Structural equation modelling was used to investigate the predictive associations between kindergarten developmental, socio-behavioural, and biotic influences on third grade achievement among a nationally representative sample of low-SES children. The findings validate the understanding that developmental and learning trajectories start early in…

Measurement of early childhood development at the population level has traditionally been neglected in Latin America. In this context, Uruguay stands out for having two population-based protocols: the Nutrition, Child Development and Health Survey (ENDIS), a home survey, and the School Readiness - Child Development Inventory (INDI). This paper…

The development of cognitive and motor skills early in life is essential for a child's global development and learning, which in turn influences later health and well-being. This cross-sectional study aimed to determine the associations between sociodemographic factors and nutritional factors with cognitive and motor delays in infants aged 6-12…

Playing is essential for the development of higher psychological functions. The purpose of this study is to demonstrate that playing constitutes an essential step in children's socio-cognitive development by describing playtime as the indicator of the gradual overcoming of self-centred thinking, with a view to acquiring new social adjustment…

The first year of a child's life has been considered important in shaping their cognitive development. The research literature has identified area-based socio-economic disadvantage as a possible risk factor for cognitive development but has suggested that various factors may facilitate children's resilience to socio-economic disadvantage. This…

The study seeks to understand the relation between preschool children's mode of participation and negotiation strategies during play and their theory of mind (ToM) development in the Hong Kong context. Forty-two 5-year-old children were recruited. Their emotional and cognitive ToMs were assessed along with expressive language ability. Children's…

We aimed to investigate stress response regulation, temperament, cognitive and language abilities and family SES in children who entered kindergarten before two years of age. Whilst childrens stress regulatory systems are vulnerable to environmental influences little is known about how temperament and family characteristics impact on stress…

Many studies propose that chess is a game requiring cognitive skills and has positive effects on mental development. In recent years, chess training has also been emphasised as important during the early childhood period. However, no studies have been done with six-year-old children. The purpose of this study was to investigate whether or not…

Previously we found in preschool that child-directed pretend play in small playing groups importantly improves cognitive competence in mixed-age environment and that the effect is based on close coupling between affective and cognitive domain. To foster affective and cognitive intertwining, it is reasonable to select the most favored pretend plays…

We studied the long-term cumulative effects of two common indices of childcare--the total number of hours of non-maternal care and the mean hour-weighted child-to-caregiver ratio per caregiving situation--on mental development and socioemotional adjustment from birth to 4.5 years old in a non-risk middle-class sample of girls and boys after taking…
