Abstract
College students judged the covariation of noncontingent events in both classical and instrumental conditioning contexts. The type of early contingency and the overall probability of events were varied. The subjects rated the covariation higher in the instrumental conditioning context and in conditions in which the probability of events was higher. The type of early contingency did not consistently affect the magnitude of the ratings. It appeared that the act of responding increased the ratings of covariation in noncontingent situations.
