Studies in the psychology of visual expertise have tended to focus on a limited set of expert domains, such as radiology and athletics. Conclusions drawn from these data indicate that experts use parafoveal vision to process images holistically. In this study, we examined a novel, as-of-yet-unstudied class of visual experts—architects—expecting similar results. However, the results indicate that architects, though visual experts, may not employ the holistic processing strategy observed in their previously studied counterparts. Participants (n = 48, 24 architects, (...) 24 naïve) were asked to find targets in chest radiographs and perspective images. All images were presented in both gaze-contingent and normal viewing conditions. Consistent with a holistic processing model, we expected two results: (1) architects would display a greater difference in saccadic amplitude between the gaze- contingent and normal conditions, and (2) architects would spend less time per search than an undergraduate control group. We found that the architects were more accurate in the perspectival task, but they took more time and displayed a lower difference in saccadic amplitude than the controls. Our research indicates a disjunctive conclusion. Either architects are simply different kinds of visual experts than those previously studied, or we have generated a task that employs visual expertise without holistic processing. Our data suggest a healthy skepticism for across-the-board inferences collected from a single domain of expertise to the nature of visual expertise generally. More work is needed to determine whether holism is a feature of all visual expertise. (shrink)

This is a reply to the critical commentaries of Zed Adams, Zoe Drayson, Chris Mole, and Aleksandra Mroczko-Wąsowicz. The unifying theme across all four commentaries is the question: just how radical are the ideas contained in, and implied by, Thinking and Perceiving? Does the abandonment of the modularity of mind, and an embrace of the malleability of mind, have wide reaching consequences for empirical studies of sensory perception, for cognitive architecture, for the metaphysics of mind and the (...) epistemology of perception? And which of those consequences are welcomed, and which of those are problematic? These general questions anchor in (at least) the following topics: learning and the role of cognition, object recognition, perceptual expertise, early versus late vision, perception and truth, virtue epistemology, and computational architectures of mind. This reply attempts to address the overarching question from this variety of angles taken in the four commentaries. (shrink)

Expertise is a cognitive achievement that clearly involves experience and learning, and often requires explicit, time-consuming training specific to the relevant domain. It is also intuitive that this kind of achievement is, in a rich sense, genuinely perceptual. Many experts—be they radiologists, bird watchers, or fingerprint examiners—are better perceivers in the domain(s) of their expertise. The goal of this paper is to motivate three related claims, by substantial appeal to recent empirical research on perceptual expertise: Perceptual (...) expertise is genuinely perceptual and genuinely cognitive, and this phenomenon reveals how we can become epistemically better perceivers. These claims are defended against sceptical opponents that deny significant top-down or cognitive effects on perception, and opponents who maintain that any such effects on perception are epistemically pernicious.

This article reviews how behavioral methods, event-related potentials, and functional magnetic resonance imaging are used to understand the acquisition of perceptual expertise in both adult and developmental populations. The purpose of this study is to provide an overview of the research focused on understanding the role and nature of experience in both the acquisition of perceptual expertise and the development of expert face processing. Behavioral tasks designed to assess perceptual expertise in adults include: perceptual discrimination and (...) matching tasks and the categorization and recognition memory tasks. Training studies are used to mimic the natural acquisition of face and non-face perceptual expertise. Using these various methods and techniques, studies of perceptual expertise prove useful to the understanding of specialization of perceptual skills and categorization abilities and expands our understanding of the function and plasticity of the visual system.

Does the scope of beliefs that people can form on the basis of perception remain fixed, or can it be amplified with learning? The answer to this question is important for our understanding of why and when we ought to trust experts, and also for assessing the plausibility of epistemic foundationalism. The empirical study of perceptual expertise suggests that experts can indeed enrich their perceptual experiences through learning. Yet this does not settle the epistemic status of (...) their beliefs. One might hold that the background knowledge of experts is the cause of their enriched perceptual experience – what is known as cognitive permeation – and so their subsequent beliefs are only mediately justified because they are epistemically dependent on this background knowledge. I argue against this view. Perceptual expertise is not the result of cognitive permeation but is rather the result of perceptual learning, and perceptual learning does not involve cognition in a way that entails cognitive permeation. Perceptual expertise thus provides a means of widening the scope of the immediately justified beliefs that experts can form. (shrink)

Perceptual expertise refers to learning that is specific to a domain, that transfers to new items within the trained domain, and that leads to automatic processing in the sense that expertise effects can be measured across a variety of tasks. It can be argued that most of us possess some degree of perceptual expertise in a least one, if not several domains, thereby giving the study of perceptual expertise broad application. Some object categories may in fact be (...) objects of perceptual expertise to the majority of people: Faces appear to be one such example. Thus, the use of face stimuli, or the comparison of face and object perception, can be a powerful way to ask whether a given process is influenced by perceptual expertise. Here, we emphasize one characteristic way that face processing appears to differ from nonface processing: that is, the degree to which they recruit a “holistic” rather than a “featural” perceptual strategy. This review brings evidence that expertise influences perceptual processing together with recent findings that the capacity of visual short-term memory is greater in perceptual experts and explores the relationship between the two.

