There are two key parts. The example we used here is from the first studies on classical conditioning as described by Ivan Pavlov, the famous Russian physiologist. He created the first learning theory which precedes the learning theory most teachers know quite well, reinforcement theory. We will look at reinforcement theory in a separate chapter, but for now I do want to make a point. There is nothing in here about rewards or punishments, no terminology like that, not even an implication like that.
Classical conditioning is built on creating relationships by association over trials.
Some people confuse Classical Conditioning with Reinforcement Theory. To keep them separated just look for the presence of rewards and punishments. This type of influence is extremely common. Sure, the animals come running even if you are opening a can of green beans. They have associated the sound of the opener with their food.
