Impaired problem solving, visual spatial processing, memory, and cognitive proficiency are consequences of severe alcoholism.
This suggests that older age does not inevitably preclude cognitive proficiency.
Future studies are needed to further explore the efficiency of test-enhanced learning in relation to individual variation in cognitive proficiency.
Future studies are needed to further explore the efficiency of test-enhanced learning in relation to individual variations in cognitive proficiency.
Only the SLD children, not the ID children, revealed significant differences in the four main factor indexes, and their scores for the additional General Ability Index (GAI) were higher than for the Cognitive Proficiency Index (CPI).
Whereas a substantial number of studies have demonstrated that test-enhanced learning is superior compared to a diversity of other pedagogical methods,45 few studies have investigated its efficiency in relation to individual differences in cognitive proficiency (e.g. working memory46,47).
At present, the OECD reports on and interprets the achievement results of PISA solely as estimates of cognitive proficiency.
Without prior scores the effect of having friends on cognitive proficiency (not learning gains) would be estimated.
The estimation of the causal path between age and cognitive proficiency is problematic because of several factors, such as grade retention, delayed entry, and entry grade acceleration.
Our principal methodological focus is on the use of so-called plausible values that are related to the estimation of an individual's cognitive proficiency (described below).
With regard to the United States, the results presented in OECD (2013b) indicate that it is somewhat of an outlier with regard to the size of the gaps associated with differences in cognitive proficiency, as well as the gradients of cognitive proficiency with respect to various covariates.
