Discrete capacity limits in visual working memory.
The amount of information we can actively maintain 'in mind' is very limited. This capacity limitation, known as working memory (WM) capacity, has been of great interest because of its wide scope influence on the variety of intellectual abilities. Recently, there has been an ongoing debate about how this capacity should be best characterized. One viewpoint argues that WM capacity is allocated i...
متن کاملAn assessment of fixed-capacity models of visual working memory.
Visual working memory is often modeled as having a fixed number of slots. We test this model by assessing the receiver operating characteristics (ROC) of participants in a visual-working-memory change-detection task. ROC plots yielded straight lines with a slope of 1.0, a tell-tale characteristic of all-or-none mnemonic representations. Formal model assessment yielded evidence highly consistent...
متن کاملDiscrete-slots models of visual working-memory response times.
Much recent research has aimed to establish whether visual working memory (WM) is better characterized by a limited number of discrete all-or-none slots or by a continuous sharing of memory resources. To date, however, researchers have not considered the response-time (RT) predictions of discrete-slots versus shared-resources models. To complement the past research in this field, we formalize a...

activated portion of the information in permanent memory, which extends beyond the focus of attention to include some automatically activated information (see Fig. 1). When researchers use the term 'working memory', some of them seem to be referring only to the focus of attention, whereas others seem to be referring to all of the temporarily activated information. It is also likely that certain...
متن کاملDiscrete resource allocation in visual working memory.
Are resources in visual working memory allocated in a continuous or a discrete fashion? On one hand, flexible resource models suggest that capacity is determined by a central resource pool that can be flexibly divided such that items of greater complexity receive a larger share of resources. On the other hand, if capacity in working memory is defined in terms of discrete storage "slots," then o...
