English Several models of working memory (WM), the cognitive system devoted to the temporary maintenance of a small amount of
information in view of its treatment, assume that these two functions of storage and processing share a common and limited
resource. However, the predictions issued from these models concerning this resource-sharing remain usually qualitative,
and at which precise extent these functions are affected by their concurrent implementation remains undecided. The aim of
the present study was to quantify this resource sharing by expressing storage and processing performance during a complex
span task in terms of the proportion of the highest level of performance each participant was able to reach (i.e., their span) in
each component when performed in isolation. Two experiments demonstrated that, despite substantial dual-task decrements,
participants managed to preserve half or more of their best performance in both components, testifying for a remarkable
robustness of the human cognitive system. The implications of these results for the main WM models are discussed.
