High-arousal cigarette graphic warning labels (GWLs) appear to be less efficacious than low-arousal GWLs. The high emotional reaction that high-arousal GWLs elicit wanes over time. Baseline amygdala response negatively predicts efficacy of high-arousal GWLs and positively predicts efficacy of low-arousal GWLs. High emotional arousal may not be required for sustained GWL efficacy.
