In Lecture, we learned about Pavlov's Classical Conditioning. There are four parts to this; unconditioned stimulus, unconditioned response, conditioned stimulus, and conditioned response. The unconditioned stimulus can be something like food for example. The unconditioned response is how a person responds to the unconditioned stimulus. In class, we learned an example of this may be a dog salivating around food. The conditioned stimulus is something that is present every time the dog eats, like a sound made right before his food is served. The condition response is his response to the sound made; he salivates. Since he always hears the sound before he eats, he knows food is coming by the sound. The thought of the food causes him to salivate.
I went to camp one year, and before every meal a bell would ring. The bell always made me hungry, because I knew food was coming. Eventually, the bell started being used for other things, like when free time began or when we had a meeting. At first, I would always feel hungry and expect to eat. After a while, I grew accustomed to the bell being used for different things and no longer felt hunger after every ring.
We become familiar with certain sounds at certain points in are day. We begin to associate them with things like food or people. Classical conditioning is all about how we respond to our environment. It is natural to respond to food by salivating. The reason the dog salivated when he heard the metronome was because he associated it with the food. Just like he grew accustomed to the sound coming before a meal, when the meal stopped coming after the sound he eventually became accustomed to that too. So, if we associate something with something else, but they no longer are together, we can just as easily unassociated them.
