PSYC 230 UIUC EXAM 1 QUESTIONS AND CORRECT ANSWERS Signal Dectection Theory a theory predicting how and when we detect the presence of a faint stimulus (signal) amid background stimulation (noise). Assume that there is no single absolute threshold and that detection depends partly on a person's experience, expectations, motivation, and alertness criterion controlled by the observer d prime The distance between the signal and the external noise + signal. Large d' - increasing the...
