Charles darwin survival of the fittest. Learning = is a relatively permanent change in behavior or knowledge due to experience/modification of preexisting behavior and understanding. Pavlov"s experiment with the digestion system of dogs demonstrated what we now call classical conditioning. A procedure in which a neutral stimulus is repeatedly paired with a stimulus that already triggers an automatic, reflexive response until the neutral stimulus alone comes to trigger a similar response. Unconditioned stimulus(ucs) a stimulus that triggers a response without conditioning. Unconditioned response (ucr) the automatic, unlearned, reflexive reaction to a stimulus. Conditioned stimulus (cs) an originally neutral stimulus that now triggers a conditioned response. Conditioned response (cr) the response triggered by the conditioned stimulus. Conditioned response over time: extinction and spontaneous recovery.
