Table 3.

Mean response time as a function of stimulus distance in the target-directed walking task

Distance	Participant group
	Healthy Control a	BPPV b	UVH c
3 m	3.5 (0.38)	3.5 (0.61)	4.7 (0.66)
6 m	6.0 (0.46)	7.0 (1.2)	8.0c (1.6)

Notes: Response times are expressed in seconds; values in parentheses denote the between-subjects standard error of the mean.

^an = 5;

^bn = 4;

^cn = 5.
