Drawing on video-recorded data from pre-climbing route mapping with visually impaired climbers and a sight guide, this study uses conversation analysis to investigate the situated deployment of the Italian presentative (e) hai ‘(and) you have’ within locally routinized multimodal Gestalts. The study shows that the guide uses (e) hai to progress route mapping and engage the athlete in tactile actions that target specific features of the route. In this context, (e) hai is packaged with noun phrases, silent pauses, bodily movements, (...) and touch. The arrangement of such syntactic and embodied components is shown to follow a recurrent trajectory in which, between (e) hai and its grammatical completion, syntactic suspension creates a dedicated slot for guide and athlete to physically attain the target object. Routine embeddedness of (e) hai within such arrangement is shown to provide specific affordances to the athletes to anticipate subsequent action and engage in its embodied implementation. (shrink)

The chapter presents the prototyping of a thinking routine designed to foster good inference habits in children ages 6 to 11. The prototyping was developed at Ninho, an educational project for children from underprivileged households in Brazil. The thinking routines by Ritchhart and colleagues (2006) served as our starting point. Following a Virtue Education (VE) approach, we supposed that the repeated application would conduce to habituation. In addition, to increase peer-to-peer interactions, the teacher applying the routines worked as (...) a facilitator in a Community of Inquiry (CI). After six months of application, the results were partially successful. We identified that the repeated exposition to the magic question “What makes you say that?” made children more aware of the evidence supporting their assumptions. Furthermore, the interactions between peers made them recognize different perspectives. However, we also identified some shortcomings. Most of them seemed to arise from cognitive biases. At the individual level, belief perseverance kept children too attached to their first assumptions. They preferred self-serving rationalizations instead of accepting a counter-argument. At the group level, we identified problems of social contagion such as information cascades. The effects of a first opinion rhetorically voiced were hard to efface. Since none of the steps on the previous routines addressed these biases, we prototyped a routine to start filling this gap. Following Critical Thinking (CT) theorists, we added a step of structured instruction concerning one specific reasoning technique - the inference to the best explanation. Moreover, the recommendation of cognitive psychologists motivated the inclusion of some extra features to avoid groupthink biases. For instance, a visual table that juxtaposes contrasting arguments should facilitate comparative evaluations. Also, a star-based evaluation scale should help different individuals to discuss their assessments based on a common ground. As described in the end, the prototype with elements from VE, CI and CT presented promising results. (shrink)

I identify three aspects to the puzzle of the speckled hen: A general puzzle, an epistemic puzzle, and a puzzle for the representationalist. These puzzles rely on an underlying “pictorialist” assumption, that we visually perceive general, determinable properties only in virtue of determinate properties or more specific, local features of our visual experience. This assumption is mistaken: Visual perception frequently starts from a position of uncertainty, and is routinely able to acquire information about general properties in the absence (...) of more specific information. Acknowledging that visual indeterminacy is structured this way resolves all three puzzles of the speckled hen. (shrink)

The on-going debate over the ‘admissible contents of perceptual experience’ concerns the range of properties that human beings are directly acquainted with in perceptual experience. Regarding vision, it is relatively uncontroversial that the following properties can figure in the contents of visual experience: colour, shape, illumination, spatial relations, motion, and texture. The controversy begins when we ask whether any properties besides these figure in visual experience. We argue that ‘ensemble properties’ should be added to the list of visually (...) admissible properties. Ensemble properties are features that belong to a set of perceptible objects as a whole as opposed to the individuals that constitute that set. They include such features as the mean size of an array of shapes or the average emotional expression of an array of faces. Recent work in vision science has yielded compelling evidence that the visual system routinely encodes such properties. We argue that epistemological considerations provide strong reasons to think that these properties figure in visual experience. Judgements about ensemble properties are immediately warranted by our perceptual experience, and the only plausible way that a perceptual experience could confer this warrant is if it confers awareness of ensemble properties.

The ArgumentIn 1787 an anonymous student of the Perth Academy spent countless hours transforming his rough classroom notes into a beautifully inscribed notebook. Though this was an everyday practice for many Enlightenment students, extant notebooks of this nature are extremely rare and we know very little about how middle class children learned to inscribe and visualize knowledge on paper. This essay addresses this lacuna by using recently located student notebooks, drawings, and marginalia alongside textbooks and instructional literature to identify the (...) graphic tools and skills that were taught to Scottish children in early modern classrooms. I show that, in addition to learning the facts of the curriculum, students participated in educational routines that enabled them to learn how to visually package knowledge into accessible figures and patterns of information, thereby making acts of inscription and visualization meaningful tools that benefitted both the self and society.

