Note. Above are adjusted means, standard errors, and measure of effect size. ss = scaled score (mean 10, standard deviation 3); MOANS = Mayo Older American Normative Studies (mean 10, standard deviation 3); WMS-III = Wechsler Memory Scale, Third Edition; LM = Logical Memory I (Immediate recall) and II (Delayed recall); VR = Visual Reproduction I (Immediate recall) and II (Delayed recall); LOT = Learning Over Trials; TMT = Trail Making Test (Part A and Part B); DKEFS = Delis-Kaplan Executive Function System; Rey-O = Rey-Osterreith Complex Figure Test; VOSP = Visual Object and Space Perception
