A)Weber's law
B)Weber's fraction
C)Fechner's law

Question

Quizplus · Accepted Answer

Weber's law specifically deals with the concept of JND (just noticeable difference) and explains that the magnitude of the JND is proportional to the intensity of the stimulus. This relationship is known as Weber's fraction, which is a constant percentage of the intensity of the standard stimulus. Therefore, as the intensity of the standard stimulus increases, the JND also increases, in accordance with Weber's law. Fechner's law, on the other hand, deals with the relationship between the physical intensity of a stimulus and the perceived intensity or magnitude of the resulting sensation.
