Mean thresholds and p values associated with ANOVA

	Visual heading	Vestibular heading	Coarse direction	Amplitude
Head coordinates	Horizontal (IA) = 2.7°	Horizontal (IA) = 9.3°	IA = 0.079 m/s2	IA = 0.115 m/s2
	Sagittal (DV) = 3.0°	Sagittal (DV) = 12.3°	DV = 0.104 m/s2	DV = 0.121 m/s2
	p = 0.40	p = 0.004	p value <0.001	p = 0.39
World coordinates	EH = 2.7°	EH = 10.7°	EH = 0.087 m/s2	EH = 0.125 m/s2
	EV = 2.9°	EV = 10.8°	EV = 0.095 m/s2	EV = 0.111 m/s2
	p = 0.60	p = 0.94	p = 0.24	p = 0.021
Body orientation	Upright = 2.6°	Upright = 7.5°	Upright = 0.080 m/s2	Upright = 0.121 m/s2
	Side-down = 3.0°	Side-down = 14.4°	Side-down = 0.102 m/s2	Side-down = 0.114 m/s2
	p = 0.009	p < 0.001	p = 0.009	p = 0.95

Columns indicate the different tasks, and rows indicate the mean comparisons, grouped according to columns (head coordinates), rows (world coordinates), and diagonals (body orientation) in Figs. 2, 4, 5, and 7. Bold indicates p < 0.01. Thresholds correspond to the 84% correct level for each task.
