I always found classical conditioning to be one the of the most interesting things that could happen unknowingly to someone in their life. Classical conditioning is a learning process that occurs when two stimuli are repeatedly paired; a response that is at first elicited by the second stimulus is eventually elicited by the first stimulus alone. One thing that I found interesting was that they actually formed an episode of the simpsons based on classical conditioning. Classical conditioning was used by Lisa to see if she could cause her brother and a hamster to have the same response. By giving them a shook when they touch food, or in Bart's case a cupcake, they became afraid of these things. It was cool to see that a psychological perspective could be done in a TV show, and allow for the average watcher to understand without having to know about classical conditioning. Classical conditioning is such an amazing thing, and is interesting to see how the mind can think and do different things based on different stimulus.
