Notes. The correlation matrix was adjusted for missing data by MPlus. For reaction time measures (i.e., number–letter and Stroop), scores were reversed so that higher values indicate better (faster) performance. NI = numerical-inductive, VD = verbal deductive, B = block, P = parcel; p < .05 for r ≥ .13, and p < .01 for r ≥ .17 given that n = 230.
