Frost presents an explanatory theory of reading that generalizes across several languages, based on a revised role of orthographic coding. Perceptual and psychophysical evidence indicates a decay of letter position encoding as a function of the eccentricity of letters ; this factor may account for some of the differences in the languages considered by Frost.

This paper replies to objections from perceptual distortion against the representationalist thesis that the phenomenal characters of experiences supervene on their intentional contents. It has been argued that some pairs of distorted and undistorted experiences share contents without sharing phenomenal characters, which is incompatible with the supervenience thesis. In reply, I suggest that such cases are not counterexamples to the representationalist thesis because the contents of distorted experiences are always impoverished in some way compared to those of normal experiences. (...) This can be shown by considering limit cases of perceptual distortion, for example, maximally blurry experiences, which manifestly lack details present in clear experiences. I argue that since there is no reasonable way to draw the line between distorted experiences that have degraded content and distorted experiences that do not, we should allow that an increase in distortion is always accompanied by a change in content. This applies to perceptual distortions due to blur, double vision, perspective, and illumination conditions. (shrink)

My first aim in this paper is to show that the transparency claim cannot serve the purpose to which it is assigned; that is, the idea that perceptual experience is transparent is no help whatsoever in motivating an externalist account of phenomenal character. My second aim is to show that the internalist qualia theorist's response to the transparency idea has been unnecessarily concessive to the externalist. Surprisingly, internalists seem to allow that much of the phenomenal character of perceptual (...) experience depends essentially (and not just causally) upon externally located properties. They argue that we can also be aware of internal, non-intentional qualia. I present an alternative response the internalist can make to the transparency claim: phenomenal character is wholly internal, and seeming to be aware of externally located properties just is being aware of internally constituted experiential features.

The perceptual symbol approach to knowledge representation combines structured frames and dynamic imagery. The perceptual symbol approach provides a good account of the representation of scientific models, of some types of naive theories held by children and adults, and of certain reconstructive memory phenomena. The ontological status of perceptual symbols is unclear and this form of representation does not succeed in accounting for all forms of human knowledge.

Common sense takes the physical world to be populated by mind-independent particulars. Why and with what right do we hold this view? Early phenomenologists argue that the common sense view is our natural starting point because we experience objects as mind-independent. While it seems unsurprising that one can perceive an object being red or square, the claim that one can experience an object as mind-independent is controversial. In this paper I will articulate and defend the claim that we can experience (...) mind-independence by mainly drawing on the work of the Gestalt psychologist Karl Duncker who, in turn, built on Husserl’s work. In the development of this claim the notion of a limit – either a maximum or minimum – of perception will play an important role. (shrink)

There is an ongoing debate in philosophy of mind and epistemology about whether perceptual experience only represents those “thin” features of our environment that are apprehended by our senses, or whether, in addition to these, at least some perceptual experiences represent more complex, “thick” properties. My aim in this paper is to articulate an important difference between thin and thick properties, and thus to diagnose a key intuitive resistance many proponents of the thin view feel towards the thick (...) view. My diagnosis then provides us with a novel and compelling argument against the thick view. In what follows, first I consider two unsuccessful versions of an alternative strategy against the thick view found in the literature. Next, I present my own argument. The argument involves proposing two constraints on the phenomenal contents of perceptual experience, which I call the Presentation Principle and the Containment Principle, and then reasoning from these principles to a conclusion that is fatal to the thick view—an outcome that I call the problem of Phenomenal Explosion. I conclude by responding to several objections. (shrink)

This paper is about the epistemology of perceptual experiences that have enriched high-level content. Enriched high-level content is content about features other than shape, color, and spatial relations that has a particular etiology. Its etiology runs through states of the agent that process other perceptual content and output sensory content about high-level features. My main contention is that the justification provided by such experiences is not foundational justification. This is because the justification provided by such experiences is epistemically (...) dependent on having justification to believe certain claims about the content relevant for enrichment—claims about what I call the corresponding features.

According to a traditional Cartesian epistemology of perception, perception does not provide one with direct knowledge of the external world. Instead, your immediate perceptual evidence is limited to facts about your own visual experience, from which conclusions about the external world must be inferred. Cartesianism faces well-known skeptical challenges. But this chapter argues that any anti-Cartesian view strong enough to avoid these challenges must license a way of updating one’s beliefs in response to anticipated experiences that seems diachronically irrational. (...) To avoid this result, the anti-Cartesian must either license an unacceptable epistemic chauvinism, or else claim that merely reflecting on one’s experiences defeats perceptual justification. This leaves us with a puzzle: Although Cartesianism faces problems, avoiding them brings a new set of problems. (shrink)

