Weber-Fechner Law

Description:

The Weber-Fechner Law, also known as the Weber's Law, is a principle in psychology that describes the relationship between the physical intensity of a stimulus and the perceived intensity or magnitude of a sensation. The law quantifies the concept of just noticeable difference (JND), which means that the change in stimulus intensity required for an individual to detect a difference in sensation is not constant but rather proportional to the initial intensity of the stimulus.

Sample Sentences:

Sense 1 - Psychology:

In psychology, the Weber-Fechner Law is used to understand how our perception of stimuli changes as their intensity increases or decreases.

The Weber-Fechner Law states that if you increase the intensity of a stimulus, the perceived difference in sensation will also increase.

Sense 2 - Biology:

The Weber-Fechner Law is also applied in biology to study the relationship between the intensity of a physical stimulus, such as light or sound, and the physiological response it elicits.

According to the Weber-Fechner Law, if you double the intensity of a sound wave, the increase in perceived loudness will not be linear but rather logarithmic.
