Central to contemporary cognitive science is the notion that mental processes involve computations defined over internal representations. This view stands in sharp contrast to the to visual perception and cognition, whose most prominent proponent has been J.J. Gibson. In the direct theory, perception does not involve computations of any sort; it is the result of the direct pickup of available information. The publication of Gibson's recent book (Gibson 1979) offers an opportunity to examine his approach, and, more generally, (...) to contrast the theory of direct perception with the computational/representational view. In the first part of the present article (Sections 2direct perceptioncase study”: the problem of perceiving the three-dimensional shape of moving objects is examined. This problem, which has been extensively studied within the immediate perception framework, serves to illustrate some of the inherent shortcomings of that approach. Finally, in Section 5, an attempt is made to place the theory of direct perception in perspective by embedding it in a more comprehensive framework. (shrink)

Studies of the conceptual abilities of nonhuman primates demonstrate the substantial range of these abilities as well as their limitations. Such abilities range from categorization on the basis of shared physical attributes, associative relations and functions to abstract concepts as reflected in analogical reasoning about relations between relations. The pattern of results from these studies point to a fundamental distinction between monkeys and apes in both their implicit and explicit conceptual capacities. Monkeys, but not apes, might be best regarded as (...) “paleo‐logicans” in the sense that they form common class concepts of identity on the basis of identical predicates (i.e., shared features). The discrimination of presumably more abstract relations commonly involves relatively simple procedural strategies mediated by associative processes likely shared by all mammals. There is no evidence that monkeys can perceive, let alone judge, relations‐between‐relations. This analogical conceptual capacity is found only in chimpanzees and humans. Interestingly, the “analogical ape,” like the child, can make its analogical knowledge explicit only if it is first provided with a symbol system by which propositional representations can be encoded and manipulated.

Husserl famously argues that it is essential to perception to present the perceived object in perspectives. Hence, there is no – and there cannot be – perception without perspectival givenness. Yet, it seems that there are counterexamples to this essentialist claim, for we seem to be able to imagine beings that do not perceive in perspectives. Recently, there have been some accounts in the literature that critically discuss those counterexamples and assess to what extent they succeed in challenging (...) Husserl’s essentialist claim. In this paper I discuss three different answers to these counterexamples, all of them are found wanting. I offer a novel solution, taking into account some crucial findings of the contemporary debate about imagination and modality. I argue that this new solution is capable of fully vindicating Husserl’s essentialist claim. Finally, I reconstruct Husserl’s own way to treat such counterexamples, in order to showcase the notion of modality Husserlian phenomenology relies on. I argue for the hitherto widely underappreciated point that Husserl’s transcendental phenomenology cannot appeal to strictly absolute modality but that the kind of modality in Husserlian phenomenology is conditional on the facticity that we have the transcendental structure we do in fact have.

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

Music can be described as sequences of events that are structured in pitch and time. Studying music processing provides insight into how complex event sequences are learned, perceived, and represented by the brain. Given the temporal nature of sound, expectations, structural integration, and cognitive sequencing are central in music perception (i.e., which sounds are most likely to come next and at what moment should they occur?). This paper focuses on similarities in music and language cognition research, showing that music (...) cognition research provides insight into the understanding of not only music processing but also language processing and the processing of other structured stimuli. The hypothesis of shared resources between music and language processing and of domain-general dynamic attention has motivated the development of research to test music as a means to stimulate sensory, cognitive, and motor processes.

Diderot s’est passionné toute sa vie pour les questions musicales. C’est à travers elles que cet article traite du thème de la « perception des rapports » dans l’esthétique diderotienne. Le trait saillant des « Principes généraux d’acoustique » (1748) est le refus de distinguer un point de vue strictement scientifique et esthétiquement neutre, et un point de vue proprement esthétique. Dans les pas du Descartes de l’Abrégé de musique, et dans une discussion serrée avec le père André, Diderot (...) soutient une thèse que l’on pourrait qualifier d’empirico-malebranchienne. Si, sur le modèle de l’optique cartésienne, Diderot soutient que l’oreille perçoit les consonances et le beau musical selon une sorte de trigonométrie naturelle, il refuse de l’appuyer sur l’action directe d’une puissance supérieure à l’esprit, comme chez l’auteur de De la recherche de la vérité. La « perception des rapports » est au contraire fondée sur une conception empiriste du nombre : c’est dans l’expérience du dénombrement, et par le biais des sens, que nous connaissons le nombre. La conception des « corps harmoniques », développée dans la « Lettre à Mlle *** », permet d’associer la réalité des rapports des nombres, leur rationalité et le plaisir des corps – sans faire appel à une raison universelle sur le modèle malebranchien.

