Kohlberg's theory is one of the most tested frameworks in developmental psychology because it explains how and why moral reasoning changes across the lifespan—not just what people believe is right or wrong. During adolescence, most individuals transition from the pre-conventional to the conventional level, making this period a critical window for moral growth. You're being tested on your ability to identify which stage a person is operating in based on their reasoning, not their behavior or the outcome of their decision.
Understanding this theory means recognizing the underlying cognitive shifts: from egocentric thinking to social perspective-taking to abstract ethical reasoning. Exam questions often present scenarios and ask you to identify the stage—so don't just memorize the stage names. Know the motivation behind the moral choice at each level. Can you explain why someone at Stage 3 would make a different decision than someone at Stage 5, even if they reach the same conclusion? That's what separates a strong response from a mediocre one.
At this level, moral reasoning centers entirely on the self. Decisions are driven by external consequences—what happens to me? This level is typical of children but can persist into adolescence or adulthood in certain contexts.
Compare: Stage 1 vs. Stage 2—both are self-focused, but Stage 1 is about avoiding negative consequences while Stage 2 is about gaining positive outcomes. If an FRQ presents a child who shares toys only to get something in return, that's Stage 2, not Stage 1.
The conventional level marks a cognitive shift toward understanding and valuing social systems. Moral reasoning now considers relationships, group expectations, and the importance of maintaining social order. Most adolescents and adults operate primarily at this level.
Compare: Stage 3 vs. Stage 4—both value conformity, but Stage 3 focuses on interpersonal approval (What will my friends think?) while Stage 4 focuses on societal order (What if everyone broke this rule?). Adolescents often straddle these two stages.
At this level, individuals reason beyond existing social systems to consider abstract ethical principles. This requires formal operational thinking and is relatively rare—many adults never consistently reach this level.
Compare: Stage 5 vs. Stage 6—both involve principled reasoning, but Stage 5 works within democratic systems to change unjust laws, while Stage 6 may act against laws that violate universal ethics. Think Rosa Parks or Gandhi for Stage 6 examples.
Understanding when and how individuals move through stages is essential for applying this theory to adolescent development.
Compare: Knowing a stage vs. acting on it—a Stage 4 thinker who cheats on a test when peers pressure them illustrates the judgment-action gap. Exam questions may ask you to explain why reasoning level doesn't predict behavior.
Kohlberg's theory has been influential but also widely critiqued. Understanding these criticisms demonstrates sophisticated thinking on exams.
Compare: Gilligan vs. Kohlberg—both describe moral development, but Gilligan's ethic of care emphasizes relationships and responsibility while Kohlberg emphasizes justice and rights. FRQs may ask you to evaluate Kohlberg's theory using Gilligan's critique.
| Concept | Best Examples |
|---|---|
| Pre-conventional reasoning | Stage 1 (punishment avoidance), Stage 2 (self-interest) |
| Conventional reasoning | Stage 3 (interpersonal approval), Stage 4 (law and order) |
| Post-conventional reasoning | Stage 5 (social contract), Stage 6 (universal principles) |
| Self-focused motivation | Stages 1 and 2 |
| Relationship-focused motivation | Stage 3 |
| System-focused motivation | Stage 4 |
| Principle-focused motivation | Stages 5 and 6 |
| Key critique (gender) | Gilligan's ethic of care |
| Key critique (culture) | Western individualism bias |
A teenager refuses to cheat on a test because she's afraid of getting caught and suspended. A classmate refuses because "it wouldn't be fair to students who studied." Which stages are these students demonstrating, and what distinguishes their reasoning?
Compare and contrast Stage 3 and Stage 4 reasoning. Why might an adolescent show Stage 3 reasoning with friends but Stage 4 reasoning when discussing laws?
How would Carol Gilligan critique Kohlberg's placement of "care-based" reasoning? What alternative framework does she propose?
If an FRQ describes someone who breaks a law to protest injustice, what evidence would you need to determine whether they're reasoning at Stage 5 or Stage 6?
Why does higher moral reasoning not always lead to moral behavior? Identify two factors that might create a "judgment-action gap" in adolescents.
