| Summary |
"In laboratories of psychology it is common practice to rely on the need of animal subjects for food almost to the exclusion of other possible forms of motivation, whereas in the case of human subjects the opposite is true. This difference may be unfavorable to the comparability of results for man versus other animals. For this reason, and also on account of convenience, economy, nutritional hygiene, dietary regimen, and the importance of extending motivation to higher psychological levels than those of common physiological needs, it would seem important to attempt to extend the range of experimental motivation for animal subjects. In the Yale Laboratories of Primate Biology this is being attempted for the chimpanzee by tests of the value, dependability, and measurability of various motivating conditions distinct from, or only indirectly related to, hunger. Among the possibilities which are receiving attention are the presentation of an object which has come to be strongly desired or treasured by the subject; entertainment reward, in the shape of stimulus-producing mechanisms which may be operated by the subject; social rewards, such as companionship, exercise, social play, commendation or praise by the experimenter; or, the utilization of a token or symbolic incentive, whose value depends upon trained association with food or with some other motivating condition. Doctor Cowles offers in this report a significant contribution to the general subject of token incentives. His study supplements Wolfe's (1936) previously reported investigation concerning the value of tokens. It has now been established that this motivational procedure may be used advantageously for chimpanzee in certain types of experiment"--Foreword.
