Previous studies have identified the critical role of the left fusiform cortex in visual word form processing, learning, and memory. However, this so-called visual word form area's other functions are not clear. In this study, we used fMRI and the subsequent memory paradigm to examine whether the putative VWFA was involved in the processing and successful memory encoding of faces as well as words. Twenty-two native Chinese speakers were recruited to memorize the (...) class='Hi'>visual forms of faces and Chinese words. Episodic memory for the studied material was tested 3. h after the scan with a recognition test. The fusiform face area and the VWFA were functionally defined using separate localizer tasks. We found that, both within and across subjects, stronger activity in the VWFA was associated with better recognition memory of both words and faces. Furthermore, activation in the VWFA did not differ significantly during the encoding of faces and words. Our results revealed the important role of the so-called VWFA in face processing and memory and supported the view that the left mid-fusiform cortex plays a general role in the successful processing and memory of different types of visual objects. © 2010 Elsevier Inc.

It has been recently argued that some machine learning techniques known as Kernel methods could be relevant for capturing cognitive and neural mechanisms (Jäkel, Schölkopf, & Wichmann, 2009). We point out that ‘‘String kernels,’’ initially designed for protein function prediction and spam detection, are virtually identical to one contending proposal for how the brain encodes orthographic information during reading. We suggest some reasons for this connection and we derive new ideas for visual word recognition that are successfully put (...) to the test. We argue that the versatility and performance of String kernels makes a compelling case for their implementation in the brain. (shrink)

Recent theological anthropology emphasizes a dynamic and integral understanding of the human being, which is also related to Karl Rahner's idea of active self-transcendence and to the imago Dei doctrine. The recent neuroscientific discovery of the “visual word form area” for reading, regarded in light of the concept of cultural neural reuse, will produce fresh implications for the interrelation of brain biology and human culture. The theological and neuroscientific parts are shown in their mutual connections thus (...) articulating the notion that human beings shape and transcend themselves both at the biological and at the cultural level. This will have relevant implications for the timely topic of human uniqueness in science and theology, and in proposing a new research perspective in which theology may consider culture along with its biological import, but not necessarily in strictly evolutionary terms alone.

Priming and recollection are expressions of human memory mediated by different brain events. These brain events were monitored while people discriminated words from nonwords. Mean response latencies were shorter for words that appeared in an earlier study phase than for new words. This priming effect was reduced when the letters of words in study-phase presentations were presented individually in succession as opposed to together as complete words. Based on this outcome, visual word-form priming was linked to a (...) brain potential recorded from the scalp over the occipital lobe about 450 ms after word onset. This potential differed from another potential previously associated with recollection, suggesting that distinct operations associated with these two types of memory can be monitored at the precise time that they occur in the human brain.

If the cortex is an associative memory, strongly connected cell assemblies will form when neurons in different cortical areas are frequently active at the same time. The cortical distributions of these assemblies must be a consequence of where in the cortex correlated neuronal activity occurred during learning. An assembly can be considered a functional unit exhibiting activity states such as full activation (“ignition”) after appropriate sensory stimulation (possibly related to perception) and continuous reverberation of excitation within the assembly (a (...) putative memory process). This has implications for cortical topographies and activity dynamics of cell assemblies forming during language acquisition, in particular for those representing words. Cortical topographies of assemblies should be related to aspects of the meaning of the words they represent, and physiological signs of cell assembly ignition should be followed by possible indicators of reverberation. The following postulates are discussed in detail: (1) assemblies representing phonological word forms are strongly lateralized and distributed over perisylvian cortices; (2) assemblies representing highly abstract words such as grammatical function words are also strongly lateralized and restricted to these perisylvian regions; (3) assemblies representing concrete content words include additional neurons in both hemispheres; (4) assemblies representing words referring to visual stimuli include neurons in visual cortices; and (5) assemblies representing words referring to actions include neurons in motor cortices. Two main sources of evidence are used to evaluate these proposals: (a) imaging studies focusing on localizing word processing in the brain, based on stimulus-triggered event-related potentials (ERPs), positron emission tomography (PET), and functional magnetic resonance imaging (fMRI), and (b) studies of the temporal dynamics of fast activity changes in the brain, as revealed by high-frequency responses recorded in the electroencephalogram (EEG) and magnetoencephalogram (MEG). These data provide evidence for processing differences between words and matched meaningless pseudowords, and between word classes, such as concrete content and abstract function words, and words evoking visual or motor associations. There is evidence for early word class-specific spreading of neuronal activity and for equally specific high-frequency responses occurring later. These results support a neurobiological model of language in the Hebbian tradition. Competing large-scale neuronal theories of language are discussed in light of the data summarized. Neurobiological perspectives on the problem of serial order of words in syntactic strings are considered in closing. Key Words: associative learning; cell assembly; cognition; cortex; ERP; EEG; fMRI; language; lexicon; MEG; PET; word category. (shrink)

In a digital era that neglects handwriting, the current study is significant because it examines the mechanisms underlying this process. We recruited 9- to 10-year-old Chinese children, who were at an important period of handwriting development, and adult college students, for both behavioral and electroencephalogram experiments. We designed four learning conditions: handwriting Chinese, viewing Chinese, drawing shapes followed by Chinese recognition, and drawing shapes followed by English recognition. Both behavioral and EEG results showed that HC facilitated visual word (...) recognition compared to VC, and behavioral results showed that HC facilitated visual word recognition compared to drawing shapes. HC and VC resulted in a lateralization of the N170 in adults, but not in children. Taken together, the results of the study suggest benefits of handwriting on the neural processing and behavioral performance in response to Chinese characters. The study results argue for maintaining handwriting practices to promote the perception of visual word forms in the digital age. (shrink)

A central component in the E-Z Reader model is a two-stage word processing mechanism made responsible for both the triggering of eye movements and sequential shifts of attention. We point to problems with both the verbal description of this mechanism and its computational implementation in the simulation. As an alternative, we consider the use of a connectionist processing module in combination with a more indirect form of cognitive eye-movement control.

