The purpose of the study is to examine the developmental trajectory of response control in boys and girls with ADHD entering adolescence. The investigators also want to determine the developmental trajectory of brain anatomy and brain connectivity in boys and girls with ADHD entering adolescence.
Children with Attention Deficit Hyperactivity Disorder (ADHD) are at risk for a host of deleterious outcomes including impaired social relations, academic difficulties, criminality, and comorbid psychopathology (substance use, depression, anxiety). Many of these difficulties emerge and exacerbate during adolescence; therefore, it is crucial to understand the developmental trajectory of ADHD-associated changes in brain and behavior during this sensitive period. Further, there is increasing recognition that sex may be an important moderator of the clinical manifestations of ADHD, with adolescent boys showing more impulsive risk-taking while girls show more emotional dysregulation. Identification of patterns of brain and behavioral development associated with risk for poor outcome in both boys and girls with ADHD shows the profound public health significance of our research. Furthermore, the investigators are proposing to examine the dimensional construct of response control in children with ADHD from multiple levels of analysis including neural structure and connectivity, behavioral expression, and relation to functional outcomes, with the ultimate goal of identifying bio-behavioral markers of impairment and adjustment in children with ADHD. Our objectives: Aim 1: To examine the developmental trajectory of response control in boys and girls with ADHD entering adolescence. Aim 2: To examine how baseline abnormalities in response control and brain structure and function, as well as development trajectories for these measures, differentially predict functional outcomes in adolescent boys and girls with ADHD. Aim 3: To examine how intrinsic functional connectivity relates to brain structure, structural connectivity, and response control in adolescent boys and girls with ADHD.

Response Control and Frustration Tolerance
Go/No-Go (GNG) reaction time task related to working memory and motivation. Each task will take place in a single block of 207 trials (80% green), with no rest phases (total duration = 8min, 19 sec). For the motivational GNG task, stimulus presentation will be followed by a blank screen (1000ms), the presentation of visual feedback (1700ms), and another blank screen (500ms). Reward feedback will be presented for correct "go" responses and response cost feedback will be presented for commission errors.
Time frame: Completed on Day 1 or Day 2 Visit
Developmental Trajectory of Brain Anatomy
The Primary outcome variables will be morphometry of cortical regions (thickness, surface area, folding index, volume) and subcortical regions (basal ganglia, amygdala, and hippocampus volume and shape).
Time frame: Completed on Day 1 or Day 2 Visit
Predictors of Adolescent Socio-Emotional Development
Behavior Assessment System for Children (BASC-3) is a questionnaire used to assess behavioral and emotional functioning in children. The parent-report, teacher-report, and self-report versions will be administered to collect behavioral and emotional values.
Time frame: Completed on Day 1 or Day 2 Visit
Developments of ADHD Symptoms
Conners-4 is a questionnaire to values on conduct and learning problems, impulsivity-hyperactivity, anxiety, and social competence. Parent-report and teacher-report will be administered collect values to determine ADHD symptom severity.
