In two experiments, we investigate to what extent various visual saliency cues in realistic visual scenes cause speakers to overspecify their definite object descriptions with a redundant color attribute. The results of the first experiment demonstrate that speakers are more likely to redundantly mention color when visual clutter is present in a scene as compared to when this is not the case. In the second experiment, we found that distractor type and distractor color affect redundant color (...) use: Speakers are most likely to overspecify if there is at least one distractor object present that has the same type, but a different color than the target referent. Reliable effects of distractor distance were not found. Taken together, our results suggest that certain visual saliency cues guide speakers in determining which objects in a visual scene are relevant distractors, and which not. We argue that this is problematic for algorithms that aim to generate human-like descriptions of objects, since these generally select properties that help to distinguish a target from all objects that are present in a scene.

This paper describes some components of a working system which drives a vehicle through cluttered real world environments under computer control, guided by images perceived through an onboard television camera. The emphasis is on reliable and fast low level visual techniques which determine the existence and location of objects in the world, but do not identify them. They include an interest operator for choosing distinctive regions in images, a correlator for finding matching regions in similar images, a geometric camera (...) solver which determines camera displacement and distance to objects from motion stereo information and an automatic distortion corrector which compensates for camera imperfections.

Background: Clinical research nurses experience unique challenges in the context of their role that can lead to conflict and moral distress. Although examined in many areas, moral distress has not been studied in clinical research nurses. Research aim: The aim of this study was to examine moral distress in clinical research nurses and the relationship between moral distress scores and demographic characteristics of clinical research nurses. Research design: This was a descriptive quantitative study to measure moral distress in clinical research (...) nurses using the Measure of Moral Distress – Healthcare Professionals (MMD-HP) administered electronically. Demographic data were also collected. Participants and research context: Registered nurses working in the clinical research nurse role ( N = 322) were recruited through use of social media, emails, digital flyers, and snowball recruitment. Data was analyzed using SPSS. Pearson’s correlation, independent t-test, and one-way ANOVA were performed to explore differences among the demographic variables. Ethical considerations: This study was approved by the Institutional Review Board at Texas Woman’s University. A consent statement was included, and completion of the questionnaire was construed as consent. Findings/results: Analysis revealed a mean overall moral distress score of 79.58 (SD = 64.27) and median of 67, with a range of 0–354. Moral distress scores were negatively correlated with clinical research nurse age ( r = 0-.156, p < 0.05). Reliability of the MMD-HP was demonstrated with a Cronbach’s alpha of 0.93. Conclusions: The findings demonstrate that clinical research nurses do experience moral distress and revealed a wide range of scores. Further research is necessary to determine potential patient impact due to moral distress and to develop processes to minimize moral distress in the clinical research setting. This study was conducted during the COVID-19 pandemic, and the digital recruitment methods proved effective in recruiting a wide range of clinical research nurses, both nationally and internationally.

In this paper, I take up the conciliatory-steadfast debate occurring within social epistemology in regards to the phenomenon of peer disagreement. I will argue, because the conciliatory perspective al-lows us to understand argumentation pragmatically—as a method of problem-solving within a community rather than as a method for obtaining the truth—that in most cases, we should not simply agree to disagree.

Focus+Context techniques are commonly used in visualization systems to simultaneously provide both the details and the context of a particular dataset. This paper proposes a new methodology to empirically investigate the effect of various Focus+Context transformations on human perception. This methodology is based on the shaker paradigm, which tests performance for a visual task on an image that is rapidly alternated with a transformed version of itself. An important aspect of this technique is that it can determine two different (...) kinds of perceptual cost: (i) the effect on the perception of a static transformed image, and (ii) the effect of the dynamics of the transformation itself. This technique has been successfully applied to determine the extent to which human perception is invariant to scaling and rotation [Rensink 2004]. In this paper, we extend this approach to examine nonlinear fisheye transformations of the type typically used in a Focus+Context system. We show that there exists a no-cost zone where performance is unaffected by an abrupt, noticeable fisheye transformation, and that its extent can be determined. The lack of perceptual cost in regards to these sudden changes contradicts the belief that they are necessarily detrimental to performance, and suggests that smoothly animated transformations between visual states are not always necessary. We show that this technique also can map out low-cost zones where transformations result in only a slight degradation of performance. Finally, we show that rectangular grids have no positive effect on performance, acting only as a form of visual clutter. These results therefore demonstrate that the perceptual costs of nonlinear transformations can be successfully quantified. Interestingly, they show that some kinds of sudden transformation can be experienced with minimal or no perceptual cost. This contradicts the belief that sudden changes are necessarily detrimental to performance, and suggests that smoothly animated transformations between visual states are not always necessary..

