Stanford University
180 participants
May 5, 2023
INTERVENTIONAL
Conditions
Summary
The purpose of this study is to investigate neurocognitive mechanisms underlying response to intervention aimed at enhancing, and remediating weaknesses in, numerical skills in children, including those with mathematical learning disabilities (MLD).
Eligibility
Inclusion Criteria6
- Elementary school aged children starting from first grade (6-12 years old)
- IQ: Participants with a Full Scale IQ \> 70 on the Wechsler Abbreviated Scle of Intelligence (WASI-II).
- Identification of Mathematical Learning Disabilities: Scores below the 35th percentile percentile on symbolic number processing test in Numeracy Screener and two or more Wechsler Individual Achievement Test (WIAT-IV) math subtests
- Identification of typically developing children: Scores at or above the 35th percentile percentile on symbolic number processing test in Numeracy Screener and all WIAT-IV math subtests
- Normal or corrected-to-normal vision and no hearing impairments
- Inclusion in MRI scan session: Right-handed
Exclusion Criteria4
- History of neurological or psychiatric disorder (i.e., schizophrenia, psychosis, depression, or attention deficit hyperactivity disorder.)
- History of trauma involving head injury
- Consistent psychiatric medications
- Exclusion from MRI scan session: No major contraindication for magnetic resonance imaging (MRI) - braces, metal implants, pacemakers, vascular stents, metallic ear tubes, consistent exposure to metal, claustrophobia)
Interventions
After study participants have completed screenings to meet our inclusion criteria, participants will take part in the pre-training MRI brain scan (if eligible) and behavioral assessments and will then be assigned to the intervention for 6 weeks. During this training, participants will spend three days each week completing a set of problems at their home on a tablet that we provide them. Participants will receive one-to-one training with a member of our research team once a week. Following the completion of the 6-week training program, participants will be asked to complete a second MRI brain imaging session (for those who completed pre-training MRI) and post-measure appointments in order to assess immediate effects of the training program. Participants will also be invited to return for follow-up testing after six months in order to assess the long- lasting effects of the training program.
