During human childhood, brain development and body growth compete for limited metabolic resources, resulting in a trade-off where energy allocated to brain development can decrease as body growth accelerates. This preregistered study explores the relationship between language skills, serving as a proxy for brain development, and body mass index at…

First-order and advanced theory of mind (ToM and AToM), and their structures and relations were investigated in 229 children aged 5-8 years. ToM was assessed using 6 tasks from the first-order ToM scale, while AToM was measured using an 18-item battery (higher-order false-belief understanding; strange stories; faux pas test; eyes test;…

This report summarizes research about development during the first 3 years of life. It highlights research in domains that are foundational for later school readiness and success, including: (1) perceptual, motor, and physical development; (2) social and emotional development; (3) approaches to learning; (4) language and communication; and (5)…

Background: Children with language impairment (LI) show heterogeneity in development. We tracked children from pre-school to middle childhood to characterize three developmental trajectories: resolving, persisting and emerging LI. Methods: We analyzed data from children identified as having preschool LI, or being at family risk of dyslexia,…

Self-regulation emerges throughout early childhood, and predicts later success in socially and cognitively challenging situations. Vygotsky proposed that symbols, particularly words, serve as mental tools to be used in service of self-regulation. Cross-sectional research indicates a positive but inconsistent association between language and…

The most popular topic in theory-of-mind research has been first-order false belief: the realization that it is possible to hold false beliefs about events in the world. A more advanced development is second-order false belief: the realization that it is possible to hold a false belief about someone else's belief. This article reviews research…

The study investigated attentional processes of 32 preschool children with congenital visual impairment (VI). Children with profound visual impairment (PVI) and severe visual impairment (SVI) were compared to a group of typically developing sighted children in their ability to respond to adult directed attention in terms of establishing,…

Deferred imitation has long held a privileged position in early cognitive development, considered an early marker of representational thought with links to language development and symbolic processes. Children with autism have difficulties with several abilities generally thought to be related to deferred imitation: immediate imitation, language,…

Existing data on metalinguistic skills are reviewed and then grouped according to the cognitive strategies children appear to employ in resolving metalinguistic tasks. (Author/MP)

Preschoolers' event descriptions indicate that they are able to engage in displaced reference, use timeless verb forms, report optional and conditional relationships, appropriately sequence events, engage in temporal reversibility, and appropriately use a number of relational terms, all at a much younger age than has traditionally been believed…

Recent research data contest Piaget's conclusion that preschool children are totally egocentric, incapable of taking different perspectives, and prevented from acting altruistically. Children are able to decenter when experiments enable children to use their knowledge of very basic human purposes, intentions, and interactions. (Author/DB)

Attention regulation was studied with 35 children with Down syndrome, ages 13-42 months, and 23 children with typical development, focusing on alternating looks between a person and an object, social referencing (using emotional responses of others to appraise ambiguous events), and links to language and cognitive development. (SW)

Examined the associations among speech perception, phonological awareness, naming speed, verbal memory, and word reading. Multiple measures were administered to 136 3rd- and 4th-grade children. Results indicated that naming speed was particularly highly associated with speech perception, whereas phonological awareness was substantially correlated…

Biological theories of adaptation are used to generate a model of human cognitive development in which physiological and cognitive change in aged persons can be understood as an adaptive stage of development. Related literature is reviewed that focuses on the elderly as information transmitters and on the psychology of "telling."…

This article outlines six primary stages of a child's development. These basic functions show the way mental capacities work together as a team. Cognitive, motor, language, emotional, and social skills act together to help the child learn to deal with the world. Helping a child through these stages and fostering these core capacities requires a…
