Head Start Evaluation and Research Center, Boston University. Report D-III, A Study of Preferences among Qualitatively Differing Uncertainties.
The purpose of this study was to measure nonverbally the preference of alternative responses when the net probability of being rewarded was the same. A demonstration of preference under these circumstances would suggest the ability to control or maintain behavior without explicit administration of a reinforcing agent. Head Start children were used as subjects. They were provided, in the experimental situation, with a two-button console. The right button, when pushed, resulted in the illumination of a yellow light and the dispensing of a penny for every second illumination (a consistent reward schedule). The pushing of the left button would result in a 50 percent chance of the illumination of a red light, which was never followed by reward, and a 50 percent chance of the illumination of a green light, which was always rewarded. Thus, whichever button was pushed, there followed a net 50 percent chance of reward. However, only the right button provided a consistent 50 percent reward. The results indicate that children prefer a consistent reward situation to a reward uncertainty situation. (WD)
