The appearance of mass media and a versatile medium of videos can serve the convenience and instructive information for children; on the other hand, it could abet them in implicit image consumption. Now is the time for kids' to be in need of thinking power which enables them to make a choice, applications andcriticism of information within such visual cultures. In spite of these social changes, the realities are that our curriculum still doesn't meet a learner's demand properly. This (...) research, in this context, is aimed at looking out on the currently implemented art appreciation learning process in a critical fashion, and also aimed at suggesting a plan for visual culture learning by applying the philosophy program for kids as a new alternative. The purpose of such education is toenhance the capability to solve a variety of problems they are facing in the course of daily life by reflecting their matter of concern in a curriculum. What we have to pay attention to in visual culture learning is 'visual literacy.' Such an interpretative faculty of a critical reading of images is a must especially when kids should make a judgment of value hidden in images in their daily events, make an analysis of an ideological message and make an information-oriented decision. Therefore, learners have to enrich their higher-order thinking power as well as critical thinking faculty in modern society. If there is no objection to these social surroundings, it is quite natural that philosophy education, which forms a base of a higher-order thinking for children should be handled significantly at school.

Semantic networks were developed in cognitive science and artificial intelligence studies as graphical knowledge representation and inference tools emulating human thought processes. Formal analysis of the representation and inference capabilities of the networks modeled them as subsets of standard first-order logic (FOL), restricted in the operations allowed in order to ensure the tractability that seemed to characterize human reasoning capabilities. The graphical network representations were modeled as providing a visual language for the logic. Sub-sets of FOL targeted (...) on knowledge representation came to be called description logics, and research on these logics has focused on issues of tractability of subsets with differing representation capabilities, and on the implementation of practical inference systems achieving the best possible performance. Semantic network research has kept pace with these developments, providing visual languages for knowledge entry, editing, and presenting the results of inference, that translate unambiguously to the underlying description logics. This paper discusses the design issues for such semantic network formalisms, and illustrates them through detailed examples of significant generic knowledge structures analyzed in the literature, including determinables, contrast sets, genus/differentiae, taxonomies, faceted taxonomies, cluster concepts, family resemblances, graded concepts, frames, definitions, rules, rules with exceptions, essence and state assertions, opposites and contraries, relevance, and so on. Such examples provide important test material for any visual language formalism for logic. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Visual EmpireSusan Buck-Morss (bio)1 The Sovereign IconThe Question of SovereigntyJust when the nation-state appeared to be waning in significance, national sovereignty is back in the spotlight. The issue takes on special urgency in the United States, where sovereign right has been proclaimed persistently by the president in an attempt to justify policies of military aggression and violations of international and domestic law, executing these policies with disregard for (...) traditional judicial and constitutional procedures.1 Giorgio Agamben’s recently translated book State of Exception has touched off a small case of collective hysteria among American academics by claiming that by their intrinsic nature, democracies undermine themselves, that dictatorship is an ontological necessity of modern politics, and that the sovereign’s power to declare a state of emergency and with it a state exception to the law places potentially the whole world under the sign of the concentration camp.Agamben’s revelation, however, is not the scandal. It is a logical truism that something cannot be a member of its own set, that constituting power (pouvoir constituens) cannot be synonymous with constituted power (pouvoir constituent).Plato in the Timaeus described a self-eating, circular being as the first living thing in the universe–an immortal, perfectly constructed animal [image 1]. Agamben seems shocked to find that such an animal does not exist. If democracies could be self-constituting and self-reproducing, if they could realize the perfect closure of the Oroborus (snake consuming its tail), there would be no decay and no history—but also no hope, no escape from the magic circle of power that is capable of mystifying any political regime, no matter how democratically conceived. The historical event that ruptures the circle’s mythic repetition is also the possibility of a better future.Unlike both Walter Benjamin and Carl Schmitt, upon whom he relies, Agamben uses history ahistorically, in order to abstract from it a timeless ontology of power. In contrast, Benjamin is attentive to historical concreteness, as is Schmitt—this attention is their common bond. But when Benjamin criticizes the parliamentary democracy of the early Weimar Republic, it is not, as it is for Schmitt, out of yearning for a strong executive to cut through parliamentary legalism and compromise.2 Rather, it reminds twentieth-century [End Page 171] parliaments of their own violent origins. A present-day executive leader who, in using the emergency powers of his office, fails to be reminded of the historical origins of representative governments no longer feels It necessary to submit to democratic rule. Benjamin believed that the watered-down versions of democracy in his own time had become little more than bourgeois governing cliques, and for that reason, he might have appreciated Thomas Jefferson’s suggestion that every generation needs a new revolution. The sovereign who declares a state of exception would then be the citizens themselves.The question we need to ask is why Thomas Jefferson’s call for permanent revolution is not predictive of the history of democracies in modern times—why it is so difficult to cut off the head of the king so that it stays off, why popular sovereignty consistently resurrects an aura of quasi-mystical power around the sovereign figure—which since Hobbes’s Leviathan has been recognized as a human artifact, a merely mortal god [see image 2]. In a democracy where only the citizens have the legitimate right to declare a state of exception to the law, the real scandal occurs when an executive branch usurps that power and is allowed to get away with it.More than the sum of merely empirical individuals of which Hobbes’s Leviathan is composed, sovereignty is a transcendent category. The sovereign is an icon in the theological sense. He (or she) embodies an enigma—precisely the power of the collective to constitute itself. The sovereign figure as personification of the collective demonstrates the power of the visible image to close the circle between constituting and constituted power, explaining why even when the illegalities of an individual sovereign are exposed, the faith of the believer is still not shaken. As long as the circle appears closed, sovereign power remains intact; likewise, and... (shrink)

Visual cultures are being increasingly discussed in the history of science literature, although relatively very little of that work concerns the nuclear age. In addition, within the discrete yet bourgeoning literature on global nuclear art and culture, Oceania is often overlooked despite its central role in the development of the American, British, and French nuclear weapon capabilities, as well as their associated colonial legacies. This article serves to redress both concerns by examining the visual politics of Maralinga (...) in relation to settler-colonial and Aboriginal experiences, vulnerabilities and presentations. I do so by surveying artworks with a connection to the Australian experience of nuclear colonialism and find that the figure of biological life has been conspicuously left absent from contemporary non-Indigenous Australian depictions of British nuclear testing in Australia.

