The issue of the cognitive impenetrability or penetrability of perception lay dormant for a long period of time. Though philosophers reacted to the relativism implied by the work of Hanson, Kuhn, and Feyerabend, they concentrated their efforts in dealing with the danger of the incommensurability of theories. They tried to show by philosophical and detailed historical analysis that scientists within different paradigms do communicate with each other and put their respective theories to the empirical test. Curiously enough the same philosophers did not seek to examine the very foundation of the relativistic trend, namely the thesis that perception is cognitively penetrable and theory-laden. In the last decade there has been a keen interest in studying the cognition/perception boundary. However, the discussion focused mainly on the grounding of conceptual content on perception and on the embodiment of cognition. The repercussions of these issues for the problem of the cognitive effects on perception were largely ignored. The chapters in this book address directly the issue of the cognitive penetrability of perception. The volume consists of eleven chapters, each one addressing the issue from a different perspective. Eight of the chapters were written by philosophers and cognitive scientists, and three by psychologists and neuropsychologists. These differences notwithstanding, the chapters share many common themes. The role of attention in perception, the contribution of action to perception, the relation between perception and scientific data, the examination of the content of perception and its nature and the detailed examination of the ways background knowledge affects perception, are among these themes. Most chapters combine philosophical analysis with psychological and/or neuropsychological evidence, which shows that there is consensus as to the kind of approaches that are currently deemed necessary for an adequate examination of the problem.

This book is about the interweaving between cognitive penetrability and the epistemic role of the two stages of perception, namely early and late vision, in justifying perceptual beliefs. It examines the impact of the epistemic role of perception in defining cognitive penetrability and the relation between the epistemic role of perceptual stages and the kinds (direct or indirect) of cognitive effects on perceptual processing. The book presents the argument that early vision is cognitively impenetrable because neither is it affected directly by cognition, nor does cognition affect its epistemic role. It also argues that late vision, even though it is cognitively penetrated and, thus, affected by concepts, is still a perceptual state that does not involve any discursive inferences and does not belong to the space of reasons. Finally, an account is given as to how cognitive states with symbolic content could affect perceptual states with iconic, analog content, during late vision.

This monograph presents a clear account of when and how attentional processes can shape perceptual experience. This argument is based on the prediction-error minimization model of the mind. The author believes that the topic of attention should take a more central role in the debate about the influence of cognition on perception. Inside, he shows how this can be possible. The hypothesis that cognition may shape perceptual experience has been traditionally labeled as the cognitive penetrability of perceptual experience. Cognitive penetrability is relevant for several debates in philosophy and cognitive science. It tackles the possibility of gathering genuine knowledge on the basis of perceptual information about the world delivered by sensory channels. The problem, the author notes, is that if our previously acquired belief can shape current perceptual experiences, such experiences cannot serve as an adequate source of justification in retaining those beliefs or even forming new ones. He argues that cognitive penetration may sometimes happen through attentional processes, but that its occurrence need not undermine perceptual justification. The book provides an overview of the cognitive penetrability debate. The author discusses evidence that supports the occurrence of this phenomenon. Overall, this investigation offers readers a philosophical discussion of attention based on the biased-competition theory. It argues that attention is a property of mental representations that emerges from a metacognitive competition process.

Attention has often been likened to spotlights and filters—devices that illuminate or screen out some inputs in favor of others. This largely passive conception of attention has been gradually replaced by a more dynamic and far-reaching process. We know that attentional processes augment neural processing at all levels, and in some cases, augmenting processing within the sense organs themselves. For example, cueing object features (e.g., instructing a subject to look at a screen for a red object) modulates prestimulus activity in the visual cortex. Far from being limited to space or basic features, such attention cueing can function in surprisingly flexible and complex ways: people can be cued to attend to various objects, properties, and semantic categories and such attention appears to directly involve perceptual mechanisms. Studies of spatial attention cues presented before stimulus presentation show early modulation of perceptual processing. This phenomenon refers to the enhancement of the baseline activity of neurons at all levels in the visual cortex that are tuned to the cued location, which is called attentional modulation of spontaneous activity. The spontaneous firing rates of neurons are increased when attention is shifted toward the location of an upcoming stimulus before its presentation. Evidence also suggests that through pre-cueing of object features, feature-based attention modulates prestimulus activity in the visual cortex. The effects of pre-stimulus feature attention act either as a preparatory activity to enhance the stimulus-evoked potentials within feature sensitive areas, or they act so as to modulate stimulus-locked transients. Both effects of pre-cueing reflect a change in background neural activity. They are called anticipatory effects established prior to the presentation of the stimulus. Thus, they do not modulate processing during stimulus viewing but bias the process before it starts via the increase in the base line firing rates; they rig-up perceptual processing without affecting it on-line. Moreover, recent work on perceptual processing emphasizes the role of brain as a predictive tool. To perceive is to use what you know to explain away the sensory signal across multiple spatial and temporal scales. Perception aims to enable perceivers to interact with their environment successfully. Success relies on inferring or predicting correctly (or nearly so) the nature of the source of the incoming signal from the signal itself, an inference that may well be Bayesian. Current research sheds light on the role of attention in inferring the identities of the distal objects. Attention within late vision contributes to testing hypotheses concerning the putative distal causes of the sensory data encoded in the lower neuronal assemblies in the visual processing hierarchy. This testing assumes the form of matching predictions, made on the basis of an hypothesis, about the sensory information that the lower levels should encode assuming that the hypothesis is correct, with the current, actual sensory information encoded at the lower levels. To this aim, attention enhances the activity of neurons in the cortical regions that encode the stimuli that most likely contain information relevant to the testing of the hypothesis. In this Research Topic we aim to answer two related questions: First, what are the differences between this sort of pre-cueing effects and top-down cognitive influences on perception, and, in general, how do such attentional cuing effects relate to the broader literature on top-down influences on perception? Second, given that attention appears to change perceptual processing and that a form of attention, namely, cognitively-driven (or endogenous, or sustained) attention is a cognitive process, does attentional modulation through pre-cueing constitute cognitive penetrability of perception? Addressing these two questions will shed light on the theoretical underpinnings of cognitive penetrability and the nature of perceptual processing.

