WebApr 8, 2024 · Weber-Fechner Law. The Weber-Fechner law is a mathematical model that describes the relationship between stimulus intensity and difference threshold. According to this law, the difference threshold is proportional to the magnitude of the initial stimulus. This means that it's easier to detect a difference in a larger stimulus than in a smaller one. WebFechner's law says mind (conscious experience) and matter (stimulus intensity) are the same thing as well. This was a BIG DEAL. If you can measure sensation then you can do science on the mind, on conscious experience. WOW!. But first we need some basic concepts. Psychophysical Problems Introduced. Detection Problem
