The Relative Efficiency of Two Strategies For Conducting Cognitive Task Analysis
<p>Cognitive task analysis (CTA) has evolved over the past half century to capture the mental decisions and analysis that experts have learned to implement when solving complex problems. Since expertise is largely automated and nonconscious, a variety of observation and interview strategies have …

Investigating the interrelated roles of pain and cultural factors on cognitive task performance among patients living with vascular dementia
… between pain and cultural factors on cognitive task performance in individuals with Vascular Dementia. Vascular Dementia, a common form of dementia resulting from reduced blood flow to the brain, is characterised by cognitive impairments, executive function deficits, and behavioural …

Oculomotor and electrophysiological markers of cognitive distraction during low-level and complex visual tasks
… metrics could act as markers of cognitive distraction; 2) whether decrements in hazard perception performance caused by secondary cognitive task demand are to some extent due to cognitive load interfering with processes of alerting, orienting, inhibitory control and visual search; …

Stability and variability in perceptual cognition and visual noticing
… summarizes research on both phenomena and on cognitive task performance, identifying variability between individuals in performance across tasks by alternating between literature reviews, descriptive analyses of two multivariate datasets, and theoretical discussion. More specifically, Chapter …

The Effects of Concurrently Performing Balance and Cognitive Tasks Across the Life Span
A dual-task paradigm involving a primary sensorimotor task and a secondary cognitive task was used to examine the effect of age and task difficulty on the relationship between balance and cognition. We investigated twenty healthy children (mean age = 9.0 +/- 0.8), 20 young adults (mean age = 20.1 …

Let's get physical: the dual-task costs of multiple motor responses
Dual-task costs occur when attention is divided among two or more concurrent tasks. Most dual-task studies involve paradigms where participants complete two, concurrent cognitive tasks; in these studies, performance on one or both tasks are slower and/or less accurate. The goal of this study was to …

Effects of sleep deprivation on autonomic nervous system
… to use a computer to study the SD effects on cognitive performance. Sleep deprivation produces negative effects on cognitive performance. Cognitive performance deficits involved reduced ability to pay attention and impairment of the ability to think quickly and not make mistakes. In this …

The chronic effects of concussion on gait
… a history of concussion during single and dual task paradigms. Individuals with (n=28, mean 6.32 years post injury) and without (n=40) a concussion history completed a battery of gait conditions during single and dual-task conditions. Normalized velocity, step length, stride width, number …

Exploration of Sensemaking in the Education of Novices to the Complex Cognitive Work Domain of Air Traffic Control
… business and industry jobs consist primarily of cognitive work; however, current approaches to training may be inadequate for this type of work (Hoffman, Feltovich, Fiore, Klein, & Ziebell, 2009). To try and improve training and education for cognitive work, Klein and Baxter (2006) have proposed …
