The image is the raw material of the twenty-first century. Images infiltrate all social and cultural spaces. Its digital-mediated realities drive communication, industry and knowledge. Images saturate life and adolescent learners are familiar with the participatory nature of image production and its social, educational and personal communicative realities. Vision and visibility, seeing and being now dominate how we inter-subjectively recognise ourselves and perform our world. We also find our aesthetic and embodied self increasingly constituted within imaging acts that are relational. (...) Visual culture may have colonised the self and learning, but imagination is without borders. The current pictorial turn opens possibilities to explore truth in flux through visual artistic acts. This article embeds Deleuzian method, which is one of intuitions, going beyond the actual, or our limited forms of representing life, to recognising that life has future imaginative potential forms and is always becoming. The article discusses an arts-based inquiry project for gifted artist visualiser/learners at an Australian regional university who are given broad topics on science phenomena and asked to give them expression. It suggests that pedagogies of the visual with their performative acts can prise open curriculum where an art-science interchange between two disciplines is made difficult by the current siloed nature of curriculum knowledge. Drawing on an analysis of Anika’s and Joel’s artworks and visual diaries it aims to reveal how their learning events dwell and are performed in aesthetic borderlands and how visual pedagogies forge new fluid visual borderlands and new learning.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Sharing God’s Company: A Theology of the Communion of Saints by David Matzko McCarthyMark RyanSharing God’s Company: A Theology of the Communion of Saints By David Matzko McCarthy GRAND RAPIDS: WILLIAM B. EERDMANS, 2012. 182 PP. $28.00What is the meaning of “communion” as it occurs in Christian references to the “Communion of Saints”? It clearly implies a particular social bond, but of what sort? David Matzko McCarthy observes (...) that recent attempts to account [End Page 192] for the saints and Christians’ relations with them tend to thin out the meaning of communion. Modern approaches turn saints into exemplars intended to inspire us as we live within egalitarian, leveled societies, whereas postmodern approaches turn the lives of the saints into texts, subject to interpretive play. In both approaches the possibility of real relationship is left behind as the saints become subservient to our modern sensibilities. What McCarthy seeks to revive is substantial, real relationships with saints that can draw us out of ourselves.In chapters 1 and 2 McCarthy uses the family to indicate the strong bonds signified by the Communion of Saints (COS)—bonds that respond to our “social desire.” The COS extends such kinship across time and space, without banishing ordinary time and particular places. Yet the kind of social tie embodied in the COS has been rendered a problem by our modern biases with regard to knowledge, representation, and social life—in short, our sense of reality. If we are to enrich our participation in the COS, McCarthy implies, we must work the metaphysical ground to make it a little more hospitable to the lives of the saints. The remaining chapters consider how the reality embodied in the COS challenges modern sensibilities with regard to what is real. They do so by allowing literary and visual representations of the saints—in hagiography, scripture, statues, and painting—to interrogate modern forms of representation and the assumptions about reality and time that underlie these forms.McCarthy uses Beverly Donofrio’s Looking for Mary to exemplify the trajectory of his book. Donofrio weaves together her own life and her pilgrimage to Medjugorge with the story of Mary from the Annunciation to the present day. Of particular importance, she narrates a transformation whereby her personal stories are engrafted into the life of Mary, rather than the other way around. In this, her story illustrates how Mary becomes the key agent in de-centering the author’s life as an autonomous agent, and resituating it in the COS with Mary as her patron and route. It shows the difference between an approach to the saints that domesticates them for use in our world and one where we surrender and become part of theirs.McCarthy’s previous work is notable for its concern with family and neighborhood as the practical context, or “home,” for the Christian life. In this book, “the question of home goes deeper. Does our life together here and now have any connection to the course of things and to life as a whole?” (8) In his introduction to the inaugural issue of the Journal of Moral Theology, which he edits, he mapped out the terrain of moral theology between “hyper-enchantment,” which seeks a magic bullet for modern ills, and impersonal mechanism, which posits a “nature” abstracted from human meanings. In this book, he begins to present a fuller vision of this terrain in the form of a kinship that stretches across time and place. As he writes, “The saints and their lives embody an [End Page 193] incarnational reality; they populate the borderlands between the future and now, there and here, and heaven and earth. … They bring ordinary life and people into a real experience of communitas” (53).The book is relevant to Christian ethics, then, because of its account of what we want most, and the moral ecology in which such desire could be at home. It is tempting to treat the COS as an optional “extra” to be added to the “factory model” of moral goodness in the Christian life. McCarthy’s exceptional gift is displayed in showing us how ordinary and basic is our desire to be part... (shrink)

