Research Findings: The aim of this study was to construct and validate "English Picture Vocabulary Test (EPVT)" that aimed to assess the very young learners' (VYLs) receptive and expressive vocabulary knowledge for specific content areas in English as a foreign language (EFL). In this context, EPVT was created in several stages. One of…

This study evaluated the emergent literacy profiles of preschool Spanish-speaking children. Participants included 440 children in dual-language classrooms who were assessed in English and Spanish at the beginning and end of their preschool year. Research Findings: Through latent profile analysis, conducted with fall data, four empirically derived…

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…

Research Findings: This study considered the interplay between infant temperament and maternal caregiving behaviors in relation to early language. A total of 118 mother-infant dyads participated in the study. Mothers rated infant positive affect (PA) and negative affect (NA), and maternal behaviors were coded during a free-play task when infants…

Research Findings: The present study compared effects of explicit instruction on and practice with the phonological form of words (form-focused instruction) versus explicit instruction on and practice with the meaning of words (meaning-focused instruction). Instruction was given via interactive storybook reading in the kindergarten classroom of…

This study examined the concurrent relations of English (EL) and heritage language (HL) proficiency to executive functions (EF) among low-income dual language learners (DLLs) from immigrant families. In a sample of 90 children (age = 38-70 months) from Chinese-speaking Chinese American and Spanish-speaking Mexican American families recruited from…

Research Findings: Mental state verbs (MSV), a component of literate and academic language, may facilitate vocabulary growth, as they relate to metacognitive and metalinguistic awareness as well as decontextualized talk, all of which have been associated with vocabulary growth. In this study, we examined teacher MSV use in group content…

The purpose of the present study was to examine associations among English and Spanish emergent literacy skills of prekindergarten (pre-K) Spanish-speaking dual language learners in relation to their English invented spelling. Study participants included 141 Spanish-speaking 4-year-old children enrolled in state-funded pre-K programs in a large…

Research Findings: This study examines lexical- and sentence-level dimensions of academic language to describe teachers' natural use of academic language and its association with vocabulary growth in 489 at-risk 4-year-olds enrolled in Head Start preschool classrooms. Using transcripts derived from video recordings of book-reading sessions in 52…

Research Findings: The present cross-sectional study investigated the question of whether 6 different temperament dimensions (inhibition to novelty, social orientation, motor activity, positive emotionality, negative emotionality, and attention) influenced cognitive and affective theory of mind (ToM) in 168 children (86 three/four-year-olds and 82…

Research Findings: I examined the long-term association between the lexical and acoustic features of maternal utterances during book reading and the language skills of infants and children. Maternal utterances were collected from 22 mother-child dyads in picture book-reading episodes when children were ages 6-12 months and 5 years. Two aspects of…

Research Findings: Grounded in the investment model and informed by the integrative theory of the study of minority children, this study used the Early Childhood Longitudinal Study-Birth Cohort data set, a nationally representative sample of young children, to investigate whether the association between socioeconomic status (family income and…

Research Findings: As policymakers expand access to preschool, the sociodemographic composition of preschool classrooms will become increasingly important. These efforts may create programs that increase the concentration of children from low-income families or, alternatively, foster the creation of socioeconomically diverse preschool classrooms.…

Research Findings: Environmental print provides children with their earliest print experiences. This observational study investigated the frequency of mother-child environmental print referencing and its relationship with emergent literacy. A total of 35 mothers and their children (ages 3-4 years) were videotaped interacting in an environmental…

This study examined the relation between language skills, gender, and relational/physical aggression. Language skills of 100 preschoolers were assessed with 3 standardized instruments. Relational/physical aggression was rated by the children's teachers. Results indicated that relational and physical aggression tended to increase as language scores…
