The term just noticeable difference (JND) refers to the amount of change in stimulus intensity necessary to detect a reliable change in sensation. For example, when a stimulus above the absolute threshold is applied to a sense organ, the intensity of the stimulus must be increased by a critical amount (i.e., the JND) before a person is able to report change in sensation.
