Inability to suppress salient distractors predicts low visual working memory capacity.
According to contemporary accounts of visual working memory (vWM), the ability to efficiently filter relevant from irrelevant information contributes to an individual's overall vWM capacity. Although there is mounting evidence for this hypothesis, very little is known about the precise filtering mechanism responsible for controlling access to vWM and for differentiating low- and high-capacity i...
متن کاملWorking-memory capacity predicts the executive control of visual search among distractors: the influences of sustained and selective attention.
Variation in working-memory capacity (WMC) predicts individual differences in only some attention-control capabilities. Whereas higher WMC subjects outperform lower WMC subjects in tasks requiring the restraint of prepotent but inappropriate responses, and the constraint of attentional focus to target stimuli against distractors, they do not differ in prototypical visual-search tasks, even thos...
متن کاملFailure of schizophrenia patients to overcome salient distractors during working memory encoding.
BACKGROUND Prior demonstrations of impaired attentional control in schizophrenia focused on conditions in which top-down control is needed to overcome prepotent response tendencies. Attentional control over stimulus processing has received little investigation. Here, we test whether attentional control is impaired during working memory encoding when salient distractors compete with less salient...
متن کاملFrontoparietal tDCS Benefits Visual Working Memory in Older Adults With Low Working Memory Capacity
Working memory (WM) permits maintenance of information over brief delays and is an essential executive function. Unfortunately, WM is subject to age-related decline. Some evidence supports the use of transcranial direct current stimulation (tDCS) to improve visual WM. A gap in knowledge is an understanding of the mechanism characterizing these tDCS linked effects. To address this gap, we compar...

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...
