Purpose: The aim of this study was to gain more insight into the linguistic characterization of dyslexia by investigating vocabulary acquisition. In a previous study, vocabulary at 17 months of age appeared to be related to familial risk (FR) of dyslexia. The aim of this study was to investigate how the differences in lexical composition further…

Discriminative language markers and predictive links between early language and literacy skills were investigated retrospectively in the Jyvaskyla Longitudinal Study of Dyslexia in which children at familial risk for dyslexia have been followed from birth. Three groups were formed on the basis of 198 children's reading and spelling status. One…

This study, with 30 language learning-disabled, reading-disabled, and normal primary school children, found that clause structure complexity, fluency, and grammatical and phonemic accuracy tended to be highest when children were discussing absent referents, providing explanations and stories, and giving unshared information. These effects were…

A longitudinal study revealed that 14 normal and 29 specifically language impaired (SLI) four to eight year-olds developed skills in receptive and expressive language and speech articulation over the three to four years between evaluations. However, SLI subjects developed at a slower rate and the majority of them manifested reading impairment at…

Relationships between phonological coding abilities and reading outcomes have implications for differential diagnosis of language-based reading problems. The theoretical construct of specific phonological coding ability is explained, including phonological encoding, phonological awareness and metaphonology, lexical access, working memory, and…

The syntactic development of preschoolers (n=22) who later became disabled readers was compared to that of similar children who became normal readers. Expressive and receptive syntactic abilities were examined from age 30 to 60 months. The dyslexic group was poorer on all measures until age five, when both groups exhibited similar syntactic…

The paper describes the development of the "Test of Thought and Language" (Total) which is intended to allow first grade teachers to determine if students are ready for phonics instruction or if, for some students, the curriculum should first develop language concepts, structures and thinking processes. Background information for the…
