With the variability associated with age and verbal IQ controlled, right hippocampal volume emerged as a marginally significant predictor ( p = .07) of open-ended stem fact recall.
With the variability associated with age and verbal IQ controlled, right hippocampal volume emerged as a marginally significant predictor ( p = .07) of open-ended stem fact recall.
The model assessing open-ended self-derivation of integration facts showed a trend in the same direction, but a weaker relation ( p = .11).
After controlling for the variance in task performance explained by age, sex, verbal IQ, and gray-matter volume (medial prefrontal cortex, mPFC, only), we observed relations between right mPFC thickness and memory for information explicitly taught to the children as well as the new information they self-derived; relations with the volume of the right hippocampus approached significance.
