Attention is the first component of observational learning. Individuals cannot learn much by observation unless they perceive and attend to the significant features of the modeled behavior. Retention is the next component. In order to reproduce the modeled behavior, the individuals must code the information into long-term memory. Therefore, the information will be retrieval.
Memory is an important cognitive process that helps the observer code and retrieve information.
In the Bobo doll experiment, the children imitated the aggression they witnessed in the video. They aggressively hit the Bobo doll because it was coded and store in their memory. Motor reproduction is another process in observational learning. The observer must be able to reproduce the model's behavior. The observer must learn and posses the physical capabilities of the modeled behavior.
