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

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

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
