Purpose: Working memory and linguistic knowledge are highly intertwined in language tasks. Verbal working memory in particular has been studied as a potential constraint on language performance. This, in turn, highlights the need for a clinical assessment tool that will assist clinicians in understanding individual children's performance in…

Research Findings Research suggests children from low-income environments have vocabularies that differ from those of their higher-income peers. They may have basic knowledge of many words of which children from higher income environments have acquired sub- or supra-ordinate knowledge. This study sought to determine if children from low-income…

This paper attempts to investigate the repetition of Relative Clauses (RCs) in Mandarin children with Developmental Language Disorder (DLD) (aged 4; 5 to 6; 0) and their typically developing (TD) peers. The results of a sentence repetition task indicate that Mandarin children with DLD perform significantly worse than both groups of TD children,…

Rejection by peers has devastating effects on children's social-cognitive development. As language difficulties have been found to be one of the underlying causes of peer rejection, the present study focused on the relation between these two variables. Specifically, this study was the first to test a hypothesized model connecting children's level…

This article examines factors that promote active multilingualism. For this purpose, the "Peabody Picture Vocabulary Test" was used with 48 children. Their results were linked to a parental questionnaire designed to evaluate the children's linguistic input in their immediate environment. The study shows that, besides a minimum amount of…

Theory of mind describes the ability to engage in perspective-taking, infer mental states, and predict intentions, behavior, and actions in others. Theory of mind performance is associated with foundational cognitive and socioemotional skills, including verbal ability (receptive and expressive vocabulary), executive function (inhibitory control…

We investigated whether individual differences in overall receptive vocabulary knowledge measured at the beginning of the year moderated the effects of a kindergarten vocabulary intervention that supplemented classroom vocabulary instruction. We also examined whether moderation would offset the benefits of providing Tier-2 vocabulary intervention…

This project aimed to describe oral narrative retells of Spanish-English speaking dual language learners (DLLs) and examine relationships with standardized vocabulary assessments. Investigators described oral narrative retells of 145 DLLs in kindergarten and first grade by number of different words (NDW), words per minute (WPM), and…

The present study examines the association of micro- and macrostructural components in narrative retells within and across languages in Spanish-English bilingual Latino kindergarten children. Using a within-subject research design, fourteen Spanish-English speaking Latino kindergarten children were individually read a scripted picture book, after…

This study examined the relative contributions of Latino/a children's (N = 102) school readiness and early literacy skills during kindergarten in predicting first grade reading achievement. By using discriminant function analyses, the current study identified a set of areas to assess that could be used to effectively screen children during…

The contribution of repeated e-book reading with and without word explanation support and its effect on receptive and expressive word learning among preschoolers was examined. Seventy-eight kindergartners were randomly divided into an experimental and a control group. The experimental group received two individual reading sessions of an e-book…

Shared-book reading is a well-established intervention to foster vocabulary development. Factors influencing its effectiveness are, however, less well studied, particularly with regard to story-delivery. We contrasted a read-aloud with a free storytelling approach and tested effects on vocabulary learning. In the first study, 83 preschoolers aged…

In this thesis, I present three related papers that collectively investigate the instructional supports on screen and in the media viewing context that influenced English and heritage language vocabulary knowledge in DLLs. In study 1, I examine how specific pedagogical approaches used in educational media might benefit DLLs. In study 2, I…

Using a nationally representative sample of dual language learners (DLLs) attending Head Start, this study investigated how the language used for instruction and the proportion of DLLs in the class was associated with English and Spanish receptive vocabulary development between the fall and spring (n = 531). Based on teacher report of the language…

A critical skill in emergent writing is the developing ability to take the perspective of different readers; however, the precursors of this skill have not yet been identified. In this longitudinal study, 105 children (90 after attrition) were tested at 3 time points: pre-kindergarten (3-4 years old, n = 105), kindergarten (5 years old, n = 97),…
