Attention, predictions and expectations, and their violation: attentional control in the human brain
In the burdened scenes of everyday life, our brains must select from among many competing inputs for perceptual synthesis - so that only the most relevant receive full attention and irrelevant (distracting) information is suppressed. At the same time, we must remain responsive to salient events outside our current focus of attention - and balancing these two processing modes is a fundamental task our brain constantly needs to solve. Both the physical saliency of a stimulus, as well as top-down predictions about imminent sensations crucially influence attentional selection and consequently the response to unexpected events. Research over recent decades has identified two separate brain networ...
Theories of Visual Attention - linking cognition, neuropsychology, and neurophysiology
The Neural Theory of Visual Attention of Bundesen, Habekost, and Kyllingsbæk (2005) was proposed as a neural interpretation of Bundesen’s (1990) theory of visual attention (TVA). In NTVA, visual attention functions via two mechanisms: by dynamic remapping of receptive fields of cortical cells such that more cells are devoted to behaviorally important objects than to less important ones (filtering) and by multiplicative scaling of the level of activation in cells coding for particular features (pigeonholing). NTVA accounts for a wide range of known attentional effects in human performance and a wide range of effects observed in firing rates of single cells in the primate visual system and thus provides a mathematical framework to unify the 2 fields of research. In this Research Topic of Frontiers in Psychology, some of the leading theories of visual attention at both the cognitive, neuropsychological, and neurophysiological levels are presented and evaluated. In addition, the Research Topic encompasses application of the framework of NTVA to various patient populations and to neuroimaging as well as genetic and psychopharmacological studies.
The enigma of Bálint's syndrome: complexity of neural substrates and cognitive deficits
Bálint’s syndrome is named after the Hungarian physician who first reported a remarkable case of a man with complex visuospatial deficits following bilateral lesions within parietal and occipital cortex (Bálint, 1909). The syndrome has three primary symptoms: simultanagnosia (impaired spatial awareness of more than one object at time), optic ataxia (misreaching to visual targets) and ocular apraxia (described by Bálint as “psychic paralysis of gaze”). Balint’s patients not only cannot perceive more than one object at time and therefore show poor comprehension of multi-object visual scenes i.e. poor detection of all the objects present and difficulty in grasping the relationship be...
The Oxford Handbook of Perceptual Organization
Perceptual organization comprises a wide range of processes such as perceptual grouping, figure-ground organization, filling-in, completion and perceptual switching. 'Oxford Handbook of Perceptual Organization' provides a broad and extensive review of the current literature, written in an accessible form for scholars and students.
The Cognitive Neuroscience of Attention
Attention refers to our ability to selectively process the vast array of stimuli impinging upon our senses at every moment. The mental processes of attention are critical for allowing us to maintain focus and complete tasks efficiently, even within distracting environments. The brain mechanisms of attention have been studied for decades, yet much still remains unknown, and consensus on core issues remains elusive. A unique aspect of this book are chapters that highlight recent debates on critical issues in attention research. Each of these chapters includes a comprehensive discussion paper that is followed by peer commentaries and an authors' responses. These debates include whether attentio...
fMRI Neurofeedback
fMRI Neurofeedback provides a perspective on how the field of functional magnetic resonance imaging (fMRI) neurofeedback has evolved, an introduction to state-of-the-art methods used for fMRI neurofeedback, a review of published neuroscientific and clinical applications, and a discussion of relevant ethical considerations. It gives a view of the ongoing research challenges throughout and provides guidance for researchers new to the field on the practical implementation and design of fMRI neurofeedback protocols. This book is designed to be accessible to all scientists and clinicians interested in conducting fMRI neurofeedback research, addressing the variety of different knowledge gaps that ...
Essence of Memory
This selection of reviews gives an up-to-date picture of memory research. Great progress has been made in identifying the memory trace at the molecular and cellular level and individual reviews address the major mechanisms by which changes in synaptic strength can persist. Exciting research at the systems level is also reviewed including the growing importance of changes in inhibitory interneurons and how they play a role in memory formation. Finally, reviews present cognitive and neurobiological models of human memory that explain, characterize and organize the act of memory within a coherent framework. - Provides an unique overview that covers all perspectives and methodological approaches to memory - Broad coverage of memory research from molecular to human studies in one source - Up-to-date reviews give the latest important ideas on memory formation
Gilbert and Gubar's The Madwoman in the Attic after Thirty Years
When it was published in 1979, Sandra M. Gilbert and Susan Gubar's The Madwoman in the Attic: The Woman Writer and the Nineteenth-Century Literary Imaginationwas hailed as a pathbreaking work of criticism, changing the way future scholars would read Jane Austen, Mary Shelley, the Brontës, George Eliot, and Emily Dickinson. This thirtieth-anniversary collection adds both valuable reassessments and new readings and analyses inspired by Gilbert and Gubar’s approach. It includes work by established and up-and-coming scholars, as well as retrospective accounts of the ways in which The Madwoman in the Attic has influenced teaching, feminist activism, and the lives of women in academia. These co...
Grasp
'Sarma's book may be the most important work on education written this century' - Skeptic As the head of Open Learning at MIT, Sanjay Sarma has a daunting job description: to fling open the doors of the MIT experience for the benefit of the wider world. But if you're going to undertake such an ambitious project, you must first ask: How exactly does learning work? What conditions are most conducive? Are our traditional classroom methods - lecture, homework, test, repeat - actually effective? And if not, which techniques are? Grasp takes readers across multiple frontiers, from fundamental neuroscience to cognitive psychology and beyond, as it explores the future of learning. For instance: · S...
Developmental Neuropsychology
A thorough revision of Human Developmental Neuropsychology, this book is the most detailed and complete overview of child neuropsychology available today. It begins with a brief introduction to the nervous system, including an up-to-date review of theories of lateralization and sex differences. The second part presents a discussion of newborn and infant assessment, critical periods, disconnection syndromes and other relevant issues in developmental neuropsychology. The next section deals with disorders of development, such as anoxia, malnutrition and head trauma, in detail. The final part offers a comprehensive discussion of functional disturbances, including neurological soft signs, attentional disorders, language disorders, and emotional and behavioral disorders. New to this edition are a chapter on newborn and infant assessment and a chapter on cognitive development in relation to brain functions. The text also includes new information on attentional syndromes, infant HIV infection and Tourette's syndrome, among many other topics.