Indeterminate art invokes a perceptual dilemma in which apparently detailed and vivid images resist identification. We used event-related fMRI to study visual perception of representational, indeterminate and abstract paintings. We hypothesized increased activation along a gradient of posterior-to-anterior ventral visual areas with increased object resolution, and postulated that object resolution would be associated with visual imagery. Behaviorally, subjects were faster to recognize familiar objects in representational than in both indeterminate and abstract paintings. We found activation within a (...) distributed cortical network that includes visual, parietal, limbic and prefrontal regions. Representational paintings, which depict scenes cluttered with familiar objects, evoked stronger activation than indeterminate and abstract paintings in higher-tier visual areas. Perception of scrambled paintings was associated with imagery-related activation in the precuneus and prefrontal cortex. Finally, representational paintings evoked stronger activation than indeterminate paintings in the temporoparietal junction. Our results suggest that perception of familiar content in art works is mediated by object recognition, memory recall and mental imagery, cognitive processes that evoke activation within a distributed cortical network.

This paper presents GlamMap, a visualization tool for large, multi-variate georeferenced humanities data sets. Our approach visualizes the data as glyphs on a zoomable geographic map, and performs clustering and data aggregation at each zoom level to avoid clutter and to prevent overlap of symbols. GlamMap was developed for the Galleries, Libraries, Archives, and Museums (GLAM) domain in cooperation with researchers in philosophy. We demonstrate the usefulness of our approach by a case study on history of logic, which involves (...) navigation and exploration of 7100 bibliographic records, and scalability on a data set of sixty million book records.