We designed a new protocol requiring French adult participants to group a large number of Munsell colour chips into three or four groups. On one, relativist, view, participants would be expected to rely on their colour lexicon in such a task. In this framework, the resulting groups should be more similar to French colour categories than to other languages categories. On another, universalist, view, participants would be expected to rely on universal features of perception. In this second framework, the resulting (...) groups should match colour categories of three and four basic terms languages. In this work, we first collected data to build an accurate map of French colour terms categories. We went on testing how native French speakers spontaneously sorted a set of randomly presented coloured chips and, in line with the relativist prediction, we found that the resulting colour groups were more similar to French colour categories than to three and four basic terms languages. However, the same results were obtained in a verbal interference condition, suggesting that participants rely on language specific and nevertheless perceptual, colour categories. Collectively, these results suggest that the universalist/relativist dichotomy is a too narrow one. (shrink)

It is widely assumed that sense perception cannot deliver knowledge of nonactual (metaphysical) possibilities. We are not supposed to be able to know that a proposition p is necessary or that p is possible (if p is false) by sense perception. This paper aims to establish that the role of sense perception is not so limited. It argues that we can know lots of modal facts by perception. While the most straightforward examples concern possibility and contingency, others concern necessity and (...) impossibility. The possibility of a perceptual route to some modal knowledge is not as radical as it may at first sound. On the contrary, acknowledging it has benefits. (shrink)

Carter and Pritchard (2016) and Pritchard (2010, 2012, 2016) have tried to reconcile the intuition that perceptual knowledge requires only limited discriminatory abilities with the closure principle. To this end, they have introduced two theoretical innovations: a contrast between two ways of introducing error-possibilities and a distinction between discriminating and favoring evidence. I argue that their solution faces the “sufficiency problem”: it is unclear whether the evidence that is normally available to adult humans is sufficient to retain knowledge of (...) the entailing proposition and come to know the entailed proposition. I submit that, on either infallibilist or fallibilist views of evidence, Carter and Pritchard have set the bar for deductive knowledge too low. At the end, I offer an alternative solution. I suggest that the knowledge-retention condition of the closure principle is not satisfied in zebra-like scenarios. (shrink)

Theories of consciousness divide over whether perceptual consciousness is rich or sparse in specific representational content and whether it requires cognitive access. These two issues are often treated in tandem because of a shared assumption that the representational capacity of cognitive access is fairly limited. Recent research on working memory challenges this shared assumption. This paper argues that abandoning the assumption undermines post-cue-based “overflow” arguments, according to which perceptual conscious is rich and does not require cognitive access. Abandoning (...) it also dissociates the rich/sparse debate from the access question. The paper then explores attempts to reformulate overflow theses in ways that don’t require the assumption of limited capacity. Finally, it discusses the problem of relating seemingly non-probabilistic perceptual consciousness to the probabilistic representations posited by the models that challenge conceptions of cognitive access as capacity-limited.

Real-time computer graphics and complex sensory input challenge past assumptions of highly constrained metaphors based on static imagery. Access to research and gaming interfaces have popularized the understanding of tracking technologies that tailor interaction to ambulatory displacement and dexterous handling of objects, expanding the realm of metaphors from visual to physical phenomena. But behaviour and the mind have been studied far before there were real-time computer graphics or digitally created synthetic environments. Dynamic relationships between environment, body and thought are being (...) dissected today by neuro-scientific research, and, conversely, synthetic environments are being utilized to address psychological disorders. This article examines research on scientific and philosophical fields that advance the definition of representation, from an image-based realm as limited by previous popular media to an understanding of action and immersion, where attention is activated by change, and rooted in the body. From this perspective, the advent of embodied representation may not be as much of a change of medium, but the perceptual relation with the medium, the medium being a created Umwelt, where the virtual world builds the mind through the body.

The recent upsurge in “brain-training and perceptual-cognitive-training", proposing to improve isolated processes such as brain function, visual perception and decision-making, has created significant interest in elite sports practitioners, seeking to create an ‘edge’ for athletes. The claims of these related 'performance-enhancing industries' can be considered together as part of a process training approach proposing enhanced cognitive and perceptual skills and brain capacity, to support performance in everyday life activities, including sport. For example, the 'process-training industry' promotes the idea (...) that playing games not only makes you a better player, but also smarter, more alert, and a faster learner. In this position paper we critically evaluate the effectiveness of both types of process-training programmes in generalizing transfer to sport performance. These issues are addressed in three stages. First, we evaluate empirical evidence in support of perceptual-cognitive process training, and its application to enhancing sport performance. Second, we critically review putative modularised mechanisms underpinning this kind of training, addressing limitations and subsequent problems. Specifically, we consider merits of this highly specific form of training, which focuses on training of isolated processes such as cognitive processes (attention, memory, thinking) and visual perception processes, separately from performance behaviors and actions. We conclude that these approaches may, at best, may provide some 'general transfer' of underlying processes to specific sport environments, but lack 'specificity of transfer' to contextualize actual performance behaviors. A major weakness of process training methods is their focus on enhancing performance in body “modules” (e.g., eye, brain, memory, anticipatory sub-systems). What is lacking is evidence on how these isolated components are modified and subsequently interact with other process “modules”, which are considered to underlie sport performance. Finally, we propose how an ecological dynamics approach, aligned with an embodied framework of cognition undermines the rationale that modularised processes can enhance performance in competitive sport. An ecological dynamics perspective proposes that the body is a complex adaptive system, interacting with performance environments in a functionally integrated manner, emphasising that the inter-relation between motor processes, cognitive and perceptual functions and the constraints of a sport task is best understood at the performer-environment scale of analysis.

