This study found that young 4-, 5- and 6-year-olds who engaged in more conversation at home had more brain activity and verbal aptitude while they were listening to a story and processing language. The hypothesis is that back-and-forth conversation may rewire the brain and cause it to grow — a hypothesis that will be tested in a future study. In the study, the benefits of conversation were just as strong for low-income children as they were for high-income children. Children who experienced high amounts of conversation scored 12 percent higher on standardized language assessments.