continent. 1.3 (2011): 208-212. … intervals of destructuring paradoxically carry the momentum for the ongoing process by which thought and perception are brought into relation toward transformative action. —Brian Massumi, Parables for the Virtual: Movement, Affect, Sensation 1 Facing a blank canvas or blank page is a moment of pure potential, one that can be enervating or paralyzing. It causes a pause, a hesitation, in anticipation of the moment of inception—even of one that never comes. The implication is that the (...) blank is yours in that moment, and it calls on you to act on it, to think into it, to create on it. Each blank canvas gives you time, of an undefined length, to transform that canvas’ inherent potential into a work. This two-dimensional plane of potential can be projected into a space, which the body can then occupy. When you “destructure” a space in the same way, prepare it to be a blank, much as you build a canvas, you allow your entire body to enter the space of potential, and you rest in anticipation of work, like the hand poised above the page. Artists have found that the deliberate creation of that space of potential through sealing the space and painting it white, thereby erasing details and distractions, can be such a transformative experience as to help define their whole practice. The cessation of distraction, the absence of indicator that a “blanked” workspace provides allows for a new presence of mind, it gives them the room, literally, to move into their work, and from there to move their work into the world. The workspace for the artist, the studio, is often perceived as a lab-like condensation of the gallery or museum, the traditional and idealized white cube. Similarly, with the blank page, a concrete relation between space and time comes forward as the intentional simplification of the architecture changes behavior and perception within the space. The work of “blanking” the studio space is a meditative reduction, an erasure, and in a way, an attempt at drawing away from the world beyond the studio - the sealed space is meant to recede from reality, to become abstracted by its willed lack of details and distractions. Within that space the time for a new beginning is made more present, more attainable, and the focus it fosters becomes another tool to aid creation. At the formative moment of his artistic practice, Tom Friedman used the blank of his studio, saturated in white, sealed off from the world, to fight velocity. He describes how he projected his vision of the end goal, the museum - a place he believes to be defined by slow contemplation - onto his own studio experience. He then sat and reflected on common objects, one by one, framed by the blank box he had created. The domestic objects he brought into the space to study foreshadow his mature works, where often the quotidian object has a single additional element – his intense labor. Friedman makes discrete objects through absurdly intense and focused labor, epitomized, perhaps by his 1,000 hours of Staring , made from 1992-97: Tom Friedman. 1000 Hours of Staring (1992-1997) His labor, to use his own words, is his way to “bring all of who you are to the experience.” Friedman shares his labor, allows the slow, deliberate pace of his work born in the studio to penetrate the museum. Nothing seems effortless, or a gesture, the labor is apparent, displayed, and tangible. He gives us the labor, the personal investment in the physical that saved art for him, that divorced the work from the language he cites as a factor of alienation. When we see his work we do not see words, we see acts, we see objects. He has forced the studio as workspace into the exhibition space, as he stuffs hundreds of more hours of labor into his shows with each new piece, filling the space with material and labor, material and labor – his involvement, his investment, is his gift to us as the viewers, as he introduces the laborious and contemplative pace he feels belongs to the museum. He saves us also from the alienation of language, which first drove him into the sealed studio and away from the discourse of his school. He presents us with his real, the object which stands in stark contrast to the white slate of the studio, the sealed white box he started from, where his individual, self-contained objects begin and end, completed through the intensity of isolation, first of the individual artist, and then of the material he chooses to slowly, slowly, slowly work: Tom Friedman. Untitled (1992) In his in-depth analysis of galleries as a blank white cube, Brian O’Doherty emphasizes the religious connotations implied in the strict laws of the exhibition space and the valuation, aesthetics and elements of control he feels it imposes upon the work. Like Friedman, he recognizes the power of the restricted space – indicating the “perceptual fields of force” – that act on any object introduced into it. Going beyond Friedman’s assessment of the space as highly utilitarian for focusing his perception, O’Doherty emphasizes the rejection of the physical body of the artist or observer, saying that the cube allows for only observation - eyes and mind. He later parallels the picture frame as a psychological container for the artist with the room as the same for the observer. In both cases, this is an emphasis on the alienating nature of the relationship – just as the artist is kept out of the frame by the picture, in the gallery the art forces the body of the spectator out, calling for a self-referential purity. Patrick Ireland. White Cube (1998) O’Doherty makes a point of saying that the installation shot of the gallery without figures is “one of the icons of our visual culture.” In recent years, however, installation shots have begun to include figures, in some cases they are essential to understanding the scale and even the nature of the work, specifically with work that captures the experience of the space and the way that it varies from a white cube. The work of Olafur Eliasson is a case in point, as the Danish artist uses elements of scientific and natural phenomena to alter perception within the controlled gallery environment, tweaking and redirecting O’Doherty’s “perceptual fields of force” to make points about the act of seeing, or seeing yourself seeing, to quote the artist. This indicates a shift in the role of the artwork, not to exclude the body and stand discretely and self-sufficiently, but to include it, to manipulate it and to make the observer aware of the nature of that manipulation and the work’s ability to manipulate. Olafur Eliasson. 360º room for all colours (2002) So though in O’Doherty’s analysis, the intense blankness of the gallery pushed the observer out in favor of the artwork’s isolation, artists can replicate this inhumane sterility in their own workspace to focus their work on the influence of the gallery right from inception. This can be interpreted as an almost opposite understanding of the purpose of sealing and whitewashing the workspace as stated by Friedman. He sought a refuge from the critical language of the art school, and a space that, like the museum, gave him a protracted sense of time, and, he felt, welcomed him in, “to bring all of who you are,” as opposed to O’Doherty’s feeling that the museum was asking you, at least in body, to leave, and allow the work to take on its own life. Friedman does not seem to imply the tension with the cube and critical stance that O’Doherty prioritizes. Where Friedman finds a refuge, O’Doherty defines an opponent. In a third position, Robert Irwin describes his sealed studio space as “the world.” Though he made the same effort as Friedman to seal out all influences and distractions, he implies that he is in dialogue with the world through his own concentration and perception. This is reminiscent of the nature of the monad, as interpreted by Deleuze, a unity that envelops a multiplicity, a sealed container that contains the universe. He went through the same ritual described by Friedman, sealing up the space, painting it white, and then forcing himself to remain inside, staring at his own work, training his concentration relentlessly. But he found that the room became the distraction: …he became aware that a thin crack along the wall a few yards away from the canvas likewise exerted its presence; that when he plastered that crack over and repainted the wall, the canvas itself presented an entirely new aspect.2 The context was in a relentless dialogue with the work, and trying to neutralize that dialogue, to mute the conversation between space and object, became part of his ritual as he “fixed” his space each day in the hope of total concentration on the work. Ultimately, Irwin shaped the trajectory of his art by relinquishing the studio, establishing a post-studio practice, where the work is conceived and created out in the world, in dialogue with the world and reflective of the conditions it finds surrounding it. The white cube failed to ever achieve neutrality, his heightened concentration prevented him from ever neutralizing the space, so, instead of continuing to try to maintain the charade of a perfect blank, he acknowledged the unstoppable voice of place and turned all his efforts onto the object and the world, as a constant dialogue. Some artists push their studio space far from purity, domesticating it like a lair or a living room, and others destroy it, fill it with chaos or detritus, blacken or clutter it so as never to be starting from a blank, and thereby try to avoid the anxiety of facing that void. Similarly artists may never prepare a white canvas, a clean page, a marble block, or other form that is intentionally lacking, in order to try to escape the dialogue with emptiness. But Irwin, like O’Doherty, found an opponent in the white cube, and he learned not to fight it, rather he ended the conflict by making it an ally, an interlocutor, a collaborator. We can vainly strive to start from nothing, to find the lull, the clearing, and to always consider what we do in balance with the empty set. Somehow that intangible cloud of hazy nothingness, that softness of a lapse continually offers a place to bounce off of, to react to, to wrestle with, to rest with, in tension, or a place to begin.