Comparing choices and variations in people and rats: two teaching experiments.
Two pairs of experiments enabled students to compare their own operant behaviors with those of rats. The students played computer games for points, and the rats pressed levers for food. The first pair of experiments showed that, under concurrent schedules of reinforcement, relative frequencies of choices between two alternatives increased linearly in rats and people as functions of relative frequencies of reinforcement, with similar biases and undermatching observed in both species. The second pair of experiments showed that behavioral variability was controlled by reinforcers contingent on variability, this again true for both species. These experiments helped demonstrate the relevance of animal operant research to an explanation of human operant behavior.
