"Révész's work encompassed varied fields. His early interest centered on visual perception, and later he concerned himself with the psychological aspects of music. He carried out tests on the sense of touch, and identified those elements of tactile perception that are not shared by the optic and acoustic senses. This research brought him in contact with blind persons, and Revesz, in part moved by sympathy, conducted studies on the personal life of the blind. He also devoted himself to understanding the basic differences between humans and animals, in which connection he produced his study on the origins of languages."
