Successful active learning has often been quantified with respect to either the efficiency of information search or the accuracy of subsequent recall. In this article, we explored the hypothesis that children's memory is influenced by the types of information search strategies they implement, which may emphasize different aspects of the task…

While there is considerable evidence that children's early ability to understand others' mental states, called "theory of mind," is shaped by family experiences, it remains unclear whether children's social interactions at school influence theory of mind (ToM) beyond early childhood. We tested whether the mean level…

Evaluating evidence and restructuring beliefs based on anomalous evidence are fundamental aspects of scientific reasoning. These skills can be challenging for both children and adults, especially in domains where they possess inaccurate prior beliefs that can interfere with the acquisition of correct scientific information (e.g., heavier objects…

A foundational mechanism underlying human cooperation is reciprocity. In the context of repeated interactions with others, it is not always clear the degree to which in-kind responses reflect responsiveness to partners' prior behaviors ("reactive" responses), an interest unrelated to the partner ("nonreactive" responses), or…

Infants' preference for vowelharmony (VH, a phonotactic constraint that requires vowels in a word to be featurally similar) is thought to be language-specific: Monolingual infants learning VH languages show a listening preference for VH patterns by 6 months of age, while those learning non-VH languages do not (Gonzalez-Gomez et al., 2019; Van…

Gender-stereotyped beliefs develop early in childhood and are thought to increase with age based on prior research that was primarily carried out in Western cultures. Little research, however, has examined cross-cultural (in)consistencies in the developmental trajectory of gender-stereotyped beliefs. The present study examined implicit gender-toy…

The study investigated age-related trends in moral identity goal characteristics, as proposed in previous research (Krettenauer, 2022a), by modifying the Self-Importance of Moral Identity Questionnaire (Aquino & Reed, 2002). Internally and externally motivated moral identity was assessed on varying levels of abstractness for promotion…

This randomized controlled trial explored the effects of parental reminiscing training on preschoolers' memory and metacognition among French-speaking White parents and their typically developing children (24 females, 20 males; M[subscript months] = 49.64) in Belgium. Participants were assigned, with age stratification, to the immediate…

During infancy and toddlerhood, parents show large individual differences in the extent to which they are able to tailor their parenting behaviors to their children's swiftly changing developmental needs. The first aim of our study was, therefore, to distinguish parenting profiles at three time points during infancy and toddlerhood (i.e., 5, 10,…

In putatively meritocratic societies, doing well in school is a pivotal precondition for accessing further and higher education, which, in turn, has a pervasive, long-term influence on adulthood development. Yet, doing well in school may also predict "real-life success" outside formal education settings and independent of the educational…

Children show less positivity toward gender-nonconforming (GN) than gender-conforming (GC) peers. Yet, little is known about children's reasoning about peers of varying gender expressions, including age-, gender-, and culture-related influences. We investigated how children aged 4- to 5- and 8- to 9-years-old in Hong Kong and Canada (N = 678)…

This study examines the moment-to-moment within-person associations between maternal and child behaviors during a challenging puzzle task and compares these associations between mother--child dyads from the United States (n = 99, 52 boys, M[subscript child age] = 56.05 months, SD = 6.44) and China (n = 101, 46 boys, M[subscript child age] = 57.41…

The human capacity for technological innovation and creative problem-solving far surpasses that of any species but develops quite late. Prior work has typically presented children with problems requiring a single solution, a limited number of resources, and a limited amount of time. Such tasks do not allow children to utilize one of their…

Can well-documented gender differences in evaluations of prosocial versus antisocial actions found in childhood and adulthood be traced to sex differences in basic sociomoral preferences in infancy? We provide an answer to this question by meta-analyzing sex differences in preference for prosocial over antisocial agents in a set of 53 samples of…

Process praise (i.e., praise for effort) facilitates childhood persistence. However, less is known about the mechanism by which process praise influences persistence in infancy. Here, we propose that well-timed process praise reinforces the link between effort and success, thus promoting persistence in young children. In Experiment 1, U.S. infants…
