A)the absolute threshold.
B)the just noticeable difference.

D)the relative threshold.

Question

Quizplus · Accepted Answer

The volume at which Ernie responds five times is called the absolute threshold, which is the minimum stimulation necessary for detection 50% of the time. The just noticeable difference is the smallest difference in stimulation that can be detected 50% of the time, and Weber's law states that the degree of difference between two stimuli required for detection of a difference is proportional to the magnitude of the stimuli. The relative threshold is not a commonly used term in psychology.
