Attention Deficit Hyperactivity Disorder (ADHD) Practice Test

The answer is identified as spontaneous running or climbing, which is a common behavior seen in hyperactive children. Hyperactivity is characterized by an excess of energy and an inability to stay still, making such spontaneous physical activities frequent occurrences. Children with hyperactive tendencies often find it difficult to engage in activities that require sitting still or maintaining focus for extended periods, thus they may frequently move around and seek physical outlets for their energy.

In contrast, the other choices depict behaviors that are not typical of hyperactive children. Long periods of quiet concentration are generally associated with children who have a more focused or calm demeanor, which does not align with hyperactivity. Careful adherence to rules suggests a sense of control and attention to detail that hyperactive children may struggle with, often being more impulsive. Lastly, procrastination on tasks indicates a delay in action that is not characteristic of the hyperactivity, where children are more likely to act immediately rather than wait or postpone tasks. Hence, the behavior of spontaneous running or climbing is a clearer representation of hyperactivity in children.
