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, when looking at a picture aesthetically, one both consciously represents and visually attends to both the depicted object and the picture’s surface simultaneously. Thus, contra the empirical research on attention, only conscious visual representations are coupled, by such current view, with attention. And this clearly poses a second problem, as this philosophical account is not in tune with what vision science tells us about the functioning of our visual system. Furthermore, this raises another crucial problem, namely, that of explaining why aesthetic experience of pictures does not feel odd or conflicting, since, as previously noted in the philosophical literature, and contra the received view, if we are simultaneously consciously perceiving both the picture’s surface and the depicted object, there seems to be two things, at the same time, in the foreground of one’s visual consciousness. But, if so, as suggested, this would lead to a conflicting spatial visual experience. This paper offers a new description of the role of visual attention in picture perception, which explains the difference between the usual and the aesthetic way of perceiving a depicted object, without facing the problems reported above. A crucial role in our new account is played by the notion of unconscious attention, the distinction between focal and distributed, as well as top-down and bottom-up visual attention and the relationship between visual attention and visual consciousness. The paper, thus, offers the first theory concerning the exercise of visual attention in pictorial perception that is both philosophically rigorous and empirically reliable. (shrink)

Richly illustrated study drawing on art, literature and science to explore Victorian attitudes towards sight.

Schizophrenia is associated with a series of visual perception impairments, which might impact on the patients’ every day life and be related to clinical symptoms. However, the heterogeneity of the visual disorders make it a challenge to understand both the mechanisms and the consequences of these impairments, i.e., the way patients experience the outer world. Based on earlier psychiatry literature, we argue that issues regarding time might shed a new light on the disorders observed in patients (...) with schizophrenia.We will briefly review the mechanisms involved in the sense of time continuity and clinical evidence that they are impaired in patients with schizophrenia.We will then summarize a recent experimental approach regarding the coding of time-event structure in time, namely the ability to discriminate between simultaneous and asynchronous events. The use of an original method of analysis allowed us to distinguish between explicit and implicit judgments of synchrony.We showed that for SOAs below 20ms neither patients nor controls fuse events in time. On the contrary subjects distinguish events at an implicit level even when judging them as synchronous. In addition, the implicit responses of patients and controls differ qualitatively. It is as if controls always put more weight on the last occurred event, whereas patients have a difficulty to follow events in time at an implicit level. In patients, there is a clear dissociation between results at short and large asynchronies, that suggest selective mechanisms for the implicit coding of time-event structure. These results might explain the disruption of the sense of time continuity in patients.We argue that this line of research might also help us to better understand the mechanisms of the visual impairments in patients and how they see their environment.

This volume contains new papers addressing a number of new and traditional issues pertaining to the roles of representations in visual perception. Among these issues is the one concerning the nature of the perceptual state itself – e. g. on the issue of whether the perceptual state, like its distal objects, is structured, for instance by possessing a spatial character. Other issues include those of whether at least aspects of the distal object are presented immediately to us visually, (...) whether representation plays any (interesting) role in disjunctivist and naïve realist accounts of visual experience and the relationship among visual perception, attention and representation. The anthology includes a wide variety of positions on the subject of the roles of representations in visual perception, which would help to close the literature gap and will be of interest to scholars from all schools and trends of philosophy of mind.

Emotionally arousing events reach awareness more easily and evoke greater visual cortex activation than more mundane events. Recent studies have shown that they are also perceived more vividly and that emotionally enhanced perceptual vividness predicts memory vividness. We propose that affect-biased attention (ABA) – selective attention to emotionally salient events – is an endogenous attentional system tuned by an individual's history of reward and punishment. We present the Biased Attention via Norepinephrine (BANE) model, which unifies genetic, neuromodulatory, neural and (...) behavioural evidence to account for ABA. We review evidence supporting BANE's proposal that a key mechanism of ABA is locus coeruleus–norepinephrine (LC–NE) activity, which interacts with activity in hubs of affective salience networks to modulate visual cortex activation and heighten the subjective vividness of emotionally salient stimuli. We further review literature on biased competition and look at initial evidence for its potential as a neural mechanism behind ABA. We also review evidence supporting the role of the LC–NE system as a driving force of ABA. Finally, we review individual differences in ABA and memory including differences in sensitivity to stimulus category and valence. We focus on differences arising from a variant of the ADRA2b gene, which codes for the alpha2b adrenoreceptor as a way of investigating influences of NE availability on ABA in humans. (shrink)

