Learning by Observation: Module 19
 Bandura’s Experiments
 Applications of Observational Learning
Learning by Observation
Among higher animals, especially humans,
 learning does not occur through direct
 experience alone. Observational learning also
 plays a part. The process of observing and
 imitating a specific behavior is often called
 modeling. Mirror neurons, located in the
 brain’s frontal lobes, demonstrate a neural
 basis for observational learning.

Mirror Neurons
Mirror neurons help give rise to children’s
 empathy and to their ability to infer another’s
 mental state (aka theory of mind). As adults,
 we often feel what another feels, and we find
 it harder to frown when viewing a smile than
 when viewing a frown.
Mirror Neurons
  Neuroscientists discovered mirror neurons in the brains of
  animals and humans that are active during observational
                          learning.

Here you see the pain imagined by an empathic romantic partner triggers
some of the same brain activity experienced by the one actually having the
pain. Brain activity related to actual pain is mirrored in the brain of an
observing loved one. Empathy in the brain shows up in emotional brain
areas, but not in the somatosensory cortex, which receives the physical pain
input.                            http://www.youtube.com/watch?v=Sv1qUj3MuEc

Bandura's Experiments
Bandura's Bobo doll study
(1961) indicated that
individuals (children) learn
through imitating others who
receive rewards and
punishments. Bandura found




                                   Courtesy of Albert Bandura, Stanford University
that we are likely to imitate
actions that go unpunished. We
tend to imitate models that we
perceive to be successful,
admirable or similar to us.
Applications of Observational Learning


        Unfortunately,
     Bandura’s studies also
      show that antisocial
        models (family,
     neighborhood or TV)
      may have antisocial
        effects as well.

Positive Observational Learning
  Fortunately, prosocial (positive, helpful) models may
have prosocial effects which can counteract the antisocial
                           ones.

Prosocial Models
Prosocial models have prosocial effects. People
  who show nonviolent, helpful behavior
  prompt similar behavior in others. Models are
  most effective when their actions and words
  are consistent. Exposed to a hypocrite,
  children tend to imitate the hypocrisy by
  doing what the model did and saying what
  the model says.
Albert Bandura has shown how modeling can eliminate
  undesirable behaviors. In one study nursery school children,
  chosen because they were terrified of dogs, merely watched a
  little boy playing happily with a dog for 20 minutes. As a
  result of this experience, 67 percent were willing to climb into
  a playpen with a dog and remain confined there petting and
  scratching the dog while everyone else left the room. Their
  observations seemed to have a lasting positive effect. One
  month later the children were more willing than ever to
  approach dogs. Subsequent research has indicated that filmed
  models have the same effect. The greatest reduction in fear
  occurred when the film clips depicted a variety of other
  children interacting with their dogs. Observational learning
  may be strongest when we perceive many performing the
  same action.
Filmed models have been used in therapy for diverse problems. Socially
   withdrawn children watched a variety of scenes in which a clearly shy
   child is treated positively when he interacts in a social activity. The
   impact was obvious. After watching the film, the shy children began to
   interact with their peers at a level equal to that of other children in the
   school.
Our tendency to imitate the behavior of others is exploited in a variety of
   settings. For example, television executives seem to know what they
   are doing when they use canned laughter. Experiments indicate that the
   technique causes an audience to laugh louder and more often when
   humorous material is presented. Advertisers love to tell us that their
   product is the “fastest growing” or “largest selling.” The fact that many
   others are using it prompts us to buy it. Bartenders salt their tip jars
   with a few dollar bills to demonstrate appropriate customer behavior.
   The producers of charity telethons devote a great deal of time to listing
   the viewers who have already pledged contributions on the premise that
   others will follow suit.
Television and Observational Learning

  Gentile et al., (2004)
shows that children in
elementary school who
 are exposed to violent
television, videos, and
  video games express
 increased aggression.




                                          Ron Chapple/ Taxi/ Getty Images
Correlational studies that link viewing violence with violent
  behavior do not indicate the direction of influence. Those
  who behave violently may enjoy watching violence on
  TV, or some third factor may cause observers both to
  behave violently and to prefer watching violent programs.
  To establish cause and effect, researchers have designed
  experiments in which some participants view violence
  and others do not. Later, given an opportunity to express
  violence, the people who viewed violence tend to be more
  aggressive and less sympathetic. In addition to imitating
  what they see, observers may become desensitized to
  brutality, whether on TV or in real life.
Modeling Violence
 Research shows that viewing media violence
leads to an increased expression of aggression.

Parental Monitoring of Media Violence
In a review of the research literature, Craig Anderson and
   colleagues highlight the important role of parental monitoring
   and guidance in reducing the harmful effects of media
   violence. They conclude that the impact of media violence
   can be reduced “if parents guide their children’s media
   exposure and discuss their interpretation of media violence
   with their children.” Research suggests that when parents
   speak negatively about violent TV or restrict viewing of
   violent television content, children show less aggressive
   attitudes. On the other hand, if parents watch TV with their
   children and say nothing about the violent content, children
   demonstrate stronger aggressive attitudes.
Parental Monitoring of Media Violence
This analysis clearly reaffirms the importance of the following
  guidelines for parents that an American Psychological Association
  task force on television issued in 1992:
• Maintain an activities time chart, including TV viewing, playing
  with friends, and homework. Discuss what to eliminate as well as its
  substitute.
• Establish a weekly viewing limit. Have children select programs
  from television schedules at the beginning of the week. Assign
  points to specific programs and set a point total for the week. Less
  desirable programs may cost more to watch.
• Rule out TV at certain times, say, at mealtimes or on school nights.
• Encourage the entire family to make a program choice before
  turning on the TV.
• Remember that you provide a model. If you watch a lot of TV,
  chances are that your children will, too.
Parental Monitoring of Media Violence
  In monitoring the violence children see, the task force
     suggests that caregivers:
  • watch at least one episode of the programs their
     children watch to know the frequency and degree of
     violence.
  • when viewing violence with children, discuss why it
     occurs and how painful it is. Ask how conflict might
     be resolved without aggression.
  • explain how violence on programs is faked.
  • encourage children to view programs with characters
     who cooperate and care for each other.
