Maternal substance use and unpredictable maternal sensory signals may affect child development, but no studies have examined them together. We explored the unpredictability, frequency and duration of maternal sensory signals in 52 Caucasian mother-child dyads, 27 with and 25 without maternal substance use. We also examined the association between…

Self-regulation develops rapidly during early childhood and is essential for academic and social adjustment. However, previous research has attempted to define the conceptualization and structure of self-regulation differently, leaving the field with an incomplete picture. The nature of the relations between self-regulation and early child…

Problem solving is an important cognitive skill that children use to plan and navigate various developmental and social tasks. Although previous research was theory-grounded and systematic, to our knowledge, no research has observed and documented children's problem solving as a primary objective in naturalistic developmental contexts, such as…

A long-standing debate in the field of numerical cognition concerns the degree to which symbolic and non-symbolic processing are related over the course of development. Of particular interest is the possibility that this link depends on the range of quantities in question. Behavioral and neuroimaging research with adults suggests that symbolic and…

Identifying and describing children's play behaviours is an important component of evaluating child development. The Behaviour Mapping Schedule is a direct observational tool which aims to describe and quantify children's play behaviours but is yet to undergo reliability testing. This study aimed to determine the intra- and inter-rater reliability…

Mutualism is a developmental theory that posits positive reciprocal relationships between distinct cognitive abilities during development. It predicts that abilities such as language and reasoning will influence each other's rates of growth. This may explain why children with Language Disorders also tend to have lower than average non-verbal…

The current prospective cohort study investigated whether early perceptual abilities, measured at preschool age, could predict later intellectual abilities at school age in a group of 41 autistic (9 girls, 32 boys) and 57 neurotypical children (29 girls, 28 boys). More than 80% of the autistic children were considered minimally verbal.…

Executive functions (EF) are domain-general cognitive skills that predict foundational academic skills such as literacy and numeracy. However, less is known about the relation between EFs and science achievement. The nature of this relation might be explained by the theory of mutualism, which states that development is the result of complex and…

The recent introduction of inclusive schooling settings in France has allowed children with autism spectrum disorder (ASD) as young as 3 years to benefit from teaching adapted to their special needs, while sharing the same educational environment as their typical peers. The present study examined (1) whether children with ASD attending an…

This study explores the influence of kindergarten care on the social and cognitive development of Saudi Arabian and international students in early childhood education in Saudi Arabia. A mixed-methods approach assessed the development of 302 children, aged between 5 years and 11 months to 7 years, and their mothers in Saudi Arabia's Eastern…

Executive functions (EF), including working memory, inhibition, and cognitive flexibility, vary as a function of socioeconomic status (SES), with children from economically disadvantaged backgrounds having poorer performance than their higher SES peers. Using observational methods, we investigated cognitive stimulation in the home as a mechanism…

Representational theory of mind--the ability to represent others' mental states and understand that these beliefs can be different from one's own and reality--emerges in early childhood alongside other meta-representational abilities, such as understanding that an image can be perceived in multiple ways. Limited research has suggested that…

Intellectual impairments in preschoolers have been widely studied. A regularity that emerges is that children's intellectual impairments have an important impact on later adjustments in life. However, few studies have looked at the intellectual profiles of young psychiatric outpatients. This study aimed to describe the intelligence profile of…

It is argued that corporal punishment produces bad outcomes in both the short run and the long run. Instead of making students more attentive or motivated, corporal punishment leads to more delinquent behavior. In most developed countries, corporal punishment is banned in schools. However, in many developing countries, even if corporal punishment…

Parent-grandparent coparenting is a common phenomenon in mainland China; however, little is known about its relationship with children's cognitive development. This study investigates the links between parent-grandparent coparenting and young children's executive function (EF) and examines the potential mediating role of maternal parenting between…
