Obviously perception is embodied. After all, if creatures were entirely disembodied, how could physical processes in the environment, such as the propagation of light or sound, be transduced into a neurobiological currency capable of generating experience? Is there, however, any deeper, more subtle sense in which perception is embodied? Perhaps. Alva Nos (2004) theory of enactive perception provides one proposal. Where it is commonly thought that.

Throughout the text, fundamental questions concerning the nature of visual perception are addressed.

The scientific community has debated the importance of “return” activities after ethnobiological studies. This issue has provoked debate because it touches on the ethics of research and the relationships with the people involved in these studies. This case study aimed to investigate community perception of an ethnobotany research project that was carried out in the semi-arid region of northeastern Brazil. Furthermore, we reported how the residents of this rural community felt about participating in the activities of “return” that arose from (...) the projects. Our findings demonstrate that “return” activities should be planned from the design phase of the research until its closure as a lifelong process that allows the communities involved to gradually take ownership of the information and actions that are being generated. Similarly, we argue that such activities must be negotiated with the people of the community so that they have decision-making power and autonomy to decide what is most relevant to their lives.

The frequency of earnings restatements has been increasing over the last decade. Restating previous earnings erodes perceived trustworthiness and competence of management, giving firms strong incentives to take actions to enhance perceived credibility of future financial reports [Farber, D. B.: 2005, The Accounting Review 80(2), 539–561.]. Using an experimental case, we examine the ability of post-restatement actions taken by a firm to positively influence non-professional investors’ perceptions of management’s financial reporting credibility. Our examination considers credibility judgments following two types of (...) restatements – those resulting from fraud in which the character, ethics, and values of an organization may be called into question [cf. Copeland, Jr., J. E.: 2005, Accounting Horizons 19(1), 35–43.], and those resulting from non-fraud (i.e., aggressive accounting). Based on the information in the experimental case, non-professional investors take the role of potential equity investors and make a judgment about management’s financial reporting credibility after reviewing a set of post-restatement actions taken by a firm. The possible actions include changes in four corporate governance mechanisms (i.e., internal audit function, external audit firm, board of directors, CFO) and a buyback of company stock. Our results provide an important contribution to the literature by demonstrating that among non-professional investors, perceptions of management’s financial reporting credibility are affected both by the post-restatement action taken and the nature of the restatement. These results offer insight into the formation of a key credibility judgment made by non-professional investors following a trust-destroying event, an earnings restatement. (shrink)

b>. The current essay introduces the guidance theory of representation, according to which the content and intentionality of representations can be accounted for in terms of the way they provide guidance for action. The guidance theory offers a way of fixing representational content that gives the causal and evolutionary history of the subject only an indirect (non-necessary) role, and an account of representational error, based on failure of action, that does not rely on any such notions as proper functions, ideal (...) conditions, or normal circumstances. Moreover, because the notion of error is defined in terms of failure of action, the guidance theory meets the. (shrink)

Recognizing the growing interdependence of the European Union and the importance of codes of conduct in companies’ operations, this research examines the effect of a country’s culture on the implementation of a code of conduct in a European context. We examine whether the perceptions of an activity’s ethicality relates to elements found in company codes of conduct vary by country or according to Hofstede’s (1980, Culture’s Consequences (Sage Publications, Beverly Hills, CA)) cultural constructs of: Uncertainty Avoidance, Masculinity/Femininity, Individualism, and Power (...) Distance. The 294 individuals, who participated in our study, were from 8 Western European countries. Their responses to our 13 scenarios indicate that differences in the perceptions of ethicality associate primarily with the participants’ country as opposed to their employer (i.e., accounting firm), employment level, or gender. The evidence also indicates that these country differences associate with Hofstede constructs of Individualism and Masculinity. (shrink)

Where in cognitive architecture do experiences of agency lie? This chapter defends the claim that such states qualify as a species of perception. Reference to ‘the sense of agency’ should not be taken as a mere façon de parler but picks out a genuinely perceptual system. The chapter begins by outlining the perceptual model of agentive experience before turning to its two main rivals: the doxastic model, according to which agentive experience is really a species of belief, and the telic (...) model, according to which agentive experience is really a species of agency. I conclude by defending the perceptual model against a number of objections to it, and by briefly exploring its implications for the question of how to approach the study of perception. (shrink)

The phenomenology of agency has, until recently, been rather neglected, overlooked by both philosophers of action and philosophers of consciousness alike. Thankfully, all that has changed, and of late there has been an explosion of interest in what it is like to be an agent. 1 This burgeoning field crosses the traditional boundaries between disciplines: philosophers of psychopathology are speculating about the role that unusual experiences of agency might play in accounting for disorders of thought and action; cognitive scientists are (...) developing models of how the phenomenology of agency is generated; and philosophers of mind are drawing connections between the phenomenology of agency and the nature of introspection, phenomenal character, and agency itself. My aim in this paper is not to provide an exhaustive survey of this recent literature, but to provide a.. (shrink)

This paper examines faculty perceptions regarding ethical behavior among colleagues and students, and faculty practices with regard to teaching ethics in three institutions over a 4-year period. Faculty reported an uneven pattern of unethical behavior among colleagues over the period. A majority of business courses included ethics, however as both a specific topic on the syllabus and within course discussions. The percentage of courses with ethics discussions increased in 2006, however, the time allocated to these discussions decreased. These results suggest (...) that faculty are approaching ethics instruction less formally, raising concerns over the success of curriculum integration. (shrink)

Evidence is presented for the notion that selection-for-perception and selection-for-action progress in parallel to become tightly coupled at the saccade target before the execution of the movement. Such a conception might be incorporated in the E-Z Reader model of eye-movement control in reading.

