Summary of modulation analyses

Category	n	Gaze Modulation	Head Modulation	N	Gaze Modulation Index	Head Modulation Index
Blue squares (“head”)	14	0.1 (4.7)	4.4 (10.1)	23	0.05 (0.15)	0.29 (0.39)
Red circles (“gaze”)	62	41.1 (46.4)	−3.1 (10.3)	56	0.25 (0.56)	−0.01 (0.16)
Green diamonds (“both”)	42	16.2 (28.2)	3.7 (13.9)	32	0.00 (0.53)	0.15 (0.46)
Black stars (“neither”)	35	6.6 (9.0)	−2.1 (8.2)	42	0.07 (0.16)	0.04 (0.20)

Gaze modulation (red circles) is significantly different from head modulation (blue squares), P < 0.01 (2 tailed t-test). Gaze modulation (green diamonds) is significantly different from head modulation (green diamonds), P < 0.05 (2-tailed t-test). Gaze modulation (blue squares) is not significantly different from head modulation (blue squares), P > 0.1 (2-tailed t-test). Gaze modulation index (red circles) is NOT significantly different from head modulation index (blue squares), P > 0.7 (2-tailed t-test). Gaze modulation index (green diamonds) is NOT significantly different from head modulation index (green diamonds), P > 0.2 (2-tailed t-test). Gaze modulation index (blue squares) is significantly different from head modulation index (blue squares), P < 0.01 (2-tailed t-test). Values are means ± SD.
