(a) CS responses during day 2 (retrieval) reveal a context*smoking status (non-smoking vs smoking participants) interaction measured as skin conductance responses (SCRs), (b) subjective fear and (c) US expectancy. (d) During memory retrieval on day 2, smokers show less contextual inhibition of SCRs (CS+: t(346)=3.07, p=0.002; CS−: t(346)=1.54, p=0.14), (e) subjective fear (CS+: t(346)=3.04, p=0.003; CS−: t(346)=3.76, p<0.001) and (f) US expectancy (CS+: t(346)=2.56, p=0.012; CS−: t(346)=2.46, p=0.015). *=p<0.05; **=p<0.01; ***p<0.001. Error bars represent the standard error of the mean.
