Kohlberg’s Theory of Development is associated with

Concept: Lawrence Kohlberg developed a stage theory of moral development (building on Piaget's work), describing three levels – pre-conventional, conventional, and post-conventional – each with two stages, that trace how a person's moral reasoning (judgments of right and wrong) matures with age.

Application: The question asks which developmental domain Kohlberg's theory belongs to. Kohlberg used moral dilemmas (such as the Heinz dilemma) to study how reasoning shifts from an obedience-and-punishment orientation, through a law-and-order orientation, and further through a social-contract orientation, to a universal ethical-principle orientation as a person matures. This progression of ethical reasoning IS moral development, so Kohlberg's theory is classified under Moral Development.

Cross-check: Contrasting with the adjacent developmental domains confirms this:

• Cognitive Development (Piaget's stages – sensorimotor, preoperational, concrete operational, formal operational) describes how thinking and reasoning ability mature in general, not moral judgment.

• Language Development (Chomsky, Vygotsky) describes how vocabulary, syntax, and communication are acquired.

• Social Development (Bandura's social learning theory, Erikson's psychosocial stages) describes peer relationships and social behaviour.

• Moral Development – Kohlberg's own three-level, six-stage framework specifically traces how moral reasoning matures, confirming this classification.
