Which theory suggests that moral reasoning develops in stages from simple to complex?

Cognitive Development Theory, particularly as proposed by Jean Piaget, outlines the process by which individuals progress through different stages of cognitive maturation, including moral reasoning. This theory posits that children move from a simplistic understanding of morality to more sophisticated concepts as they grow and experience more of the world around them.

In this framework, moral reasoning evolves through identifiable stages. Initially, young children may see right and wrong as absolute, often based solely on outcomes. As they mature cognitively, they begin to grasp the nuances of morality, understanding not just the outcomes but also the intentions behind actions. Thus, the theory highlights that moral reasoning is not static but rather develops through interactions and cognitive growth, reflecting an increasing complexity in how individuals understand moral issues.

The other theories mentioned do not focus primarily on the development of moral reasoning in stages. Behaviorism emphasizes observable behavior and the influence of the environment on learning, while Social Learning Theory concentrates on imitation and modeling rather than inherent cognitive developments. Erikson's Psychosocial Development Theory examines psychosocial challenges rather than solely focusing on cognitive maturation and moral development.
