Table 4 Correlation coefficient (r) between T-RCF (i.e., Tablet-based Rey Complex Figure) composite scores (i.e., SPA, PRO, and KIN) with demographic data (i.e., age, education) and conventional scores extracted from the battery of drawing tasks (adjusted for age and education).

  1. Highest correlation for each conventional score is shown in bold. Correlations with age, education, and RCF-copy scores, N = 97; correlations with other scores, N = 35; * p < 0.05; ** p < 0.01; *** p < 0.001; Apoint-biserial correlation with 0 for non-quadrant strategy and 1 for quadrant strategy.
