According to the reference in our text book, we can easily conclude that "learning" means the change in organism' s behavior or thought as a result of experience, and it is constituded by two major part - classical conditioning and operant conditioning . During this article , I would like to focus on classical contioning and make a analysis about it .
The so-called classical conditioning is a form of learning in which animals come to respond to previously neutral stimulus that had been paried with another stimulus that elicits an automatic response. During the process of classical conditioning, there are four main factors act to finish the whole works : unconditioned stimulus , unconditioned response, conditioned stimulus, conditioned response. Unconditioned stimulus refers to the stimulus that elicits an automatic response, which is the unconditioned response-- automatic response to a nonneutral stimulus that does not need to learn . And the conditioned stimulus means the initial neutral stimulus that comes to elicit a response due to assosiation with an uncondtioned stimulus , and the conditioned response states the response which previously assosiated with a nonneutral stimulus that is elicited by a neutral stimulus through conditioning. Well , I draw a picture to state the relationship among them so that we can understand better and clearlier.
In conclusion, the classical conditoning is a process of stimulus generation, which follows the law of continguity: behaivor change due to stimulus-stimulus continguity.
There are some links to give more evidences of classical conditioning.
