Children's moral self-concept (MSC) has been proposed to relate to prosocial behaviour. However, systematic assessments of their interrelations are scarce. The current study examines the early development, structure, stability and interrelation of three key prosocial behaviours and the corresponding dimensions of the moral self-concept. To this end, we use a longitudinal approach with three measurement points during the preschool years at ages 4, 5 and 6 years. We assess three prosocial dimensions of children's MSC through a puppet-interview...

The goals of this study were to examine maternal beliefs about the primary benefits and costs of their children's time spent with friends, and to explore child age and gender differences in these beliefs. Participants were N = 512 mothers (Mchildage  = 10.18 years; 11% ethnic minority). Open-ended responses to questions about the benefits and costs were coded and analysed, with results indicating that mothers consider opportunities for social skills and social-cognitive development a primary benefit of spending time with friends...

The nature of the home mathematics environment (which includes numerical and spatial activities at home) is related to children's spatial and mathematics performance. The current study investigated concrete and digital construction play frequency and relations with spatial and mathematical skills. Participants aged 7-9 years (N = 634) reported their frequency of construction play (concrete and digital) and completed direct measures of spatial ability and mathematics performance. Correlations between measures revealed no association between construction play frequency and outcome measures...

Children have a proclivity to learn through faithful imitation, but the extent to which this applies under significant cost remains unclear. To address this, we investigated whether 4- to 6-year-old children (N = 97) would stop imitating to forego a desirable food reward. We presented participants with a task involving arranging marshmallows and craft sticks, with the goal being either to collect marshmallows or build a tower. Children replicated the demonstrated actions with high fidelity regardless of the goal, but retrieved rewards differently...

This study examined whether the contact emerging adults have with same-gender and other-gender friends, and other-gender romantic partners is associated with their sexist and gender-inequality beliefs, and whether these associations are moderated by their gender or gender contentedness (feeling content with one's gender). Dutch emerging adults (N = 381, 18-25 years old, 51% female) completed an online survey. Hierarchical multiple regression analyses revealed that more other-gender contact was associated with less gender-inequality beliefs and with less hostile sexism in people who felt less content with their gender, but with more hostile sexism in people who feel highly content with their gender...

Previous research in adults has showed that physical performance (i.e., enactment) of instructions at recall leads to better memory compared to verbal recall and that this effect does not rely solely on Working Memory resources. The current study aimed to replicate this finding in children. A group of 32 children encoded simple instructions verbally while engaging in a series of distractor tasks (articulatory suppression, backwards counting and a motor suppression task). Participants recalled information verbally or physically through enactment...

The proliferation of artificial intelligence may pose new challenges to people's moral judgements. We examined moral judgements towards different social actors and their influencing factors in children, adolescents and adults. Moral judgements were measured with ship problems which will ask participants whether they would choose to save humans, dogs, humanoid robots or animaloid robots. Results showed that (1) both adolescents and adults considered humans morally most important, followed by dogs, humanoid robots and animaloid robots...

Early mathematics skills relate to later mathematics achievement and educational attainment, which in turn predict career choice, income, health and financial decision-making. Critically, large differences exist among children in early mathematics performance, with parental mathematics engagement being a key predictor. However, most prior work has examined mothers' mathematics engagement with their preschool- and school-aged children. In this Registered Report, we tested concurrent associations between mothers' and fathers' engagement in mathematics activities with their 2- to 3-year-old toddlers and children's mathematics performance...

The contribution of working memory to mathematics has been extensively studied. It has been proposed that verbal working memory (VWM) and visual-spatial working memory (VSWM) have distinct contributions, but results have been inconclusive. Here, we hypothesized that VWM and VSWM contribute differentially to separate sub-domains of mathematics. To test this hypothesis, we enrolled 199 primary school students and measured their VWM and VSWM with number/letter/matrix backward span tasks, and tested mathematics performance with simple subtraction, complex subtraction, multi-step calculation and number series completion, while controlling for several aspects of cognition...

As misinformation is one of the top risks facing the world today, it is vital to ensure that young people have the confidence and skills to recognize fake news. Therefore, we used co-creation to develop an intervention (called 'Project Real') and tested its efficacy in a proof-of-concept study. One hundred and twenty-six pupils aged 11-13 completed questionnaires before and after the intervention that measured confidence and ability to recognize fake news and the number of checks they would make before sharing news...

