Research keeps uncovering how crucial the first months, let alone years, of a child's development are to later school success. In a new paper published in the journal Child Development, Penn State researchers looked at a sample of 8,650 U.S. children and assessed their vocabularies at 24 months. The children were again assessed in kindergarten. Those with "more words," or higher levels of oral vocabulary, at age two had better math and language skills and also had fewer behavioral problems when they entered kindergarten. According to the study, the researchers' intention was to test whether the strength of a child's early vocabulary skills could predict his or her behavior and academic skills in kindergarten, with the goal of identifying children in need of early intervention. Researchers also identified characteristics that are known to be associated with lower oral vocabulary, including being the child of a single parent, lower socioeconomic status, and low birth weight. The study's authors point to the need for early intervention that focuses on increasing vocabulary in at-risk children in their earliest months: "Vocabulary gaps are evident even by this very early time period, and in turn consistently predict children's academic and behavioral functioning as they begin kindergarten."