BackgroundIn Sweden, individuals with visual field loss have their driving license withdrawn. The literature clearly indicates that individuals with VFL are unsafe drivers on a group level. However, many drivers with VFL can be safe on an individual level. The literature also suggests that self-perception, beliefs, and insights of one’s own capabilities are related to driving performance. This study had three aims: To investigate self-perceived driving capability ratings for individuals with VFL; to compare these ratings between (...) groups with different medical conditions associated with VFL ; and to relate the self-perception ratings to actual driving performance in an advanced driving simulator.MethodsParticipants comprised 723 individuals whose driver’s license had been withdrawn because of VFL and 92 normally sighted elderly individuals. All participants completed a background survey, rated difficulties with different traffic situations, rated their strengths and weaknesses as drivers, and rated aspects that were important for causing traffic accidents. Of the VFL group participants, 264 also completed a simulator-based driving test that they knew could lead to renewal of their driving license. VFL participants and normally sighted was at the same age when they completed the simulator driving test.ResultsOverall, individuals with VFL rated their capabilities as high on all instruments and scales used, even higher than the elderly normally sighted control group. The only VFL etiology group that rated lower than other groups was the diabetes group. Safety orientation and internal control orientation values were best at discriminating between VFL participants in terms of self-perception of driving performance. Participants categorized as “high” in terms of safety skills and internal control were more modest in their ratings. Finally, participants who passed the simulated driving test did not differ from those who failed, in any of the self-perception measures.ConclusionSelf-perception ratings among individuals with VFL were higher than those of normally sighted elderly individuals. Self-assessed skills did not predict driving performance. Groups with different VFL etiologies rated similarly. Self-ratings of driving abilities cannot be used to assess actual driving performance. Actual driving tests are necessary to discriminate between safe and unsafe drivers with VFL. (shrink)

In the beginning was the night. All light, shapes, language, and subjective consciousness, as well as the world and art depicting them, emerged from this formless chaos. In fantasy, we seek to return to this original darkness. Particularly in literature, visual representations, and film, the night resiliently resurfaces from the margins of the knowable, acting as a stage and state of mind in which exceptional perceptions, discoveries, and decisions play out. Elisabeth Bronfen investigates the nocturnal spaces in which (...) extraordinary events unfold, and casts a critical eye into the darkness that enables the irrational exploration of desire, transformation, ecstasy, transgression, spiritual illumination, and moral choice. She begins with an analysis of classical myths depicting the creation of the world and then moves through night scenes in Shakespeare and Milton, Gothic novels and novellas, Hegel's romantic philosophy, and Freud's psychoanalysis. Bronfen also demonstrates how modern works of literature and film, particularly film noir, can convey that piece of night the modern subject carries within. From Mozart's "Queen of the Night" to Virginia Woolf 's oscillation between day and night, life and death, and chaos and aesthetic form, Bronfen renders something visible, conceivable, and comprehensible from the dark realms of the unknown.

We study the claim that multisensory environments are useful for visual learning because nonvisual percepts can be processed to produce error signals that people can use to adapt their visual systems. This hypothesis is motivated by a Bayesian network framework. The framework is useful because it ties together three observations that have appeared in the literature: (a) signals from nonvisual modalities can “teach” the visual system; (b) signals from nonvisual modalities can facilitate learning in the (...) class='Hi'>visual system; and (c) visual signals can become associated with (or be predicted by) signals from nonvisual modalities. Experimental data consistent with each of these observations are reviewed. (shrink)

The following dissertation shows how German Literature negotiates the relationship between language and the visual arts, particularly in Romantic narratives. In contrast with authors of the Enlightenment, the Romantics tend to deny specificity to visual experience and in so doing dedifferentiate visual experience from the textual. ;The initial, methodological, chapter explicates perceptual models informed by the interplay of the philosophical approaches of Kant and Wittgenstein with the psychoanalytic discourse of Freud. In Chapter Two, I turn to (...) Lessing's Laokoon Uder uber die Grenzen der Malerei und Poesie , in which he divides the arts into pictoral and linguistic signs. While the boundary between the two appears quite clear in Laokoon, his play Emilia Galotti reveals Lessing's anxiety that the difference cannot be so easily maintained. ;The subsequent chapter explores the representation of the visual arts in Tieck's Franz Sternbalds Wanderungen . After a discussion of Wackenroder's Herzensergiessungen eines kunstliebenden Klosterbruders , 1 turn to Tieck's novel about a young student of Albrecht Durer. The novel responds to the ostensible binary between language and the visual arts by transmuting the distinction into one between readable landscape paintings and phantasmatic images that guide the protagonist. ;As another example of this Romantic viewpoint, I analyze Brentano's Godwi oder das steinerne Bild der Mutter . Here I use the distinction between symbol and allegory to point out the ways in which the text turns the difference between the arts into one between rhetorical figures. A similar manifestation of the problem occurs in Eichendorff's Das Marmorbild , discussed in Chapter Five. The novella follows the same lines as Lessing's Laokoon, thematizing the materiality of its eponymous marble statue. My final chapter concerns Kleist's model of visual perception, which is closely bound to his theology in his tales "Die heilige Cacilie" and "Der Findling" . ;Writing Images interprets the role of visuality in German Romantic literature in order to understand an unresolved problematic of late eighteenth and early nineteenth-century thought for those who would too quickly either differentiate between or conflate the visual and the written.