The proposed volumes are aimed at a multidisciplinary audience and seek to fill the gap between law, semiotics and visuality providing a comprehensive theoretical and analytical overview of legal visual semiotics. They seek to promote an interdisciplinary debate from law, semiotics and visuality bringing together the cumulative research traditions of these related areas as a prelude to identifying fertile avenues for research going forward. Advance Praise for Law, Culture and Visual Studies This diverse and exhilarating collection of essays (...) explores the many facets both historical and contemporary of visual culture in the law. It opens a window onto the substantive, jurisdictional, disciplinary and methodological diversity of current research. It is a cornucopia of materials that will enliven legal studies for those new to the field as well as for established scholars. It is a 'must read' that will leave you wondering about the validity of the long held obsession that reduces the law and legal studies to little more than a preoccupation with the word. Leslie J Moran Professor of Law, Birkbeck College, University of London Law, Culture and Visual Studies is a treasure trove of insights on the entwined roles of legality and visuality. From multiple interdisciplinary perspectives by scholars from around the world, these pieces reflect the fullness and complexities of our visual encounters with law and culture. From pictures to places to postage stamps, from forensics to film to folklore, this anthology is an exciting journey through the fertile field of law and visual culture as well as a testament that the field has come of age. Naomi Mezey, Professor of Law, Georgetown University Law Center, Washington, D.C., USA This highly interdisciplinary reference work brings together diverse fields including cultural studies, communication theory, rhetoric, law and film studies, legal and social history, visual and legal theory, in order to document the various historical, cultural, representational and theoretical links that bind together law and the visual. This book offers a breath-taking range of resources from both well-established and newer scholars who together cover the field of law's representation in, interrogation of, and dialogue with forms of visual rhetoric, practice, and discourse. Taken together this scholarship presents state of the art research into an important and developing dimension of contemporary legal and cultural inquiry. Above all, Law Culture and Visual Studies lays the groundwork for rethinking the nature of law in our densely visual culture: How are legal meanings produced, encoded, distributed, and decoded? What critical and hermeneutic skills, new or old, familiar or unfamiliar, will be needed? Topical, diverse, and enlivening, Law Culture and Visual Studies is a vital research tool and an urgent invitation to further critical thinking in the areas so well laid out in this collection.

Stunned by the implications of Colagè's analysis of the cultural activation of the brain's Visual Word Form Area and the potential role of cultural neural reuse in the evolution of biology and culture, the authors build on his work in proposing a context for the first rudimentary hominin moral systems. They cross-reference six domains: neuroscience on sleep, creativity, plasticity, and the Left Hemisphere Interpreter; palaeobiology; cognitive science; philosophy; traditional archaeology; and cognitive archaeology's theories on sleep changes (...) in Homo erectus and consequences for later humans. The authors hypothesize that the human genome, when analyzed with findings from neuroscience and cognitive science, will confirm the evolutionary timing of an internal running monologue and other neural components that constitute moral decision making. The authors rely on practical modern philosophers to identify continuities with earlier primates, and one major discontinuity—some bright white moral line that may have been crossed more than once during the long and successful tenure of Homo erectus on Earth.

The article is devoted to the problem of changing stylistic paradigm in the Persian poetry of XVI-XVII centuries and reflection of this process in self-consciousness of outstanding authors of the period. Parallel with preserving stable norms of traditional poetics literary practice demonstrates flexibility and forms new range of popular poetic strategies. New aesthetic criteria if ideal poetic language, expressed with epithet ‘colourful’, appears alongside with criteria of previous period, expressed with epithet ‘sweet’ and step by step gets leadership. Lyric poetry (...) of three famous authors of the period of formation and golden age of Indian style served the object of analyses. The phenomena of visualization of imagery connected with perfect poetic language illustrated by examples of ‘Poet and Poetry’ motifs located in ‘frame text’ in end of the qhazal. These motifs serve one of the regular contexts of author’s name and show author’s attitude to his creation, including stylistic preferences. Refinement of poetic fantasy being declared basic condition of creating perfect poetry described visually as coiling lasso, poetry itself as flourishing garden, fountain or European house decorated with painting. Such characteristic of word creation has analogies in the works of Baroque style theorist Giambattista Marino. (shrink)

The cortical visual mechanisms involved in processing spatial relationships remain subject to debate. According to one current view, the ''dorsal stream'' of visual areas, emanating from primary visual cortex and culminating in the posterior parietal cortex, mediates this aspect of visual processing. More recently, others have argued that while the dorsal stream provides egocentric coding of visual location for motor control, the separate ''ventral'' stream is needed for allocentric spatial coding. We have assessed the (...) class='Hi'>visual form agnosic patient DF, whose lesion mainly affects the ventral stream, on a prehension task requiring allocentric spatial coding. She was presented with transparent circular disks. Each disk had circular holes cut in it. DF was asked to reach out and grasp the disk by placing her fingers through the holes. The disks either had three holes (for forefinger, middle finger, and thumb) or two holes (for forefinger and thumb). The distance between the forefinger and thumb holes, and the orientation of the line formed by them, were independently varied. DF was quite unable to adjust her grip aperture or her hand orientation in the three-hole task. Although she was able to orient her hand appropriately for the two-hole disks, she still remained unable to adjust her grip aperture to the distance between the holes. These findings are consistent with the idea that allocentric processing of spatial information requires a functioning ventral stream, even when the information is being used to guide a motor response.

