Available in PDF, EPUB and Kindle. Book excerpt: Selective attention, the ability to focus on key information and filter out noise, is crucial for navigating the cluttered world. The neural basis of selective attention has been widely studied in the adult brain. However, much less is known about how selective attention operates and develops in children's brain. Using neuroimaging, this dissertation investigates visuo-spatial selective attention in school children (ages 6 to 12). It employs a framework that is grounded in biased competition theory in order to probe each part of the neural mechanisms underlying selective attention functions. The first study demonstrates sensory competition in children's visual cortex, providing a foundation for investigations of sensory-driven and goal-driven mechanisms that modulate the competition. The second study examines the extent to which children's visual system can use perceptual grouping principles, as one of the sensory-driven mechanisms. Evidence suggests that perceptual grouping in visual cortex continues to refine beyond age 6, which could serve as a bottleneck for efficient selective processing. The third study shows that the fronto-parietal attention network, a source of goal-driven attention control, matures by achieving a balance between the two hemispheres. Using a perceptual line bisection task, it demonstrates that children in early elementary grades (ages 6 to 8) show an attention bias towards the left-hand side of space, which gradually diminishes and becomes adult-like by middle school ages (ages 11 to 13). It also shows that the degree of spatial bias is linked to functional connectivity patterns within each child's attention network. Interestingly, such leftward biases in children are related to their reading fluency, suggesting an interaction between the attention network and the reading network across development. Together, this work demonstrates that the development of visuo-spatial selective attention in childhood is a dynamic process that is shaped by sensory processing and cognitive skills that continue to change throughout this age range. Interactions with perceptual functions and newly acquired cognitive skills should be addressed in order to better characterize the typical and atypical development of visuo-spatial selective attention.

Available in PDF, EPUB and Kindle. Book excerpt: Attention is a fundamental cognitive process that attempts to select relevant stimuli from among irrelevant distractors. Attention is altered in several neuro-psychiatric conditions such as anxiety and trauma-related disorders, in which fear also plays an important role. Thus, the study of the interaction between attention and fear could help us to understand the pathophysiology of highly prevalent and disabling conditions such as posttraumatic stress disorder (PTSD). For many years, the neural mechanisms of visuo-spatial attention have been studied by measuring the N2pc component of the event-related potential (ERP) waveform. A newer attention-related neural signal is lateralized alpha-band activity. Although both the N2pc component and lateralized alpha-band activity are considered markers of attention and are obtained by examining lateralizations in electroencephalographic signals, no prior research has examined whether these two measures reflect the same or different neural mechanisms of visuo-spatial attention. In a series of experiments, we found that the N2pc and the lateralized alpha-band are separate, dissociable signatures of visual attention. To begin to link attention and fear using ERPs, we conducted a study to develop a new ERP approach to measure fear learning using the late positive potential (LPP). We found that the LPP was a sensitive marker of fear conditioning and that it has several advantages over the traditional measure, the skin conductance response (SCR). Finally, using an attentional paradigm in which targets and distractors were associated with fear, we provided evidence supporting the hypothesis that fear-induced arousal modulates spatial attention in a generalized manner. These results not only provide new insights for understanding the basic neural processes underlying visuo-spatial attention but also allow us to have better models of the interaction between attention and fear, which may someday be useful to help patients suffering from anxiety and trauma-related disorders.

