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…

This study investigated the complex relationship between false-belief (FB) understanding, structural language and pragmatic communication in typically developing children. A total of 78 Finnish children, aged from 4 to 6 years, including an equal number of boys and girls, participated in this study. In the first instance, the study explored the…

Early detection of autism spectrum condition is crucial for children to maximally benefit from early intervention. The study examined a machine learning model predicting the increased likelihood for autism from wellness records from 0 to 24 months. The study included 591,989 non-autistic and 12,846 autistic children. A gradient boosting model with…

Background/purpose. This study aimed to explore various demographic and relational factors affecting adolescents, with a particular focus on their self-esteem. Materials/methods. This study employed a descriptive and correlational research design to gather quantifiable data and examine the relationship between parent-adolescent dynamics and…

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…

This study contributes to our understanding of children's development of map-reading skills through a systematic 'step-by-step approach'. Utilising an ecological research design, we investigated how children perceive and utilise maps in a large-scale outdoor environment. A total of 156 children, aged 5-11 (both boys and girls), participated in the…

Children's microcultures consist of small peer communities that they develop with distinct rules and roles operating outside of traditional daily activities. Presently, there is little understanding for how children may develop microcultures during competitive play, where they attempt to outperform their peers. In this study, we address the…

Research to date has shown longitudinal changes in conscientiousness during early and middle adolescence, but most studies have been conducted in Western countries. The present study aimed to examine the pattern of mean-level conscientiousness change at the transition into early adolescence among a Chinese sample using curve of factors (CUFFS)…

Gender differences in early childhood development are under-researched in low- and middle-income countries (LMICs) where almost 90% of the world's young children live. This study examines the direction, magnitude, and variation of gender similarities and differences in 3- and 4-year-olds' early childhood development in 71 low- and middle-income…

Risky play provides various benefits to child growth and development. The culture of overprotection among Hong Kong parents have decreased young children's opportunities to engage in play that involves physically challenges. This study expanded our understanding of parents' views and behaviors on allowing their preschool children opportunities for…

Children's speech is influenced by the speech they hear, in particular by the parental speech addressed directly to them. The aim of this study was to analyse toddlers' speech with their parents and to investigate the influence of specific characteristics of child-directed speech on child speech in real time during mother-child and father-child…

Background: The coronavirus (COVID-19) pandemic and associated public health restrictions created unprecedented challenges for parents and their young dependent children. While psycho-social impacts of natural disasters on families are well studied, a typography of parent specific concerns in the COVID-19 context was yet to be articulated.…

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…

Increasing research shows pubertal development accelerates following threats while it decelerates following deprivation. Yet, these environmental stressors are unlikely to occur in isolation. We investigated how war exposure and energetic stress impact pubertal development using data from the longitudinal Biological Pathways of Risk and Resilience…

The empirical link between children's cognitive ability and parental risk attitudes has been understudied. Specifically, an individual's educational outcome may reflect the decisions made on their behalf by parents, reflecting their risk attitudes. This paper aims to fill gaps in the existing literature by investigating whether parental risk…
