Table 2. Statistical relationship of the test score navigation and item type subscores with demographic and cognitive variables.

Rotation (including items 5–12 with at least one turn); Double (including items 8–9 with two turns); and Full (including items 10–12 with one 180° turn). Partial measures are adjusted for participant age.

Notes. Significance levels: *** = p < .001, ** = p < .01, * = p < .05. Effect sizes are: r = Pearson correlation coefficients, r_s = Spearman’s rho, d = Cohen’s d, ${\eta }_p^2$ is adjusted for participant age, $r_{XY\cdot age}/r_{s_{XY\cdot age}}$ = partial Pearson/ Spearman correlation adjusted for participant age.