Recent debates over adults' theory of mind use have been fueled by surprising failures of perspective-taking in communication, suggesting that perspective-taking may be relatively effortful. Yet adults routinely engage in effortful processes when needed. How, then, should speakers and listeners allocate their resources to achieve successful communication? We begin with the observation that the shared goal of communication induces a natural division of labor: The resources one agent chooses to allocate toward perspective-taking should depend on their expectations about the other's (...) allocation. We formalize this idea in a resource-rational model augmenting recent probabilistic weighting accounts with a mechanism for (costly) control over the degree of perspective-taking. In a series of simulations, we first derive an intermediate degree of perspective weighting as an optimal trade-off between expected costs and benefits of perspective-taking. We then present two behavioral experiments testing novel predictions of our model. In Experiment 1, we manipulated the presence or absence of occlusions in a director–matcher task. We found that speakers spontaneously modulated the informativeness of their descriptions to account for “known unknowns” in their partner's private view, reflecting a higher degree of speaker perspective-taking than previously acknowledged. In Experiment 2, we then compared the scripted utterances used by confederates in prior work with those produced in interactions with unscripted directors. We found that confederates were systematically less informative than listeners would initially expect given the presence of occlusions, but listeners used violations to adaptively make fewer errors over time. Taken together, our work suggests that people are not simply “mindblind”; they use contextually appropriate expectations to navigate the division of labor with their partner. We discuss how a resource-rational framework may provide a more deeply explanatory foundation for understanding flexible perspective-taking under processing constraints. (shrink)

A large proportion of hospital inpatients are affected by cognitive impairment, posing challenges in the provision of their care in busy, fast-paced acute wards. Signs and symbols, known as visual identifiers, are employed in many U.K. hospitals with the intention of helping healthcare professionals identify and respond to the needs of these patients. Although widely considered useful, these tools are used inconsistently, have not been subject to full evaluation, and attract criticism for acting as a shorthand for a routinized (...) response. In order for visual identifiers to be used effectively in acute care settings, thorough consideration must be given to the ethical and legal issues that are engaged in this context, and their potential benefits and harms must be weighed and balanced. This paper proposes a set of legal and ethical principles that can be used to guide the implementation of visual identifiers. Together, these principles provide a framework applicable in the design and implementation phases to systematically identify relevant considerations arising from the use of these tools. We outline some tensions that arise between principles and conclude that selecting a preferred moral framework could help to guide decision-making, as does clarity around the purpose and objectives of the identifier.

When the International Atomic Energy Agency (IAEA) began operations in 1958, one of its first routine tasks was to create and circulate a brief non-technical periodical. This article analyses the creation of theIAEA Bulletinand its circulation during its first years. It finds that diplomatic imperatives both in IAEA leadership circles and in the networks outside them shaped the form and appearance of the bulletin. In the hands of the IAEA's Division of Public Information, the bulletin became an instrument of science (...) diplomacy, its imagery conveying the motivations for member states to strengthen ties with the IAEA, while simultaneously persuading them to accept the hierarchies and geopolitical logics implicit in those relations, as well as to endorse the central position of the IAEA as a clearing house and authority of globally circulating nuclear objects and information.

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.

Behavioral scientists routinely publish broad claims about human psychology and behavior in the world's top journals based on samples drawn entirely from Western, Educated, Industrialized, Rich, and Democratic (WEIRD) societies. Researchers – often implicitly – assume that either there is little variation across human populations, or that these “standard subjects” are as representative of the species as any other population. Are these assumptions justified? Here, our review of the comparative database from across the behavioral sciences suggests both that there is (...) substantial variability in experimental results across populations and that WEIRD subjects are particularly unusual compared with the rest of the species – frequent outliers. The domains reviewed include visual perception, fairness, cooperation, spatial reasoning, categorization and inferential induction, moral reasoning, reasoning styles, self-concepts and related motivations, and the heritability of IQ. The findings suggest that members of WEIRD societies, including young children, are among the least representative populations one could find for generalizing about humans. Many of these findings involve domains that are associated with fundamental aspects of psychology, motivation, and behavior – hence, there are no obviousa priorigrounds for claiming that a particular behavioral phenomenon is universal based on sampling from a single subpopulation. Overall, these empirical patterns suggests that we need to be less cavalier in addressing questions ofhumannature on the basis of data drawn from this particularly thin, and rather unusual, slice of humanity. We close by proposing ways to structurally re-organize the behavioral sciences to best tackle these challenges. (shrink)

Artworks are attentional engines, or artifacts intentionally designed to direct attention to formal features that are diagnostic for their artistically salient aesthetic, expressive, and semantic content. This is nowhere more true than the movies. Moving pictures are constructed from a suite of formal and narrative devices carefully developed to capture, hold, and direct our attention. These devices are tools for developing content by controlling the way information is presented throughout the duration of our engagement with a movie. In this respect (...) moving pictures are analogous to visual routines used to direct and bias attention in natural behavior - they are artifacts used to deliver information on the fly as it is needed for the development of the narrative. This article reviews some of the fundamental devices movie makers use to discharge this function - such as variable framing and criterial prefocusing – and discusses their relation to our underlying cognitive, affective, and neurological architecture. These formal devices are designed to guide and control salient aspects of viewers behavioral responses to mass market movies. Therefore, we argue that it is no surprise to discover that that they are fine tuned to the architecture of emotion, perception, and cognition. (shrink)

This article describes an implemented architecture for intermediate vision. By integrating a variety of Intermediate visual mechanisms and putting them to use in support of concrete activity, the implementation demonstrates their utility. The sytem, SIVS, models psychophysical discoveries about visual attention and search. It is designed to be efficiently implementable in slow, massively parallel, locally connected hardware, such as that of the brain.SIVS addresses five fundamental problems. Visual attention is required to restrict processing to task-relevant locations in (...) the image. Visual search finds such locations. Visual routines are a means for nonuniform processing based on task demands. Intermediate objects keep track of intermediate results of this processing. Visual operators are a set of relatively abstract, general-purpose primitives for spatial analysis, out of which visual routines are assembled. (shrink)

