Note: Full Scale IQ (Standard Scores), Digit Span Forward (scaled scores), and Matrix Reasoning (scaled scores) are aggregates of WISC-V and WAIS-IV performances. Figures Weights (scaled scores) is from the WISC-V. Color-Word Condition 3 (scaled scores) is from the D-KEFS. CVLT Total Acquisition (T-score) is an aggregate of CVLT-C and CVLT-II.
