Weber's Law says that low intensity stimuli need greater changes to detect a difference.

Question

Quizplus · Accepted Answer

Weber's Law actually states that the size of the just noticeable difference (i.e., the smallest change in stimulus intensity that can be detected) is a constant proportion of the original stimulus intensity. This means that for higher intensity stimuli, greater changes are needed to detect a difference, not for low intensity stimuli.
