Which of the following is considered a behavioral indicator of emotional abuse or neglect?

Failure to thrive is recognized as a behavioral indicator of emotional abuse or neglect because it often signifies that a child is not receiving adequate emotional support, nurturing, or basic needs, which can directly affect their physical and emotional development. This can manifest as growth delays or health issues when a child's emotional and psychological needs go unmet. In cases of emotional neglect or abuse, a child may experience significant stress or lack of trust, leading to an inability to thrive either physically or emotionally.

In contrast, the other options, while they can be associated with various forms of abuse, are not specifically regarded as indicators of emotional abuse or neglect in the same way. Sophisticated sexual knowledge can often signal exposure to inappropriate situations or abuse, but it does not directly demonstrate emotional neglect. Being easily startled might indicate anxiety or trauma, but it is not solely indicative of emotional neglect. Painful punishments fall more squarely under physical abuse rather than emotional abuse. Each of these factors points to different forms of distress or harm a child may face, but failure to thrive specifically encapsulates the broader effects of emotional neglect on a child’s overall well-being.