Algunos defensores del conceptualismo perceptual intentan bloquear el argumento noconceptualista de la riqueza de contenido afirmando que no hay percepción consciente sin atención. Para justificar esta afirmación los conceptualistas normalmente apelan a experimentos psicológicos, tales como la ceguera al cambio y la ceguera inatencional. En este artículo argumentaré que esta estrategia es insuficiente. Además sostendré, en base a recientes consideraciones teóricas y empíricas, que hay buenas razones para pensar que probablemente hay una forma de conciencia fenoménica visual más allá (...) de los límites de la atención que no es accesible cognitivamente y menos aún estructurada conceptualmente. Some supporters of perceptual conceptualism attempt to block the non-conceptualist argument from richness claiming that there is no conscious perception without attention. In order to justify this assertion conceptualists normally appeal to psychological experiments, such as change blindness and inattentional blindness. In this paper I will argue that this strategy is insufficient. In addition, I will point out, on the basis of recent theoretical and empirical considerations, that there are good reasons to think that probably there is a form of perceptual phenomenal consciousness beyond the limits of attention that is not cognitively accessible, not to mention conceptually structured.

There is a long-Standing tradition in philosophy that certain metaphysical theories of perceptual experience, if true, would lead to scepticism about the external world, whereas other theories, if true, would develop a non-sceptkal epistemology. I investigate these claims in the context of current metaphysical theories of sense-perception and argue that choice of perceptual ontology is of very limited help in developing a non-sceptical epistemology. Theorists who hold that perception is an intentional state have some advantage in explaining how (...) perceptual experiences serve as justifying reasons for empirical beliefs. Alston and others have argued that a successful defence of a contemporary version of naïve realism would secure further epistemological advantages. I argue that this is not the case. A complete explanation of experience's reason-giving power involves factors beyond the metaphysical nature of experience. (shrink)

Aron Gurwitsch claims that the field of consciousness is invariantly organized in a theme, thematic field, margin pattern. However, at least two perceptual presentations, chaos and boundlessness, are not ordered in accordance with this pattern. The question this study poses then is the following: given Gurwitsch's field-theory of experiential organization, what is the structure, status, and function of chaos and boundlessness in the field of consciousness? ;Using Gurwitsch's field-theory organization as a base, the structure of thematic chaos and then (...) of thematic boundlessness is articulated: the first by contrasting the field-theories of Gurwitsch and James, the second by contrasting Gurwitsch and Kant. It is concluded that in both cases no thematic Gestalt-coherence and no thematic field as relevant context is presented. ;In terms of status and function, chaos and boundlessness are interpreted as necessary limits. These "limit cases" are not "ideal limits" since they are possible perceptual presentations. Also, limit is taken to mean a two-edged presentation, one that is both an ending and a beginning. Interpreting Gurwitsch, we conclude that both cases are epistemological endings, since they represent a necessary end to the ordinary perception of things. Interpreting James, we conclude that it is possible that thematic chaos is also a metaphysical beginning in experience, since it is that experience in which reality is presented as underived and original. Interpreting Kant, we conclude that it is possible that boundlessness is also an ethical beginning in experience, since it is that experience in which the most original feeling of our sense of humanity is presented. ;We show that chaos and boundlessness each have their own unique field-organization, that they function as two-edged limits involving epistemological concerns on the one hand and metaphysical and ethical concerns respectively on the other, and that their structure and status as limits in the field of consciousness are not contingent but necessary.

One popular reason for rejecting moral realism is the lack of a plausible epistemology that explains how we come to know moral facts. Recently, a number of philosophers have insisted that it is possible to have moral knowledge in a very straightforward way—by perception. However, there is a significant objection to the possibility of moral perception: it does not seem that we could have a perceptual experience that represents a moral property, but a necessary condition for coming to know (...) that X is F by perception is the ability to have a perceptual experience that represents something as being F . Call this the ‘Representation Objection’ to moral perception. In this paper I argue that the Representation Objection to moral perception fails. Thus I offer a limited defense of moral perception.

