Who is known for conducting the physiological studies associated with the sense of touch?

Ernst Weber is recognized for his pioneering work in the physiological studies related to the sense of touch, particularly through his research on sensory perception. His most notable contribution is the formulation of Weber's Law, which describes the relationship between the magnitude of a stimulus and the just noticeable difference (JND) detectable by the observer. This law explains how the perception of changes in stimuli, such as weight or pressure, follows a proportional rule, which is fundamental in understanding sensory processing.

Weber's focus on tactile stimuli and his rigorous experimental methods laid the groundwork for future research in psychophysics and the exploration of sensory thresholds. His insights helped to quantify how our senses perceive changes in the environment, which is a cornerstone in the study of sensory systems in psychology.
