The smallest difference in the magnitude of two stimuli that an observer can reliably detect is called the:
A)absolute threshold for the stimulus
B)perceptual threshold for the stimulus
C)adaptation threshold for the stimulus
D)difference threshold for the stimulus

The difference threshold, also called the just noticeable difference (JND), is the smallest difference in stimuli that an observer can reliably detect. It is the threshold at which a change in a stimulus becomes noticeable to an individual. The other options (A, B, and C) refer to different types of thresholds but not specifically to the smallest difference in stimuli that can be detected.
