About this trial

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 criteria

Qualifiers

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

Disqualifiers

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)
