Perspective taking and cognitive flexibility are important abilities for navigating our everyday lives. In this longitudinal study with 108 children (61 girls, mostly White), we investigated the developmental relation between Level 1 perspective taking at 27 months of age and Level 2 perspective taking at 52 months of age as well as relations to…

Previous research on children's knowledge about the mind has primarily focused on their comprehension of false beliefs, leaving the conceptualization of thoughts and thinking less explored. To address this gap, we developed a new assessment tool, the interview about the mind (IaM), to assess children's understanding of the mind. Two studies…

Diverse mechanisms account for the familial aggregation of certain personality traits and externalizing psychopathology. We explored the roles of positive and negative parenting as mediators of longitudinal associations between parents' maladaptive personality traits and their children's inattention/hyperactivity problems. We collected self,…

Economic difficulties in early childhood are associated with significant adverse long-term socioemotional and cognitive outcomes. In this study, we examine an understudied financial stressor that is often observed during periods of high unemployment--transient familial financial stress (TFS). We use the early childhood longitudinal study--(birth)…

Using data from the Early Childhood Longitudinal Study Kindergarten Class of 2010-2011 (n = 11,000), this study examined the developmental outcomes of 5-year-old children in multigrade classrooms (combined prekindergarten and kindergarten classrooms serving 3-, 4-, and 5-year-olds) compared with those of 5-year-olds attending kindergarten-only…

Caregivers' narrative elaborations have been consistently shown to relate to language, literacy, and cognitive skills in children. However, research with Latinos yields mixed findings in terms of how much caregivers elaborate and the benefits of elaborations for Latino children's development, especially within booksharing contexts. Moreover,…

Executive functions (EF) are an important predictor of later adaptive development. A number of environmental influences, such as parenting, have been suggested as important promoters of EF development. However, behavioural genetic research has demonstrated that many environmental influences could be affected by genetic influences. Therefore, it is…

In this study, we address the construction of the first symbolic uses of objects in contexts of triadic interaction (adult-child-object). We assume that symbolic productions are based on public rules of the use of objects previously agreed by the community. The first symbols are not rooted in any literal, evident reality, but in shared rules of…

Despite the growing body of research on parents' beliefs and practices, relatively little is known about the relations between parents' knowledge of children's development, home-based activities, and children's early reading and math skills. This study used data from the Early Childhood Longitudinal Study-Birth Cohort to examine the differences in…

Finnish students' international success in mathematics has been largely explained by the high-quality compulsory basic education system, while increasing evidence suggests that early childhood contexts can also promote development long before formal instruction begins. This study examined, in a sample of 66 mother-infant dyads, 2 early contextual…

Children showing poor executive functioning may not fully benefit from learning experiences at home and school and may lag behind in literacy skills. This hypothesis was tested in a sample of 276 kindergarten children. Executive functions and literacy skills were tested at about 61?months and again a year later. In line with earlier studies,…

The development of proficient communication skills in infants and toddlers is an important component to child development. A popular trend gaining national media attention is teaching sign language to babies with normal hearing whose parents also have normal hearing. Thirty-three websites were identified that advocate sign language for hearing…

This study investigated the role of parenting knowledge of infant development in children's subsequent language and pre-literacy skills among White, Black and Latino families of varying socioeconomic status. Data come from 6,150 participants in the Early Childhood Longitudinal Study-Birth Cohort. Mothers' knowledge of infant development was…

This research investigated the developing inter-relationships between language, graphic symbolism and symbolic play both concurrently and longitudinally from the fourth to the fifth year of childhood. Sixty children ("n"?=?60) aged between 3 and 4?years completed multiple assessments of language and assessments of graphic symbolism,…

Self-produced locomotion is regarded as a setting event for other developmental transitions in infancy with important implications for socioemotional development and parent-child interaction. Using an age-held-constant design, this study examined changes in reported infant behaviour and maternal proactive/reactive control and compared them with…
