Intensity of motor movements of head and limbs during sniffing behavior

Time segment	Intensity of movements (centimeters moved by head and/or limbs)		Paired t test
	Type 1	Type 2	t value	p value
After transition
0–0.5 sec	4.17 (0.35)	2.75 (0.31)	5.463	<.01*
0.5–1.0 sec	2.82 (0.35)	1.96 (0.28)	3.687	<.01*
1.0–1.5 sec	2.74 (0.32)	2.01 (0.17)	3.283	<.05*
1.5–2.0 sec	2.79 (0.20)	2.07 (0.21)	8.449	<.001*
Before transition
0–0.5 sec	5.23 (0.62)	2.26 (0.39)	7.161	<.001*
0.5–1.0 sec	3.03 (0.30)	1.73 (0.29)	3.965	<.007*
1.0–1.5 sec	2.77 (0.30)	1.58 (0.16)	2.984	<.05*
1.5–2.0 sec	2.84 (0.28)	1.88 (0.16)	2.633	<.05*

Intensity was quantified as total centimeters moved by head and limbs during each half-second segment. Intensity of head and paw movements during sniffing was higher for transitions with type 1 behavior compared with type 2 behavior (n = 7) (paired samples t test).
