Summary
Dyslexia, an impairment in accurate or fluent word recognition, is the most common learning disability affecting roughly ten percent of children. This proposal capitalizes on cutting edge neuroimaging methods, in combination with reading education programs, to generate a new understanding of how successful reading education shapes the development of the brain circuits that support skilled reading. A deeper understanding of the mechanisms of successful remediation of dyslexia, and individual differences in learning, will pave the way for personalized approaches to dyslexia treatment.

Eligibility Criteria
Inclusion Criteria
- Reading difficulties defined as low scores on standardized measures of reading skills
Exclusion Criteria
- no major contraindication for MRI (braces, metal implants, pacemakers, vascular stents, or metallic ear tubes).
- Because the study involves measurements of reading and language ability, new recruits will be native English speakers.
- Subjects have no history of neurological disorder, significant psychiatric problems
- exclude claustrophobic subjects since an MRI might be uncomfortable for them.