This volume explores how functional brain imaging techniques like positron emission tomography have influenced cognitive studies. The first chapter outlines efforts to relate human thought and cognition in terms of great books from the late 1800s through the present. Chapter 2 describes mental operations as they are measured in cognitive science studies. It develops a framework for relating mental operations to activity in nerve cells. In Chapter 3, the PET method is reviewed and studies are presented that use PET to (...) map the striate cortex and to activate extrastriate motion, color, and form areas. Chapter 4 shows how top down processes involving attention can lead to activation of these same areas in the detection of targets, visual search, and visual imagery. This chapter reveals complex networks of activations. Chapters 5 and 6 deal with the presentation of words. Chapter 5 illustrates PET studies of the anatomy of visual word processing and shows how the circuitry used for generating novel uses of words changes as the task becomes automated. Chapter 6 applies high density electrical recording to explore these activations in real time and to show how a constant anatomy can be reprogrammed by task instructions to produce and perform different cognitive tasks. Chapter 7 shows how studies of brain lesions and PET converge on common networks underlying attentional functions such as visual orienting, target detection, and maintenance of the alert state. Chapters 8 and 9 apply the network approach to examine normal development of attention in infants and pathological conditions resulting from brain damage, and psychiatric pathologies of depression, schizophrenia, and attention deficit disorder. In Chapter 10, new developments such as functional MRI are discussed in terms of future developments and integration of cognitive neuroscience. (shrink)

Embodied theories of grounded semantics postulate that, when word meaning is first acquired, a link is established between symbol and corresponding semantic information present in modality-specific—including primary—sensorimotor cortices of the brain. Direct experimental evidence documenting the emergence of such a link, however, is still missing. Here, we present new neuroimaging results that provide such evidence. We taught participants aspects of the referential meaning of previously unknown, senseless novel spoken words by associating them with either a familiar action or a (...) familiar object. After training, we used functional magnetic resonance imaging to analyze the participants’ brain responses to the new speech items. We found that hearing the newly learnt object-related word sounds selectively triggered activity in the primary visual cortex, as well as secondary and higher visual areas.These results for the first time directly document the formation of a link between the novel, previously meaningless spoken items and corresponding semantic information in primary sensory areas in a category-specific manner, providing experimental support for perceptual accounts of word-meaning acquisition in the brain.

We investigated the effects of everyday language exposure on the prediction of orthographic and phonological forms of a highly predictable word during listening comprehension. Native Japanese speakers in Tokyo (Experiment 1) and Berlin (Experiment 2) listened to sentences that contained a predictable word and viewed four objects. The critical object represented the target word (e.g., /sakana/;fish), an orthographic competitor (e.g., /tuno/;horn), a phonological competitor (e.g., /sakura/;cherry blossom), or an unrelated word (e.g., /hon/;book). The three other objects (...) were distractors. The Tokyo group fixated the target and the orthographic competitor over the unrelated objects before the target word was mentioned, suggesting that they pre-activated the orthographic form of the target word. The Berlin group showed a weaker bias toward the target than the Tokyo group, and they showed a tendency to fixate the orthographic competitor only when the orthographic similarity was very high. Thus, prediction effects were weaker in the Berlin group than in the Tokyo group. We found no evidence for the prediction of phonological information. The obtained group differences support probabilistic models of prediction, which regard the built-up language experience as a basis of prediction. (shrink)

Evidence from adult studies of deaf signers supports the dissociation between neural systems involved in processing visual linguistic and non-linguistic body actions. The question of how and when this specialization arises is poorly understood. Visual attention to these forms is likely to change with age and be affected by prior language experience. The present study used eye-tracking methodology with infants and children as they freely viewed alternating video sequences of lexical American sign language (ASL) signs and non-linguistic body (...) actions (self-directed grooming action and object-directed pantomime). In Experiment 1, we quantified fixation patterns using an area of interest (AOI) approach and calculated face preference index (FPI) values to assess the developmental differences between 6 and 11-month-old hearing infants. Both groups were from monolingual English-speaking homes with no prior exposure to sign language. Six-month-olds attended the signer’s face for grooming; but for mimes and signs, they were drawn to attend to the “articulatory space” where the hands and arms primarily fall. Eleven-month-olds, on the other hand, showed a similar attention to the face for all body action types. We interpret this to reflect an early visual language sensitivity that diminishes with age, just before the child’s first birthday. In Experiment 2, we contrasted 18 hearing monolingual English-speaking children (mean age of 4.8 years) vs. 13 hearing children of deaf adults (CODAs; mean age of 5.7 years) whose primary language at home was ASL. Native signing children had a significantly greater face attentional bias than non-signing children for ASL signs, but not for grooming and mimes. The differences in the visual attention patterns that are contingent on age (in infants) and language experience (in children) may be related to both linguistic specialization over time and the emerging awareness of communicative gestural acts.