Ordinary human perceivers know that visual objects are perceivable from standpoints other than their own. The aim of this paper is to provide an explanation of how perceptual experience equips perceivers with this knowledge. I approach the task by discussing a variety of action-based theories of perception. Some of these theories maintain that standpoint transcendence is required for shape perception. I argue that this standpoint transcendence must take place in the phenomenal present and that it can be explained in (...) terms of the experience of perceivers who jointly attend to an object. Joint perceivers experience objects as being perceived from standpoints other than their own. They operate in what I call “social space”, in which they single out objects by triangulating targets’ locations relative to their co-perceivers’ standpoints on these targets. It is then possible to explain the public character of the objects of individual experience by appeal to what I call “public space”. This is a spatial framework whose locations are presented as standpoints whence joint attention to the target would ensue, were they occupied by co-perceivers. If shape perception requires standpoint transcendence, then shape perceivers operate in public space and are thus capable of singling out targets by triangulating their locations from standpoints other than their own. If it doesn’t, then the introduction of a public spatial framework is an additional step whose introduction explains how perceivers come to experience objects as perceivable from standpoints other than their own.

Incidence and prevalence rates of dengue have increased over the years, and the disease is quickly becoming cause for concern within the public health community. Globally, 128 countries and slightly under four billion people are at risk of contracting dengue. In Sri Lanka, more than half of dengue cases originate in Colombo, which in previous years, used a manual pen-and-paper data management system, which meant that it was not possible to obtain or provide up-to-date information about the severity and spread (...) of dengue. In 2015, two versions of a mobile application called Mo-Buzz Dengue were developed and launched in Colombo, Sri Lanka in order to overcome the challenges of the traditional management system by capitalizing on the rising affordability and ubiquity of mobile phone technology. To keep up with the dynamic nature of disease outbreaks, real-time data need to be visualized in a manner which facilitates discerning and comprehending these patterns. Hence, we used health maps in Mo-Buzz to effectively present this information. The first version of Mo-Buzz was for public health inspectors, digitized data management as well as provided educational materials. The second version of Mo-Buzz was a source of information for the general public, a crowdsourcing platform to provide information relating to dengue transmission, and for health authorities to alert users to dengue-specific developments in their area. This paper illustrates the design considerations of the Mo-Buzz disease surveillance system for the general public. A draft scaled-down version of the PHI system was used to obtain feedback and make incremental design enhancements. Additionally, similar health maps were evaluated in terms of capability and usability. These findings were applied to identify future enhancements to the health map of Mo-Buzz Dengue. (shrink)

The habit of separating the intuitive from the abstractive functions, as they were called in the Middle Ages, goes far back in our tradition. Descartes, in the sixth Meditation, defined man as "a thing that thinks," to which reasoning came naturally; whereas imagining, the activity of the senses, required a special effort and was in no way necessary to the human nature or essence. The passive ability to receive images of sensory things, said Descartes, would be useless if there did (...) not exist in the mind a further and higher active faculty capable of shaping these images and of correcting the errors that derive from sensory experience. A century later Leibnitz spoke of two levels of clear cognition.1 Reasoning was cognition of the higher degree: it was distinct, that is, it could analyze things into their components. Sensory experience, on the other hand, was cognition of the lower order: it also could be clear but it was confused, in the original Latin sense of the term; that is, all elements fused and mingled together in an indivisible whole. Thus artists, who rely on this inferior faculty, are good judges of works of art but when asked what is wrong with a particular piece that displeases them can only reply that it lacks nescio quid, a certain "I don't know what." · 1. Leibnitz, Nouveaux essais sur l'entendement humain , bk. 2, chap. 29.

John Venn and Charles L. Dodgson (Lewis Carroll) created systems of logic diagrams capable of representing classes (sets) and their relations in the form of propositions. Each is a proof method for syllogisms, and Carroll's is a sound and complete system. For a large number of sets, Carroll diagrams are easier to draw because of their self-similarity and algorithmic construction. This regularity makes it easier to locate and thereby to erase cells corresponding with classes destroyed by the premises of an (...) argument, a particularly difficult task in Venn diagrams for more than four sets. Carroll diagrams can represent existential propositions easily, so they are capable of clearly representing more complex problems than Venn's system can. Finally, both Carroll and Venn diagrams are maximal, in the sense that no additional logic information like inclusive disjunctions is able to be represented by them. Carroll's logic diagrams and logic trees constitute his visual logic system. (shrink)

Auditory-guided vocal learning is a mechanism that operates both in humans and other animal species making us capable to imitate arbitrary sounds. Both auditory memories and auditory feedback interact to guide vocal learning. This may explain why it is easier for humans to imitate the pitch of a human voice than the pitch of a synthesized sound. In this study, we compared the effects of two different feedback modalities in learning pitch-matching abilities using a synthesized pure tone in 47 participants (...) with no prior music experience. Participants were divided into three groups: a feedback group receiving real-time visual feedback of their pitch as well as knowledge of results; an equal-timbre group receiving additional auditory feedback of the target note with a similar timbre to the instrument being used ; and a control group practicing without any feedback or knowledge of results. An additional fourth group of violin experts performed the same task for comparative purposes. All groups were posteriorly evaluated in a transfer phase. Both experimental groups improved their intonation abilities with the synthesized sound after receiving feedback. Participants from the equal-timber group seemed as capable as the feedback group of producing the required pitch with the voice after listening to the human voice, but not with the violin. In addition, only participants receiving real-time visual feedback learned and retained in the transfer phase the mapping between the synthesized pitch and its correspondence with the produced vocal or violin pitch. It is suggested that both the effect of an objective external reward, together with the experience of exploring the pitch space with their instrument in an explicit manner, helped participants to understand how to control their pitch production, strengthening their schemas, and favoring retention.