The problem of the cognitive penetrability of perception pertains to whether perceptual processing may be impacted by higher-order cognitive processes. It may be understood in a twofold sense: 1) whether what a perceptual system computes may be altered in a way that is semantically coherent to one’s cognitive states; 2) whether perceptual experience may be influenced by cognitive processes. It has been argued that the cognitive penetrability problem is not scientifically tractable since we have no direct (...) access to other persons’ subjective experiences and, therefore, we have to rely on their reports, which are mediated by higher-order processes (e.g., judgments). In this paper, I analyze the scope of methods harnessed in contemporary work on the penetrability of perception, focusing particularly on methods from experimental psychology and neuroscience. Among them, I indicate the most promising techniques and paradigms, as well as those that are inadequate to successfully tackling the problem. I also discuss experimental results which unequivocally suggest direct influences on perception which have not been addressed to date by supporters of the view that perception is impenetrable. I also describe the predictive processing theory of cognition, focusing on how it contributes to our understanding of cognitive penetrability, and discuss scientific results validating the theory. In conclusion, converging empirical evidence seems to suggest that perception is cognitively penetrable and we seem to be at the dawn of the ultimate solution of the problem. (shrink)

Dustin Stokes’s book contributes to one of the continuing debates in empirically informed philosophy of mind and cognitive sciences which concerns the relation between thought and perception. The book sheds new light on such questions as: whether vision is modular, informationally encapsulated, and thus cognitively impenetrable or rather the opposite – whether it is malleable and sensitive to further improvements by cognitive states. Stokes supports the latter by referring to empirical evidence on perceptual expertise. Proponents of the (...) modular and malleable architectures of the mind offer different explanations of the phenomena involved in perceptual expertise, viz. object identification and categorization. Interestingly, both views assume some kind of automaticity of the recognitional capacities for identifying and categorizing objects. In this article, I examine the influence of perceptual expertise on object recognition and how the seeming automaticity of object recognition may be approached from the modularist and antimodularist (malleabilist) perspectives.

Perception is our key to the world. It plays at least three different roles in our lives. It justifies beliefs and provides us with knowledge of our environment. It brings about conscious mental states. It converts informational input, such as light and sound waves, into representations of invariant features in our environment. Corresponding to these three roles, there are at least three fundamental questions that have motivated the study of perception. How does perception justify beliefs and yield (...) knowledge of our environment? How does perception bring about conscious mental states? How does a perceptual system accomplish the feat of converting varying informational input into mental representations of invariant features in our environment? -/- This book presents a unified account of the phenomenological and epistemological role of perception that is informed by empirical research. So it develops an account of perception that provides an answer to the first two questions, while being sensitive to scientific accounts that address the third question. The key idea is that perception is constituted by employing perceptual capacities - for example the capacity to discriminate instances of red from instances of blue. Perceptual content, consciousness, and evidence are each analyzed in terms of this basic property of perception. Employing perceptual capacities constitutes phenomenal character as well as perceptual content. The primacy of employing perceptual capacities in perception over their derivative employment in hallucination and illusion grounds the epistemic force of perceptual experience. In this way, the book provides a unified account of perceptual content, consciousness, and evidence. (shrink)

Through extensive training, experts acquire specialized knowledge and abilities. In this paper, I argue that experts also acquire specialized visual experiences. Specifically, I articulate and defend the account that experts enjoy visual experiences that represent gestalt properties through perceptual learning. I survey an array of empirical studies on face perception and perceptual expertise that support this account. I also look at studies on perceptual adaptation that some might argue present a problem for my (...) account. I show how the data are subject to an interpretation that is friendly to it. Last, I address two theoretical objections to the claim that visual experiences represent gestalt properties. (shrink)

The chapter argues from an ethology-inspired internalist perspective that ‘colour’ is not a homogeneous and autonomous attribute, but rather plays different roles in different conceptual forms underlying perception. It discusses empirical and theoretical evidence that indicates that core assumptions underlying orthodox conceptions are grossly inadequate. The assumptions pertain to the idea that colour is a kind of autonomous and unitary attribute. It is regarded as unitary or homogeneous by assuming that its core properties do not depend on the (...) type of ‘perceptual object’ to which it pertains and that‘colour per se’ constitutes a natural attribute in the functional architecture of the perceptual system. It is regarded as autonomous by assuming that it can be studied in isolation of other perceptual attributes. More generally, the chapter argues on the bases of corresponding empirical and theoretical evidence that perception cannot be understood as the ‘recovery’ of physical world structure from sensory structure by input-based computational processes. Rather, the sensory input serves as a kind of sign for biologically relevant aspects of the external world that activates biologically given conceptual forms with their internal parameters. Although the sensory input is a causally necessary requirement for the activation of conceptual forms, the perceptual computations triggered are under the control of an internal programme based on a set of conceptual forms.

Individuals' capacity to participate in leisure activities is contingent upon their ability to overcome obstacles. It is worthwhile to investigate how individuals perceive constraints on their leisure activities participation during the COVID-19 pandemic. This study demonstrates that the connotation of leisure constraints during pandemic includes personal health concerns, shock on economic revenue, reduced freedom of travel, and inconvenience associated with epidemic prevention. Reduced travel freedom is the most influential factor on participation intentions, followed by personal health concerns. Significant differences in (...) perceptions of constraints are observed between groups with different characteristics. (shrink)

In recent decades, scientists and philosophers have developed several naturalistic theories of consciousness, in which they try to work out some theoretical foundations for a satisfactory solution to the problem of voluntary acts, in particular the genesis of voluntary bodily movements. From the author’s point of view, depending on which concept of consciousness scientists rely on in their empirical studies of voluntary movements, volition can be understood either as a generative act or as a perceptual act. The (...) first part of the article shows that nowadays there are two competing philosophical and scientific models of volition: the generative model (dualistic and casualistic types) and the perceptual model (strong and weak types). The second part of the article deals with some experimental data from cognitive psychology and neuroscience related to the study of voluntary movements and concludes that they are in favor of the perceptive model of volition.

