108 kindergarten children served as Ss in lever-pulling experiment. They were divided into 3 incentive groups (Group High, Medium and Low) for "token" training in which incentive values were given according to the incentive conditions. Each of the 3 groups was subdivided into 2 additional groups of immediate (Group IM) and delayed (10 sec) reinforcement (Group D). In each trial, measures of starting and movement time of lever pulling response were taken. For both measures Ss of Groups IM responded faster than those of Groups D. In Groups IM, the higher the incentive, the greater was the movement speed. The data were interpreted in terms of the competing response hypothesis and motivational factor suggested by Spence (1956).
