Research examining relations between language skills and social competence has yielded mixed findings. Three meta-analyses investigated links between language skills (overall, receptive, and expressive) and social competence in 2- to 12-year-old children. Data from 130 studies representing 62,120 children (M age at language assessment = 4.70…

Having one's funding cut in the course of conducting a longitudinal study has become an increasingly real challenge faced by developmental researchers. The main purpose of the current work is to propose "post hoc" planned missing (PHPM) data designs as a promising solution in such difficult situations. This study discusses general…

Fluent conversation requires temporal organization between conversational exchanges. By performing a systematic review and Bayesian multi-level meta-analysis, we map the trajectory of infants' turn-taking abilities over the course of early development (0 to 70 months). We synthesize the evidence from 26 studies (78 estimates from 429 unique…

Indigenous communities practice survivance and challenge social and political systems to support their children's identity and well-being. Grounded in transformative social-emotional learning (SEL) and tribal critical race theory, this 3-year community-based participatory research study (2019-2021) examined how a SEL program co-created with an…

Epigenetics provides the opportunity to revolutionize our understanding of the role of genetics and the environment in explaining human behavior, although the use of epigenetics to study human behavior is just beginning. In this introduction, the authors present the basics of epigenetics in a way that is designed to make this exciting field…

Lester, Conradt, and Marsit (2016) have assembled a set of articles that bring to readers of "Child Development" the scope and impact of the exponentially growing research on epigenetics and child development. This commentary aims to place this work in a broader context of theory and research by (a) providing a conceptual framework for…

Previous work suggests that key factors for replicability, a necessary feature for theory building, include statistical power and appropriate research planning. These factors are examined by analyzing a collection of 12 standardized meta-analyses on language development between birth and 5 years. With a median effect size of Cohen's d = 0.45 and…

Urie Bronfenbrenner and Ernest Boyer argued for leaving the laboratory to conduct rigorous developmental research in the real world where children are found--in the places they go. Contributions to this special issue meet Bronfenbrenner and Boyer's call while at the same time recognizing the continued importance of laboratory research. These…

Parental attitudes shape play opportunities afforded to children in home, community, and school settings. This study presents evaluation of an intervention designed to enrich parent's conception of play and its relationship with socially valued skills and capacities. On the basis of data from 291 racially and ethnically diverse parents/caregivers…

Global concerns about the consequences of disasters, political violence, disease, malnutrition, maltreatment, and other threats to human development and well-being have sparked a surge of international interest in resilience science. This article highlights progress and issues in research that aims to understand variations in human adaptation to…

Exposure to nonionizing radiation used in wireless communication remains a contentious topic in the public mind--while the overwhelming scientific evidence to date suggests that microwave and radio frequencies used in modern communications are safe, public apprehension remains considerable. A recent article in "Child Development" has…

Children's mindsets about intelligence (as a quality they can grow vs. a trait they cannot change) robustly influence their motivation and achievement. How do adults foster "growth mindsets" in children? One might assume that adults act in ways that communicate their own mindsets to children. However, new research shows that many parents…

Fourteen years ago, the first article on molecular genetics was published in this journal: "Child Development, Molecular Genetics, and What to Do With Genes Once They Are Found" (R. Plomin & M. Rutter, 1998). The goal of the article was to outline what developmentalists can do with genes once they are found. These new directions for developmental…

Mind in the Making and Vroom are partner initiatives that exemplify a unique "civic science" approach to "bringing developmental science into the world." Mind in the Making offers families and professionals working with children 0-8 access to developmental research, by engaging them in an active process of professional…

Bayesian statistical methods are becoming ever more popular in applied and fundamental research. In this study a gentle introduction to Bayesian analysis is provided. It is shown under what circumstances it is attractive to use Bayesian estimation, and how to interpret properly the results. First, the ingredients underlying Bayesian methods are…
