Which behavior is often exhibited by children with developmental disorders like Fragile X?

Children with developmental disorders such as Fragile X syndrome often exhibit repetitive behaviors, which can include actions like hand flapping, rocking, or other similar movements. These behaviors are not merely fidgety or nervous gestures; they are often coping mechanisms or expressions of anxiety that help the child manage sensory overload or emotional distress.

Repetitive behaviors are characteristic of various developmental disorders and can serve several functions, such as providing a sense of comfort, helping with self-regulation, or acting as a way to communicate when verbal skills are limited. Observing these behaviors can be important for caregivers and educators as they may signal a need for support or intervention tailored to the child's unique challenges.

In contrast, the other answer choices describe behaviors that are less typical for children with Fragile X. While excessive talking and highly social interactions might be seen in some children, they do not align with the behavioral patterns commonly associated with Fragile X and similar developmental disorders. Disruptive conduct may occur in group settings, but it is not a defining trait of the disorder. Focused attention on repetitive behaviors provides a clearer insight into the characteristics of children with Fragile X, as it encapsulates a common experience among individuals with this condition.
