  3. Egocentric Spatial Representation in Action and Perception.Robert Briscoe - 2009 - Philosophy and Phenomenological Research 79 (2):423-460.
    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 (...)

  4. Visual Spatial Constancy and Modularity: Does Intention Penetrate Vision?Wayne Wu - 2013 - Philosophical Studies 165 (2):647-669.
    Is vision informationally encapsulated from cognition or is it cognitively penetrated? I shall argue that intentions penetrate vision in the experience of visual spatial constancy: the world appears to be spatially stable despite our frequent eye movements. I explicate the nature of this experience and critically examine and extend current neurobiological accounts of spatial constancy, emphasizing the central role of motor signals in computing such constancy. I then provide a stringent condition for failure of informational encapsulation that (...)

    Nonlinear Effects of Spatial Connectedness Implicate Hierarchically Structured Representations in Visual Working Memory.Błażej Skrzypulec & Adam Chuderski - 2020 - Journal of Memory and Language 113:104124.
    Five experiments investigated the role of spatial connectedness between a pair of objects presented in the change detection task for the actual capacity of visual working memory (VWM) in healthy young adults (total N = 405). Three experiments yielded a surprising nonlinear relationship between the proportion of pair-wise connected objects and capacity, with the highest capacity observed for homogenous displays, when either all objects were connected or disjointed. A drop in capacity, ranging from an average of a quarter (...)

  9. Representation and Constraints: The Inverse Problem and the Structure of Visual Space.Gary Hatfield - 2003 - Acta Psychologica 114:355-378.
    Visual space can be distinguished from physical space. The first is found in visual experience, while the second is defined independently of perception. Theorists have wondered about the relation between the two. Some investigators have concluded that visual space is non-Euclidean, and that it does not have a single metric structure. Here it is argued that visual space exhibits contraction in all three dimensions with increasing distance from the observer, that experienced features of this contraction are (...)

    Connecting Internal and External Representations: Spatial Transformations of Scientific Visualizations. [REVIEW]J. Gregory Trafton, Susan B. Trickett & Farilee E. Mintz - 2005 - Foundations of Science 10 (1):89-106.
    Many scientific discoveries have depended on external diagrams or visualizations. Many scientists also report to use an internal mental representation or mental imagery to help them solve problems and reason. How do scientists connect these internal and external representations? We examined working scientists as they worked on external scientific visualizations. We coded the number and type of spatial transformations (mental operations that scientists used on internal or external representations or images) and found that there were a very (...)

    Spatial Distortion Induced by Imperceptible Visual Stimuli.Ricky Kc Au, Fuminori Ono & Katsumi Watanabe - 2013 - Consciousness and Cognition 22 (1):99.
    Previous studies have explored the effects of attention on spatial representation. Specifically, in the attentional repulsion effect, a transient visual cue that captures attention has been shown to alter the perceived position of a target stimulus to the direction away from the cue. The effect is also susceptible to retrospective influence, that attention appears to attract the target when the cue appears afterwards. This study examined the necessity of visual awareness of the cue in these phenomena. We (...)

  13. Spatial Memory and Blindness: The Role of Visual Loss on the Exploration and Memorization of Spatialized Sounds.Walter Setti, Luigi F. Cuturi, Elena Cocchi & Monica Gori - 2022 - Frontiers in Psychology 13.
    Spatial memory relies on encoding, storing, and retrieval of knowledge about objects’ positions in their surrounding environment. Blind people have to rely on sensory modalities other than vision to memorize items that are spatially displaced, however, to date, very little is known about the influence of early visual deprivation on a person’s ability to remember and process sound locations. To fill this gap, we tested sighted and congenitally blind adults and adolescents in an audio-spatial memory task inspired (...)