Cultural routines, such as reading and writing direction (script direction), channel attention orientation. Depending on one's native language habit, attention is biased from left‐to‐right (LR) or from right‐to‐left (RL). Here, we further document this bias, as it interacts with the spatial directionality that grounds time concepts. We used a spatial cueing task to test whether script direction and the grounding of time in Portuguese (LR, Exp. 1) and Arabic (RL, Exp. 2) shape visuomotor performance in target discrimination. Temporal words (...) (e.g., tomorrow, yesterday) were presented as cues in two modalities: visual (Exp. 1–2) and auditory (Exp. 1). Gaze movement (Exp. 1) and speed of discrimination decisions (Exp. 1–2) of targets presented to the left or right sides of the screen were assessed. As predicted, the interaction between target location and time concepts was significant across both modalities and linguistic communities. Additionally, LR participants detected the target on the right side of the screen faster after a future word than the target on the left side of the screen after a past word cue. In contrast, RL participants detected the target on the left side of the screen faster when the cue word was a future word than the target on the right side of the screen cued by a past word. In both modalities, the initial eye‐gaze movement (Exp. 1) was responsive to the cue's time referent, further confirming that time orients attention. An additional bias was observed for the first fixation onset, which landed earlier on the target set that matched habitualized spatial routines. We conclude that scanning regularities are shaped by writing habits and bodily grounded categorical features. (shrink)

Ballard and Zhang offer a fascinating review of how computational models of human vision have evolved since David Marr proposed his Tri‐Level Hypothesis, with a focus on the refinement of algorithm descriptions over time.

ABSTRACT:Are face-to-face perception and picture perception different perceptual phenomena? The question is controversial. On the one hand, philosophers have offered several solid arguments showing that, despite some resemblances, they are quite different perceptual phenomena and that pictures are special objects of perception. On the other hand, neuroscientists routinely use pictures in experimental settings as substitutes for normal objects, and this practice is successful in explaining how the human visual system works. But this seems to imply that face-to-face perception and (...) picture perception are very similar, if not actually the same. How can we decide between these two opposite intuitions? Here I offer a regimentation of the notion of picture perception that can reconcile these two apparently conflicting ideas about pictures. It follows that philosophers and neuroscientists can maintain their respective stances without any theoretical conflict. (shrink)

Humans routinely modify their walking speed to adapt to functional goals and physical demands. However, damage to the central nervous system often results in abnormal modulation of walking speed and increased risk of falls. There is considerable interest in treatment modalities that can provide safe and salient training opportunities, feedback about walking performance, and that may augment less reliable sensory feedback within the CNS after injury or disease. Fully immersive virtual reality technologies show benefits in boosting training-related gains in walking (...) performance; however, they lack views of the real world that may limit functional carryover. Augmented reality and mixed reality head-mount displays provide partially immersive environments to extend the virtual reality benefits of interacting with virtual objects but within an unobstructed view of the real world. Despite this potential advantage, the feasibility of using MR-HMD visual feedback to promote goal-directed changes in overground walking speed remains unclear. Thus, we developed and evaluated a novel mixed reality application using the Microsoft HoloLens MR-HMD that provided real-time walking speed targets and augmented visual feedback during overground walking. We tested the application in a group of adults not living with disability and examined if they could use the targets and visual feedback to walk at 85%, 100%, and 115% of each individual’s self-selected speed. We examined whether individuals were able to meet each target gait speed and explored differences in accuracy across repeated trials and at the different speeds. Additionally, given the importance of task-specificity to therapeutic interventions, we examined if walking speed adjustment strategies were consistent with those observed during usual overground walking, and if walking with the MR-HMD resulted in increased variability in gait parameters. Overall, participants matched their overground walking speed to the target speed of the MR-HMD visual feedback conditions. The percent inaccuracy was approximately 5% across all speed matching conditions and remained consistent across walking trials after the first overall walking trial. Walking with the MR-HMD did not result in more variability in walking speed, however, we observed more variability in stride length and time when walking with feedback from the MR-HMD compared to walking without feedback. The findings offer support for mixed reality-based visual feedback as a method to provoke goal-specific changes in overground walking behavior. Further studies are necessary to determine the clinical safety and efficacy of this MR-HMD technology to provide extrinsic sensory feedback in combination with traditional treatments in rehabilitation.

Studies of change detection suggest that people tend to overestimate their ability to detect visual changes. In a recent laboratory study of change detection and human intention, Beck et al., found that individuals have an inadequate understanding that intention can improve change detection performance and that its importance increases with scene complexity. We note that these findings may be specific to unfamiliar situations such as those generated routinely in studies of change detection. In two questionnaire studies, we demonstrate that (...) when participants consider real world scenarios such as driving, people are well aware that the intention to detect changes improves detection performance, especially in complex scenes. We suggest several reasons why change detection findings like Beck et al.’s do not generalize to real world situations. More broadly, we suggest a possible way to bridge the gap between lab and life.

Cognitive scientists routinely distinguish between controlled and automatic mental processes. Through learning, practice, and exposure, controlled processes can become automatic; however, whether automatic processes can become deautomatized – recuperated under the purview of control – remains unclear. Here we show that a suggestion derails a deeply ingrained process involving involuntary audiovisual integration. We compared the performance of highly versus less hypnotically suggestible individuals in a classic McGurk paradigm – a perceptual illusion task demonstrating the influence of visual facial movements (...) on auditory speech percepts. Following a posthypnotic suggestion to prioritize auditory input, HSIs but not LSIs manifested fewer illusory auditory perceptions and correctly identified more auditory percepts. Our findings demonstrate that a suggestion deautomatized a ballistic audiovisual process in HSIs. In addition to guiding our knowledge regarding theories and mechanisms of automaticity, the present findings pave the road to a more scientific understanding of top-down effects and multisensory integration.

