Abstract
The present study investigated to what extent children with specific language impairment (SLI) differ in their early numeracy skills, when compared to normal language achieving (NLA) children. It was also explored which precursors were related to the early numeracy skills in both groups. Sixty-one children with SLI (6; 1 years) and 111 NLA children (6; 2 years) were assessed on general intelligence, working memory, naming speed, linguistic ability and early numeracy skills. The results showed lower scores for the children with SLI on logical operations and numeral representations but not on numeral estimations. The variance in numeral estimations was explained by children's intelligence and visual spatial memory. Phonological awareness and grammatical ability explained the variance in logical operations and numeral representations whereas naming speed turned out to be an additional factor in predicting these early numeracy skills of children with SLI.
