1 janv. 1834 - 1834 Weber publishes on the "Sensation of Touch" --------------------------- Weber's Law and "just noticeable differences (JNDs)"

Description:

Weber's Law: K = JND/S

Importance:
(a) Subjects mental events (sensations) to measurement and mathematical formulation. (eventually leads to importance of psychophysics in Wundt's 'new psychology')
(b) Shows that there is not a one-to-one relationship between changes in the physical world and psychological experience of those changes. Understanding how the mind organizes its experiences requires knowing more than just the physical dimensions of a stimuli; also requires an attempt to determine how the mind interprets said stimuli.
(c) Shows that mental and physical events could be related mathematically.
