	Young (n = 17) (Mean ± SD)		Older (n = 17) (Mean ± SD)		F environment (1,29) ES	F age (1,29) ES	F interaction (1,29) ES

MET/VMET Score	2.06 ± 1.34	1.94 ± 1.34	5.07 ± 2.74	4.20 ± 2.01	NS	19.77*** 0.41	NS
MET/VMET total time (min)	9.63 ± 3.67	11.44 ± 2.33	14.25 ± 4.62	15.09 ± 4.47	NS	11.74* 0.29	NS
Navigation efficiency (%)	84.31 ± 14.99	61.03 ± 17.05	68.89 ± 18.76	59.17 ± 17.97	16.21*** 0.36	NS	NS
Total number of strides	76.06 ± 37.14	75.94 ± 53.24	106.78 ± 48.89	111.24 ± 47.85	NS	7.60** 0.19	NS

Due to technical problems two older adults and one young adult did not have their VMET scores. Degrees of freedom for the total number of strides are 1,32
ES, effect size (partial eta square); MET, Multiple Errands Test; NS, non-significant; RW, real world; SD, standard deviation; VE, virtual environment; VMET, virtual MET.
