Participants in longitudinal studies that followed children into adulthood now have children of their own, which has enabled researchers to establish multiple-generation cohorts. In this article, I illustrate the benefits of multiple-generation cohort studies for developmental researchers, including: (a) the impact of child and adolescent…

A focal goal of development science in recent years has been to document and understand the psychological processes that underlie inequality toward the goal of promoting equity and justice (e.g., Killen, Rutland, & Yip, 2016). This timely special section on economic inequality broadens the empirical conversation, which has centered mostly on…

Georgia's Pre-K Longitudinal Study followed a statewide sample of 1,169 children who attended Georgia's Pre-K Program in 2013-14 through their 4th grade year in 2018-19. The study was conducted by researchers at the Frank Porter Graham (FPG) Child Development Institute at the University of North Carolina at Chapel Hill. The following summary…

In Australia and many other countries, the provision of the healthiest possible start in life for all children has been a priority for government. Evidence to support the importance of the early years for future development has accumulated over the past two decades [1]. Patterns of childhood development predict health, wellbeing, learning and…

In this commentary, Martin Holtmann, discusses Doehnert and colleagues' article in this issue (Doehnert et al., 2013). Holtmann comments that the article illustrates the value of longitudinal electrophysiological and experimental approaches to disentangle different pathways underlying the phenotype of ADHD, and points out that their…

Each year, the Interagency Autism Coordinating Committee (IACC) releases a list of scientific advances that represent significant progress in the field. The "2020 Summary of Advances in Autism Research" provides short, plain language summaries of the top research breakthroughs selected by the IACC from a pool of research articles…

When every child has the opportunity to meet his or her full potential, families, communities, and the nation's economic future strengthens. Remarkably, one in four American children come from low-income families and enter kindergarten not ready to learn and, as a result, fall behind from the very start. The nation pays a heavy price through…

In "A Quality of Giftedness," Professor Joan Freeman reflects upon her long career working as a psychologist in England with gifted children. She gives particular attention to observations gained during the most recent analysis of her longitudinal study that was published in 2010 as Gifted Lives. This work provides an in-depth look at 20…

Concentration is a "sine qua non," a hallmark, of a Montessori Casa program. Yet, it happens that some children do not concentrate. They do not engage with the materials in the classic pattern of normalization. They are not challenged by ADD, ADHD, or a variant of sensory integration spectrum disorder. Instead of working alone, they prefer the…

Longitudinal data analysis has long played a significant role in empirical research within the developmental sciences. The past decade has given rise to a host of new and exciting analytic methods for studying between-person differences in within-person change. These methods are broadly organized under the term "growth curve models." The…

This article hones what is meant by "emergent comprehension". The authors define emergent comprehension as the period when young children, prior to conventional reading, engage in meaningful experiences that stimulate the development and use of meaning-making strategies with potential to affect later reading comprehension. The construct "emergent…

This report provides a portrait of children who entered Head Start for the first time in fall 2009 and completed a year in the program in spring 2010. It also describes their family backgrounds and the classrooms and programs that serve them. Data are drawn from the 2009 cohort of the Head Start Family and Child Experiences Survey (FACES), a…

In longitudinal studies data is collected in a series of waves. Each wave after the first suffers from attrition. Therefore it can be difficult to discriminate between changes in sample parameters due to a longitudinal process (e.g. ageing) and changes due to attrition. The problem is particularly vexing if one of the purposes is to compare…

The article presents 30-year bibliometrical results on trends in the scope, internationality, and impact of the "International Journal of Behavioral Development" ("IJBD") from its inception in 1978 to 2007. Bibliometric data were collected using the databases PsycINFO and Social Science Citation Index (SSCI), and the "IJBD" itself. In comparison…

Five years ago, the editor of "Exceptional Parent" Magazine requested the author to provide an account of a day in the life of the National Children's Study, an ambitious study by the federal government that aims to find out how the environment affects child health and development. Planning and implementation of the National Children's Study has…
