1 n = 4938. 2 VA = Verbal Ability; EF/PS = Executive Function/Processing Speed; WM/EM = Working Memory/Episodic Memory; Picture Vocab = Picture Vocabulary; Flanker = Flanker Inhibitory Control; List Sort = List Sort Working Memory; Card Sort = Dimensional Change Card Sort; Pattern Comparison = Pattern Comparison Processing Speed; Picture Sequence = Picture Sequence Memory; Oral Reading = Oral Reading Recognition; RAVLT = Rey Auditory Verbal Learning Test (long delay, trial 7 only); Matrix Reasoning = WISC-V Matrix Reasoning; LMT = Little Man Task. For Toolbox-CB measures (Picture Vocab, Flanker, List Sort, Card Sort, Pattern Comparison, Picture Sequence, Oral Reading), uncorrected scores were used in the analyses. For RAVLT, the total correct scores for trial 7, long delay were used in the analyses. For Little Man Task, percentage correct of all 32 presented trials was used in the analyses. For WISC-V Matrix Reasoning, the total scaled score was used in the analyses. 3 Loadings above 0.40 are bolded.
