Available in PDF, EPUB and Kindle. Book excerpt: A visual stimulus may be selectively attended on the basis of its location in space, a specific feature, or as a whole object. While a relatively large amount of research has examined the neural basis of location-based and feature-based attentional selection, few studies have examined the neural correlates of the spread of attention from one feature of an object to another, reflecting the selection of an object as an "integrated feature ensemble" (Schoenfeld et al., 2003; O'Craven, Downing, & Kanwisher, 1999). The research in this dissertation examined the electrophysiological correlates of the spread of selective attention to a task-irrelevant color feature of an object using the event-related potential (ERP) brain imaging technique. The temporal dynamics of this spread of attention were examined for two classes of objects, grouped-arrays of lines (Study 1) and geometric shapes (Study 2). In each study, overlapping objects were presented and the participants' task was to sustain attention to one object versus another to judge a change in the thickness of one of the lines of the grid (Study 1) or a change in object shape (Study 2). On some trials, either the attended object or the unattended object was colored, and color was irrelevant to the task. Difference ERPs indicated that color was first encoded in the visual cortex by 100 ms. However, the effect of attention on the task-irrelevant color feature was evident in later ERP modulations. A bilateral parietal/occipital positivity beginning at 200 ms (Study 2) and a midline occipital negativity beginning at 280 ms (Studies 1 & 2) were associated with the selection of the irrelevant color of the attended object. Source localization analyses suggested that the neural generators of the attention-related facilitation of the irrelevant color feature were situated in ventral occipital cortical regions near color-selective cortical areas. These data provide further evidence for the "integrated competition" model (Duncan, 1996; 1997), which posits that the neural basis for the perceptual integration of an attended object consists of enhanced activity in the network of specialized modules that encode its individual features, including those that are not relevant to the immediate task.

Available in PDF, EPUB and Kindle. Book excerpt: Cognitive Electrophysiology of Attention explores the fundamental mechanisms of attention and related cognitive functions from cognitive neuroscience perspectives. Attention is an essential cognitive ability that enables humans to process and act upon relevant information while ignoring distracting information, and the capacity to focus attention is at the core of mental functioning. Understanding the neural bases of human attention remains a key challenge for neuroscientists and psychologists, and is essential for translational efforts to treat attentional deficits in a variety of neurological and psychiatric disorders. Cognitive electrophysiology is at the center of a multidisciplinary approach that involves the efforts of psychologists, neuroscientists, neuropsychologists, psychiatrists, and neurologists to identify basic brain mechanisms and develop translational approaches to improve mental health. This edited volume is authored by leading investigators in the field and discusses methods focused on electrophysiological recordings in humans, including electroencephalography (EEG) and event-related potential (ERP) methods, and also incorporates evidence from functional magnetic resonance imaging (fMRI). Cognitive Electrophysiology of Attention illuminates specific models about attentional mechanisms in vision, audition, multisensory integration, memory, and semantic processing in humans. Provides an exhaustive overview of attention processes, going from normal functioning to the pathological, and using a combination of methodological tools An important reference for electrophysiology researchers looking at underlying attention processes rather than the methods themselves Enables researchers across a broad range of cognitive-process and methodological specialties to stay current on particular hypotheses, findings, and methods Edited and authored by the worldwide leaders in the field, affording the broadest, most expert coverage available

Available in PDF, EPUB and Kindle. Book excerpt: During the last three decades, there have been enormous advances in our understanding of the neural mechanisms of selective attention at the network as well as the cellular level. The Oxford Handbook of Attention brings together the different research areas that constitute contemporary attention research into one comprehensive and authoritative volume. In 40 chapters, it covers the most important aspects of attention research from the areas of cognitive psychology, neuropsychology, human and animal neuroscience, computational modelling, and philosophy. The book is divided into 4 main sections. Following an introduction from Michael Posner, the books starts by looking at theoretical models of attention. The next two sections are dedicated to spatial attention and non-spatial attention respectively. Within section 4, the authors consider the interactions between attention and other psychological domains. The last two sections focus on attention-related disorders, and finally, on computational models of attention. Aimed at both scholars and students, the Oxford Handbook of Attention provides a concise and state-of-the-art review of the current literature in this field.

Book excerpt: Originally published in 1981, perceptual organization had been synonymous with Gestalt psychology, and Gestalt psychology had fallen into disrepute. In the heyday of Behaviorism, the few cognitive psychologists of the time pursued Gestalt phenomena. But in 1981, Cognitive Psychology was married to Information Processing. (Some would say that it was a marriage of convenience.) After the wedding, Cognitive Psychology had come to look like a theoretically wrinkled Behaviorism; very few of the mainstream topics of Cognitive Psychology made explicit contact with Gestalt phenomena. In the background, Cognition's first love – Gestalt – was pining to regain favor. The cognitive psychologists' desire for a phenomenological and intellectual interaction with Gestalt psychology did not manifest itself in their publications, but it did surface often enough at the Psychonomic Society meeting in 1976 for them to remark upon it in one of their conversations. This book, then, is the product of the editors’ curiosity about the status of ideas at the time, first proposed by Gestalt psychologists. For two days in November 1977, they held an exhilarating symposium that was attended by some 20 people, not all of whom are represented in this volume. At the end of our symposium it was agreed that they would try, in contributions to this volume, to convey the speculative and metatheoretical ground of their research in addition to the solid data and carefully wrought theories that are the figure of their research.