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Rhetoric 35.4 (2002) 267-296 [Access article in PDF] Allegory and Democratic Public Culture in the Postmodern Era Robert Hariman The man lies on the hotel bed, clad only in his underwear, as he watches the TV screen just beyond his feet. His right hand holds the remote control, which he uses to scan through the cable channels. To his left sits Abraham Lincoln, clothed in long-sleeved white (...) shirt and black pants and reading a book. Lincoln's long, angular frame is just a bit stooped, and his brow is slightly furrowed, as if long accustomed to thinking on the edge of melancholy. Lincoln is mulling over a statement by Walter Benjamin: "Allegories are, in the realm of thoughts, what ruins are in the realm of things" (Benjamin 1977, 178). 1Seated to the man's right is a woman wearing the terry cloth bathrobe provided by the hotel. She leans slightly forward, legs crossed, as she reads the New York Times Magazine cover story about President Clinton. "Listen to this," she says with a bemused smile. "In the clutter around his desk in the Oval Office stands not a single bust of a favorite predecessor, but five: Lincoln, Teddy Roosevelt, Truman and two of F.D.R., plus a statuette of Will Rogers for good measure. If governing is choosing, this collection is a metaphor for this President's trouble with choices, and he himself allows, 'That's the story of my Presidency, that desk'" (Purdum 1996, 36).The man says nothing as he continues to watch the succession of images on the screen: a lizard flicks its tongue in the desert heat; a child in a stroller laughs as she holds a strawberry ice cream cone; a congressman in blue suit, white shirt, and red tie jabs his finger into the air as he talks earnestly; cars plastered with automotive product logos curl around a race track; Fred and Ginger swirl around the dance floor; soldiers wade ashore at Omaha Beach; the Space Shuttle lifts off; Groucho lifts his eyebrows; Regis smiles; mushrooms and peppers simmer in a pan.The succession of images could go on indefinitely. The tableau remains static. The composition is an allegory: a figural presentation that organizes multiple interpretations regarding collective experience. It also contains and comments on other forms of itself: Clinton's desk is an example [End Page 267] of the figural anecdote that has been a staple of American public address. The manifold of televisual images exemplifies the allegorical encoding that operates within postmodern art forms, including fragmentary appropriation, paratactic association, encyclopedic range, and non-linear temporality. The statement by Benjamin illuminates the nature of allegory in a specific genre and historical period, and as it is a general mode of representation, and perhaps as it is a model for all textual interpretation.The composition also evokes a set of dialectical tensions that are characteristic of both allegory in general and fundamental anxieties in the contemporary period. Past and present sit side by side, but incongruously, as if by artifice alone. So it is also with the print and visual media, which are held together by mutual competencies but otherwise in figural isolation that perhaps represents different destinies. Likewise, one might wonder about the peculiar relationship between public affairs and private life: the succession of images on the screen adhere to no hierarchy of values, no principle of loyalty or sacrifice, no basis for discerning obligations or maintaining rights, yet they are replete with the paraphernalia of these concerns, and the arrangement of figures in the room likewise is at once suggestive yet inconclusive. If this tableau contains familiar features of the mass-mediated experience that now saturates American politics, one might wonder: Is the democratic tradition in ruins?Allegories give us dynamic juxtapositions in a static frame. This principle of composition seems particularly suited to periods of cultural change. To the extent that the genre of allegory has a history, it is one of eternal recurrence at periods of loss and fragmentation produced by the expansion of a new, somewhat... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Journal of Aesthetic Education 40.4 (2006) 65-76 MuseSearchJournalsThis JournalContents[Access article in PDF]Identity, Aesthetics, ObjectsGustavo GuerraIn September 1990 UCLA's Wright Art Gallery opened an exhibition entitled Chicano Art: Resistance and Affirmation 1965-1985 (now usually referred to as CARA). While CARA was one of several national events displaying nonmainstream art, it was also distinctive in its politics of self-representation. The artists participating in CARA insisted that they be described as (...) members of a Chicano art movement. With the term Chicano they hoped to step beyond labels preferred by the dominant culture—labels such as Mexican American, Latino, or Hispanic. For these artists, the word Chicano was appealing because it represented a complexity of meanings that they understood as being integral to both their identity and to the art they produced. The word Chicano, as Alicia Gaspar de Alba discusses in Chicano Art Inside/Outside the Master's House,1 embraces multiple meanings and axes of cultural identity; it derives from the Nahuatl pronunciation of Mexicano, often referring to a person of Aztec descent but including, as well, Native American heritage, Mexican roots, and Catholic faith. The CARA artists also embraced the label's association with a politics of liberation, popular protest, and working-class creativity. From the outset, then, the CARA exhibition was more than an art exhibition.By some lights, however, CARA was too much more than an art exhibition. When the organizers realized they needed funds, they applied for a National Endowment of the Humanities (NEH) grant and were initially turned down. While an NEH rejection might mean a number of things, the language of the rejection reports in this case narrows the possibilities down [End Page 65] to an issue that I mean to consider in this article. One rejection report states thatThe panelists understood that Chicano art arose from a variety of political movements and social causes, and therefore the political aspect of this proposal is appropriate to the subject matter.... Even so, the panelists worried that the project makes a political statement, that it is politics masquerading as culture, and that the proposal contains jargon and rhetoric and reads like a manifesto. 2Other reviewers objected to the general language of the report along similar lines. While Chicano artists made a point of representing themselves in complex, multidimensional terms, the NEH found such complexity and multidimensionality perplexing and thus their art not worthy of funding. One referee, for instance, claimed that the terminology used in the proposal was too narrow; he complained that defining Chicano in terms of struggle was too restrictive and excluded other Chicano artists for whom struggle was not a major concern. But later the same reporter objected that some of the concepts in the proposal were not inclusive enough, as they failed to include issues and topics that are central to the Chicano community. Thus the complexity and cluttered characterization that the artists felt was central to their sense of identity was dismissed as either too excessive or as too restrictive. According to the NEH, Chicano artists failed not because of their art (which the referees did describe as "visually compelling") but because of the way in which they chose to identify themselves—because, in other words, of their "rhetoric and jargon." Whatever it was that the NEH found compelling in the Chicano art they found uncompelling in the description of the Chicano artists' lives.After the organizers revised their proposal and reapplied for the grant, they were once again turned down. This second rejection highlights even more clearly the nature of the problem. This second report argues that "[T]here is a disjunction between the organizers' intentions and the exhibition. The proposal does not differentiate clearly between Chicano art and Hispanic art and, in its dependence on self-referential analysis rather than a comparative perspective, the exhibition does not place art in the bigger picture." 3I would like to consider what is at issue when descriptions of identity are said not to work, or when descriptions of art are likewise accused of failure and...

