Everybody knows that we can only hold a limited number of things in mind simultaneously.  Is this capacity limit due to a limited number of “slots” in working memory or due a limited resource pool that is divided among the items held in mind?  We found evidence for both (Buschman et al, 2011).  Now, Roggeman et al  use computational modeling to provide further evidence for a hybrid model for capacity limits of working memory.
