44 Finally, taking into consideration that both age and pathology are accounting for cognitive plasticity variance, our third question refers to the relative weights of both independent variables.
Depressive symptoms were not significantly associated with cognitive flexibility (variance of perceived controllability; r =.031, p =.527), Gender was not a significant moderator of any of the reported associations.
Although there was no significant group difference on the index of cognitive flexibility (variance of perceived controllability; p = 0.270), the depressed group reported lower levels of coping effectiveness (F 1, 108) = 45.754, p < 0.001, partial η 2 = 0.298) and a lower ratio of strategy-situation fit (F 1, 108) = 6.273, p = 0.014, partial η 2 = 0.055).
The finding that cognitive development explained variance independent of age [ 12] has to do with individual differences in TOM skills.
Among the cognitive domains, the variance of frontoexecutive function explained by the UACR categories in APOE E4 noncarriers was 0.5% and that of memory in the APOE E4 carriers was 2.2%.
These estimates were compared to the precision achieved by a 31-variable regression model that outperforms current cognitive models on variance-explained criteria.
Descriptive statistics were estimated after stratification for educational level of the mother and a test of whether mean levels of cognitive functioning and variances were different in the low, middle, and high maternal educational groups was conducted.
Despite the augmented frontal perfusion is thought to account for some variance in cognitive outcome after endovascular intervention, the proper neurophysiological substrate determining cognitive improvement, deterioration or stability remains unclear.
First principal component scores explained respectively 74%, 76% and 74% of variance in cognitive test scores at ages 8, 11 and 15 years; these scores were used as the summary cognitive measure for all subsequent analyses.
