This study evaluates the Children's Worlds Psychological Well-Being Scale (CW-PSWBS) within a diverse international cohort of children aged 10 and 12, utilising Classical Test Theory (CTT) and Item Response Theory (IRT) methodologies. Through a detailed psychometric analysis, this research assesses the CW-PSWBS's structural integrity, focusing on…

Selecting whose words to trust profoundly impacts children's learning behaviours. This study investigated Western and East Asian children's trust preferences for informants based on social dominance and its potential association with cultural factors. Sixty-six European American children in the United States (M = 5.44 years, SD = 0.80 years) and…

Children comprehend iconic gestures relatively later than deictic gestures. Previous research with English-learning children indicated that they could comprehend iconic gestures at 26 months, a pattern whose extension to other languages is not yet known. The present study examined Turkish-learning children's iconic gesture comprehension and its…

Recent research on advanced theory of mind (ToM) has questioned the extent to which existing ToM measures capture a single construct, particularly for groups understudied in developmental research. The present study examined the factor structure of one of the most commonly used advanced ToM measures, the Strange Stories task, in samples of low-…

This study investigated whether familiarity and expertise of a dissenter would lessen the trust of a three-person majority among preschoolers in a Chinese sample. The results indicated that preschoolers preferred to trust a majority rather than a stranger dissenter. However, when familiarity and expertise of the dissenter were manipulated in the…

Delay of gratification tasks have an impressive predictive value for various outcomes and are designed to measure self-regulation. Since many behavioural and psychological conditions in children are related to limitations in self-regulation, the extent to which delay tasks can be used as a screening for the detection of psychopathology is…

Previous studies have shown that social exclusion can have negative effects on the well-being of children and adolescents. However, there is inconsistent evidence regarding how the impact of social exclusion changes with age. This study used the Cyberball paradigm to investigate the effects of exclusion and subsequent inclusion on primary needs…

The study examined storytelling prosody (i.e., prosodic variations in retelling a story) and the relation with oral language in Taiwanese preschool children. One hundred and twenty-eight preschool children aged 4 and 5 were recruited and given the following tasks: nonverbal intelligence, vocabulary, syntax, and storytelling prosody. Children's…

This study explored the development of theory of mind (ToM) in 80 Swedish-speaking 3- to 5-year-olds, a previously unstudied language and culture. The ToM scale was translated and tested in a Swedish context. The results show that the ToM abilities improve significantly with age. In addition, a gender difference was observed for the whole sample,…

Generic descriptions (e.g., 'girls are emotional') are argued to play a major role in the development of essentialist reasoning about social categories. Although generics are prevalent across languages, studies exploring if and how generic language leads to essentialism have almost exclusively been conducted in English-speaking communities and…

A systematic review was conducted to gain a more nuanced understanding of similarities and distinctions across countries in the development of executive functions (EF). The review includes 26 studies, with child and adolescent participants, that were published between 2006 and 2018. Both similarities and differences within developmental patterns…

Literature suggests that motor skills are associated with other areas of development or domains, such as language and math, especially at early ages. These results are mainly based on studies developed in medium-to-high sociocultural contexts. Thus, this study was conducted in a medium-to-low-income area. The aim was to know the 4-5 years old…

Many studies have found that a majority of boys and girls prefer to play with toys that are typed to their own gender but there is still uncertainty about the age at which such sex differences first appear, and under what conditions. Applying a standardized research protocol and using a selection of gender-typed toys, we observed the toy…

We estimated risk factors associated with suspected neuropsychomotor developmental delay at age 2 years, in a birth cohort in the Brazilian Amazon. The Maternal and Child Health and Nutrition in Acre (MINA-Brasil) study is a population-based birth cohort involving children born between July 2015 and June 2016 in the municipality of Cruzeiro do…

Executive function (EF) is essential for academic achievement, successful work, and physical and mental health. Although evidence shows that several factors have been linked to EF, these results are mixed. This study aims to identify both biological and environmental variables associated with impaired EF in preschoolers. This study was a…
