Touchscreen devices differ from passive screen media in promoting physical interaction with events on the screen. Two studies examined how young children’s screen-directed actions related to self-regulation (Study 1) and word learning (Study 2). In Study 1, 30 2-year-old children’s tapping behaviors during game play were related to their self-regulation, measured using Carlson’s snack task: girls and children with high self-regulation tapped significantly less during instruction portions of an app (including object labeling events) than did boys and children with low self-regulation. Older preschoolers (N = 47, aged 4–6 years) tapped significantly less during instruction than 2-year-olds did. Study 2 explored whether the particular way in which 170 children (2–4 years of age) interacted with a touchscreen app affected their learning of novel object labels. Conditions in which children tapped or dragged a named object to move it across the screen required different amounts of effort and focus, compared to a non-interactive (watching) condition. Age by sex interactions revealed a particular benefit of dragging (a motorically challenging behavior) for preschool girls’ learning compared to that of boys, especially for girls older than age 2. Boys benefited more from watching than dragging. Children from low socioeconomic status families learned more object names when dragging objects versus tapping them, possibly because tapping is a prepotent response that does not require thoughtful attention. Parents and industry experts should consider age, sex, self-regulation, and the physical requirements of children’s engagement with touchscreens when designing and using educational content.

Undergraduates’ distress has increased dramatically since the COVID-19 pandemic’s onset, raising concerns for academic achievement. Yet little is known about the mechanisms by which pandemic-related distress may affect students’ learning and performance, and consequently, how we might intervene to promote student achievement despite the continuing crisis. Across two studies with nearly 700 undergraduates, we highlight the mediating role of distraction: undergraduates higher in COVID-19 distress saw lower learning gains from an asynchronous neuroscience lesson due to increased mind wandering during the lesson. We replicate and extend this finding in Study 2: probing what pandemic-related stressors worried students and revealing systematic differences among students of marginalized identities, with largest impacts on first-generation, Latinx women. We also examined whether stress reappraisal or mindfulness practices may mitigate the observed distress-to-distraction pathway. Only mindfulness reduced mind wandering, though this did not translate to learning. We conclude with implications for practice and future research.

Gender gaps in mathematics achievement persist in many contexts and when visible, these gaps are paradoxical. Low-stakes measures of mathematics achievement such as grades and study behaviors favor girls, while gaps tend to reverse on assessments/competitions. We explore whether different impacts of raising performance stakes could be one explanation. Study 1 experimentally manipulated the stakes by imposing a performance-contingent, social-evaluative pressure either: before instruction (n = 66), before testing (n = 61), or none (n = 54). Pressure, particularly when experienced during instruction, reduced learning among girls. In contrast, boys trended toward enhanced learning under pressure. In the absence of pressure, girls exhibited strikingly larger gains in learning. Study 2 drew from a larger dataset (n = 386) to interrogate whether girls' superior learning in the no-pressure context might simply be an artifact of differences in prior knowledge, cognitive resources, or demographic variables, but the effect replicated and was not explained by these factors.Men and women do not differ meaningfully in mathematics aptitude (see Spelke, 2005