In lieu of an abstract, here is a brief excerpt of the content:The Journal of Aesthetic Education 40.3 (2006) 92-114 [Access article in PDF] A Global Art System: An Exploration of Current Literature on Visual Culture, and a Glimpse at the Universal Promethean Principle—with Unintended Oedipal Consequences Art Education 11-18: Meaning, Purpose And Direction, edited by Richard Hickman; New York, Continuum; 2nd edition, 2004; 176 pp. Global Visual Culture within a Global Art System I have harbored misgivings (...) about the term "visual culture" for several years. Having read Hickman's book with its collection of notable scholars in art and design education, those misgivings turned into qualified acceptance of "visual culture"—so long as it is understood as a global visual culture within a global art system. The ten chapters presented in Hickman's book clearly explore the notion of visual culture in the context of generating an expansive and appropriate canon of art distinctly relevant to our postmodern, multicultural, multidimensional classroom of multiple intelligences.1 And so, art and design education for the twenty-first century must perform three essential functions: one, it must color the classroom with signs of global human pictorial and textual expressions; two, it must attempt to comprehend an immeasurable universe through creative, scaled-down explorations of the phenomenal world all of humanity is subject to; and three, it must open up the Blakeian doors of perception,2 while remaining free of emotional, educational, social, political, or religious ideological bonds. In this light, Hickman's Art Education 11-18 (2004), is a must read for art and design educators currently bogged down in old curriculum, and a must read for educators who incorporate new pedagogical literature easily into their new curriculum. And I say must read because we are on the verge of a revolution in visual art history and education—immersed in it, struggling to make sense of our beloved classical canon of art, and struggling to come to grips with a strangely foreign, beautifully alien, semeiotic reality we call (vaguely) "visual culture." It is a visual culture and history from the north, east, and south. Not just from the west.Key innovative educational issues addressed in these chapters are (respectively) using the dynamic nature of art to expand the curricula (Richard Hickman); the collapse of cultural borders (Lesley Burgess and Nicholas [End Page 92] Addison); a balanced cultural history of the world (Colin Grigg); recognizing art and recognizing visual culture (Howard Hollands); a range of visual cultures and literacy (Darren Newbury); using computer technology as a pathway to a new art and visual culture (Andy Ash); critical study and analysis (Michele Tallack); hand-making as a universal link to nature and art (Rachel Mason); spirituality in the process of art creation (James Hall); and cross-cultural heritage toward a new canon of art (Hickman).I will review each chapter as it pertains to current literature exploring popular pedagogical terms like "visual culture," "postmodernism," "pluralism," and "radicalism" and (more importantly) as it fits into a global system of art and culture. In addition, I suggest another term ("cosmopolitanism"—to identify the viable gay and lesbian aesthetic and culture) not that they are necessarily different, but they are indeed relevant and operate from a fresh literary and historical perspective. Then, I will illustrate how a new, postmodern canon of art must be linked to global visual culture and art in order to expand the concept of visual culture. Thus, I see two tasks before me: the first task is to inventory the philosophy, pedagogy, and meanings within each of the ten chapters in Hickman's Art Education 11-18; and the second task is to integrate key pedagogical ideas highlighted in each chapter as a method of generating a meaningful, holistic, integrated direction for art and design education in the twenty-first century. Integrating Art and Design Education Art is a design process. All subject regimes, D. N. Perkins suggests, are a design process.3 This may seem too obvious now after all these years since the publication of Knowledge... (shrink)

Kant, Wittgenstein, and Husserl all held that visual awareness of objects requires visual awareness of the space in which the objects are located. There is a lively debate in the literature on spatial perception whether this view is undermined by the results of experiments on a Balint’s syndrome patient, known as RM. I argue that neither of two recent interpretations of these results is able to explain RM’s apparent ability to experience motion. I outline some ways (...) in which each interpretation may respond to this challenge, and suggest which way of meeting the challenge is preferable. I conclude that RM retains some awareness of the larger space surrounding the objects he sees. (shrink)

This book combines approaches from philosophy, psychology, and neuroscience in the study of perception. In addition to appealing to readers from all three of these disciplines, Perception: The Basics is a perfect introduction for students and general readers. Its interdisciplinary coverage of all aspects of perception does not require familiarity with either abstract philosophical concepts or neuroscientific knowledge. -/- Besides addressing the classic questions of how perception works, the book highlights the intricate connections between perception (...) and action as well as perception that is not triggered by sensory input, like mental imagery, dreaming, and hallucination. Further, the book balances out an overemphasis on vision in the literature by giving almost equal coverage to all the sense modalities (although some examples are easier to present in visual form).

