Goal-directed behavior depends on the ability to flexibly change mental representations in working memory (WM). WM has not only storage but also control component. While largely neglected, these control components are essential for goal-directed behaviors as they transform visual representations into codes that can facilitate or ‘work’ to support behavior. Here, we asked whether and how do task demands change WM representations in the brain?
