Final answer:
In the preconventional stage of moral development, individuals are concerned with external rewards and personal consequences of an action.
Step-by-step explanation:
In what stage of personal moral development is a person mostly concerned with external rewards and personal consequences of an action? According to Lawrence Kohlberg's theory of moral development, the stage where a person is primarily concerned with external rewards and personal consequences is the preconventional stage. This is the first level of moral development, typically seen in young children who lack higher-level cognitive abilities and understand the world primarily through their senses. They base their understanding of 'right' and 'wrong' on direct consequences to themselves, such as punishment or reward.
Kohlberg's theory progresses from preconventional to conventional, where individuals begin to consider societal norms and rules, and eventually to postconventional, where morality is understood in more abstract terms and considers principles that may conflict with legal rules. The question you are asking specifically relates to the preconventional stage, where individual perspective is determined by direct external rewards and personal consequences.