    Separate Visual Representations in the Planning and Control of Action.Scott Glover - 2004 - Behavioral and Brain Sciences 27 (1):3-24.
    Evidence for a dichotomy between the planning of an action and its on-line control in humans is reviewed. This evidence suggests that planning and control each serve a specialized purpose utilizing distinct visual representations. Evidence from behavioral studies suggests that planning is influenced by a large array of visual and cognitive information, whereas control is influenced solely by the spatial characteristics of the target, including such things as its size, shape, orientation, and so forth. Evidence from (...)

    The on-going debate over the ‘admissible contents of perceptual experience’ concerns the range of properties that human beings are directly acquainted with in perceptual experience. Regarding vision, it is relatively uncontroversial that the following properties can figure in the contents of visual experience: colour, shape, illumination, spatial relations, motion, and texture. The controversy begins when we ask whether any properties besides these figure in visual experience. We argue that ‘ensemble properties’ should be added to the list of (...)

    Visual Perception and the Emergence of Minimal Representation.Argyris Arnellos & Alvaro Moreno - 2021 - Frontiers in Psychology 12.
    There is a long-lasting quest of demarcating a minimally representational behavior. Based on neurophysiologically-informed behavioral studies, we argue in detail that one of the simplest cases of organismic behavior based on low-resolution spatial vision–the visually-guided obstacle avoidance in the cubozoan medusa Tripedalia cystophora–implies already a minimal form of representation. We further argue that the characteristics and properties of this form of constancy-employing structural representation distinguish it substantially from putative representational states associated with mere sensory indicators, and we reply to (...)

    Social Beliefs and Visual Attention: How the Social Relevance of a Cue Influences Spatial Orienting.Matthias S. Gobel, Miles R. A. Tufft & Daniel C. Richardson - 2018 - Cognitive Science 42 (S1):161-185.
    We are highly tuned to each other's visual attention. Perceiving the eye or hand movements of another person can influence the timing of a saccade or the reach of our own. However, the explanation for such spatial orienting in interpersonal contexts remains disputed. Is it due to the social appearance of the cue—a hand or an eye—or due to its social relevance—a cue that is connected to another person with attentional and intentional states? We developed an interpersonal version (...)

    The posterior parietal cortex and frontal eye field contain maps of visual salience on which the decision to choose a saccade may be based. However, an averaging express saccade is not represented by a victorious unimodal representation in the superior colliculus. Normalization as described by Findlay & Walker is not necessary for the generation of saccades.

  20. The Role of Visual Indexes in Spatial Vision and Imagery∗∗.Zenon Pylyshyn - unknown
    This paper describes a programmatic theory of a process in early vision called indexing. The theory hypothesizes that a small number of primitive indexes are available for individuating, tracking and providing direct access to salient visual objects. We discuss some empirical and theoretical arguments in favor of the proposed index as a resource-limited link between an internal visual representation and objects in the visual world. We argue that this link is needed to explain a large range of (...)

    The public transport sector in the urban landscape in Nigeria is a prominent social site for the spatial distribution of automobile graffiti signatures. Transporters have various kinds of symbolic tags on their vehicles that convey different messages which represent their local attitudes, beliefs, religious identities, folk psychology, and safety precautionary measures to recipients (other road users and passers-by). This article, based on two case studies, examines the practice of automobile graffiti on trucks and lorries in Calabar metropolis, Cross River (...)

    Exploring the Functional Advantages of Spatial and Visual Cognition From an Architectural Perspective.Scott D. Lathrop, Samuel Wintermute & John E. Laird - 2011 - Topics in Cognitive Science 3 (4):796-818.
    We present a general cognitive architecture that tightly integrates symbolic, spatial, and visual representations. A key means to achieving this integration is allowing cognition to move freely between these modes, using mental imagery. The specific components and their integration are motivated by results from psychology, as well as the need for developing a functional and efficient implementation. We discuss functional benefits that result from the combination of multiple content-based representations and the specialized processing units associated with (...)

