Longitudinal research on language abilities and social functioning in young children suggests that gains in one domain affect gains in the other. However, few studies have examined inter-relations of language and social functioning jointly among young children diagnosed with autism spectrum disorder (ASD). Pre-verbal toddlers with ASD are a group…

Children are unique humans and experience varied development even though they are of the same gene or the same sex but grow and develop according to their respective characteristics. Of course, this condition also demands adjustments in providing appropriate and varied stimuli and responses. This study aims to observe the growth and development of…

We leveraged nationally representative data from the Panel study of Income Dynamics-Child Development Supplement (N = 3,562) and the Early Childhood Longitudinal study (N = 18,174), to chart the development of working memory, indexed via verbal forward and backward digit span task performance, from 3 to 19 years of age. Results revealed nonlinear…

Self-regulation is thought to show heterotypic continuity--its individual differences endure but its behavioral manifestations change across development. Thus, different measures across time may be necessary to account for heterotypic continuity of self-regulation. This longitudinal study examined children's (N = 108) self-regulation development…

Despite the importance of self-control for well-being and adjustment, its development from early childhood to early adolescence has been relatively understudied. We addressed the development of mother-reported self-control in what is likely the largest and longest longitudinal twin study of the topic to this day (N = 1889 individual children with…

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…

Moving can be a stressful and disruptive event for children, but the associations among the type of move, accompanying neighborhood characteristics, and children's development are less well understood, particularly for elementary school children. In the current dissertation, I developed and tested components of a conceptual model that uses…

In 2006 and then, seven years later in 2013, a small scaled research project was carried out into Christian children's developing perspectives as they encounter sacred text from the context of their home lives (Worsley in Br J Relig Educ 28(3):247-257, 2006, Br J Relig Educ 35(1):55-71, 2013). Fourteen years on in 2020, these same children and…

Studying development processes, as they unfold over time, involves collecting repeated measures from individuals and modeling the changes over time. One methodological challenge in this type of longitudinal data is separating retest effects, due to the repeated assessments, from developmental processes such as maturation or age. In this article,…

Scholars theorize that "opportunity gaps" drive achievement disparities between children born into poverty versus affluence. In a 26-year longitudinal study (N = 814), we examine (a) economic disparity in children's accumulation of opportunities--from birth through high school--at home, childcare, school, afterschool, and in the…

The cognitive functioning of children who experience intimate partner violence (IPV) has received less attention than their emotional-behavioral outcomes. Drawing upon data from 615 (48.4% female) 10-year-old Australian-born children and their mothers (9.6% of mothers born in non-English speaking countries) participating in a community-based…

Girls, more than boys, experience a decrease in the severity of autism symptoms during childhood. It is unclear, however, which specific autistic behaviors change more for girls than for boys. Trajectories of autism symptoms were evaluated using the Autism Diagnostic Observation Schedule-calibrated severity scores (ADOS-CSS). Change in the…

Latent growth curve modeling was used to investigate the longitudinal link between attachment, effortful control (EC), and maladaptive development during middle childhood. In a community sample, children (Time 1: n = 157; M[subscript age] = 10.91) and their mothers were examined three times over a two-year period. Attachment was operationalized at…

Intellectual performance is highly heritable and robustly predicts lifelong health and success but the earliest manifestations of genetic effects on this asset are not well understood. This study examined whether early executive function (EF) or verbal performance mediate genetic influences on subsequent intellectual performance, in 561 U.S.-based…

Many studies examine how bilinguals and monolinguals differ in their executive function abilities at one time-point or cross-sectionally. Fewer examine how these groups of children may differ over time. Using nationally representative data obtained from the Early Childhood Longitudinal Study, Kindergarten Class of 2010-2011 (ECLS-K:2011), this…
