This longitudinal investigation on Dutch children with Specific Language Impairment (SLI) aimed at determining the predictive value of statistically uncorrelated language proficiencies on later reading and spelling skills in Dutch. Language abilities, tested with an extensive test battery at the onset of formal reading instruction, were represented by four statistically uncorrelated factors: lexical-semantic abilities, auditory perception, verbal-sequential processing, and speech production. All factors contributed significantly to the prediction of word reading and spelling development seven months later. Verbal-sequential processing was the strongest predictor for both word decoding and spelling. Furthermore, autoregression effects of word decoding and spelling were strong and verbal-sequential processing had predictive value on word spelling nineteen months later when pre-existing spelling abilities were accounted for. Children with SLI and normal literacy skills performed better on most of the language and language-related measures than children with SLI and poor literacy skills.As a result of this activity, readers will describe four language domains that are related to later literacy skills in children with Specific Language Impairment (SLI). As a result of this activity, readers will recognize the predictive value of each of these language domains and the important role of verbal-sequential processing in learning to decode and writing words for children with SLI. As a result of this activity, readers will recall the differences in language proficiencies between children with SLI who develop normal literacy skills and those who encounter literacy problems.