This paper presents a framework for analysing perceptual Twin Earth thought experiments. Visual content normally has an analogue character, and it is argued in this paper that this sets certain constraints on the extent to which Twin Earth thought experiments can be successful. The argumentation in the paper is developed by using examples from visual spatial content. It is argued that visual spatial content can only be “twin-earthed” in a very limited way. Whereas the metrics of space can be (...) twin-earthed, visual experience has a structure that means that it can only be the vehicle for representing entities with geometrical structures. (shrink)

The present paradigm involved manipulating the congruency of the perceptual processing during the study and test phases of a recognition memory task. During each trial, a gaze-contingent window was used to limit the stimulus display to a region either inside or outside a 108 square centred on the participant’s point of gaze, constituting the Central and Peripheral viewing modes respectively. The window position changed in real time in concert with changes in gaze position. Four experiments documented better task performance (...) when viewing modes at encoding and retrieval matched than when they mismatched (i.e., perceptual specificity effects). Viewing mode congruency effects were demonstrated with both verbal and non-verbal stimuli. The present research is motivated and discussed in terms of theoretical views proposed in the 1970s including the levels-of-processing framework and the proceduralist viewpoint. In addition, implications for current processing and multiple systems views of memory are outlined. (shrink)

Dynamic, interactive sports require athletes to identify, pick-up and process relevant information in a very limited time, in order to then make an appropriate response. Perceptual-cognitive skills are, therefore, a key determinant of elite sporting performance. Recently, sport scientists have investigated ways to assess and train perceptual-cognitive skills, with one such method involving the use of blurred stimuli. Here, we describe the two main methods used to generate blur and then review the current findings in a sports context. (...) Overall, it has been shown the use of blur can enhance performance and learning of sporting tasks in novice participants, especially when the blur is applied to peripheral stimuli. However, while intermediate and expert level participants are relatively impervious to the presence of blur, it remains to be determined if they are positive effects on learning. In a final section, we describe some of the methodological issues that limit the application of blur and then discuss the potential use of virtual reality to extend the current research base in sporting contexts.

Christiansen & Chater propose that language comprehenders must immediately compress perceptual data by “chunking” them into higher-level categories. Effective language understanding, however, requires maintaining perceptual information long enough to integrate it with downstream cues. Indeed, recent results suggest comprehenders do this. Although cognitive systems are undoubtedly limited, frameworks that do not take into account the tasks that these systems evolved to solve risk missing important insights.

Perceptual performance, anticipating opponents' strategies, and judging chess positions especially in subliminal processing is related to expertise level and dependent on chunking processes. It becomes obvious that chess expertise is a multidimensional phenomenon related predominantly to experience. Under consideration of chess expertise categorization, we conducted two priming experiments expanding existing designs by gradually increasing the target and task complexity. The main aim was the evaluation of potential visuocognitive limitations. The results reveal experts' perceptual superiority manifested by their (...) faster reaction times in settings with increased stimulus and task complexity. Further, experts' priming effects seem to be affected by the target content and/ or priming duration. For short prime duration, experts show priming effects only for less complex prime-target content. Interestingly, for longer prime duration and more complex prime-target content, all participants reveal priming effects. In summary, we argue that experts' visuocognitive processing is rooted in a more efficient visuocognition due to stored chunks of checking and mating constellations. We suggest that visuocognitive limitations are related also to the prime-target complexity as well as to the task. Further investigations must be conducted in order to elucidate the factors with an increased impact on chess players' performance. (shrink)

A novel semantic naturalization program is proposed. Its three main differences from informational semantics approaches are as follows. First, it makes use of a perceptually based, four-factor interactive causal relation in place of a simple nomic covariance relation. Second, it does not attempt to globally naturalize all semantic concepts, but instead it appeals to a broadly realist interpretation of natural science, in which the concept of propositional truth is off-limits to naturalization attempts. And third, it treats all semantic concepts as (...) being purely abstract, so that concrete cognitive states are only indexed by them rather than instantiating them. (shrink)

In sport, perceptual skill training software is intended to assist tactical training in the field. The aim of this field study was to test whether ‘laboratory-based’ pattern recall training would augment tactical skill training performed on the field. Twenty-six soccer players between 14-16 years of age from a single team participated in this study and were divided into three groups. The first received field training on a specific tactical skill plus cognitive training sessions on the pattern recall task. The (...) second performed only the field training while the third group served as a control group and had field training on other topics. The task on the pre-, post- and retention tests was to recall specific soccer patterns displayed on a computer screen. Results showed significant changes between pre- to post-test performance. There was no significant interaction between groups and tests but the effect size was large. From pre- to retention-test, there was a significant difference between tests and an interaction between groups and tests, but no main effect difference between groups. On the basis of significance testing only retention was affected by the additional training, however, descriptive results and effect sizes from pre- to post-test were as expected and suggested there were learning benefits. Together these results indicate that augmented perceptual-cognitive training might be beneficial, but some limitations in our study design (e.g., missing field test, missing placebo group, etc.) need to be improved in future work.

