Effects of ratio reinforcement schedules on choice behavior.

Choice behavior under a concurrent VR-FR schedule of reinforcement was investigated in two experiments to test a molar theory of maximization. Hunger-motivated albino rats pressed two bars, one on an FR10 and the other on a VR10 schedule, for a food reward. With the total number of experiences with each bar equated and interalternative switching eliminated during training, the study showed that during the choice test, the animals made significantly more responses to the VR than to the FR alternative, allocating about 75% of their responses to the VR alternative. The results suggest that, given an equal return of reward in the long run, the animals preferred a variable to a constant alternative in a choice situation. The findings are discussed in terms of a molar theory of maximization and a schedule-appropriate behavior interpretation of choice.
