Table 3

(a) Comparison of behavioral performances on the go/no-go task by aroma group. (b) Comparison of behavioral performances on the go/no-go task by prime subgroup.

(a)

Measures	Lavender		Coconut		Water
	Baseline	Poststress	Baseline	Poststress	Baseline	Poststress
Go (% correct)	99.5 (0.9)	99.6 (0.8)	99.4 (0.8)	99.3 (1.3)	99.3 (1.4)	99.5 (1.2)
No-go (% correct)	84.5 (12.9)	87.5 (11.6)	78.4 (15.5)	81.5 (16.0)	83.7 (13.5)	85.9 (14.4)
Median RT, mean (SD)	366.3 (60.9)	346.9 (44.6)	354.3 (62.2)	334.7 (49.0)	355.2 (67.5)	342.1 (56.7)

SD = standard deviation.
Dependent variables: go = performance on go trials, no-go = performance on no-go trials, and median RT = median reaction time.

	Baseline	Poststress	Baseline	Poststress
Go (% correct)	99.2 (1.3)	99.3 (1.3)	99.6 (0.6)	99.6 (0.9)
No-go (% correct)	81.9 (13.5)	84.3 (14.4)	82.6 (14.8)	85.8 (14.0)
Median RT, mean (SD)^a,b	356.6 (59.6)	333.2 (48.2)	360.5 (66.9)	349.48 (51.0)

SD = standard deviation.
Dependent variables: go = performance on go trials, no-go = performance on no-go trials, and median RT = median reaction time.
