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…

The human capacity for rational decisions hinges on modal judgment: the discernment of what could, has to, or cannot happen. This ability was proposed to be a late outcome of human cognitive development, contingent on the mastery of linguistic structures. Here, we show that preschool-age children are capable of sophisticated forms of modal…

The study of how children learn numbers has yielded one of the most productive research programs in cognitive development, spanning empirical and computational methods, as well as nativist and empiricist philosophies. This paper provides a tutorial on how to think computationally about learning models in a domain like number, where learners take…

Counterfactual emotions such as regret may aid future decision-making by encouraging people to focus on controllable features of personal past events. However, it remains unclear when children begin to preferentially focus on controllable features of such events. Across two studies, Australian 4-9-year-olds (N = 336, 168 females; data collected…

Aperiodic electroencephalography (EEG) activity is hypothesized to index biological mechanisms that underpin brain functioning. This longitudinal study characterized the developmental trajectories of the aperiodic slope (i.e., aperiodic exponent) and offset from infancy to 7 years of age in a US community sample (N = 391, 46.5% female,…

Working memory (WM) is a critical cognitive system that supports processing a variety of information. Remembering different types of objects may impose different levels of cognitive demands on WM performance. In the present study, we examined 205 children's WM in representing different types of content and its developmental trajectories in early…

Unlike adults, young children think that many weird and unlikely events are impossible. Existing theories have argued that this developmental shift is driven primarily by age-related changes in knowledge as well as an increasing ability to reflect on one's modal intuitions. However, this intuition + reflection model fails to explain…

Executive functions (EF) are crucial to regulating learning and are predictors of emerging mathematics. However, interventions that leverage EF to improve mathematics remain poorly understood. 193 four-year-olds (mean age = 3 years; 11 months pre-intervention; 111 female, 69% White) were assessed 5 months apart, with 103 children randomised to an…

Children often say that possible events are impossible, and only gradually come to see these events as possible. For instance, they often deny that people could do unusual things, like own a pet peacock, or immoral things, like stealing or lying. These possibility denials are surprising. For instance, children have first-hand experience with the…

Conversational turns are an important predictor of cognitive and language development, but little is known about their relationship with socioemotional development. In a previous study using LENA technology, Gómez and Strasser (2021) found that conversational turns assessed with 43 infants at 18 months predicted socioemotional competencies at 30…

This longitudinal study investigates metacognitive development in children aged four to six (N = 148; 74 girls; 106 White, 21 multiracial, 17 Black, 3 Asian, 1 Latino; collected in 2017-2019) compared to adults (N = 26, 13 women; collected in 2022). We assessed metacognitive monitoring and control using experimenter-elicited and self-generated…

Montessorians, with their long history of careful attention to children's developmental possibilities, can and should develop materials and pedagogical methods that can help children not merely use but master the technologies of the future. This does not mean putting a computer in the hands of every 3-year-old; quite the contrary. Rather, it means…

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.…

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…

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.…
