Case Study: The Little Albert Experiment
The Little Albert experiment showed that emotional reactions such as
fear can be taught through classical conditioning.
The Experiment
The Results
• Eleven-month-old Albert was
conditioned to fear a white rat
rather than be amused by it.
• After they paired the rat with loud
noises, Albert showed a fear of the
rat even when there was no noise.
• Psychologists achieved this by
pairing the rat with something
that Albert would find
instinctively frightening.
• By today’s standards, the
experiment was unethical.
• Albert’s fear spread to similar
objects.

Section 1 at a Glance
Classical Conditioning
• Russian psychologist Ivan Pavlov pioneered research
into a form of learning known as classical conditioning. In
classical conditioning, one stimulus causes a response
that is usually caused by another stimulus.
• Classical conditioning can help people adapt to the
environment and can help eliminate troubling fears or
other behaviors.

Learning
Principles of Classical Conditioning
• Conditioning is a type of learning that involves stimulus-response
connections.
• Classical conditioning is a simple form of learning in which one stimulus
calls forth the response that is usually called forth by another stimulus.
Pavlov’s Dogs
Stimulus and Response
• Russian physiologist Ivan Pavlov used
dogs in his studies of classical
conditioning.
• Unconditioned stimulus: a stimulus
that causes a response that is
automatic, not learned
• He trained the dogs to associate the
sound of a bell with food.
• Unconditioned response: caused by
an unconditioned stimulus
• They learned that the sound of the bell
meant food was coming.
• Conditioned response: a learned
response to a neutral stimulus
• Conditioned stimulus: a previously
neutral stimulus that causes a
conditioned response

• One-trial learning
Spontaneous Recovery
• Spontaneous recovery:
Reappearance of an extinguished
conditioned response after some

• Generalization: The tendency to
respond in the same way to stimuli
that have similar characteristics
• Discrimination: The act of
responding differently to stimuli that
are not similar to each other

Applications of Classical Conditioning
Flooding and Systematic
Desensitization
• In flooding, a person is exposed to
the harmless stimulus until fear
responses to that stimulus are
extinguished.
Counterconditioning
• In counterconditioning, a pleasant
stimulus is paired repeatedly with a
fearful one, counteracting the fear.
• With systematic desensitization,
people learn relaxation techniques
and then, while they are relaxed,
they are gradually exposed to the
stimulus they fear.

Section 2 at a Glance
Operant Conditioning
• Psychologist B.F. Skinner helped pioneer research into a
form of learning known as operant conditioning, in which
individuals learn from the consequences of their actions.
• Operant conditioning depends on the use of
reinforcements and a schedule to execute them.
• The principles of operant conditioning can be applied to
help people or animals learn to combine a series of
simple steps or actions to form complex behaviors.

Learning
Operant Conditioning and Reinforcement
• In operant conditioning, people and animals learn to do certain
things—and not to do others—because of the results of what they do.
• They learn from the consequences of their actions.
• In operant conditioning, voluntary responses are conditioned.
• B.F. Skinner studied operant conditioning by using the “Skinner box.”
• His experiment demonstrated reinforcement, or the process by
which a stimulus (food) increases the chances that a preceding
behavior (a rat pressing a lever) will occur again.
• Knowledge of results is often all the reinforcement that people need
to learn new skills.
• Reinforcers always cause the behavior to occur again

Question:
Describe
How does reinforcement result in operant
conditioning?
Answer: In operant conditioning, people and
animals learn to do certain things because of the
results of what they do. Reinforcement increases
the chances that such behavior will occur again.

Types of Reinforcers
Primary and Secondary
Reinforcers
Positive and
NegativeReinforcers
• Primary reinforcers are
reinforcers that function due to the
biological makeup of an organism.
• Positive reinforcers increase the
frequency of a behavior.
• Secondary reinforcers are
learned by being paired with
primary reinforcers.
• Money is a secondary reinforcer
because we have learned that it
may be exchanged for primary
reinforcers like food and shelter.
• In positive reinforcement, a person
receives something he or she
wants following the behavior.
• Negative reinforcers increase the
frequency of a behavior when they
are removed.
• In negative reinforcement, a
behavior is reinforced because
something unwanted stops
happening or is removed following
the behavior.

