Document Summary
Classical conditioning: learning predictable signals: we learn to associate two stimuli. Operant conditioning: learning about consequences: we learn to associate a response and its consequence. Operant conditioning type of learning in which the probability of a response is changed by a change in its consequences. Push button, perform complex task: operates (acts) on environment, produces consequences. B. f. skinner (1904-1990: elaborated thorndike"s law of effect, formulated radical behaviorism, developed behavioral technology. Psy 103, topic 22: wrote beyond freedom and dignity. Skinner box: soundproof chamber with a bar or key that an animal can manipulate to obtain a food or water reinforcer, contains a device to record responses. Reinforcer: any stimulus that, when made contingent on a response, increases the probability of that response, positive reinforcement. A behavior is followed by the presentation of an appetitive stimulus, increasing the probability of that behavior: negative reinforcement. A behavior is followed by the removal of an aversive stimulus, increasing the probability of that behavior.