Available in PDF, EPUB and Kindle. Book excerpt: As our current understanding of the mechanisms of attentional orienting is based primarily on studies with adults, I set out to track normal and abnormal development of visuospatial attentional orienting. To that end, I examined typically developing individuals, and individuals with one of two developmental disorders-Specific Language Impairment (SLI), or Williams Syndrome (WS)--on one task assessing visual discrimination, and another, wherein accurate performance additionally requires attentional orienting. The latter task, patterned after Posner's cuing paradigm, reveals patterns of attentional shift and disengagement, and the 'benefits' and 'costs' of attentional orienting. An initial study examined 200 typically developing children (7-17 yrs) and 40 young adults (18-40 yrs), and found gradual improvement from 7 to 18 years in (a) the speed and efficiency of attentional orienting, and (b) the efficiency of disengaging attention, and processing stimuli in unattended locations. A second study examined 15 children (7-15 yrs) with SLI. Though known for their significant language problems in the absence of hearing impairment, low nonverbal IQ, social-emotional disorder or frank neurological damage, SLI individuals also exhibit 'less specific' perceptual and motor deficits, presumably due to generalized slowness in processing. Since the covert movement of attention relies on rapid neurocognitive processes, I expected this to be adversely affected in SLI. While the SLI group displayed slowed visual processing and motor responses relative to age-matched controls, the speed of their visuospatial attentional orienting was normal. A third study examined 16 individuals (16-47 yrs) with WS, who have the mental age of young children, however with relative strengths in language and face processing and profound deficits in visuospatial processing. Moreover, as WS brains have anomalies primarily in dorsal-posterior areas, including the parietal cortex and cerebellum (both implicated in attention), I hypothesized that WS visuospatial attentional orienting might be impaired. WS performance on the attention test was severely compromised, although they did demonstrate use of attentional cues to direct their behavior. Together, my data illustrate age-related changes in the efficiency and speed of components of visuospatial attentional orienting during the school-age years. These changes appear to be unaffected in SLI and arrested in WS.

Book excerpt: Elucidating the neural bases of selective attention continues to be a key challenge for psychologists, vision scientists and cognitive neuroscientists. It also represents an essential aim in translational efforts to measure, treat and prevent visual and attentional deficits, to improve teaching and learning, and to tailor automated situational awareness and alerting systems to human capabilities. Past human functional magnetic resonance imaging (fMRI) and electroencephalographic (EEG) studies, as well as animal electrophysiological studies, have provided considerable information about the temporal properties, neuroanatomical substrates, and cellular- and synaptic-level mechanisms underlying attention. Despite substantial convergence in the mechanisms of attention revealed by these different approaches, there remain significant unresolved quandaries in the scientific literature. In particular, it is currently debated whether attention can influence neural activity during the initial feedforward wave of visual processing in human primary visual cortex (V1). FMRI in humans and cellular recordings in monkeys both suggest spatial attention can influence afferent sensory processing in V1. In sharp contrast, however, such effects of attention have not been reliably reported for human EEG recordings; the short-latency C1 component of the visually evoked event-related potential (ERP) that is generated in V1 is typically not affected by selective attention. Given the fMRI findings and the animal studies, what can explain this discrepancy? FMRI activations are tied to slow changes in cerebral hemodynamics that cannot distinguish between attention effects on incoming signals and activations due to longer-latency feedback activation of V1 from higher stages of visual processing—therefore, fMRI evidence is equivocal regarding whether attention-related V1 activations represent modulations of feedforward or feedback V1 activity. However, human and animal electrophysiology both provide the temporal resolution to distinguished between initial afferent volleys and feedback activity, making it difficult to reconcile the positive findings in monkeys and the negative findings in humans. The overarching hypothesis of this dissertation is that differences in the methods and paradigms between monkey and human studies could contribute to the differences in attention effects in V1. Specifically, monkey studies typically use continuous stimulation that is arguably more similar to natural vision than the punctate stimulation paradigms (e.g., trial-by-trial spatial cuing) often used in humans to study the effects of attention on sensory processing. Ongoing stimulation may trigger attention-related feedback signals from higher areas onto V1 that might not arise, or might not be observable, when simple, single, isolated stimuli are used. To investigate whether the nature of ongoing visual stimulation may account for some of the discrepancies reported in the literature, this dissertation examines human ERPs recorded during selective attention in six variations of a novel spatial attention task that builds on a paradigm successfully used to reveal V1 attention effects in nonhuman primates. Using this task, significant effects of spatial attention were observed on the amplitude of the C1 ERP in humans (Chapter 2). The addition of high-resolution eye gaze monitoring, however, demonstrated that small, systematic deviations of eye gaze in the direction of the cue hemifield likely contributed to the Chapter 2 finding, and when data from trials with deviations of eye gaze were eliminated, no attentional modulation on the C1 ERP remained (Chapter 3). Therefore, the main hypothesis that stimulus-triggered feedback attentional modulation of V1 signals should be observed as changes in C1 ERP amplitude, was not supported. Although the present findings do not explain the differences between spatial attention effects in monkey and human V1, they do provide additional support for the model that spatial attention effects observed using fMRI in humans is likely not the result of changes in input signal processing in V1, but instead reflects later recurrent activation of V1 that serves other computational purposes.

