Learn about the behavioral procedure of classical conditioning, where a neutral stimulus is paired with a biologically potent stimulus to produce a conditioned response. Find out the history, terminology, procedures, and applications of this concept in psychology and biology. Learn how Pavlov discovered classical conditioning in his experiments with dogs and how it works in everyday situations. Find out the terms and concepts of classical conditioning, such as UCS, UCR, CS, and CR, and see examples and videos. a type of learning in which an initially neutral stimulus—the conditioned stimulus (CS)—when paired with a stimulus that elicits a reflex response—the unconditioned stimulus (US)—results in a learned, or conditioned, response (CR) when the CS is presented. For example, the sound of a tone may be used as a CS, and food in a dog’s mouth as a US. After repeated pairings, namely, the tone followed immediately by food, the tone, which initially had no effect on salivation (i.e., was ... In classical conditioning, the initial period of learning is known as acquisition, when an organism learns to connect a neutral stimulus and an unconditioned stimulus.
