What is Weber s Law psychology

In fechner's formulation jnds provide the basic unit of perceived intensity.Fechner's law states that the strength of the sensation becomes greater as the logarithm of stimulus intensity increases.The size of the difference threshold, a constant ratio of the standard stimulus, is referred to as the weber's fraction.According to weber's law, this difference threshold is a constant proportion of the original threshold size., also weber's law equation can be written as, ψ = k logs.Cold spring harbor symposia on quantitative biology 30:

The ratio of the magnitude of a stimulant to the quantity which importance must be altered in effort for the modification to be interpreted is a constant.A mathematical model of the difference threshold stating that the magnitude needed to detect physical change in a stimulus is proportional to the absolute magnitude of that stimulus.The law postulating that the strength and intensity required to identify modifications within a stimulant is correlated to the absolute magnitude of the stimulant.Then you asked the observer to increase the intensity of one of the spots.Weber's main interests were the sense of touch and kinesthesis.
