Note. N = 174. All correlations are significant, p < .05. ECB = Everyday Cognition Battery; IR = measure of basic Inductive Reasoning ability; KN = measure of basic Knowledge; HVLT = Hopkins Verbal Learning Test; DM = measure of basic Declarative Memory; WM = measure of basic Working Memory; Mem. = Memory; g = composite variable of basic ability measures; ECBg = composite variable of ECB tests.
