Classical conditioning

• classical conditioning is the process of learning to associate a stimulus with a response
• unconditioned stimulus (UCS) is a stimulus that is not learned to be associated with a response
• unconditioned response (UCR) is an automatic, unlearned response to a UCS
• neutral stimulus (NS) is a stimulus that does not naturally elicit a response
• conditioned stimulus (CS) is a previously neutral stimulus that has been paired with another stimulus so it now triggers a response
• conditioned response is the response to a conditioned stimulus that is not present in the absence of the unconditioned stimulus
• extinction is the loss of a conditioned response to a stimulus that has not been reinforced
• spontaneous recovery is when a conditioned response is reinstated after a period of no stimulation
