Table 2 Comparison between test scores (mean ± SD) of older and young (CPT-A/B, BJLO, TMT-A/B, and RCPM)

From: Spatial navigation ability is associated with the assessment of smoothness of driving during changing lanes in older drivers

Test Older Range Young Range p
CPT-A 27.01 ± 3.01 25~30 28.05 ± 1.91 27~30 n.s
CPT-B 20.36 ± 4.92 19~27 27.30 ± 2.10 25~30 p < .001
BJLO 26.82 ± 3.1 23~30 28.20 ± 1.76 26~30 n.s
TMT-A 23.96 ± 10.35 20~59 21.39 ± 4.98 17~30 n.s
TMT-B 57.34 ± 46.73 49~120 42.90 ± 9.98 28~58 p < .05
RCPM 34.67 ± 1.10 30~36 35.00 ± 1.35 33~36 n.s
  1. Comparisons of the distributed value of RMSΔ3 in lane change. The older group took significantly larger of RMSΔ3 in lane change; mean ± SD
  2. n.s not significant, CPT-A/B the Card-Placing Test Part A and Part B, BJLO Benton Judgment of Line Orientation Test, TMT-A/B the Trail Making Test Part A and Part B, RCPM Raven’s Colored Progressive Matrices
