C)depend on the energy necessary to stimulate a sensory receptor.
D)are measured in Judgmental Normal Differences.

Question

Quizplus · Accepted Answer

Difference thresholds, also known as just noticeable differences, are the smallest detectable difference in the intensity of a stimulus. This means that the threshold occurs when we can perceive a change in the strength or amount of the stimuli, rather than just detecting its presence or absence. Therefore, option B is correct. Option A refers to the absolute threshold, which is the minimal intensity necessary to detect a stimulus. Option C is related to the sensory threshold, which indicates the amount of energy necessary to excite a sense receptor. Option D is not a relevant concept in this context.
