[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.

Maybe it’s time for this notion to be forgotten-or at least radically revised.
In the past two years, a series of confusing experiments has forced scientific researchers to rethink this and other assumptions about how memory works. The perplexing results of these experiments remind scientists how much they have to learn about one of the last great mysteri
