spatial location on repetition benefit effect of visual working memory

Spatial location is a key feature of object representation. It is still unknown how spatial location affects memory representation during the update and consolidation of visual working memory. In this study, the updating change-detection paradigm was used. In Experiment 1, the locations of items were random within a trial and across trials. The results found that the repetition-benefit effect was destroyed when the locations of items in the second frame were different from that in the first frame. The locations of items were fixed in Experiment 2. The results found that even if the locations of items were exchanged with each other, the repetition-benefit effect was not affected. The influence of spatial configuration was excluded in Experiment 3, and the repeated benefit effect disappeared as in Experiment 1.
