Attention-Deficit/Hyperactivity Disorder (ADHD) is characterized by persistent and chronic inattention and/or excessive motor restlessness and impulsivity. Inattentive symptoms include poor organizational skills, making careless errors, forgetfulness, trouble listening, and distractibility. Hyperactive/impulsive symptoms include restlessness, excessive talking, and interrupting. For the purpose of diagnosis, symptom manifestation should be developmentally inappropriate and exhibited in two or more settings (e.g., home and school). Much of the research in the past decade has focused on deficits associated with the disorder in regard to executive function, response inhibition, cognitive control, and motivational dysfunction in response to delayed reinforcers.