This paper addresses the question of whether a general method is capable of accommodating the vast array of contexts in which art objects are studied. I propose a framework for such a general method, which is, however, limited to a specific research task: reconstructing the circumstances under which a culturally and/or temporally distant or “exotic” art object becomes interesting (or menacing) to look at. The proposed framework is applied to evaluate Anthony Forge’s essays on the visual art of the (...) Abelam. The essays played a central role in the rekindling of anthropological interest in visual art, but they have also been subject to criticism for forcing on Abelam art Western categories that distort the role art objects play in the Abelam world. Assessing the corpus in terms of the proposed framework allows me to exemplify the main differences between a pragmatic and a semantic approach to gaining access to the efficacy of culturally or temporally distant art.

In Remarks on the philosophy of psychology Wittgenstein uses ambiguous illusions to investigate the problematic relation of perception and interpretation. I use this problem as a starting point for developing a conceptual framework capable of expressing problems associated with visual perception in a precise manner. I do this by discerning between subjective and objective meaning of the term “to see” and by specifying the beliefs which are to be ascribed to the observer when we assert that she sees a (...) given object. The framework (detailed in section 2) is then used to analyze the case of the duck/rabbit illusion. It shows that ambiguous illusions present us with a specific skeptical challenge but that the challenge can be overcome by empirical sciences. Along the way I explicate some of the common notions associated with perception (“to look at”, “to have an impression of…”, "to react as if one had an impression of..”, “to convince oneself that what one sees is…”).

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)

We show that cast shadows can have a significant influence on the speed of visual search. In particular, we find that search based on the shape of a region is affected when the region is darker than the background and corresponds to a shadow formed by lighting from above. Results support the proposal that an early-level system rapidly identifies regions as shadows and then discounts them, making their shapes more difficult to access. Several constraints used by this system are (...) mapped out, including constraints on the luminance and texture of the shadow region, and on the nature of the item casting the shadow. Among other things, this system is found to distinguish between line elements (items containing only edges) and surface elements (items containing visible surfaces), with only the latter deemed capable of casting a shadow.

Humans have been shown capable of performing many cognitive tasks using information of which they are not consciously aware. This raises questions about what role consciousness actually plays in cognition. Here, we explored whether participants can learn cue-target contingencies in an attentional learning task when the cues were presented below the level of conscious awareness, and how this differs from learning about conscious cues. Participants’ manual (Experiment 1) and saccadic (Experiment 2) response speeds were influenced by both conscious and unconscious (...) cues. However, participants were only able to adapt to reversals of the cue-target contingencies (Experiment 1) or changes in the reliability of the cues (Experiment 2) when consciously aware of the cues. Therefore, although visual cues can be processed unconsciously, learning about cues over a few trials requires conscious awareness of them. Finally, we discuss implications for cognitive theories of consciousness. (shrink)

Standard models of visual perception hold that vision is an inferential or interpretative process. Such models are said to be superior to competing, non-inferential views in explanatory power. In particular, they are said to be capable of explaining a number of otherwise mysterious, visual phenomena such as multi-stable perception. Multi-stable perception paradigmatically occurs in the presence of ambiguous figures, single images that can give rise to two or more distinct percepts. Different interpretations are said to produce the different (...) percepts. In this paper, I argue that a non-inferential account of visual perception is just as capable of explaining multi-stable perception. I propose an embedded understanding of vision, and show how the embedded account can, after properly qualifying them, use the explanatory resources of the inferential view to explain just what such a view explains.

Our visual system not only mediates information about the visual environment but is capable of generating pictures of nonexistent worlds: afterimages, illusions, phosphenes, etc. We are ''aware'' of these pictures just as we are aware of the images of natural, physical objects. This raises the question: is the neural correlate of consciousness (NCC) of such images the same as that of images of physical objects? Images of natural objects have some properties in common with afterimages (e.g., stability of (...) verticality) but there are also obvious differences (e.g., images maintain size constancy, whereas afterimages follow Emmert's Law: when seen while screens at different distances are observed, an afterimage looks larger, the greater the distance of the screen). The differences can be explained by differences in the retinal extent of images and afterimages, which favors the view that both have the same NCC. It seems reasonable to assume that before neural activity can produce awareness, all the computations necessary for a veridical representation of, e.g., an object, must be completed within the neural substrate and that information characteristic of a particular object must be available within the NCC. Given these assumptions, it can be shown that no retinotopic (in a strict sense) cortical areas can serve as the NCC, although some type of topographic representation is necessary. It seems also to be unlikely that neurons classified as cardinal cells alone can serve as NCC. (shrink)

The idea that looking at a photograph is akin to face-to-face perception and that photographs provide genuine perceptual access to the objects they depict was notoriously defended by Kendall Walton in “Transparent Pictures.” Walton’s main thesis is that photographs are transparent in the sense that we can see objects through them. The main goal of this article is to support Walton’s view by providing a full account of photographic transparency. I will argue that the transparency that characterizes photography is not (...) metaphorical but in fact exhibits all the essential properties of transparent materials. To understand how a photograph can be transparent, one must understand the special type of causal connection between a photograph and what it shows. Building on Fritz Heider’s work, I will argue that photography is a visual medium, like air, water, glass, or mirrors, capable of transmitting the visual properties of distant objects to the perceiver.

