Document Summary
Learning is defined as a relatively durable change in behaviour or knowledge due to experience. Classical conditioning explains how a neutral stimulus can acquire the capacity to elicit a response originally elicited by another stimulus. This kind of conditioning was originally described by ivan. Pavlov, who conditioned dogs to salivate in response to the sound of a tone. In classical conditioning, the ucs is a stimulus that elicits an unconditioned response without previous conditioning. The ucr is an unlearned reaction to an unconditioned stimulus that occurs without previous conditioning. The cs is a previously neutral stimulus that has acquired the capacity to elicit a conditioned response. The cr is a learned reaction to a conditioned stimulus. Classically conditioned responses are said to be elicited. Many kinds of everyday responses are regulated through classical conditioning, including phobias, mild fears, and pleasant emotional responses. Even subtle physiological responses such as immune system functioning respond to classical conditioning.
