The Relationship

AbstractThree experiments examined human rates and patterns of responding during exposure to various schedules of reinforcement with or without a concurrent task. In the presence of the concurrent task, performances were similar to those typically noted for nonhumans. Overall response rates were higher on medium-sized ratio schedules than on smaller or larger ratio schedules (Experiment 1), on interval schedules with shorter than longer values (Experiment 2), and on ratio compared with interval schedules with the same rate of reinforcement (Experiment 3). Moreover, bout-initiation responses were more susceptible to influence by rates of reinforcement than were within-bout responses across all experiments. In contrast, in the absence of a concurrent task, human schedule performance did not always display characteristics of nonhuman performance, but tended to be related to the relationship between rates of responding and reinforcement (feedback function), irrespective of the schedule of reinforcement employed. This was also true of within-bout responding, but not bout-initiations, which were not affected by the presence of a concurrent task. These data suggest the existence of two strategies for human responding on free-operant schedules, relatively mechanistic ones that apply to bout-initiation, and relatively explicit ones, that tend to apply to within-bout responding, and dominate human performance when other demands are not made on resources.

Free Operant Situation

Rats were trained to bar press for food reinforcement in a two-bar multiple fixed-ratio situation. After the animal had established asymptotic rates of time for transferring between bars and responding on each bar, responding on one bar led to no reinforcement or random intermittent (50%) reinforcement. Responding on a second bar was always reinforced. Under both schedules of reinforcement, rats decreased their time to transfer to the second bar and their time to respond on the second bar. All animals also displayed an initial disruption of transfer back to and responses on the first bar. For rats on the intermittent reinforcement schedule, the decreased response time on the reinforced bar was primarily found after nonreinforcement of response to the previous bar. Reinforcement schedules for response to the first bar did not differentially affect the above behavior.
