WebAlthough, then, psychic measurement depends upon Weber's law only within certain limitations in the domain of outer psycho-physics, it may well get its unconditional support from this law in the field of inner psychophysics.

Web8 jun. 2024 · The Weber -Fechner Principle: An Approximate psychological law relating the degree of response or sensation of a sense organ and the intensity of the stimulus. The law asserts that equal increments of sensation are associated with equal increments of the logarithm of the stimulus, or that the just noticeable difference in any sensation results ...
WebThere have been three main ideas about the basic law of psychophysics. In 1860, Fechner used Weber’s law to infer that the subjective sense of intensity is related to the physical intensity of a stimulus by a logarithmic function (the Weber-Fechner law).

WebTwo common psychophysical laws are Fechner’s Law and Stevens’ Power Law. In this study you will judge how bright several color patches are. According to Fechner’s law, the perceived (psychological) brightness of the color patches should be a logarithmic function of the physical intensity of the color patches: ψ = k ln (I / I 0)
