Dynamic relationships between stress states and working memory

Selection for vigilance assignments: a review and proposed new direction

“…The broader task engagement factor also relates to superior vigilance (Helton et al 2008, Matthews andCampbell 2009). Consistent with a resource interpretation, the benefits of high energy and task engagement extend to other demanding tasks, including controlled visual search ) and working memory (Matthews and Campbell 2010). Cognitive stress processes associated with higher task engagement, including use of task-focused coping and appraising the task as a challenge, also predict sustained attention (Matthews and Campbell 2009).…”

Time to be smart: Uncovering a complex interplay between intelligence and time perspectives

“…Although there is no clear evidence how positive affect correlates with intelligence tests, many studies show that low stress is beneficial for working memory (Matthews & Campbell, 2010) and executive control (Matthews & Zeidner, 2012), constructs crucial for fluid intelligence (Chuderski, Taraday, Necka & Smolen, 2012). Therefore, one may expect that Past Positive will be associated with low stress in test-taking situations and possibly with better performance on the IQ test.…”

Energetic Arousal and Language

“…For instance, Humphreys and Revelle (1984) noted that in various tasks, the effects of arousal manipulations tended to show up only in the latter stages of an experimental session. Similarly, Matthews and Campbell (2010) found that task engagement was more highly correlated with working memory in posttask measurements. It is possible, then, not only that energy affects performance, as was shown in experimental manipulations (e.g., Revelle et al, 1980) but also that the task has some influence on the level of EA.…”

“…For instance, in a recent article, Matthews and Campbell (2010) tried to establish a dynamic association between stress states and working memory. The authors measured, among other things, a state of task engagement, which integrates energy, motivation, and concentration.…”
