Fig. 6: Linear and ridge regression results reveal the relationship between survey and brain variables, controlling for age, gender, and ethnicity.
From: Mapping computational cognitive profiles of aging to dissociable brain and sociodemographic factors
A Only GnG-PC2 (slow responding) was significantly associated with advanced brain age and reduced scores on the SES & cognitive reserve factor. Other Go/No-Go cognitive profiles were not significantly predicted by the independent variables tested. B All WCST profiles were significantly predicted by the SES and Cognitive reserve factor, particularly WCST-PC1 (well-performing; positive association) and WCST-PC3 (poor-performing + rigid responding; negative association). **Significant based on both linear regression and ridge regression results, *significant based on linear regression results only.
