Answer:
Assimilation
Step-by-step explanation:
The human being constantly receives information from the world around him. Once you receive sudden information that breaks your thinking and goes beyond you, it takes time to assimilate the information and accept what happened.
Assimilation shows the capacity for self-improvement that every individual has through intelligence and will, faculties that allow a person to adapt to change. That's what happened to Jake, the assimilation allowed him to adapt to the change of his doll.
