Copy Skills and Writing Abilities in Children With and Without Specific Learning Disabilities.

Copying a text quickly and accurately is important both in school and in daily life. However, this skill has never been systematically studied, either in children with typical development (TD) or in children with specific learning disabilities (SLD). The aim of this research was to study the features of a copy task and its relationship with other writing tasks. For this purpose, 674 children with TD and 65 children with SLD from Grades 6 through 8 were tested with a copy task and other writing assessment tasks, measuring three aspects of writing: handwriting speed, spelling, and expressive writing. Children with SLD performed worse on the copy task, both in terms of speed and accuracy, than children with TD. Copy speed was predicted by grade level and by all three major writing skills for children with TD but only by handwriting speed and spelling for children with SLD. Copy accuracy was predicted by gender and the three major writing skills for children with TD but only by spelling for children with SLD. These results suggest that children with SLD also have difficulty copying a text and benefit less than children with TD from their other writing skills.
