title: Phonological working memory in German children with poor reading and spelling abilities.
abstract: Deficits in verbal short-term memory have been identified as one factor underlying reading and spelling disorders. However, the nature of this deficit is still unclear. It has been proposed that poor readers make less use of phonological coding, especially if the task can be solved through visual strategies. In the framework of Baddeley's phonological loop model, this study examined serial recall performance in German second-grade children with poor vs good reading and spelling abilities. Children were presented with four-item lists of common nouns for immediate serial recall. Word length and phonological similarity as well as presentation modality (visual vs auditory) and type of recall (visual vs verbal) were varied as within-subject factors in a mixed design. Word length and phonological similarity effects did not differ between groups, thus indicating equal use of phonological coding and rehearsal in poor and good readers. However, in all conditions, except the one that combined visual presentation and visual recall, overall performance was significantly lower in poor readers. The results suggest that the poor readers' difficulties do not arise from an avoidance of the phonological loop, but from its inefficient use. An alternative account referring to unstable phonological representations in long-term memory is discussed.