Mental representations remain the central posits of psychology after many decades of scrutiny. However, there is no consensus about the representational format(s) of biological cognition. This paper provides a survey of evidence from computational cognitive psychology, perceptual psychology, developmental psychology, comparative psychology, and social psychology, and concludes that one type of format that routinely crops up is the language-of-thought (LoT). We outline six core properties of LoTs: (i) discrete constituents; (ii) role-filler independence; (iii) predicate–argument structure; (iv) logical operators; (v) inferential (...) promiscuity; and (vi) abstract content. These properties cluster together throughout cognitive science. Bayesian computational modeling, compositional features of object perception, complex infant and animal reasoning, and automatic, intuitive cognition in adults all implicate LoT-like structures. Instead of regarding LoT as a relic of the previous century, researchers in cognitive science and philosophy-of-mind must take seriously the explanatory breadth of LoT-based architectures. We grant that the mind may harbor many formats and architectures, including iconic and associative structures as well as deep-neural-network-like architectures. However, as computational/representational approaches to the mind continue to advance, classical compositional symbolic structures – that is, LoTs – only prove more flexible and well-supported over time.

The authors show that some long-standing confusions and problems can be avoided by thinking of perception in terms of sensorimotor contingencies, a close kin to my heterophenomenological approach (Dennett 1991). However, their claim that subjects do not have any commitments about the resolution of their visual fields is belied by the surprise routinely expressed by subjects when this is demonstrated to them.

In _Action in Perception _Alva No develops and presents a sensorimotor account of vision and of visual consciousness. According to such an account seeing (and indeed perceiving more generally) is analysed as a kind of skilful bodily activity. Such a view is consistent with the emerging emphasis, in both philosophy and cognitive science, on the critical role of embodiment in the construction of intelligent agency. I shall argue, however, that the full sensorimotor model faces three important challenges. The first (...) is to negotiate a path between two prima facie unsatisfactory readings of the central claim that conscious perceptual experience is constituted by knowledge of patterns of sensorimotor dependence. The second is to convince us that the sensorimotor contribution, in such cases, is actually constitutive of perceptual experience rather than merely causally implicated in the origination of such experience.² And the third is to respond to the important challenge raised by what I will dub 'sensorimotor summarizing' models of the relation between conscious experience and richly detailed sensorimotor routines. According to such models³ conscious perceptual experience only rather indirectly reflects the rich detail of our actual sensorimotor engagements, which are instead lightly sampled as a coarse guide, optimized for planning and reasoning, and geared and filtered according to current needs and purposes.

H. B. D. Kettlewell's (1955, 1956) classic field experiments on industrial melanism in polluted and unpolluted settings using the peppered moth, Biston betularia, are routinely cited as establishing that the melanic (dark) form of the moth rose in frequency downwind of industrial centers because of the cryptic advantage dark coloration provides against visual predators in soot-darkened environments. This paper critiques three common myths surrounding these investigations: (1) that Kettlewell used a model that identified crypsis as the only selective force (...) responsible for the spread of the melanic gene, (2) that Kettlewell's field experiments alone established that selection for crypsis was the most important factor in the spread of melanic forms, and (3) that Kettlewell's investigations in an unpolluted wood near Dorset constituted a control for his earlier Birmingham studies (contra Hagen 1993, 1996). This analysis further identifies two features that distinguish manipulative experiments in evolutionary biology from experiments in other contexts. First, experiments in evolutionary biology rest on a wealth of information provided by strictly observational ecological studies; in the absence of such information experiments in evolutionary biology make no sense. Second, there is a trade-off between how much control investigators have over the conditions being studied and how informative the results of the experiment will be with regard to natural populations.

Using in-depth interviews with forty transgender people, I explore “discursive aggression,” a term for the communicative acts used in social interaction to hold people accountable to social- and cultural-based expectations, and subsequently to reinforce inequality in everyday life. I show how these interactional affronts restore social order, are based in dominant language systems, and reflect expectations for how interactions should unfold. Gendered expectations—such as the assumption that gender is identifiable based on visual cues alone—come to life through language, are (...) delivered through discursive aggression, and become routinized micro-inequalities that people negotiate in interaction. I present five vignettes to exemplify how discursive aggression typically unfolds in interaction. In so doing, this research demonstrates the value of discursive aggression as a concept to capture a pervasive, yet under-examined, feature of everyday life and a mechanism for how power is reified in interaction.

