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 کاملSudden death and gradual decay in visual working memory.
General Douglas MacArthur remarked that "old soldiers never die; they just fade away." For decades, researchers have concluded that visual working memories, like old soldiers, fade away gradually, becoming progressively less precise as they are retained for longer periods of time. However, these conclusions were based on threshold-estimation procedures in which the complete termination of a mem...
متن کاملReduced representations capacity in visual working memory in trait anxiety.
Neural processes that support individual differences in trait anxiety and the amount of representations in visual-spatial working memory (WM) are currently unclear. We measured the contralateral delay activity (CDA) in a lateralized change detection task to explore this question. Different levels of memory load were varied within each block. Despite their unimpaired behavioral performance, indi...
متن کاملLocation-Unbound Color-Shape Binding Representations in Visual Working Memory.
The mechanism by which nonspatial features, such as color and shape, are bound in visual working memory, and the role of those features' location in their binding, remains unknown. In the current study, I modified a redundancy-gain paradigm to investigate these issues. A set of features was presented in a two-object memory display, followed by a single object probe. Participants judged whether ...
