Signal Detection Theory: What It Is & Why It Matters | Keiser Graduate
Signal detection theory involves the measurement of the difference between two distinct patterns. The first is called the “stimulus” when you're talking about ...
Figure 4 shows two sets of probability of occurrence curves. When the signal is stronger there is more separation between the two probability of occurrence ...
According to the theory, there are a number of determiners of how a detecting system will detect a signal, and where its threshold levels will be. The theory ...
Signal detection theory - part 1 (video) - Khan Academy
It originated in radar technology and now applies to psychology. The theory investigates how strong a signal must be for detection. It considers ...
Signal Detection Theory - an overview | ScienceDirect Topics
SDT is a theoretical form of discrimination between signal (stimulus) and noise. Noise signals can be considered distractors, and responses are classified into ...
“UTILIZING” SIGNAL DETECTION THEORY - PMC
Mathematical modeling shows that a perceiver's sensitivity and bias should be inversely related. A “line of optimal response” (LOR; dashed line) is defined by ...
Signal Detection Theory | Definition & Examples - Lesson - Study.com
Signal detection theory is about detecting stimuli (a signal) through the senses. Testing the signal detection theory exposes observers to signals.
Signal Detection Theory - an overview | ScienceDirect Topics
The signal detection theory assumes that the subjects estimate the probabilities that a test item came from the distributions for target and distractor items, ...
The forgotten history of signal detection theory. - APA PsycNet
Here, I trace the origins of signal detection theory, beginning with Fechner's (1860/1966) Elements of Psychophysics.

Using Signal Detection Theory to Better Understand Cognitive Fatigue
We show the relevance of SDT measures in the understanding of fatigue, thus providing researchers with a new set of tools with which to better understand the ...
Signal Detection Theory: Introduction
The theory of signal detection theory evolved from the development of communications and radar equipment the first half of this century.

Signal detection theory provides a precise language and graphical notation for analyzing decision making in the presence of uncertainty. Signal detection ...
Calculation of signal detection theory measures
Signal detection theory (SDT) may be applied to any area of psychology in which two different types of stimuli must be discriminated. We describe several o.

The Theory of Signal Detection
When a subject is presented with the signal at any particular time, the signal will fall along the sensory continuum according to the SN distribution. The ...
