Book excerpt: Originally published in 1974, this volume presents seven detailed views of human information processing at the time. While no single volume can do justice to the breadth of the area, it was hoped that the present selections reflected both the content and methodological approaches currently used by experimental psychologists concerned with the issues and problems of human information processing. The organization of the book is simple, proceeding from the human performance end of the continuum, an overview of which is given in the first chapter. Successive chapters are progressively more concerned with human cognition, and the last chapter gives an overview of human cognition. The intervening chapters are devoted to more specific topics and yield a detailed portrait of the models, findings, and methodology of human information processing.