Recent discussions in the philosophy of psychology have examined the use and legitimacy of such notions as “representation”, “content”, “computation”, and “inference” within a scientific psychology. While the resulting assessments have varied widely, ranging from outright rejection of some or all of these notions to full vindication of their use, there has been notable agreement on the considerations deemed relevant for making an assessment. The answer to the question of whether the notion of, say, representational content may be admitted into (...) a scientific psychology has often been made to hinge upon whether the notion can be squared with our “ordinary” or “folk” style of psychological explanation, with its alleged commitment to the idiom of beliefs and desires. In this article, I proceed the other way around, starting with experimental psychology itself and asking whether such notions as the above play a legitimate role within a particular area of contemporary theory, the psychology of perception. My conclusion will be that especially the first three have a legitimate place in theories of perception, albeit one that differs from that ascribed to them in a significant portion of the philosophical literature. Along the way I develop a notion of noncognitive functional analysis, which separates the notion of contentful perceptual processing and perceptual representation from cognitive or conceptual content.

We present an investigation into the relation between design princi- ples in Japanese gardens, and their associated perceptual effects. This leads to the realization that a set of design principles described in a Japanese gardening text by Shingen (1466), shows many parallels to the visual effects of perceptual grouping, studied by the Gestalt school of psychology. Guidelines for composition of rock clusters closely relate to perception of visual figure. Garden design elements are arranged into patterns that simplify (...) figure-ground segmentation, while seemingly balancing the visual salience of subparts and the global arrangement. Visual ‘ground’ is analyzed via medial axis transformation (MAT), often associated with shape perception in humans. MAT analysis reveals implicit structure in the visual ground of a quintessential rock garden design. The MAT structure enables formal com- parison of structure of figure and ground. They share some aesthetic qualities, with interesting differences. Both contain naturalistic asymmetric, self-similar, branching structures. While the branching pattern of the ground converges towards the viewer, that of the figure converges in the opposite direction. (shrink)

Any even cursory examination of what it is to exchange words about X or to exchange views about Y requires hard thought about what it is to exchange, period. How do we invest in what we give out, and how do we get it back? In kind, or differently moneyed? And, more crucial to the topic into which I am about to make a foolhardy plunge, is there such a thing as free exchange? And if so, what is it worth?How (...) do we perceive worth anyway? What relation does such perception of the invisible system of the initially visible coinage of exchange bear to present visual perception, and then to seeing? And what does perception matter anyway, in relation to writing, reading, and exchanging words? Which is primary?All these questions—in their institutional setting, or then in their freedom from context—can themselves be related to and gathered up into the notion of translation, or the carrying over from one side to, and into, another. All we can learn about speaking and the ways it is taught, reading and the ways we learn it, seeing and the ways it teaches us is translated and transported from sight and its constraints and choices to language and its own. How we read both is itself a subject of choice and constraint, of freedom and explicit value-placing, of variety and fidelity to certain ends.

Measures of visual cortical development in children demonstrate high variability and inconsistency throughout the literature. This is partly due to the specificity of the visual system in processing certain features. It may then be advantageous to activate multiple cortical pathways in order to observe maturation of coinciding networks. Visual stimuli eliciting the percept of apparent motion and shape change is designed to simultaneously activate both dorsal and ventral visual streams. However, research has shown that such (...) stimuli also elicit variable visual evoked potential (VEP) morphology in children. The aim of this study was to describe developmental changes in VEPs, including morphological patterns, and underlying visual cortical generators, elicited by apparent motion and shape change in school-aged children. Forty-one typically developing children underwent high-density EEG recordings in response to a continuously morphing, radially modulated, circle-star grating. VEPs were then compared across the age groups of 5-7, 8-10, and 11-15 years according to latency and amplitude. Current density reconstructions were performed on VEP data in order to observe activated cortical regions. It was found that two distinct VEP morphological patterns occurred in each age group. However, there were no major developmental differences between the age groups according to each pattern. Current density reconstructions further demonstrated consistent visual generators across age and pattern. These results describe two novel VEP morphological patterns in typically developing children, but with similar underlying cortical sources. The importance of these morphological patterns is discussed in terms of future studies and the investigation of a relationship to visual cognitive performance. (shrink)

In recent decades, and with the rise of the biological sciences, the color literature especially has taken seriously evidence from ethology and comparative psychology. However, there has been significantly less discussion of comparative cases in other areas of philosophy of perception. This essay aims to bring insights from animal studies into dialogue with more traditional ways of thinking about the perception of size. It argues that an indexing approach to perceptual representation, pioneered by Prettyman (Perceptual content is (...) indexed to attention. Synthese, 194(10), 4039–4054, 2017) in response to evidence of attentional effects in perception, cannot fully address the challenge. (shrink)

