Two hypothesized functions of working memory – coordination (ability to maintain unrelated storage loads during processing) and integration (ability to integrate multiple elements into a relation) – were explored and compared to fluid intelligence. In Experiment 1, 130 participants completed a modified Latin-Square Task (LST) which experimentally added or reduced storage load. Results suggested...

INTRODUCTION The ability to maintain good performance with low cognitive load is an important marker of expertise. Incorporating cognitive load measurements in the context of simulation training may help to inform judgements of competence. This exploratory study investigated relationships between demographic markers of expertise, cognitive load measures, and simulator performance in the context...

OBJECTIVE The aim of this study was to better understand the role played by perceptual load, at both central and peripheral regions of the visual scene, in driving safety. BACKGROUND Attention is a crucial factor in driving safety, and previous laboratory studies suggest that perceptual load is an important factor determining the efficiency of attentional selectivity. Yet, the effects of perc...

We tested how manual exploration with anisotropic loading (Viscosity-Only (negative), Inertia-Only, or Combined-Load) influenced skill transfer to the isolated inertial load. Intact subjects (N=39) performed manual exploration with an anisotropic load before evaluation with prescribed circular movements. Combined-Load resulted in lower error (6.89±3.25%) compared to Inertia-Only (8.40±4.32%) an...

The cognitive load experienced by a person can be used as an index to monitor task performance. Hence, the ability to measure the cognitive load of a person using speech can potentially be very useful, especially in areas such as air traffic control systems. Current research on cognitive load does not provide enough insight into how cognitive load affects the speech spectrum, or the speech prod...

BACKGROUND Molecular genetic studies are revealing an increasing number of cryptic lineages or species, which are highly genetically divergent but apparently cannot be distinguished morphologically. This observation gives rise to three important questions: 1) have these cryptic lineages diverged in phenotypic traits that may not be obvious to humans; 2) when cryptic lineages come into secondary...

We examined the relationship between tonic--a correlate of self-regulatory functioning--and phasic cardiac vagal activity (indexed by heart rate variability; HRV) during a selective attentional task with varying levels of load. Participants detected a target letter among letter strings superimposed on either fearful or neutral face distractors. Letter strings consisted of six target letters und...

To meet the demanding time-to-market requirements in VLSI/ULSI design, the acceleration of verification processes is inevitable. The parallelization of cycle-based simulation at register-transferand gate level is one facet in a series of efforts targeted at this objective. We introduce dlbSIM, a parallel compiled code functional logic simulator that has been developed to run on loosely-coupled ...

The renal response to an oral load of calcium and the renal concentrating ability of spontaneously hypertensive (SH) and normotensive (WKY) rats were examined. The response to calcium loading was similar between SH and WKY animals in terms of urine volume, osmolality and calcium excretion. Compared to WKY controls, the ability of SH rats to concentrate urine during dehydration was decreased. Th...
