We investigated the role of children's conflict monitoring skills in revising an intuitive scientific theory. Children aged 5 to 9 (N = 177; 53% girls, data collected in Germany from 2019-2023) completed computer-based tasks on water displacement, a concept prone to misconceptions. Children predicted which of two objects would displace more water…

Children's foundational mathematical skills are critical for future academic attainment. While home mathematical activities (HMAs) have been proposed to support these skills, the extent to which engaging in them supports mathematical skills remains unclear. This preregistered systematic review and multilevel meta-analysis identified 351 effect…

This study addressed whether combining tinkering with digital storytelling (i.e., narrating and reflecting about experiences to an imagined audience) can engender engineering learning opportunities. Eighty-four families with 5- to 10-year-old (M = 7.69) children (48% female children; 57% White, 11% Asian, 6% Black) watched a video introducing a…

Children's spatial activities and parental spatial talk were measured to examine their associations with variability in preschoolers' spatial skills (N = 113, Mage = 4 years, 4 months; 51% female; 80% White, 11% Black, and 9% other). Parents who reported more diversity in daily spatial activities and used longer spatial talk utterances during a…

This study examined long-term mediating effects of the "smalltalk" parenting intervention on children's effortful control at school age (7.5 years; 2016-2018). In 2010-2012, parents (96% female) of toddlers (N = 1201; aged 12-36 months; 52% female) were randomly assigned to either: standard playgroup, "smalltalk" playgroup…

This study examined whether families' conversational reflections after a STEM (science, technology, engineering, and mathematics)-related experience in a museum promoted learning transfer. 63 children (M = 6.93 years; 30 girls; 57% White, 17.5% Latinx, 8% Asian, 5% African American, 9.5% mixed, 3% missing race/ethnicity) and their parents received…

This study explored the hypothesis that preschoolers' deductive reasoning would be improved by encouraging use of divergent thinking (DT). Children of 4-5 years of age (n = 120) were randomly given DT or neutral control exercises before deductive reasoning problems. To allow a stronger test of the hypothesis, half of the children receiving the DT…

This study examined parent-child math talk within three contexts (formal learning; guided play; unguided play) in order to identify characteristics of activities supporting high-quality math engagement. Seventy-two dyads of parents and 4- and 5-year-olds were observed using a set of toy foods; instructions and materials varied across conditions.…

Poverty-related developmental-risk theories dominate accounts of uneven levels of household functioning and effects on children. But immigrant parents may sustain norms and practices--stemming from heritage culture, selective migration, and social support--that buffer economic exigencies. "Comparable" levels of social-emotional functioning in…

A sample of 398 children was followed up from ages 5 to 12 to investigate the relation between peer group rejection and classroom participation. The participation trajectories of individuals and groups of children who were rejected for differing periods of time were examined both during and after rejection using piecewise growth curve analyses.…

The present experimental research examined whether framing early adolescents' (11- to 12-year-olds) learning activity in terms of the attainment of an extrinsic (i.e., physical attractiveness) versus intrinsic (i.e., health) goal and communicating these different goal contents in an internally controlling versus autonomy-supportive way affect…

Clarifies some of the conditions under which verbal processes facilitate or inhibit learning of visual stimuli. (Author/AJ)

This study attempts to follow the development of an "awareness" of the importance of consistency in a logical system with three elements and one operation. Subjects were 127 male and female students, 9-, 11-, 14-, and 16-years-old. (Author/SDH)

Proposes that humans may have evolved a special sensitivity to certain types of social information during rough-and-tumble play that facilitates social cognition. Describes the cognitive benefits of physical play as providing a break from demanding intellectual tasks and hypothesizes that physical play is related to gender differences in spatial…

A powerful means to understand young children's normative development in context is to examine their everyday activities. The daily activities of 79 children (3 years old) were observed, for 20 hr each, in their usual settings. Children were selected from 4 cultural groups: European American and African American (Greensboro, United States), Luo…