The squared paper or graphs are grid-based design representations used in engineering, industrial and craft design practices wherein designs are drawn over symmetrical grids. This paper reports grid-processing strategies undertaken by actors in a native craft practice, viz. Kashmiri carpet-weaving having three task contexts: (1) _design_, wherein designs are drawn on graph sheets and color scheme given by assigning practice-specific symbolic codes to the motifs by designers; (2) _coding_, wherein a cryptic script, called _talim_, is generated from these encoded graphs (...) by talim-writers; and (3) _weaving_, wherein this script is read, decoded and communicated in an equally cryptic trade-language by weavers among their teams. 32 video-recorded think-aloud sessions were conducted with talim-writers to understand their graph-processing and resultant coding strategies. The observations and qualitative analysis of transcripts revealed highly _situated_ strategies undertaken by experts keen on imbibing visuality of design embedded in the grids, in contrast to _embodied_ strategies undertaken by less-experienced coders keen on processing grids’ structural features and getting overwhelmed by grid-clutter in the process. In this landscape, the findings revealed a negotiated nature of errors instead of being deviations from the underlying grid and thereby objectively assessable. The paper makes recommendations for CAD systems to include more of those grid features exploited by experts during their graph processing to facilitate designers. (shrink)

First published in 1995, The Visual Brain in Action remains a seminal publication in the cognitive sciences. For this new edition, a very substantial and illustrated epilogue has been added to the book in which Milner and Goodale review the key developments that support or challenge the views that were put forward in the first edition.

This paper explores the philosophical aspects of a problem—clutter—that has gathered growing attention from social scientists, but not philosophers, in recent years. The central questions are: What role should things play as we go about the business of living? How can we modify our relationship to things to better reflect who we are—our values and the shape we want our lives to have? I offer an analysis of clutter in both objective and subjective terms, suggesting that the problem (...) of clutter lies on the subjective side. I then defend the claim that the problem stems from a mistaken sense of what kinds of action are appropriate with respect to things, given the attitudes called for by the recognition of value. My answer to the motivating questions, then, is that things can and should have personal value, and that once we recognize this, we are in a better position to see clearly the role they play in our identities and thus to respond appropriately to their value, thus preventing the experience of our stuff as clutter.

Gilbert Harman’s famous principle of Clutter Avoidance commands that “one should not clutter one’s mind with trivialities". Many epistemologists have been inclined to accept Harman’s principle, or something like it. This is significant because the principle appears to have robust implications for our overall picture of epistemic normativity. Jane Friedman (2018) has recently argued that one potential implication is that there are no genuine purely evidential norms on belief revision. In this paper, we present some new objections to (...) a suitably formulated version of the clutter principle qua norm on belief revision. Moreover, we argue that the clutter principle is best understood as a norm on non-doxastic stages of inquiry. In our view, it is a norm of asking and considering questions rather than a norm of settling on an answer to a question by forming a belief. (shrink)

