Final answer:
Albert Bandura's Bobo doll research confirmed that children can learn aggression through observational learning, especially when aggressive models are not punished.
Step-by-step explanation:
In the classic Bobo doll research conducted by Albert Bandura and his colleagues in 1961, it was demonstrated that aggression can indeed be acquired through observational learning. This study provided evidence that children imitate the aggressive actions of adults, especially when the behavior of the adult is not punished. Bandura's experiment involved a scenario where a teacher showed aggression towards a Bobo doll, and this behavior was then copied by the children who observed it. The children were more likely to replicate the aggressive behavior when the teacher received no punishment or was praised. This research has had significant implications for understanding the processes of learning and the role of modeled behavior in the transmission of aggression.