This paper argues that a common form of representationalism has trouble accommodating empirical findings about visual space perception. Vision science tells us that the visual system systematically gives rise to different experiences of the same spatial property. This, combined with a naturalistic account of content, suggests that the same spatial property can have different veridical looks. I use this to argue that a common form of representationalism about spatial experience must be rejected. I conclude by considering alternatives to (...) this view. (shrink)

A set of visual search experiments tested the proposal that focused attention is needed to detect change. Displays were arrays of rectangles, with the target being the item that continually changed its orientation or contrast polarity. Five aspects of performance were examined: linearity of response, processing time, capacity, selectivity, and memory trace. Detection of change was found to be a self-terminating process requiring a time that increased linearly with the number of items in the display. Capacity for orientation was (...) found to be about 5 items, a value comparable to estimates of attentional capacity. Observers were able to filter out both static and dynamic variations in irrelevant properties. Analysis also indicated a memory for previously-attended locations. These results support the hypothesis that the process needed to detect change is much the same as the attentional process needed to detect complex static patterns. Interestingly, the features of orientation and polarity were found to be handled in somewhat different ways. Taken together, these results not only provide evidence that focused attention is needed to see change, but also show that change detection itself can provide new insights into the nature of attentional processing.

Some things look more complex than others. For example, a crenulate and richly organized leaf may seem more complex than a plain stone. What is the nature of this experience—and why do we have it in the first place? Here, we explore how object complexity serves as an efficiently extracted visual signal that the object merits further exploration. We algorithmically generated a library of geometric shapes and determined their complexity by computing the cumulative surprisal of their internal skeletons—essentially quantifying (...) the “amount of information” within each shape—and then used this approach to ask new questions about the perception of complexity. Experiments 1–3 asked what kind of mental process extracts visual complexity: a slow, deliberate, reflective process (as when we decide that an object is expensive or popular) or a fast, effortless, and automatic process (as when we see that an object is big or blue)? We placed simple and complex objects in visual search arrays and discovered that complex objects were easier to find among simple distractors than simple objects are among complex distractors—a classic search asymmetry indicating that complexity is prioritized in visual processing. Next, we explored the function of complexity: Why do we represent object complexity in the first place? Experiments 4–5 asked subjects to study serially presented objects in a self‐paced manner (for a later memory test); subjects dwelled longer on complex objects than simple objects—even when object shape was completely task‐irrelevant—suggesting a connection between visual complexity and exploratory engagement. Finally, Experiment 6 connected these implicit measures of complexity to explicit judgments. Collectively, these findings suggest that visual complexity is extracted efficiently and automatically, and even arouses a kind of “perceptual curiosity” about objects that encourages subsequent attentional engagement.

In this report, the phenomenology of two blind users of a sensory substitution device – “The vOICe” – that converts visual images to auditory signals is described. The users both report detailed visual phenomenology that developed within months of immersive use and has continued to evolve over a period of years. This visual phenomenology, although triggered through use of The vOICe, is likely to depend not only on online visualization of the auditory signal but also on the (...) users’ previous (albeit distant) experience of veridical vision (e.g. knowledge of shapes and visual perspective). Once established, the sensory substitution mapping between the auditory and visual domains is not confined to when the device is worn and, thus, may constitute an example of acquired synaesthesia.

In a recent response paper to Brogaard (2011a), Morten Overgaard and Thor Grünbaum argue that my case for the claim that blindsight subjects are not visually conscious of the stimuli they correctly identify rests on a mistaken necessary criterion for determining whether a conscious experience is visual or non-visual. Here I elaborate on the earlier argu- ment while conceding that the question of whether blindsight subjects are visually con- scious of the visual stimuli they correctly identify largely (...) is an empirical question. I conclude by sketching a method for testing whether blindsight subjects have visual con- sciousness of stimuli presented to them in their blind field. (shrink)