The two contrasting theoretical approaches to visual perception, the constructivist and the ecological, are briefly presented and illustrated through their analyses of space and size perception. Earlier calls for their reconciliation and unification are reviewed. Neurophysiological, neuropsychological, and psychophysical evidence for the existence of two quite distinct visual systems, the ventral and the dorsal, is presented. These two perceptual systems differ in their functions; the ventral system's central function is that of identification, while the dorsal system is mainly (...) engaged in the visual control of motor behavior. The strong parallels between the ecological approach and the functioning of the dorsal system, and between the constructivist approach and the functioning of the ventral system are noted. It is also shown that the experimental paradigms used by the proponents of these two approaches match the functions of the respective visual systems. A dual-process approach to visual perception emerges from this analysis, with the ecological-dorsal process transpiring mainly without conscious awareness, while the constructivist-ventral process is normally conscious. Some implications of this dual-process approach to visual-perceptual phenomena are presented, with emphasis on space perception. Key Words: constructivist; dual-process approach; ecological; size perception; space perception; two visual systems; visual perception theories. (shrink)

Many of Margaret Cavendish’s criticisms of Thomas Hobbes in the Philosophical Letters (1664) relate to the disorder and damage that she holds would result if Hobbesian pressure were the cause of visual perception. In this paper, I argue that her “two men” thought experiment in Letter IV is aimed at a different goal: to show the explanatory potency of her account. First, I connect Cavendish’s view of visual perception as “patterning” to the “two men” thought experiment in Letter (...) IV. Second, I provide a potential reply on Hobbes’s behalf that appeals to physiological differences between perceivers’ sense organs, drawing upon Hobbes’s optics in De homine. Third, I argue that such a reply would misunderstand Cavendish’s objective of showing the limited explanatory resources available in understanding visual perception as pressing when compared to her view of visual perception as patterning.

Resumo: Nas últimas décadas, a pesquisa interdisciplinar tornou-se uma tendência. A linguagem visual e o pensamento cultural são dois diferentes conceitos, cada um com seus próprios métodos de pesquisa e seus referenciais teóricos. Entretanto, pesquisadores vêm percebendo que combinar a linguagem visual com o pensamento cultural pode oferecer compreensões e análises mais amplas e profundas. O propósito deste trabalho é ampliar o entendimento das pessoas sobre a linguagem visual e o pensamento cultural. Através da exploração interdisciplinar, as (...) conotações e os significados culturais, por trás das imagens, podem ser profundamente examinados, a fim de revelar as diferenças e semelhanças entre as diferentes culturas, o que ajuda a aumentar a conscientização da diversidade cultural e a promover a troca e o entendimento entre as diferentes culturas. Esta pesquisa pode ser usada como um recurso para o desenvolvimento social e ter um impacto significativo no desenvolvimento da economia, resultando em um novo pensamento cultural. Ao mesmo tempo, ela também é um fator central de poder tecnológico. Como um elemento e símbolo de soft culture, a linguagem pode desempenhar um papel na diplomacia pública e participar do pensamento cultural e da competição. À medida que a sociedade humana entra na era da mídia da internet, a vida e o equipamento linguístico das pessoas fazem um progresso significativo. (shrink)

Visual thinking -- visual imagination or perception of diagrams and symbol arrays, and mental operations on them -- is omnipresent in mathematics. Is this visual thinking merely a psychological aid, facilitating grasp of what is gathered by other means? Or does it also have epistemological functions, as a means of discovery, understanding, and even proof? By examining the many kinds of visual representation in mathematics and the diverse ways in which they are used, Marcus Giaquinto argues (...) that visual thinking in mathematics is rarely just a superfluous aid; it usually has epistemological value, often as a means of discovery. Drawing from philosophical work on the nature of concepts and from empirical studies of visual perception, mental imagery, and numerical cognition, Giaquinto explores a major source of our grasp of mathematics, using examples from basic geometry, arithmetic, algebra, and real analysis. He shows how we can discern abstract general truths by means of specific images, how synthetic a priori knowledge is possible, and how visual means can help us grasp abstract structures. Visual Thinking in Mathematics reopens the investigation of earlier thinkers from Plato to Kant into the nature and epistemology of an individual's basic mathematical beliefs and abilities, in the new light shed by the maturing cognitive sciences. Clear and concise throughout, it will appeal to scholars and students of philosophy, mathematics, and psychology, as well as anyone with an interest in mathematical thinking. (shrink)

Marcus Giaquinto presents an investigation into the different kinds of visual thinking involved in mathematical thought, drawing on work in cognitive psychology, philosophy, and mathematics. He argues that mental images and physical diagrams are rarely just superfluous aids: they are often a means of discovery, understanding, and even proof.