In some domains experts perform better than novices, and in other domains experts do not generally perform better than novices. According to empirical studies of expert performance, this is because the former but not the latter domains make available to training practitioners a direct form of learning feedback. Several philosophers resource this empirical literature to cast doubt on the quality of philosophical expertise. They claim that philosophy is like the dubious domains in that it does not make (...) available the good, direct kind of learning feedback, and thus there are empirical grounds for doubting the epistemic quality of philosophical expertise. I examine the empirical studies that are purportedly bad news for professional philosophers. On the basis of that examination, I provide three reasons why the empirical study of non-philosophical expertise does not undermine the status of philosophical expertise. First, the non-philosophical task-types from which the critics generalize are unrepresentative of relevant philosophical task-types. Second, empirical critiques of non-philosophical experts are often made relative to the performance of linear models—a comparison that is inapt in a philosophical context. Third, the critics fail to discuss findings from the empirical study of non-philosophical expertise that have more favorable implications for the epistemic status of philosophical expertise. In addition to discussing implications for philosophical expertise, this article makes progress in the philosophical analysis of the science of expertise and expert development. (shrink)

In this commentary on Dustin Stokes’ _Thinking and Perceiving_, I focus on his discussion of perceptual expertise. This discussion occurs in the context of his case against modularity assumptions that underlie much contemporary theorizing about perception. As I suggest, there is much to be gained from thinking about considerations about perceptual expertise in conjunction with considerations about imaginative skill. In particular, I offer three different lessons that we can learn by way of the joint consideration of these (...) two phenomena. (shrink)

When we see an object, we also represent those parts of it that are not visible. The question is how we represent them: this is the problem of amodal perception. I will consider three possible accounts: (a) we see them, (b) we have non-perceptual beliefs about them and (c) we have immediate perceptual access to them, and point out that all of these views face both empirical and conceptual objections. I suggest and defend a fourth account, (...) according to which we represent the occluded parts of perceived objects by means of mental imagery. This conclusion could be thought of as a (weak) version of the Strawsonian dictum, according to which “imagination is a necessary ingredient of perception itself”. (shrink)

This paper proposes an empirical hypothesis that in some cases of social interaction we have an immediate perceptual access to others' minds in the perception of their embodied intentionality. Our point of departure is the phenomenological insight that there is an experiential difference in the perception of embodied intentionality and the perception of non-intentionality. The other's embodied intentionality is perceptually given in a way that is different from the givenness of non-intentionality. We claim that the (...) phenomenological difference in the perception of embodied intentionality and non-intentionality translates into an account of how, in some cases of social cognition, we perceive mental properties in the perception of embodied intentionality. The hypothesis derives support from a host of recent empirical studies in social neuroscience which demonstrate the importance of embodied engagements in understanding other minds. These studies reveal that embodied intersubjective interaction often builds on our ability to understand other minds in an immediate perceptual way not adequately investigated by theory-theory (TT) and simulation theories (ST) of mind-reading. We argue that there is a genuine, nontrivial difference in the informational content of the perception of embodied intentionality and the perception of non-intentionality which leads to a further difference in the way information is processed in the case of perception of embodied intentionality as opposed to the perception of non-intentionality. The full significance of such difference is appreciated only within an account of perception which views perception and action as tightly coupled. Thus, we propose an "action-oriented account of social perception" to develop a neurophilosophical account of the perceptual knowledge of other minds. (shrink)

I present a novel argument against the epistemic conception of perception according to which perception either is a form of knowledge or puts the subject in a position to gain knowledge about what is perceived. ECP closes the gap between a perceptual experience that veridically presents a given state of affairs and an experience capable of yielding the knowledge that the state of affairs obtains. Against ECP, I describe a particular case of perceptual experience in which (...) the following triad of claims is true: The experience presents a given state of affairs ; The experience is veridical; The experience cannot yield the knowledge that the state of affairs obtains. This case involves an empirically well-studied phenomenon, namely perceptual hysteresis, which involves the maintenance of a perceptual experience with a relatively stable content over progressively degrading sensory stimulations.

Ethical concerns of Internet users continue to rise. Accordingly, several scholars have called for systematic empirical research to address these issues. This study examines the conceptualization and measurement of consumers' perceptions regarding the ethics of online retailers.

Results, from a convenience sample of 357 online shoppers, suggest that CPEOR can be operationalized as a second-order (...) construct composed of four dimensions: security, privacy, fulfillment, and non-deception. Our findings also indicate that consumers' general Internet expertise significantly improves CPEOR and CPEOR are strongly predictive of consumers' WOM.

Perceptual learning is an enduring change in the perceptual system – and our resulting perceptions – due to practice or repeated exposure to a perceptual stimulus. It is involved in the acquisition of perceptual expertise: the ability to make rapid and reliable high-level categorizations of objects unavailable to novices. Attentional weighting is one process by which perceptual learning occurs. Advancing our understanding of this process is of particular importance for understanding what is learned in (...) class='Hi'>perceptual learning. Attentional weighting seems to favour the hypothesis that what experts learn is simply to better direct their attention to elements of the stimulus relevant to making post-perceptual categorizations. Here I argue against this hypothesis. Attentional weighting is an integral component of the process that allows experts to come to represent high-level properties in perceptual experience. (shrink)

