Section 1

Classical Conditioning

• Classical conditioning is a learning procedure in which associations are made between a neutral stimulus and an unconditional stimulus.

– Ivan Pavlov discovered this type of learning accidentally while using dogs to study the process of digestion.

– Learning is a relatively permanent change in a behavioral tendency that results from experience.

Section 1

General Principles of Classical Conditioning

• Acquisition of a classically conditioned response that occurs gradually and increases each time the CS and US are paired.

• The timing of the association between the conditioned stimulus and the unconditioned stimulus also influences learning.

Page 15: Chapter Menu Chapter Introduction Section 1: Classical ConditioningClassical Conditioning Section 2:Operant ConditioningOperant Conditioning Section 3:

Section 1

General Principles of Classical Conditioning (cont.)

• Pavlov also experimented with generalization and discrimination (using circles and ovals):

– Generalization

– Discrimination

– Extinction

Ivan Petrovich Pavlov

Page 16: Chapter Menu Chapter Introduction Section 1: Classical ConditioningClassical Conditioning Section 2:Operant ConditioningOperant Conditioning Section 3:

Section 1

• If a rest period is given following extinction, the CR may reappear when the CS is presented again but not followed by the US.

• Such a spontaneous recovery does not bring the CR back to original strength, however.

• O. Hobart and Mollie Mowrer discovered a solution to bed-wetting by using classical conditioning.

Section 1

Classical Conditioning and Human Behavior (cont.)

• Classical conditioning is an example of a behaviorist theory.

• Behaviorism is the attempt to understand behavior in terms of relationships between observable stimuli and observable responses.

• Behaviorists are psychologists who study only those behaviors that they can observe and measure.

Section 2

Operant Conditioning

• Operant conditioning

– The term operant is used because the subject operates on or causes some change in the environment.

– The participant in operant conditioning must engage in a behavior in order for the programmed outcome to occur.

Section 2

Reinforcement

• Burrhus Frederic Skinner is the psychologist most closely associated with operant conditioning.

• He believed that most behavior is influenced by a person’s history of rewards and punishments.

Page 29: Chapter Menu Chapter Introduction Section 1: Classical ConditioningClassical Conditioning Section 2:Operant ConditioningOperant Conditioning Section 3:

Section 2

Reinforcement (cont.)

• Reinforcement

– Positive reinforcement occurs when something the animal wants is added after an action.

– Negative reinforcement occurs when something unpleasant is taken away if the animal performs an action.

Page 30: Chapter Menu Chapter Introduction Section 1: Classical ConditioningClassical Conditioning Section 2:Operant ConditioningOperant Conditioning Section 3:

Section 2

Reinforcement (cont.)

• A primary reinforcer is a stimulus that is naturally rewarding, such as food or water.

• A secondary reinforcer is a stimulus, such as money, that becomes rewarding through its link with a primary reinforcer.

D. Sometimes

Page 32: Chapter Menu Chapter Introduction Section 1: Classical ConditioningClassical Conditioning Section 2:Operant ConditioningOperant Conditioning Section 3:

Section 2

Schedules of Reinforcement

• Behavior that is reinforced every time it occurs is said to be on a continuous schedule of reinforcement.

• When positive reinforcement occurs only intermittently, or on a partial schedule.

• Ratio schedules are based on numbers of responses, while interval schedules are based on time.

Page 33: Chapter Menu Chapter Introduction Section 1: Classical ConditioningClassical Conditioning Section 2:Operant ConditioningOperant Conditioning Section 3:

Section 2

Schedules of Reinforcement (cont.)

• Four basic methods, or schedules, of intermittent reinforcement have been studied:

– Fixed-ratio schedule

– Variable-ratio schedule

– Fixed-interval schedule

– Variable-interval schedule

Section 2

Aversive Control

• Aversive control

• Two ways in which unpleasant events can affect our behavior:

– Negative reinforcement

– Punishers—an unpleasant consequence occurs and decreases the frequency of the behavior that produced it.

Page 38: Chapter Menu Chapter Introduction Section 1: Classical ConditioningClassical Conditioning Section 2:Operant ConditioningOperant Conditioning Section 3:

Section 2

Aversive Control (cont.)

• Two uses of negative reinforcement:

– Escape conditioning

– Avoidance conditioning

Page 39: Chapter Menu Chapter Introduction Section 1: Classical ConditioningClassical Conditioning Section 2:Operant ConditioningOperant Conditioning Section 3:

Section 2

• Disadvantages:

– Aversive stimuli can produce unwanted side effects such as rage, aggression, and fear.

– People learn to avoid a person delivering the aversive consequences.

– Punishment is likely to suppress, but not eliminate, bad behavior.

– Punishment alone does not teach appropriate and acceptable behavior.

Section 3

Cognitive Learning (cont.)

• Psychologists have shown that general learning strategies can affect a person’s relationship to the environment.

• If a person has numerous experiences in which his or her actions have no effect, he or she may be taught a general strategy of learned helplessness.

• Martin Seligman believes learned helplessness is a major cause of depression.

Section 3

Cognitive Learning (cont.)

• When people are unable to control events in their lives, they respond in one of the following ways:

– They may be less motivated to act and thus stop trying.

– They may experience a lowered sense of self-esteem and think negatively about themselves.

– They may feel depressed.

Page 51: Chapter Menu Chapter Introduction Section 1: Classical ConditioningClassical Conditioning Section 2:Operant ConditioningOperant Conditioning Section 3:

Section 3

Cognitive Learning (cont.)

• Three important elements of learned helplessness:

– Stability—a person’s belief that the state of helplessness results from permanent characteristics.

– Globality—generalization—a student believing he or she fails tests because he or she is “dumb.”

– Internality—attributing undesirable outcomes to one’s own inadequacies instead of blaming them on external circumstance.

Operant ConditioningWe do not just react to our environment, we behave in ways that seem designed to produce certain environmental changes. For example, I flip the light switch to illuminate a room. I say, “Please, pass the salt,” to get the salt shaker.

Improving Study HabitsStudying effectively is an active process. By using successive approximations (reading one more page each time you sit down to study) and positive reinforcements (rewarding yourself for productive studying), you can improve your study habits. The SQ4R and PQ4R methods are active methods of studying.
