Final answer:
An individual emphasizing the welfare of others in decision-making aligns with the stage of 'mutual interpersonal expectations, relationships, and conformity' in Kohlberg's conventional level of moral development.
Step-by-step explanation:
An individual who emphasizes others rather than himself or herself in making decisions is demonstrating characteristics of Kohlberg's Theory of Moral Development at the conventional level, specifically at the stage of mutual interpersonal expectations, relationships, and conformity.
According to Kohlberg, there are three levels of moral reasoning—preconventional, conventional, and postconventional. In the conventional level, individuals are concerned about the expectations of societal relationships and the need to maintain these relationships through appropriate behavior. This includes being sensitive to others and conforming to social norms that ensure positive interpersonal relationships. Kohlberg identifies the conventional level with adolescents who have developed the cognitive abilities to understand and integrate social relationships into their moral reasoning, distinguishing it from self-centered reasoning (preconventional) and from reasoning based on universal ethical principles (postconventional).
Thus, the stage of moral development the question refers to is b. Mutual interpersonal expectations, relationships, and conformity.