Summarize
Describe the four main types of reinforcers.
Answer:
1. Primary reinforcers are those that people and animals do not need
to be taught to value, such as food and water.
2. Secondary reinforcers, like money, must be learned.
3. Positive reinforcers, such as food and fun, increase the frequency
of the behavior they follow when they are applied.
4. Negative reinforcers increase the frequency of the behavior that
follows when they are removed. They are unpleasant, and include
discomfort and fear. (something unwanted stops happening after the
behavior)

Rewards and Punishments
Rewards
Punishments
• Like positive reinforcement,
rewards help encourage learning.
• Punishments are quite different
from negative reinforcers.
• Some psychologists, however,
prefer positive reinforcement
because the concept of
reinforcement can be explained
without trying to guess what an
organism will find rewarding.
• Punishments are unwanted events
that decrease the frequency of the
behavior they follow.
• Punishments tend to work only
when they are guaranteed.
• Most psychologists believe it is
preferable to reward children for
desirable behavior than punish
them for unwanted behavior.

Schedules of Reinforcement
• The effectiveness of a reinforcement depends on the schedule of
reinforcement—when and how often the reinforcement occurs.
Continuous and Partial
Reinforcement
Interval Schedules
• Continuous reinforcement is the
reinforcement of a behavior every time
the behavior occurs.
• Fixed-interval schedule: a fixed amount
of time must elapse between
reinforcements (paycheck every Fri)
• Continuous reinforcement is not always
practical or possible.
• The alternative is partial
reinforcement, which means a
behavior is not reinforced every time the
behavior occurs.
• Variable-interval schedule: varying
amounts of time go by between
reinforcements (boss “drops in”)

Ratio Schedule
• Fixed-ratio schedule: reinforcement
occurs after a fixed number of
responses
(food pellet to rat after every 5 tries)
• Variable-ratio schedule:
reinforcement occurs after a
varying number of responses
Extinction in Operant
Conditioning
•
In operant conditioning, extinction
results from repeated
performances of the response
without reinforcement.

Infer
Why are both variable-interval schedules
and variable-ratio schedules successful?
(behaviors learned through partial reinforcement tend to last longer after they
are no longer being reinforced than behaviors learned through continuous
reinforcement)
(tend to maintain that behavior only as long as the reinforcer is there)
Answer: because timing is unpredictable; reinforcement
can come at any time (think pop quizzes)

Three Ways Operant Conditioning Can Be Applied
Shaping and Chaining
Programmed Learning
• Shaping is a way of teaching
complex behaviors in which one
first reinforces small steps in the
total activity.
• Programmed learning is based on
shaping and chaining.
• Chaining is combining the steps of
a sequence to progress toward a
final action.
• Chaining can be forward or
backward.
• Chaining can be used to teach
complex behavior patterns to
people and animals.
• Developed by B.F. Skinner, it
assumes that any task can be
broken down into small steps.
• Programmed learning does not
involve punishments.
• Instead, it reinforces correct
responses.
• Computer “frames” where you can’t
move on until you’ve mastered a
concept

Cognitive Factors in Learning
• Cognitive psychologists focus on the mental aspects of
learning and are interested in what people or animals
know, not just what they do.
• Cognitive learning is based on the idea that people and
animals can learn by thinking or by watching others.
• Some techniques for behavioral modification are based
on the ideas of operant conditioning and cognitive factors.

Pathways to Rewards
Pathways to Rewards is a program that seeks to help improve the lives of
public housing residents in Chicago. The program uses the principles of token
economies and has proved to be highly successful in helping people modify
their behavior through a system of individual goals and rewards.
• The Pathways to Rewards program
is for residents of Henry Horner
Homes in Chicago.
• Residents set monthly goals and
establish the steps needed to reach
them.
• Adults and children may participate
in the program.
• Participants earn points for meeting
their goals.
• The points can be redeemed for
rewards such as merchandise, billpaying assistance, and health club
membership.
• At the end of 2007, 58 percent of
eligible residents had enrolled in
the program.