Background Genome scientists and Ethical, Legal, and Social Implications of genetics (ELSI) scholars commonly inhabit distinct research cultures – utilizing different research methods, asking different research questions, and valuing different types of knowledge. Collaborations between these two communities are frequently called for to enhance the ethical conduct of genomics research. Yet, little has been done to qualitatively compare genome scientists’ and ELSI scholars’ perspectives on collaborations with each other and the factors that may affect these collaborations.Methods 20 semi-structured interviews with (...) US-based genome scientists and ELSI scholars were conducted between June–September 2021. Interviews were analyzed using inductive thematic analysis.Results Genome scientists and ELSI scholars provided different understandings of the value and goals of their collaborations with each other. Genome scientists largely perceived ELSI expertise to be relevant for human subjects research; they described ELSI scholars as communicators who help the public and/or study participants better understand genomics research. In comparison, ELSI scholars viewed themselves as developing and implementing policies; they expressed frustration at how scientists can misunderstand their research methods or negatively perceive them. A combination of factors – both structural (e.g., criteria for promotion) and cultural (e.g., perceptions of what colleagues value and respect) – seemed to shape these diverging perspectives.Conclusion Academic institutions, funders, and researchers commonly call for collaborations between genome scientists and ELSI scholars, but under-consider how their different conceptual frameworks, research methods, goals, norms, and values, conjoin to affect such partnerships. Acknowledging, exploring, and addressing the complex interplay between these factors could help to more effectively facilitate collaborations between genome scientists and ELSI scholars. (shrink)

Background. Attending to goal-relevant information can leave us metaphorically ‘blind’ or ‘deaf’ to the next relevant information while searching among distracters. This temporal cost lasting for about a half a second on the human selective attention has been long explored using the attentional blink paradigm. Although there is evidence that certain visual stimuli relating to one’s area of expertise can be less susceptible to attentional blink effects, it remains unexplored whether the dynamics of temporal selective attention vary with expertise and (...) objects types in the auditory modality. Methods. Using the auditory version of the attentional blink paradigm, the present study investigates whether certain auditory objects relating to musical and perceptual expertise could have an impact on the transient costs of selective attention. In this study, expert cellists and novice participants were asked to first identify a target sound, and then to detect instrumental timbres of cello or organ, or human voice as a second target in a rapid auditory stream. Results. The results showed moderate evidence against the attentional blink effect for voices independent of participants’ musical expertise. Experts outperformed novices in their overall accuracy levels of target identification and detection, reflecting a clear benefit of musical expertise. Importanly, the musicianship advantage disappeared when the human voices served as the second target in the stream. Discussion. The results are discussed in terms of stimulus salience, the advantage of voice processing, as well as perceptual and musical expertise in relation to attention and working memory performances.

It is through touch that we are able to interact directly with the world; it is our primary conduit of both pleasure and pain. Touch may be our most immediate and powerful sense—“the first sense" because of the central role it plays in experience. In this book, Matthew Fulkerson proposes that human touch, despite its functional diversity, is a single, unified sensory modality. Fulkerson offers a philosophical account of touch, reflecting the interests, methods, and approach that define contemporary philosophy; but (...) his argument is informed throughout by the insights and constraints of empirical work on touch. Human touch is a multidimensional object of investigation, Fulkerson writes, best served by using a variety of methods and approaches. -/- To defend his view of the unity of touch, Fulkerson describes and argues for a novel, unifying role for exploratory action in touch. He goes on to fill in the details of this unified, exploratory form of perception, offering philosophical accounts of tool use and distal touch, the representational structure of tangible properties, the spatial content of touch, and the role of pleasure in tactual experience. -/- Fulkerson’s argument for the unique role played by exploratory action departs notably from traditional vision-centric philosophical approaches to perception, challenging the received view that action plays the same role in all sensory modalities. The robust philosophical account of touch he offers in The First Sense has significant implications for our general understanding of perception and perceptual experience. (shrink)

Auditory perception is traditionally conceived as the perception of sounds — a friend’s voice, a clap of thunder, a minor chord. However, daily life also seems to present us with experiences characterized by the absence of sound — a moment of silence, a gap between thunderclaps, the hush after a musical performance. In these cases, do we positively hear silence? Or do we just fail to hear, and merely judge or infer that it is silent? This longstanding question (...) remains controversial in both the philosophy and science of perception, with prominent theories holding that sounds are the only objects of auditory experience and thus that our encounter with silence is cognitive, not perceptual. However, this debate has largely remained theoretical, without a key empirical test. Here, we introduce a novel empirical approach, presenting experimental evidence that silence can be genuinely perceived (not just cognitively inferred). We ask whether silences can ‘substitute’ for sounds in event-based auditory illusions — empirical signatures of auditory event representation in which auditory events distort perceived duration. Seven experiments introduce three new ‘silence illusions’ — the one-silence-is-more illusion, silence-based warping, and the oddball-silence illusion — each adapted from a prominent perceptual illusion previously thought to arise only from sounds. Subjects were immersed in ambient noise interrupted by silences structurally identical to the sounds in the original illusions. In all cases, silences elicited temporal distortions perfectly analogous to the illusions produced by sounds. Our results suggest that silence is truly heard, not merely inferred, introducing a general approach for studying absence perception. (shrink)

This chapter has four parts. I distinguishes some types of perceptual skills and highlights their importance in everyday perception. II identifies a well-studied class of perceptual skills: cases of perceptual expertise. III discusses a less studied possible instance of perceptual skill: picture perception. Finally, IV outlines some important mechanisms underlying perceptual skills, with special emphasis on attention and mental imagery.

According to one important proposal, the difference between perception and cognition consists in the representational formats used in the two systems (Carey, 2009; Burge, 2010; Block, 2014). In particular, it is claimed that perceptual representations are iconic, or image-like, while cognitive representations are discursive, or language-like. Taking object perception as a test case, this paper argues on empirical grounds that it requires discursive label-like representations. These representations segment the perceptual field, continuously pick out objects despite (...) changes in their features, and abstractly represent high-level features, none of which appears possible for purely iconic representations.

