This study aimed to investigate the gap between adaptive functioning and cognitive functioning, especially verbal and nonverbal intelligence quotient (IQ) in Chinese children with ASD. We systematically explored cognitive functioning, ASD severity, early signs of developmental abnormalities, and socioeconomic factors as mediating factors of…

Background: Developmental research provides considerable evidence of a strong relationship between verbal and visuospatial working memory (WM) and mathematics ability across age groups. However, little is known about how components of WM (i.e., short-term storage, processing speed, the central executive) might relate to mathematics sub-categories…

Williams syndrome (WS) is a rare genetic syndrome. As with all rare syndromes, obtaining adequately powered sample sizes is a challenge. Here we present legacy data from seven UK labs, enabling the characterisation of cross-sectional and longitudinal developmental trajectories of verbal and non-verbal development in the largest sample of…

Spatial language and ability play important roles in children's cognitive development. Spatial ability in kindergarten predicts achievement in reading, math, science, and technology in primary school and therefore constitutes an important skill set in preparation for school entrance. Good spatial thinking skills are required for learning in…

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…

As adults, we represent and think about number, space, and time in at least two ways: our intuitive--but imprecise--perceptual representations, and the slowly learned--but precise--number words. With development, these representational formats interface, allowing us to use precise number words to estimate imprecise perceptual experiences. We test…

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…

The primary objective of this study was to describe cognitive and pre-academic skills of children born preterm (< 30 weeks gestational age) at preschool age. A secondary objective was to relate cognitive functioning at preschool age to developmental scores obtained using the Bayley Scales of Infant and Toddler Development-Third Edition (Bayley…

Australian children aged 6-9 years (N = 120, 71 females; data collected in 2021-2022) were tasked with remembering the locations of 1, 3, 5, and 7 targets hidden under 25 cups on different trials. In the critical test phase, children were provided with a limited number of tokens to allocate across trials, which they could use to mark target…

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 purpose of this pilot study was to explore cognitive performance and visual motor integration, and investigate the relationship between them in preschool children in a community. Forty-nine participants were selected by stratified random sampling from a local community school and community child development center in Thailand. The instruments…

Early number skills represent critical milestones in children's cognitive development and are shaped over years of interacting with quantities and numerals in various contexts. Several connectionist computational models have attempted to emulate how certain number concepts may be learned, represented, and processed in the brain. However, these…

Purpose: The purpose of the present study was to investigate the relationship between speechreading ability, phonological skills, and word reading ability in typically developing children. Method: Sixty-six typically developing children (6-7 years old) completed tasks measuring word reading, speechreading (words, sentences, and short stories),…

School readiness is recognized as one of the key starting points for children's further success in their school work and in their subsequent career. However, many kindergarten teachers still miss and long for a comprehensive, reliable and standardized diagnostic tool which could help them recognize the level of children's school readiness. That is…

Cognitive tasks are seldom evaluated on their ability to provide valid and reliable measurements of the construct they intend to measure. This scarcity of psychometric evaluations makes it challenging to evaluate replications of experimental effects and to relate performance in cognitive tasks to other constructs of interest. In developmental…
