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…

The present study examines variation in the effect of birth weight on children's early cognitive and socioemotional outcomes by family socioeconomic status (SES). It is hypothesized that not only will lower birth weight children display worse cognitive and socioemotional outcomes prior to school entry, as prior research has found, but that effects…

Previous research on Montessori preschool education is inconsistent and prone to analytic flexibility. In this preregistered study, disadvantaged preschoolers in a French public school were randomly assigned to either conventional or Montessori classrooms, with the latter being adapted to French public education. Adaptations included fewer…

Economic difficulties in early childhood are associated with significant adverse long-term socioemotional and cognitive outcomes. In this study, we examine an understudied financial stressor that is often observed during periods of high unemployment--transient familial financial stress (TFS). We use the early childhood longitudinal study--(birth)…

Background: Several studies show that socio-economic status (SES) is related to the developmental trajectories of children with typical development (TD). However, few studies have analysed this relationship regarding children with neurodevelopmental disorders such as Down syndrome (DS). In this paper, we analyse the impact of SES in the…

Publicly funded center-based preschool programs were designed to enhance low-income children's early cognitive and social-emotional skills in preparation for kindergarten. In the U.S., the federal Head Start program and state-funded public school-based pre-kindergarten (pre-k) programs are the two primary center-based settings in which low-income…

Purpose: This study investigates false belief (FB) understanding in children who are hard of hearing (CHH) compared with children with normal hearing (CNH) at ages 5 and 6 years and at 2nd grade. Research with this population has theoretical significance, given that the early auditory-linguistic experiences of CHH are less restricted compared with…

The present study examined the interplay among negative emotionality, responsive parenting and socio-cognitive developmental outcomes (i.e., communication, personal-social and problem-solving outcomes) in about 1620 Korean children using three waves of longitudinal data spanning the first 2 years of their life. Results from the Structural Equation…

This paper assesses the impact of welfare reform's parental work requirements on low-income children's cognitive and social-emotional development. The identification strategy exploits an important feature of the work requirement rules--namely, age-of-youngest-child exemptions--as a source of quasi-experimental variation in first-year maternal…

Research Findings: Although there has been considerable research on the associations between the qualifications of teachers in center-based settings and preschool-age children's developmental outcomes, very little is known about the relationships between home provider qualifications and the developmental outcomes of toddlers who attend licensed…

This longitudinal study investigates the differences in cognitive and socio-emotional development and academic achievement between children educated in special education classes (N = 37) and regular classes (N = 37). The study is retrospective. The first measurement point was while children were attending play-oriented kindergarten and no decision…

Theories of social-cognitive development have attributed a foundational role to declarative joint attention. The present longitudinal study of 83 children, who were assessed on a battery of social-cognitive tasks at multiple measurement points from the age of 12 to 50 months, tested a predictive model of theory of mind (false-belief…

The purpose of this study was to systematically review the literature to identify school-related outcomes associated with trauma in school-aged youth. The sample of articles (n = 83) included data on school-aged youth (pre-kindergarten to grade 12) who were 18 years or younger. Cognitive, academic, and teacher reported social-emotional-behavioral…

The current longitudinal study examined the role of cumulative social risk on children's theory of mind (ToM) and executive functioning (EF) across early development. Further, we also tested a cascade model of development in which children's social cognition at 18 months was hypothesized to predict ToM and EF at age 4.5 through intermediary…

Adolescents become increasingly sensitive to social evaluation. Some previous studies have related this change to pubertal development. The present longitudinal study examined the role of sociocognitive development. We investigated whether or not the transition to recursive thinking, the ability to think about (others') thoughts, would be…
