The moral development of children and adolescents also plays a role in character and personality development. There are different theories that psychologists use to study behaviorism and personality development in human beings. Then behaviorism theory focuses on children’s past experiences and how they influence different behaviors in growing children (Berger, 2002).
Psychologists use the cognitive theory to study how children process information. Through the cognitive theory, psychologists can gauge and monitor children’s reasoning capacities and problem solving capabilities. The psychoanalytic theory explores the importance of some unconscious mental processes such as fantasies, desires and immature wishes to developing children (Berger, 2002). These theories are the most important in studying and explaining how personalities are developed in children and adolescents.
