Unit 5: Learning Corresponding Chapter(s): 6 Topic: Learning (7-9%) LEARNING: SUPPLEMENTARY CHARTS CLASSICAL CONDITIONING: Scheduling the CS and the UCS NOT IN THE MYERS TEXT! KNOW THIS! DELAYED CONDITIONING: Present the CS (bell) first & while the bell is still ringing give the UCS (food). Fastest way to get acquisition. TRACE CONDITIONING: Present the CS (bell), followed by a short break; then present the UCS (food). SIMULTANEOUS CONDITIONING: CS (bell) and UCS (food) are presented at the same time. BACKWARD CONDITIONING: UCS (food) is presented first and is followed by the CS (bell) – definitely NOT the most effective method. Comparing Two Kinds of Conditioning: Classical Conditioning v. Operant Conditioning Classical Conditioning Operant Conditioning End result is the creation of a new response to a stimulus that did not normally produce that response End result is an increase in the rate of an already occurring response Responses are involuntary and reflexive Responses are voluntary Antecedent stimuli are important in forming an association Consequences are important in forming an association Conditioned stimulus (CS) should occur immediately before the unconditioned stimulus (UCS) Reinforcement should be immediate An expectancy develops for unconditioned stimulus (UCS) to follow conditioned stimulus (CS) An expectancy develops for reinforcement to follow a correct response Comparison of Basic Processes in Classical and Operant Conditioning Process and Definition Description in Classical Conditioning Description in Operant Conditioning Acquisition: The initial stage of learning Conditioned stimulus (CS) and unconditioned stimulus (UCS) are paired, gradually resulting in a conditioned response (CR) Responding gradually increases because of reinforcement, possibly through shaping Extinction: The gradual weakening and disappearance of a conditioned response Conditioned stimulus (CS) is presented alone until it no longer elicits conditioned response (CR) Responding gradually slows and stops after reinforcement is terminated Stimulus Generalization: An organism’s responding to stimuli other than the original stimulus used in conditioning Conditioned response (CR) is elicited by a new stimulus that resembles the original conditioned stimulus (CS) Responding increases in the presence of a new stimulus that resembles original discriminative stimulus*** Stimulus Discrimination: An organism’s lack of response to stimuli that are similar to the original stimulus used in conditioning Conditioned response (CR) is not elicited by a new stimulus that resembles the original conditioned stimulus (CS) Responding does not increase in the presence of a new stimulus that resembles original discriminative stimulus ***Discriminative Stimulus: Cues that influence operant behavior by indicating the probable consequences (reinforcement or non reinforcement) of a response. OPERANT CONDITIONING: Four Ways to Modify Behavior (Reinforcement v. Punishment) Reinforcement Punishment Positive (Adding) Something valued or desirable Positive Reinforcement Example: Getting a gold star for good behavior in school Something unpleasant Punishment by Application (or positive punishment) Example: Getting a spanking for disobeying Negative (Removing/Avoiding) Something unpleasant Negative Reinforcement Example: Avoiding a ticket by stopping at a red light Something valued or desirable Punishment by Removal (or negative punishment) Example: Losing a privilege such as going out with friends OPERANT CONDITIONING: Negative Reinforcement vs. Punishment by Removal (Comparison in Examples) Examples of Negative Reinforcement Examples of Punishment by Removal Stopping at a red light to avoid getting in an accident Losing the privilege of driving because you got into too many accidents Submitting a homework assignment on time to avoid being penalized Receiving a low grade on an assignment because it was turned in late Obeying a parent before the parent reaches the count of “three” to avoid getting a scolding Being “grounded” because of disobedience KEY STUDIES IN LEARNING Classical Conditioning Operant Conditioning PAVLOV Dogs salivating to neutral stimuli THORNDIKE Cats solving problems in a puzzle box (Law of Effect and Instrumental Learning) WATSON Little Albert (rat, noise, fear) SKINNER Skinner Box RESCORLA Different conditions of pairing bell with shock for dogs; learning depended on a contingency between bell and shock (predictability) Cognitive Learning SELIGMAN Dogs not being able to escape from shock, then not trying when they could escape TOLMAN Rats wander in mazes; demonstrate quicker learning KOHLER Oberserving chimps solve problems to get fruit BANDURA Children watching others rewarded or punished for hitting Bobo doll.
