Humans perceive new incoming visual signals while simultaneously maintaining consolidated memory representations to guide future actions. Saccadic eye movements constitute a spatial selection mechanism both in vision and in visual working memory — perception and memory are better at the saccade target location than elsewhere in the visual field. Here, we set out to investigate how saccades orchestrate selection in vision and memory simultaneously. We asked observers to hold oriented stimuli in memory for a later memory test and to generate a saccade at varying movement cue delays to an indicated location. Moreover, we presented visual stimuli (i.e., task-relevant orientations vs. task-irrelevant flashes) around the onset of the saccade and investigated whether the automatic presaccadic attention shift in vision interfered with saccadic selection in visual working memory. We found that memory performance was better at the saccade target location than at locations incongruent with the saccade target. This memory advantage at the saccade target location, however, was limited to short movement cue delays. Importantly, the presence of visual stimuli around a saccade interfered with memory performance when the stimuli shared relevant features with the maintained representations in visual memory. Overall, our results show successful saccadic selection in visual working memory despite the presentation of new visual input. However, we observed a conflict when the visual stimulus and the maintained representations shared the same feature dimension. Thus, in our experiments, saccadic selection in visual working memory did not operate independently of ongoing visual processing.
