Interventions in Math Learning Disabilities: Cognitive and Neural Correlates
Stanford University
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).
Description
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). To achieve this goal, investigators will use a theoretically-motivated integrated symbolic/non-symbolic (iSNS) intervention with a randomized controlled design to enhance cross-format mapping between symbolic and nonsymbolic representations of quantities. The investigators will develop innovative computational models to investigate individual diff…

Interventions
- OtherInterventions in Mathematics and Cognitive Skills - Experimental
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.
