Research Findings: Prosocial behavior in early childhood can be assessed by various informants and methodologies, but the information each provides may differ in meaningful ways. The present study measured and compared young children's (N = 486; age: M = 48.51 months, SD = 8.22) prosocial behavior based on parent reports, teacher reports, and…

Early writing is a foundational component of emergent literacy. Despite recent increases in early writing research, studies often narrowly focus on transcription (i.e., letter and/or name writing, spelling) to the exclusion of their ability to compose or generate ideas and translate into writing. Research investigating composing approaches it in…

Research Findings: We examined whether Head Start teachers' depressive symptoms are associated with their engagement in high-quality conversations with children, and we considered the extent to which this association is consistent across classroom contexts and activities. Observations of Head Start teachers' conversations with children were…

Research Findings: A total of 54 videotaped mathematics activity observations drawn from 27 different pre-kindergarten classrooms in an urban public schools system in the U.S. were coded using 2 observational measures: (1) a general measure, the Classroom Assessment Scoring System (CLASS); and (2) a math-specific measure, the High Impact…

Research Findings: Measuring toddlers' cortisol levels both in childcare and at home and their relation to child- and childcare-related factors may help to identify stress-inducing childcare practices and children who are more vulnerable to stress in childcare. Accordingly, toddlers' (n = 320, 51.2% female, mean age = 26.8 months) cortisol levels…

Research Findings: Conversing abstract concepts boost children's language learning. Despite the numerous studies on the linguistic environment of early childhood education settings (ECE), most of this work disregards contextual factors that may influence abstract conversations and omits characteristics of children's verbal participation in these…

Research Findings: The present study investigates both the proximal processes and contextual influences on children's oral language development in preschool. We examine whether teacher language practices vary across activity settings and program type, which teacher language practices predict children's oral language skills, and potential…

Research findings: This study examined the dual language development and experience of the understudied Chinese dual language learners (DLLs). Twice in the preschool/pre-k year (about 4 months apart), we assessed 39 Chinese 3- and 4-year-old DLLs' receptive vocabularies in English and Chinese, interviewed 37 parents about the language use and…