Available in PDF, EPUB and Kindle. Book excerpt: In typical child development, attention controls many aspects of learning, including memory, motor control, and problem solving. Attention organizes the constant influx of information that needs to be absorbed by children. Inside Visual Attention in Children: Theories and Activities, Dr. Kenneth A. Lane describes the positive aspects of attention that are needed for children to be successful in the classroom, such as concentration and vigilance, as opposed to negative aspects that can lead to failure, such as distractibility and confusion. This book is divided into two parts. The first eight chapters of the book explain attention and its relationship to vision and visual stimuli. The core topics discussed here include Autism, ADHD, Dyslexia, Executive Function, and Memory. The second half outlines a Vision Therapy program and consists of activities for improving visual attention in children. Over 100 activities are explained and illustrated. Visual Attention in Children: Theories and Activities is anchored on current theories in five areas of attention that shape child development. Theories Described Include: Focused Attention – The ability to respond discreetly to visual, auditory, and tactile stimuli Selective Attention – The ability to maintain behavioral or cognitive abilities in the face of distracting or competing stimuli Shifting Attention – The ability to rapidly shift attention from one object to another Sustained Attention – The ability to maintain a consistent behavioral response during a continuous or repetitive activity Divided Attention –The ability to engage in more than one attention-focused task at one time Visual Attention in Children: Theories and Activities is the perfect tool for occupational therapy students and clinicians as well as other professionals specializing in child development and learning who are looking to enhance their understanding of this topic and who need unique ideas and activities to add to their visual therapy training programs.

Book excerpt: The second edition of an essential resource to the evolving field of developmental cognitive neuroscience, completely revised, with expanded emphasis on social neuroscience, clinical disorders, and imaging genomics. The publication of the second edition of this handbook testifies to the rapid evolution of developmental cognitive neuroscience as a distinct field. Brain imaging and recording technologies, along with well-defined behavioral tasks—the essential methodological tools of cognitive neuroscience—are now being used to study development. Technological advances have yielded methods that can be safely used to study structure-function relations and their development in children's brains. These new techniques combined with more refined cognitive models account for the progress and heightened activity in developmental cognitive neuroscience research. The Handbook covers basic aspects of neural development, sensory and sensorimotor systems, language, cognition, emotion, and the implications of lifelong neural plasticity for brain and behavioral development. The second edition reflects the dramatic expansion of the field in the seven years since the publication of the first edition. This new Handbook has grown from forty-one chapters to fifty-four, all original to this edition. It places greater emphasis on affective and social neuroscience—an offshoot of cognitive neuroscience that is now influencing the developmental literature. The second edition also places a greater emphasis on clinical disorders, primarily because such research is inherently translational in nature. Finally, the book's new discussions of recent breakthroughs in imaging genomics include one entire chapter devoted to the subject. The intersection of brain, behavior, and genetics represents an exciting new area of inquiry, and the second edition of this essential reference work will be a valuable resource for researchers interested in the development of brain-behavior relations in the context of both typical and atypical development.

Available in PDF, EPUB and Kindle. Book excerpt: The aim of this publication is to demonstrate the effect of the neural networks on cognitive functions and behavioural patterns during the development phase of a child. Taking as a basis the previous publication in this series dedicated to brain lesion localisation and development, this time it is by examining in particular the frontal lobe, limbic system (hippocampus and amygdala) and visuo-cognitive system that this book looks at the close links between the neural networks and the future development of visual, cognitive and functional capacities. The section on the frontal lobe concentrates on anatomy, mirror neurons, memory, executive functions, the neuropsychology of frontal lobe epilepsy and the resolution of social problems which can occur as a result of brain damage. The part on the limbic system looks at neuro-anatomical organisation and the core functions of the hippocampus and amygdala, problems of language, music, emotions or autism. Finally, the section dedicated to the visuo-cognitive system summarises the visual field problems associated with focal lesions, the correlation with neuro-imagery and visual impairment in children born prematurely.

