Bringing induction into reinforcement

Through extended series of experiments we have shown that what was initially called adjunctive (or collateral, or even displacement) behavior (e.g., schedule-induced drinking) in fact responds to similar environmental manipulations as conventional operant behavior (e.g., schedule-controlled lever pressing), and that perhaps in both cases behavior is initially elicited by the delivery of the reinforcer and then is strengthened by it. The dynamic combination of induction by reinforcer delivery (the elicitation part) and reinforcement (the strengthening part) can be seen in recent data on the control of the acquisition of schedule-induced behavior by response-contingent consequences and on the control of behavior by past and future events. Here we will advance on this issue by proposing a chaining model that combines both types of influence on behavior, showing an excellent fitting to steady-state data generated by intermittent food reinforcement schedules in the form of licking a water spout, running on a wheel, entering into the food magazine and pressing a lever. Despite different appearance of behavior and different temporal location, the model does a good job in accounting for the structure and organization of behavior in time.
