Learning
Chapter Overview
Will be some of the first Psychology
information you learn in college
 Classical Conditioning
 Operant Conditioning
 Learned Behaviors

I. Classical Conditioning

Definitions to know in this chapter

Conditioning type of learning that involves
stimulus-response connections

Learning  process of learning associations
between environmental stimuli and behavior
responses
I. Classical Conditioning

Classical Conditioning: a form of
learning that involves the use of a stimulus
to generate a specific response

Classical conditioning can help people
adapt to the environment and can help
eliminate troubling fears or other behaviors
I. 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

I. Classical Conditioning
Pavlov’s Dogs – Famous Experiment
 Pavlov used dogs in his studies of
classical conditioning
 He trained the dogs to associate the
sound of a bell with food
 They learned that the sound of the bell
meant food was coming

Stimulus and Response
Unconditioned stimulus: a stimulus that
causes a response that is automatic, not
learned
 Unconditioned response: caused by an
unconditioned stimulus
 Conditioned response: a learned response
to a neutral stimulus

I. Classical Conditioning

Stimulus and Response


Conditioned stimulus: a previously neutral
stimulus that causes a conditioned response
Conditioned Emotional Response (CER)
Emotional responses are classically
conditioned to a previously neutral stimulus
 CyberPsych, Alcohol and Ads Video

I. Classical Conditioning
Adapting to the Environment using CC
 Taste Aversions

Learned response to a particular food
 One-trial learning


Extinction

Disappearance of conditioned response when
unconditioned stimulus no longer follows
conditioned stimulus
I. Classical Conditioning

Adaptation to Environment

Spontaneous Recovery  Reappearance of an
extinguished conditioned response after some time
has passed
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

II. Operant Conditioning
Psychologist B.F. Skinner was a pioneer in
the research of Operant Conditioning
 Operant Conditioning depends on the use
of reinforcements and a schedule to
execute them


Operant conditioning is when people and
animals learn through the consequences of
their behavior
II. Operant Conditioning

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

Operant conditioning will occur when people
or animals have learned to respond to a
certain situation
II. Operant Conditioning

During Operant Conditioning people learn
to continue or eliminate behaviors based
on what happens after the behavior

People learn from the consequences of their
actions

Voluntary responses are conditioned
II. Operant Conditioning


Skinner’s Experiment
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
II. Operant Conditioning

Reinforcement, defined as the
strengthening of a response, will increase
the chances of a behavior being repeated

There are different types of reinforcement

Example  Dog learning to lay down will
receive a treat from the owner
II. Operant Conditioning


Types of Reinforcements
Positive reinforcers increase the frequency of
a behavior when presented


Person receives something he or she wants following
the behavior
Negative reinforcers increase the frequency of
a behavior when they are removed

Behavior is reinforced because something unwanted
stops happening or is removed following the behavior
II. Operant Conditioning


Rewards and Punishments
Rewards  Like positive reinforcement,
rewards help encourage learning


Some psychologists, however, prefer positive
reinforcement
Punishments  Quite different from negative
reinforcers

Punishments are unwanted events that decrease the
frequency of the behavior they follow
II. Operant Conditioning
• The effectiveness of reinforcement
depends on the schedule of
reinforcement
• When and how often the reinforcement occurs
is known as schedule of reinforcement

There are different types of schedules that
can be followed
II. Operant Conditioning

Continuous reinforcement is the
reinforcement of a behavior every time the
behavior occurs


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
II. Operant Conditioning
Interval Schedules
 Fixed - Interval Schedule: a fixed amount
of time must elapse between
reinforcements
 Variable – Interval Schedule: varying
amounts of time go by between
reinforcements


III. 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

III. Cognitive Factors in Learning

Cognitive learning studies multiple factors
including:

How people obtain information

How people process information

Problem Solving Ability
III. Cognitive Factors in Learning
There are several different types of
Cognitive Learning
 Latent Learning is learning that remains
hidden until it is needed


Most psychologists believe that much learning
takes place without reinforcement
III. Cognitive Factors in Learning

Observational Learning  knowledge
and skills acquired by observing and
imitating others
Modeling is a basic form of imitation
 Vicarious reinforcement is the ability to
learn from the experiences of another
 Observational learning and modeling account
for much of human learning

III. Cognitive Factors in Learning
Media Violence  very controversial
issue
 Television is a major source of informal
observational learning


Most health professionals agree that
media violence contributes to aggression
III. Cognitive Factors in Learning

Class Activity

You will be coming up with a different
example of what people (society) have
learned because of the media
