[Excerpt] Attention is one of the key components of school readiness. We focused our research on school-age children (6 to 12 years old), a critical period when attention problems such as attention-deficit/hyperactivity disorder (ADHD) often become apparent. Yet it is also a time when the brain remains relatively plastic, allowing for intervention if aggravating factors are identified. We surveyed guardians to assess their children's use of short-form video media, total screen time, and observable inattentive symptoms such as forgetfulness, distractibility, difficulty sustaining attention and making careless mistakes.