An argument that there are perceptual mechanisms that retrieve information in cognitively and conceptually unmediated ways and that this sheds light on various philosophical issues. In Cognition and Perception, Athanassios Raftopoulos discusses the cognitive penetrability of perception and claims that there is a part of visual processes (which he calls “perception”) that results in representational states with nonconceptual content; that is, a part that retrieves information from visual scenes in conceptually unmediated, “bottom-up,” theory-neutral ways. Raftopoulos applies this insight to problems in philosophy of science, philosophy of mind, and epistemology, and examines how we access the external world through our perception as well as what we can know of that world. To show that there is a theory-neutral part of existence, Raftopoulos turns to cognitive science and argues that there is substantial scientific evidence. He then claims that perception induces representational states with nonconceptual content and examines the nature of the nonconceptual content. The nonconceptual information retrieved, he argues, does not allow the identification or recognition of an object but only its individuation as a discrete persistent object with certain spatiotemporal properties and other features. Object individuation, however, suffices to determine the referents of perceptual demonstratives. Raftopoulos defends his account in the context of current discussions on the issue of the theory-ladenness of perception (namely the Fodor-Churchland debate), and then discusses the repercussions of his thesis for problems in the philosophy of science. Finally, Raftopoulos claims that there is a minimal form of realism that is defensible. This minimal realism holds that objects, their spatiotemporal properties, and such features as shape, orientation, and motion are real, mind-independent properties in the world.

There is an important division in the human mind between perception and reasoning. We reason from information that we have already, but perception is a means of taking in new information. Susanna Siegel argues that these two aspects of the mind become deeply intertwined when beliefs, fears, desires, or prejudice influence what we perceive.

Experts from wine tasters to radiologists to bird watchers have all undergone perceptual learning-long-term changes in perception that result from practice or experience. Philosophers have been discussing such cases for centuries, from the 14th-century Indian philosopher Vedanta Desika to the 18th-century Scottish philosopher Thomas Reid, and into contemporary times. This book uses recent evidence from psychology and neuroscience to show that perceptual learning is genuinely perceptual, rather than post-perceptual. It also offers a taxonomy for classifying cases in the philosophical literature. In some cases, perceptual learning involves changes in how one attends; in other cases, it involves a learned ability to differentiate two properties, or to perceive two properties as unified. Connolly uses this taxonomy to rethink several domains of perception in terms of perceptual learning, including multisensory perception, color perception, and speech perception. As a whole, the book offers a theory of the function of perceptual learning. Perceptual learning embeds into our quick perceptual systems what would be a slower task were it to be done in a controlled, cognitive manner. A novice wine taster drinking a Cabernet Sauvignon might have to think about its features first and then infer the type of wine, while an expert can identify it immediately. This learned ability to immediately identify the wine enables the expert to think about other things like the vineyard or the vintage of the wine. More generally, perceptual learning serves to free up cognitive resources for other tasks. This book offers a comprehensive empirically-informed account, and explores the nature, scope, and theoretical implications of perceptual learning.

In this volume the philosophy of perception and observation is discussed by leading philosophers with implications in the philosophy of mind, in epistemology, and in philosophy of science. In the last years the philosophy of perception underwent substantial changes and new views appeared: the intentionality of perception has been contested by relational theories of perception (direct realism), a richer view of perceptual content has emerged, new theories of intentionality have been defended against naturalistic theories of representation (e. g. phenomenal intentionality). These theoretical changes reflect also new insights coming from psychological theories of perception. These changes have substantial consequences for the epistemic role of perception and for its role in scientific observation. In the present volume, leading philosophers of perception discuss these new views and show their implications in the philosophy of mind, in epistemology and in philosophy of science. A special focus is laid on Franz Brentano and Ludwig Wittgenstein. A reference volume for all scholars and students of the history, psychology and philosophy of perception, and cognitive science.
