Final answer:
Norma, who has internalized rules for good conduct, is likely to be the most independent and trustworthy as she adheres to good behavior based on her own value system.
Step-by-step explanation:
The child who is likely to be considerably more independent and trustworthy is Norma, who has internalized rules for good conduct. When a person internalizes rules, it indicates that they have incorporated the standards and norms of good behavior into their own value system, making it more likely that they will follow these rules even when external authority is absent or when they are not being directly observed. In contrast, Sayuri, who copies her morality from her older brother, may depend too much on external guidance and may not act autonomously. Mick, who is positively reinforced for good behavior, might behave well in anticipation of rewards rather than because of a firm personal commitment to good conduct. Joe, who believes that truth telling is always good, may be ethical but his rigid belief system might not necessarily translate to broad independence or trustworthiness in various situations.
