(a) g Loadings of each test (RAPM = Raven Advanced Progressive Matrices Test, PMA‐R = inductive reasoning subtests, DAT‐AR = abstract reasoning subtest, PMA‐V = vocabulary subtests, DAT‐VR = verbal reasoning subtest, DAT‐NR = numerical reasoning subtest test, PMA‐S = mental rotation subtest, DAT‐SR = spatial relations subtest and Solid Figures = Rotation of Solid Figures) and DCs for each brain index (GMV = gray matter volume, CSA = cortical surface area and CTh = cortical thickness). (b) Scatterplot between mean of all Dice coefficients and g loadings. [Color figure can be viewed in the online issue, which is available at http://wileyonlinelibrary.com.]