Advances in neuroscience implicate reentrant signaling as the predominant form of communication between brain areas. This principle was used in a series of masking experiments that defy explanation by feed-forward theories. The masking occurs when a brief display of target plus mask is continued with the mask alone. Two masking processes were found: an early process affected by physical factors such as adapting luminance and a later process affected by attentional factors such as set size. This later process is (...) called masking by object substitution, because it occurs whenever there is a mismatch between the reentrant visual representation and the ongoing lower level activity. Iterative reentrant processing was formalized in a computational model that provides an excellent fit to the data. The model provides a more comprehensive account of all forms of visual masking than do the long-held feed-forward views based on inhibitory contour interactions. (shrink)

In this article we present a new experimental paradigm: comparative visual search. Each half of a display contains simple geometrical objects of three different colors and forms. The two display halves are identical except for one object mismatched in either color or form. The subject's task is to find this mismatch. We illustrate the potential of this paradigm for investigating the underlying complex processes of perception and cognition by means of an eye‐tracking study. Three possible search strategies are (...) outlined, discussed, and reexamined on the basis of experimental results. Each strategy is characterized by the way it partitions the field of objects into “chunks.” These strategies are: (i) Stimulus‐wise scanning with minimization of total scan path length (a “traveling salesman” strategy), (ii) scanning of the objects in fixed‐size areas (a “searchlight” strategy), and (iii) scanning of object sets based on variably sized clusters defined by object density and heterogeneity (a “clustering” strategy). To elucidate the processes underlying comparative visual search, we introduce besides object density a new entropy‐based measure for object heterogeneity. The effects of local density and entropy on several basic and derived eye‐movement variables clearly rule out the traveling salesman strategy, but are most compatible with the clustering strategy.

Visual imagery is a form of sensory imagination, involving subjective experiences typically described as similar to perception, but which occur in the absence of corresponding external stimuli. We used the Activation Likelihood Estimation algorithm (ALE) to identify regions consistently activated by visual imagery across 40 neuroimaging studies, the first such meta-analysis. We also employed a recently developed multi-modal parcellation of the human brain to attribute stereotactic co-ordinates to one of 180 anatomical regions, the first time this approach (...) has been combined with the ALE algorithm. We identified a total 634 foci, based on measurements from 464 participants. Our overall comparison identified activation in the superior parietal lobule, particularly in the left hemisphere, consistent with the proposed ‘top-down’ role for this brain region in imagery. Inferior premotor areas and the inferior frontal sulcus were reliably activated, a finding consistent with the prominent semantic demands made by many visual imagery tasks. We observed bilateral activation in several areas associated with the integration of eye movements and visual information, including the supplementary and cingulate eye fields (SCEFs) and the frontal eye fields (FEFs), suggesting that enactive processes are important in visual imagery. V1 was typically activated during visual imagery, even when participants have their eyes closed, consistent with influential depictive theories of visual imagery. Temporal lobe activation was restricted to area PH and regions of the fusiform gyrus, adjacent to the fusiform face complex (FFC). These results provide a secure foundation for future work to characterise in greater detail the functional contributions of specific areas to visual imagery. (shrink)

Although the study of visual perception has made more progress in the past 40 years than any other area of cognitive science, there remain major disagreements as to how closely vision is tied to general cognition. This paper sets out some of the arguments for both sides and defends the position that an important part of visual perception, which may be called early vision or just vision, is prohibited from accessing relevant expectations, knowledge and utilities - in (...) other words it is cognitively impenetrable. That part of vision is complex and articulated and provides a representation of the 3-D surfaces of objects sufficient to serve as an index into memory, with somewhat different outputs being made available to other systems such as those dealing with motor control. The paper also addresses certain conceptual and methodological issues, including the use of signal detection theory and event-related potentials to assess cognitive penetration of vision. A distinction is made among several stages in visual processing. These include, in addition to the inflexible early-vision stage, a pre-perceptual attention allocation stage and a post-perceptual evaluation, memory-accessing, and inference stage which provide several different highly constrained ways in which cognition can affect the outcome of visual perception. The paper discusses arguments that have been presented in both computer vision and psychology showing that vision is "intelligent" and involves elements of problem solving". It is suggested that these cases do not show cognitive penetration, but rather they show that certain natural constraints on interpretation, concerned primarily with optical and geometrical properties of the world, have been compiled into the visual system. The paper also examines a number of examples where instructions and "hints" are alleged to affect. (shrink)

The past twenty years have witnessed extensive collaborative research between computer scientists, logicians, linguists, philosophers, and psychologists. These interdisciplinary studies stem from the realization that researchers drawn from all fields are studying the same problem. Specifically, a common concern amongst researchers today is how logic sheds light on the nature of information. Ancient questions concerning how humans communicate, reason and decide, and modern questions about how computers should communicate, reason and decide are of prime interest to researchers in various disciplines. (...) _Words, Proofs and Diagrams_ is a collection of papers covering active research areas at the interface of logic, computer science, and linguistics. Readers of the volume will find traditional research on process logics, issues in formal semantics, and language processing. In addition, the volume also highlights a particularly new area where all three disciplines meet—the study of images and graphics as information carriers and the diagrammatic reasoning supported by them.

