To ascertain the importance of attention in the devaluation effect through response inhibition, we compared the mean devaluation scores between Experiments 1 and 3 using a one-way ANOVA with experiments as a between-participants variable, which indicated that the mean devaluation score was greater in Experiment 1 (M = 3.88, SE = 1.01) than that in Experiment 3 (M = 0.41, SE = 0.84), F(1,56) = 6.86, p = 0.01, ηp2 = 0.11. This result suggests that attention to the stimuli in the go/no-go task facilitate emotional devaluation through response inhibition.
