Before and after completing their weekly CogMed QM working memory training task, participants will be asked to reflect on their long-term goals for quitting smoking, using guided imagery about future smoking/non-smoking life status as well as open-ended exploration of the perceived advantages and disadvantages of smoking versus quitting. Participants will be informed of the hypothesized role of working memory training as an exercise to help them keep their long-term goals in mind when cravings and temptations arise, and will be encouraged to use the skills they are practicing during the working memory exercise to help them resist temptations to smoke.
