Performance on each subtest and composite measure on the NIH Toolbox Cognition Battery by age. Scatter plots of the absolute scores (N = 161) for each subtest and composite cognitive measures. Crystallized scores showed poor positive correlations with age, which appears to be driven by the PVT subtest. Fluid scores showed moderate to strong negative correlations with age. DCCS, Dimensional Change Card Sort; ICA, Inhibitory Control & Attention; LSWM, List Sorting Working Memory; ORR, Oral Reading Recognition; PCPS, Pattern Comparison Processing Speed; PSM, Picture Sequence Memory; PVT, Picture Vocabulary Test.
