This study investigated social controllability in nicotine-dependent individuals using fMRI. Computational modeling revealed smokers underestimated their influence and reported less control compared to non-smokers. Smokers showed reduced vmPFC tracking of projected choice values and impaired midbrain computation of social prediction errors, indicating deficits in estimating personal influence in social contexts.
