Question

Quizplus · Accepted Answer

The mathematical measure of sensitivity in signal-detection theory is known as "d-prime" or "d'". It is used to calculate the ability of the perceptual system to differentiate between a signal and background noise, with higher values indicating greater sensitivity. Other options listed may be used in signal-detection theory, but they do not directly measure sensitivity.
