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…

Pretend play is one of the most beneficial and complex forms of play that promotes a myriad of children's development. Children's engagement in pretend play can be influenced by their genders, age, material or toys available, and adults' support. Pretend play has been long studied globally, however, there is still a dearth of available information…

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,…

Language development plays a pivotal role in a child's cognitive and overall growth, progressing through identifiable stages that ultimately lead to adult communication. It serves as a significant indicator of a child's intellectual and overall development. This study aims to explore the impact of daily technology use on children's language…

Effective communication is a fundamental aspect of children's daily living, enabling interaction with adults and peers. A rich literature suggests that communicative abilities develop with age, while little is known about cross-cultural differences and similarities. This study presents a comparison of the communicative performance of Finnish (n =…

The psychological mechanisms that subserve inductions about novel social categories in childhood are hotly debated. While research demonstrated that language, and in particular generic statements, plays a major role in how children learn to attribute properties to social categories, developmental theories propose other mechanisms. One theoretical…

The extent to which Theory of Mind (ToM) performance is influenced by cultural and gender differences remains a subject of debate. A sample of 324 Dutch and 511 Italian children (52% boys; 2.8-11.7 years; 50% boys; 2.6-10.3 years; respectively) was administered the ToM Storybooks. Analysis focused on indicators of nonlinearity: moving standard…

Across all cultures, parents have intuitive ideas ("ethnotheories") of what undesirable child characteristics are as well as how to explain them. Yet there have been relatively few cross-cultural comparisons of parents' ethnotheories about the nature and causes of child misbehavior. 108 mothers of 5-year-old children from the United…

The present study used a novel, well-controlled paradigm to investigate the development of cool, hot-positive, and hot-negative inhibitory control in a sample of children (6- to 11-year-old; N = 38, 21 females), adolescents (12- to 18-year-old; N = 38, 24 females), and adults (19- to 38-year-old; N = 38, 28 females; sample location: United…

Extensive research demonstrates the far-reaching impacts of early childhood development (ECD) interventions, including both pre-primary education (PPE) and in-home nurturing. At the same time, a limited understanding of inequalities in ECD exposure across groups of children in many countries poses a fundamental challenge to effective policymaking.…

Our interest is in the development of gratitude as a moral virtue, and its variability across different cultural contexts. Given psychology's overreliance on samples collected from the United Sates, Western Europe, and Australasia, we contrasted patterns of age-related expressions of gratitude among a sample of U.S. 7- to 14-year-old children with…

Background: Although research clearly demonstrates the importance of motivation in mathematics learning, relatively little is known about the developmental dynamics between different facets of mathematics motivation and performance, especially in the early years of schooling. Aims: In a longitudinal setting, we examined (1) how children's ability…

Background: Play is a main driver of children's cognitive and social development and is crucial for educational success ("Paediatrics," 119, 2007 and 182). In recent years, however, parents and schools are under pressure to prioritize academic targets over play. Aims: The current research investigated parents' views about three aspects…

Attachment studies mostly follow the Western middle-class model in theory and methods. To demonstrate that the assessment of children's caregiving context is an often neglected, but crucial prerequisite for attachment studies, we (a) conducted a literature analysis of attachment research in non-Western contexts and (b) empirically investigated the…

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…
