Step 1: Understanding the Concept:
Lawrence Kohlberg's cognitive-developmental theory of moral development outlines how individuals reason about moral dilemmas as they grow older.
Kohlberg presented children and adults with hypothetical moral dilemmas (such as the famous Heinz dilemma) and analyzed the underlying reasoning behind their choices.
His theory proposes that moral development progresses through a series of distinct levels and stages, driven by cognitive growth and social role-taking opportunities.
Step 2: Detailed Explanation:
Let us evaluate each of the given statements:
(A). Levels of moral reasoning:
This statement is true.
Kohlberg identified three major levels of moral reasoning: Preconventional (Level 1), Conventional (Level 2), and Postconventional (Level 3).
Each level contains two distinct stages, resulting in six stages of moral development.
(B). Progression through stages:
This statement is false.
While Kohlberg believed that individuals progress through the stages in a fixed, invariant sequence, he did not believe that everyone reaches the highest stage.
His research showed that many adults never progress beyond the conventional level (Stage 4), and only a small percentage of the population reaches the highest postconventional stage (Stage 6).
(C). Postconventional morality:
This statement is true.
Postconventional morality is indeed the third level of moral development, characterized by an individual's understanding of abstract, universal ethical principles that may transcend local laws.
(D). Role of social experiences and reasoning:
This statement is true.
Kohlberg's cognitive-developmental perspective emphasizes that active moral reasoning and social experiences (such as interacting with peers and encountering different perspectives) drive moral development.
Therefore, statements (A), (C), and (D) are true, while statement (B) is false.
Step 3: Final Answer:
Hence, the correct option representing the true statements is (A), (C), and (D) only.
