Observational Learning
Observational
learning, also called imitation or modeling, is learning that
occurs when a person observes and imitates someone else's behavior. The
capacity to learn behavior patterns by observation eliminates tedious
trial-and-error learning. In many instances, observational learning takes less
time than operant conditioning.
The Classic Bobo Doll Study
An experiment by
Bandura (1965) illustrates how observational learning can occur even by
watching a model who is not reinforced or punished. The experiment also
illustrates a distinction between learning and performance.
Equal numbers of
kindergarten children were randomly assigned to watch one of three films in
which a person (the model) beat up an adult-size plastic toy called a Bobo
doll. In the first film, the aggressor was rewarded with candy, soft drinks,
and praise for aggressive behavior. In the second film, the aggressor was
criticized and spanked for the aggressive behavior. And in the third film,
there were no consequences for the aggressor's behavior.
Subsequently,
each child was left alone in a room filled with toys, including a Bobo doll.
The child's behavior was observed through a one-way mirror. Children who
watched the films in which the aggressor's behavior cither was reinforced or
went unpunished imitated the aggressor's behavior more than did the children
who saw the aggressor be punished. As you might expect, boys were more
aggressive than girls. However, an important point in this study is that
observational learning occurred just as extensively when modeled aggressive
behavior was not reinforced as when it was reinforced.
A second
important point in this study focuses on the distinction between learning and performance.
lust because students don't perform a response doesn't mean they didn't learn
it. In Bandura's study, when children were given an incentive (with slickers or
fruit juice) to imitate the model, differences in the children's imitative
behavior in the three conditions were eliminated. Bandura believes that when a
child observes behavior but makes no observable response, the child may still
have acquired the modeled response in cognitive form.
Bandura's
Contemporary Model of Observational Learning
Bandura (1986)
has focused on the specific processes that are involved in observational
learning. These include attention, retention, production, and motivation:
* Attention.
Before students can imitate a model's actions, they must attend to what the model
is doing or saying. A student who is distracted by two other students who are
talking might not hear what a teacher is saying. Attention to the model is
influenced by a host of characteristics. For example, warm, powerful, atypical
people command more attention than do cold. weak, typical people. Students arc
more likely to be attentive to high-status models than to low-status models. In
most cases, teachers are high-status models for students.
* Retention. To
reproduce a model's actions, students must code the information and keep it in
memory so that it can be retrieved. A simple verbal description or a vivid
image of what the model did assists students' retention. For example, the
teacher might say, "I'm showing the correct way to do this. You have to do
this step first, this step second, and this step third," as she models how
to solve a math problem. A video with a colorful character demonstrating the
importance of considering other students' lectings might be remembered better
than it (he teacher just tells the students to do this. Such colorful
characters are at the heart of the popularity of Sesame Street with
children. Students' retention will be improved when teachers give vivid,
logical, and clear demonstrations. In chapter 8, we will further examine
the role of memory in children's learning.
* Production. Children
might attend to a model and code in memory what they have seen but. because of
limitations in their motor ability, nut be able to reproduce the model's
behavior. A thirteen-year-old might watch basketball player David Robinson and
golfer Nancy Lopez execute their athletic skills to perfection, or observe a
famous pianist or artist perform their skills, but not be able to reproduce
their motor actions. Teaching, coaching, and practice can help children improve
their motor performances.
• Motivation. Often children
attend to what a model says or docs, retain the information in memory, and
possess the motor skills to perform the action but are not motivated to perform
the modeled behavior. This was demonstrated in Bandura's classic Bobo doll
study when children who saw the model being punished did not reproduce the
punished model's aggressive actions. However, when they subsequently were
given a reinforcement or incentive (stickers or fruit juice), they did imitate
the model's behavior.
Bandura believes
that reinforcement is not always necessary for observational learning to take
place. But if the child does not reproduce the desired behaviors, three types
of reinforcement can help do the trick: (1) reward the model, (2) reward the
child, or (3) instruct the child lo make self-reinforcing statements such as
"Good, I did it!" or "Okay, I've done a good job of getting most
of this right; now if 1 keep trying I will get the rest." We will have
much more to say about such self-management strategies shortly.
As you can see, you
will be an important model in students' lives and you have many
options for providing students with an array of competent models. To evaluate
the roles that models and mentors have played in your own life and can play in
your students' lives, complete Self-Assessment, To explore the
