Correlations between the devaluation effect and key individual differences: Smoking days per week and the three subscales of the BIS Impulsivity Questionnaire

	Devaluation magnitude
	r	p
Smoking days per week	−.03	.80
BIS Motor	−.26	<.05
Nonplanning	−.14	.26
Attention	−.07	.56

Note: N = 64. BIS = Barrett's Impulsivity Scale. The significant correlation between BIS motor impulsivity and devaluation remained significant when the other three individual differences were controlled in partial correlations (see text).
