Convergent construct validity of the VR-based HMD-CTT. Trails A (tA, left panel) and Trails B (tB, right panel) completion time recorded during the gold-standard pencil-and-paper CTT plotted against the corresponding completion times recorded during HMD-CTT, for YA (blue), MA (orange), and OLD (green) participants. Two OLD datapoints are missing as the participants did not complete the HMD-CTT.*Pearson correlations are shown for YA, MA, OLD and combined (black) groups, and regression lines are plotted for significant correlations. Dimond markers and thick lines adjacent to the axes indicate mean ± SD for YA, MA, and OLD groups. *One OLD participant who could not finish the HMD-CTT Trails B had the slowest Trails A completion time, for both pencil-and-paper (i.e., 170.5 s) and HMD versions (450.2 s). His completion time for the pencil-and-paper Trails B was 327.3 s (this data point was not plotted)
