Background: Overall, there is growing consensus that working memory (WM) should be routinely assessed in individuals with aphasia as it can contribute significantly to their level of language impairment and be an important factor in treatment planning. However, there is still no consensus in the field as to which tasks should be used to assess WM in aphasia. The two main alternatives are adapte...

This study investigated the interaction between two executive function processes, inhibition and updating, through analyses of behavioral, neurophysiological, and effective connectivity metrics. Although, many studies have focused on behavioral effects of executive function processes individually, few studies have examined the dynamic causal interactions between these two functions. A total of ...

In working memory (WM) span tests participants have to maintain to-be-remembered information while processing other, potentially distracting, information. Previous studies have shown that WM span scores are greater when span lists start with a long processing task and end with a short processing task than when these processing tasks are presented in the reverse order (e.g., Towse, Hitch, & Hutt...

Fluid intelligence (gF) and working memory (WM) span predict success in demanding cognitive situations. Recent studies show that much of the variance in gF and WM span is shared, suggesting common neural mechanisms. This study provides a direct investigation of the degree to which shared variance in gF and WM span can be explained by neural mechanisms of interference control. The authors measur...

Learning of supra-span sequences was assessed in a densely amnesic individual (SJ) who suffers from a substantial circumscribed bilateral lesion to the hippocampus. SJ's ability to lay down information originating from repetitive memory recall episodes was assessed using Hebb's supra-span procedure. After assessment of short-term memory span, 25 sequences of span +1 items were presented to SJ f...

A latent-variable study examined whether verbal and visuo-spatial working-memory (WM) capacity measures reflect a primarily domain-general construct by testing 236 participants in 3 span tests each of verbal WM, visuo-spatial WM, verbal short-term memory (STM), and visuo-spatial STM, as well as in tests of verbal and spatial reasoning and general fluid intelligence (Gf). Confirmatory factor ana...

Working memory (WM) usually refers to a cognitive system devoted to the simultaneous maintenance and processing of information which plays a crucial role in high-level cognition. Recently, Barrouillet and collaborators showed the importance of controlling the time course of cognitive activities to assess WM capacities. Therefore, they developed a new paradigm to systematically explore the funct...

A common cause of road traffic incidents is driver distraction, which can occur when the driver’s attention engaged in a concurrent secondary task. However, relationship between cognitive demands, individual differences working memory capacity and driving performance has received little research attention. Using fixed-base simulator, aim this study was to use combination self-report, functional...

Cloud computing depends on sharing of assets to accomplish intelligibility and economies of scale, like a utility over a network. In this various types of job scheduling and load balancing approaches has been used for this purpose. Various tasks on cloud have to be allocated to different resources for prevention of slow computation process at cloud. In the previous work various algorithms and o...
