Preterm birth poses a major public health challenge, with significant and heterogeneous developmental impacts. Latent profile analysis was applied to the National Institutes of Health Toolbox performance of 1891 healthy prematurely born children from the Adolescent Brain and Cognitive Development study (970 boys, 921 girls; 10.00 ± 0.61 years;…

Williams syndrome (WS) is a rare genetic syndrome. As with all rare syndromes, obtaining adequately powered sample sizes is a challenge. Here we present legacy data from seven UK labs, enabling the characterisation of cross-sectional and longitudinal developmental trajectories of verbal and non-verbal development in the largest sample of…

Background: Limited information about school outcomes among children (especially early childhood) with lifetime history of head injury, including traumatic brain injury (TBI), may inhibit efforts to support their academics and physical and mental health. Methods: Baseline data (2016-2018) from the Adolescent Brain Cognitive Development (ABCD)…

Prior evidence shows that early childhood education (ECE) can serve as a protective factor that boosts maltreated children's school readiness outcomes. Yet, less is known about ECE's relationship to other developmental domains critical to their wellbeing including their adaptive behaviors and cognitive development. Focusing on a broader range of…

Working memory training improves children's cognitive performance on untrained tasks; however, little is known about the underlying neural mechanisms. This was investigated in 32 typically developing children aged 10-14 years (19 girls and 13 boys) using a randomized controlled design and multi-modal magnetic resonance imaging (Devon, UK;…

In the past, researchers would consider media's impact on youth in terms of three "Cs": consumption, content, and context. This article introduces a new construct--constancy--which supplants the previous terms. Constancy refers to the ubiquitous and continuous state of connected screens in the lives of children and adolescents. Constancy…

Throughout childhood and adolescence, humans experience marked changes in cortical structure and cognitive ability. Cortical thickness and surface area, in particular, have been associated with cognitive ability. Here we ask the question: What are the time-related associations between cognitive changes and cortical structure maturation.…

In the last century, Jean Piaget proposed one of the most famous theories regarding cognitive development in children. Piaget proposed four cognitive developmental stages for children, including sensorimotor, preoperational, concrete operational, and the formal operational stage. Although Piaget's theories have had a great impact on developmental…

This prospective study examined the developmental changes over time of adolescents diagnosed in toddlerhood with autism spectrum disorder and searched for child characteristics at toddlerhood that predict outcome at adolescence. The study included 65 participants who were divided into low cognitive (developmental quotient [less than] 85; N = 41)…

The effects of using interactive media have been well studied among young children and adolescents but remain understudied for middle childhood (ages 6-12 years). Children and youth of this age comprise much of the pre-adult population that uses digital games and apps. The Every Student Succeeds Act says that states must give students access to…

This study reanalyzes data presented by Ritchie, Bates, and Plomin (2015) who used a cross-lagged monozygotic twin differences design to test whether reading ability caused changes in intelligence. The authors used data from a sample of 1,890 monozygotic twin pairs tested on reading ability and intelligence at five occasions between the ages of 7…

Social-cognitive and emotional factors as well as behavior problems contribute to the social difficulties experienced by many students with or at high risk for emotional and behavioral disorders (EBDs). The way that teachers and peers treat and respond to these students can either mitigate or exacerbate their challenges in establishing and…

'High functioning autism' is a term often used for individuals with autism spectrum disorder without an intellectual disability. Over time, this term has become synonymous with expectations of greater functional skills and better long-term outcomes, despite contradictory clinical observations. This study investigated the relationship between…

Designing instruments for children and youth that result in reliable and valid data requires consideration beyond calculating grade-level equivalence of the text. Very little methodological research has been conducted on the survey response processes of children and youth and there are no comprehensive guidelines informing instrument development…