The main aim of this paper is to clarify the relation between epistemic feel- ings, mental action, and self-ascription. Acting mentally and/or thinking about one’s mental states are two possible outcomes of epistemic or metacognitive feelings. Our men- tal actions are often guided by our E-feelings, such as when we check what we just saw based on a feeling of visual uncertainty; but thought about our own perceptual states and capacities can also be triggered by the same E-feelings. The (...) first section of the pa- per presents Dokic’s argument for the insufficiency of the “ascent routine” to account for non-transparent cases of self-ascription, as well as his account of E-feelings. The second section then presents a two-level model of metacognition that builds on Dokic’s account and my own view of the issue. The two-level model links E-feelings to a min- dreading capacity in order to account for non-transparent self-ascriptions. Finally, the third section develops a deeper characterization of the relation among E-feelings, mental action, and self-ascription of mental states based on epistemic rules. In the context of self-knowledge, these remarks suggest the existence of means of forming self-ascriptions other than the ascent routine. (shrink)

The article explores digital literacy practices in children’s everyday lives at Norwegian preschools and some of the ways in which young children appropriate basic digital literacy skills through guided participation in situated activities. Building on an ethnomethodological perspective, the analyses are based on 70 hours of video recordings documenting the activities in which 45 children, aged 5-6, and eight preschool teachers participated. Through the detailed analysis of two categorization activities – identifying geometrical shapes and identifying feelings/thoughts –the use of digital (...) tools in the social organization of the activities are examined. The article finds that children’s digital literacy activities encompass visual, verbal, audio and embodied competencies that are made relevant, and thus accessible for learning, in interaction between the children and between the adults and children in the form of norms and guidelines for what constitutes correct categorizations (geometrical shapes and green and red feelings) in the situated activities, and that are appropriated and actualized by the children in interaction with their peers. The findings also show how the categorization practices in preschools deal with symbols and labels in ways that create and sustain socially organized ways of knowing, seeing and acting upon the world. Digital media are embedded in routines, procedures and socialites that are part of these categorization practices; they are part of how children are instructed to experience, interpret, understand and act in the world. Moreover, the different technologies created different conditions for the children’s participation. It was found that peer interaction was part of the digital literacy activities that involved such mobile technologies as smartphones and tablets, while when using non-mobile technologies, e.g. smartboards, the activities were structured more as ‘classic’ classroom activities, primarily guided by the teacher and the didactic material presented through the smartboard.

Selective reproductive technologies, such as preimplantation genetic diagnosis, enable enhanced clinical success rates, create reproductive choices, and produce new commercial opportunities. Drawing upon empirical material acquired during a ten-month period in 2016, this study uses a total of twenty-two in-depth interviews with doctors, CEOs, clinical directors, marketing directors, patient counselors, and embryologists to discuss how traveling for the SRT of gender selection for nonmedical reasons is mediated by fertility clinics and clinicians in Dubai. Multimodal analysis was used to analyze the (...) clinical websites’ key rhetorical and visual features. Meanwhile, interviews and observational studies highlighted the context within which gender selection takes place. Findings revealed that gender selection is promoted as a form of “enhancement” and “family balance,” which, when combined with the ways that Dubai is assembled as a sensory tourist destination, routinize SRTs and lead to an understanding of gender selection as not merely an individualized reproductive journey but an optimization of the family unit.

This article explores the organization of instructional corrections in pre-clinical dental education. The students are practising manual skills using a simulator and tutors are inspecting and evaluating their progress. Simulators and simulation are critical to the organization of contemporary healthcare training, and the academic literature that explores forms of simulation in healthcare tends to consider the ‘fidelity’ of systems and the extent to which they match the clinical situations that they are designed to mimic. In contrast, this article considers how (...) tutors and students explicitly attend to matters of realism in the course of instructional sequences. We highlight the ways in which tutors routinely invoke ‘real life’ in instructional corrections and we discuss how these sequences reveal the work that tutors undertake to compensate for the ‘chronic insufficiency’ of the simulator. We show how tutors emphasize the reasoned character of manual bodily skills, reasons linked to the complexities and contingencies of clinical practice. To explore these issues and concerns, the article draws on the analysis of audio-visual data of everyday instruction. (shrink)

Our seamless perception of the world depends very much on the slow time scales used by conscious perception. Time scales longer than one second are needed to assemble conscious experience. At time scales shorter than one second, this seamlessness quickly deteriorates. Numerous experiments reveal the fragmentary nature of the visual information used to construct visual experience. Models of how the brain manages these fragments use the construct of a routine, which is a task-specific fragment of a sensory-motor program. (...) This paper provides an overview of some of the experiments that test these models. Its aim is to show how the structures that they elucidate constrain the understanding of conscious perception.

This paper examines the vital role played by electron microscopy toward the modern definition of viruses, as formulated in the late 1950s. Before the 1930s viruses could neither be visualized by available technologies nor grown in artificial media. As such they were usually identified by their ability to cause diseases in their hosts and defined in such negative terms as “ultramicroscopic” or invisible infectious agents that could not be cultivated outside living cells. The invention of the electron microscope, with magnification (...) and resolution powers several orders of magnitude better than that of optical instruments, opened up possibilities for biological applications. The hitherto invisible viruses lent themselves especially well to investigation with this new instrument. We first offer a historical consideration of the development of the instrument and, more significantly, advances in techniques for preparing and observing specimens that turned the electron microscope into a routine biological tool. We then describe the ways in which the electron microscopic images, or micrographs, functioned as forms of new knowledge about viruses and resulted in a paradigm shift in the very definition of these entities. Micrographs were not mere illustrations since they did the work for the electron microscopists. Drawing extensively on primary publications, we adduce the role of the new instrument in understanding the so-called eclipse phase in virus multiplication and the unexpected spinoffs of data from electron microscopy in naming and classifying viruses. Thus, we show that electron microscopy functioned not only to provide evidence, but also arguments in facilitating a reordering of the world that it brought into the visual realm. (shrink)

