Bandura conducted a study that investigated social behaviors if they can be acquired through observation and imitation.
Strengths
The experiment method that was used was precise controlled of variables. The variables were controlled are such as gender, time that the children observed this model and the behavior of the model among others.
Strength of this model is that experiments can be replicated of the experiments. Instructions and standardized procedures were used which allows replicability. (Bandura, 1963 has replicated with changes using videos and results were found similar)
Experiments are only means where cause and effect can be established. This gives room to demonstrate if the model had effect on a child to his/her subsequent behaviors since all the variables apart from the independent variables are controlled.

Weaknesses Low ecological validity. Many psychologists have criticized laboratory studies on imitation. Because the model involves the child and the adult model and this is a very limited in social situations. The child has no interaction with the model and this makes it impossible to influence the model. And also the child and the model are strangers.
Another criticism of this study is that demonstrations are measured immediately. Long-term effects cannot be discovered with such single exposure.

The experiment also sounds unethical we don’t know whether the children suffered long-term consequences or not as a result of this study

2. Children behavior were used to demonstrate this model by doing experiment (bobo doll experiment) which was to establish relationship between their behavior and environment and there consequences. Children observe all people around them and try to adopt the behavior in various ways.
Bandura, Ross and Ross (1961), they tested 36 girls and 36 boys aged between 3-6 years old. The pre-test was done for how aggressive the children were in nursery then later aggressive behavior in different points. Matched pairs design was used to do the experiment. This ratings indicated high reliability correlation that is (r=0.89) suggesting agreement. The individuals who are observed are called models.
Children give attention to some people (model) then they encode their behavior. Then at later time they imitate. From the experiment children learn behaviors in society such as aggression in the process of observation through watching behavior from other people.
3. Reinforcement/Operant condition theory
Part of this theory also describes how the environment can influence his/her behavior. Operation conditioning can be applied to explain variety behavior such as process of learning, addiction and language acquisition.
Skinner is the father of this theory which is based on Thorndike’s law of effect. Skinner introduces this behavior which is reinforced tend to repeat.
Among her experiments she gives an example when people are young they try to smoking in school and this in most case they happened with the crowd probably you hang out with. Positive reinforcement when occurred you were likely to repeat the behavior. But if consequence was that you were caught, with punishment you could be consequently less likely to have smoked.