The present volume consists of diverse individual texts, produced between 1980 and 1986, which take two forms: interviews in which Bourdieu confronts a series of probing and intelligent interviewers, and conference papers that clarify and extend specific areas of his research. Now that Bourdieu's work has achieved wide diffusion and celebrity, this is an appropriate time for this volume, a pause for retrospection and resynthesis, for corrections of misreadings and extension of previous insights, and for projection of the next stages (...) of his work. For this English edition, Bourdieu's celebrated inaugural lecture at the Collège de France, Leçon sur la Leçon, has been added. The texts fall into two fundamental areas. The first area provides an overview of Bourdieu's central concepts, never before clearly explained. The second area clarifies the philosophical presuppositions of Bourdieu's studies and gives an account of his relations with the series of thinkers who formulated the problems in social and cultural theory that still preoccupy us: Kant, Hegel, Marx, Durkheim, Wittgenstein, Weber, Parsons, and Lévi-Strauss. Bourdieu's visions of these figures is personal and penetrating, and in his vivacious, spontaneous responses one sees at work a mode of thought that can in itself be a liberating tool of social analysis. Bourdieu applies to himself the method of analyzing cultural works that he expounds, evoking the space of theoretical possibilities presented to him at different moments of his intellectual itinerary.

Previous research on associative learning has uncovered detailed aspects of the process, including what types of things are learned, how they are learned, and where in the brain such learning occurs. However, perceptual processes, such as stimulus recognition and identification, take time to unfold. Previous studies of learning have not addressed when, during the course of these dynamic recognition processes, learned representations are formed and updated. If learned representations are formed and updated while recognition is ongoing, the result of learning (...) may incorporate spurious, partial information. For example, during word recognition, words take time to be identified, and competing words are often active in parallel. If learning proceeds before this competition resolves, representations may be influenced by the preliminary activations present at the time of learning. In three experiments using word learning as a model domain, we provide evidence that learning reflects the ongoing dynamics of auditory and visual processing during a learning event. These results show that learning can occur before stimulus recognition processes are complete; learning does not wait for ongoing perceptual processing to complete. (shrink)

''As a text in developmental psychology the book is excellent, and this lower-priced paperback version will be snapped up by psychology students.'' -European NeurologyOne of the most dramatic areas of development in early human life is that of vision. Whereas vision plays a relatively minor role in the world of the newborn infant, by 6 months it has assumed the position as a dominant sense and forms the basis of later perceptual, cognitive, and social development. From a world leader in (...) the study of visual development in human infants comes a major new work, condensing a lifetime of work in this area - The developing visual brain. Drawing on over 20 years of cutting edge research in the Visual Develoment Units in Cambridge and University College London, the book provides the definitive account of what we know about the developing visual system, and the problems that can occur during development. The book reviews, evaluates, and sets in context the exciting progress being made in this area, and additionally suggests new areas for research. Written to be accessible for advanced undergraduates, graduate students, and researchers in psychology, the neurosciences, optometry, and visual science, The developing visual brain represents an important new addition to the literature on vision.

Number processing abilities are important for academic and personal development. The course of initial specialization of ventral occipito-temporal cortex sensitivity to visual number processing is crucial for the acquisition of numeric and arithmetic skills. We examined the visual N1, the electrophysiological correlate of vOTC activation across five time points in kindergarten, middle and end of first grade, second grade, and fifth grade. A combination of cross-sectional and longitudinal EEG data of a total of 62 children at varying familial (...) risk for dyslexia were available to form groups of 23, 22, 27, 27, and 42 participants for each of the five time points. The children performed a target detection task which included visual presentation of single digits, false fonts, and letters to derive measures for coarse and fine digit sensitive processing across development. The N1 amplitude analyses indicated coarse and fine sensitivity characterized by a stronger N1 to digits than false fonts across all five time points, and stronger N1 to digits than letters at all but the second time point. In addition, lower arithmetic skills were associated with stronger coarse N1 digit sensitivity over the left hemisphere in second grade, possibly reflecting allocation of more attentional resources or stronger reliance on the verbal system in children with poorer arithmetic skills. To summarize, our results show persistent visual N1 sensitivity to digits that is already present early on in pre-school and remains stable until fifth grade. This pattern of digit sensitivity development clearly differs from the relatively sharp rise and fall of the visual N1 sensitivity to words or letters between kindergarten and middle of elementary school and suggests unique developmental trajectories for visual processing of written characters that are relevant to numeracy and literacy.

David Houston Jones builds a bridge between practices conventionally understood as forensic, such as crime scene investigation, and the broader field of activity which the forensic now designates, for example performance and installation art, as well as photography. Contemporary work in these areas responds both to forensic evidence, including crime scene photography, and to some of the assumptions underpinning its consumption. It asks how we look, and in whose name, foregrounding and scrutinising the enduring presence of voyeurism in visual (...) media and instituting new forms of ethical engagement. Such work responds to the object-oriented culture associated with the forensic and offers a reassessment of the relationship of human voice and material evidence. It displays an enduring debt to the discursive model of testimony which has so far been insufficiently recognised, and which forms the basis for a new ethical understanding of the forensic. Jones's analysis brings this methodology to bear upon a strand of contemporary visual activity which has the power to significantly redefine our understandings of the production, analysis and deployment of evidence. Artists examined include Forensic Architecture, Simon Norfolk, Melanie Pullen, Angela Strassheim, John Gerrard, Julian Charrière, Trevor Paglen, Laura Poitras and Sophie Ristelhueber. The book will be of interest to scholars working in art history, visual culture, literary studies, modern languages, photography and critical theory. (shrink)

