Children learn language by listening to speech from caregivers around them. However, the type and quantity of speech input that children are exposed to change throughout early childhood in ways that are poorly understood due to the small samples (few participants, limited hours of observation) typically available in developmental psychology. Here…

While it is established that parental "wh"-questions, as a high-quality language input, are associated with child language outcome, less is known about the role of children's "wh"-questions in their language development. This study examines whether children's "wh"-questions during a dinnertime conversation are…

Purpose: Understanding variability sources in early language interaction is critical to identifying children whose development is at risk and designing interventions. Variability across socioeconomic status (SES) groups has been extensively explored. However, SES is a limited individual clinical indicator. For example, it is not generally directly…

This study employs the Specificity Principle to examine the relative impacts of external (input quantity at home and at school, number of books and reading frequency at home, teachers' degree and experience, language usage, socioeconomic status) and internal factors (children's working memory, nonverbal intelligence, learning-related…

Research indicates that linguistic input from teachers may affect child vocabulary development in preschool and beyond (Dickinson & Tabors, 2001). Currently, there is little research on the relationship between specific teacher language use in individual interactions on child language outcomes for preschool children at risk for academic delays.…

Maternal ostensive naming was investigated in a cross-sectional study of 12 children. Display, demonstration, and pointing were coded with regard to whether and how coexisting speech referred to gesture focus. Maternal input was found to be significantly correlated with children's reported receptive vocabulary. (Author/JL)

To examine language outcomes related to language acquisition and academic readiness, this study followed a group of toddlers with slow expressive language development (SELD) through their kindergarten year. Subjects were 27 children between 20 and 34 months who produced fewer than 50 words or no 2-word combinations on L. Resconla's (1989) Language…
