Objective: To examine associations between cognitive stimulation in the home at 6 months and maternal feeding styles at 24 months, direct intervention effects of Smart Beginnings (SB) on feeding styles, and potential indirect effects of SB on feeding styles via earlier intervention effects on cognitive stimulation. Methods: Single-blind, two-site…

Purpose: This case series documents developmental changes over time and in response to a novel intervention, Sitting Together and Reaching to Play (START-Play), in children with early-life seizures. Methods: Thirteen children with early-life seizures were included from a subset of participants in the START-Play multisite, randomized controlled…

Kim and Opfer (2017) found that number-line estimates increased approximately logarithmically with number when an upper bound (e.g., 100 or 1000) was explicitly marked (bounded condition) and when no upper bound was marked (unbounded condition). Using procedural suggestions from Cohen and Ray (2020), we examined whether this logarithmicity might…

The present study examines the link between children's number of older siblings and their cognitive development, as measured by executive function (EFs) skills and verbal skills (VIQ) in a sample of 1,302 4-year-old children (54% boys) living in rural Pakistan. Specifically, we investigate whether the links between the number of older siblings and…

This study aimed to explore whether early developmental abilities are related to future executive function (EF) in children with motor delays. Fourteen children with motor delays (Mean age = 10.76, SD = 2.55) were included from a larger study. Object interaction and developmental outcomes (Bayley-III) were evaluated at baseline and 3, 6, and 12…

Background: Student academic behavioral engagement (BE) contributes to learning and school success. Student-teacher relationships (STRs) may promote BE, although previous findings regarding how these constructs are associated over time are mixed. For young autistic students who face barriers to early school success, a high-quality STR may serve as…

Children's understanding of death has been a topic of interest to researchers investigating the development of children's thinking and clinicians focusing on children's coping with the death of a loved one. Traditionally, researchers in cognitive development have mainly focused on death from a biological perspective. Current research suggests that…

Although there is a rich literature on children's strategies for remembering, little attention has been paid to characterizing developmental change within individual children and to examining mediators that may bring about such change. To address these issues, we assess children's memory skills over time while simultaneously examining…

Aims: Children with neuromotor delays are at risk for reaching and object exploration impairments, which may negatively affect their cognitive development and daily activity performance. This study evaluated the effectiveness of the Sitting Together And Reaching To Play (START-Play) intervention on reaching-related exploratory behaviors in…

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…

Exergames (video games that promote cognitive and physical activity simultaneously) benefit executive function (EF) in elderly populations. It has been suggested that exergames may induce larger effects than cognitive or exercise training alone, but few reviews have synthesized the causal factors of exergames on EF from experimental research with…

Parental engagement in stimulating activities and support in both formal and informal learning environments are important for early childhood development. However, little is known about how parental mental health and beliefs about early childhood development shape such investments. We draw on a sample of young children and their primary caregiver…

The current paper investigates the structural validity of the Children's Concentration and Empathy Scale (CCES), which was designed based on Montessori's developmental theory to assess, using teacher ratings, the coherence of attention-related characteristics (concentration, empathy, and normalization) in children from 1.5 to 12 years old. The…

It is often argued that metacognition includes 2 components: monitoring and control. However, it is unclear whether these components can operate independently, or whether they always operate as part of a hierarchy. The current study attempts to address this issue. In Experiment 1 (N 90), age-related differences were assessed to examine the…

In this article, we report on a three-pronged effort to create a hypothetical learning progression for quantification in science. First, we drew from history and philosophy of science to define the quantification competency and develop hypothetical levels of the learning progression. More specifically, the quantification competency refers to the…
