Rescorla's research focused on the contingency model of conditioning, which showed that not all stimulus-response pairings result in conditioning. Contingency theory proposes that for learning to take place, a stimulus must provide the subject information about the likelihood that certain events will occur. View scenes from this video on John Watsons experiment in which Little Albert was conditioned to respond in fear to furry objects to learn more.
