On the role of working memory in visual attention.
Current cognitive and neural models of visual attention emphasize the role of working memory in biasing attention to task-relevant input. According to these models, the mnemonic maintenance of visual representations automatically creates an attentional template that prioritizes corresponding stimuli for selection. However, the past decade has provided evidence that visual working memory per se ...
متن کاملThe role of working memory in visual selective attention.
The hypothesis that working memory is crucial for reducing distraction by maintaining the prioritization of relevant information was tested in neuroimaging and psychological experiments with humans. Participants performed a selective attention task that required them to ignore distractor faces while holding in working memory a sequence of digits that were in the same order (low memory load) or ...
متن کاملEffects of Cholinergic Enhancement on Visual Stimulation, Spatial Attention, and Spatial Working Memory
We compared behavioral and neural effects of cholinergic enhancement between spatial attention, spatial working memory (WM), and visual control tasks, using fMRI and the anticholinesterase physostigmine. Physostigmine speeded responses nonselectively but increased accuracy selectively for attention. Physostigmine also decreased activations to visual stimulation across all tasks within primary v...
متن کاملThe effects of incentives on visual-spatial working memory in children with attention-deficit/hyperactivity disorder.
Working memory is one of several putative core neurocognitive processes in attention-deficit/hyperactivity disorder (ADHD). The present work seeks to determine whether visual-spatial working memory is sensitive to motivational incentives, a laboratory analogue of behavioral treatment. Participants were 21 children (ages 7-10) with a diagnosis of ADHD-combined type. Participants completed a comp...
متن کاملVisual-spatial attention aids the maintenance of object representations in visual working memory.
Theories have proposed that the maintenance of object representations in visual working memory is aided by a spatial rehearsal mechanism. In this study, we used two different approaches to test the hypothesis that overt and covert visual-spatial attention mechanisms contribute to the maintenance of object representations in visual working memory. First, we tracked observers' eye movements while...
