Interpersonal synchronization between infants and parents emerges early in life and serves as a critical foundation for the development of cognitive, social, and communicative abilities. Traditionally, researchers have assessed this synchrony using composite scores that capture the overall degree of reciprocal, coordinated interaction within a…

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,…

Fine motor skills (FMS) have been intensely studied in developmental contexts, with little attention to their empirical structure and developmental changes. We tested the factor structure of FMS on 5- to 10 year old children in two cohorts from 2020 to 2023, beginning in kindergarten and grade 2 and followed up 1 year later (n = 240 and 310, 49.7%…

Australian children aged 6-9 years (N = 120, 71 females; data collected in 2021-2022) were tasked with remembering the locations of 1, 3, 5, and 7 targets hidden under 25 cups on different trials. In the critical test phase, children were provided with a limited number of tokens to allocate across trials, which they could use to mark target…

Within educational research, there is a growing interest in using neuroscience methods such as electroencephalography (EEG) and event-related potentials (ERPs) to probe neural mechanisms underlying students' learning and development, in natural, school-based settings. The results of these studies are beginning to appear in educational,…

Educational neuroscience was born out of the promise that brain imaging would generate discoveries that change how we educate our children. Many neuroscientists and educators alike feel that this promise has not been fulfilled and have begun to question the utility of this nascent field that is arising at the intersection of two well-established…

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…

As young as 3 years old, children rely on a mutual intentionality framework to confer group membership--that is, agreement between a joiner ("I want to be in your group") and group ("We want you to be in our group"). Here, we tested whether children apply this cognitive framework in the context of identity-based groups,…

Enhancing executive function in children and adolescents can have significant positive impact on their current and future daily lives. Upregulation of executive function associated with motor skill acquisition suggests that motor learning scenarios provide valuable developmental opportunities to optimize executive function. The present systematic…

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…

Theory of mind (ToM) is the ability to attribute mental states and feelings to others, and to understand that those mental states and feelings affect their behaviour. It is one of three core developmental tasks for children in preschool years, along with emotion self-regulation and relationships with parents and family members. Given there are…

Studies in low-resource settings suggest that multiple aspects of early childhood development are sensitive to the relative poverty of a child's environment. We examined whether direct, quantitative measures of early developing cognitive functions show a similar association with relative poverty. Eye movement latencies were recorded in children at…

The proposed study sought to investigate whether maternal experiences of racial discrimination and gendered racial stress are associated with offspring executive functioning. Total 266 Black mother-child pairs in the United States were assessed from pregnancy through child age of 4 years. We hypothesized that children whose mothers reported higher…

Story-time serves as an interactive linguistic tool through which parents encourage their children to share narratives. Grounded in sociocultural and narrative theories, this study employed a visual ethnographic approach to explore how parents perceive and engage in story-time interactions within 33 Chinese families. Data were collected through…

This paper reports on the findings of a natural experiment based on a sample of 1123 children aged 4-8 from the provinces of Punjab in Pakistan, and Gujarat in India. It looks at the impact of attendance (or not) in early schooling on the cognitive and social-emotional development of young children. The role of school attendance was assessed over…