Though many philosophers of mind have taken an interest in the great developments in the brain sciences, the interest is seldom reciprocated by scientists, who frequently ignore the contributions philosophers have made to our understanding of the mind and brain. In a rare collaboration, a world famous brain scientist and an eminent philosopher have joined forces in an effort to understand how our brain interacts with the world. Does the brain behave as a calculator, combining sensory data before deciding how (...) to act? Or does it behave as an emulator endowed with innate models of the world, which it corrects according to the results of experiences obtained by the senses? The two authors come from very different backgrounds - the philosopher Jean-Luc Petit belongs to the philosophical tradition of Husserlian phenomenology. Alain Berthoz has long been interested in the physiology of action (movement, posture, decision-making, perception, etc.). Drawing on cutting-edge research from the cognitive sciences, the authors have produced a highly original volume showing how phenomenology and physiology can interact to further our understanding of the brain and the mind.

Sight and Embodiment in the Middle Ages breaks new ground by bringing postmodern writings on vision and embodiment into dialogue with medieval texts and images: an interdisciplinary strategy that illuminates and complicates both cultures. This is an invaluable reference work for anyone interested in the history and theory of visuality, and it is essential reading or scholars of art, science, or spirituality in the medieval period.

This is a charming and engaging book that combines careful attention to the phenomenology of experience with an appreciation of the psychology and neuroscience of perception. In some of its aimsfor example, to show problems with a rigid version of a view of visual perception as an inverse optics process of constructing a static 3-D representation from static 2-D information on the retina--it succeeds admirably. As No points out, vision is a process that depends on interactions between the perceiver and (...) the environment and involves contributions from sensory systems other than the eye. He is at pains to note that vision is not passive. His analogy with touch is to the point: touch involves skillful probing and movement, and so does vision, although less obviously and in my view less centrally so. This much is certainly widely accepted among vision scientistsalthough mainstream vision scientists (represented, for example, by Stephen Palmers excellent textbook²) view these points as best seen within a version of the inverse optics view that takes inputs as non-static and as including motor instructions (for example, involving eye movements and head movements).³ The kind of point that No raises is viewed as important at the margins, but as not disturbing the main lines of the picture of vision that descendswith many changesfrom the pioneering work of David Marr in the 1980s (and before him, from Helmholtz). But No shows little interest in mainstream vision science, focusing on non-mainstream ideas in the science of perception, specifically ideas from the anti-representational psychologist J.J. Gibson, and also drawing on Wittgenstein and the phenomenology tradition. There is a sense throughout the book of revolution, of upsetting the applecart. This is a review from the point of view of the applecart. (shrink)

I here present some doubts about whether Mandik’s (2010) proposed intermediacy and recurrence constraints are necessary and sufficient for agentive experience. I also argue that in order to vindicate the conclusion that agentive experience is an exclusively perceptual phenomenon (Prinz, 2007), it is not enough to show that the predictions produced by forward models of planned motor actions are conveyed by mock sensory signals. Rather, it must also be shown that the outputs of “comparator” mechanisms that compare these predictions against (...) actual sensory feedback are also coded in a perceptual representational format.

Neuropsychological findings used to motivate the “two visual systems” hypothesis have been taken to endanger a pair of widely accepted claims about spatial representation in conscious visual experience. The first is the claim that visual experience represents 3-D space around the perceiver using an egocentric frame of reference. The second is the claim that there is a constitutive link between the spatial contents of visual experience and the perceiver’s bodily actions. In this paper, I review and assess three main sources (...) of evidence for the two visual systems hypothesis. I argue that the best interpretation of tbe evidence is in fact consistent with both claims. I conclude with some brief remarks on the relation between visual consciousness and rational agency.

In this paper, I critically assess the enactive account of visual perception recently defended by Alva Noë (2004). I argue inter alia that the enactive account falsely identifies an object’s apparent shape with its 2D perspectival shape; that it mistakenly assimilates visual shape perception and volumetric object recognition; and that it seriously misrepresents the constitutive role of bodily action in visual awareness. I argue further that noticing an object’s perspectival shape involves a hybrid experience combining both perceptual and imaginative elements (...) – an act of what I call ‘make-perceive.’. (shrink)

David Milner and Melvyn Goodale’s dissociation hypothesis is commonly taken to state that there are two functionally specialized cortical streams of visual processing originating in striate (V1) cortex: a dorsal, action-related “unconscious” stream and a ventral, perception-related “conscious” stream. As Milner and Goodale acknowledge, findings from blindsight studies suggest a more sophisticated picture that replaces the distinction between unconscious vision for action and conscious vision for perception with a tripartite division between unconscious vision for action, conscious vision for perception, and (...) unconscious vision for perception. The combination excluded by the tripartite division is the possibility of conscious vision for action. But are there good grounds for concluding that there is no conscious vision for action? There is now overwhelming evidence that illusions and perceived size can have a significant effect on action (Bruno & Franz, 2009; Dassonville & Bala, 2004; Franz & Gegenfurtner, 2008; McIntosh & Lashley, 2008). There is also suggestive evidence that any sophisticated visual behavior requires collaboration between the two visual streams at every stage of the process (Schenk & McIntosh, 2010). I nonetheless want to make a case for the tripartite division between unconscious vision for action, conscious vision for perception, and unconscious vision for perception. My aim here is not to refute the evidence showing that conscious vision can affect action but rather to argue (a) that we cannot gain cognitive access to action-guiding dorsal stream representations, and (b) that these representations do not correlate with phenomenal consciousness. This vindicates the semi-conservative view that the dissociation hypothesis is best understood as a tripartite division. (shrink)

This volume provides an up to date and comprehensive overview of the philosophy and neuroscience movement, which applies the methods of neuroscience to traditional philosophical problems and uses philosophical methods to illuminate issues in neuroscience.