An active engagement with arts in general and visual arts in particular has been hypothesized to yield beneficial effects beyond arts itself. So-called cognitive and socio-emotional “transfer” effects into other domains have been claimed. However, the empirical basis of these hopes is limited. This is partly due to a lack of experimental comparisons, theory-based designs, and objective measurements in the literature on transfer effects of arts education. Therefore, the aim of the present study was to design and experimentally (...) investigate a theory-based visual-arts education program for adolescents aged between 12 and 19 years. The program was delivered in a museum context in three sessions and was expected to yield specific and objectively measurable transfer effects. To conduct a randomized field trial, three strictly parallelized and standardized art courses were developed, all of which addressed the topic of portrait drawing. The courses mainly differed regarding their instructional focus, which was either on periods of art history, on the facial expression of emotions, or on the self-perception of a person in the context of different social roles. In the first and more “traditional” course portrait drawing was used to better understand how portraits looked like in former centuries. The two other courses were designed in a way that the artistic engagement in portrait drawing was interwoven with practicing socio-emotional skills, namely empathy and emotion recognition in one course and understanding complex self-concept structures in the other. We expected positive socio-emotional transfer effects in the two “psychological” courses. We used an animated morph task to measure emotion recognition performance and a self-concept task to measure the self-complexity of participants before and after all three courses. Results indicate that an instructional focus on drawing the facial expressions of emotions yields specific improvements in emotion recognition, whereas drawing persons in different social roles yields a higher level of self-complexity in the self-concept task. In contrast, no significant effects on socio-emotional skills were found in the course focussing on art history. Therefore, our study provides causal evidence that visual-arts programs situated in an art-museum context can advance socio-emotional skills, when designed properly. (shrink)

In adult humans, conscious visual experience is shaped by particular cultural practices, as evidenced in the cross-cultural literature. In addition, the practices of our own culture already inform attempts to assess the experience of newborns or other animals.

In a recent paper, ‘Peripersonal perception in action’ (Synthese, 2018), Frédérique de Vignemont tackles the problem of defining what is peculiar to the visual perception of objects falling within the peripersonal space of the observer, i.e. the space immediately surrounding the body, and which is commonly described as the space in which action takes place. In this paper, I first discuss the proposal offered by de Vignemont about what characterizes peripersonal perception. Then, I suggest an extension (...) of this account that offers a meticulous description of the nature of the Content of Peripersonal Visual Experience - a topic never explicitly considered in the philosophical literature on vision - by discussing some peculiar features of it that, as recognized also by de Vignemont’s account, still need to be explained. In particular, I offer a philosophical examination of the specificity of peripersonal visual experience, in relation to its phenomenological dimension, its optical mechanisms and its neurophysiological underpinnings, in the light of our best theories from vision science, and in comparison to the visual experience of other visual spaces.

Acoustic experiences of nature represent a growing area in restorative environments research and are explored in this narrative literature review. First, the work surveyed indicates that nature is broadly characterized by the sounds of birdsong, wind, and water, and these sounds can enhance positive perceptions of natural environments presented through visual means. Second, isolated from other sensory modalities these sounds are often, although not always, positively affectively appraised and perceived as restorative. Third, after stress and/or fatigue nature sounds (...) and soundscapes can lead to subjectively and objectively improved mood and cognitive performance, as well as reductions in arousal, although some inconsistencies in findings are observed. Fourth, theoretical frameworks of restorative environments would benefit from inclusion of acoustic environmental properties such as sound intensity or frequency. Fifth, findings regarding positive, learned semantic associations with nature have arisen as a result of recent work on sounds and restoration. This represents another important area of potential theoretical development for broader restorative environments research. (shrink)

Following on from ecological theories of perception, such as the one proposed by [Gibson, J. J. . The senses considered as perceptual systems. Boston: Houghton Mifflin] this paper reviews the literature on the multisensory interactions underlying the perception of flavor in order to determine the extent to which it is really appropriate to consider flavor perception as a distinct perceptual system. We propose that the multisensory perception of flavor may be indicative of the fact that (...) the taxonomy currently used to define our senses is simply not appropriate. According to the view outlined here, the act of eating allows the different qualities of foodstuffs to be combined into unified percepts; and flavor can be used as a term to describe the combination of tastes, smells, trigeminal, and tactile sensations as well as the visual and auditory cues, that we perceive when tasting food.

Jerry Fodor wrote the following assessment of Danto’s importance in 1993: “Danto has done something I’ve been very much wanting to do: namely, reconsider some hard problems in aesthetics in the light of the past 20 years or so of philosophical work on intentionality and representation” (Fodor 1993, p. 41). Fodor is absolutely right: some of Danto’s work could be thought of as the application of some influential ideas about perception that Fodor also shared. The problem is that these (...) ideas have turned out to be false. Both Danto and Fodor are modularist: they both think that perception is an encapsulated process that is in no way influenced by any kind of non-perceptual processing (see, e.g., Fodor 1983, Pylyshyn 1984). Many of Danto’s famous and influential arguments rely very directly on this modularist assumption. There is now, however, a wealth of evidence against modularism of the strong kind held to by Danto and Fodor. We now know that perceptual experience is not determined entirely by the retinal input: our visual processing is influenced at various point in a top-down manner. What we know and what kinds of visual stimuli we have encountered previously deeply influence how the retinal input is processed. The empirical literature on this is vast and conclusive (for an overview, see Teufel and Nanay 2017 but see also the references in the last section of this paper). What does this mean for Danto’s views on art and perception? While one of Danto’s premises may turn out to be false, the history and examples he gave are valuable and bear repeating. Even more importantly, Danto’s aesthetics can in part be separated out from his modularism, leading us to draw slightly different but arguably even more interesting conclusions from famous thought experiments such as the Gallery of Indiscernibles.

