Time 1: post-initial instruction; time 2: post-smoke for the minimally deprived smokers; time 3: control cue exposure; time 4: pre-smoking cue baseline; time 5: smoking cue exposure. Values in each row with non-overlapping subscripts are significantly different from each other (p < 0.05). For purposes of illustration, untransformed values are presented for magnitude estimation and composite urge ratings. Only contrasts with transformed values are noted. Urge composite means (mean of the composite score of each subject) are not the product of the mean values of urge rating scale#1 and magnitude estimation time 5).
