摘要：

One fundamental question for understanding how working memory works, is what the manipulation unit of working memory is. The prevalent object-based theory in cognitive research predicts that memory manipulation is performed on the level of objects. Here we instead showed that the basic units of working memory manipulation are Boolean maps, a data structure describing what can be perceived in an instant. We developed four new manipulation tasks and showed that manipulation times only increased when the number of Boolean maps manipulated increased. Increasing the number of orientations manipulated did not induce longer manipulation times, consistent with a key prediction of the Boolean map theory. The results showed that Boolean maps are the manipulation unit of working memory.