Understanding how activity in the brain leads to a subjective percept is of great interest to philosophers and neuroscientists alike. In the last years, neurophysiological experiments have approached this problem directly by measuring neural signals in animals as they experience well-defined visual percepts. Stimuli in these studies are often inherently ambiguous, and thus rely upon the subjective report, generally from trained monkeys, to provide a measure of perception. By correlating activity levels in the brain to this report, one (...) can speculate on the role of individual neurons and groups of neurons in the formation and maintenance of a particular percept. However, in order to draw valid conclusions from such experiments, it is critical that the responses accurately and reliably reflect what is perceived. For this reason, a number of behavioural paradigms have been developed to control and evaluate the truthfulness of responses from behaving animals. Here we describe several approaches to optimizing the reliability of a monkey's perceptual report, and argue that their combination provides an invaluable approach in the study of subjective visual perception.

Covert spatial attention alters the way things look. There is strong empirical evidence showing that objects situated at attended locations are described as appearing bigger, closer, if striped, stripier than qualitatively indiscernible counterparts whose locations are unattended. These results cannot be easily explained in terms of which properties of objects are perceived. Nor do they appear to be cases of visual illusions. Ned Block has argued that these results are best accounted for by invoking what he calls ‘mental paint’. (...) In this paper I argue, instead, in favour of an account of these phenomena in terms of the perceptual experience of affordances concerning saccadic eye movement. As part of the argument I draw connections with the empirical literature on the way in which performance efficiency also alters visual appearance. (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.

The behavioral immune system (BIS) includes perceptual mechanisms for detecting cues of contamination. Former studies have indicated that moisture has a disgusting property. Therefore, moisture could be a target for detecting contamination cues by the BIS. We conducted two experiments to examine the psychophysical basis of moisture perception and clarify the relationship between the perception of moisture and the BIS. We assumed that the number of high luminance areas in a visual image provided optical information that would (...) enable the visual perception of moisture. In two experiments, we presented eight images of dough that contained different amounts of moisture as experimental stimuli. The amount of moisture shown in the images was increased in eight steps, from 28.6% to 42.9% of the total weight of the dough. In Experiment 1, the images were randomly presented on a computer display, and the participants (n = 22) were asked to rank the images in the order of the visually perceived moisture content. In Experiment 2, the participants (n = 15) completed pairwise comparisons based on the perceived moistness of the images. Furthermore, to examine the BIS responses, the participants rated the strength of disgust evoked by the stimuli, their motivation to avoid touching the stimuli, and the estimated magnitude of the risk of contamination by physical contact with the stimuli. The results indicated that the moisture content and the numbers of high luminance areas in the images accurately predicted the perception of moisture, suggesting that the detection of visual moisture was highly accurate, and the optical information served as an essential perceptual cue for detecting moisture. On the other hand, the BIS responses peaked in response to stimuli having approximately 33% to 39% moisture content. These results show that objects containing a moderate amount of moisture could be the target of visually detecting pathogens by the BIS. (shrink)

Does perceptual experience consist of a single, well-ordered timeline? Many seem to assume that it does, so that for each event, we can report whether it was before, after, or simultaneous with any other event. Few have addressed the issue head on. In addition to reviewing the little available literature on this foundational topic, this chapter goes on to discuss various findings in temporal order judgments and related tasks. From these findings, some have concluded that the brain actively reconstructs (...) the exact timing of visual, auditory, and tactile events based on factors such as perceived distance and the longer travel time of sound compared to light. But this literature is not conclusive. Results reported in older, rather neglected literature suggest that rather than perceived timing being the result of sophisticated temporal reconstruction, perceived timing is often a byproduct of Gestalt-like grouping principles.

How much is given in perceptual experience, and how much must be constructed? John Locke's answer to this question contains two prima facie incompatible strands. On the one hand, he claims that ideas of primary qualities come to us passively, through multiple senses: the idea of a sphere can be received either by sight or touch. On the other hand, Locke seemingly thinks that a faculty he calls “judgment” is needed to create visual ideas of three‐dimensional shapes. How can (...) these accounts be made consistent? The problem comes to a head in the discussion of Molyneux's problem: can a person born blind and then made to see identify a sphere and a cube, when he had only touched them in the past? Locke's answer is no, but, as George Berkeley points out, it is hard to see why: if the ideas of shapes come to us through sight as well as touch, nothing should stop Molyneux man from instantly recognizing sphere and cube. Pace much of the existing literature, I argue that although Locke does think we receive visual ideas of primary qualities, the faculty of judgment is required to “inflate” those ideas into three dimensions and to correct for other perspectival distortions. I then show how this answer is consistent with the rest of his theory of perception. (shrink)

