Illustration of the working memory paradigm. A task cue indicated the stimulus type that had to be remembered on a given trial (i.e., positions or letters), thus allowing for advance implementation of the currently relevant cognitive set. After an instruction delay, which lasted between 4 and 12 s (in steps of 2 s), a series of four stimulus displays was presented. These comprised both spatial positions and letters, but only the cued stimuli had to be attended to. The appropriate sequence had to be maintained for a memory delay of 6 s and was tested by a single probe that required a judgment about the order of two of the stimuli (e.g., “Was the bottom right square immediately followed by the top right square?” or “Was the letter T immediately succeeded by the letter X?” “Yes” is the correct answer in both examples.).