Casting a glance at philosophical inquiries of the last decades, with regard to human cognition (in a broad sense), we are witnesses to turns one after the other. The settings were based on the change of scope and perspective of investigations. The so-called linguistic turn refers to “the view that philosophical problems are problems which may be solved (or dissolved) either by reforming language or by understanding more about the language we presently use”. In the 90s, W. J. T. Mitchell (...) coined the phrase pictorial turn, calling attention to the fact that “pictures form a point of peculiar friction and discomfort across a broad range of intellectual inquiry”. In order to eliminate this intellectual discomfort, Mitchell considers exploratory and explicatory approaches that focus on non-linguistic symbol systems and do not consider language as the only source of a significant paradigm regarding meaning. Recently, there has been a shift of emphasis regarding the basis of cognitive skills. This may be the next turn, a sensorimotor or activist one. Although this turn has massive roots in the past, and there is some controversy regarding whether it is fully reconcilable with various findings of cognitive neurology, this view seems to be capable of providing a framework within which the verbalist approach can cease to be the dominant view.

Influences on the perception of affordances (i.e., opportunities for actions) have been primarily studied by manipulating the functional morphology of the body. However, affordances are not just determined by the functional morphology of the perceiver, but also by the physiological state of the perceiver. States of anxiety have been shown to lead to marked changes in individuals’ physiological state and their behaviour. To assess the influence of emotional state on affordance perception, the perception of action capabilities in near space (...) was examined after participants completed an anxiety-provoking task. Anxiety was induced immediately prior to tasks that assessed participants' perceived reaching ability in Experiment 1, grasping ability in Experiment 2, and the ability to pass their hands through apertures in Experiment 3. Results indicated that those participants who experienced changes in anxiety underestimated their reaching, grasping, and passing ability compared to non-anxious participants. In other words, anxious participants were more conservative in their estimations of their action capabilities. These results suggest that anxiety influences the perception for affordances in near space and are consistent with the notion that anxiety induces withdrawal behaviours. (shrink)

Computational visual perception, also known as computer vision, is a field of artificial intelligence that enables computers to process digital images and videos in a similar way as biological vision does. It involves methods to be developed to replicate the capabilities of biological vision. The computer vision’s goal is to surpass the capabilities of biological vision in extracting useful information from visual data. The massive data generated today is one of the driving factors for the tremendous (...) growth of computer vision. This survey incorporates an overview of existing applications of deep learning in computational visual perception. The survey explores various deep learning techniques adapted to solve computer vision problems using deep convolutional neural networks and deep generative adversarial networks. The pitfalls of deep learning and their solutions are briefly discussed. The solutions discussed were dropout and augmentation. The results show that there is a significant improvement in the accuracy using dropout and data augmentation. Deep convolutional neural networks’ applications, namely, image classification, localization and detection, document analysis, and speech recognition, are discussed in detail. In-depth analysis of deep generative adversarial network applications, namely, image-to-image translation, image denoising, face aging, and facial attribute editing, is done. The deep generative adversarial network is unsupervised learning, but adding a certain number of labels in practical applications can improve its generating ability. However, it is challenging to acquire many data labels, but a small number of data labels can be acquired. Therefore, combining semisupervised learning and generative adversarial networks is one of the future directions. This article surveys the recent developments in this direction and provides a critical review of the related significant aspects, investigates the current opportunities and future challenges in all the emerging domains, and discusses the current opportunities in many emerging fields such as handwriting recognition, semantic mapping, webcam-based eye trackers, lumen center detection, query-by-string word, intermittently closed and open lakes and lagoons, and landslides.

In this paper, a new method of quantitatively assessing continuity and discontinuity of visual attention is developed. The method is based on representing narrative information using graph theory. It is applicable to any type of narrative report. Since dream reports are often described as bizarre, and since bizarreness is partially characterized by discontinuities in plot, we chose to test our method on a set of dream data. Using specific criteria for identifying and arranging objects of visual attention, dream (...) narratives from 10 subjects were obtained and mapped onto graphs. The interrater reliabilities were 76% and 91% . Discontinuities in visual attention were quantified by plotting transitions from one part of a graph to another, which provided a spatiotemporal map of attention shifts within a narrative. This procedure was compared with other approaches to discontinuity and also applied to a set of 10 fantasy reports from the same subjects. The results showed that our method includes but transcends other approaches and has the capability to distinguish dream and fantasy reports. To our knowledge, the method provides the most rigorous and reliable measure to date of continuity and discontinuity of attention in narrative reports. (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 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)

: Faraday is often described as an experimentalist, but his work is a dialectical interplay of concrete objects, visual images, abstract, theoretically-informed visual models and metaphysical precepts. From phenomena described in terms of patterns formed by lines of force he created a general explanation of space-filling systems of force which obey both empirical laws and principles of conservation and economy. I argue that Faraday's articulation of situated experience via visual models into a theory capable of verbal expression (...) owed much to his strategy of moving—via conjectural visual models—between the phenomenology of particulars (often displayed as patterns) and the general features of dynamical phenomena which he depicted as structures.

