Document Summary
Stimulus s response r outcome o. In the case of thorndike"s puzzle box, s is the box, r is the sequence of movements needed to open the door, and o is the escape. The s-r association is strengthened when r is followed by a desirable outcome o. The two type of learning are fundamentally different, as concluded by b. f. skinner. Classical conditioning: organisms experience an outcome (us), whether or not they have learned the conditioned response (cr) Operant conditioning: the outcome o is wholly dependent on whether the organism performs the response r. Deciding between classical and operant conditioning paradigm depends on the outcome. If the outcome occurs regardless of responding, then it"s classical conditioning. If the outcome is contingent on a response, then it is operant conditioning. Both classical and operant conditioning also share many characteristics. Shows extinction: tendency for learned responses to extinguish if no longer paired with an outcome. Thorndike"s procedures were characterized by discrete trial paradigms.