Background: Visual technologies are central to youth culture and are often the preferred communication means of adolescents. Although these tools can be beneficial in fostering relations, adolescents’ use of visual technologies and social media also raises ethical concerns. Aims: We explored how school public health nurses identify and resolve the ethical challenges involved in the use of visual technologies in health dialogues with adolescents. Research design: This is a qualitative study utilizing data from focus group discussions. Participants (...) and research context: We conducted focus group discussions using two semi-structured discussion guides with seven groups of public health nurses (n = 40) working in Norwegian school health services. The data were collected during January and October 2016. Discussions were audio recorded, transcribed, and coded into themes and subthemes using systematic text condensation. Ethical considerations: The leader of the public health nursing service who agreed to provide access for the study and the Norwegian Center for Research Data that reviewed and approved the study. All participants gave informed consent. Findings: In adolescents’ use of visual materials with public health nurses, ethical concerns were raised regarding suicide ideations, socially unacceptable content, violation of privacy, and presentations of possible child neglect. The nurses utilized their professional knowledge and experience when identifying and navigating these ethical dilemmas; they resolved ethical uncertainties through peer discussion and collaboration with fellow nurses and other professionals. Discussion: We discussed the findings in light of Annemarie Mol’s interpretation of the ethics of care. Mol expands the notion of ethical care to include the action of technologies. Conclusion: Although the increasing use of visual technologies offered benefits, school nurses faced ethical challenges in health dialogues with adolescents. To address and navigate these ethical issues, they relied on their experience and caring practices based on their professional ethics. Uncertainties were resolved through peer dialogue and guidance.

Research on visual attention has uncovered significant anomalies, and some traditional methods may have inadvertently probed peripheral vision rather than attention. Vision science needs to rethink visual attention from the ground up. To facilitate this, for a year I banned the word “attention” in my lab. This constraint promoted a more precise discussion of attention-related phenomena, capacity limits, and mechanisms. The insights gained lead me to challenge attributing to “attention” those phenomena that can be better explained by perceptual (...) processes, are predictable by an ideal observer model, or that otherwise may not require an additional mechanism. I enumerate a set of critical phenomena in need of explanation. Finally, I propose a unifying theory in which all perception results from performing a task, and tasks face a limit on complexity.

Anosognosia for visual deficits—cases where significant visual deficits go unnoticed—challenges the view that our own conscious experiences are what we know best. We review these widespread and striking failures of awareness. Anosognosia can occur with total blindness, visual abnormalities induced by brain lesions, and eye diseases. We show that anosognosia for visual deficits is surprisingly widespread. Building on previous accounts, we introduce a framework showing how apparently disparate forms of anosognosia fit together. The central idea is (...) that, to notice a deficit, individuals need to form expectations about normal vision, compare expectations and visual input, and judge any mismatch at the metacognitive level. A failure in any of these three steps may lead to unawareness of visual deficits. (shrink)

We experience our own body through both touch and vision. We further see that others’ bodies are similar to our own body, but we have no direct experience of touch on others’ bodies. Therefore, relations between vision and touch are important for the sense of self and for mental representation of one’s own body. For example, seeing the hand improves tactile acuity on the hand, compared to seeing a non-hand object. While several studies have demonstrated this visual enhancement of (...) touch effect, its relation to the ‘bodily self’, or mental representation of one’s own body remains unclear. We examined whether VET is an effect of seeing a hand, or of seeing my hand, using the rubber hand illusion. In this illusion, a prosthetic hand which is brushed synchronously—but not asynchronously—with one’s own hand is felt to actually be one’s hand. Thus, we manipulated whether or not participants felt like they were looking directly at their hand, while holding the actual stimulus they viewed constant. Tactile acuity was measured by having participants judge the orientation of square-wave gratings. Two characteristic effects of VET were observed: cross-modal enhancement from seeing the hand was inversely related to overall tactile acuity, and participants near sensory threshold showed significant improvement following synchronous stroking, compared to asynchronous stroking or no stroking at all. These results demonstrate a clear functional relation between the bodily self and basic tactile perception. (shrink)

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.

A theoretical approach relying on quantum computation in microtubules within neurons can potentially resolve the enigmatic features of visual consciousness, but raises other questions. For example, how can delicate quantum states, which in the technological realm demand extreme cold and isolation to avoid environmental ‘decoherence’, manage to survive in the warm, wet brain? And if such states could survive within neuronal cell interiors, how could quantum states grow to encompass the whole brain? We present a physiological model for (...) class='Hi'>visual consciousness that can accommodate brain-wide quantum computation according to the Penrose–Hameroff ‘Orch OR’ model. In this view, visual consciousness occurs as a series of several-hundred-millisecond epochs, each comprising ‘crescendo sequences’ of quantum computations occurring at ∼40 Hz. (shrink)