One of the best known arguments against the connectionist approach to artificial intelligence and cognitive science is that neural networks are black boxes, i.e., there is no understandable account of their operation. This difficulty has impeded efforts to explain how categories arise from raw sensory data. Moreover, it has complicated investigation about the role of symbols and language in cognition. This state of things has been radically changed by recent experimental findings in artificial deep learning research. Two kinds of artificial (...) deep learning networks, namely the convolutional neural network and the generative adversarial network have been found to possess the capability to build internal states that are interpreted by humans as complex visual categories, without any specific hints or any grammatical processing. This emergent ability suggests that those categories do not depend on human knowledge or the syntactic structure of language, while they do rely on their visual context. This supports a mild form of empiricism, while it does not assume that computational functionalism is true. Some consequences are extracted regarding the debate about amodal and grounded representations in the human brain. Furthermore, new avenues for research on cognitive science are open. (shrink)

There is a widely held view that visual representations (images) do not depict negation, for example, as expressed by the sentence, “the train is not coming.” The present study focuses on the real-world visual representations of photographs and comic (manga) illustrations and empirically challenges the question of whether humans and machines, that is, modern deep neural networks, can recognize visual representations as expressing negation. By collecting data on the captions humans gave to images and analyzing the occurrences (...) of negation phrases, we show some evidence that humans recognize certain images as expressing negation. Furthermore, based on this finding, we examined whether or not humans and machines can classify novel images as expressing negation. The humans were able to correctly classify images to some extent, as expected from the analysis of the image captions. On the other hand, the machine learning model of image processing was only able to perform this classification at about the chance level, not at the same level of performance as the human. Based on these results, we discuss what makes humans capable of recognizing negation in visual representations, highlighting the role of the background commonsense knowledge that humans can exploit. Comparing human and machine learning performances suggests new ways to understand human cognitive abilities and to build artificial intelligence systems with more human-like abilities to understand logical concepts.

This article is first within the Russian and Western art history to examine the concept of visual poetics as a separate subject of research. Based on the analysis of iconographic and theoretical searches of the masters of symbolism, which found reflection within the boundaries of expressive means of visual art, the author comes concludes on the poetic principles of symbolist artists as the fundamental sources of the formation of the style of Art Nouveau – a new sculptural language (...) of the XIX – early XX centuries. Detail characteristic of the philosophical-aesthetic content that underlies optical forms of the visual symbolist image, in its scientific origins leans on the capabilities of the art comparative-formal analysis, as well as iconological method adapted to the period under review. The innovative conceptual approach towards studying the art of symbolism lies in the fact that poetry as the concept is depicted beyond the literary sphere, as a specific type of artistic worldview that influenced the development of the visual language of art in the era of Art Nouveau. At the same time, visual poetics is compared to the complex system of internal images, which shape in with the works of the master throughout the entire path of his self-expression, and are directly related to profoundness of the poetic principle of the soul, lyrical and metaphorical intuition of the artist. This approach allows us broadening the representation on the aesthetic benchmarks of the symbolist artists, as well as designating the new methodological coordinates in the field of studying the art of symbolism in both national and international contexts.

What does it mean to communicate with visual messages and to convey ideas with the help of images? Is the visual sign capable of substituting the subject when he or she is not present? Can it be relied upon in communication? Can it happen that a gap between the subject’s visual image and identity becomes an insurmountable barrier on the way to understanding? This paper attempts to discover visuality as a weighty addition to the spoken word, to (...) reconsider its role in communication so that it is treated not as a deceptive simulacrum but a representation of the subject in dialogical space, an embodiment of an eternal pure impulse, an aspiration to unfold oneself in front of the other.

Helen Neville has gathered ERP data suggesting that accessing an “implicit” memory system produces a qualitatively different kind of ERP wave than does accessing our “explicit” conscious memory system. These results corroborate the hypothesis that an early anterior priming effect indexes activity of a system specialized for words, while a later posterior priming effect indexes access to general, episodic representations of words. Moreover, she saw no effects in the masked paradigms using pseudo-words, further supporting the notion of an early lexicon. (...) However, we might not see any effects because the tasks use stimuli too complicated for an early automatic system to encode rapidly. Hence, masked priming effects for novel stimuli might be seen immediately with very simple input patterns. The following series of experiments was designed to test this hypothesis, as well as to try to differentiate the supposed early lexicon from other sorts of early access memory systems and to characterize more fully the capabilities of these early systems. In particular, ERP waveforms are compared for unmasked and masked priming conditions using simple 5-line visual patterns in experiments requiring subjects to make rapid decisions concerning the physical structure of the shapes.

Multiple versions of the Chinese Remote Associates Test have been developed. Thus far, all CRATs have employed verbal stimuli; other forms of stimuli have not yet been used. In this context, the present study compiled a Chinese Visual Remote Associates Test that conforms to the Chinese language and culture based on a picture naming database. The developed CVRAT has two versions, CVRAT-A and CVRAT-B, each comprising 20 test questions. A typical CVRAT question consists of three stimuli pictures, requiring respondents (...) to propose a target word that is semantically associated with all the pictures. When compiling the CVRAT, this study first selected target words, sifted through stimuli words and corresponding pictures, and analyzed pilot test questions. After compilation, their reliability and validity were examined. The results showed that the CVRAT had moderate internal consistency reliability, good criterion-related validity for the Chinese Word Remote Associates Test, Chinese Radical Remote Associates Test, Chinese Compound Remote Associates Test, insight problem-solving, as well as acceptable discriminant validity for fluency, flexibility, and originality of a divergent thinking test. In other words, CVRAT can effectively measure remote associative capability and provides a figural creativity test that facilitates the understanding of different kinds of remote associations.

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.

