Bivariate correlations revealed that misplacement was positively related to age (r = 0.33, p = 0.001) and %Fat (r = 0.19, p = 0.03), and inversely related to IQ (r = −0.37, p < 0.001). Further, misplacement was negatively associated with dietary lutein + zeaxanthin (r = −0.22, p = 0.02) and serum lutein (r = −0.25, p = 0.005) concentrations. Similarly, dietary and serum beta-carotene were negatively associated with misplacement (r = −0.24, p = 0.01; r = −0.20, p = 0.03). Object-location binding was negatively related to age (r = −0.25, p = 0.007) and positively related to IQ (r = 0.32, p = 0.001). Object-location binding was not associated with %Fat (r = −0.11, p = 0.1), likely due to the decreased range of performance. Additionally, object-location binding was positively associated with dietary lutein + zeaxanthin (r = 0.21, p = 0.02), serum lutein (r = 0.22, p = 0.02), and dietary beta-carotene (r = 0.20, p = 0.03). No other carotenoids were statistically significantly related to relational memory measures in either diet or serum (all p’s > 0.09).
