In psychophysics, the smallest detectable change in a stimulus or difference between two stimuli that can be reliably detected, often defined as the difference for which the percentage of correct discriminations is 75 per cent, though other percentages are sometimes used. The just noticeable difference, also known as the difference threshold, is the smallest possible difference between two stimuli that can be detected at least half the time.
