Final answer:
People at the preconventional level of Kohlberg's model of moral development base their decisions on potential personal gains or losses.
Step-by-step explanation:
According to Kohlberg's model of moral development, people at the preconventional level make decisions based on what they believe they will get or lose by making a particular decision. During this stage, morality is developed by pain and pleasure, with children experiencing the world only through their senses and valuing actions based on their direct consequences. The preconventional level is the first of Kohlberg's three levels of moral reasoning, which also include the conventional and postconventional levels. As individuals progress in their moral development, they begin to consider societal norms and laws in the conventional level, and eventually reach the postconventional level, where they think in abstract terms and recognize that legality and morality do not always correspond.