Perception is one of the most pervasive and puzzling problems in philosophy, generating a great deal of attention and controversy in philosophy of mind, psychology and metaphysics. If perceptual illusion and hallucination are possible, how can perception be what it intuitively seems to be, a direct and immediate access to reality? How can perception be both internally dependent and externally directed? Perception is an outstanding introduction to this fundamental topic, covering both the perennial and recent (...) work on the problem. Adam Pautz examines four of the most important theories of perception: the sense datum view; the internal physical state view; the representational view; and naïve realism, assessing each in turn. He also discusses the relationship between perception and the physical world and the issue of whether reality is as it appears. Useful examples are included throughout the book to illustrate the puzzles of perception, including hallucinations, illusions, the laws of appearance, blindsight, and neuroscientific explanations of our experience of pain, smell and color. The book covers both traditional philosophical arguments and more recent empirical arguments deriving from research in psychophysics and neuroscience. The addition of chapter summaries, suggestions for further reading and a glossary of terms make Perception essential reading for anyone studying the topic in detail, as well as for students of philosophy of mind, philosophy of psychology and metaphysics.

The nature of perceptual and memory processes is examined in the light of suggested complementarity between introspective and empirical traditions. The introspective material analysed here is that found in the Buddhist Abhidhamma literature of the Pali canon on the stages of perception. Possible psychological and neurophysiological correspondences to these stages are proposed. The model of perception advanced here emphasizes two phases. The first involves sensory analysis and related memory readout. I postulate that this phase is completed (...) when coherence in oscillatory neuronal patterns indicates a ‘match’ between sensory input and memory readout. The second phase results in consciousness of the object, which comes about when a connection is effected between the representation of the input as generated in phase one and a representation of self . ‘I’ is itself generated in this second phase in relation to the memory readout of phase one, since this readout includes relevant prior formations of ‘I’. It is suggested that ‘I’ functions in the organization of memory and recall. (shrink)

We examine a number of investigations of perceptual economy or, more specifically, of minimum tendencies and minimum principles in the visual perception of form, depth, and motion. A minimum tendency is a psychophysical finding that perception tends toward simplicity, as measured in accordance with a specified metric. A minimum principle is a theoretical construct imputed to the visual system to explain minimum tendencies. After examining a number of studies of perceptual economy, we embark on a (...) systematic analysis of this notion. We examine the notion that simple perceptual representations must be defined within the "geometric constraints" provided by proximal stimulation. We then take up metrics of simplicity. Any study of perceptual economy must use a metric of simplicity; the choice of metric may be seen as a matter of convention, or it may have deep theoretical and empirical implications. We evaluate several answers to the question of why the visual system might favor economical representations. Finally, we examine several accounts of the process for achieving perceptual economy, concluding that those which favor massively parallel processing are the most plausible. (shrink)

Perceptual modalities have been traditionally considered the product of dedicated biological systems producing information for higher cognitive processing. Psychological and neuropsychological evidence is offered which undermines this point of view and an alternative account of modality from the enactive approach to understanding cognition is suggested. Under this view, a perceptual modality is a stable form of perception which is structured not just by the biological sensitivities of the agent, but by their goals and the set of skills (...) or expertise which they are deploying at a given time. Such a view suggests that there is no such thing as an experience that is purely visual, auditory, or otherwise modal and that our attempts to understand consciousness and the mind must be conducted within a framework that provides an account of embodied, goal-directed adaptive coping with the world.

In lieu of an abstract, here is a brief excerpt of the content:Time and History in Alois Riegl's Theory of PerceptionMichael GubserIn an early essay, the Austrian art historian Alois Riegl (1858–1905), a pioneer of the modern discipline of art history, linked the creation of the zodiac images in calendar art to the designation of constellations in the heavens.1 Ancient calendar artists observed the motion of stars across the night sky and attempted to map them into recognizable patterns representing specific (...) temporal periods. Their efforts inscribed the cyclical temporality of the heavens into the images of the ancient calendar. This inherent temporality came to characterize all art forms in Riegl's work; his choice of calendar art as his earliest research topic heralded a career-long interest in the connection between temporality and artistic form. Art objects, he believed, were temporal as well as spatial. Just as the light from constellations reflected a deep history, artworks illuminated the passage of time by visually re-presenting the perceptual world of past eras.Riegl's work has garnered attention in recent decades among art historians and non–art historians alike. This interest is due in part to the renewed concern for disciplinary origins that art history, like other fields, has experienced in the wake of poststructuralist critiques. Scholars outside of art history have taken note of his work because of its broad scope and relevance for the study of historiography and perception; Riegl's work provides models for linking the analysis of specific artworks with a history of perception, exploring the relationship between monuments and memory, and analyzing the nature of visual modernity. Interest in Riegl also stems from his acknowledged impact on such preeminent philosophers and historical theorists as Erwin Panofsky, Paul Feyerabend, Gilles Deleuze, Fèlix Guattari, and above all Walter [End Page 451] Benjamin.2 Figures as varied as Georg Lukács, Karl Mannheim, Walter Gropius, and Mikhail Bakhtin have cited his work favorably.3 Riegl is perhaps best known for his attempts to dismantle the hierarchy of high and low art, his attack on the preeminence of classical aesthetic ideals, and his effort to construct a universal history of style. The combination of these commitments led him to consider European and non-European craft genres that fell outside conventional definitions of art. In books such as Problems of Style, Late Roman Art Industry, and The Group Portraiture of Holland, Riegl examined the high arts, decorative arts, and manufactured artifacts alike, gleaning insights into the structure of an era's perception from close descriptive analyses of its artwork.4 In Problems of Style, Riegl traced the development of ancient vegetal decorative motifs toward their fulfillment in the naturalized tendrils and acanthus leaves of Greek ornament. A single, universal development encompassed seemingly distinct motivic forms, and creative innovation was driven by an inner formal logic. Similarly, Late Roman Art Industry, the [End Page 452] epoch-making work that Walter Benjamin described as a revolution in art historical method,5 traced the gradual development of space as an object of artistic concern in the late Roman Empire. In this volume, Riegl explored his controversial notion of the Kunstwollen, or artistic will, which asserted art's autonomy on the basis of a formal creative volition internal to artworks.6 Finally, The Group Portraiture of Holland documented the emergence and decline of a "typically Hollandish painting" emphasizing space and attention.7Riegl scholars have frequently attempted to situate his art history within a variety of philosophical traditions, an effort complicated by Riegl's limited citation of sources. Several scholars have linked Riegl's historical vision with the embattled tradition of Hegelian philosophy. Riegl's teleology; his stress on the unified, internal, and purposive development of art; his notion of art as mind overcoming material; and even his emphasis on the role of the viewer in art all have a distinctly Hegelian resonance. Wolfgang Kemp fits Riegl squarely within a late-nineteenth-century Hegelian revival,8 Michael Podro incorporates him within a Hegelian critical tradition of art history that spanned the nineteenth and early twentieth centuries,9 and Michael Ann Holly posits a clear trajectory, linking Kant and Hegel with Riegl and Panofsky.10Others, however, just as firmly reject this...

