Human faces present complex visual patterns that mediate a rich variety of social activity including recognition, emotion, and intention. In recent years considerable progress has been made in understanding how these complex images are interpreted by the brain, and in the development of computer systems for the processing, transmission, and graphical display of faces. This volume provides state-of-the-art reviews of the processes involved in perceiving and recognizing faces, with perspectives from neurophysiology, neuropsychology, cognitive psychology, and developmental psychology. It also includes contributions from engineering and computer science where the techniques of visualization offer some of the richest avenues for future progress. The authors are internationally recognized experts drawn from these various disciplines, and they review their own recent contributions to the field. Much of the current impetus and excitement comes from the remarkable degree of communication and collaboration, often spanning traditional disciplinary boundaries, that characterizes this field of research which is well illustrated by the chapters assembled in this volume.

Fascinated by mechanical gadgetry and technology, Lincoln introduced breechloaders and machine guns into warfare and promoted the use of incendiary weapons, ironclad warships, breechloading cannons, and aerial reconnaissance. Robert Bruce chronicles the President's struggle against bureaucratic red tape and his dealings with the colorful parade of inventors, ordinance experts, bureaucrats, military officers, and lobbyists who heralded a new era in warfare. "It is hardly going too far to say that Lincoln the president cannot be properly understood without some acquaintanceship with this aspect of his character. And it is not going in the least too far to add that Bruce has assembled his material with care, industry, and intelligence and has written a book of deep and surpassing interest and appeal." -- Civil War Book Club Review

This is not simply the story of a year from our past but a dramatic account of a social and political uprising that became a crisis in the course of American development. By 1877 the United States had ground through four years of depression with no end in sight. The mood of the nation was explosive. As labor sought to unite against the great corporations, violence and lawlessness spread through the cities, accented by race riots, lynchings, government corruption, scandal in high places, and the shocking growth of teenage gangs. The summer of 1877 produced a climax: a nationwide railroad strike accompanied by rioting coast to coast. Mr. Bruce’s moving account of these events portrays a nation trying to cope with an industrial depression before it had learned about the problems of industrialism. The upheaval was perhaps our closest brush with class revolution in America. “A taut narrative that is relieved by flashes of an appropriately sardonic humor. Mr. Bruce has resisted the temptation to let his spectacular story turn into a mere hour-by-hour re-creation of mayhem and emotion. All along the way he thoughtfully assesses just what this year meant in American history.�—Eric F. Goldman, New York Times. “The author goes to the sources in scholarly fashion but reports it in a popular style…An informative and readable book.�—C. Vann Woodward.
