Increasing Smoking Cessation Success Through Sleep-amplified Memory Consolidation
Trial Parameters
Brief Summary
The goal of this subproject is to examine the hypothesized improvement of treatment with chess-based training and sleep enhancement, both together and on their own, in smokers. Participants will undergo fMRI measurements, sleep monitoring. They will then be assigned to one of the four experimental groups, including high-intensity interval training with or without chess-based training.
