Recent theoretical conceptualizations of visual working memory (WM) have begun to emphasize the action-oriented nature of this system. To guide behavior, information stored in WM must be selected and mapped onto task-appropriate responses. Several physiological signals associated with the selection of task-relevant WM content have been identified, but it is unclear whether these signals index unique selection mechanisms. Here, we independently tracked and compared several electrophysiological and oculomotor signals previously linked with the selection of WM content. The data reveal a rich tapestry of functionally and temporally independent signals associated with the selection of visuospatial and visual feature information, as well as the selection of task-appropriate responses. Theoretical models of internal selective attention and WM-guided behavior will need to account for interactions between processes indexed by these signals. |
