At what point can we detect a signal. Origins in sonar - is signal a small fish vs. large whale. Its role in psychology - Imagine being given a list. Correct answer: diffusion of responsibility. Explanation: Members of a group will often feel less inclined to do something about a situation; the larger the group, the less an individual will feel a sense of responsibility to take charge. This is called a "diffusion of responsibility" and is thought to be responsible for the "bystander effect ... The Signal Detection Theory provides us with a framework to understand the Decision-making process in situations involving uncertainty. Detection of stimuli can depend upon the strength of the subject's senses, and the criterion on the signal's strength decided by the subject for detection.contains introductions to probability theory, statistical decision theory, waveform analysis, and experimental techniques. it reviews the basic experiments that support the application of detection theory in psychophysics, and describes experimental applications of the theory to a variety of substantive problems in psychology. it considers the complexities and …Signal detection theory. This theory argues that the number of alerts decreases during a continuous performance task. In other words, if your sustained attention is worn thin, the stimulus would have to be more salient for you to detect it. Thus, you might find that when you pay attention for a long period of time, your correct answers decrease.Signal detection theory provides a precise language and graphic notation for analyzing decision making in the presence of uncertainty.

Overview of SDT. SDT’s power as an analytic tool comes from separating a perceiver’s behavior into two underlying components, sensitivity and bias (see Précis of Signal Detection Theory in Supplemental Material available online).