This article aims to analyze the tiger-hunting scene on Yeh Pulu relief, located in Bedulu Village, Gianyar, Bali. This relief is estimated to have been created by Balinese artists of the end of the era of Ancient Bali Kingdom in about the 14th century AD. There are only few in-depth studies conducted on this monumental relief in the context of iconology by visual art researchers. Therefore, the author has conducted intensive field research and studies since a year ago based (...) on Panofsky's iconology theory. Tiger-hunting is part of a series of scenes on the relief which in general tends to tell about everyday routines. The tiger-hunting scene carries an unusual theme amidst a wide range of Balinese cultural artifacts which tend to revolve around mythology and epics such as Mahabrata and Ramayana. Based on the theory of iconology which consists of a sequence of analyses starting from the pre-iconographic analysis, the relief characters were found in the form of rough sculptures on the surface of a rocky soil wall located near the Petanu watershed in Gianyar. The iconography aspects revealed that the characters on the relief figuration tend to be naturalistic; and iconologically, they tend to relate to the meaning of narratives on the romanticism of everyday heroism. Heroism nurtures the Balinese people's proletariat side in facing challenges in their life and the political power in the era of the Ancient Bali Kingdom. (shrink)

This study investigated the effect of stroking vs. simple human presence on later reactions of dairy cows to routine veterinary handling. While in two groups of cows the experimenter stroked the ventral part of the neck or the withers for three consecutive weeks, the third group was exposed to close visual presence. After the treatment period the cows were subjected to rectal palpation. The three groups differed significantly in stepping during rectal palpation, which occurred less often in Neck- and (...) Withers-animals than in control animals. Heart rate increase was significantly higher in the control group than in the two stroking groups. Previous stroking led to fewer stress reactions during the rectal palpation, possibly due to a combined effect of improved relationship towards and thus perception of humans and lasting anti-stress effects of tactile stimulation.

Based on electrophysiological and anatomical studies, a prevalent conception is that the visual system recovers features of the world from retinal images to generate perceptions and guide behavior. This paradigm, however, is unable to explain why visual perceptions differ from physical measurements, or how behavior could routinely succeed on this basis. An alternative is that vision does not recover features of the world, but assigns perceptual qualities empirically by associating frequently occurring stimulus patterns with useful responses on the (...) basis of survival and reproductive success. The purpose of the present article is to briefly describe this strategy of vision and the evidence for it. (shrink)

A major cognitive framework for individuating, visualizing, and keeping track of different items of knowledge (such as who said what in a conference or what items of data go with what) is the use of real 3D spatial locations. We use space both literally (as in the desktop or office model of data organization) and also figuratively. Examples of the latter includes such techniques as mentally locating different facts and premises in certain imagined spatial loci -- a technique widely used (...) in mnemonic aids, and the use of spatial location in reasoning where so-called "spatial paralogic" provides an important scheme for keeping track of different components of a problem. The use of distinct spatial loci in reasoning and visualizing can be enhanced and its effectiveness in communication increased if distinct spatial locations can be shared. This, of course, happens routinely when people use gestures, pointing, and carving shapes in the air when they converse. Sharing a common workspace and conceptual space is now becoming technologically feasible through the use of interactive multimedia workstations, in which sound and 3D visual locations can be communicated and spatial indicators such as pointing in space can form part of the human-computer interaction.

This paper examines the vital role played by electron microscopy toward the modern definition of viruses, as formulated in the late 1950s. Before the 1930s viruses could neither be visualized by available technologies nor grown in artificial media. As such they were usually identified by their ability to cause diseases in their hosts and defined in such negative terms as “ultramicroscopic” or invisible infectious agents that could not be cultivated outside living cells. The invention of the electron microscope, with magnification (...) and resolution powers several orders of magnitude better than that of optical instruments, opened up possibilities for biological applications. The hitherto invisible viruses lent themselves especially well to investigation with this new instrument. We first offer a historical consideration of the development of the instrument and, more significantly, advances in techniques for preparing and observing specimens that turned the electron microscope into a routine biological tool. We then describe the ways in which the electron microscopic images, or micrographs, functioned as forms of new knowledge about viruses and resulted in a paradigm shift in the very definition of these entities. Micrographs were not mere illustrations since they did the work for the electron microscopists. Drawing extensively on primary publications, we adduce the role of the new instrument in understanding the so-called eclipse phase in virus multiplication and the unexpected spinoffs of data from electron microscopy in naming and classifying viruses. Thus, we show that electron microscopy functioned not only to provide evidence, but also arguments in facilitating a reordering of the world that it brought into the visual realm. (shrink)

Recent advances in neuroimaging technologies have rendered multimodal analysis of operators’ cognitive processes in complex task settings and environments increasingly more practical. In this exploratory study, we utilized optical brain imaging and mobile eye tracking technologies to investigate the behavioral and neurophysiological differences among expert and novice operators while they operated a human-machine interface in normal and adverse conditions. In congruence with related work, we observed that experts tended to have lower prefrontal oxygenation and exhibit gaze patterns that are better (...) aligned with the optimal task sequence with shorter fixation durations as compared to novices. These trends reached statistical significance only in the adverse condition where the operators were prompted with an unexpected error message. Comparisons between hemodynamic and gaze measures before and after the error message indicated that experts’ neurophysiological response to the error involved a systematic increase in bilateral dorsolateral prefrontal cortex (dlPFC) activity accompanied with an increase in fixation durations, which suggests a shift in their attentional state, possibly from routine process execution to problem detection and resolution. The novices’ response was not as strong as that of experts, including a slight increase only in the left dlPFC with a decreasing trend in fixation durations, which is indicative of visual search behavior for possible cues to make sense of the unanticipated situation. A linear discriminant analysis model capitalizing on the covariance structure among hemodynamic and eye movement measures could distinguish experts from novices with 91% accuracy. Despite the small sample size, the performance of the linear discriminant analysis combining eye fixation and dorsolateral oxygenation measures before and after an unexpected event suggests that multimodal approaches may be fruitful for distinguishing novice and expert performance in similar neuroergonomic applications in the field.

