D) sensorimotor threshold
E) supraliminal threshold

Question

Quizplus · Accepted Answer

The smallest change in physical energy between two stimuli that is recognized as different is referred to as the difference threshold, also known as the just noticeable difference (JND). This is different from the absolute threshold, which refers to the minimum amount of energy needed for a stimulus to be detected at least 50% of the time, and signal detection, which involves measuring an individual's ability to distinguish between a signal and noise in a given environment. Sensorimotor threshold and supraliminal threshold are not relevant concepts in this context.