Essays in (...) this volume are clustered around five major themes: data and theory in neuroscience; neural representation and computation; visuomotor transformations; color vision; and consciousness.

This is the first book to explore the cognitive science of effortless attention and action. Attention and action are generally understood to require effort, and the expectation is that under normal circumstances effort increases to meet rising demand. Sometimes, however, attention and action seem to flow effortlessly despite high demand. Effortless attention and action have been documented across a range of normal activities--from rock climbing to chess playing--and yet fundamental questions about the cognitive science of effortlessness have gone largely unasked. (...) -/- This book draws from the disciplines of cognitive psychology, neurophysiology, behavioral psychology, genetics, philosophy, and cross-cultural studies. Starting from the premise that the phenomena of effortless attention and action provide an opportunity to test current models of attention and action, leading researchers from around the world examine topics including effort as a cognitive resource, the role of effort in decision making, the neurophysiology of effortless attention and action, the role of automaticity in effortless action, expert performance in effortless action, and the neurophysiology and benefits of attentional training. -/- Contributors: Joshua M.

This exploratory study examines how managers and professionals regard the ethical and social responsibility reputations of 60 well-known Australian and International companies, and how this in turn influences their attitudes and behaviour towards these organisations. More than 350 MBA, other postgraduate business students, and participants in Australian Institute of Management (Western Australia) management education programmes were surveyed to evaluate how ethical and socially responsible they believed the 60 organisations to be. The survey sought to determine what these participants considered ‘ethical’ (...) and ‘socially responsible’ behaviour in organisations to be. The survey also examined how the participants’ beliefs influenced their attitudes and intended behaviours towards these organisations. The results of this survey indicate that many managers and professionals have clear views about the ethical and social responsibility reputations of companies. This affects their attitudes towards these organisations which in turn has an impact on their intended behaviour towards them. These findings support the view in other research studies that well-educated managers and professionals are, to some extent, taking into account the ethical and social responsibility reputations of companies when deciding whether to work for them, use their services or buy shares in their companies.

Little is known about distance processing in patients with posterior brain damage. Although many investigators have claimed that distance estimates are normal or abnormal in some of these patients, many of these observations were made informally and the examiners often asked for relative, and not absolute, distance estimates. The present investigation served two purposes. First, we wanted to contrast the use of distance information in peripersonal space for perceptual report as opposed to visuomotor control in our visual form agnosic patient, (...) DF. Second, we wanted to see to what extent her abilities to process distance cues were dependent on binocular vision, in light of Milner et al.'s (1991) observations of preserved stereopsis in DF, and Dijkerman et al.'s (1996) and Marotta et al.'s (1997) observations that her visual guidance of grasping may be particularly dependent on binocular vision of the target. We hypothesized that DF's visuomotor responses would show normal sensitivity to target distance, while her perceptual estimates would not. In the first experiment, we required DF and two age- and sex-matched control subjects to reach out and grasp black cubes placed at varying distances, or to estimate the distance of the cubes from the hand starting position without making a reaching movement. In the second experiment, we required DF and two age-matched control subjects to point as rapidly and accurately as possible to small LED targets which differed in spatial location, under binocular and monocular conditions. The results showed that, relative to the control subjects, DF's grasping movements produced normal peak velocity-distance scaling-when she reached for blocks which varied in depth or pointed to LED targets which were presented at different distances in depth. In contrast, in the cube experiment, her verbal estimates of object distance were poorly scaled, although they improved slightly under the binocular conditions. The results are discussed in terms of current theories of processing streams in extrastriate visual cortex and the distinction between categorical and coordinate spatial processing. (shrink)

This article offers an overview of the structure and significance of Merleau-Ponty's phenomenology. Neither a psychological nor an epistemological theory, Merleau-Ponty's Phenomenology of Perception is instead an attempt to describe perceptual experience as we experience it. Although he was influenced heavily by Husserl, Heidegger, and Gestalt psychology, his work departs significantly from all three. Particularly original is his account of our bodily, precognitive experience of other persons, which he argues is essentially more primitive than any belief or doubt we can (...) raise concerning the contents or even the existence of their minds. I conclude with a discussion of the differences between Merleau-Ponty's phenomenology and Alva Noë's more recent 'enactive' theory of perception. (shrink)

I distinguish between two kinds of sensorimotor expectations: agent- and object-active ones. Alva Noë's answer to the problem of how perception acquires volumetric content illicitly privileges agent-active expectations over object-active expectations, though the two are explanatorily on a par. Considerations which Noë draws upon concerning how organisms may ‘off-load’ internal processes onto the environment do not support his view that volumetric content depends on our embodiment; rather, they support a view of experience which is restrictive of the body's role in (...) perception. My objections undercut central arguments which Noë gives for his brand of enactivism. (shrink)

In recent years, neurophysiological evidence has accumulated in favor of a common coding between perception and execution of action. We review findings from recent neuroimaging experiments in the action domain with three complementary perspectives: perception of action, covert action triggered by perception, and reproduction of perceived action (imitation). All studies point to the parietal cortex as a key region for body movement representation, both observed and performed.

