A defining feature of Pavlovian conditioning is that the unconditioned stimulus (US) is delivered whether or not the animal performs a conditioned response (CR). This has lead to the question: Does CR performance play any role in learning? Between the 1930's and 1970's, a consensus emerged that CR acquisition is driven by CS-US experiences, and that CRs play a minimal role, if any. Here we revisit the question and present two new quantitative methods to evaluate whether CRs influence the course of learning. Our results suggest that CRs play an important role in Pavlovian acquisition, in such paradigms as rabbit eyeblink conditioning, pigeon autoshaped key pecking, and rat autoshaped lever pressing and magazine entry.
