The development of executive function (EF) has been linked to various life outcomes, motivating intense research on the topic. While much of this research has focused on more thoroughly understanding age-related changes of the underlying neurocognitive mechanisms involved, recent theoretical and empirical works have stressed how the immediate…

While much work has emphasized the role of the environment in language learning, research equally reports consistent effects of the child's knowledge, in particular, the words known to individual children, in steering further lexical development. Much of this work is based on cross-sectional data, assuming that the words typically known to…

Creative thinking is critical to overcome many daily life situations. As such, there has been a growing interest on how creative thinking develops during childhood. However, little is known about the underlying mechanisms driving its development. Indeed, almost all research has focused on divergent thinking, leaving aside convergent thinking, and…

Cognitive tasks are seldom evaluated on their ability to provide valid and reliable measurements of the construct they intend to measure. This scarcity of psychometric evaluations makes it challenging to evaluate replications of experimental effects and to relate performance in cognitive tasks to other constructs of interest. In developmental…

The ability to prioritize remembering explicitly valuable information is termed value-based remembering. Critically, the processes and contexts that support the development of value-based remembering are largely unknown. The present study examined the effects of feedback and metacognitive differences on value-based remembering in predominantly…

On a daily basis, children make decisions about how to negotiate their physical environment. Sometimes they engage in physical tasks that involve risk, requiring them to judge the safety of how to negotiate the environment safely. Individual differences in children's age, sex, physical size, and personality may impact those decisions. We used…

Although we cannot see or touch time, across many cultures, we use spatial representations to think about this abstract concept. Spatial representations of time are thought to support temporal concepts that might otherwise be difficult to represent and reason about, such as the temporal component of episodic memory. One common form of spatially…

Students' experiences of physical education (PE) are considered important for lifelong attitudes towards physical activity. Sex-related differences and the individualised tempo in anthropometric growth because of biological maturation lead to secondary school students within chronological age-ordered classes possessing vast differences in…

This empirical tracking case study explores the content and quality of an infant's home musical environment and family member-infant musical interactions. To this end, this study tracked and analyzed audio recordings of an infant girl's family life between the ages of seven and thirteen months and follow-up interviews with her parents. The…

Arithmetic ability is critical for daily life, academic achievement, career development, and future economic success. Individual differences in arithmetic skills among children and adolescents are related to variations in brain structures. Most existing studies have used hypothesis-driven region of interest analysis. To identify distributed brain…

In this report, we perform a descriptive analysis of kindergarten readiness in Illinois. We use data on the population of Illinois kindergarteners between the 2017-18 and 2021-22 school years provided by the Illinois State Board of Education (ISBE). In our analysis, we build on the existing literature and examine readiness over time, by domain,…

The choice of cortisol sampling times in early childhood studies varies widely. Given that recommendations on sampling protocols are largely based on adults, the present study aimed to broaden current knowledge by examining how reliably cortisol measures obtained at different daytimes would reveal between-individual differences in toddlers'…

Many young people are inclined toward risk taking and also toward helping other people. "Prosocial risk taking" is a term that can describe different ways that youth provide significant instrumental and emotional support to family members, friends, and strangers, even when it involves a personal risk. In this article, we review research…

The present study used a novel, well-controlled paradigm to investigate the development of cool, hot-positive, and hot-negative inhibitory control in a sample of children (6- to 11-year-old; N = 38, 21 females), adolescents (12- to 18-year-old; N = 38, 24 females), and adults (19- to 38-year-old; N = 38, 28 females; sample location: United…

It is widely accepted that investing in early childhood helps build the foundations of a healthy, productive, and equitable society. Guided by that knowledge, a range of broad-based programs and targeted services make a significant difference for millions of children, yet a closer look at outcome data shows that some benefit greatly, some benefit…
