In De Tactu, published in English as On touch: anatomical and physiological notes [9], Weber proposed there was a threshold of sensation in each individual. His studies on sensation and touch, along with his emphasis on good experimental techniques gave way to new directions and areas of study for future psychologists, physiologists, and anatomists.