The current debates dealing with empathy, social cognition, and the problem of other minds widely accept the assumption that, whereas we can directly perceive the other’s body, certain additional mental operations are needed in order to access the contents of the other’s mind. Body-perception has, in other words, been understood as something that merely mediates our experience of other minds and requires no philosophical analysis in itself. The available accounts have accordingly seen their main task as pinpointing the operations (...) and mechanisms that enable us to move beyond body-perception—and here acts such as inference, simulation, and projection have usually been the main candidates. This whole setting, however, seems to rely on a somewhat Cartesian assumption, according to which body-perception fundamentally amounts to the perception of a material thing, res extensa, starting from which we then strive to grasp the other as a res cogitans. Insofar as one begins with the question of how we can discover and understand mindedness in things that cannot be directly perceived as minded, the Cartesian setting is already taken for granted—and this is, in fact, exactly what most of the available proposals seem to be doing. From a phenomenological point of view, the Cartesian setting is untenable and seriously misleads the whole debate. The present article reassesses the role and status of body-perception in empathy. Making use of the Husserlian theory of expressivity in particular, the article engages a phenomenological framework of analysis, challenges the above-mentioned assumption concerning the nature of body-perception, and argues for the immediate nature of empathy.

Background: Today, healthcare organizations are challenged to retain nurses’ generation and to maintain justice that is a predictor of nurses’ behaviors in their work environment. Acquiring knowledge about the level of organizational justice and workplace deviance could help in identifying factors amenable for change that can make a difference in enhancing nurses’ dedication and loyalty to their organizations. Aim: The aim of this study was to investigate nurses’ perception of organisational justice and workplace deviance in their hospital, and to (...) determine the relationship between perceived organisational justice and workplace deviance. Methods: A cross-sectional design was used with a convenient sample of all nurses (N = 400) who were working in inpatient care units at two Egyptian hospitals affiliated to the university and private health sectors in Alexandria governorate, Egypt. Organisational justice and workplace deviance questionnaires proved valid and reliable to measure studied variables. Descriptive analysis, Student’s t-test, Pearson correlation (r), and regression analysis (R2) were used for statistical analysis. Ethical considerations: This study was approved by the Ethics Committee at the Faculty of Nursing, Alexandria University. Informed consent, information confidentiality, and voluntary participation were guaranteed. Results: This study showed that overall nurses’ perceptions of organisational justice and workplace deviance are lower than the average. Organisational justice significantly related negatively to workplace deviance (r = −0.152, p = 0.002) and organisational justice as an independent variable contributed a significant predictive power of workplace deviance (R2 = 0.023). Conclusions: This study highlighted important implications for hospital and nurse managers to create and maintain a healthy and supportive work environment that promotes organisational justice and decreases workplace deviance. To achieve this, a culture of respectful communication, justice in policies, and a proper procedure for allocating resources, workload, and rewards systems is a must. Educational interventions to increase nurses’ awareness of workplace deviance and its potential consequences and coping strategies are imperative for the health of the nursing profession. (shrink)

Visual conscious perception could be grounded in a nonconscious sensorimotor domain. Although invisible, information can be processed up to the level of response activation. Moreover, these nonconscious processes are modified by actual intentions. This notion bridges a gap in the theoretical framework of O'Regan & Noë.

Atypical sensorimotor developmental trajectories greatly contribute to the profound heterogeneity that characterizes Autism Spectrum Disorders. Individuals with ASD manifest deviations in sensorimotor processing with early markers in the use of sensory information coming from both the external world and the body, as well as motor difficulties. The cascading effect of these impairments on the later development of higher-order abilities underlines the need for interventions that focus on the remediation of sensorimotor integration skills. One of the promising technologies for such stimulation (...) is Immersive Virtual Reality. In particular, head-mounted displays have unique features that fully immerse the user in virtual realities which disintegrate and otherwise manipulate multimodal information. The contribution of each individual sensory input and of multisensory integration to perception and motion can be evaluated and addressed according to a user’s clinical needs. HMDs can therefore be used to create virtual environments aimed at improving people’s sensorimotor functioning, with strong potential for individualization for users. Here we provide a narrative review of the sensorimotor atypicalities evidenced by children and adults with ASD, alongside some specific relevant features of IVR technology. We discuss how individuals with ASD may interact differently with IVR versus real environments on the basis of their specific atypical sensorimotor profiles and describe the unique potential of HMD-delivered immersive virtual environments to this end.

