The present research extends recent work on the prediction of preschool language skills by exploring prediction from decontextualized vocabulary comprehension. Vocabulary comprehension was a stronger predictor than parent-reported production, yielding a quadrupling of variance accounted for relative to prior studies. Parallel studies (Studies 1…

Toddlerhood is marked by advances in several lexico-semantic skills, including improvements in the size and structure of the lexicon and increased efficiency in lexical processing. This project seeks to delineate how early changes in vocabulary size and vocabulary structure support lexical processing (Experiment 1), and how these three skills…

Previous research has shown that home environment plays an important role in children's early language skills. Yet, few researchers have examined the unique role of family-level factors (socioeconomic status [SES], household chaos) on children's learning or focused on the longitudinal processes that might explain their relations to children's…

In 2 cross-lagged, longitudinal studies we contrasted parental talk about want in a single context versus multiple contexts. Study 1 examined thirty-two 2 year olds, with mothers describing pictures to children. Mothers could use want in zero, one, or multiple contexts. Children whose mothers used want in multiple contexts experienced a…

Although there is evidence that young children's inhibitory control (IC) is related to their academic skills, the nature of this relation and the role of potential moderators of it are not well understood. In this meta-analytic study, we summarized results from 75 peer-reviewed studies of preschool and kindergarten children (14,424 children; 32-80…

Does the language we speak affect the way we think, and if so, how? Previous researchers have considered this question by exploring the cognitive abilities of speakers of different languages. In the present study, we looked for evidence of linguistic relativity within a language and within participants by looking at memory recall for monolingual…

Although children's early language skills have been found to predict literacy outcomes, little is known about the role of preschool oral narrative skills in the pathway between language and emergent literacy or how these associations differ by race/ethnicity and socioeconomic status. The current study uses the Early Childhood Longitudinal Study to…