The sounds that make up spoken words are heard in a series and must be mapped rapidly onto words in memory because their elements, unlike those of visual words, cannot simultaneously exist or persist in time. Although theories agree that the dynamics of spoken word recognition are important, they differ in how they treat the nature of the competitor set—precisely which words are activated as an auditory word form unfolds in real time. This study used eye (...) tracking to measure the impact over time of word frequency and 2 partially overlapping competitor set definitions: onset density and neighborhood density. Time course measures revealed early and continuous effects of frequency (facilitatory) and on set based similarity (inhibitory). Neighborhood density appears to have early facilitatory effects and late inhibitory effects. The late inhibitory effects are due to differences in the temporal distribution of similarity within neighborhoods. The early facilitatory effects are due to subphonemic cues that inform the listener about word length before the entire word is heard. The results support a new conception of lexical competition neighborhoods in which recognition occurs against a background of activated competitors that changes over time based on fine-grained goodness-of-fit and competition dynamics.

In this event-related potential study a masking technique that prevents conscious perception of words and non-words through attentional distraction was used to reveal the temporal dynamics of word processing under non-conscious and conscious conditions. In the non-conscious condition, ERP responses differed between masked words and non-words from 112 to 160 ms after stimulus-onset over posterior brain areas. The early onset of the word–non-word differences was compatible with previous studies that reported non-conscious access to orthographic information within this (...) time period. Moreover, source localisations provided evidence for automatic activation of prelexical phonological information, whereas no evidence for non-conscious semantic processing was found. When subjects were informed about the masking technique, lexical differences occurred at later time intervals, suggesting conscious access to additional word related information. These results indicate that early visual word processing does not depend entirely on attentional resources, but that non-conscious processing probably is restricted to rather lower-level linguistic information.

Usage-based linguistics postulates that multi-word expressions constitute a substantial part of language structure and use, and are formed through repeated chunking and stored as exemplar wholes. They are also re-used to produce new sequences by means of schematization. While there is extensive research on multi-word expressions in many spoken languages, little is known about the status of multi-word expressions in the mainstream U.S. variety of American Sign Language. This paper investigates recurring multi-word expressions, or sequences of (...) multiple signs, that involve a high-frequency sign of visual perception glossed as look and the family of ‘look’ signs. The look sign exhibits two broad functions: look/‘vision’ references literal or metaphorical vision and look/‘reaction’ signals a person’s reaction to a visual stimulus. Data analysis reveals that there are recurring sequences in distinct syntactic environments associated with the two functions of look, suggesting that look is in the process of grammaticalization from a verb of visual perception to a stance verb. The sequences demonstrate the emergence of linguistic structure from repeated use through the domain-general cognitive process of chunking in ASL. (shrink)

The early facilitatory effects are due to subphonemic cues that inform the listener about word length before the entire word is heard. The results support a new conception of lexical competition neighborhoods in which recognition occurs against a background of activated competitors that changes over time based on fine‐grained goodness‐of‐fit and competition dynamics.

Do properties of a word's features influence the order of its acquisition in early word learning? Combining the principles of mutual exclusivity and shape bias, the present work takes a network analysis approach to understanding how feature distinctiveness predicts the order of early word learning. Distance networks were built from nouns with edge lengths computed using various distance measures. Feature distinctiveness was computed as a distance measure, showing how far an object in a network is from other (...) objects based on shared and non-shared features. Feature distinctiveness predicted order of acquisition across all measures: Words that were further away from other words in the network space were learned earlier. The best distance measures were based only on non-shared features and did not include shared features. This indicates that shared features may play less of a role in early word learning than non-shared features. In addition, the strongest effects were found for visual form and surface features. Cluster analysis further revealed that this effect is a localized effect in the object feature space, where objects' distances from their cluster centroid were inversely correlated with their age of acquisition. Together, these results suggest a role for feature distinctiveness in early word learning. (shrink)

The links which connect the nature of the medium to the methods of access and to the objects of knowledge, relationships between form and content, are a broad continuum whose interlinked facts require a transdisciplinary study.Nowadays, attempts to discern these links seem to concern two central groups of correlations, which have been analysed from the perspective of different disciplines.In the foreground of correlations we find the relationship between the material characteristics of the mediums and the methods of access to (...) their contents; in this field of cultural technologies, the history of verbal language is punctuated first by the ‘invention’ of writing and its different systems, then by a series of transformations of manuscripts and the printed word, and finally by electronic communication. In the study of this first relationship, the history, psychology and physiology of reading establish a relationship between several parameters: on the one hand, the system of signs and spaces in the organization of the written code, and on the other hand, the methods of appropriation of this code by the reader (both reading aloud and silent reading), linear progression or freedom of selection of the contents, degree of speed, amount of information” habits of memorization, etc. (shrink)

Philosophers have long agreed that thinking is expressed in the use of language, that we “think in the medium of words.” It is also true, however, that we think in the medium of pictures, and it is likely that these two ways of thinking are interrelated; certainly, we could not think in pictures if we did not have words, and perhaps we could not use words, in principle, unless we were also engaged in some sort of picturing, at least in (...) our imagination. An ideographic language like Chinese would give greater support to the latter possibility than would our phonetically based form of writing. (shrink)

