ABSTRACT

Language interaction between parents and pre-school infants and children is extremely important as children’s brains are developing at a speed they will never approach again. High-quality interaction enhances child language development, which in turn predicts better performance later in school and employment. Parents commonly overestimate how much they talk with their pre-school children, so some form of structured feedback is needed to help them to see the possibilities. The Language Environment Analysis (LENA) system automatically analyses large amounts of parent-child language interaction and yields quantitative feedback that can cause parents to enhance their interactions. This chapter focuses on how parents can be encouraged to engage in high-quality language interaction with their pre-school children in relation to adult word count but particularly in relation to conversational turns. Parents below average in language interaction showed significant and sustained gains. The chapter looks at studies in the United States, but also in China and Korea, examining universal imperatives irrespective of the actual language involved. LENA is now being introduced into schools, although detailed evaluation is awaited.
