Table 2. Startle potentiation by threat type, task time, and smoking group.

	Baseline			Anticipation			After Consumption
	Overall	U	P	Overall	U	P	Overall	U	P
Deprived Smokers	20.0 (3.2)	19.9 (3.5)	20.2 (3.9)	9.1* (2.4)	8.2 (2.8)	10.0 (2.9)	6.1 (2.2)	7.2 (2.6)	5.0 (2.7)

Note.

Means and standard errors for startle potentiation by threat type and task time adjusted for the interactive between-subject regressor for general startle reactivity (mean centered) for the entire final sample (N=108). U = Unpredictable shock; P = Predictable shock; Overall = (unpredictable shock + predictable shock)/2.

^*Denotes the significant effect (p < .05) of the planned contrast for Anticipation (anticipation of smoking vs. baseline).