In this book, Michael Madary examines visual experience, drawing on both phenomenological and empirical methods of investigation. He finds that these two approaches—careful, philosophical description of experience and the science of vision—independently converge on the same result: Visual perception is an ongoing process of anticipation and fulfillment. Madary first makes the case for the descriptive premise, arguing that the phenomenology of vision is best described as on ongoing process of anticipation and fulfillment. He discusses visual experience as (...) being perspectival, temporal, and indeterminate; considers the possibility of surprise when appearances do not change as we expect; and considers the content of visual anticipation. Madary then makes the case for the empirical premise, showing that there are strong empirical reasons to model vision using the general form of anticipation and fulfillment. He presents a range of evidence from perceptual psychology and neuroscience, and reinterprets evidence for the two-visual-systems hypothesis. Finally, he considers the relationship between visual perception and social cognition. An appendix discusses Husserlian phenomenology as it relates to the argument of the book. Madary argues that the fact that there is a convergence of historically distinct methodologies itself is an argument that supports his findings. With Visual Phenomenology, he creates an exchange between the humanities and the sciences that takes both methods of investigation seriously. (shrink)

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

Visual Agnosia is a comprehensive and up-to-date review of disorders of higher vision that relates these disorders to current conceptions of higher vision from cognitive science, illuminating both the neuropsychological disorders and the nature of normal visual object recognition.Brain damage can lead to selective problems with visual perception, including visual agnosia the inability to recognize objects even though elementary visual functions remain unimpaired. Such disorders are relatively rare, yet they provide a window onto how the (...) normal brain might accomplish the complex task of vision. Visual Agnosia reviews a century of case studies of higher-level visual deficits following brain damage, places them in the general context of current neuroscience, and draws relevant conclusions about the organization of normal visual processing. It is unique in drawing on research in cognitive psychology, computational vision, visual neurophysiology, and neuropsychology to interpret the agnosias and draw inferences from them about visual object recognition.Following a historical account of agnosia research, Visual Agnosia offers a taxonomy of a wide range of agnosia syndromes, describing and interpreting the syndromes in terms of the latest theoretical models of visual processing and ultimately bringing them to bear as evidence on a variety of questions in the study of higher vision.Martha J. Farah is Associate Professor of Psychology at Carnegie Mellon University. Visual Agnosia is included in the Issues in Biology of Language and Cognition series, edited by John Marshall. (shrink)

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 brain imaging (...) and neuropsychology suggests that planning and control are subserved by separate visual centers in the posterior parietal lobes, each constituting part of a larger network for planning and control. Planning appears to rely on phylogenetically newer regions in the inferior parietal lobe, along with the frontal lobes and basal ganglia, whereas control appears to rely on older regions in the superior parietal lobe, along with the cerebellum.

According to so-called “thin” views about the content of experience, we can only visually experience low-level features such as colour, shape, texture or motion. According to so-called “rich” views, we can also visually experience some high-level properties, such as being a pine tree or being threatening. One of the standard objections against rich views is that high-level properties can only be represented at the level of judgment. In this paper, I first challenge this objection by relying on some recent studies (...) in social vision. Secondly, I tackle a different but related issue, namely, the idea that, if the content of experience is rich, then perception is cognitively penetrable. Against this thesis, I argue that the very same criteria that help us vindicate the truly sensory nature of our rich experiences speak against their being cognitively penetrable. (shrink)

With its own Netflix program, Marie Kondo's The Life-Changing Magic of Tidying Up has received a huge cult following. Considering that clutter sweeps 21st century daily living, what this paper aims to do, is to unravel the philosophical foundations of Kondo's work. Considering the trendiness of the KonMari method, one wonders why and how decluttering modern homes and one's day-to-day existence inspires certain profound reflections and raises social criticisms. Through a sweeping review of Kondo's tenets, this paper tackles common (...) philosophical themes such as joy, human existence, happiness, the environment and extension. (shrink)

A comment on Susan Wendell's paper "Oppression and Victimization; Choice and Responsibility" that appeared in Hypatia 5(3).

I develop a theory of what we mean by the 'look' sentences that we use to describe our visual experiences, and on that basis develop a new adverbial theory of what it is to have a visual experience with a certain character.

Argues for a category of “cognitive feelings”, which are representationally significant, but are not part of the content of the states they accompany. The feeling of pastness in episodic memory, of familiarity (missing in Capgras syndrome), and of motivation (that accompanies desire) are examples. The feeling of presence that accompanies normal visual states is due to such a cognitive feeling; the “two visual systems” are partially responsible for this feeling.

First published in 1995, The Visual Brain in Action remains a seminal publication in the cognitive sciences. It presents a model for understanding the visual processing underlying perception and action, proposing a broad distinction within the brain between two kinds of vision: conscious perception and unconscious 'online' vision. It argues that each kind of vision can occur quasi-independently of the other, and is separately handled by a quite different processing system. In the 11 years since publication, the book (...) has provoked considerable interest and debate - throughout both cognitive neuroscience and philosophy, while the field has continued to flourish and develop. -/- For this new edition, the text from the original edition has been left untouched, standing as a coherent statement of the authors' position. However, a very substantial epilogue has been added to the book in which Milner and Goodale review some of the key developments that support or challenge the views that were put forward in the first edition. The new chapter summarizes developments in various relevant areas of psychology, neuroscience and behaviour. It notably supplements the main text by updating the reader on the contributions that have emerged from the use of functional neuroimaging, which was in its infancy when the first edition was written. Neuroimaging, and functional MRI in particular, has revolutionized the field over the past 11 years by allowing investigators to plot in detail the patterns of activity within the visual brains of behaving and perceiving humans. The authors show how its use now allows scientists to test and confirm their proposals, based as they then were largely on evidence accrued from primate neuroscience in conjunction with studies of neurological patients.