We investigate the role of perceptual similarity in visual metaphor comprehension process. In visual metaphors, perceptual features of the source and the target are objectively present as images. Moreover, to determine perceptual similarity, we use an image-based search system that computes similarity based on low-level perceptual features. We hypothesize that perceptual similarity at the level of color, shape, texture, orientation, and the like, between the source and the target image facilitates metaphorical comprehension and aids creative (...) interpretation. We present three experiments, two of which are eye-movement studies, to demonstrate that in the interpretation and generation of visual metaphors, perceptual similarity between the two images is recognized at a subconscious level, and facilitates the search for creative conceptual associations in terms of emergent features. We argue that the capacity to recognize perceptual similarity—considered to be a hallmark of creativity—plays a major role in the creative understanding of metaphors. (shrink)

Long tradition in philosophy and in empirical psychology has it that the perceptual recovery of enduring objective size and shape proceeds through initial spatial appearance experiences—like the sensed changing visual field size of a receding car, or the shifting shape appearance of a coin as it rotates in depth. The present paper carefully frames and then critically examines such proposals. It turns out that these are contingent, empirical matters, requiring close examination of relevant research in perception (...) science in order to decide. The paper concludes with extended discussions of the empirical study of the perception of slant, size, and shape. (shrink)

In the first year of life, infants' speech perception becomes attuned to the sounds of their native language. This process of early phonetic learning has traditionally been framed as phonetic category acquisition. However, recent studies have hypothesized that the attunement may instead reflect a perceptual space learning process that does not involve categories. In this article, we explore the idea of perceptual space learning by implementing five different perceptual space learning models and testing them on (...) three phonetic contrasts that have been tested in the infant speech perception literature. We reproduce and extend previous results showing that a perceptual space learning model that uses only distributional information about the acoustics of short time slices of speech can account for at least some crosslinguistic differences in infant perception. Moreover, we find that a second perceptual space learning model, which benefits from word‐level guidance. performs equally well in capturing crosslinguistic differences in infant speech perception. These results provide support for the general idea of perceptual space learning as a theory of early phonetic learning but suggest that more fine‐grained data are needed to distinguish between different formal accounts. Finally, we provide testable empirical predictions of the two most promising models and show that these are not identical, making it possible to independently evaluate each model in experiments with infants in future research.

Against recent claims that infants begin with a sense of themselves as distinct selves, I propose that the infant's initial sense of self is still indeterminate and ambiguous, and is only progressively consolidated, beginning with embodied perceptions of others. Drawing upon Merleau-Ponty's phenomenology of perception and Hegel's notion of mutual recognition, and with reference to empirical studies in developmental psychology, I argue that perceiving other persons is significantly different from perceiving inanimate things. Until sufficient motor capacities have (...) developed for exploring and perceptually disambiguating inanimate things, it is only in perceiving others who recognize her that the infant is able to realize herself as a self. As the physiological and behavioural evidence suggests, whereas inanimate things initially captivate and dispossess the young infant, other people return her to herself. This paper lends support to the ideas that humans are ontologically social beings, and that selfhood is socially conditioned rather than given with consciousness. (shrink)

Both corruption and subjective wellbeing are of concern to academics and governments. Although some evidence suggests that corruption deteriorates subjective wellbeing, the relationship between perception of official corruption and subjective wellbeing is still unknown. This study aims to examine the link between perceived official corruption and subjective wellbeing in the context of China and whether satisfaction with government performance has a mediating effect in the process. Based on data from China General Social Survey, a structural equation model was used (...) to test the hypotheses. The results of 3,033 Chinese respondents suggest that perception of official corruption is negatively related to subjective wellbeing, and satisfaction with government performance plays a mediating role in the relationship between perception of official corruption and subjective wellbeing.

