This study evaluates the effectiveness of the "Parent-child Brain Camp," a 4-week video-based executive functions (EFs) training program for children ages 5-6, through a randomized controlled trial with a pre- and post-test design with 173 Hong Kong children (intervention "ni" = 79, 48.7% girls, M[subscript age] = 69.16 months;…

We explore whether training parents' math skills or playing number games improves children's mathematical skills. Participants were 162 parent-child dyads; 88.3% were white and children (79 female) were 4 years (M = 46.88 months). Dyads were assigned to a number game, shape game, parent-only approximate number system training, parent-only general…

This study investigates whether children's preschool experiences are associated with later achievement via enhanced learning behaviors using data from a German longitudinal study following children (N = 554) from age 3 in preschool to age 8 in second grade. There were two main findings. First, results suggest that more positive learning behaviors…

This study explores children's early academic and self-regulatory skills as potential pathways through which a preschool enrichment program--the Chicago School Readiness Project (CSRP)--may contribute to low-income children's long-term outcomes (N = 466; M[subscript age] at baseline = 4.10 years). We find that CSRP's impact on high school grades…

A randomized controlled trial was used to examine the impact of an attachment-based, teacher-child, dyadic intervention (Banking Time) to improve children's externalizing behavior. Participants included 183 teachers and 470 preschool children (3-4 years of age). Classrooms were randomly assigned to Banking Time, child time, or business as usual…

Head Start (HS) is the largest federally funded preschool program for disadvantaged children. Research has shown relatively small impacts on cognitive and social skills; therefore, some have questioned its effectiveness. Using data from the Head Start Impact Study (3-year-old cohort; N = 2,449), latent class analysis was used to (a) identify…

Data from the Head Start Impact Study (N = 3,185, age = 3-4 years) were used to determine whether 1 year of Head Start differentially benefited children from homes with high, middle, and low levels of parental preacademic stimulation on three academic outcome domains--early math, early literacy, and receptive vocabulary. Results from residualized…

Publicly funded prekindergarten programs have achieved small-to-large impacts on children's cognitive outcomes. The current study examined the impact of a prekindergarten program that implemented a coaching system and consistent literacy, language, and mathematics curricula on these and other nontargeted, essential components of school readiness,…

Based on theoretically driven models, the Chicago School Readiness Project (CSRP) targeted low-income children's school readiness through the mediating mechanism of self-regulation. The CSRP is a multicomponent, cluster-randomized efficacy trial implemented in 35 Head Start-funded classrooms (N = 602 children). The analyses confirm that the CSRP…

This study evaluated the relative effectiveness of home-based, community-based, and state-run early childhood programs across Cambodia. A total of 880 five-year-olds (55% girls) from 6 rural provinces in Cambodia attending State Preschools, Community Preschools, Home-Based Programs, or no programs were assessed twice using the Cambodian…

One year after participating in the Research-based, Developmentally Informed (REDI) intervention or "usual practice" Head Start, the learning and behavioral outcomes of 356 children (17% Hispanic, 25% African American; 54% girls; M[subscript age] = 4.59 years at initial assessment) were assessed. In addition, their 202 kindergarten…

This study examines the efficacy of "ParentCorps" among 4-year-old children (N = 171) enrolled in prekindergarten in schools in a large urban school district. "ParentCorps" includes a series of 13 group sessions for parents and children held at the school during early evening hours and facilitated by teachers and mental health…

Ninety-four Spanish-speaking preschoolers (M age = 54.51 months, SD = 4.72; 43 girls) were randomly assigned to receive the High/Scope Curriculum (control n = 32) or the Literacy Express Preschool Curriculum in English-only (n = 31) or initially in Spanish transitioning to English (n = 31). Children's emergent literacy skills were assessed before…

In 2 studies mothers read wordless storybooks to their preschool-aged children; narratives were analyzed for mental state language. Children's theory-of-mind understanding (ToM) was concurrently assessed. In Study 1, children's (N=30; M age 3 years 9 months) ToM task performance was significantly correlated with mothers' explanatory, causal, and…

Responds to Scarr and McCartney's (1988) Bermudian study. Cites recently published research to support a conclusion that poverty alone does not predict school disadvantage so much as poor parents frequently having low motivation and less than high school graduation. (RJC)
