One important concept from our lectures that I found interesting was Pavlov's Classical Conditioning. This procedure was conducted by Ivan Pavlov and his assistants who would introduce various items and measure the saliva production created by those products. For example, the experimenters would expose dogs to the constant ticking of a metronome and then immediately present them with food. The food was the unconditioned stimulus because it creates an automatic response. The metronome was considered the neutral stimulus, which eventually became a conditioned stimulus, provoking a conditioned response such as salivation. He concluded that salivation was a learned response, because test subjects responded to the sights they saw within their environment. This discovery led to the formation of behavioral psychology, which is helpful today in treating many disorders.
