STUDY GOAL: To investigate how children learn math and how the brain basis underlying mathematical abilities changes over time.
PARTICIPANTS SHOULD BE:
- Right handed
- Between the ages of 5 and 14
- Without braces
- Up to $350 for completing the study
- Pictures of their brain for each year of participation
- A Stanford Brain Development t-shirt
The study consists of 3 inital appointments followed by 1-year and 2-year follow-up appointments. Each year of participation includes the following appointments:
Appointments 1 and 2: Neuropsychological testing
During the first two appointments your child will undergo a series of neuropsychological assessments performed by Stanford assessors. The assessments include measures of IQ, reading, memory and math abilities. These appointments will last 1.5 to 2 hours each.
Participants are compensated $25 for completing each of these 2 neuropsychological appointments, for a total of $50.
Appointment 3: MRI scan
During the third appointment, participants will undergo a brain scan (MRI). During the scan, participants will play computer-based math and memory games while pictures of their brain are taken. An MRI scan is a safe, non-invasive procedure that does not use x-rays or radiation. This appointment lasts 2.5 hours to 3 hours and participants are compensated $50.
Years 2 and 3 Follow-Ups:
Participants return to repeat appointments 1-3 one-year and two-years after their initial visit. Compensation is equal to that of the initial appointments, with a total of $300 possible over the 3-year period.
For full completion of the study, participants are compensated an additional $50, for a total of $350.