In her essay --?Information, Perception and Action--, Claire Michaels reaches two conclusions that run very much against the grain of ecological psychology. First, she claims that affordances are not perceived, but simply acted upon; second, because of this, perception and action ought to be conceived separately. These conclusions are based upon a misinterpretation of empirical evidence which is, in turn, based upon a conflation of two proper objects of perception: objectively with properties and affordances.

Perceptual learning mechanisms derived from Hebb's theory of cell assemblies can generate prototypic representations capable of extending the representational power of TEC (Theory of Event Coding) event codes. The extended capability includes categorization that accommodates “family resemblances” and problem solving that uses cognitive maps.

In _Action in Perception _Alva No develops and presents a sensorimotor account of vision and of visual consciousness. According to such an account seeing (and indeed perceiving more generally) is analysed as a kind of skilful bodily activity. Such a view is consistent with the emerging emphasis, in both philosophy and cognitive science, on the critical role of embodiment in the construction of intelligent agency. I shall argue, however, that the full sensorimotor model faces three important challenges. The first is (...) to negotiate a path between two prima facie unsatisfactory readings of the central claim that conscious perceptual experience is constituted by knowledge of patterns of sensorimotor dependence. The second is to convince us that the sensorimotor contribution, in such cases, is actually constitutive of perceptual experience rather than merely causally implicated in the origination of such experience.² And the third is to respond to the important challenge raised by what I will dub 'sensorimotor summarizing' models of the relation between conscious experience and richly detailed sensorimotor routines. According to such models³ conscious perceptual experience only rather indirectly reflects the rich detail of our actual sensorimotor engagements, which are instead lightly sampled as a coarse guide, optimized for planning and reasoning, and geared and filtered according to current needs and purposes.

We seem, or so it seems to some theorists, to experience a rich stream of highly detailed information concerning an extensive part of our current visual surroundings. But this appearance, it has been suggested, is in some way illusory. Our brains do not command richly detailed internal models of the current scene. Our seeings, it seems, are not all that they seem. This, then, is the Grand Illusion. We think we see much more than we actually do. In this paper (...) I shall (briefly) rehearse the empirical evidence for this rather startling claim, and then critically examine a variety of responses. One especially interesting response is a development of the so-called ‘skill theory’, according to which there is no illusion after all. Instead, so the theory goes, we establish the required visual contact with our world by an ongoing process of active exploration, in which the world acts as a kind of reliable, interrogable, external memory (Noe, Pessoa and.

How should we characterize the functional role of conscious visual experience? In particular, how do the conscious contents of visual experience guide, bear upon, or otherwise inform our ongoing motor activities? According to an intuitive and (I shall argue) philosophically influential conception, the links are often quite direct. The contents of conscious visual experience, according to this conception, are typically active in the control and guidance of our fine-tuned, real-time engagements with the surrounding three-dimensional world. But this idea (which I (...) shall call the Assumption of Experience-Based Control) is hostage to empirical fortune. It is a hostage, moreover, whose safety is in serious doubt. Thus Milner and Goodale (1995) argue for a deep and abiding dissociation between the contents of conscious seeing, on the one hand, and the resources used for the on-line guidance of visuo-motor action, on the other. This ‘dual visual systems’ hypothesis, which finds many echoes in various other bodies of cognitive scientific research, poses a prima facie challenge to the Assumption of Experience-Based Control. More importantly, it provides (I shall argue) fuel for an alternative and philosophically suggestive account of the functional role of conscious visual experience. (shrink)

Recent work in "embodied, embedded" cognitive science links mental contents to large-scale distributed effects: dynamic patterns implicating elements of (what are traditionally seen as) sensing, reasoning and acting. Central to this approach is an idea of biological cognition as profoundly "action-oriented" - geared not to the creation of rich, passive inner models of the world, but to the cheap and efficient production of real-world action in real-world context. A case in point is Hurley's (1998) account of the profound role of (...) motor output in fixing the contents of conscious visual awareness - an account that also emphasizes distributed vehicles and long-range dynamical loops. Such stories can seem dramatically opposed to accounts, such as Milner and Goodale (1995), that stress relatively local mechanisms and that posit firm divisions between processes of visual awareness and of visuomotor action. But such accounts, I argue, can be deeply complimentary and together illustrate an important lesson. The lesson is that cognition may be embodied and action-oriented in two distinct - but complimentary - ways. There is a way of being embodied and action-oriented that implies being closely geared to the fine-grained control of low level effectors (hands, arms, legs and so on). And there is a way of being embodied and action-oriented that implies being closely geared to gross motor intentions, current goals, and schematic motor plans. Human cognition, I suggest, is embodied and action-oriented in both these ways. But the neural systems involved, and the size and scope of the key dynamic loops, may be quite different in each case.