This book offers a new definition of metaphor-as an ontological and visual construction, whose roots are external visual forms, and its motivation is our attachment to forms. This definition, which Michalle Gal names “visualist,” challenges the ruling conceptualist theory of metaphors and places a new emphasis on how we experience rather than understand metaphors. In doing so, she responds to the visual turn that is taking place in literature and the media, demanding that the visual (...) become a site of philosophical analysis. This focus on the external visual world allows Gal to employ visual theories to capture the essence of metaphor. She looks beyond conceptual or semantic mechanism, and returns to theories of Arnheim and Gombrich and the current evolution of ideas about the visual or material and embodied cognition. Proposing to see visual metaphors in their basic form, she uses a new externalist terminology of ontology, visuality, composition, affordance, construction, and emergence. Setting out a new theory that takes into account that humans are visual no less than cognitive creatures, Visual Metaphors and Aesthetics lays the foundation for a new vocabulary to talk about metaphors.

Perception is a first-person internal sensation induced within the nervous system at the time of arrival of sensory stimuli from objects in the environment. Lack of access to the first-person properties has limited viewing perception as an emergent property and it is currently being studied using third-person observed findings from various levels. One feasible approach to understand its mechanism is to build a hypothesis for the specific conditions and required circuit features of the nodal points where the mechanistic (...) operation of perception take place for one type of sensation in one species and to verify it for the presence of comparable circuit properties for perceiving a different sensation in a different species. The present work explains visual perception in mammalian nervous system from a first-person frame of reference and provides explanations for the homogeneity of perception of visual stimuli above flicker fusion frequency, the perception of objects at locations different from their actual position, the smooth pursuit and saccadic eye movements, the perception of object borders, and perception of pressure phosphenes. Using results from temporal resolution studies and the known details of visual cortical circuitry, explanations are provided for (a) the perception of rapidly changing visual stimuli, (b) how the perception of objects occurs in the correct orientation even though, according to the third-person view, activity from the visual stimulus reaches the cortices in an inverted manner and (c) the functional significance of well-conserved columnar organization of the visual cortex. A comparable circuitry detected in a different nervous system in a remote species-the olfactory circuitry of the fruit fly Drosophila melanogaster-provides an opportunity to explore circuit functions using genetic manipulations, which, along with high-resolution microscopic techniques and lipid membrane interaction studies, will be able to verify the structure-function details of the presented mechanism of perception.

This overview of the "sister arts" of the nineteenth century by younger scholars in art history, literature, and American studies presents a startling array of perspectives on the fundamental role played by images in culture and society. Drawing on the latest thinking about vision and visuality as well as on recent developments in literary theory and cultural studies, the contributors situate paintings, sculpture, monument art, and literary images within a variety of cultural contexts. The volume offers fresh and sometimes (...) extended discussions of single works as well as reevaluations of artistic and literary conventions and analyses of the economic, social, and technological forces that gave them shape and were influenced by them in turn. A wide range of figures are significantly reassessed, including the painters Charles Willson Peale, Washington Allston, Thomas Cole, George Caleb Bingham, Fitz Hugh Lane, and Mary Cassatt, and such writers as James Fenimore Cooper, Nathaniel Hawthorne, Henry David Thoreau, and William Dean Howells. One overarching theme to emerge is the development of an American national subjectivity as it interacted with the transformation of a culture dominated by religious values to one increasingly influenced by commercial imperatives. The essays probe the ways in which artists and writers responded to the changing conditions of the cultural milieu as it was mediated by such factors as class and gender, modes of perception and representation, and conflicting ideals and realities.

This is a book about how we see: the environment around us (its surfaces, their layout, and their colors and textures); where we are in the environment; whether or not we are moving and, if we are, where we are going; what things are good for; how to do things (to thread a needle or drive an automobile); or why things look as they do.The basic assumption is that vision depends on the eye which is connected to the brain. The (...) author suggests that natural vision depends on the eyes in the head on a body supported by the ground, the brain being only the central organ of a complete visual system. When no constraints are put on the visual system, people look around, walk up to something interesting and move around it so as to see it from all sides, and go from one vista to another. That is natural vision—and what this book is about. (shrink)

There is ample evidence from literature and clinical practice indicating mathematical difficulties in individuals with ADHD, even when there is no concomitant diagnosis of developmental dyscalculia. What factors underlie these difficulties is still an open question. Research on dyscalculia and neurotypical development suggests visual perception of numerosity (the number sense) as a building block for math learning. Participants with lower numerosity estimation thresholds (higher precision) are often those with higher math capabilities. Strangely, the role of numerosity (...) class='Hi'>perception in math skills in ADHD has been neglected, leaving open the question whether math difficulties in ADHD also originate from a deficitary visual number sense. In the current study we psychophysically measured numerosity thresholds and accuracy in a sample of children/adolescents with ADHD, but not concomitant dyscalculia (N = 20, 8–16 years). Math abilities were also measured by tasks indexing different mathematical competences. Numerosity performance and math scores were then compared to those obtained from an age-matched control group (N = 20). Bayesian statistics indicated no difference between ADHD and controls on numerosity perception, despite many of the symbolic math tasks being impaired in participants with ADHD. Moreover, the math deficits showed by the group with ADHD remained substantial even when numerosity thresholds were statistically regressed out. Overall, these results indicate that math difficulties in ADHD are unlikely to originate from an impaired visual number sense. (shrink)

