Keeping aware of the locations of objects while one is moving requires the updating of spatial representations. As long as the objects are visible, attentional tracking is sufficient, but knowing where objects out of view went in relation to one's own body involves an updating of spatial working memory. Here, multiple object tracking was employed to study spatial updating and its neural correla...

in this study, the effect of cognitive load (cl) training on duration and accuracy of bimanual coordination (bc) task was investigated. for this purpose, athletic male students of shiraz university were randomly divided into 4 groups: g1 with low cl, g2 with intermediate cl, g3 with high cl and g4 control. the subjects practiced for 6 weeks, 3 sessions a week, 6 blocks, 12 trials. the subjects ...

Initially described as task-induced deactivations during goal-directed paradigms of high attentional load, the unresolved functionality of default mode regions has long been assumed to interfere with task performance. However, recent evidence suggests a potential default mode network involvement in fulfilling cognitive demands. We tested this hypothesis in a finger opposition paradigm with task...

Parent involvement (PI) in school is associated with more positive academic performance and social competence in children. However, there are inadequacies in current measures of PI and a need for a better understanding of predictors of PI. In this study, measures were obtained from a normative sample of 387 children in kindergarten and first grade from high-risk neighborhoods in 4 different sit...

Although recent neuroimaging studies suggest that prefrontal cortex (PFC) is involved in working memory (WM), the relationship between PFC activity and memory load has not yet been well-described in humans. Here we use functional magnetic resonance imaging (fMRI) to probe PFC activity during a sequential letter task in which memory load was varied in an incremental fashion. In all nine subjects...

Managing task scheduling management in cloud computing is an essential part for the landscape of complex procedure tasks based on various resources a proficient and scalable path. The aim this research to dynamically optimize aforesaid issue scheduling. improvises imperfection algorithm by pursue weighted fair queuing model, which significantly effective compared existing method. A model has be...