The perception and cognition of art, a venture done effortlessly by all members of our species, is a complicated affair in which visual perception, brain structures, sensory reasoning, and aesthetic evaluation are made in less time that it takes to read this sentence. Only recently, through perceptual/brain studies, have we begun to understand the many neurological sub-routines involved in visual perception. The discoveries made in cognitive neuroscience laboratories have helped us better understand the perception of everyday (...) class='Hi'>visual phenomena, including the perception of art. In addition, cognitive neuroscientists have provided techniques and instruments which are valuable in the study of the psychology of art. In this paper I give an overview of the past research which has advanced our understanding of how people process visual art. In addition the results of a preliminary study of an accomplished artist as he drew a portrait while in an MRI machine are presented. (shrink)

Maps provide us with an easily recognizable version of the new demarcation problem: On the one hand, we are all familiar with graphics and maps that unacceptably distort our perceptions without being technically inaccurate or fictive; indeed there are whole websites groups devoted to curating such images for fun. On the other hand, there are multiple unavoidably value-laden choices that must be made in the production of any map. Producing a map requires choosing everything from the colors and thicknesses of (...) the lines, the scale, the projection system, the categories and parameters represented, and much more. There is no neutral default for any of these choices, and all of them shape what information the map communicates. All the visual choices involved in producing a map enable some information to be conveyed at the cost of hiding or distorting other information, as map makers themselves routinely acknowledge and discuss. Hence there are no straightforward answers to questions about the line between distortion and legitimate representational choices. I explore three distinctive kinds of epistemic risks in map-making that generate special versions of the demarcation problem, which I dub aesthetic risk, categorization risk, and simplification risk. I argue that in each case, even good maps – maps that are accurate and epistemically valuable – have the potential to mislead us. I end by looking at maps that offer special epistemic benefits by making clear their own lack of value-neutrality while still being accurate and epistemically fecund. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Fashioning the "Order of Saint Clare." A Rule illuminated by Neri da Rimini:Princeton University Library MS 83 in contextFrances Andrews (bio) and Louise Bourdua (bio)KeywordsRule of Urban IV, Clare of Assisi, Urbanist Clare nuns, Manuscript illumination, Neri da RiminiIntroduction1This interdisciplinary essay is an investigation of an illuminated, early 14th-century copy of the rule of the "Order of Saint Clare" issued by Pope Urban IV in 1263, now in Princeton. (...) It examines the unprecedented visual language adopted in a female Franciscan context to authorize their way of life, and places the manuscript in context, exploring how it relates to other early representations showing Saints Francis and Clare together and documenting the production of this and comparable early rule manuscripts, including a previously unpublished copy now in Venice.2Thousands of manuscript copies of rules of life were produced in and for late medieval religious houses and their members, good numbers of which remain extant, though these are scarce remnants of what must originally have been produced. Rules do sometimes appear in extant library inventories,3 but unlike individual books destined for personal [End Page 75] prayer or study and ultimately deposit in a conventual library, their primary purpose was as legal texts binding all who professed them.4 In their iterative function, read and reread, alone or aloud in the community, they were comparable to liturgical books, though they were not for use in church nor kept in the sacristy.5 In the rule of Urban IV for the Order of Saint Clare investigated here, chapter twenty-four required that the rule be read and explained annually by the visitator, while the final chapter emphasized that it be read once each fortnight lest the sisters neglect it.6 This sort of repetition must have ensured most nuns knew the rule by memory, having first encountered its details as novices, with no need to own the text. Copies were perhaps in the hands of the abbess, a visitator, or other monastic superior, or kept in the chapter room or refectory, ready for routine use.7 Nonetheless, wealthier women may have had a copy prepared or received one as a gift, either on entering the religious life or on becoming a superior responsible for its observance.8Princeton University Library, Manuscripts Division, Department of Rare Books and Special Collections, MS 83, contains a Latin, [End Page 76] professionally made and illuminated copy of the text designed to substitute existing rules, including the 1219 Forma Vitae issued by Cardinal Hugolino and the rule of Innocent IV from 1247.9 Clare's own hard-fought for rule, approved in 1253, was initially for the San Damiano community alone and was followed in subsequent decades by a very small group of houses.10 The making of Urban IV's rule, adopted instead by hundreds of communities, has been much discussed, but the survival of this early illuminated copy has gone unnoticed outside the library catalog.11 The manuscript includes the earliest extant sequence known to us showing Clare of Assisi receiving the rule from the pope and in turn taking the profession of her sisters, images designed to legitimize the new order by building ties to its "founder" while yet acknowledging its papal origins. Among extant imagery it is pioneering. The large, illuminated initials have been recognized as painted by Nerius da Rimini and his workshop but the case has never been set out and PUL MS 83 has [End Page 77] not been included in accounts of this artist's production.12 Better known as "Neri," he is a comparatively well-documented manuscript illuminator whose signatures sometimes survive on his work, a rare practice at this date.13Historians of medieval women religious are by now familiar with books produced by women themselves.14 A beautiful manuscript, for example, containing Bonaventure's Legenda Maior of Saint Francis, the Vita beati Antonii and documents relating to the Portiuncula indulgence was written in Latin in 1337 by two sisters, Elspet von Amberk and Katerina von Purchausen, perhaps living in the Paradies convent in Diessenhofen (Switzerland).15 Other women have been identified as skilled illuminators.16 The prolific activity of...

