Classical conditioning is a vast part of psychology with many underlying models and components. It is defined as the learning process that involves learning a new behavior when two stimuli are paired. The Rescorla-Wagner model is a model that uses the associations between unconditioned stimuli and conditioned stimuli. The model is simple in saying that the CS will predict the US if the association is strong. Once the person has been presented with the CS, they will be less surprised the more it’s repeated. The US will not be as a surprise or shock as it was when the first time it was shown. I had a bit of a hard time grasping the thought of this until I watched this youtube video, although very silly, it gets the point across short and sweet.
