Anne Treisman has been one of the most influential cognitive psychologists in the last fifty years. She is best known for her work on attention, and she has been especially concerned with the interactions among visual perception, attention, and memory as they relate to conscious and unconscious experience. Her feature integration theory has been one of the organizing ideas in the field for three decades. While still a graduate student at Oxford, she helped launch the modern study of attention. In this book, several of her most influential papers are reprinted (including some of the harder-to-find early work). To accompany these reprints, other experts comment and/or show how their own work has been shaped by Treisman's ideas and findings. The chapters include discussions of auditory and visual attention, the role of features in selection, parallel and serial processing, and automaticity. The roots and evolution of Feature Integration Theory and related models like Guided Search are described, and the chapters explore the interactions of attention and perception at the cognitive, neuropsychological, and biological levels. The chapters consider the critical role of binding in perception, the role of attention in scene perception, as well as the influence of cognitive load, memory, reflection, and perceptual learning on early and late processing. The book shows how methods to study conscious perceptual awareness have evolved over the years.