Humans are capable of extracting recurring patterns from their environment via statistical learning (SL), an ability thought to play an important role in language learning and learning more generally. While much work has examined statistical learning in infants and adults, less work has looked at the developmental trajectory of SL during childhood to see whether it is fully developed in infancy or improves with age, like many other cognitive abilities. A recent study showed modality‐based differences in the effect of age (...) during childhood: While visual SL improved with age, auditory SL did not. This finding was taken as evidence for modality‐based differences in SL. However, since that study used auditory linguistic stimuli (syllables), the differential effect of age may have been driven by stimulus type (linguistic vs. non‐linguistic) rather than modality. Here, we ask whether age will affect performance similarly in the two modalities when non‐linguistic auditory stimuli are used (familiar sounds instead of syllables). We conduct a large‐scale study of children's performance on visual and non‐linguistic auditory SL during childhood (ages 5–12 years). The results show a similar effect of age in both modalities: Unlike previous findings, both visual and non‐linguistic auditory SL improved with age. These findings highlight the stimuli‐sensitive nature of SL and suggest that modality‐based differences may be stimuli‐dependent, and that age‐invariance may be limited to linguistic stimuli.

This article discusses several key issues concerning the study of attention and its relation to visual perception, with an emphasis on behavioral and experiential aspects. It begins with an overview of several classical works carried out in the latter half of the 20th century, such as the development of early filter and spotlight models of attention. This is followed by a survey of subsequent research that extended or modified these results in significant ways. It covers current work on various (...) forms of induced blindness and on the capabilities of nonattentional processes. It also includes proposals about how a "just-in-time" allocation of attention can create the impression that we see our surroundings in coherent detail everywhere, as well as how the failure of such allocation can result in various perceptual deficits. The final section examines issues that have received little consideration to date, but may be important for new lines of research in the near future. These include the prospects for a better characterization of attention, the possibility of more systematic explanations, factors that may significantly modulate attentional operation, and the possibility of several kinds of visual attention and visual experience.

This article proposes a semio-rhetorical epistemology for visual documents, one capable of accounting for both their internal configuration, which we shall call the compositional dimension, and their persuasive force within public space, or their rhetorical dimension. The field of reference will be that of identity-related images on social networks, because compared to other kinds of images, such as artistic or professional ones, they adopt new compositional solutions and new dynamics of circulation. To test this theoretical framework, we will conduct (...) an analysis which has never been carried out in semiotics and which, as far as we know, remains very rare even in the overall field of visual studies, that is, the analysis of the profile of an Instagram influencer’s visual production, that of Canadian artist Rupi Kaur. Taking into account the flow of images shared over time, we will focus primarily on the compositional dimension that articulates the specificity of the language of images. The most appropriate model for investigating social network photos seems to be that of the portrait, thanks to which we will identify a first series of regularities and deviations. Secondly, we will turn towards the rhetorical dimension – the persuasive strategies found within, through, and towards images – focusing on the analysis of a single photo: on the one hand, it is a shot which presents greater compositional richness than others; on the other hand, it has greatly impacted the notoriety of the influencer, due to the censorship incurred on Instagram, its abundant coverage by traditional media, and the heated debate it triggered on social media. We will thus propose a reinterpretation of Paul Ricœur’s theory of identity in order to balance the rhetorical and the compositional dimensions through a unitary theoretical hypothesis. Visual identity on social networks is always the result of a negotiation between two opposite tendencies: on the one hand, the experiential pressure expressed through images related to the body and everyday practices; on the other, the algorithmic pressure due to the delegation of the management of identity to software. The case of Rupi Kaur is a rare example of a critical mediation between these two pressures and helps us build a methodology for the examination of images belonging to other social domains. (shrink)

We attribute the capability of imagination to the madman as to the scientist, to the novelist as to the metaphysician, and last but not least to ourselves. The same, apparently, holds for thought experimentation. Ernst Mach was the first to draw an explicit link between these two mental acts; moreover -in his perspective- imagination plays a pivotal role in thought experimentation. Nonetheless, it is not clear what kind of imagination emerges from Mach’s writings. Indeed, heated debates among cognitive scientists and (...) philosophers turn on the key distinction between sensory and cognitive imagination. Generally speaking, we can say that sensory imagination shares some processes with perception, cognitive imagination with the formation of belief. Both the vocabulary used in the literature on thought experiments and what I refer to as “Machian tradition” indicate imagination as a notion of central importance in the reasoning involved in thought experiments. However, most authors have really focused on sensory (in particular, visual) imagination, but have neglected the second kind. Moreover, some authors attribute to Mach the idea that it is visual imagery that is primarily at work in thought experiments. I claim another interpretation is possible, according to which Mach can be said to deal with cognitive imagination. The main aim of this paper is to retrace Mach’s original arguments and establish a connection with the cognitive literature on imagination. I will argue that imagination tout court could play a role in thought experimentation. Once imagination is seen as the key to the “cognitive black-box” of the thought experiment, we will have moved a step closer to a simulative imagining-based account of thought experimentation.

The article examines the place of graphic design in modern post-industrial society, extending beyond purely applied art and aspiring to play the role of an expert in the interiors of human existence, determining the social and cultural status of an individual. It is argued that graphic design, organically integrating into contexts and actively responding to the challenges of such a social-decorative phenomenon as fashion, plays a significant role in shaping taste culture. This attests to the multiplicity of ambivalent cultural manifestations (...) of graphic design. Special attention is given to identifying the functional potential of graphic design in creating cross-cutting trends that, through non-verbal means of communication, can form and maintain social and cultural unity. In connection with this, an analysis of graphic design is carried out through the prism of philosophical communication, allowing the identification of graphic design as the most effective practice of nonverbal communication and information visualization in post-industrial society. It is determined that graphic design is capable not only of generating new meanings but also of creating communicative gaps. Given this specificity, the article particularly focuses on identifying the educational and upbringing potential of graphic design. It is demonstrated that the process of creating visual images and their subsequent interpretation by consumers of graphic information depends not only on the aesthetic taste, ethical beliefs, and humanistic orientation of the designer (visualizer) but also on their educational and upbringing potential. The necessity of strengthening humanistic orientations in modern Ukrainian design and art education is emphasized. (shrink)

