Examples
- The Weber-Fechner law describes how the intensity of a sensation increases as the logarithm of the stimulus intensity, a fundamental principle in the field of psychophysics.
- Researchers have long relied on the Weber-Fechner law to quantify the relationship between stimulus intensity and subjective experience in human perception.
- The Weber-Fechner law provides a mathematical framework for understanding how human perception changes in response to varying levels of sensory stimuli.
- By applying the Weber-Fechner law, psychologists can better grasp the underlying mechanisms of human perception and its limitations.
- Despite being discovered in the 19th century, the Weber-Fechner law remains a cornerstone of psychophysics and continues to influence new research in the field.
