Auditory Signal Detection (One-Day Experiment) Laboratory Module by Douglas R. Elrod, Cornell University Introduction. What is now known as Signal Detection Theory (SDT) got its start in radar research in the mid 1950's. Soon other fields, particularly psychology, had adopted its methods.Signal Detection Theory explores decision-making under uncertainty. It originated in radar technology and now applies to psychology. The theory investigates how strong a signal must be for detection. It considers two variables: D Prime (signal strength) and C (strategy).

In perceptual, cognitive, and diagnostic tasks, accuracy depends on both limited sensitivity and the application of a decision process. By making explicit assumptions about the nature of the cognitive representation, signal detection theory (SDT) measures the contributions of these two components of performance.
