The study employs a randomized controlled design to follow 300 individuals who smoke cigarettes as they engage in a smoking quit attempt following standard smoking cessation treatment (ST). Participants will be randomized to one of three conditions: (1) ST+ABR; (2) ST+Sham; or (3) ST-only. Participants will complete a self-screener, baseline appointment, 7 weeks of smoking cessation treatment, combined with approach bias retraining (if applicable) in the laboratory (with the quit day scheduled for the 6th session), 2x daily ecological momentary assessments (EMAs) for 4-weeks following their quit day, and 1-, 3-, and 6-month follow-ups in the laboratory.
