ALBERT
BANDURA'S SOCIAL LEARNING
THEORY
Social
Learning theorists explain behavior in
terms of interaction between cognitive,
behavioral and
environmental
determinants. Bandura is a Social
Learning theorist.
Bandura
consider learning principles to be
sufficient to explain and
predict behavior and behavior
change.
The
focus is on interaction, between the external
stimuli and internal cognitions in a
social context.
1-Bandura
suggests most human behavior is learned
by observation. In Modeling we observe
the behavior
of
others and use the information as a
guide for our own
behavior.
2-Bandura
and his colleagues have demonstrated that
subjects allowed to observe a
set of responses
performed
by another individual (the model)
tend
to exhibit these same
responses (model) when placed in
a
similar
setting.
Example:
Our
behavior develops as a result of
observational learning. We observe the
available models
and
imitate these models. Such as
our parents, teachers,
politicians, film heroes,
celebrities and even
fictional
characters like Superman,
Spiderman.

1-BIOGRAPHICAL
SKETCH
Bandura
received his graduate training in
clinical psychology at the University of
Iowa, which awarded
him
the Ph.D. in 1952. After a
year of postdoctoral clinical
training, Bandura accepted, in
1953, a position
at
Stanford University, where he was
professor of Social Science. He has
served as chairman of the
Stanford
Department of Psychology and in 1974 was
elected to the presidency of the American
Psychological
Association. Bandura has
been the recipient of the Distinguished
Scientist Award of the
American
Psychological Association's Division of
Clinical Psychology, the Distinguished
Scientific
Contribution
Award from the American
Psychological Association, and the
Distinguished Contribution
Award
of the International Society for
Research on Aggression.
Bandura
has presented his theory in
a series of books, with the
late Richard Walters as
junior author.
Bandura
(1959) wrote Adolescent
aggression, a
detailed report of a field
study in which social
learning
principles
were used to analyze the personality
development of a group of middle-class
delinquent boys,
followed
by Social
learning and personality development
(1963),
a volume in which he and
Walters
133
Personality
Psychology PSY 405

presented
the social learning principles they had
developed and the evidence on which the
theory was
based.
In 1969 Bandura published
Principles
of behavior modification, in
which he outlined the
application
of
behavioral techniques based on learning
principles to the modification of
behavior, and in 1973,
he
published
Aggression:
A social learning analysis. Social
learning-theory (1977b).in
which Bandura has
"attempted
to provide a unified theoretical
framework for analyzing human
thought and behavior" (p.
vi),
remains
his clearest theoretical
statement to date, although his
Social
foundations of thought and
action
(1986)
provides a more detailed treatment of the
theory. In' addition to
these theoretical
statements,
Bandura
and his students have contributed an
extensive series of empirical
articles.
In
common with most learning
theory approaches to personality, social
learning theory is based on
the
premise
that human behavior is largely
acquired and that the principles of
learning are sufficient to
account
for
the development and maintenance of that
behavior.
In
the course of observing others
behavior, individuals learn to
imitate that behavior or in
some way model
themselves
after others. In their 1941book,
Social
leaning and imitation, Miller
and Dollard had recognized
the
significant role played by
imitative processes in personality
development and had sought to
develop
explanations
of certain kinds of imitative
behavior. Bandura's 1974 article,
"Behavior theories and the
models
of
man,"
provides a
relatively
summary of his point of
view:
"Our
theories have been
incredibly slow in acknowledging
that man can learn by
observation
as well as by
direct
experience. . . .
The
rudimentary form of
learning
based on
direct
experience has been
exhaustively
studied,
whereas the more pervasive and
powerful mode of
learning
by
observation
is
largely
ignored. A
shift
of
emphasis
is
needed.
(p. 863)"
Bandura's
career has been devoted to
encouraging that
shift.
2-
Reconceptualization of Reinforcement
Bandura
greatly broadens the definition of
reinforcement. When people
observe the outcomes of their
own
behavior
and the behavior of others, they develop
hypotheses about the likely
consequences of producing
that
behavior in the future. This
information then serves as a
guide for
subsequent
behavior. Accurate
hypotheses
produce successful
performance, and inaccurate hypotheses lead to
ineffective behavior.
(Notice
the similarity to George Kelly's
point about "construing
replications) In other words,
reinforcers
provide
information about what a
person must do in order to
secure desired outcomes and to
avoid
punishing
outcomes. As a consequence, reinforcement
can only occur when a person
is aware
of
the
contingencies
and anticipates that they will
apply to future behavior. Humans'
ability to anticipate
outcomes
also
accounts for the incentive
value of reinforcers: "By representing
foreseeable outcomes symbolically,
people
can convert future
consequences into current
motivators of
behavior.
Most actions are thus
largely
under
anticipatory control" (Bandura,
1977b, p; 18). For Bandura,
then, a reinforcer functions
primarily as
"an
informative and motivational operation
rather than as a mechanical response
strengthener" (1977b, p.
21).
As a
consequence,
Bandura considers "regulation" to be a
more appropriate term than
"reinforcement."
