Question

Quizplus · Accepted Answer

Signal detection is the technique used to determine the ability of someone to detect the presence of a stimulus by presenting a signal (stimulus) embedded in noise (distraction) and measuring the individual's ability to detect the signal. Psychophysics is a broader field that also includes the study of how the signal is perceived (brightness, loudness, etc.), not just its detection. Systematic introspection and functionalism are not methods used to measure stimulus detection.
