Phonological processing development is considered
essential for reading acquisition. Deficient
phonological awareness is considered a core feature of
the specific learning disability, dyslexia. Despite
being neurobiological in origin, the underlying
mechanisms that lead to deficits in phonological
processing and dyslexia remain elusive. Results support
a positive relationship between myelin content and
performance on a measure of phonological awareness in
very young children. Underlying aspects of phonological
awareness appear related to distinct WM correlates not
only in the frontal subcortical system but also in the
temporal lobe, suggesting involvement of auditory and
visual processing systems as well.
