Dynamic shifts of limited working memory resources in human vision.

Our ability to remember what we have seen is very limited. Most current views characterize this limit as a fixed number of items-only four objects-that can be held in visual working memory. We show that visual memory capacity is not fixed by the number of objects, but rather is a limited resource that is shared out dynamically between all items in the visual scene. This resource can be shifted ...

Bays and Husain (Reports, 8 August 2008, p. 851) reported that human working memory, the limited information currently in mind, reflects resources distributed across all items in an array. In an alternative interpretation, memory is limited to several well-represented items. We argue that this item-limit model fits the extant data better than the distributed-resources model and is more interpre...

Response to Comment on "Dynamic Shifts of Limited Working Memory Resources in Human Vision"

Cowan & Rouder suggest that a modification to the four-slot model of visual working memory fits the available data better than our distributed resource model. However their comparisons of statistical fit are biased in favour of the slot model. Here we compare the predictions of the two models and present further evidence against the division of visual memory into slots.