Individuals with Down syndrome (DS) are widely believed to possess considerable socialization strengths. However, the findings on social cognition capabilities are controversial. In the present study, we investigated whether individuals with DS exhibit shortage in face tuning, one of the indispensable components of social cognition. For this purpose, we implemented a recently developed Face-n-Food paradigm with food-plate images composed of food ingredients such as fruits and vegetables. The key benefit of such ‘face like non-face’ images is that single elements (...) do not facilitate face processing. In a spontaneous recognition task, 25 children with DS aged 9 to 18 years were presented with a set of Face-n-Food images bordering on the Giuseppe Arcimboldo style. The set of images was administered in a predetermined order from the least to most resembling a face. In DS individuals, thresholds for recognition of the Face-n-Food images as a face were drastically higher as compared not only with typically developing controls, but also with individuals with autistic spectrum disorders and Williams-Beuren syndrome. This outcome represents a significant step towards better conceptualization of visual social world in DS and neurodevelopmental disorders in general. (shrink)

The core objective of this article is to advocate for the cultivation of philosophical thinking, a pivotal element that fosters a profound understanding of the evolutionary trajectory of the information society and the human role within this paradigm. An examination of the unique attributes of the information-communicative educational space, coupled with the tenets of post-classical knowledge, underscores the imperative for nurturing human capabilities and personality traits essential for efficacious self-identification within the information society. The anthropological nature of philosophy focuses (...) on understanding that rational, abstract-universal, theoretical thinking is fundamentally value-laden, not free from human interests. These interests determine the directions of scientific research and, if necessary, limit freedom of choice. The philosophical perception of communication, seen as a wellspring of new knowledge generation aimed at pragmatic problem-solving and emerging from human solidarity, promotes the cultivation of creativity, an intrinsic quality of the persona. A favorable factor for the successful development of dialogical thinking is the transformation of the previously dominant written culture into an oral one, where natural spoken language plays an increasingly important role. The exigency for a high degree of personal individualization and thought individualization, prerequisites for successful self-identification, calls for the fostering of stereoscopic and pluralistic thinking. Such thinking, inherent to the philosophical discourse, inherently possesses an authorial essence and proffers diverse interpretative responses to identical queries, thereby catalyzing the development of contextual thinking adept at unraveling the meaning of events in situational contexts. Globalization, accompanied by an increase in the world’s diversity, contributes to the development of global thinking – the ability to solve local problems considering global patterns. As a counterbalance to informational pluralism, the visual turn emerges, epitomized by the capacity to encapsulate voluminous data into intricate montaged images and to adeptly interpret such constructs. This paradigm shift necessitates the enhancement of visual thinking, which, as contemporary philosophy posits, is oriented toward assimilating social experience, laying the groundwork for self-identification. The presented arguments substantiate the conviction that the development of philosophical thinking in the educational process is not an auxiliary factor, but an imperative of the modern information society.

This paper is about visual narratives. Most of the examples used in the philosophical literature on narratives are literary ones. But a general account of narrative needs to be able to cover both pictorial and literary cases. In the first part of the paper, I will argue that none of the most influential accounts of narrative are capable of this. In the second part, I outline an account of visual narratives, or, rather, of our engagement with visual (...) narratives. (shrink)

Humans naturally perceive visual patterns in a global manner and are remarkably capable of extracting object shapes based on properties such as proximity, closure, symmetry, and good continuation. Notwithstanding the role of these properties in perceptual grouping, studies highlighted differences in disembedding performance across individuals, which are summarized by the field dependence dimension. Evidence suggests that age and educational attainment explain part of this variability, whereas the role of sex is still highly debated. Also, which stimulus features primarily influence (...) inter-individual variations in perceptual grouping has still to be fully determined. Building upon these premises, we assessed the role of age, education level, and sex on performance at the Leuven Embedded Figure Test—a proxy of disembedding abilities—in 391 cisgender individuals. We also investigated to what extent shape symmetry, closure, complexity, and continuation relate to task accuracy. Overall, target asymmetry, closure, and good continuation with the embedding context increase task difficulty. Simpler shapes are more difficult to detect than those with more lines, yet context complexity impairs the recognition of complex targets to a greater extent. Concerning demographic data, we confirm that age and educational attainment are significantly associated with disembedding abilities and reveal a perceptual advantage in males. In summary, our study further highlights the role of shape properties in disembedding performance and unveils sex differences not reported so far. (shrink)

The human visual system is capable of learning both abstract and specific mappings to underlie shape recognition. How could dissimilar shapes be mapped to the same location in visual representation space, yet similar shapes be mapped to different locations? Without fundamental changes, Chorus, like other single-system models, could not accomplish both mappings in a manner that accounts for recent evidence.

Our understanding of human visual perception generally rests on the assumption that conscious visual states represent the interaction of spatial structures in the environment and our nervous system. This assumption is questioned by circumstances where conscious visual states can be triggered by external stimulation which is not primarily spatially defined. Here, subjective colors and forms are evoked by flickering light while the precise nature of those experiences varies over flicker frequency and phase. What’s more, the occurrence of (...) one subjective experience appears to be associated with the occurrence of others. While these data indicate that conscious visual experience may be evoked directly by particular variations in the flow of spatially unstructured light over time, it must be assumed that the systems responsible are essentially temporal in character and capable of representing a variety of visual forms and colors, coded in different frequencies or at different phases of the same processing rhythm.

