Observational study reveals positive associations between white matter tract integrity and reading ability in adolescents, highlighting the neural basis of literacy development.
Across a demographically diverse sample of over 7000 US adolescents, the relationship between white matter tracts and reading skills was evaluated using automated tractometry. Fractional Anisotropy (FA) values within several white matter tracts demonstrated strong positive associations with reading ability. Higher FA values were associated with higher reading scores, as assessed by the NIH Toolbox Oral Reading Recognition Test (TORRT). These relationships persisted even after correction for several potential confounding variables.
