Quizplus · Accepted Answer

Weber's law states that a just noticeable difference (JND) between two stimuli is proportional to the magnitude of the initial stimulus. Specifically, the JND is a constant proportion of the intensity of the initial stimulus. This means that as the intensity of the initial stimulus increases, the JND also increases proportionally. Therefore, the correct answer is B.
