Figure 1

Rating Results Fear acquisition Day 1. Participants rated their US expectancy for every trial and their fear before and after fear acquisition. Individual representations indicate the mean for each subject. (a) Day 1 mean US expectancy of each group per stimulus. No group differences were found. (b) Day 1 mean US expectancy smokers versus non-smokers. No group differences were found. (c) Day 1 mean fear rating of each group. No group differences were found. (d) Day 1 fear rating smokers versus non-smokers. Following the colour, grey circles represent non-smokers and red triangles represent smokers. Both smokers and non-smokers showed an increased fear rating post acquisition towards the CS + , when compared to pre acquisition. Smokers showed generally increased fear ratings when compared to non-smokers. [***] indicates p < 0.001.