What happens when children have formed an impression of a peer based on prior gossip, but later learn from direct observation that the gossip is untrue? We interviewed seventy 5- and 6-year-old children in Zhejiang, China. They first heard conflicting positive and negative gossip about an absent third party, and subsequently learned which piece of gossip was true. Initially, both 5- and 6-year-old children tended to endorse the positive rather than the negative gossip. However, when they learned about the inaccuracy of the positive gossip based on their own direct observation, 6-year-old children subsequently doubted it, whereas 5-year-old children showed no such shift...

Prosocial behaviour can be defined as any voluntary action that is performed to benefit another individual. Despite accumulating evidence of the importance of environmental variables (e.g., socioeconomic status; SES), and individual characteristics (e.g., theory of mind - ToM - skills), in influencing prosocial behaviours in young children, it is unknown how these factors relate to the underlying motivations for prosocial behaviours. Accordingly, both extrinsically (sharing) and intrinsically (generosity)-guided prosocial behaviours are measured in this study...

Recent models of emotion regulation (ER) highlight the need to construct tools that assess ER in different contexts. This paper describes the development and validation of the Contextualized Emotion Regulation Survey for Adolescents (CERSA). This questionnaire assesses ER strategies and abilities in three situations that elicit specific emotions (i.e. sadness, fear and anger). Data were collected from a sample of 840 adolescents who completed the CERSA (M age  = 14.75; SD age  = 1...

The study examined the presence and nature of a relationship between 13 early childhood educators' mental state language (MSL) and 77 preschool children's (3- to 5 years) Theory of Mind (ToM). Educator language samples were elicited during two naturalistic group-time contexts, wordless picture book storytelling and an instructional building task. MSL was coded according to a comprehensive scheme that captures facets of MSL content and quality. To account for well-established determinants of ToM, a range of child- and family-level factors were also measured...

Rituals are fundamental social acts that structure relationships and enable the filtering of important cognitive attributes (e.g. working memory and inhibitory control) that make humans what they are today. This study investigated the influence of model age and familiarity on the reproduction of ritual behaviour in five-year-old children. Through an exploration of these factors, this study sheds light on the cognitive mechanisms children use to comprehend and replicate rituals. Ninety-eight five-year-old children were divided into two groups: an experimental group, which observed an adult or child model, either familiar or unfamiliar to them, demonstrating eight ritual acts; and a control group, which received no video demonstration...

Income inequality is growing in many parts of the world and, for the poorest children in a society, is associated with multiple, negative, developmental outcomes. This review of the research literature considers how childrens' and adolescents' understanding of economic inequality changes with age. It highlights shifts in conceptual understanding (from 'having and not having', to social structural and moral explanations), moral reasoning and the impact of the agents of socialization from parents to the media and cultural norms and discourses...

This study examined how children's attentional orientation towards environmental cues, dispositional sympathy and inhibitory control were associated with their ethical guilt. Participants were 4- and 6-year-old children (N = 211; 55% male) from ethnically diverse backgrounds. To assess ethical guilt, children were presented with two vignettes depicting ethical violations and reported how they would feel and why, if they had committed those transgressions. Using eye tracking, we calculated attentional orientation as the percentage of time children attended to other-oriented (i...

Difficulties in emotion regulation have been consistently associated with various psychological difficulties, including anxiety and depression; however, less is known about the directionality of this relationship, particularly in adolescents. In addition, early parent-child attachment quality has been closely linked to the development of emotion regulation. Previous studies have proposed an overarching model in attempt to describe the developmental trajectory of anxiety and depression from early attachment, albeit with several limitations that are discussed in this paper...

Effective reciprocal communication is a vital component in forming and maintaining social relationships. Peer social play may provide a particularly important context for communicative skill development, as sophisticated negotiation and exchange are required to coordinate play. We focus on connectedness, a property of conversation referring to the topical relation between speakers' turns, to understand how partners coordinate ideas to build a shared play experience. The present study uses a longitudinal secondary analysis approach to drive forward our understanding of the individual and shared influences that contribute to connectedness during peer social play...

A growing body of research has shown that parent-child math activities predict children's math competence. However, observational studies are limited. This study investigated maternal and paternal scaffolding behaviours in three types of parent-child math activities (i.e., worksheet, game and application activities) and their associations with children's formal and informal math abilities. Ninety-six 5-6-year-olds participated in this study with their mothers and fathers. All children completed three activities with their mothers and three comparable activities with their fathers...
