Elementary Signal Detection Theory Thomas D. Wickens (Professor of Psychology, Professor of Psychology, University of California, Los Angeles)

Elementary Signal Detection Theory By Thomas D. Wickens (Professor of Psychology, Professor of Psychology, University of California, Los Angeles)

Summary

How do humans discrimate ? And is it measurable ? In this book Thomas Wickens explains signal detection theory, which in essence, was divised to provide an explanation for the human ability to discriminate and how might we implement reliable measures to quantify this ability.

Elementary Signal Detection Theory Summary

Elementary Signal Detection Theory by Thomas D. Wickens (Professor of Psychology, Professor of Psychology, University of California, Los Angeles)

Signal detection theory, as developed in electrical engineering and based on statistical decision theory, was first applied to human sensory discrimination about 40 years ago. The theory's intent was to explain how humans discriminate and how we might use reliable measures to quantify this ability. An interesting finding of this work is that decisions are involved even in the simplest of discrimination tasks-say, determining whether or not a sound has been heard (a yes-no decision). Detection theory has been applied to a host of varied problems (for example, measuring the accuracy of diagnostic systems, survey research, reliability of lie detection tests) and extends far beyond the detection of signals. This book is a primer on signal detection theory, useful for both undergraduates and graduate students.

Elementary Signal Detection Theory Reviews

This book contains the theoretical explications of the ways observers detect weak, uncertain, or ambiguous signals. It explains the math underlying the theory, and outlines its uses in measuring an observer's sensitivity. The book is intended to serve as an introductory text for undergraduate or graduate courses in sensation and perception, psychophysics, cognition, and quantitative methods; it may also be used as a reference for researchers. Wickens teaches at the University of California, Los Angeles.--SciTech Book News This book contains the theoretical explications of the ways observers detect weak, uncertain, or ambiguous signals.
