Sometimes More Is Better, and Sometimes Less Is Better: Task Complexity Moderates the Response Time Accuracy Correlation
This study addresses the relationship between item response time and item accuracy (i.e., the response time accuracy correlation, RTAC) in figural matrices tests. The dual processing account of response time effects predicts negative RTACs in tasks that allow for relatively automatic processing and positive RTACs in tasks that require controlled processing. Contrary to these predictions, severa...

(See the article by El Sahly et al, on pages 703–12.) Influenza causes significant morbidity and mortality with an estimated 36 000 attributable deaths in the United States annually [1]. Human immunodefi-ciency virus (HIV) infection, specifically , advanced disease (CD4 count ,200 cells/lL), has been associated with excess morbidity and mortality [2].

متن کاملChronic pain treatment in children and adolescents: less is good, more is sometimes better
BACKGROUND In children with chronic pain, interdisciplinary outpatient and intensive inpatient treatment has been shown to improve pain intensity and disability. However, there are few systematic comparisons of outcomes of the two treatments. The present naturalistic study aimed to compare the clinical presentation and achieved changes at return in three outcome domains (pain intensity, disabil...
متن کاملMore is Sometimes Less: Succinctness in EL
In logics, there are many ways to represent same facts. With respect to both reasoning and cognitive complexity, some representations are significantly less efficient than others. In this paper, we investigate different means of improving the succinctness of TBoxes expressed in the lightweight description logic EL that forms a basis of some large ontologies used in practice. As a measure of siz...
متن کاملOxygen – less is better , more is better ? ?
Altitude training has been employed as a tool for enhancing performance by athletes since the 1964 Mexico Olympics. The cost and impracticality of going to altitude regularly has led to the development of altitude simulation at sea level by creating low oxygen (‘hypoxia’) environments. ‘Altitude’ or ‘hypoxic’ training facilities are now springing up all around the country. The evidence supporti...
