Participants in the treatment condition completed four laboratory sessions: Session 1 (baseline; 4 –5 days prequit), Session 2 (1–2 days postquit), Session 3 (3–5 days postquit), and Session 4 (10 –14 days postquit). Participants in the delayed treatment control condition also attended four sessions spaced over the same intervals, though they did not receive treatment or quit smoking. In addition to the tasks described below, participants completed the PANAS and WSWS questionnaires immediately following smoking assessment.
