Effects of Nicotine and Nicotine Expectancy on Attentional Bias for Emotional Stimuli

摘要

IntroductionNicotine’s effects on mood are thought to enhance its addictive potential. However, the mechanisms underlying the effects of nicotine on affect regulation have not been reliably demonstrated in human laboratory studies. We investigated the effects of abstinence (experiment one), and nicotine challenge and expectancy (experiment two) on attentional bias towards facial emotional stimuli differing in emotional valence.