O'Regan and Noe present a wonderfully detailed and comprehensive defense of a position whose broad outline we absolutely and unreservedly endorse. They are right, it seems to us, to stress the intimacy of conscious content and embodied action, and to counter the idea of a Grand Illusion with the image of an agent genuinely in touch, via active exploration, with the rich and varied visual scene. This is an enormously impressive achievement, and we hope that the comments that follow will (...) be taken in a spirit of constructive questioning. Overall, we have two main reservations. (shrink)

This paper defends a dynamic model of the way in which perception is integrated with action, a model I refer to as ‘the navigational account’. According to this account, employing vision and other forms of distance perception, a creature acquires information about its surroundings via the senses, information that enables it to select and navigate routes through its environment, so as to attain objects that satisfy its needs. This form of perceptually guided activity should be distinguished from other kinds of (...) semi-automatic responses to visual stimuli that do not necessarily involve conscious experiences. It essentially involves inner states, which involve both the awareness of phenomenal qualities, and also a representational component. The navigational account is compared here with the enactive approach to perception, which opposes the view that perceptual experiences are inner states. This paper argues that a full account of perception raises a number of different questions. One central explanatory project concerns questions about the kinds of processes that currently enable a creature to identify and respond appropriately to distant objects: the answer, it is argued, lies in acknowledging the role of conscious inner representations in guiding navigational behaviour through complex environments. The fact that perception and action are interdependent does not conflict with the claim that inner representational states comprise an essential stage in visual processing. (shrink)

This report highlights and explores five questions that arose from the Network for Sensory Research workshop on perceptual learning and perceptual recognition at the University of York on March 19th and 20th, 2012: 1. What is perceptual learning? 2. Can perceptual experience be modified by reason? 3. How does perceptual learning alter perceptual phenomenology? 4. How does perceptual learning alter the contents of perception? 5. How is perceptual learning coordinated with action?

A range of arguments are presented to demonstrate that (1) human visual orientations are conceptually constituted (concept?bound); (2) the concept?boundedness of visual orientations does not require a cognitivist account according to which a mental process of ?inference? or of ?interpretation? must be postulated to accompany a purely ?optical? registration of ?wavelengths of light?, ?photons?, or contentless ?information'; (3) concept?bound visual orientations are not all instances of ?seeing as?, contrary to some currently prominent cognitivist accounts; (4) the dispute between cognitivist and (...) realist accounts about the phenomenon of ?seeing as? is spurious, and is based upon a confusion about the fundamental analytical distinction made by Wittgenstein between ?seeing? and ?seeing as'; (5) ?perceiving?, ?seeing?, and ?seeing as? are but three of a large array of verbs of human visual orientation, and are not ?master categories? under which one can subsume these other modalities; (6) one cannot deduce a continuity of human visual orientation from a continuity of photon?photoreceptor interaction, a point we characterize as the ?staggered character? of human visual orientations; (7) detailed attention to the grammars of the diverse verbs of human visual orientation can open up a domain of study which we here refer to as a ?praxiology of perception'; (8) the nature of such an inquiry can be illustrated with exemplary reference to the analysis of the properties of ?noticing? as embedded in courses of practical action; and (9) such arguments, which claim that existing perceptual theories overly homogenize what is involved in visual orientations to the world, parallel those of Stroll, who proposes that standard accounts of ?what is perceived? overly homogenize the perceptible environment.

Reflection on cases involving the occurrence of various types of perceptual activity suggests that the phenomenal character of perceptual experience can be partly determined by agential factors. I discuss the significance of these kinds of case for the dispute about phenomenal character that is at the core of recent philosophy of perception. I then go on to sketch an account of how active and passive elements of phenomenal character are related to one another in activities like watching and looking at (...) things. (shrink)

There has been relatively little discussion, in contemporary philosophy of mind, of the active aspects of perceptual processes. This essay presents and offers some preliminary development of a view about what it is for an agent to watch a particular material object throughout a period of time. On this view, watching is a kind of perceptual activity distinguished by a distinctive epistemic role. The essay presents a puzzle about watching an object that arises through elementary reflection on the consequences of (...) two apparent truths about watching an object throughout a period of time. It proposes that the puzzle can be resolved by a view according to which for an agent to watch an object throughout a period of time is for that agent to maintain visual awareness of that object with the aim of perceptually knowing what that object is doing. The essay goes on to make some further suggestions about how the apparatus developed in connection with the notion of watching may enable us to offer related explanations of other kinds of perceptual activity. It proposes that a useful distinction can be drawn between perceptual activities like watching which have as their aim knowledge of what an object is doing and activities like looking or visually scrutinizing which have as their aims knowledge of the states or conditions of the objects of perceptual awareness.

The self seems to be a unitary entity remaining stable across time. Nevertheless, current theorizing conceptualizes the self as a number of interacting sub-systems involving perception, intention and action (self-model). One important function of such a self-model is to distinguish between events occurring as a result of one's own actions and events occurring as the result of somebody else's actions. We conducted an fMRI experiment that compared brain activation after an abrupt mismatch between one's own movement and its visual consequences (...) with an abrupt mismatch between one's own movement and somebody else's visually perceived hand movement. A right fronto-parietal network was selectively active during a sudden mismatch between one's own observed and performed hand action. (shrink)

This study aimed at evaluating the role of proprioception in the process of matching the final position of one's limbs with an intentional movement. Two experiments were realised with the same paradigm of conscious recognition of one's own limb position from a distorted position. In the first experiment, 22 healthy subjects performed the task in an active and in a passive condition. In the latter condition, proprioception was the only available information since the central signals related to the motor command (...) were likely to be absent. The second experiment was realised with a deafferented patient who suffers from a complete haptic deafferentation, including loss of proprioception. The results first argue in favour of a dominant role of proprioception in action recognition, but they also stress the possible role of central signals. The process of matching the final position of one's limbs with an intended movement and thus of action recognition would be achieved through a comparison process between the predicted sensory consequences of the action, which are stored in its internal model, and the actual sensory consequences of that action.

