Language development is an important facet of early life. Deaf children may have exposure to various languages and communication modalities, including spoken and visual. Previous research has documented the rate of growth of English skills among young deaf children, but no studies have investigated the rate of ASL acquisition. The current paper…

Background: Computational thinking (CT) has emerged as a critical component of 21st-century skills, and increasing effort was seen in exploring the development of CT skills in K-12 students. Despite cumulative research on exploring students' CT acquisition and its influencing factors, learners' development of the skill over time and the underlying…

According to previous findings, math anxiety already occurs at early school age and is negatively correlated with math achievement. So far, however, little is known about the nature of math anxiety in young children. To fill this gap, we present the results of a longitudinal study on the math anxiety of children that were followed in the first…

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…

Multifinality, equifinality, and fanning are important developmental concepts that emphasize understanding interindividual variability in trajectories over time. However, each concept implies that there are points in a developmental window where interindividual variability is more limited. We illustrate the multifinality concept under…

The systematic literature review is based on a critical need in the area of values, where there are many uncertainties around universal definitions and drivers of values and traits. The study evaluated definitions, categories, drivers and the interdependence between values and personality traits and behaviours. Over 5,873 studies over a 70-year…

Recent genetic discoveries offer a new lens through which to study cognitive, emotional, behavioral, and social processes that are foundational to children's development. In this article, we review the latest advances in genomics--genome-wide association studies and the polygenic scores that have come out of them--and discuss how these techniques…

Background: Although research clearly demonstrates the importance of motivation in mathematics learning, relatively little is known about the developmental dynamics between different facets of mathematics motivation and performance, especially in the early years of schooling. Aims: In a longitudinal setting, we examined (1) how children's ability…

By approximately 6 years of age, children can use time-based visual selection to ignore stationary stimuli, already in the visual field and prioritize the selection of newly arriving stimuli. This ability can be studied using preview search, a version of the visual search paradigm with an added temporal component, in which one set of distractors…

The goal of this intensive longitudinal study was to trace the developmental trajectories of infant pointing production, through consideration of the modality (i.e. pointing alone vs pointing-vocal coupling) and the communicative intention (i.e. imperative vs declarative). Multilevel analysis was used to model the normative trend and the…

Empathy and executive functions (EFs) are multimodal constructs that enable individuals to cope with their environment. Both abilities develop throughout childhood and are known to contribute to social behavior and academic performance in young adolescents. Notably, mentalizing and EF activate shared frontotemporal brain areas, which in previous…

Individuals of the same species display remarkable variation in behavior, even in identical contexts. Increasing complexity in behavioral phenotypes brings with it an increase in individual variation in the manifestation of those phenotypes, and human behavior undoubtedly stands at the pinnacle of complexity. In this article, we discuss current…

Purpose: We evaluated whether naive listeners' ratings of the gender typicality of the speech of children assigned male at birth (AMAB) and children assigned female at birth (AFAB) were different at two time points: one at which children were 2.5-3.5 years old and one when they were 4.5-5.5 years old. We also examined whether measures of speech,…

There is general agreement that humans represent numerical, spatial, and temporal magnitudes from early in development. However, there is disagreement about whether different magnitudes converge within a general magnitude system and whether this system supports behavioral demonstrations of cross-magnitude interactions at different developmental…

Executive function (EF) is a key cognitive process that emerges in early childhood and facilitates children's ability to control their own behavior. Individual differences in EF skills early in life are predictive of quality-of-life outcomes 30 years later (Moffitt et al., 2011). What changes in the brain give rise to this critical cognitive…
