The document summarizes an experiment called the Bobo Doll Experiment, which demonstrated observational learning in children. In the experiment, children observed an adult playing aggressively with a Bobo doll. The children then imitated the adult's behavior when given the opportunity to play with the doll. This showed that the children had learned the aggressive behavior through observation alone. The document also discusses how mirror neurons in the brain help explain observational learning by activating both when performing and observing an action.