Bandura
also rejects the Skinnerian
understanding of
how
reinforcement functions. In
observational
learning,
reinforcement serves as "an antecedent"
rather than a "consequent"
influence. That is,
anticipated
reinforcement
is one of
several
factors that can influence
a
person
to pay attention to a model, and it
can
also
encourage a
person
to rehearse the behavior that
has been observed. From Bandura's
point of
view
reinforcement
facilitates learning in an anticipatory
manner by encouraging the observer to pay
attention
and
to rehearse the observed behavior.
Bandura even proposes that
direct reinforcement is not
necessary in
order
for
learning to
occur.
Bandura
adds two other types of
reinforcement to the classical concept of
"direct reinforcement" as
a
stimulus
whose presence increases the
frequency of
occurrence
for a behavior with which it
is paired. First,
"self-reinforcement"
occurs when an individual
compares his or her own
behavior to internal standard.
If
the
behavior meets those
standards, the person may experience
satisfaction, or pride, but if the
behavior
violates
or falls short of those standards
the person responds with
guilt, shame, or
dissatisfaction.
Bandura
is suggesting that any behavior
produces two sets of
consequences: self-evaluations and
external
outcomes.
External consequences have the
greatest effect on behavior
when they are compatible
with self
generated
consequences. Behavior is maintained by
its consequences, but those
consequences are not
only
134
Personality
Psychology PSY 405
VU
externally
applied.
As
a second new type of
reinforcement, Bandura suggests
that "vicarious reinforcement"
occurs when an
individual
witnesses someone else experience
reinforcing or punishing consequences
for a behavior, and
that
individual anticipates similar
consequences if she or he produces the
same behavior, Thus, an
individual
may be reinforced without
producing a behavior or experiencing a
consequence. "Observed
consequences
can change behavior in much
the same manner as directly experienced
consequences". Much
as
Skinner had suggested that
Thorndike's trial-and-error learning
was an inefficient and
unlikely way to
acquire
complex behaviors, so Bandura
suggests that Skinner's operant
conditioning is an Impractical and
dangerous
means for humans to acquire
many behaviors. In contrast, most human
behavior is learned
observationally
by modeling: We observe the behavior of
others and use the information as a
guide for our
own
subsequent behavior. We turn
now to Bandura's description of
modeling.
3-
Principles of Observational Learning
Bandura
(1962, 1977b, 1986) proposes
that a fundamental way
humans acquire skills and
behaviors is by
observing
the behavior of others. Such
observational learning, or modeling, is
governed by four
constituent
processes:
attention, retention, production, and
motivation .
i-
Attentional Process
People
cannot learn anything unless
they pay attention to and
accurately perceive significant features
of the
to-be-modeled
behavior. We are most likely
to pay
attention
to behaviors that are
salient, simple, and
promise
to have some functional value. As a
consequence, a model that is
vivid, attractive, competent, and
seen
repeatedly is more likely to catch
our attention. In addition,
what a person notices is influenced by
his
or
her knowledge base and current
orientation. The characteristics of the
observers also determine
how
much
imitative behavior takes place in a
given situation.
The
characteristics of both the model and
observer often jointly determine what
will occur? A
particularly
informative
study showing the interplay of
model and observer was performed by
Hetherington and
Frankie
(1967) with young children
and their parents. The
Investigators first determined by
observing the
parents
the degree of warmth and nurturance
each expressed toward the
child and which parent
was
dominant
in matters of child care.
Subsequently, the child watched each
parent play with toys and
games
supplied
by the investigator, following which the
child was allowed to play
with the same materials and
the
amount
of his or her Imitative behavior
recorded. Children of both sexes were
much more likely to
imitate
a
warm, nurturant parent than a
cool or punitive one, but the largest
effect was found with
girls whose
mothers
were warm. By and large, the
dominant parent also commanded more
Imitative behavior,
although
when
the father was dominant,
girls imitated the mother
somewhat more than the
father.
ii-Retention
Processes
A
behavior cannot be reproduced unless we have
remembered it by coding it in symbolic
form. Retention
of
observed behavior depends mainly
upon mental Images and verbal
representations. Memory can be
enhanced
by organization of the material and by
rehearsal. The material that
is retained often is transformed
to
correspond to some existing knowledge or
expectation on the part of the
learner.
iii-Production
Process
The
learner must be able to reproduce the
behavior that has been
observed. An observed behavior, no
matter
how well it has been
retained, cannot be enacted without the
necessary skills and
abilities.
Sometimes
the production problem stems
from a lack of the requisite
cognitive or motor skills,
but often It
reflects
the performer's lack of feedback about
what she or he actually is
doing. This is true in
learning
many
athletic skills, but it also
is a frequent problem with social
behaviors. "It can be
extremely
informative,
and unnerving, to see or hear
tapes of our own behavior.
Trial and error, practice, and
feedback
all contribute to what is
often a gradual process of
translating knowledge Into
action.
iv-
Motivational Processes
Bandura's
social learning theory emphasizes the
distinction between acquisition and performance
because
people
do not enact everything they
learn. Performance of observed behavior is
influenced by three kinds
of
Incentives: direct, vicarious, and
self-administered. A learned behavior
will be enacted if it leads
directly
135
Personality
Psychology PSY 405
VU
to
a desired outcome, if it has been observed to be
effective for the model, or if it is
self-satisfying. In other
words,
we are likely to produce a behavior if we
believe that it is in our
best interest to do so.