This dissertation works out a new approach to understanding what makes a representation pictorial and what makes a representation imagistic. Over the last thirty years, the most common approach to these problems has been to claim that what makes a representation pictorial is that normal perceivers can perceive it in certain ways. By contrast, my approach singles out structural features of representational systems as that which distinguishes pictures from other kinds of representations. Pictorial systems are those that are transparent, relatively (...) syntactically sensitive, relatively replete, and semantically rich. All pictures are images, but the converse relation does not hold because images need not be transparent, though they satisfy the weaker condition of being mimetic. This approach is similar to, but enjoys advantages over, Nelson Goodman's work on the topic. ;The account of what makes a representation pictorial or imagistic is then brought to bear on the imagery debate, which concerns whether the brain implements imagistic systems of representation, specifically in the early stages of perception. A review of what we know about the workings of the visual and auditory systems reveals that no representations in the brain are pictorial, though some are imagistic in quite limited respects. Though they fail to be imagistic in many interesting respects, the early stages of the visual and auditory systems are highly isomorphic to what they represent. ;The role of isomorphism in perceptual states has been much discussed in both philosophy and cognitive neuroscience. The last two chapters of the dissertation argue that perceptual representations of traditionally secondary qualities like colors and sounds are isomorphic to those properties to a lesser degree than representations of traditionally primary qualities like shapes. This distinction in how such properties are represented can affect out intuitions concerning the nature of those properties and the nature of perceptual experience. Furthermore, it is argued that isomorphism is an important feature of perceptual representations because of the role it plays in making information cognitively available. This role for isomorphism is maintained even if one is an information theorist, and therefore thinks that lawful causal generalizations fix the content of representations. (shrink)

This paper demonstrates that the human visual system, the primary sensory conduit for primates, processes ambient energy in a way that obligatorily constructs the objects that we ineluctably perceive. And since our perceptual apparatus processes information only in terms of objects (along with the properties and movements of objects), we are limited in our ability to comprehend ‘what is’ when we move beyond our ordinary world of midsize objects—as, for example, when we address the micro microworld of quantum physics.

Let “phenomenal dogmatism” be the thesis that some experiences provide some beliefs with immediate justification, and do so purely in virtue of their phenomenal character. A basic question-mark looms over phenomenal dogmatism: Why should the fact that a person is visited by some phenomenal feel suggest the likely truth of a belief? In this paper, I press this challenge, arguing that perceptually justified beliefs are justified not purely by perceptual experiences’ phenomenology, but also because we have justified second-order background (...) beliefs to the effect that the occurrence of certain perceptual experiences is indicative of the likely truth of certain corresponding beliefs. To bring this out, I contrast “perceptual dogmatism” with “moral dogmatism”: the thesis that some emotional experiences provide some moral beliefs with immediate justification, and do so purely in virtue of their phenomenal character. I argue that moral dogmatism is much less antecedently appealing, precisely because the counterpart second-order beliefs here are much less plausible. (shrink)

Although our subjective impression is of a richly detailed visual world, numerous empirical results suggest that the amount of visual information observers can perceive and remember at any given moment is limited. How can our subjective impressions be reconciled with these objective observations? Here, we answer this question by arguing that, although we see more than the handful of objects, claimed by prominent models of visual attention and working memory, we still see far less than we think we do. Taken (...) together, we argue that these considerations resolve the apparent conflict between our subjective impressions and empirical data on visual capacity, while also illuminating the nature of the representations underlying perceptual experience.

Moral perception has made something of a comeback in recent work on moral epistemology. Many traditional objections to the view have been argued to fail upon closer inspection. But it remains an open question just how far moral perception might extend. In this paper, I provide the beginnings of an answer to this question by assessing the relationship between the metaphysical structure of different normative properties and a plausible constraint on which properties are eligible for perceptual awareness which I (...) call the Counterfactual Strengthening Test. Along the way I consider and reject a few other possible constraints on perceptual awareness. I defend the view that moral perception is restricted to the perception of evaluative and pro tanto deontic properties. I conclude with a few gestures toward what this limitation on moral perception may mean for broader moral epistemology. (shrink)

In an evolutionary perspective Louwerse elaborates the Symbol Interdependency Hypothesis (Louwerse, 2011), arguing that language has evolved such that it maps onto the perceptual system, allowing to bootstrap meaning also when grounding is limited. The author concludes that in principle the processing of abstract and concrete words is the same and that in both cases language users tend to rely anyway on indexical relationships that words entertain with other words.

: Thoreau's journal contains a number of passages which explore the nature of perception, developing a response to skeptical doubt. The world outside the human mind is real, and there is nothing illusory about its perceived beauty and meaning. In this essay, I draw upon the work of Stanley Cavell (among others) in order to frame Thoreau's reflections within the context of the skeptical questions he seeks to address. Value is not a subjective projection, but it also cannot be perceived (...) without the appropriate kind of emotional orientation or attunement toward the world: that is, an attitude of trust or acceptance. Without this affective receptivity, or "perceptual faith," our knowledge of reality is limited. The beliefs we hold onto in the face of objective uncertainty establish the framework within which we make particular evaluations, and in this sense they are a necessary condition of practical reason. Every understanding has its mood. (shrink)

David Abram’s The Spell of the Sensuous: Perception and Language in a More-Than-Human-World convincingly demonstrates the contribution that phenomenology, especially the work of Maurice Merleau-Ponty, can make to environmental theory. But Abram’s account suffers from several limitations that are explored here. First, although Abram intends to develop an “organic” account of thinking as grounded in the sensible world, his descriptions castigate reflection and reverse, rather than rethinking, the traditional hierarchy between mind and body. Second, Abram’s emphasis on perceptual (...) reciprocity as the basis for an environmental ethic underplays the importance of the symbolic level of our interaction with others. Merleau-Ponty’s later work, in particular his account of the reversibility of flesh, offers a fruitful alternative to Abram’s methodology. (shrink)

