Recent research has highlighted the critical role in children's cognitive development of the metacognitive support parents give their children during everyday interactions. Our main goal was to examine whether parents made consistent use of metacognitive talk across different parent - child interaction contexts and to document the effect of this…

The aim of this study was to examine genetic variations underlying the early neurodevelopmental outcome of developmental disabilities (DDs). The study cohort consisted of 191 children with DDs. Diagnosis was assessed at baseline and at the index age (72-84 months). Exome sequencing was conducted and putative risk variants were identified.…

Adverse experiences throughout development confer risk for a multitude of negative long-term outcomes, but the processes via which these experiences are neurobiologically embedded are still unclear. Adolescence provides an opportunity to understand how these experiences impact the brain's rapidly changing structure. Two models are central to…

The aim of this study is to compare the neurological status, developmental parameters and physical fitness of children who engage in regular physical activity in the preschool period versus those who do not. The study included 305 healthy children aged 4-6 years, consisting of 154 girls and 151 boys. In addition to evaluating the demographic…

The concept of intellectual need, which proposes that learning is the result of students wrestling with a problem that is unsolvable by their current knowledge, has been used in instructional design for many years. However, prior research has not described a way to empirically determine whether, and to what extent, students experience intellectual…

Background: Children with Prader-Willi Syndrome (PWS) display impaired pretend play abilities, reflective of broader social-cognitive challenges. Pretend play interventions for children with PWS demonstrate preliminary efficacy for improving cognitive and affective processes in play. It is unknown which specific intervention strategies, such as…

It is a very important step to consider the variables that affect sibling relationships together. This study aimed to determine the effects of the variables Birth Order (First, Middle, and Last), Gender (Female, Male), and Number of Siblings ("two or three" and "four or more"), which have been suggested to affect sibling…

Embodied cognition--the idea that mental states and processes should be understood in relation to one's bodily constitution and interactions with the world--remains a controversial topic within cognitive science. Recently, however, increasing interest in predictive processing theories among proponents and critics of embodiment alike has raised…

Need for cognition is conceptualized as an individual's intrinsic motivation to engage in and enjoy effortful cognitive activities. Over the past three decades, there has been increasing interest in how need for cognition impacts and correlates with learning performance. This meta-analysis summarized 136 independent effect sizes (N = 53,258) for…

Evaluating evidence and restructuring beliefs based on anomalous evidence are fundamental aspects of scientific reasoning. These skills can be challenging for both children and adults, especially in domains where they possess inaccurate prior beliefs that can interfere with the acquisition of correct scientific information (e.g., heavier objects…

Early experiences in STEM education can contribute to positive cognitive development in young children. When students have the opportunities to play, inquire, follow their interests/curiosities, develop STEM identities, be creative, and operate within concrete/contextualized STEM explorations, they will experience expansive cognitive growth.…

Children are limited in visual search accuracy and this ability increases from childhood to adolescence. Developmental limitations in visual search could be related to children's difficulties in efficiently planning and executing their search, often assessed with cancellation tasks. However, few studies have examined age-related changes in visual…

In many cultural contexts, judging another as conscious or not has profound practical, legal, and philosophical consequences. However, little research focuses on how our ability to make such judgements arises. Thirty years ago a classic set of studies by Flavell et al. demonstrated that children do not develop a complex understanding of conscious…

In an increasingly complex world, the development of logical reasoning skills is vital for students of all ages. This study investigates the impact of the Logical Intelligence Enhancement Program (LIEP) on the logical reasoning skills of a large sample of primary school students aged between eight and eleven. The research encompasses 54 classes…

In some contexts (e.g., legal and medical), it is imperative that children indicate when they do not understand an adult's question. Yet, little research has examined children's clarification requests. We asked 122 4- to 9-year-olds tricky and simple interview questions to assess how often and how children request clarification in interviews, the…