According to the Self-Location Thesis, certain types of visual experiences have self-locating and so first-person, spatial contents. Such self-locating contents are typically specified in relational egocentric terms. So understood, visual experiences provide support for the claim that there is a kind of self-consciousness found in experiential states. This paper critically examines the Self-Location Thesis with respect to dynamic-reflexive visual experiences, which involve the movement of an object toward the location of the perceiving subject. The main aim of (...) this paper is to offer an alternative interpretation of these cases which resists attributing them self-locating content, arguing for a replacement of the de se component with a non-conceptual equivalent of the indexical ‘here’. In its final section, the paper also considers an extension of the h-replacement account to cases of visual kinesthesis. (shrink)

Because visual narratives demand complex inference abilities, they can potentially be used as a tool for developing inferential skills in other domains, like reading. The Inferential Language Comprehension (iLC) Framework proposes an approach to using visual narratives in educational settings to sponsor inference skills by building on cognitive, developmental, and language research.

Based on the distinction between global and local levels of visual perception, here we studied different levels of reasoning in visual analogies. Specifically, we created problems that could be solved by inferring relations either between the global shapes (global path) or the underlying objects (object path). The problems varied in the saliency of the global shape, in the colour and familiarity of the objects, and in the presentation of the visual problem (simultaneous or sequential). The results of (...) three studies showed that the global path was used more frequently than the object path, particularly for images with salient global shapes such as objects placed in a circle. However, neither colour nor object familiarity affected the tendency to use the object path. Importantly, the tendency to use the global path correlated with analogical problem-solving in other visual and verbal tasks. Overall, these findings suggest that the global precedence observed in image perception also applies to visual analogical reasoning. Furthermore, the tendency to use the global path can be regarded as an informative measure of individual differences. (shrink)

Call the view that perceptual states can have propositional contents the ‘propositional view’ - or PV for short. Proponents of PV include John McDowell and Susanna Siegel; Anil Gupta and Charles Travis are prominent opponents. In this paper, I wish to address an argument against PV put forward by Anil Gupta. Gupta argues that the conjunction of PV with two further claims, which he calls the ‘Equivalence constraint’ and the ‘reliability constraint’, leads to skepticism. I shall argue that even if (...) we grant EC, Gupta has not given us a compelling reason for rejecting PV and that if we are faced with a choice between rejecting PV and RC, we should reject RC ahead of PV. I shall also suggest that Gupta’s account begs the question against one prominent version of PV. (shrink)

This paper aims to show that in ancient Greek architecture, it is possible to find a genesis of the geometric modeling of visual perception present in propositions of Euclid's Optics, considering mathematical knowledge as a human wisdom expression. Let us start by emphasizing that mathematical thinking is not exclusively rooted in mathematical disciplines, but also includes the broad spectrum of human activities, including activities that come from everyday life. Based on this, we present a socio-cultural characterization of human experience (...) as the source and sustainer of mathematical knowledge. Thereafter, on the basis of a content and contextual analysis of _Euclid's Optics_, we explain the use and development of geometry in the study of various optical effects of visual perception in the architectural art embodied in the Acropolis of Athens; and we focus our analysis on one of the most important of these effects, the Acropolis of Athens. We focus our analysis on one of the most emblematic architectural works of ancient Greek culture: the Parthenon of Athens. (shrink)

Oyeyemi's critique of racism in the United States focuses on the visual binary between whiteness and blackness, which she shows working in multiple ways to warp and distort relationships. In the Whitman family, children are valued (or not valued) according to how their skin color registers on a scale determined by white superiority. Oyeyemi's approach to racism takes the circuitous route of retelling the fairy tale of “Little Snow White,” thus calling into her own narrative a foundational text of (...) Western cultural aesthetics which links beauty to whiteness. (Snow White, whose skin is “white as snow,” is “fairest in the land.”) Rather than narrate a new version of the fairy tale, Oyeyemi separates out its elements – magic mirror, evil stepmother, and beautiful white stepdaughter – and develops each into a new thematic configuration. My analysis focuses on the subtle ways that Oyeyemi's reshaping of mirror, evil stepmother, and innocent beautiful young girl exposes the harms to children inflicted by allegiance to a (false) structure of visible difference between white skin and black skin.

This paper questions two prima facie plausible claims concerning switching in the presence of ambiguous figures. The first is the claim that reversing is an instantaneous process. The second is the claim that the ability to reverse demonstrates the interpretive, inferential and constructive nature of visual processing. Empirical studies show that optical and cerebral events related to switching protract in time in a way that clashes with its perceived instantaneity. The studies further suggest an alternative theory of reversing: according (...) to such alternative, seeing the same thing in multiple ways is a matter of uncovering what is already present to the senses through visual search.
