Ernest Weber

Ernest Weber was a German physiologist best known for his work in sensory perception. He studied how people detect small differences in stimuli, such as weight, light, or sound. Weber discovered that the ability to notice a difference depends on the proportion between the change and the original stimulus, not just the amount itself. This idea is called Weber’s Law, which helps explain how our sensory system perceives changes consistently across different senses. His research laid important groundwork for understanding human perception and the functioning of the nervous system.