I contend that Alva Noë’s Enactive Approach to Perception fails to give an adequate account of the periphery of attention. Noë claims that our peripheral experience is not produced by the brain’s representation of peripheral items, but rather by our mastery of sensorimotor skills and contingencies. I offer a two-pronged assault on this account of the periphery of attention. The first challenge comes from Mack and Rock’s work on inattentional blindness, and provides robust empirical evidence for the semantic processing (and (...) hence representation) of some wholly unattended stimuli. The second challenge draws on LaBerge’s theory of attention to provide a substantial advantage to peripheral representations, saving time whenever we shift the focus of our attention to something which had been in the periphery, allowing us to respond to that thing more quickly than would be possible if Noë’s account of perception were correct.

Questions about the relation between mind and world have long occupied philosophers of mind. In _Consciousness in Action_ Susan Hurley invites us to adopt a ninety-degree shift and consider the relation between perception and action. The central theme of the book is an attack on what Hurley dubs the _Input-Output Picture_ of perception and actionthe picture of perceptions as sensory inputs to the cognitive system and intentions as motor outputs from it, with the mind occupying the buffer zone in between. (...) Hurley argues that this picture confuses the personal level of normatively constrained mental contents and the subpersonal level of causal processes sustaining the mind. The notions of perception and action belong to the former, those of input and output to the latter. In place of the Input-Output picture, Hurley proposes a _Two-level _ _Interdependence View_. At the subpersonal level, she points out, there are not only one-way processes from input to output but also a host of feedback loops from output to inputsome internal to the central nervous system, some of wider orbit, involving proprioception, for example, or visual feedback on movement. The system as a whole can be seen as a _dynamical singularity_a tangle of sensorimotor feedback loops centred on the organism but extending out into the world beyond. The processes at this level are the vehicles of perceptions and actions, but, Hurley insists, the two levels cannot be mapped onto each other in a simple way. Changes on the output side may affect the content of perceptions, and changes on the input side may affect that of intentions. Perception and intention are in this way _interdependent_. The point here is not the uncontroversial one that perceptions and intentions can _cause_ changes in each other. That would be compatible with the Input-Output Picture. The dependency, in Hurleys view, is not instrumental, but _constitutive_: the contents of perceptions and intentions are each constituted by processes involving both inputs and outputs.. (shrink)

In a New York Times article last month, entitled Cells that read minds, the neuroscience reporter, Sandra Blakeslee (January 10, 2006) provided a list of all the things that mirror neurons can explain. As we know, mirror neurons, discovered by Rizzolattis group in Parma, are neurons that are activated when we engage in action, and when we perceive intentional movement in another person. According to Blakeslee and the scientists she interviewed, mirror neurons explain not only how we are capable of (...) understanding another persons actions, but also language, empathy, how children learn, why people respond to certain types of sports, dance, music and art, why watching media violence may be harmful and why many men like pornography. Let me set aside the controversial questions about whether mirror neurons can explain all of these things, and accept that mirror neurons are clearly smart little cells. But let me ask whether Blakeslee and her scientists are expressing things in the right way. (shrink)

This paper contrasts two enactive theories of visual experience: the sensorimotor theory (O’Regan and Noë, Behav Brain Sci 24(5):939–1031, 2001; Noë and O’Regan, Vision and mind, 2002; Noë, Action in perception, 2004) and Susan Hurley’s (Consciousness in action, 1998, Synthese 129:3–40, 2001) theory of active perception. We criticise the sensorimotor theory for its commitment to a distinction between mere sensorimotor behaviour and cognition. This is a distinction that is firmly rejected by Hurley. Hurley argues that personal level cognitive abilities emerge (...) out of a complex dynamic feedback system at the subpersonal level. Moreover reflection on the role of eye movements in visual perception establishes a further sense in which a distinction between sensorimotor behaviour and cognition cannot be sustained. The sensorimotor theory has recently come under critical fire (see e.g. Block, J Philos CII(5):259–272, 2005; Prinz, Psyche, 12(1):1–19, 2006; Aizawa, J Philos CIV(1), 2007) for mistaking a merely causal contribution of action to perception for a constitutive contribution. We further argue that the sensorimotor theory is particularly vulnerable to this objection in a way that Hurley’s active perception theory is not. This presents an additional reason for preferring Hurley’s theory as providing a conceptual framework for the enactive programme. (shrink)

A network sample of 162 employees from across the U.S. was studied to assess the relationship between individual spirituality and perceptions of unethical business activities. Analyses indicate that degree of individual spirituality influences whether an individual perceives a questionable business practice as ethical or unethical. Ramifications of these findings regarding the role of spirituality in enhancing workplace ethicality, as well as directions for future research, are discussed.

Deictic coding offers a useful model for understanding the interactions between the dorsal and ventral streams of visual processing in the cerebral cortex. By extending Ballard et al.'s ideas on teleassistance, I show how dedicated low-level visuomotor processes in the dorsal stream might be engaged for the services of high-level cognitive operations in the ventral stream.

