Classical conditioning is a type of learning in which a neutral stimulus comes to bring about a response after it is paired with a stimulus that naturally brings about that response.
The conditioned stimulus (CS) does not naturally bring about the response we are interested in.
The unconditioned stimulus, automatically causes a response, such as salivation, to occur.
The unconditioned response, or UCR, is the response that the UCS elicits automatically.
In conditioning, the CS is repeatedly presented just prior to the UCS.
When conditioning is complete, the CS will elicit a response which is called the conditioned response, or CR.
