After every third slide, participants were asked to rate their negative mood, positive mood, and craving to smoke on screen using a computer mouse. The positive mood state question asked “I am feeling happy, joyful, or pleased,” the negative mood state question asked “I am depressed, angry, worried, or frustrated,” and the craving question asked “I am craving a cigarette right now.” Each question presented choices on a five-point scale: (1) strongly disagree, (2) disagree, (3) neutral, (4) agree, and (5) strongly agree. Within each session, four sets of ratings were collected for each slide valence. Participants were instructed to make the ratings based on how they felt at that moment.
