Observational learning, a key concept in social cognitive theory, plays a significant role in the acquisition of new behaviors. This learning occurs not only through direct experience but also by observing the actions and consequences of others. In a classic experiment conducted by Albert Bandura, children were exposed to a model exhibiting aggressive behavior towards a Bobo doll. The results demonstrated that children imitated the aggressive behaviors they witnessed. In this context, consider the factors that influence observational learning. Which of the following factors is most pivotal in determining whether an individual will imitate a behavior observed in others?