    According to “actionism” (Noë 2010), perception constitutively depends on implicit knowledge of the way sensory stimulations vary as a consequence of the perceiver’s self-movement. My aim in this contribution is to develop an alternative conception of the role of action in perception present in the work of Gareth Evans using resources provided by Ruth Millikan’s biosemantic theory of mental representation.

    The importance of working memory in reading and mathematics performance has been widely studied, with recent research examining the components of WM and their roles in these educational outcomes. However, the differing relationships between these abilities and the foundational skills involved in the development of reading and mathematics have received less attention. Additionally, the separation of verbal, visual and spatial storage and processing and subsequent links with foundational skills and downstream reading and mathematics has not been widely examined.

    Towards Structural Systematicity in Distributed, Statically Bound Visual Representations.Shimon Edelman & Nathan Intrator - 2003 - Cognitive Science 23 (1):73-110.
    The problem of representing the spatial structure of images, which arises in visual object processing, is commonly described using terminology borrowed from propositional theories of cognition, notably, the concept of compositionality. The classical propositional stance mandates representations composed of symbols, which stand for atomic or composite entities and enter into arbitrarily nested relationships. We argue that the main desiderata of a representational system — productivity and systematicity — can (indeed, for a number of reasons, should) be achieved (...)

    Reconstructing Neural Representations of Tactile Space.Luigi Tamè, Raffaele Tucciarelli, Renata Sadibolova, Martin I. Sereno & Matthew R. Longo - 2021 - NeuroImage 229.
    Psychophysical experiments have demonstrated large and highly systematic perceptual distortions of tactile space. Such a space can be referred to our experience of the spatial organisation of objects, at representational level, through touch, in analogy with the familiar concept of visual space. We investigated the neural basis of tactile space by analysing activity patterns induced by tactile stimulation of nine points on a 3 × 3 square grid on the hand dorsum using functional magnetic resonance imaging. We used (...)

    Spatial Facilitation by Color and Luminance Edges: Boundary, Surface, and Attentional Factors.Birgitta Dresp & Stephen Grossberg - 1995 - Vision Research 39 (20):3431-3443.
    The thresholds of human observers detecting line targets improve significantly when the targets are presented in a spatial context of collinear inducing stimuli. This phenomenon is referred to as spatial facilitation, and may reflect the output of long-range interactions between cortical feature detectors. Spatial facilitation has thus far been observed with luminance-defined, achromatic stimuli on achromatic backgrounds. This study compares spatial facilitation with line targets and collinear, edge-like inducers defined by luminance contrast to spatial facilitation (...)

    In the final scene of Michel Tournier’s postcolonial novel La Goutte d’or, the protagonist, Idriss, shatters the glass of a Cristobal & Co. storefront window while operating a jackhammer in the working-class Parisian neighbourhood on the Rue de la Goutte d’or. Glass fragments fly everywhere as the Parisian police arrive. In La Goutte d’or, Tournier explores the identity construction of Idriss through a discussion of the role that visual images play in the development of a twentieth-century consciousness of the (...)

    Using a novel enumeration task, we examined the encoding of spatial information during subitizing. Observers were shown masked presentations of randomly-placed discs on a screen and were required to mark the perceived locations of these discs on a subsequent blank screen. This provided a measure of recall for object locations and an indirect measure of display numerosity. Observers were tested on three stimulus durations and eight numerosities. Enumeration performance was high for displays containing up to six discs—a higher subitizing (...)

    Despite the subjective experience of a continuous and coherent external world, we will argue that the perception and categorisation of visual space is constrained by the spatial resolution of the sensory systems but also and above all, by the pre-reflective representations of the body in action. Recent empirical data in cognitive neurosciences will be presented that suggest that multidimensional categorisation of perceptual space depends on body representations at both an experiential and a functional level. Results will (...)

