Abstract
The human brain is equipped with the ability to form internal replicas of the external reality. The ability to store, maintain, select and reshape these internal replicas in the absence of steady perceptual input is fundamental to guide future actions in the environment. At the core of these cognitive functions lies a versatile cognitive system called the working memory (WM). WM has been defined as a fundamental cognitive medium that enables humans to briefly retain external information in an internally active and accessible state on which attentional operations can be performed when sensory input is temporarily unavailable. The literature supports the hypothesis that a shared attentional system is underlying WM and perception. The general tenet is that WM and sensory processing are part of a unitary neurocognitive system on which selective attention operates similarly. Similar principles of selection are proposed, whether it be in the internal space of WM or the external space of perception. The main goal of the present work was to take the conceptual association between internally and externally guided attention one step further and to investigate how internal representations are precisely selected.