Enaction, as put forward by Varela and defended by other thinkers (notably Alva Noë, 2004; Susan Hurley, 2006; and Kevin O’Regan, 1992), departs from traditional accounts that treat mental processes (like perception, reasoning, and action) as discrete, independent processes that are causally related in a sequen- tial fashion. According to the main claim of the enactive approach, which Thompson seems to fully endorse, perceptual awareness is taken to be a skill-based activity. Our perceptual contact with the world, according (...) to the enactionists, is not mediated by representations but is enacted, and the notion of representation, belonging to the classic computational paradigm, has no place in this alternative approach. Though Thompson does not pronounce directly on the issue of representationalism, he is most definitely keeping the company of anti-representationalists, and in that context it is not unreasonable to take his silence for consent. In this paper, we will argue that the enactive approach to imagery is unworkable unless it makes appeal to representations, understood in a particular way. Not understood as pictures, to be sure. Or sentences for that matter. But those aren’t the only options. (shrink)

Using explicit memory measures, Cowan predicts a new circumstance in which the central capacity limit of 4 chunks should obtain. Supporting results for such an experiment, using continuous old-new recognition, are described. With implicit memory measures, Cowan assumes that short-term repetition priming reflects the central capacity limit. I argue that this phenomenon instead reflects limits within individual perceptual processing modules.

Hegel's discussion of the concept of “habit” appears at a crucial point in his Encyclopedia system, namely, in the transition from the topic of “nature” to the topic of “spirit” (Geist): it is through habit that the subject both distinguishes itself from its various sensory states as an absolute unity (the I) and, at the same time, preserves those sensory states as the content of sensory consciousness. By calling habit a “second nature,” Hegel highlights the fact that incipient spirit retains (...) a “moment” of the natural that marks a limitation compared to “pure thought” but that also makes perceptual consciousness possible. This makes Hegel's account analogous in important respects to John McDowell's “naturalism of second nature.” But Hegel's account of habit can be seen as a version of a Kantian synthesis of the productive imagination—and hence presupposes a given material that can become one's own by means of habit. This does not mean that Hegel falls into the Myth of the Given, but it does suggest that an appropriate account of second nature might be committed to something McDowell wants to deny: that nonconceptual states of consciousness play a role (even if not a justificatory role) in perception.

The method of phenomenal contrast aims to shed light on the phenomenal character of perceptual and cognitive experiences. Within the debate about cognitive phenomenology, phenomenal contrast arguments can be divided into two kinds. First, arguments based on actual cases that aim to provide the reader with a first-person experience of phenomenal contrast. Second, arguments that involve hypothetical cases and focus on the conceivability of contrast scenarios. Notably, in the light of these contrast cases, proponents and skeptics of cognitive phenomenology (...) remain steadfast in their views. I provide an explanation of the method’s dialectical ineffectiveness by focusing on first-person performances of phenomenal contrast tasks. In particular, I argue that introspective judgments about phenomenology are regimented by the view initially held. Understanding the underlying mechanisms responsible for the dialectical standoff in the face of phenomenal contrast cases casts light on introspection-based arguments for phenomenology in general. -/- https://www.cambridge.org/core/journals/journal-of-the-american-philosophical-association/article/on -the-limits-of-the-method-of-phenomenal-contrast/.

The thesis provides a new interpretation of Kant's claims for the epistemological significance of aesthetic judgment. I argue that the harmony of the imagination and the understanding in aesthetic judgment consists in a potentially unending activity of mental modeling, or "exhibiting," of figures corresponding to possible conceptual determinations of the perceptual form of a beautiful object. Since Kant holds just this capacity to exhibit concepts as figures in intuition to be a prerequisite to empirical conception, judgments of taste are (...) based on an activity underlying all cognition. ;I then turn to another area in which Kant claims a close connection between reflection and conception--his analysis of empirical concept formation and application. Kant states that we must presuppose a principle of reflective judgment in order to insure the discoverability of natural regularity. Kant recognizes that transcendental under-determines empirical law, but determining the extent to which Kant thinks this is true is of the utmost importance. Untempered, Kant's broad claims that the principle is necessary for the capacity to form and apply empirical concepts commits him to the un-Kantian position that a reflective principle is constitutive and not merely regulative. I find, however, that the principle is not required for the formation and application of any empirical concepts, but rather for those that purport to correspond to empirically real properties of things. ;Last, I place Kant's theory of reflection in a historical context, considering one Idealist criticism of it--that of Hegel in Faith and Knowledge. I argue that Hegel's Kant critique is best understood as an attempt to overturn the delicate balance Kant sought to strike in according a transcendentally necessary principle merely regulative status.

