The present study was the first to investigate the ability to selectively trust reliable informants in a sample of Brazilian preschool children from two different socioeconomic backgrounds. Ninety-three 3- and 4-year-old children, equally distributed across a low- and medium-SES group, participated. A standard selective trust task was used.…

The reliability and validity of the Children's Social Understanding Scale (CSUS) was further assessed by examining fathers' as well as mothers' reports of children's social understanding, along with behavioural measures of children's mental state understanding. 112 families with children aged 38 to 64 months participated with both parents filling…

Children have repeatedly been shown to selectively prefer to learn from previously accurate informants rather than those who have been inaccurate in the past. However, the stability of individual differences in performance on such tasks has yet to be studied. We presented preschoolers with two identical selective learning tasks conducted one week…

Perspective taking is a fundamental skill that helps us to understand others' thoughts, feelings and perceptions. Past studies have shown that there were significant relations between young children's perspective taking abilities and age, gender, formal schooling and socioeconomic status. The present study was conducted to investigate the…

To date, cross-cultural studies on Theory of Mind (ToM) have predominantly focused on preschoolers. This study focuses on middle childhood, comparing two samples of mainland Chinese (n = 126) and Australian (n = 83) children aged between 5.5 and 12 years. Strange Stories, the most commonly used measure of ToM, was employed. The study aimed to…

The two prior studies that have examined associations between the sibling constellation and theory of mind in autism spectrum disorder yielded discrepant findings. Thus, efforts to better understand the sibling-theory of mind link in autism spectrum disorder are necessary. This study examined a sample of prekindergarten- and kindergarten-aged…

In 2 cross-lagged, longitudinal studies we contrasted parental talk about want in a single context versus multiple contexts. Study 1 examined thirty-two 2 year olds, with mothers describing pictures to children. Mothers could use want in zero, one, or multiple contexts. Children whose mothers used want in multiple contexts experienced a…

Research has documented various family and individual risk factors associated with severe conduct problems, but little is known about the developmental origins of children who engage in both aggressive and prosocial interactions with others. The present study utilized growth-mixture modeling to identify distinct trajectories of physical aggression…

This investigation was aimed at studying the relations between executive functions (EFs) and categorical emotion understanding while controlling for preschoolers' IQ, language ability and theory of mind (ToM). Specifically, we wanted to analyse the association between emotion understanding and set shifting, due to the lack of studies with this EF.…

A critical skill in emergent writing is the developing ability to take the perspective of different readers; however, the precursors of this skill have not yet been identified. In this longitudinal study, 105 children (90 after attrition) were tested at 3 time points: pre-kindergarten (3-4 years old, n = 105), kindergarten (5 years old, n = 97),…

The present study investigated how Chinese children develop theory of mind (ToM) in a language environment with limited mental state talk that is rich in behavior discourse. In Study 1, 60 mothers shared a wordless storybook with their 3-4-year-olds. The children completed two false-belief tasks and the Peabody Picture Vocabulary Test-Revised at…

In this study the authors investigated whether training preschool children in the use of mental state lexicon plays a significant role in bringing about advanced conceptual understanding of mental terms and improved performance on theory-of-mind tasks. A total of 70 participants belonging to two age groups (3 and 4 years old) were randomly…

Typically language development in children closely coincides with development in many other areas. This makes it difficult to determine whether observed correlations are coincidental or causal in nature. The three studies presented here explore these relationships by looking at two populations of learners who are delayed in exposure to English,…
