resultsResearch over the last three decades has documented evidence for the differential amount and quality of children’s early language exposure, referred to as the “word gap.” This gap has been associated with family socioeconomic factors and has important consequences for children’s later vocabulary, literacy and school performance. Given the profound social, academic, and economic costs that may result when young children do not have ample language-learning opportunities, it is of primary importance to prevent inequities in language experience. With renewed interest in finding solutions to the word gap, this Special Issue is organized around a series of literature syntheses analyzing the state of language intervention research. Reviews of intervention studies conducted with parents, early educators and healthcare providers, and with culturally and linguistically diverse participants, as well as reviews of training and implementation practices, and methodological factors that inform intervention are described. Ten featured empirical studies document the efficacy of communication and language interventions and illustrate promising practices designed to improve outcomes for infants and young children from disadvantaged backgrounds.
conclusionsBased on the findings described in this compilation of articles, we provide some summary highlights and future directions for research addressing the word gap. First, we review the evidence for the word gap and discuss the literature to date in this area.
