B) functional encoding.
C) saturation.
D) jnd.

Question

Quizplus · Accepted Answer

The smallest difference in stimulation that can be reliably detected by an observer when two stimuli are compared is called the "just noticeable difference" (JND), also known as the difference threshold. This is the minimum amount of change needed for a person to detect a difference between two stimuli. Therefore, choice D, jnd, is the correct answer. Choices A, B, and C are unrelated concepts to the JND.