I present an account of how agents can know what they are doing when they intentionally execute object-oriented actions. When an agent executes an object-oriented intentional action, she uses perception in such a way that it can fulfil a justificatory role for her knowledge of her own action and it can fulfil this justificatory role without being inferentially linked to the cognitive states that it justifies. I argue for this proposal by meeting two challenges: in an agent's knowledge of her (...) action perception can only play an enabling role (and no justificatory role) for the agent's knowledge and if perception has a justificatory role, then the agent's knowledge must be inferential.

An attempt is made to defend a general approach to the spatial content of perception, an approach according to which perception is imbued with spatial content in virtue of certain kinds of connections between perceiving organism's sensory input and its behavioral output. The most important aspect of the defense involves clearly distinguishing two kinds of perceptuo-behavioral skills—the formation of dispositions, and a capacity for emulation. The former, the formation of dispositions, is argued to by the central pivot of spatial content. (...) I provide a neural information processing interpretation of what these dispositions amount to, and describe how dispositions, so understood, are an obvious implementation of Gareth Evans' proposal on the topic. Furthermore, I describe what sorts of contribution are made by emulation mechanisms, and I also describe exactly how the emulation framework differs from similar but distinct notions with which it is often unhelpfully confused, such as sensorimotor contingencies and forward models.

Inspired by the writings of J. M. Hinton (1967a, 1967b, 1973), but ushered into the mainstream by Paul Snowdon (1980–1, 1990–1), John McDowell (1982, 1986), and M. G. F. Martin (2002, 2004, 2006), disjunctivism is currently discussed, advocated, and opposed in the philosophy of perception, the theory of knowledge, the theory of practical reason, and the philosophy of action. But what is disjunctivism?

O'Regan & Noë mistakenly identify visual processing with visual experience. I outline some reasons why this is a mistake, taking my data and arguments mainly from the literature on subliminal processing.

Alva Noë is a modern-day empiricist. His book Action in Perception is chockablock with contemporary cognitive science; its preface and notes (not to mention general erudition) point to on-going collaboration with Evan Thompson, Kevin O’Regan, and Susan Hurley. Their research investigates the sensorimotor bases of consciousness, and Action in Perception is offered as its philosophical backdrop. As such, the book presents a series of ideas and interpretations that constitute what Noë calls the “enactive approach” to perception, many of which are (...) explicitly phenomenological in orientation. So those on the lookout for imaginative philosophy of mind will find Noë's work particularly compelling. (Noë would prefer "already feeling about for imaginative philosophy of mind," because on his account paradigmatic perceptual activity is tactile rather than visual.) In this review I will not address the empirical details concerning Noë and his compatriots, but will instead focus on the way Noë’s enactive approach should be situated vis-à-vis traditional phenomenology. Action in Perception is part of the grand project of a robustly scientific knowledge of human perceptual experience, but it is clearly also a philosophical theory, so I will address it philosophically. I address it as I take it to be: one of the best works in the philosophy of perception to appear in a very long time. (shrink)

Lehar's revival of phenomenology and his all-encompassing Gestalt Bubble model are ambitious and stimulating. I offer an illustrated caution about phenomenology, a more fractured alternative to his Bubble model, and two lines of phenomena that may disqualify his isomorphism. I think a perceptual-inquiry model can contend.

The theoretical proposal that perceptual experience be thought of as expectancies about sensorimotor contingencies, rather than as expressions of mental representations, is endorsed; examples that effectively enforce that view are discussed; and one example (of perceptual coupling) that seems to demand a mental representation, with all of the diagnostic value such a tool would have, is raised for consideration.

Traditional approaches to human information processing tend to deal with perception and action planning in isolation, so that an adequate account of the perception-action interface is still missing. On the perceptual side, the dominant cognitive view largely underestimates, and thus fails to account for, the impact of action-related processes on both the processing of perceptual information and on perceptual learning. On the action side, most approaches conceive of action planning as a mere continuation of stimulus processing, thus failing to account (...) for the goal-directedness of even the simplest reaction in an experimental task. We propose a new framework for a more adequate theoretical treatment of perception and action planning, in which perceptual contents and action plans are coded in a common representational medium by feature codes with distal reference. Perceived events (perceptions) and to-be-produced events (actions) are equally represented by integrated, task-tuned networks of feature codes – cognitive structures we call event codes. We give an overview of evidence from a wide variety of empirical domains, such as spatial stimulus-response compatibility, sensorimotor synchronization, and ideomotor action, showing that our main assumptions are well supported by the data. Key Words: action planning; binding; common coding; event coding; feature integration; perception; perception-action interface. (shrink)

The theory presented here is a near neighbour of Humphrey's theory of sensations as actions. O'Regan & Noë have opened up remarkable new possibilities. But they have missed a trick by not making more of the distinction between sensation and perception; and some of their particular proposals for how we use our eyes to represent visual properties are not only implausible but would, if true, isolate vision from other sensory modalities and do little to explain the phenomenology of conscious experience (...) in general. (shrink)

We present work demonstrating that the nature of an object for our visual system depends on the actions we are programming and on the presence of action relations between stimuli. For example, patients who show visual extinction are more likely to become aware of two objects if the objects fall in appropriate visual locations for a common action. This effect of the action relations between objects is modulated both by the familiarity of the positioning of the objects for action, and (...) by the mere possibility of action (the ‘affordance’) between the objects. In addition, the programming of an action to a part of an object alters the representation of that object, making the ‘part’ into the object selected by the visual system. These results point to object coding being a rather flexible process, affected not only by the perceptual properties of stimuli but also by the relations between these properties and action. We discuss the implications for theories of perception as well as considering why action information, in particular, may be important for perception. (shrink)

Recently research on imitation and its role in social cognition has been flourishing across various disciplines. After briefly reviewing these developments under the headings of behavior, subpersonal mechanisms, and functions of imitation, I advance the _shared circuits_.

