Abstract
The satiation and valence positions concerning reinforcer effectiveness were outlined and certain hypotheses derived from them were tested. 80 2nd graders were administered a socially reinforced task following exposure to 1 of 3 experimental treatments: positive social contact (P), negative social contact (N), and no social contact. Of the Ss in the P and N treatments, ½ were given the criterion task immediately after preliminary contact, and ½ after a delay of 1 wk. The significant interaction between the delay and treatment variables (p < .005) indicated that the delay variable was 1 source of inconsistency in earlier findings. The significant ordering of treatments in the delay condition (p < .005) lent support to the valence position. The study indicated that children's positive and negative reaction tendencies towards E were important factors in determining his effectiveness as a reinforcing agent.
