Despite much research examining whether bilingual individuals demonstrate superior executive function (EF) skills compared to monolinguals, the purported bilingual advantage remains controversial. One potential reason for discrepant findings across studies examining the bilingual advantage is the difficulty in matching monolingual and bilingual…

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,…

Publicly funded center-based preschool programs were designed to enhance low-income children's early cognitive and social-emotional skills in preparation for kindergarten. In the U.S., the federal Head Start program and state-funded public school-based pre-kindergarten (pre-k) programs are the two primary center-based settings in which low-income…

This longitudinal study investigates the differences in cognitive and socio-emotional development and academic achievement between children educated in special education classes (N = 37) and regular classes (N = 37). The study is retrospective. The first measurement point was while children were attending play-oriented kindergarten and no decision…

This study examined the degrees of congruence between two early childhood evaluation systems on various quality concepts: the Early Childhood Environment Rating Scale-Revised (ECERS-R) and Zhejiang's Kindergarten Quality Rating System (KQRS). Analysis of variance and post hoc least significant difference tests were employed to show the extent to…

Children from lower socioeconomic (SES) backgrounds tend to be at-risk for executive function (EF) impairments by the time they are in preschool, placing them at an early disadvantage for academic success. The present study examined the potentially protective role of bilingual experience on the development of inhibitory control (IC) in 1146 Head…

As the United States experiences greater income inequality, more and more students experience an early science achievement gap. This study tested several competing theoretical models of early science achievement with a longitudinal sample of 14,624 children who were followed from kindergarten entry to the end of 1st grade. To understand why and…

This study examined the vocabulary development of Norwegian second language (L2) learners with Urdu/Punjabi as their first language (L1) at two time-points from kindergarten to primary school, and compared it to the vocabulary development of monolingual Norwegian children. Using path models, the associations between number of picture books in the…

Children develop linguistic competencies during interactions with more knowledgeable others. Consequently, one way to support this development is by enhancing the home literacy environment (HLE) in which children live. In this study a non-intensive intervention procedure was developed to improve HLE and linguistic competencies of 125 German…

Head Start enhances school readiness during preschool, but effects diminish after children transition into kindergarten. Designed to promote sustained gains, the Research-based Developmentally Informed (REDI) Parent program (REDI-P) provided home visits before and after the kindergarten transition, giving parents evidence-based learning games,…

Young children who listen to music regularly demonstrate better development than those who do not. As children grow, their social, cognitive and physical skills can be enhanced by their relationship with music. The music of Mozart was introduced into the children's environment as a sensory background for the standard curriculum. The purpose of…

Weaknesses in early number skills have been found to be a risk factor for later difficulties in mathematical performance. Nevertheless, only a few intervention studies with young children have been published. In this study, the responsiveness to early support in kindergarteners with most severe difficulties was examined with two different computer…

This study examines the practical and conceptual dimensions of children's play in German and Hong Kong Chinese kindergartens. German ("n"?=?24) and Chinese ("n"?=?24) children (3-6 years) were randomly selected and videotaped during their free play for 5?min continuously on five consecutive days. Play behavior was analyzed by…

Preschool parent interventions may produce downstream benefits if initial intervention gains are sustained and improve later socialization experiences. This study explored associations between initial effects of the REDI (Research-based Developmentally Informed) Parent program and later benefits. A randomized trial involving 200 Head Start…

Using data ("n" = 3,790 with 2,119 in the 3-year-old cohort and 1,671 in the 4-year-old cohort) from 353 Head Start centers in the Head Start Impact Study, the only large-scale randomized experiment in Head Start history, this article examined the impact of Head Start on children's cognitive and parent-reported social-behavioral outcomes…
