Synopsis :

This volume presents the fundamentals of signal detection theory (SDT), a theory which has been used to great advantage in the study of sensory processes, recognition thresholds, vigilance, memory, perception, reaction-times, as well as in many areas outside psychology. The text begins with a clear exposition of the elements of decision theory, then proceeds to a detailed examination of receiver-operating characteristics (ROCs), giving particular attention to ROCs based on probability laws (e.g., the normal, binomial, chi-square, Poisson, and gamma distributions, important in many areas of science). The author provides an extensive treatment of the ROCs that arise from the Poisson random process, and introduces a consistent terminology for ROC analysis. Special features of the book include: -- numerous worked examples to illustrate all the essential points; -- eight detailed appendices, including an outline of the technique of transforming the probability distributions encountered in SDT, and an explanation of the relationship between the chi-square and the Poisson distributions. This comprehensive work will be of immense value to professionals and graduate students in experimental psychology, psychophysics, and psychoacoustics. It also has wide application to such diverse areas as information retrieval, medical diagnosis, and library science.
