What defines the capacity of visual working memory? There is debate over whether visual items are stored in an all-or-none fashion, or whether visual short-term memory is a more continuous and flexible resource. Evidence from change-detection tasks from our lab point towards a discrete style encoding of items. For example, we show this in (this paper) using response time models. A number of ongoing projects in our lab are looking more closely at the specific assumptions of the slots model (e.g., this paper).
