Note. Assessments are listed in the order in which they were completed. CO = carbon monoxide; T1 = Time 1; T2 = Time 2; HR = heart rate; SBP = systolic blood pressure; DBP = diastolic blood pressure; PANAS = Positive and Negative Affect Schedule; HQ = Hunger Questionnaire; HHWQ = Hughes Hatsukami Withdrawal Questionnaire; WSWS = Wisconsin Smoking Withdrawal Scale; SBQ = Subjective Bias Questionnaire; TCQ = 12-item Tobacco Craving Questionnaire; QSU = Brief Questionnaire of Smoking Urges; ST = Two-Letter Search Task; MT = Serial Math Test; DSST = Digit Symbol Substitution Task; RIPT = Rapid Information Processing Task; SSQ = Subjective Stroop Questionnaire; EEG = electroencephalogram.
Order of completion of the Smoking Stroop Task and Picture Probe Task was counterbalanced across participants.