    This somewhat odd paper argues against a representational view of visual experience using an intricate "inversion" type thought experiment involving double vision: two subjects could represent external space in the same way while differing phenomenally due to different "spread" in their double images. The spatial structure of the visual field is explained not by representation of external space but functionally, in terms of the possible locations of an attentional spotlight. -/- I'm fond of the ideas in this (...)

    Visual Attention in Pictorial Perception.Gabriele Ferretti & Francesco Marchi - 2020 - Synthese 199 (1-2):2077-2101.
    According to the received view in the philosophical literature on pictorial perception, when perceiving an object in a picture, we perceive both the picture’s surface and the depicted object, but the surface is only unconsciously represented. Furthermore, it is suggested, such unconscious representation does not need attention. This poses a crucial problem, as empirical research on visual attention shows that there can hardly be any visual representation, conscious or unconscious, without attention. Secondly, according to such a received view, (...)

  34. Unsupervised Learning of Visual Structure.Shimon Edelman - unknown
    To learn a visual code in an unsupervised manner, one may attempt to capture those features of the stimulus set that would contribute significantly to a statistically efficient representation. Paradoxically, all the candidate features in this approach need to be known before statistics over them can be computed. This paradox may be circumvented by confining the repertoire of candidate features to actual scene fragments, which resemble the “what+where” receptive fields found in the ventral visual stream in primates.

    In this chapter, Pautz raises a puzzle about spatial experience for phenomenal internalists like Ned Block. If an accidental, lifelong brain-in-the-void (BIV) should have all the same experiences as you, it would have an experience as of items having various shapes, and be able to acquire concepts of those shapes, despite being cut off from real things with the shapes. Internalists cannot explain this by saying that BIV is presented with Peacocke-style visual field regions having various shapes, because (...)

    The emulation theory of representation is developed and explored as a framework that can revealingly synthesize a wide variety of representational functions of the brain. The framework is based on constructs from control theory (forward models) and signal processing (Kalman filters). The idea is that in addition to simply engaging with the body and environment, the brain constructs neural circuits that act as models of the body and environment. During overt sensorimotor engagement, these models are driven by efference copies in (...)

    Representational theories of mind cannot individuate the sense modalities in a principled manner. According to representationalism, the phenomenal character of experiences is determined by their contents. The usual objection is that inverted qualia are possible, so the phenomenal character of experiences may vary independently of their contents. But the objection is inconclusive. It raises difficult questions about the metaphysics of secondary qualities and it is difficult to see whether or not inverted qualia are possible. This paper proposes an alternative test (...)

There are two ways in which the location problem can be interpreted. First, it can be read as a why-question about the relation of visual experience to the environment represented: Why does visual experience represent a patch of color as located in this part of space rather than that? On this interpretation, the (...)

Some of these kinds, such as the sentential representations underlying language use and the pictorial representations of visual imagery, are thoroughly familiar to philosophers. Others have received almost no philosophical attention at all. Included in this latter category are analogue magnitude representations, which enable a wide range of organisms to primitively represent spatial, temporal, numerical, and related magnitudes.

    Attention Modulates Spatial Precision in Multiple‐Object Tracking.Nisheeth Srivastava & Ed Vul - 2016 - Topics in Cognitive Science 8 (1):335-348.
    We present a computational model of multiple-object tracking that makes trial-level predictions about the allocation of visual attention and the effect of this allocation on observers' ability to track multiple objects simultaneously. This model follows the intuition that increased attention to a location increases the spatial resolution of its internal representation. Using a combination of empirical and computational experiments, we demonstrate the existence of a tight coupling between cognitive and perceptual resources in this task: Low-level tracking of objects (...)

