During the last thirty years, Baddeley and Hitch's [4] multi-component model has been widely used as a theoretical reference point in the field of working memory. Nevertheless, recent empirical data are currently supporting new theoretical frameworks which support a more functional view of working memory. In this paper, we propose a review of these theoretical advances and their implications for clinical neuropsychology. Indeed, if the examination of normal and pathological working memory functioning plays an important role in neuropsychology, the diagnostic approach nevertheless relies on the use of a small number of paradigms which moreover could be questioned in the light of these recent models. Current literature supports the use of simplier paradigms which thoroughly control for time parameters. The aim is to improve the assessment of maintenance and processing mechanisms respectively, and their links in order to better understand what causes forgetting in working memory. This way, clinicians should be more able to define the locus of working memory deficits in several pathologies, and thus to improve the relevance of their revalidation methods.