Husserl’s lifelong interest in Kant eventually becomes a preoccupation in his later years when he finds his phenomenology in competition with Neokantianism for the title of transcendental philosophy. Some issues that Husserl is concerned with in Kant are bound up with the works of Lambert. Kant believed that the role played by principles of sensibility in metaphysics should be determined by a “general phenomenology” on which Lambert had written. Kant initially believed that man is capable only of symbolic cognition, not (...) intellectual intuition. Lambert saw an increasing need in mathematics for symbolic cognition as exemplified in his proofs of the irrationality of π and e. Kant takes from Leibniz and Lambert an unrestricted notion of construction, allowing him to view mathematics as constructing its concepts in intuition, while Lambert’s proofs convince him that all mathematical problems are eventually solvable. Husserl criticizes Kant’s intuitionism for its inadequate accommodation of meaning to intuition, which he redresses with his theory of categorial intuition. This may improve on Kant’s intuition of the axiom of parallels but not so clearly on his spatial intuition. Husserl opposes Kant’s view of space as the form of outer intuition with his own view of it as the form of things. Husserl’s exploration of the geometry of visual space, which involves his earliest uses of epoché and reduction, converges however with Hilbert’s logical analysis of Kantian spatial intuition in leading to Euclidean spatial judgments. Hilbert’s analysis leads him to affirm the solvability of all well posed mathematical problems, a thesis complicated by the outbreak of logical paradoxes. Untroubled by such paradoxes, Husserl develops a supramathematics of all possible deductive systems whose completeness implicitly would also provide solutions of all such problems. Husserl’s full transcendental turn coincides with his realization that in effecting his Copernican turn, Kant was really the first to detect the “secret longing” of modern philosophy for a phenomenological clarification of being. Husserl now finds that Kant’s transcendental deductions presuppose a pure ego not adequately analyzed by Kant that survives the phenomenological reduction. Husserl’s idealism leads him to develop his own intuitionism, which adds to Kant’s, a “method of clarification” of mathematical concepts intended to clarify difficult impossibility proofs, but neither Husserl nor Kant base arithmetic on time. Husserl’s critique of the room left in Kant’s idealism, for things in themselves, leads to his own monadological solution of the problem of intersubjectivity. Husserl’s final judgment on Kant is that his form of transcendental idealism did not enable him to achieve absolute subjectivity through a genuine transcendental reduction. (shrink)

What is photography? Is it primarily a source of knowledge about the world or an art? Many have said the former, because it records the world automatically, others the latter because it embodies human subjectivity. Can it photography be both or must we choose? In _On Photography: A Philosophical Inquiry_ Diarmuid Costello examines these fascinating questions and more. In so doing he introduces some of the fundamental topics and debates about the nature of photography, with the help of photographic images (...) from Paul Strand, Lee Friedlander, James Welling, Jeff Wall, and Gerhard Richter, among others. Tracing the roots of thinking about photography from its discovery, through nineteenth-century debates about its standing as art, to twentieth-century Modernism and post-War cultural criticism, Costello identifies the emergence of a powerful "orthodox" view of photography. The features that make photographs compelling documents are precisely those that put pressure on its standing as art; though they provide a wealth of empirical information, they cannot have the unifying vision we look for in art. He draws on the reflections of photographers and theorists, including Paul Strand, Edward Weston, Laszlo Moholy-Nagy, Siegfried Kracauer, Andre Bazin and Stanley Cavell to illustrate this fundamental tension. The view comes to fruition in the work of Roger Scruton and Kendall Walton. Whether pure photography is capable of representing fictions, or always presents a transparent window onto the real world becomes the key question. Recently, the orthodox view has come under increasing pressure from a new generation of philosophers who reject the contrast between machine and hand made images that underwrites it. He concludes by examining photographic agency in a digital age. Written in a clear and engaging style, _On Photography: A Philosophical Inquiry_ is essential reading for anyone interested in the philosophy of photography, aesthetics, art, and visual studies.

The paper addresses the capabilities and limitations of extrafoveal processing during a categorical visual search. Previous research has established that a target could be identified from the very first or without any saccade, suggesting that extrafoveal perception is necessarily involved. However, the limits in complexity defining the processed information are still not clear. We performed four experiments with a gradual increase of stimuli complexity to determine the role of extrafoveal processing in searching for the categorically defined geometric shape. (...) The series of experiments demonstrated a significant role of extrafoveal processing while searching for simple two‐dimensional shapes and its gradual decrease in a condition with more complicated three‐dimensional shapes. The factors of objects’ spatial orientation and distractor homogeneity significantly influenced both reaction time and the number of saccades required to identify a categorically defined target. An analysis of the individual p‐value distributions revealed pronounced individual differences in using extrafoveal analysis and allowed examination of the performance of each particular participant. The condition with the forced prohibition of eye movements enabled us to investigate the efficacy of covert attention in the condition with complicated shapes. Our results indicate that both foveal and extrafoveal processing are simultaneously involved during a categorical search, and the specificity of their interaction is determined by the spatial orientation of objects, type of distractors, the prohibition to use overt attention, and individual characteristics of the participants.

Modelling that exploits visual elements and information visualisation are important areas that have contributed immensely to understanding and the computerisation advancements in many domains and yet remain unexplored for the benefit of the law and legal practice. This paper investigates the challenge of modelling and expressing structures and processes in legislation and the law by using visual modelling and information visualisation (InfoVis) to assist accessibility of legal knowledge, practice and knowledge formalisation as a basis for legal AI. The (...) paper uses a subset of the well-defined Unified Modelling Language (UML) to visually express the structure and process of the legislation and the law to create visual flow diagrams called lawmaps, which form the basis of further formalisation. A lawmap development methodology is presented and evaluated by creating a set of lawmaps for the practice of conveyancing and the Landlords and Tenants Act 1954 of the United Kingdom. This paper is the first of a new breed of preliminary solutions capable of application across all aspects, from legislation to practice; and capable of accelerating development of legal AI. (shrink)