    Temporal Representation in the Control of Movement.Daniel M. Corcos - 1994 - Behavioral and Brain Sciences 17 (2):206-206.
    Theories of the representation of specific kinetic and spatiotem-poral features of movement range from the explicit assertion that temporal aspects of movement are not represented to the idea that they are represented and that they have neurophysiological correlates. Jeannerod's thesis is that mental and visual images have common mechanisms and that there is a link between the image to move and the mechanisms involved with movement. The target article takes the position that certain parameters are coded in motor (...) but that the duration of an action is not one of them. This position is based on the work of Gottlieb et al. and of Decety et al.. Both these studies are worth considering in detail. In Note 1, Jeannerod suggests that: “in time-constrained tasks subjects control the amplitude parameter of force impulses, whereas in spatially constrained tasks the duration of the force impulse is affected by accuracy demands.” This is not exactly correct. Excitation pulse intensity is modulated both in tasks that require spatial and those that require temporal accuracy. Excitation pulse duration is modulated for changes in movement distance and inertial load. If subjects are required to be very accurate spatially, they will move at less than maximum speed for a given distance and this is achieved by lower levels of excitation intensity. (shrink)

    In their study of reasoning with diagrammatic and non-diagrammatic representations, Larkin and Simon (1987) are concerned with _external_ representations and explicitly avoid drawing inferences about the bearing of their work on the issue of internal, mental representations. Nonetheless, we may infer the bearing of their work on internal representations from the theories of Kosslyn, Finke and other ‘pictorialists’ who take internal representations to be importantly like external ones regarding their ‘privileged’ spatial properties of depicting (...)

    Spatial Representation: Problems in Philosophy and Psychology.Naomi Eilan, Rosaleen A. McCarthy & Bill Brewer (eds.) - 1993 - Cambridge: Blackwell.
    Spatial Representation presents original, specially written essays by leading psychologists and philosophers on a fascinating set of topics at the intersection of these two disciplines. They address such questions as these: Do the extraordinary navigational abilities of birds mean that these birds have the same kind of grip on the idea of a spatial world as we do? Is there a difference between the way sighted and blind subjects represent the world 'out there'? Does the study of brain-injured (...)

  47. Binding Mechanisms in Visual Perception and Their Link With Neural Oscillations: A Review of Evidence From tACS. [REVIEW]Andrea Ghiani, Marcello Maniglia, Luca Battaglini, David Melcher & Luca Ronconi - 2021 - Frontiers in Psychology 12.
    Neurophysiological studies in humans employing magneto- and electro- encephalography increasingly suggest that oscillatory rhythmic activity of the brain may be a core mechanism for binding sensory information across space, time, and object features to generate a unified perceptual representation. To distinguish whether oscillatory activity is causally related to binding processes or whether, on the contrary, it is a mere epiphenomenon, one possibility is to employ neuromodulatory techniques such as transcranial alternating current stimulation. tACS has seen a rising interest due to (...)

    Phenomenal and Cognitive Factors in Spatial Perception.Gary Hatfield - 2012 - In Gary Hatfield & Sarah Allred (eds.), Visual Experience: Sensation, Cognition, and Constancy. Oxford University Press. pp. 35.
    This chapter provides an overview of the phenomenology of size perception and the use of instructions to tease apart phenomenal and cognitive aspects. It develops his own recent proposals concerning the geometry of visual space. The chapter proposes that visual space is contracted along the lines of sight. This contraction would explain the apparent convergence of railway tracks, but without invoking a “proximal mode” experience. Parallel railway tracks receding into the distance project converging lines onto the retinas. A (...)

    Predictable and Self-Initiated Visual Motion is Judged to Be Slower Than Computer Generated Motion.John A. Dewey & Thomas H. Carr - 2013 - Consciousness and Cognition 22 (3):987-995.
    Self-initiated action effects are often perceived as less intense than identical but externally generated stimuli. It is thought that forward models within the sensorimotor system pre-activate cortical representations of predicted action effects, reducing perceptual sensitivity and attenuating neural responses. As self-agency and predictability are seldom manipulated simultaneously in behavioral experiments, it is unclear if self-other differences depend on predictable action effect contingencies, or if both self- and externally generated stimuli are modulated similarly by predictability. We factorially combined variation in (...)
