What is it about?

We found that children who had better oral language skills in preschool also had better oral language skills in primary school, as well as better writing skills in high school. We also showed that this stability, from oral to written language, from preschool to high school, was mainly explained by children’s genetic background.

Why is it important?

Children who are genetically at risk for oral language difficulties early on are also at risk for writing difficulties later on. This genetic stability in linguistic skills should be considered in intervention programs, especially since writing skills in adolescence are a good indicator of later economic and social success.


As my work usually focuses on children, this study gave me a closer look at what happens with children when they become adolescents, and at the impacts that their more or less optimal development might have on their functioning in real life.
