Fechner fraction
WebWeber's Law ( E. H. Weber, in 1834 ) states that the ratio of ΔI/I is constant for a specific measure. Where ΔI = Differential threshold I = Initial stimulus intensity K= Weber fraction Weber’s Law states that the size of the just noticeable difference (jnd) is a constant proportion (K times) of the original stimulus value.

The idea of additive cumulation of sensitivity values lends itself to sweeping generalizations of Fechnerian scaling. Publication types
