It is well established that parent-child dyadic synchrony (e.g., mutual emotions, behaviors) can support development across cognitive and socioemotional domains. The advent of simultaneous two-brain "hyperscanning" (i.e., measuring the brain activity of two individuals at the same time) allows further insight into dyadic "neural…

Self-regulation in early childhood, including the ability to regulate one's own thoughts, behaviors, and emotions, are associated with a range of outcomes including academic performance, and social development. Research has extensively examined the effects of mother's parental involvement and parenting experiences, such as parenting stress and…

Children develop and learn within dynamic contexts, yet the simplifying assumptions of common statistical methods often relegate such complexity to unexplained error. This chapter discusses ideas from the dynamic systems literature, which focuses on the interplay within and between components of complex systems, such as individuals and their…

Media use and screen time show both positive and negative effects on child development. Parents' behaviors, perceptions, and regulation of parent and child screen-based device (SBD) use may be critical understudied factors in explaining these mixed effects. We developed the Parent Screen-Based Device Use Survey (PSUS) to assess parental use of…

Background: Both transactional and common etiological models have been proposed as explanations of why externalizing behavior problems (EBP) and internalizing behavior problems (IBP) co-occur in children. Yet little research has empirically evaluated these competing theoretical explanations. We examined whether EBP and IBP are transactionally…

Although there is substantial evidence that socioeconomic status (SES) predicts children's executive function (EF), the mechanisms underlying this association are poorly understood. This study tested the utility of two theories proposed to link SES to children's EF: the family stress model and the family investment model. Data came from the…

Early childhood education programs, and particularly those designed to reduce gaps in school readiness between children in poverty and their more affluent peers, have increasingly addressed children's self-regulatory abilities -- their ability to manage behaviors, emotions, and cognitive processes. Although self-regulation is typically defined in…

Children with developmental delays or disabilities (DD) are at risk for self-regulation difficulties and behaviour problems compared to typically developing children. Intervening early is crucial to prevent long-term adjustment challenges across home and school contexts. Parenting has been identified as a malleable target of intervention for…

This mixed methods study examines the impact of online professional development on preschool teachers' self-efficacy, burnout, and stress. Participating teachers (n = 89) were randomly assigned into four groups: one of three treatment conditions (course-only, conference, reflective writing) or a control group. All treatment conditions received a…

Children growing up in adversity are well known to be at risk of educational failure. Recent advances in neuroscience indicate that the nature of the caregiving environment in the first weeks and months of life influences the neural architecture of the developing brain, via epigenetic processes. Neglectful caregiving is hypothesised to contribute…

Many kindergarten teachers have encountered children who enter school lacking the ability to control their behavior, but they may not understand the social and biological processes behind these children's disruptive behavior. The author reviews research into early childhood brain development to explain how trauma and chronic stress can make it…

This article synthesizes foundational knowledge from multiple scientific disciplines regarding how humans develop in context. Major constructs that define human development are integrated into a developmental system framework, this includes--epigenetics, neural malleability and plasticity, integrated complex skill development and learning, human…

Research Findings: Addressing factors that influence children's self-regulation is a critical step toward closing achievement gaps that have consistently been found for African American and Latino children as well as children living in poverty. Cumulative sociodemographic risk in childhood is now widely understood to be a developmental risk factor…

Early caregiving experiences play a central role in shaping emotional development, stress physiology, and refinement of limbic circuitry. Converging evidence across species delineates a sensitive period of heightened neuroplasticity when frontoamygdala circuitry is especially amenable to caregiver inputs early in life. During this period, parental…

Parental sensitivity and nurturance are important mechanisms for establishing biological, emotional, and social functioning in childhood. Sensitive, nurturing care is most critical during the first three years of life, when attachment relationships form and parental care shapes foundational neural and physiological systems, with lifelong…