This paper explores the ways in which resource limitations influence the nature of perceptual and cognitive processes. A framework is developed that allows early visual processing to be analyzed in terms of these limitations. In this approach, there is no one ``best'' system for any visual process. Rather, a spectrum of systems exists, differing in the particular trade-offs made between performance and resource requirements.

The Body at the Limits of Representation. The Theory of the Body and Painting in Merleau-PontyIn Eye and Mind,” Merleau-Ponty quotes a phrase from Valéry: “the painter brings his body with him.” He interprets the corporeal experience of the artist, not only as the center of a perceptual orientation or kinesthesis, but also as the inspiration for poets and for painters. In this sense, one can place his theory of body not only within the problematic of the phenomenological constitution (...) of the perceived object, but also in the context of the deconstruction of representation or in the genealogy of “de-representation” (Lyotard). By following Merleau-Ponty’s interpretation of the works of Cézanne and Klee, we are going to see how his theory of the experience of body and the formation of their works of art meet up in his consideration of the reversibility of the visible and the invisible. When Merleau-Ponty quotes Valéry’s phrase “the painter brings his body with him,” the body of the artist is no longer “subject-body” perceiving the world in a prosaic way; rather, the body is implicated in the anonymous vision at the source from which the painter’s expression emerges. Just as nature is recounted through the poet, it has the faculty of seeing itself through the painter. In the “Methods of Natural Research,” Klee says “the resonance surpasses all the optical foundations between myself and that which opposes me,” “the united anti-optic way of the root going out of the earth, which looks at me from down below all the way up to my eyes” and of the “united non-optic way of the universe come from above.” He demonstrates that this non-optic resonance, rather than a mirror and a black screen separating the light, allows the eye to be seen as a point of junction of non-optical things and thereby it constitutes a part of the circle created by the new nature of works (eine neue Natürlichkeit des Werkes). Following what is particular to Merleau-Ponty’s thought in which the body is conceived as a principle of de-representation, one sees, by means of his intention of assessing modern artistic creation as the deconstruction of classical ontology, the overcoming of the ontology of the object. In conclusion, we note that the theory of body and of painting in Merleau-Ponty brings to light the limit of the possibility of representation in modern art, by emphasizing especially the non-perception or the transcendence that one can discern in the perceptual field. By interrogating the body of the painter and the poet, that is, the poetic body or the body as symbolism, prior to its being diverted into being a result of the brain and of the libido where the body is no longer the body visible in the world, by doing this, Merleau-Ponty has found a way of placing the body beyond representation. Poièsis is no longer mimèsis in the banal sense of imitation, and the poetic body is not the representational body. But, he has found a way of placing it still in Visibility, as if there were a hinge in this border between the visible and the invisible, in this border between representation and de-representation, a border that one cannot definitively overcome by structuring it as a dichotomy. (De-representation, but the visible. Therefore the possibility of visible de-representation in the artistic creation, in poièsis.) This hinge, which denies us an alternation, is the body, the flesh, which is the condition of thought as ontological interrogation: an ontological interrogation in the age of ir-representation, in the age of the impossibility of representation (Vorstellung) and of poem (Dichtung), in the age of crowds where the image appears as one of my fellow creatures just like the shadow cast by existence.Il corpo ai limiti della rappresentazione. La teoria del corpo e della pittura di Merleau-PontyNe L’occhio e lo spirito Merleau-Ponty cita una frase di Valéry: “il pittore si dà con il suo corpo”. Egli interpreta l’esperienza corporea dell’artista non solo come il centro di un orientamento percettivo o cinestesico, ma anche come motivo d’ispirazione per poeti e per pittori. In questo senso, si può collocare la sua teoria del corpo non solo all’interno della problematica della costituzione fenomenologica dell’oggetto percepito, ma anche nel contesto della decostruzione della rappresentazione o nella genealogia della “derappresentazione” (Lyotard). Seguendo l’interpretazione merleaupontiana delle opere di Cézanne e di Klee, vedremo come la sua teoria dell’esperienza del corpo e la formazione delle loro opere d’arte convergano nella considerazione della reversibilità del visibilee dell’invisibile. Quando Merleau-Ponty cita la frase di Valéry “il pittore si dà con il suo corpo”, il corpo dell’artista non è più un corpo soggettivo che percepisce il mondo in modo prosaico; il corpo è piuttosto implicato nella visione anonima dell’origine dalla quale emerge l’espressione del pittore. In Wege des Naturstudiums, Klee afferma che “la risonanza sorpassa tutti i fondamenti ottici tra me e ciò che mi si oppone”. Egli dimostra che questa risonanza non-ottica, piuttosto che essere uno specchio o uno schermo nero che separa la luce, permette di vedere l’occhio come un punto di giunzione di cose non ottiche e ciò costituisce una parte del circolo creato dalla nuova natura delle opere (eine neue Natürlichkeit des Werkes). Seguendo la particolarità del pensiero merleaupontiano, secondo il quale il corpo è concepito come un principio di de-rappresentazione, si nota, in virtù della sua intenzione di interpretare la creazione nell’arte moderna come la decostruzione dell’ontologia classica, il superamento dell’ontologia oggettivistica. In conclusione, osserviamo come la teoria del corpo e della pittura di Merleau-Ponty chiarisca i limiti della possibilità della rappresentazione nell’arte moderna, enfatizzando l’impercezione o la trascendenza che si può distinguere nel campo percettivo. Interrogando il corpo del pittore e del poeta – il corpo poetico o il corpo come simbolismo, a monte del suo porsi come risultato della mente o della libido, là dove il corpo non è ancora corpo visibile nel mondo – Merleau-Ponty ha trovato il mondo di collocare il corpo al di là della rappresentazione. Poièsis non è più mimesis nel senso banale d’imitazione, e il corpo poetico non è il corpo rappresentativo. Egli ha trovato il modo di posizionare il corpo nella Visibilità, come se esistesse un punto di rovesciamento situato sul confi ne tra visibile ed invisibile, ovvero sul confine tra rappresentazione e de-rappresentazione: un confine che non si può definitivamente superare se lo si continua a strutturare come dicotomia. Questo punto, che ci nega un’alternativa, è il corpo, la carne, che è condizione del pensiero come interrogazione ontologica: un’interrogazione ontologica nell’era dell’ir-rappresentazione, nell’era dell’impossibilità di rappresentare (Vorstellung) o di creare poemi (Dichtung), nell’era delle masse, in cui l’immagine appare come uno dei miei simili, come l’ombra proiettata dall’esistenza.

