Edited by John A. Swets in 1964, this book was the first to bring together into one volume a broad coverage of modern signal detection theory applications to human performance, specifically in auditory and visual sensory tasks. Applications in the book address several substantive problems in psychology including the integration of sensory information, signal uncertainty, auditory frequency analysis, speech communication, vigilance and recognition memory. Signal Detection and Recognition outlines how decision factors are centrally involved in even simplest detection task and how sensory capacity can be assessed independently. This edition includes a new topical bibliography of more than 1000 citations. This book is a must for psychologists and engineers working in the field of communications and man-machine systems.
