Abstract [en]

Working memory processing and maintenance components are supported by a fronto-parietal network that is largely similar, yet subtly different, for signed and speech-based languages. In the present study, we investigated for the first time modality-specific differences in the neural correlates of three different varieties of working memory processing (semantic, phonological and orthographic) in 11 deaf early users of Swedish Sign Language and 19 hearing native Swedish speakers using a picture-based 2-back fMRI paradigm. Contrasts between each of the processing levels and a 2-back, picture-based but non-linguistic baseline condition activated distinct networks between groups. In particular, the two groups activated only partially overlapping networks in regions previously associated with the three different kinds of processing. This suggests that the mechanisms supporting different varieties of working memory processing differ at least partially between modalities.
