Final answer:
The stage that reflects concrete interests of the individual in terms of rewards and punishments in Lawrence Kohlberg's theory is the preconventional stage, whereas the conventional stage is where children begin considering societal norms regarding morality.
Step-by-step explanation:
According to Lawrence Kohlberg's stages of moral development, the stage that reflects concrete interests of the individual considered in terms of rewards and punishments is the preconventional stage. At this level, morality is typically understood by children as a system based on pain and pleasure, where good behavior is associated with being rewarded and bad behavior with being punished. This is compared to the later stages, where individuals' understanding of morality is more sophisticated, taking into account societal norms in the conventional stage and abstract principles in the postconventional stage. Kohlberg's theory suggests that as people mature cognitively, their reasoning behind moral decisions evolves from self-interest to recognizing broader social and ethical principles. As for question 3, what occurs in Lawrence Kohlberg's conventional level is c. Children begin to consider what society considers moral and immoral. In the conventional stage, typically developed during early adolescence, morality is based on understanding and adhering to social norms and expectations. Here, individuals are motivated by the desire to maintain social order and gain approval from others.
