Structured Representations in Visual Working Memory
How much visual information can we hold in mind at once? A large body of research has attempted to quantify the capacity of visual working memory by focusing on how many individual objects or visual features can be actively maintained in memory. This thesis presents a novel theoretical framework for understanding working memory capacity, suggesting that our memory representations are complex an...
متن کاملModeling Continuous Representations in Visual Working Memory
Visual working memory (VWM) is a crucial part of our cognitive system. Currently there is an active debate how the apparent limitations of VWM should be described. Limited-slot and flexible-resource theories are discussed, but so far the temporal dynamics of representations stored in VWM are not fully understood. In this paper we present data that supports the notion of dynamic VWM contents wit...
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...
متن کاملDiscrete 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 کاملDiscrete Representations in Working Memory: A Hypothesis and Computational Investigations
We present a novel hypothesis concerning the nature and development of working memory representations and some initial computational investigations of this hypothesis. Working memory refers to the active maintenance of information in the service of complex cognition, such as language comprehension, spatial thinking, and problem solving (Miyake & Shah, 1999). We propose that the unique demands p...
