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.
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
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.

Classical Conditioning and Human Behavior
• John B. Watson and Rosalie Rayner used conditioning on a human infant in the case of Little Albert.
• O. Hobart and Mollie Mowrer discovered a solution to bed-wetting by using classical conditioning.
Examples of Common Conditioned Responses
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.

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.

D. UR is elicited
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.
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.
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.

Do you agree with the following statement “Extinction will occur if a dog does not receive his treat after shaking hands.”
A. Yes
B. No
C. Not sure
D. Sometimes
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.
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.
Section 2
Aversive Control (cont.)
• Two uses of negative reinforcement:
– Escape conditioning
– Avoidance conditioning
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
• Two examples of cognitive learning:
– Latent learning
– Cognitive maps
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.
Learned Helplessness
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.
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.

Figure 1
Classical Conditioning ExperimentPavlov’s students used this apparatus. The tube leading from the dog’s mouth allowed saliva to be measured and recorded on the kymograph.
Figure 2
Examples of Common Conditioned ResponsesIf you have pets and feed them canned food, what happens when you use the can opener? The animals may come running even when you are opening a can of peas.
Figure 3
Classical Conditioning vs. Operant ConditioningClassical conditioning and operant conditioning both involve the establishment of relationships between two events. Classical conditioning and operant conditioning, though, use very different procedures to reach their goals.
Figure 4
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.
Figure 5
Partial Schedules of ReinforcementB.F. Skinner pointed out many examples of how schedules of reinforcement maintain and control different behaviors. The different schedules produce different response rates.
Figure 6
Learned HelplessnessWhat happens when it is impossible for a learner to have an effect on the environment? What happens when a learner is punished and cannot escape the punishment? The learner may give up trying to learn.
Figure 7
How Social Learning WorksSocial learning theorists argue that much learning results from observing the behavior of others and from imagining the consequences of our own behavior.
Figure 8
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.

Vocab1
classical conditioning: a learning procedure in which associations are made between a neutral stimulus and an unconditioned stimulus
Vocab2
neutral stimulus: a stimulus that does not initially elicit any part of an unconditioned response
Vocab3
unconditioned stimulus (US): an event that elicits a certain predictable response typically without previous training
Vocab4
unconditioned response (UR): an organism’s automatic (or natural) reaction to a stimulus
Vocab5
conditioned stimulus (CS): a once-neutral event that elicits a given response after a period of training in which it has been paired with (occurred just before) an unconditioned stimulus
Vocab6
conditioned response (CR): the learned reaction to a conditioned stimulus
Vocab7
generalization: responding similarly to a range of similar stimuli
Vocab8
discrimination: the ability to respond differently to similar but distinct stimuli
Vocab9
extinction: a gradual disappearance of a conditioned response when the conditioned stimulus is repeatedly presented without the unconditioned stimulus
Vocab10
operant conditioning: learning in which a certain action is reinforced or punished, resulting in corresponding increases or decreases in occurrence
Vocab11
reinforcement: stimulus or event that follows a response and increases the likelihood that the response will be repeated
Vocab12
primary reinforcer: stimulus that is naturally rewarding, such as food or water
Vocab13
secondary reinforcer: stimulus such as money that becomes rewarding through its link with a primary reinforcer
Vocab14
