Male rats were tested in a bar pressing situation in which the reward was 10 sec. of either visual, partial physical, or full physical contact with another rat. Among rats reared together all Ss learned the response; among rats reared separately learning increased with degree of contact permitted. The sex of the display animal had apparently no influence upon behavior. The importance of the tactile receptors in a social situation is emphasized. From Psyc Abstracts 36:01:1EO64A.
