This thesis discusses two important problems concerning the role of one sensory area in higher cognitive processes. First, we show that area V4 mediates both working memory and decision-making. Second, we develop a new hypothesis about the mechanism of attention in area V4.;To study these ...
For example, attention controls sensory processing; top-down signals from prefrontal and parietal cortex strengthen the representation of task-relevant stimuli2,3,4. A similar ‘selection’ mechanism is thought to control the representations held ‘in mind’—in working memory5,6,7,8,9,10. Here...
Working memory capacity is traditionally treated as a unitary construct that can be explained using one cognitive mechanism (e.g., storage, attention control). Several recent studies have, however, demonstrated that multiple mechanisms are needed to explain individual differences in working memory capaci...
Information from preceding trials of cognitive tasks can bias performance in the current trial, a phenomenon referred to as interference. Subjects performing visual working memory tasks exhibit interference in their responses: the recalled target locatio

attention,we can get a deeper understanding of the cognitive control mechanism of WM.Therefore,the present study aimed to examine how WM impacts involuntary attention by manipulating the WM load.Meanwhile,in order to examine the load theory of selective attention,we adopted verbal WM task and ...
The psychological concepts of working memory and attention are widely used in the cognitive and neuroscientific literatures. Perhaps because of the interdisciplinary appeal of these concepts, the same terms are often used to mean very different things. D
Is this the only mechanism by which ST can occur? Three experiments examined ST's impact on expert golf putting, which is not harmed when working memory is reduced but is hurt when attention is allocated to proceduralized processes that normally run outside working memory. Experiment 1 showed ...
