Document Summary
Unconditioned stimulus (ucs) a stimulus that automatically elicits a response. (like food) Unconditioned response (ucr) a response to an unconditioned stimulus. (like salivating) Conditioned stimulus (cs) a previous neutral stimulus that can now elicit a response (like a bell) Conditioned response (cr) a response to a conditioned stimulus (like salivating to a bell) Conditioned fears are often the result of classical conditioning. Acquisition- the initial stage of learning something; in classical conditioning, it occurs by pairing an. Unconditioned stimulus with a neutral stimulus (like meat and a bell). Extinction- the gradual weakening and disappearance of a conditioned response tendency. In classical conditioning, the conditioned stimulus is presented alone. Spontaneous recovery- reappearance of an extinguished response after a period of nonexposure to that stimulus. Taking a break and getting the response back. Stimulus generalization- responds the same way to similar stimuli(bridge phobia) Stimulus discrimination- responds only to the original stimulus.
