Anatomically, the central nervous system looks remarkably symmetrical--from the relatively simple structures of the spinal cord to the extensively convoluted folds of the cerebral hemispheres. At the functional level, however, there are striking differences between the left and right hemispheres. Although popular writings attribute language abilities to the left hemisphere and spatial abilities to the right, differences in hemispheric function appear to be more subtle. According to Ivry and Robertson, asymmetries over a wide range of perceptual tasks reflect a difference in strength rather than kind, with both hemispheres contributing to the performance of complex tasks, whether linguistic or spatial. After an historical introduction, the authors offer a cognitive neuroscience perspective on hemispheric specialization in perception. They propose that the two hemispheres differ in how they filter task-relevant sensory information. Building on the idea that the hemispheres construct asymmetric representations, the hypothesis provides a novel account of many laterality effects. A notable feature of the authors' work is their attempt to incorporate hemispheric specialization in vision, audition, music, and language within a common framework. In support of their theory, they review studies involving both healthy and neurologically impaired individuals. They also provide a series of simulations to demonstrate the underlying computational principles of their theory. Their work thus describes both the cognitive and neurological architecture of hemispheric asymmetries in perception.

The seventeenth century witnesses the demise of two core doctrines in the theory of perception: naïve realism about color, sound, and other sensible qualities and the empirical theory, drawn from Alhacen and Roger Bacon, which underwrote it. This created a problem for seventeenth century philosophers: how is that we use qualities such as color, feel, and sound to locate objects in the world, even though these qualities are not real? Ejecting such sensible qualities from the mind-independent world at once makes for a cleaner ontology, since bodies can now be understood in purely geometrical terms, and spawns a variety of fascinating complications for the philosophy of perception. If sensible qualities are not part of the mind-independent world, just what are they, and what role, if any, do they play in our cognitive economy? We seemingly have to use color to visually experience objects. Do we do so by inferring size, shape, and motion from color? Or is it a purely automatic operation, accomplished by divine decree? This volume traces the debate over perceptual experience in early modern France, covering such figures as Antoine Arnauld, Robert Desgabets, and Pierre-Sylvain Régis alongside their better-known countrymen René Descartes and Nicolas Malebranche.

The brain ... There is no other part of the human anatomy that is so intriguing. How does it develop and function and why does it sometimes, tragically, degenerate? The answers are complex. In Discovering the Brain, science writer Sandra Ackerman cuts through the complexity to bring this vital topic to the public. The 1990s were declared the "Decade of the Brain" by former President Bush, and the neuroscience community responded with a host of new investigations and conferences. Discovering the Brain is based on the Institute of Medicine conference, Decade of the Brain: Frontiers in Neuroscience and Brain Research. Discovering the Brain is a "field guide" to the brainâ€"an easy-to-read discussion of the brain's physical structure and where functions such as language and music appreciation lie. Ackerman examines: How electrical and chemical signals are conveyed in the brain. The mechanisms by which we see, hear, think, and pay attentionâ€"and how a "gut feeling" actually originates in the brain. Learning and memory retention, including parallels to computer memory and what they might tell us about our own mental capacity. Development of the brain throughout the life span, with a look at the aging brain. Ackerman provides an enlightening chapter on the connection between the brain's physical condition and various mental disorders and notes what progress can realistically be made toward the prevention and treatment of stroke and other ailments. Finally, she explores the potential for major advances during the "Decade of the Brain," with a look at medical imaging techniquesâ€"what various technologies can and cannot tell usâ€"and how the public and private sectors can contribute to continued advances in neuroscience. This highly readable volume will provide the public and policymakersâ€"and many scientists as wellâ€"with a helpful guide to understanding the many discoveries that are sure to be announced throughout the "Decade of the Brain."
Perception and Misperception in International Politics

Since its original publication in 1976, Perception and Misperception in International Politics has become a landmark book in its field, hailed by the New York Times as "the seminal statement of principles underlying political psychology." This new edition includes an extensive preface by the author reflecting on the book's lasting impact and legacy, particularly in the application of cognitive psychology to political decision making, and brings that analysis up to date by discussing the relevant psychological research over the past forty years. Jervis describes the process of perception (for example, how decision makers learn from history) and then explores common forms of misperception (such as overestimating one's influence). He then tests his ideas through a number of important events in international relations from nineteenth- and twentieth-century European history. Perception and Misperception in International Politics is essential for understanding international relations today.

Since the end of the Cold War, one of the most significant debates in international relations has been the question of whether the rise of China as a major economic, political and military power will be a force for stability or instability in the international system and the East Asian region. Forceful arguments have been put forward on both sides. This book examines perceptions of the 'China Threat', and governments' policies in response to the perceived threat in a wide range of countries, including the United States, Russia, Europe, Japan, South Asia, South-East Asia and the Middle East, as well as the perceptions of the Chinese themselves. For each country current security concerns and policies, especially the policy of engagement, are examined in detail, and future prospects for relations with China are assessed. As the Bush administration in Washington increasingly focuses on China as a 'strategic competitor' and Sino-US relations becomes increasingly tense, the 'China Threat' issue has come to dominate the security agenda in the Asia-Pacific region, and now poses the biggest foreign policy challenge of the 21st century.

In this volume, Baz offers a wide-ranging discussion of Wittgenstein’s remarks on aspect-perception, with special focus on Wittgenstein’s method. Baz starts out with an interpretation of Wittgenstein’s remarks on aspects and continues with attempts to characterize and defend Wittgenstein’s approach to the understanding and dissolution of philosophical difficulties. Baz ends with attempts to articulate—under the inspiration of Merleau-Ponty’s phenomenology—certain dissatisfactions, both with Wittgenstein’s remarks on aspect perception, and with his philosophical approach more generally. On the way, Baz explores connections between Wittgenstein’s remarks on aspects and Kant’s aesthetics. He examines ways in which the remarks on aspects may be brought to bear on contemporary philosophical work on perception. He discusses some of the implications of Wittgenstein’s work on aspect perception for issues in moral philosophy and the philosophy of action.
