Phonological Awareness and Rapid Object Naming are related to Reading Skills. In this work,
the correlation between performance in the first variables with the development of the Left Inferior
Longitudinal Fascicle was studied. For this, a novel method of Magnetic Resonance was used without
the need for sedation in boys and girls from 3 to 5 years of age. Orthotropic-radial hypothesis contrasts
were performed to test whether the entire fasciculus was part of the correlation or there were more
closely associated radial and longitudinal divisions (hypothesis of non-homogeneity of white matter
tracts). The evidence supported that only some parts of the fascicle had a significant correlation with the
cognitive variables of interest.
