Cognitive Control in ADHD

Seeking right-handed children with ADHD aged 9 to 12 as well as right-handed children aged 9 to 12 who have undergone a typical developmental trajectory

The study investigates dynamic brain mechanisms underlying cognitive control in children with ADHD and its relation to inattention and impulsivity.

Participants receive:

  1. Up to $160 for completing the study
  2.  Pictures of their brain

The study consists of 3 appointments:

Appointments 1: Clinical Interview

During the first appointment, your child will complete a series of clinical assessment questionnaires administered by Stanford assessors. The first appointment will last approximately 3 hours. Participants will be compensated $50 for completing the appointment.

Appointments 2: Neuropsychological Assessment


During the second appointments, your child will complete a series of neuropsychological assessments administered by Stanford assessors. The assessments include measures of IQ, reading and math abilities. The second appointment will last approximately 3 hours. Participants will be compensated $50 for completing the appointment.

Appointments 3: MRI Scan


Participants will undergo a brain scan (MRI). Pictures of their brain will be taken while they complete computer-based cognitive control tasks. An MRI scan is a safe, non-invasive procedure that does not use x-rays or radiation. This appointment will last approximately 4 hours, including 1 hour mock scanner session and 3 hours MRI/fMRI scan session. Participants will be compensated $60 for completing both mock scanner and the MRI/fMRI scan sessions.

The clinical and neuropsychological assessments will take place at our offices at 1070 Arastradero Road in Palo Alto.  MRI scans will take place at the Lucas Center on Welch Road and Pasteur Drive. To see where the sessions are located, please click here.