Philosophy of neuroscience may seem an odd thing to do. What can a philosopher add to what neuroscience itself has to say, other than at some very abstract level, far removed from empirical details and the interests of scientists? At some point you take a deep breath, acknowledge the methodological questions, and just go ahead, spurred on by the sheer philosophical interest and excitement abroad in the neurosciences today. So it is very gratifying to a philosopher of neuroscience for such (...) a distinguished neuropsychologist as Marcel Kinsbourne to find added value in the result. (shrink)

A traditional view of perception and action makestwo assumptions: that the causal flow betweenperception and action is primarily linear or one-way,and that they are merely instrumentally related toeach other, so that each is a means to the other.Either or both of these assumptions can be rejected.Behaviorism rejects the instrumental but not theone-way aspect of the traditional view, thus leavingitself open to charges of verificationism. Ecologicalviews reject the one-way aspect but not theinstrumental aspect of the traditional view, so thatperception and (...) action are seen as instrumentallyinterdependent. It is argued here that a betteralternative is to reject both assumptions, resultingin a two-level interdependence view in whichperception and action co-depend on dynamicallycircular subpersonal relations and as a result may bemore than merely instrumentally interdependent. Thisis illustrated by reference to motor theories ofperception and control theories of action. (shrink)

Certain empirical results suggest a way of challenging two natural and widespread assumptions about the mind. One assumption is about the relations between perception and action. This shows up in the widespread conception of perception and action in terms of input and output, respectively. Perception is conceived as input from world to mind and action is conceived as output from mind to world. The other assumption is about the relations between mind and world. It influences various opposed views about whether (...) the contents of the mind are in principle independent of the outside world. (shrink)

The binary divide between traditional cognitivist and enactivist paradigms is tied to their respective commitments to understanding cognition as based on knowing that as opposed to knowing how. Using O’Regan’s and No¨e’s landmark sensorimotor contingency theory of perceptual experience as a foil, I demonstrate how easy it is to fall into conservative thinking. Although their account is advertised as decidedly ‘skill-based’, on close inspection it shows itself to be riddled with suppositions threatening to reduce it to a rules-and-representations approach. To (...) remain properly enactivist it must be purged of such commitments and indeed all commitment to mediating knowledge: it must embrace a more radical enactivism. (shrink)

We explore the understanding of conscious states in terms of spatio-temporal dynamics through modelling a mobile agent. Conscious states are associated with an agent's spontaneous and deterministic fluctuation between attachment to and detachment from the surroundings. It is because of this fluctuating nature, we argue, that an agent can perceive structure in the world. Perception requires a conscious state in physical devices. This is a central concern of this paper, and we examine it by simulating a mobile agent equipped with (...) an interconnected Fitz-Hugh-Nagumo (FHN) neuron network with delayed signal transmissions. The agent can move around a space by sensing the environment pattern through the input neurons and computing the motor outputs via the FHN network. The agent shows a variety of motion styles and a spontaneous selection of motion styles responding to the surroundings. Such a phenomenon is named embodied chaotic itinerancy (ECI), as an extension of chaotic itinerant dynamics, which is known to be a typical dynamic with a high degree of freedom. We take this selective mode of response to be significant, particularly those interacting with spatial pattern, as an inevitable property of conscious states. (shrink)

The present paper analyzes the regularities referred to via the concept 'self.' This is important, for cognitive science traditionally models the self as a cognitive mediator between perceptual inputs and behavioral outputs. This leads to the assertion that the self causes action. Recent findings in social psychology indicate this is not the case and, as a consequence, certain cognitive scientists model the self as being epiphenomenal. In contrast, the present paper proposes an alternative approach (i.e., the event-control approach) that is (...) based on recently discovered regularities between perception and action. Specifically, these regularities indicate that perception and action planning utilize common neural resources. This leads to a coupling of perception, planning, and action in which the first two constitute aspects of a single system (i.e., the distal-event system) that is able to pre-specify and detect distal events. This distal-event system is then coupled with action (i.e., effector-control systems) in a constraining, as opposed to 'causal' manner. This model has implications for how we conceptualize the manner in which one infers the intentions of another, anticipates the intentions of another, and possibly even experiences another. In conclusion, it is argued that it may be possible to map the concept 'self' onto the regularities referred to in the event-control model, not in order to reify 'the self' as a causal mechanism, but to demonstrate its status as a useful concept that refers to regularities that are part of the natural order.

Alva Noë’s version of the enactive conception in _Action in Perception_ is an important contribution to the study of visual perception. First, I argue, however, that it is unclear (at best) whether, as the enactivists claim, work on change blindness supports the denial of the existence of detailed visual representations. Second, I elaborate on what Noë calls the ‘puzzle of perceptual presence’. Thirdly, I question the enactivist account of perceptual constancy. Finally, I draw attention to the tensions between enactivism and (...) two trends in cognitive neuroscience: the two-visual systems model of human vision and the theory of internal forward models of action.