In this compendium of essays, some of the world's leading thinkers discuss their conceptions of space and time, as viewed through the lens of their own discipline. With an epilogue on the limits of human understanding, this volume hosts contributions from six or more diverse fields. It presumes only rudimentary background knowledge on the part of the reader. Time and again, through the prism of intellect, humans have tried to diffract reality into various distinct, yet seamless, atomic, yet holistic, independent, (...) yet interrelated disciplines and have attempted to study it contextually. Philosophers debate the paradoxes, or engage in meditations, dialogues and reflections on the content and nature of space and time. Physicists, too, have been trying to mold space and time to fit their notions concerning micro- and macro-worlds. Mathematicians focus on the abstract aspects of space, time and measurement. While cognitive scientists ponder over the perceptual and experiential facets of our consciousness of space and time, computer scientists theoretically and practically try to optimize the space-time complexities in storing and retrieving data/information. The list is never-ending. Linguists, logicians, artists, evolutionary biologists, geographers et cetera, all are trying to weave a web of understanding around the same duo. However, our endeavour into a world of such endless imagination is restrained by intellectual dilemmas such as: Can humans comprehend everything? Are there any limits? Can finite thought fathom infinity? We have sought far and wide among the best minds to furnish articles that provide an overview of the above topics. We hope that, through this journey, a symphony of patterns and tapestry of intuitions will emerge, providing the reader with insights into the questions: What is Space? What is Time?

Some theorists hold that the human perceptual system has a component that receives input only from units lower in the perceptual hierarchy. This thesis, that we shall here refer to as the encapsulation thesis, has been at the center of a continuing debate for the past few decades. Those who deny the encapsulation thesis often rely on the large body of psychological findings that allegedly suggest that perception is influenced by factors such as the beliefs, desires, goals, and (...) the expectations of the perceiver. Proponents of the encapsulation thesis, however, often argue that, when correctly interpreted, these psychological findings are compatible with the thesis. In our view, the debate over the significance and the correct interpretation of these psychological findings has reached an impasse. We hold that this impasse is due to the methodological limitations over psychophysical experiments, and it is very unlikely that such experiments, on their own, could yield results that would settle the debate. After defending this claim, we argue that integrating data from cognitive neuroscience resolves the debate in favor of those who deny the encapsulation thesis. (shrink)

In this article I deal with the notion of observation, from a phenomenologically motivated point of view, and its representation mainly by means of the formal language of quantum mechanics. In doing so, I have taken the notion of observation in two diverse contexts. In one context as a notion related with objects of a logical-mathematical theory taken as registered facts of phenomenological perception ( Wahrnehmung ) inasmuch as this phenomenological idea can also be linked with a process of measurement (...) on the quantum-mechanical level. In another context I have taken it as connected with a notion of temporal constitution basically as it is described in E. Husserl’s texts on the phenomenology of temporal consciousness. Given that mathematical objects as formal-ontological objects can be thought of as abstractions of perceptual objects by means of categorial intuition, the question is whether and under what theoretical assumptions we can, in principle, include quantum objects in abstraction in the class of formal-ontological objects and thus inquire on the limits of their description within a formal-axiomatical theory. On the one hand, I derive an irreducibility on the level of individuals taken in formal representation as syntactical atoms-substrates without any further content and on the other hand a transcendental subjectivity of consciousness objectified as a self-constituted temporal unity upon which it is ultimately grounded the possibility of generation of an abstract predicative universe of discourse.