This paper deals with the philosophical questions which gave rise to the traditional realist theories of universals. The main thesis is that these same questions may also be interpreted as scientific-empirical questions. The study of these problems has begun only very recently and the relevance of the results for the traditional problem of intensional entities has only been remarked by few workers aware of the philosophical problem. The approach adopted here is that of regarding man as a perceptual (...) system situated in an environment and showing certain capacities like perception of universals. The possible ways of access to these entities is discussed on the basis of some recent empirical findings related to perception. One conclusion is that in order to answer the basic philosophical question of how properties, particulars and propositions are perceived may be answered within the domains of science, accepting only the usual presuppositions used in it. Basically, such an approach sees the root of the problem in the great complexity of information processing involved in the actual perception of properties, particulars and propositions. (shrink)

The question of whether perception can be penetrated by cognition is in the limelight again. The reason this question keeps coming up is that there is so much at stake: Is it possible to have theory-neutral observation? Is it possible to study perception without recourse to expectations, context, and beliefs? What are the boundaries between perception, memory, and inference (and do they even exist)? Are findings from neuroscience that paint a picture of perception as an inherently (...) bidirectional and interactive process relevant for understanding the relationship between cognition and perception? We have assembled a group of philosophers and psychologists who have been considering the thesis of cognitive (im)penetrability in light of these questions (Abdel Rahman & Sommer, 2008; Goldstone, Landy, & Brunel, 2011; Lupyan, Thompson-Schill, & Swingley, 2010; Macpherson, 2012; Stokes, 2011). Rather than rehashing previous arguments which appear, in retrospect, to have been somewhat ill-posed (Pylyshyn, 1999), this symposium will present a thesis of cognitive (im)penetrability that is at once philosophically satisfying, empirically testable, and relevant to the questions that cognitive scientists find most interesting.

Merleau-Ponty’s phenomenology of perception comprises two main levels of analysis: the description of the general foundation upon which all human perception occurs and that of the lived, situated aspects of perception, as experienced by individuals. These ‘structural’ and ‘situated’ accounts of perception assume, respectively, the existence of a pre-personal body, which all human beings possess in principle, and of a historical body, which is the product of an individual’s ‘synchronization’ with the world. A comprehensive and faithful (...) description of human perceptual experience must contain, simultaneously, the general, structural, individual, and situational elements involved in perception. It has also to show the ways in which these elements impact each other, leading to distinct outcomes. I propose, here, a situated account of perception that fulfills these requisites while confirming Merleau-Ponty’s insights and descriptions empirically, through cases of perceptual skill and learning in a large industrial plant near the Amazon rainforest in Brazil.

Several leadership and ethics scholars suggest that the transformational leadership process is predicated on a divergent set of ethical values compared to transactional leadership. Theoretical accounts declare that deontological ethics should be associated with transformational leadership while transactional leadership is likely related to teleological ethics. However, very little empirical research supports these claims. Furthermore, despite calls for increasing attention as to how leaders influence their followers’ perceptions of the importance of ethics and corporate social responsibility (CSR) for organizational effectiveness, (...) no empirical study to date has assessed the comparative impact of transformational and transactional leadership styles on follower CSR attitudes. Data from 122 organizational leaders and 458 of their followers indicated that leader deontological ethical values (altruism, universal rights, Kantian principles, etc.) were strongly associated with follower ratings of transformational leadership, while leader teleological ethical values (utilitarianism) were related to follower ratings of transactional leadership. As predicted, only transformational leadership was associated with follower beliefs in the stakeholder view of CSR. Implications for the study and practice of ethical leadership, future research directions, and management education are discussed. (shrink)

BackgroundPatients who follow a specific religion may experience specific moral conflicts when interacting with the health care system. Health care providers’ awareness of and sensitivity to such issues can be beneficial to patients and increase the quality of care they receive. The aims of this study were to investigate which potential ethical issues were considered to be relevant to Muslim patients and to examine if these assessments varied between Muslim non-medical, Muslim medical, and non-Muslim medical students.MethodsAn online questionnaire with n (...) = 205 students from different universities in Zurich, Switzerland was conducted. The questionnaire contained a list of ethical issues of presumed relevance to Muslim patients, which had been compiled based on a literature search and an expert consultation.ResultsMuslim non-medical students considered 33% of the ethical issues as morally problematic to Muslim patients. In contrast, Muslim medical students regarded 19%, and non-Muslim medical studen... (shrink)

Cognitive and affective penetration of perception refers to the influence that higher mental states such as beliefs and emotions have on perceptual systems. Psychological and neuroscientific studies appear to show that these states modulate the visual system at the visuomotor, attentional, and late levels of processing. However, empirical evidence showing that similar consequences occur in early stages of visual processing seems to be scarce. In this paper, I argue that psychological evidence does not seem to be (...) either sufficient or necessary to argue in favour of or against the cognitive penetration of perception in either late or early vision. In order to do that we need to have recourse to brain imaging techniques. Thus, I introduce a neuroscientific study and argue that it seems to provide well-grounded evidence for the cognitive penetration of early vision in face perception. I also examine and reject alternative explanations to my conclusion. (shrink)

Construction process stages are argued to be vulnerable to the prevalence of corrupt practices. However, the validity of this argument has not been empirically explored in the extant literature of construction management. Therefore, this study examines the stages of the construction process susceptibility to corruption and its most prominent forms of corrupt activities. A total of forty-four project-related professionals were involved in an expert survey to assess such susceptibilities and the criticality of the identified corrupt activities at each stage. A (...) comparative study of expert views from developing regions against experts from developed regions is conducted. Expert scoring results revealed that three stages are most susceptible, namely: project execution, pre-qualification and tender stages. Such results were confirmed by application of the Mann–Whitney U test statistics tool, showing wide disparities in seven out of eleven identical stages. This study is intended to incite polemic discussions and greater empirical, evidence-based research from scholars in both developed and developing countries. This study adds to the extant literature corruption-related works on the construction process through deeper understanding of the dynamic nature of corrupt practices involved in the stages of the construction process in developing countries. Practically, it intends to offer a veritable plethora of information on the critical stages of the construction process for industry practitioners, policymakers and anti-corruption bodies to careen their attention towards the fight against corruption.