This text focuses from a philological perspective on media theories and their impact on traditional text-based disciplines. Therefore it looks at the problems that have emerged for Media Studies as well as for traditional studies in philology when reflecting on the concept of self-reference, since their subjects can seemingly no longer rely on the purity of the written word. If research work in the field of humanities is still mainly documented by texts, how does the advance of images as (...) a challenging research subject affect the text that is referring to that subject? Speaking in media terms: how is the medium `text', which still remains text when it is concerned with the medium `image', affected by the `other' medium? This question deals with the problem of self-reference, hence the construction of disciplinary limitations in various academic fields. Beginning with this question, I try to find out how the difference between self-reference and reference has been and still is being organized in texts. How can we compare different types of theorizing images in texts? These abstract problems will be exemplified by situating the word—image bias in a wider historical context. The text concludes by developing some possibilities for future research within this area of visual culture and academic writing. (shrink)

The neural substrates of context effects in word perception are still largely unclear. Interhemispheric priming phenomena in word recognition, typically observed in normal subjects, are absent in commissurotomized patients. This suggests that callosal fibers may provide contextual integration. In addition, certain characteristics of human frontal cortical fields subserving sensorimotor learning, as investigated by positron emission tomography, provide evidence for contextual integration not confined to the visual system. This supports the notion of common aspects of cortical computations in (...) different cerebral areas. (shrink)

Do properties of a word's features influence the order of its acquisition in early word learning? Combining the principles of mutual exclusivity and shape bias, the present work takes a network analysis approach to understanding how feature distinctiveness predicts the order of early word learning. Distance networks were built from nouns with edge lengths computed using various distance measures. Feature distinctiveness was computed as a distance measure, showing how far an object in a network is from other (...) objects based on shared and non‐shared features. Feature distinctiveness predicted order of acquisition across all measures: Words that were further away from other words in the network space were learned earlier. The best distance measures were based only on non‐shared features (object dissimilarity) and did not include shared features (object similarity). This indicates that shared features may play less of a role in early word learning than non‐shared features. In addition, the strongest effects were found for visual form and surface features. Cluster analysis further revealed that this effect is a localized effect in the object feature space, where objects' distances from their cluster centroid were inversely correlated with their age of acquisition.

In Quarles' world the emblem as traditionally conceived must strain across a widening gap between the verbal and the visual. Rosemary Freeman's criticism of Quarles, that in a mechanical "imposition of meaning" the text of the emblem applies an interpretation to, rather than discovers a significance within, the image, is more apt than Freeman realized. With the semantic congruence between word and image no longer guaranteed, artists attempting to yoke the two would have to reconceive the relationship between (...) them. Seen as a response to this need, Blake's illuminated books complicate the emblem tradition in an art of dazzling improvisatory juxtapositions. Indeed, his revaluation of the ties between "body" and "soul" may be taken in one sense as a revision of the emblematist's traditional distinction. Words, once the soul of the emblem, now become truly animate for Blake - flowing, sprouting, multicolored - while their quirky energy, no longer restrained by standardized print, is embodied on sensual, quasi-pictorial shapes; images speak in a new and private vocabulary of emblematic birds, curling tendrils, and other forms that gesture allusively from plate to plate. These frame, underscore, celebrate, intrude upon, parody, or oppose themselves by "contraries" to the meaning of the adjoining text. If Quarles' work signals the failure of the emblem in England, its success in probing the problems of combining language and imagery points toward the renewal of the form in Blake. Ernest B. Gilman, assistant professor of English at the University of Virginia, is the author of The Curious Perspective. He is currently working on a book on joint literary and pictorial forms in the Renaissance. (shrink)

Bayes’ formula is a fundamental statistical method for inference judgments in uncertain situations used by both laymen and professionals. However, since people often fail in situations where Bayes’ formula can be applied, how to improve their performance in Bayesian situations is a crucial question. We based our research on a widely accepted beneficial strategy in Bayesian situations, representing the statistical information in the form of natural frequencies. In addition to this numerical format, we used five visualizations: a 2×2-table, a (...) unit square, an icon array, a tree diagram, and a double-tree diagram. In an experiment with 688 undergraduate students, we empirically investigated the effectiveness of three graphical properties of visualizations: area-proportionality, use of discrete and countable statistical entities, and graphical transparency of the nested-sets structure. We found no additional beneficial effect of area-proportionality. In contrast, the representation of discrete objects seems to be beneficial. Furthermore, our results show a strong facilitating effect of making the nested-sets structure of a Bayesian situation graphically transparent. Our results contribute to answering the questions of how and why a visualization could facilitate judgment and decision making in situations of uncertainty. (shrink)

Word learning is basic to foreign language acquisition, however time consuming and not always successful. Empirical studies have shown that traditional (visual) word learning can be enhanced by gestures. The gesture benefit has been attributed to depth of encoding. Gestures can lead to depth of encoding because they trigger semantic processing and sensorimotor enrichment of the novel word. However, the neural underpinning of depth of encoding is still unclear. Here, we combined an fMRI and a behavioral (...) study to investigate word encoding online. In the scanner, participants encoded 30 novel words of an artificial language created for experimental purposes and their translation into the subjects’ native language. Participants encoded the words three times visually, audiovisually, and by additionally observing semantically related gestures performed by an actress. Hemodynamic activity during word encoding revealed the recruitment of cortical areas involved in stimulus processing. In this study, depth of encoding can be spelt out in terms of sensorimotor brain networks that grow larger the more sensory modalities are linked to the novel word. Word retention outside the scanner documented a positive effect of gestures in a free recall test in the short-term. (shrink)