Everyday visual experience constantly confronts us with things we can interact with in the real world. We literally feel the outside presence of physical objects in our environment via visual perceptual experience. The visual feeling of presence is a crucial feature of vision that is largely unexplored in the philosophy of perception, and poorly debated in vision neuroscience. The aim of this article is to investigate the feeling of presence. I suggest that visual feeling of presence (...) depends on the visual representation of a very particular spatial relation with the object we interact with: the visual representation of absolute egocentric depth, which is due to stereoscopic vision.

Our visual system can process information at both conscious and unconscious levels. Understanding the factors that control whether a stimulus reaches our awareness, and the fate of those stimuli that remain at an unconscious level, are the major challenges of brain science in the new millennium. Since its publication in 1984, Visual Masking has established itself as a classic text in the field of cognitive psychology. In the years since, there have been considerable advances in the cognitive neurosciences, (...) and a growth of interest in the topic of consciousness, and the time is ripe for a new edition of this text. Where most current approaches to the study of visual consciousness adopt a 'steady-state' view, the approach presented in this book explores its dynamic properties. This new edition uses the technique of visual masking to explore temporal aspects of conscious and unconscious processes down to a resolution in the millisecond range. The 'time slices' through conscious and unconscious vision revealed by the visual masking technique can shed light on both normal and abnormal operations in the brain. The main focus of this book is on the microgenesis of visual form and pattern perception - microgenesis referring to the processes occurring in the visual system from the time of stimulus presentation on the retinae to the time, a few hundred milliseconds later, of its registration at conscious or unconscious perceptual and behavioural levels. The book takes a highly integrative approach by presenting microgenesis within a broad context encompassing visuo-temporal phenomena, attention, and consciousness. (shrink)

I argue that we sometimes visually perceive the intentions of others. Just as we can see something as blue or as moving to the left, so too can we see someone as intending to evade detection or as aiming to traverse a physical obstacle. I consider the typical subject presented with the Heider and Simmel movie, a widely studied ‘animacy’ stimulus, and I argue that this subject mentally attributes proximal intentions to some of the objects in the movie. I further (...) argue that these attributions are unrevisable in a certain sense and that this result can be used to as part of an argument that these attributions are not post-perceptual thoughts. Finally, I suggest that if these attributions are visual experiences, and more particularly visual illusions, their unrevisability can be satisfyingly explained, by appealing to the mechanisms which underlie visual illusions more generally.

Visual number adaption is a widely accepted phenomenon. This paper advances an alternative explanation for putative cases of the phenomenon. We propose that such cases may simply reflect observers adapting to the items in perceived displays, rather than their numerical quantity. Three experiments motivate consideration of this novel proposal and call into question the evidential basis for received formulations of the number adaptation hypothesis.

Although the mechanics of how the eye works are well understood, debate still exists as to how the complex machinery of the brain interprets neural impulses...

Many who suffer from eating disorders claim that they see themselves as “fat”. Despite decades of research into the phenomenon, behavioural evidence has failed to confirm that eating disorders involve visual misperception of own-body size. I illustrate the importance of this phenomenon for our understanding of perceptual processing, outline the challenges involved in experimentally confirming it, and provide solutions to those challenges.

Visual representations (photographs, diagrams, etc.) play crucial roles in scientific processes. They help, for example, to communicate research results and hypotheses to scientific peers as well as to the lay audience. In genuine research activities they are used as evidence or as surrogates for research objects which are otherwise cognitively inaccessible. Despite their important functional roles in scientific practices, philosophers of science have more or less neglected visual representations in their analyses of epistemic methods and tools of reasoning (...) in science. This book is meant to fill this gap. It presents a detailed investigation into central conceptual issues and into the epistemology of visual representations in science. (shrink)

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

In this article we explore the relationship between semiotic analysis of images and quantitative analysis of vast image corpora, in particular the work produced by Lev Manovich and the Cultural Analytics Lab, called “Media Visualization.” Media Visualization has been chosen as corpus because of its metavisual operation (images are visualized and analyzed by images) and its innovating way of conceiving analysis: by visual instruments. In this paper semiotics is used as an approach to Media Visualization and taken as an (...) object of study as well, especially visual semiotics. In this sense, a comparison between visual semiotics (close reading of small corpora) and quantitative analyses of images (distant reading of vast collections) are conducted from a semiotic point of view. Post-Greimassian semiotics guides this study with respect to the issue of the image-within-an-image and metavisual visualization; Peircean semiotics is employed to explain and develop the notion of diagram.
