The World of Touch

For the first time, David Katz's classic monograph The World of Touch has been translated into English. Regarded as one of the premiere experimental psychologists, Katz vigorously opposed the atomism and "tachistoscopic" mentality typical of the sensory psychology of his day. In The World of Touch, Katz sought to dispel the invidious distinction between the supposedly higher (e.g., vision, audition) and lower (e.g., touch) senses. To help touch regain its original prominence in the field, Katz demonstrated, through very simple, yet creative experiments, how fascinating the abilities of touch are, and how valuable the tactual stimulus can be in specifying objects, surfaces, substances, and events. In addition, Katz emphasized the importance of higher-order invariants in the perception of objects, and the holistic quality of perception in time as well as space.