Perception is not an independent, in‐the‐moment event. Instead, perceiving involves integrating prior expectations with current observations. How does this ability develop from infancy through adulthood? We examined how prior visual experience shapes visual perception in infants, children, and adults. Using an identical task across age groups, we exposed participants to pairs of colorful stimuli and implicitly measured their ability to discriminate relative saturation levels. Results showed that adult participants were biased by previously experienced exemplars, and exhibited (...) weakened in‐the‐moment discrimination between different levels of saturation. In contrast, infants and children showed less influence of memory in their perception, and they actually outperformed adults in discriminating between current levels of saturation. Our findings suggest that as humans develop, their perception relies more on prior experience and less on current observation. (shrink)

Global era is an era of acculturation which may surface difficulties due to the tendency of becoming global chaos that may influence people’s thought. Everyonehas their own views and has made changes with their own worldview perception; hybrid and heterodox. Changes without wisdom will eliminate local elements.This phenomenon has influenced myriad forms of visual composition and architecture of Bali Madya dwelling. Balinese culture has gone through various changes since Rsi Markandeya in the 9th century, Empu Kuturan in the (...) 10th century and Danghyang Nirartha in the 14th century. They changed many dwelling arrangements in architecture. Changes do not mean that one has to demolish the local indigenous elements but, instead, should attempt to develop various indigenous elements with the intention that the visual interior and architectural compositions have their own distinctive characters. In relation to that, aesthetic image and traditional space concept will be arranged in various kinds of acculturation in global visual forms. The dwelling space of Bali Madya concept was acculturated from the Bali Aga’s space concept during the era of Majapahit. This research is based on aesthetic and historical approach that stressed on the artistic aspects and design that are associated with aesthetic appeal. The analysis was done using observations of form and function including the meaning of space composition which was arranged to produce a proportionate composition with local images. (shrink)

PurposeThis study investigated the impact of age and myopia on visual form perception among Chinese school-age children.MethodsThis cross-sectional study included 1,074 students with a mean age of 12.1 ± 4.7 years. The mean spherical equivalence refraction of the participants was −1.45 ± 2.07 D. All participants underwent distance visual acuity, refraction measurement and local and global visual form perception test including orientation, parallelism, collinearity, holes and color discrimination tasks.ResultsThe reaction times of emmetropes were slower than (...) those of myopic and high myopic groups on both local and global discrimination tasks. A reduction in reaction times was found with increasing age on both local and global discrimination tasks. Age was significantly associated with both local and global visual perception performance after adjusting for gender, visual acuity and SER.ConclusionsThis study revealed that both local and global visual perception improve with age among Chinese children and that myopes seem to have better visual perception than emmetropes.

Visual culture can be considered from semiotic point of view as a system of visual codes. Several of them have natural routs. So the perceptual code is formed already on biological level mediating translation of sensory data into perceptual images of the spatial world. The means of natural perceptual code are transformed in culture, where they are involved in communication by depictions. The depiction on the flat performs the function of a “perceptogram”, which, on one hand, is an (...) external record of an internal perceptual image or an idea, and, on the other hand, serves as a program for a spectator’s visual perception. The means of this “perceptography” form an artificial code, which is, on the contrary to the perceptual code, communicative, deliberately used and transformed in various ways at different periods of time in diverse kinds of practical and artistic activity. Not all perceptograms become pieces of art, but all history of pictorial arts can be considered as a process of development and mastering with the different versions of this perceptographic code. The changes of this code in visual culture are connected with the intrinsic development of “vision forms” as well with invention of external means of communication. (shrink)

This thesis falls into two parts, a characterizing part, and an explanatory part. In the first part, I outline some of the core aspects of our ordinary understanding of visual perception, and how we regard it as a means of knowing. What explains the fact that I know that the lemon before me is yellow is my visual perception: I know that the lemon is yellow because I can see it. Some explanations of how one knows (...) specify that in virtue of which one genuinely knows, as opposed to merely believes, some content. Such explanations are epistemically satisfactory explanations. We think that visual perceptual explanations of knowledge can be epistemically satisfactory. I argue that that is what it is to regard visual perception as being among our means of knowing. In the second part, I explore how we might explain the fact that visual perception is a means of knowing (assuming that it is a fact). I ask what makes it the case that visual perception is a means of knowing (in the way we ordinarily think that it is)? I suggest that part of the answer to this question is that visual perception, given the nature it has, has a reason giving role. And that is just to say that the nature of visual perception is such that visually perceiving can ensure the satisfaction of some important condition on knowledge (namely, that if one knows that something is the case one must have a good reason to believe that it is the case). In concluding I suggest that giving this sort of explanation doesn't require a specific theory of perception. (shrink)