This study investigated the effect of stroking vs. simple human presence on later reactions of dairy cows to routine veterinary handling. While in two groups of cows the experimenter stroked the ventral part of the neck or the withers for three consecutive weeks, the third group was exposed to close visual presence. After the treatment period the cows were subjected to rectal palpation. The three groups differed significantly in stepping during rectal palpation, which occurred less often in Neck- and (...) Withers-animals than in control animals. Heart rate increase was significantly higher in the control group than in the two stroking groups. Previous stroking led to fewer stress reactions during the rectal palpation, possibly due to a combined effect of improved relationship towards and thus perception of humans and lasting anti-stress effects of tactile stimulation. Keywords: cattle; tactile stimulation; human–animal relationship; animal welfare. (shrink)

British art historian Charles Harrison presumes the existence of a patriarchal world with power in the hands of men who dominate the representation of women and femininity. He applauds the ground-breaking work of feminist theorists who have questioned this imbalance of power since the 1970s. He stops short, however, of accepting their claims that all women have been represented by male artists as images of “utter passivity” (p. 4), routinely reduced by the male gaze to the status of exploited sexual (...) objects, or that women’s subjectivity is eroded by the visual treatment they receive at the hands of male artists such as Manet and Picasso. He wants to show that what is depicted in the picture plane by the (typically male) artist and enjoyed by the (typically male) spectator is more nuanced than just a simple privileged understanding between two men. He adds a third (and possibly fourth or more) party to the mix when he significantly redefines and expands our concept of the gaze: “A gaze may also be conceived of as a function of a painting’s represented content” (p. 9). In other words, a gaze may be “addressed outward by a represented figure,” and regardless of who and where, “the assumption conveyed by the term [‘gaze’] is that some differential and usually asymmetrical relation will be at stake in any exchange between one who directs the gaze and another at whom it is directed. In fact, it is just this difference—in age, in sex, in class, in interest, in power —that the operation of the gaze tends to mark” (p. 9). Referring to a woman depicted within the picture plane, he asks us to consider, “What does it feel like to look like this?” (p. 21) in order to entertain our many emotional responses and interpretations. When he adds, “What does it feel like to whom?” the sexual difference of the spectator also clearly comes into play. (shrink)

This paper advances a novel argument that speech perception is a complex system best understood nonindividualistically and therefore that individualism fails as a general philosophical program for understanding cognition. The argument proceeds in four steps. First, I describe a "replaceability strategy", commonly deployed by individualists, in which one imagines replacing an object with an appropriate surrogate. This strategy conveys the appearance that relata can be substituted without changing the laws that hold within the domain. Second, I advance a "counterfactual test" (...) as an alternative to the replaceability strategy. Third, I show how the typical objects of cross-modal processes (in this case, auditory-visual speech perception), more clearly irreplaceable than the objects of the unimodal process examined by Burge [(1986) Individualism and psychology, The Philosophical Review, XCV, 3-45], supply a firm basis for a nonindividualist interpretation of such cases. Finally, I demonstrate that the routine violation of the individualist's Replaceability Condition occurs even in unimodal cases - so the violation of the replaceability constraint does not derive simply from the diversity of modal sources but rather from the causal complexity of psychological processes generally. The conclusion is that philosophical progress on this issue must await progress in psychology, or, at least, philosophical progress in accounting for psychological complexity--precisely the vicissitude predicted by a thoroughgoing naturalism.

Wittgenstein’s comment that what can be shown cannot be said has a special resonance with visual representations of power in both Heavy Metal and Fundamentalist Christian communities. Performances at metal shows, and performances of ‘religious theatre’, share an emphasis on violence and destruction. For example, groups like GWAR and Cannibal Corpse feature violent scenes in stage shows and album covers, scenes that depict gory results of unrestrained sexuality that are strikingly like Halloween ‘Hell House’ show presented by neo-Conservative, Fundamentalist (...) Christian churches in the southeastern United States’ ‘Bible Belt’. One group may claim to celebrate violence, the other sees violence as a tool to both encourage ‘moral’ behaviour, and to show that the Christian church is able to ‘speak the language’ of young people who are fans of metal, gore, and horror. Explicit violence, in each case, signifies power relationships that are in transformation. Historically, medieval morality plays and morality cycles had been used as a pedagogical tool. In the modern-day context of fundamentalist religious education, these Hell House performances seek to exclude outsiders and solidify teen membership in the Christian community. Hell House performances are marketed to the young church members, and are seen as a way to reinvigorate conservative Fundamentalist Christianity. Women and girls routinely take part in, and often organize Hell House events. In the context of heavy metal, violent performances do not seek to exclude, but provide an outlet for a variety of socially unacceptable or unpopular feelings. In each context there is an apparent, if not actual, empowering of women who are willing to play particular kinds of roles. The use of violence and gore has a value beyond merely shocking the audience, it is arguably a way that some women find their voice, both for fundamentalist Christians and fundamentalist gore metal fans.
