[简答题]Observational Learning
Some scientists believed that direct reinforcement could not account for all types of learning. Bandura’s learning theory added a social element, arguing that people can learn new information and behaviors by watching other people. Known as observational learning (or modeling), this type of learning can be used to explain a wide variety of behaviors. Observational learning takes place when an individual acquires a habit or skill through witnessing the performance of another person. Such learning often, but not always, involves imitation of the observed activities.
Question: The professor uses an experiment to illustrate the definition of "observational learning". Explain how this example is related to the reading passage.
