity. (...) I make a case for a version of perceptual learning that I think both captures actual experiences of racialized seeing and is empirically plausible. Finally, I follow work of critical race theorists in suggesting that normative constraints surrounding racial identity and privilege are built into our experiences of racialized seeing. Both types of racialized seeing are subject to social norms and practices and, thus, aid in perpetuating racial hierarchies. (shrink)

This paper explores the concept of “gendered seeing”: the capacity to visually perceive another person's gender and the role that one's own gender plays in that perception. Assuming that gendered properties are actually perceptible, my goal is to provide some support from the philosophy of perception on how gendered visual experiences are possible. I begin by exploring the ways in which sociologists and psychologists study how we perceive one's sex and the implications of these studies for the sex/gender distinction. I (...) then discuss feminist philosopher Linda Alcoff's concept of “interpretative horizons,” which highlights the role that one's social and political identities play in how we understand the world around us. I also discuss Elizabeth Grosz's notion of double sensation. I then apply some work in the philosophy of perception on perceptual learning and the cognitive penetration of perception to gendered seeing. My hypothesis is that we can explain how one's interpretative horizons are acquired through some notion of perceptual learning. I conclude by suggesting some of the epistemic and ethical implications of gendered seeing. (shrink)

: We provide empirical examples to conceptually clarify some items on Firestone & Scholl’s (F&S’s) checklist, and to explain perceptual effects from an attentional and memory perspective. We also note that action and embodied cognition studies seem to be most susceptible to misattributing attentional and memory effects as perceptual, and identify four characteristics unique to action studies and possibly responsible for misattributions.

For my part, my only hope is, that I may contribute a little to the advancement of knowledge, by giving in some particulars a different turn to the speculations of philosophers, and pointing out to them more distinctly those subjects, where alone they can expect assurance and conviction.

In this paper we secure the explanatory value of affordances by treating them as relational properties and as inherently linked to unintentional movements and possible intentional actions. We distinguish between Basic affordances, which are related to unintentional movements, and Complex affordances, which are subjective and executively controlled by individuals. The linkage between affordances and motor intentions allows for accounting for the infinite number of affordances that any given object potentially has. Appealing to objective systematic contingencies that provide the actor with (...) information about the effects of her actions, allows for accounting for perception of affordances and for securing their explanatory value.

The purpose of the paper is twofold. It first aims at clarifying and developing an important tension within enactivism concerning the relations between intentionality and content, once representationalism has been abandoned. In which sense(s) do enactivists (still) say that intentionality is contentful and not contentful? Secondly, it puts this tension in perspective with two paradigmatic ways of defining the relations between intentional states and their objects: Husserl’s theory of intentionality in the Logical Investigations, and Charles Sanders Peirce’s triadic semiotics.

Noam Chomsky and other linguists and psychologists have suggested that human linguistic behavior is somehow governed by a mental representation of a transformational grammar. Challenges to this controversial claim have often been met by invoking an explicitly computational perspective: It makes perfect sense to suppose that a grammar could be represented in the memory of a computational device and that this grammar could govern the device's use of a language. This paper urges, however, that the claim that humans are such (...) a device is unsupported and that it seems unlikely that linguists and psychologists really want to claim any such thing. Evidence for the linguists' original claim is drawn from three main sources: the explanation of language comprehension and other linguistic abilities; evidence for formal properties of the rules of the grammar; and the explanation of language acquisition. It is argued in this paper that none of these sources provides support for the view that the grammar governs language processing in something like the way a program governs the operation of a programmed machine. The computational approach, on the contrary, suggests ways in which linguistic abilities can be explained without the attribution of any explicit representation of rules governing linguistic behavior.

According to direct perception approaches we directly see others’ emotions, and by seeing emotions we immediately ascribe them to others. Direct perception is explicitly presented as an alternative account of mindreading, but it also contains an implicit thesis about the extent of the reach of perception. In this paper emotion perception is defended: siding with the direct perception approach I claim that we can simply see emotions and not just low level features of the facial and bodily displays, but contra (...) the direct perception approach I argue that seeing emotions is not sufficient for recognizing emotions as mental states in order to ascribe them to others.
