Identify that this process involves cognitive development, meaning children actively construct their understanding of gender rather than just learning through external reinforcement or imitation.

Compare the options given: classical conditioning and reinforcement focus on behaviorist learning, imitation of the same-sex parent is more aligned with social learning theory, and attachment to the primary caregiver relates to emotional bonds, none of which fully capture Kohlberg's cognitive developmental approach.