This is a survey of the development of the philosophy of perception over the past twelve years. There are four sections. Part I deals largely with arguments for the propositionalizing of perception and for those types of externally founded realism that eschew inner representation. Part ii is devoted to three books that put the case for sense-Data (pennycuick, Jackson, Ginet) and some of the arguments against (pitcher). Part iii outlines james j gibson's psychological theory. Part iv takes up (...) the arguments for a theory of 'dual coding', Combining a non-Epistemic inner presentation as a first stage with epistemic selection as an independent module. The mental-Image argument (kosslyn, Pylyshyn) and wittgenstein's remarks on psychology, Recently published, Are brought in as relevant to this issue. (edited). (shrink)

This is a much shorter version of our entry on the Epistemology of Perception, which will be published in the Oxford Handbook for the Philosophy of Perception in 2013. The longer version has far more references in it, whereas this version is pared down to the essentials.

Robin Le Poidevin (2007) claims that we do form perceptual beliefs regarding order and duration based on our perception of events, but neither order nor duration are by themselves objects of perception. Temporal properties are discernible only when one first perceives their bearers, and temporal relations are discernible only when one first perceives their relata. The epistemic issue remains as to whether or not our perceptual beliefs about order and duration are formed on the causal basis of an (...) event’s objective order and duration. Le Poidevin raises this issue in the form of an epistemological puzzle of time perception, from which he derives the claim that the order and duration of events do not causally contribute to our perceptual beliefs about them. Since his view is motivated by a causal truthmaker principle for grounding knowledge, it also holds that perceptual beliefs about temporal features must be caused by the features themselves in order to count as knowledge. Given these theoretical commitments, there is a puzzle concerning how such perceptual beliefs could constitute knowledge of temporal properties. In response to Le Poidevin, I argue for an account according to which order and duration are objects of perception, causally contribute to our perceptual beliefs about them, and such beliefs are capable of counting as knowledge. I conclude by showing that, on my alternative account, the epistemological puzzle dissolves and his own solution to it fails. (shrink)

The aim of the analyzes carried out in this paper is to show that within the multitude of theories of perception which center their main presuppositions around the idea of action and embodiment, we can distinguish a body of approaches, which characteristically emphasize the following claims: that it is the living organism that should serve as perceiving subject; that perceptual states are not only a form of action but primarily a form of consciousness; that perceptual information is obtained by (...) perceiving subjects from the environment by means of so-called perceptual invariants.

Prvním cílem předkládané studie je podat podrobnější výklad pojetí smyslového vnímání v rukopisech Jana Patočky z let 1939–1945. Druhým cílem je ukázat originální i šířeji sdílenou stránku Patočkova pojetí na základě jeho srovnání s analogickými tezemi formulovanými v přednáškách Maurice Merleau-Pontyho z roku 1953. – Východiskem Patočkovy koncepce smyslového vnímání je myšlenka předmětné a horizontové intencionality. Jejím účelem je toto pojetí intencionality deskriptivně založit a interpretativně rozvinout tak, aby umožnilo pochopit vztah a distanci prožívajícího a prožívaného. Za tímto účelem Patočka (...) koncipuje pojem bytostného zájmu jednotlivého bytí o toto bytí samo jakožto princip předmětné intencionality a počátek individuální sebeobjektivace, jíž je tělo. Vztah mezi tímto zájmem, tělem a předmětnou intencí popisuje jako poměr výrazu a vyjádření. Na základě této deskripce předkládá fenomenologickou interpretaci veškeré předmětnosti jakožto výrazu určitého života na jedné straně a intencionálního vyjádření na straně druhé. – Právě tento závěr se ve srovnání s tezemi Merleau-Pontyho ukazuje jako originální myšlenka Patočkova filosofického fragmentu.
