Which of the following is an indicator of infantile behavior in children that may suggest abuse?

The presence of bizarre, sophisticated, or unusual sexual behavior or knowledge in children is a significant indicator of infantile behavior that may suggest abuse. Typically, children develop a natural curiosity about sexual behaviors and relationships within the context of their age-appropriate experiences. When a child exhibits sexual knowledge or behaviors that are not aligned with their developmental stage, it may indicate exposure to inappropriate or harmful situations.

Such indicators can stem from a range of abusive contexts, including sexual abuse, and warrant a thorough investigation. Recognizing these behaviors as red flags is crucial in child welfare practices, enabling professionals to take the necessary steps to protect the child and address any potential harm.

In contrast, the other options reflect normal developmental milestones or community engagement that do not suggest abuse. For example, the ability to read and write, consistent academic improvement, and involvement in community service are all signs of positive growth and achievement, rather than indicators of distress or abuse.
