There are contentious and persistent gender differences reported in some measures of spatial skills, particularly mental rotation and, to a lesser extent, perspective-taking, which may have an impact on mathematics success. Furthermore, pathways between spatial skills and mathematics may be mediated by other cognitive factors, such as fluid…

There are long-held concerns regarding the impact of screen media on children's cognitive development. In particular, fast pace and fantastical events have been theorized to deplete children's cognitive resources, leading to reductions in their attention and executive functions (EF). To date, however, empirical tests of short-term effects of media…

Children experience a variety of messages about racial-ethnic socialization from their parents, teachers, and other sources, who might not answer children's questions about race, or might explicitly promote the idea that race does not matter. However, how such messages affect children's reasoning about disparities, including whether children…

It is unknown how the brain supports reading development in individuals with reading disability (RD). In a cross-sectional study (i.e., children, adolescents, adults), we found an age-related shift in brain activation from posterior to anterior part of the left occipitotemporal (OT) area in typical readers, supporting orthographic specialization,…

Current understanding of how culture relates to the development of children's gender-related peer preferences is limited. To investigate the role of societal acceptance of gender nonconformity, this study compared children from China and Thailand. Unlike China and other cultures where the conceptualization of gender as binary is broadly accepted,…

Adults remember items with shared contexts as occurring closer in time to one another than those associated with different contexts, even when their objective temporal distance is fixed. Such temporal memory biases are thought to reflect within-event integration and between-event differentiation processes that organize events according to their…

We explored the causal role of individual and age-related differences in working memory (WM) capacity in long-term memory (LTM) retrieval. Our sample of 160 participants included 120 children (6-13-years old) and 40 young adults (18-24 years). Participants performed a WM task with images of unique everyday items, presented at varying set sizes.…

Relatively little work has focused on why we are motivated to learn words. In adults, recent experiments have shown that intrinsic reward signals accompany successful word learning from context. In addition, the experience of reward facilitated long-term memory for words. In adolescence, developmental changes are seen in reward and motivation…

While day-to-day negative affect normatively rises across adolescence, emotional experiences also stratify, or diverge, across individuals. Moreover, negative affect is not a unitary construct but comprises distinct feeling states (e.g., sadness, anger, anxiety), each characterized by distinct age-related trends. Yet, most developmental research…

We studied the role of sensorimotor and working memory systems in supporting development of perceptual rhythm processing with 119 participants aged 7-12 years. Children were assessed for their abilities in sensorimotor synchronization (SMS; beat tapping), auditory working memory (AWM; digit span), and rhythm discrimination (RD; same/different…

Recent evidence suggests that deaf children with CIs exposed to nonnative sign language from hearing parents can attain age-appropriate vocabularies in both sign and spoken language. It remains to be explored whether deaf children with CIs who are exposed to early nonnative sign language, but only up to implantation, also benefit from this input…

Sound symbolism refers to associations between language sounds and certain perceptual or semantic properties. One well-studied example is the maluma/takete effect, in which individuals tend to associate round-sounding nonwords like maluma with round shapes, and spiky-sounding nonwords like takete with spiky shapes. This phenomenon suggests that…

Children can acquire novel word meanings by using pragmatic cues. However, previous literature has frequently focused on in-the-moment word-to-meaning mappings, not delayed retention of novel vocabulary. Here, we examine how children use pragmatics as they learn and retain novel words. Thirty-three younger children (mean age: 5.0, range: 4.0-6.0,…

Previous cross-cultural research has described two different attention styles: a holistic style, characterized by context-sensitive processing, generally associated with interdependent cultural contexts, and an analytic style, a higher focus on salient objects, generally found in independent cultural contexts. Though a general assumption in the…

Although exploratory play is considered a hallmark of cognitive development and learning, relatively few studies have been able to quantitatively characterize the shifts that may occur in children's approach to exploration. One reason for this gap is due to challenges coding and analyzing children's exploratory play behavior. In our paper, we…
