Effects of Handling on the Physical and Behavioral Development of Siamese Kittens

Abstract

In the recent rash of studies on early experience have been those dealing with increased somesthetic stimulation under the guise of or petting. These studies, usually with rats, have shown remarkable changes in growth, emotionality, learning, and resistance to stress (Bernstein, 1957; Bovard, 1958). The present report deals with the changes in physical characteristics, in emotionality, and in learning in Siamese kittens following handling throughout the first three months after birth. W e expected the handled kittens to show: (a ) more rapid growth as indicated by weight gains; ( b ) lower emotionality; and (c ) superior discrimination performance as compared with that of their controls.
