For GEE modeling, the non-training group serves as the reference control. No group-time interaction terms were significant for any of the tests. Results reflect the mean difference in fully corrected T-scores between groups for each respective test. Standardized scores have a mean of 50 with standard deviation of 10, and scores are adjusted for age, gender, race/ethnicity, and educational attainment (see manuscript text for additional information and references). All available scores were incorporated from both groups (non-training group, n = 29 participants; training group, n = 23 participants)
