This study examined the auditory-verbal and visual-spatial skills of children with Specific Language Impairment (SLI) within a complex working memory framework that included both storage and processing. Twelve children with SLI and 12 age matched peer repeated words or remembered object locations (storage); then, in more demanding versions of these tasks, categorized the words by size of referent or the objects by shape before recall (storage + processing). Children also completed a narrative task. Findings indicated that children with SLI had a reduced auditory-verbal working memory capacity relative to their peers, particularly when processing demands were high. There were no group differences in the visual-spatial tasks. Further research is needed to reconcile this finding with reports elsewhere that children with SLI do have deficits in the visual-spatial domain. Finally, significant correlations between the complex auditory-verbal memory tasks and the narrative task, indicated links between working memory and text formulation processes.