Smart-home technologies, comprising environmental sensors, wearables and video are attracting interest in home healthcare delivery. Development of such technology is usually justified on the basis of the technology’s potential to increase the autonomy of people living with long-term conditions. Studies of the ethics of smart-homes raise concerns about privacy, consent, social isolation and equity of access. Few studies have investigated the ethical perspectives of smart-home engineers themselves. By exploring the views of engineering researchers in a large smart-home project, (...) we sought to contribute to dialogue between ethics and the engineering community. Either face-to-face or using Skype, we conducted in-depth qualitative interviews with 20 early- and mid-career smart-home researchers from a multi-centre smart-home project, who were asked to describe their own experience and to reflect more broadly about ethical considerations that relate to smart-home design. With participants’ consent, interviews were audio-recorded, transcribed and analysed using a thematic approach. Two overarching themes emerged: in ‘Privacy’, researchers indicated that they paid close attention to negative consequences of potential unauthorised information sharing in their current work. However, when discussing broader issues in smart-home design beyond the confines of their immediate project, researchers considered physical privacy to a lesser extent, even though physical privacy may manifest in emotive concerns about being watched or monitored. In ‘Choice’, researchers indicated they often saw provision of choice to end-users as a solution to ethical dilemmas. While researchers indicated that choices of end-users may need to be restricted for technological reasons, ethical standpoints that restrict choice were usually assumed and embedded in design. The tractability of informational privacy may explain the greater attention that is paid to it. However, concerns about physical privacy may reduce acceptability of smart-home technologies to future end-users. While attention to choice suggests links with privacy, this may misidentify the sources of privacy and risk unjustly burdening end-users with problems that they cannot resolve. Separating considerations of choice and privacy may result in more satisfactory treatment of both. Finally, through our engagement with researchers as participants this study demonstrates the relevance of ethics as a critical partner to smart-home engineering. (shrink)

Considerable attention in bioethics has been devoted to moral expertise and its implications for handling applied moral problems. The existence and nature of moral expertise has been a contested topic, and particularly, whether philosophers are moral experts. In this study, we put the question of philosophers’ moral expertise in a wider context, utilizing a novel and global study among 4,087 philosophers from 96 countries. We find that despite the skepticism in recent literature, the vast majority of philosophers do believe in (...) moral expertise and in the contribution of philosophical training and experience to its acquisition. Yet, they still differ on what philosophers’ moral expertise consists of. While they widely accept that philosophers possess superior analytic abilities regarding moral matters, they diverge on whether they also possess improved ability to judge moral problems. Nonetheless, most philosophers in our sample believe that philosophers possess an improved ability to both analyze and judge moral problems and that they commonly see these two capacities as going hand in hand. We also point at significant associations between personal and professional attributes and philosophers’ beliefs, such as age, working in the field of moral philosophy, public involvement, and association with the analytic tradition. We discuss the implications of these findings for the debate about moral expertise. -/- . (shrink)

The predictive processing framework includes a broad set of ideas, which might be articulated and developed in a variety of ways, concerning how the brain may leverage predictive models when implementing perception, cognition, decision-making, and motor control. This article provides an up-to-date introduction to the two most influential theories within this framework: predictive coding and active inference. The first half of the paper (Sections 2–5) reviews the evolution of predictive coding, from early ideas about efficient coding in the visual (...) system to a more general model encompassing perception, cognition, and motor control. The theory is characterized in terms of the claims it makes at Marr's computational, algorithmic, and implementation levels of description, and the conceptual and mathematical connections between predictive coding, Bayesian inference, and variational free energy (a quantity jointly evaluating model accuracy and complexity) are explored. The second half of the paper (Sections 6–8) turns to recent theories of active inference. Like predictive coding, active inference models assume that perceptual and learning processes minimize variational free energy as a means of approximating Bayesian inference in a biologically plausible manner. However, these models focus primarily on planning and decision-making processes that predictive coding models were not developed to address. Under active inference, an agent evaluates potential plans (action sequences) based on their expected free energy (a quantity that combines anticipated reward and information gain). The agent is assumed to represent the world as a partially observable Markov decision process with discrete time and discrete states. Current research applications of active inference models are described, including a range of simulation work, as well as studies fitting models to empirical data. The paper concludes by considering future research directions that will be important for further development of both models. (shrink)

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)

As Jonathan Dancy points out, if we are tempted to think morality is a rational enterprise, we would expect moral judgments to be constrained by requirements of consistency. If our judgments and choices use general moral principles as guides or standards -- like the laws that feature in the explicit calculations of Immanuel Kant’s moral agent – we can be somewhat confident we respond to moral salience with consistency and, perhaps, rationally. For Kant, explicit reason ensures consistency because the explicit (...) application of maxims is autonomous from volatile external factors. Contemporary empirical studies in moral psychology show that when we respond morally we seemingly do so from emotion or intuition, not reason. For Kant, emotions and intuitions fluctuate with respect to volatile external factors. They are not the sort of things upon which we ought to base judgment and decision. If we hold the Kantian model true, we must assume that we fail to participate rationally in the moral enterprise. I argue against the Kantian model of moral cognition and turn to Aristotle to develop an account of moral cognition that allows us to retain our standing as rational moral agents. First, I argue for a particularist conception of moral reasons: I deny that the consistency required of a picture of morality as a rational enterprise requires our thought utilizes general moral rules. Next, I develop a particularist account of moral knowledge – a demand from their generalist opponents – by providing an account of moral perception. I subsequently argue that the deliverances of moral perception can constitute knowledge by providing a McDowellian account of perceptual justification. Lastly, I return to examine how the empirical work motivating the idea that we don’t participate in morality rationally. I show how none of these studies threatens the Aristotelian model as a viable alternative to the Kantian model. (shrink)
