The vocabulary size and composition of one group of full-term and three groups of low risk preterm children with different gestational ages (GA) were longitudinally compared at 10, 22 and 30 months of age. Expressive vocabulary development was assessed through the CDI. Cognitive development was also assessed at 22 months (Batelle Developmental…

Background: Research findings on vocabulary development in children with Down syndrome are inconsistent. This study aimed to analyse the developmental trend of vocabulary growth in children with Down syndrome and the relationships between vocabulary and chronological and developmental age. Method: Children's vocabulary size was assessed by a…

This longitudinal study examined the predictive associations between cumulative multidomain risk factors and cognitive (IQ), academic (reading fluency), and social adaptive outcomes at 8 to 9 years among 190 children with or without familial risk for dyslexia. Other risk factors included parental and neurocognitive risks assessed when the children…