The Emergence of Word-Meaning in Early China makes an innovative contribution to studies of language by historicizing the Chinese notion that words have "meaning" (content independent of instances of use). Rather than presuming that the concept of word-meaning had always existed, Jane Geaney explains how and why it arose in China. To account for why a normative term (yi, "duty, morality, appropriateness") came to be used for "meanings" found in dictionaries, Geaney examines interrelated patterns of word usage (...) threading through and across a wide range of genres. These patterns show that by the first millennium, as textual production exploded—and as radically different writing forms (in Buddhist sutras) were encountered—yi already functioned as an externally accessible "model" for semantic interpretation of texts and sayings. The book has far-reaching implications. Because the idea of word-meaning is fundamental to theorizing, the book illuminates not only semantic ideas and the normativity of language in Early China, but also aspects of early Chinese philosophy and intellectual history. As the internet supplants one form of media (print), thereby reducing knowledge to vast digital databases, so too, this book explains, two thousand years ago a culture that prized oral and visual balance became an "empire of the text.".

We discuss a visual blackboard architecture that could be involved in imagery. In this architecture, networks that process identity information interact with networks that process location information, in a manner that produces structural (compositional) forms of representation. Architectures of this kind can be identified in the visual cortex, but perhaps also in prefrontal cortex areas related with working memory.

Although the notion of spatiality has always lurked in the background of discussions of literary form, the self-conscious use of the term as a critical concept is generally traced to Joseph Frank's seminal essay of 1945, "Spatial Form in Modern Literature."1 Frank's basic argument is that modernist literary works are "spatial" insofar as they replace history and narrative sequence with a sense of mythic simultaneity and disrupt the normal continuities of English prose with disjunctive syntactic arrangements. This argument (...) has been attacked on several fronts. An almost universal objection is that spatial form is a "mere metaphor" which has been given misplaced concreteness and that it denies the essentially temporal nature of literature. Some critics will concede that the metaphor contains a half-truth, but one which is likely to distract attention from more important features of the reading experience. The most polemical attacks have come from those who regard spatial form as an actual, but highly regrettable, characteristic of modern literature and who have linked it with antihistorical and even fascist ideologies.2 Advocates of Frank's position, on the other hand, have generally been content to extrapolate his premises rather than criticize them, and have compiled an ever-mounting list of modernist texts which can be seen, in some sense, as "antitemporal." The whole debate can best be advanced, in my view, not by some patchwork compromise among the conflicting claims but by a radical, even outrageous statement of the basic hypothesis in its most general form. I propose, therefore, that far from being a unique phenomenon of some modern literature, and far from being restricted to the features which Frank identifies in those works , spatial form is a crucial aspect of the experience and interpretation of literature in all ages and cultures. The burden of proof, in other words, is not on Frank to show that some works have spatial form but on his critics to provide an example of any work that does not. · 1. Frank's essay first appeared in Sewanee Review 53 and was revised in his The Widening Gyre . Frank's basic argument has not changed essentially even in his most avante-garde statements; he still regards spatial form "as a particular phenomenon of modern avante-garde writing." See "Spatial Form: An Answer to Critics," Critical Inquiry 4 : 231-52. A useful bibliography, "Space and Spatial Form in Narrative," is being complied by Jeffrey Smitten .· 2. This charge generally links the notion of spatial form with Wyndham Lewis and Ezra Pound, the imagist movement, the "irrationality" and pessimistic antihistoricism of modernism, and the conservative Romantic tradition. Frank discusses the complex motives behind these associations in the work of Robert Weimann and Frank Kermode in his "Answer to Critics," pp. 238-48. W. J. T. Mitchell, editor of Critical Inquiry, is the author of Blake's Composite Art, and The Last Dinosaur Book: The Life and Times of a Cultural Icon. The present essay is part of Iconology: The Image in Literature and the Visual Arts. "Diagrammatology" appeared in the Spring 1981 issue of Critical Inquiry. Leon Surette responds to the current essay in "‘Rational Form in Literature’". (shrink)

Variability is pervasive in spoken language, in particular if one is exposed to two varieties of the same language. Unlike in bilingual settings, standard and dialectal forms are often phonologically related, increasing the variability in word forms. We investigate whether dialectal variability in children’s input affects their ability to recognize words in Standard German, testing non-dialectal vs. dialectal children. Non-dialectal children, who typically grow up in urban areas, mostly hear Standard German forms, and hence encounter little segmental variability in (...) their input. Dialectal children in turn, who typically grow up in rural areas, hear both Standard German and dialectal forms, and are hence exposed to a large amount of variability in their input. We employ the familiar word paradigm for German children aged 12–18 months. Since dialectal children from rural areas are hard to recruit for laboratory studies, we programmed an App that allows all parents to test their children at home. Looking times to familiar vs. non-familiar words were analyzed using a semi-automatic procedure based on neural networks. Our results replicate the familiarity preference for non-dialectal German 12–18-month-old children. Non-dialectal children in the same age range, on the other hand, showed a novelty preference. One explanation for the novelty preference in dialectal children may be more mature linguistic processing, caused by more variability of word forms in the input. This linguistic maturation hypothesis is addressed in Experiment 2, in which we tested older children. These children, who are not exposed to dialectal forms, also showed a novelty preference. Taken together, our findings show that both dialectal and non-dialectal German children recognized the familiar Standard German word forms, but their looking pattern differed as a function of the variability in the input. Frequent exposure to both dialectal and Standard German word forms may hence have affected the nature of lexical representations, leading to more mature processing capacities. (shrink)
