Among healthy individuals, prefrontal recruitment is positively associated with age (Rypma et al., 2005) and negatively associated with performance on neuropsychological measures of cognitive efficiency (Rypma et al., 1999, 2006).
Although time-to-completion scores are typically used to examine aspects of attention and executive function, the difference between the two scores (TMT-B – TMT-A [DIFF B-A]) provides a measure of cognitive efficiency (15).
Although time to completion scores are typically used to examine aspects of attention and executive function (17), the difference between the two scores, TMT-B minus TMT-A (DIFFBA), provides a measure of cognitive efficiency (18).
The MMSE and TMT-A were not sensitive to small changes in over time, and this may be explained by the fact that such neuropsychological tests do not show significant variations over a short observational period compared with tests measuring cognitive flexibility, cognitive efficiency, and memory (18).
NHD may be associated with improved general cognitive efficiency as measured by psychomotor efficiency and attention and working memory.
The results suggest that the balancing mechanisms that mediate differences in low- versus high-demand PFC connectivity are intimately related to individual differences in cognitive efficiency (as measured by DSST).
In order to avoid that preexisting baseline differences among children could prevent from detecting correlations between intervention-related cognitive improvements and their potential neurobiological markers, bivariate correlations were also computed between post-intervention measures of proNGF level and all indices of cognitive efficiency.
Also, the Vai script, a syllabary with more than two hundred characters, offered nothing like the cognitive efficiency that Havelock ascribed to Greek.
Yes, I will take the slowed cognitive efficiency, in favor of protecting his brain.
This insight increasingly influences our understanding of cognitive efficiency [2] [5].
