Fechner's law
Fechner's law, also known as the Weber-Fechner law, is a fundamental principle in psychophysics that describes the relationship between the physical intensity of a stimulus and the perceived intensity of that stimulus. It states that the perceived intensity of a stimulus is proportional to the logarithm of the physical intensity of the stimulus.
- Sensory discrimination
Fechner's law has important implications for sensory discrimination, which is the ability to detect differences between stimuli. According to Fechner's law, the just noticeable difference (JND) between two stimuli is a constant proportion of the original stimulus intensity. This means that the JND will be larger for more intense stimuli and smaller for less intense stimuli.
- Signal detection theory
Fechner's law has also been used to develop models of signal detection theory, which is a mathematical framework for understanding how individuals make decisions in the presence of noise. Signal detection theory incorporates Fechner's law to predict the probability that an individual will correctly detect a signal in the presence of noise.

Fechner's law has had a significant impact on William Garner's work on sensory discrimination and perception. Garner developed the Garner discrimination function, which is a mathematical model that predicts the probability that an individual will correctly discriminate between two stimuli. The Garner discrimination function is based on Fechner's law and has been used to study a wide range of sensory discrimination tasks.
Fechner's law is a fundamental principle in psychophysics that has important implications for our understanding of sensory discrimination and perception. William Garner's work on sensory discrimination and perception has been deeply influenced by Fechner's law, and his research has helped to extend and refine our understanding of this important principle.
