Abstract
This comprehensive longitudinal study explored for the first time the interrelations between neonatal brainstem abnormalities, focused attention (FA), and learning-following a preterm cohort (N = 175; 46.3% female; predominantly White) from birth (2003-2006) to 17 years. The findings indicated that FA during early childhood was associated with language outcomes in toddlerhood (n = 131) and academic and attention self-report indices in late adolescence (n = 44). Pilot assessments indicated that FA at 17 years (n = 25) was also associated with concurrent academic and attention functioning. Structural equation modeling analyses revealed that neonatal brainstem functioning, manifested in auditory brainstem response patterns, was associated with early-life FA competence, which affected learning development. Implications underscore the essential role of early brainstem function and FA in shaping childhood learning trajectories.