Book excerpt: The essential reference for human development theory, updated and reconceptualized The Handbook of Child Psychology and Developmental Science, a four-volume reference, is the field-defining work to which all others are compared. First published in 1946, and now in its Seventh Edition, the Handbook has long been considered the definitive guide to the field of developmental science. Volume 2: Cognitive Processes describes cognitive development as a relational phenomenon that can be studied only as part of a larger whole of the person and context relational system that sustains it. In this volume, specific domains of cognitive development are contextualized with respect to biological processes and sociocultural contexts. Furthermore, key themes and issues (e.g., the importance of symbolic systems and social understanding) are threaded across multiple chapters, although every each chapter is focused on a different domain within cognitive development. Thus, both within and across chapters, the complexity and interconnectivity of cognitive development are well illuminated. Learn about the inextricable intertwining of perceptual development, motor development, emotional development, and brain development Understand the complexity of cognitive development without misleading simplification, reducing cognitive development to its biological substrates, or viewing it as a passive socialization process Discover how each portion of the developmental process contributes to subsequent cognitive development Examine the multiple processes – such as categorizing, reasoning, thinking, decision making and judgment – that comprise cognition The scholarship within this volume and, as well, across the four volumes of this edition, illustrate that developmental science is in the midst of a very exciting period. There is a paradigm shift that involves increasingly greater understanding of how to describe, explain, and optimize the course of human life for diverse individuals living within diverse contexts. This Handbook is the definitive reference for educators, policy-makers, researchers, students, and practitioners in human development, psychology, sociology, anthropology, and neuroscience.

Book excerpt: The Cambridge Handbook of Applied Perception Research covers core areas of research in perception with an emphasis on its application to real-world environments. Topics include multisensory processing of information, time perception, sustained attention, and signal detection, as well as pedagogical issues surrounding the training of applied perception researchers. In addition to familiar topics, such as perceptual learning, the Handbook focuses on emerging areas of importance, such as human-robot coordination, haptic interfaces, and issues facing societies in the twenty-first century (such as terrorism and threat detection, medical errors, and the broader implications of automation). Organized into sections representing major areas of theoretical and practical importance for the application of perception psychology to human performance and the design and operation of human-technology interdependence, it also addresses the challenges to basic research, including the problem of quantifying information, defining cognitive resources, and theoretical advances in the nature of attention and perceptual processes.

Available in PDF, EPUB and Kindle. Book excerpt: It is impossible to perceive the innumerable stimuli impinging on our senses, all at once. Out of the myriad stimuli, external and internal, a few are selected for further processing; and even among these, we try to put each in some sort of relation with the others, to be able to make some sense about them all. Time, of course, is an elementary dimension we use to organize our experiences. Thus, the perception of sequences is basic to human cognition. Nevertheless, research addressing sequences is rather sparse. Partly, this is due to difficulty in designing experiments in this area due to huge individual differences. Then, there is the assumption that temporal order has more to do with memory than perception. Another problem is that sequences seem endemic to the auditory world. So much so that some researchers have suggested that sound provides the ‘auditory scaffolding’ for sequencing behavior. Little wonder that research studies addressing sequences in modalities other than audition are extremely rare. This research topic aimed to gather a holistic picture of sequencing behaviour among humans by collecting snapshots of the current research on the topic of sequencing. We particularly sought contributions which addressed sequences beyond the auditory modality. The single unifying criteria for these diverse contributions was that they shed new light on previously unexplored empirical relationships and/or provoked new lines of research with incisive ideas regarding sequencing behavior. Seasoned researchers contributed their views on perception, memory, and production of sequences.
