Path model of Reduced Model III with relationships among age, brain volumes, and cognition. Numbers at paths are path coefficients; three-digit numbers at variable boxes are residuals. See text for model fit indices. LPFC=lateral prefrontal cortex; FWM=prefrontal white matter; Cd=caudate nucleus; HC=hippocampus; VC=visual cortex; PS=processing speed; IC=inhibitory control; WM=working memory; TP=temporal processing; TS=task-switching; Persev=perseverative behavior.
