Self-regulation and the development of literacy and language achievement from preschool through second grade

This study found that children who demonstrated self-regulation earlier had higher language and literacy skills throughout preschool to second grade. More specifically, earlier self-regulation trajectories were associated with both higher levels and earlier development of both decoding and reading comprehension, but not faster development. Children with early self-regulation trajectories developed phonological awareness earlier than those with late self-regulation trajectories. Finally, children with early self-regulation trajectories had higher levels of vocabulary than children with intermediate trajectories, but did not differ on the rate or timing of vocabulary development. Findings point to the enduring and interconnected nature of self-regulation and children’s language and literacy development.
