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…

This study aimed to determine and describe the influence of psycholinguistics and metacognition on the ability of physics education students to use verbal language in the learning process. Quantitative research is used to measure the level of influence between variables, and then the case study is used to determine the sample. Based on the data,…

The present study examines the link between children's number of older siblings and their cognitive development, as measured by executive function (EFs) skills and verbal skills (VIQ) in a sample of 1,302 4-year-old children (54% boys) living in rural Pakistan. Specifically, we investigate whether the links between the number of older siblings and…

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.…

Understanding gender differences in human cognitive development may contribute to understanding the gender differences in outcomes in cognitive ageing. However, evaluation of this topic has been hindered by a lack of representative, longitudinal data from different aged cohorts measured on the same cognitive tests. Gender differences in cognitive…

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…

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…

This article assessed changes in the association between single motherhood and children's verbal cognitive ability at age-11 using data from three cohorts of British children, born in 1958 (n = 10,675), 1970 (n = 8,933) and 2000 (n = 9,989), and mediation analysis. Consistent with previous studies, direct effects were small and insignificant. For…

Dietary intake can affect the physical, cognitive, and socioemotional development of young children. Few studies have explored the relationships between dietary intake and the cognitive and socioemotional dimensions of school readiness. This study aimed to investigate the longitudinal associations between children's dietary intake in early…

Previous research shows that Early Childhood Education (ECE) positively impacts cognitive outcomes later in life. Few studies examine the impacts of ECE in developing countries. We use data from the Young Lives project in Vietnam with 2SLS regressions to estimate the impact of years spent in ECE on cognitive outcomes in adolescence. We find that…

This paper attempts to investigate the repetition of Relative Clauses (RCs) in Mandarin children with Developmental Language Disorder (DLD) (aged 4; 5 to 6; 0) and their typically developing (TD) peers. The results of a sentence repetition task indicate that Mandarin children with DLD perform significantly worse than both groups of TD children,…

The aim of the current study was two-fold. First, it evaluated the influence of bilingualism on syntactic abilities and verbal memory of children with High Functioning Autism (HFA). Second, it explored the relationship between syntactic abilities and verbal memory of children with HFA and typical language development (TLD). Eighty-six monolingual…

The development of emotion understanding in young Chinese preschoolers was examined. The overall developmental trend, as measured by the Test of Emotion Comprehension (TEC), proved similar to that found among preschoolers in Western Europe. However, Chinese children performed better at understanding the distinction between real and apparent…

Rejection by peers has devastating effects on children's social-cognitive development. As language difficulties have been found to be one of the underlying causes of peer rejection, the present study focused on the relation between these two variables. Specifically, this study was the first to test a hypothesized model connecting children's level…

Children start preschool with large individual differences in their early numerical abilities. Little is known about the importance of heterogeneous patterns that exist within these individual differences. A person-centered analytic approach might be helpful to unravel these patterns and the cognitive and environmental factors that are associated…
