As in Experiment 1, we excluded the pictures presented in the error trials from the following analysis. The mean proportion of excluded pictures was 0.12 (SE = 0.01). The same ANOVA used in Experiment 1 was used to analyze data of Experiment 2. The resulting analysis revealed a significant main effect of rating phase, F(1,25) = 8.85, p < 0.01, ηp2 = 0.26, but a non-significant effect of stimulus category, F(1,25) = 2.43, p = 0.13, ηp2 = 0.09. As in Experiment 1, the interaction between rating phase and stimulus category was significant in the present experiment, F(1,25) = 13.38, p < 0.01, ηp2 = 0.35. Post hoc simple effects showed that the go stimuli were rated more positively in the second rating than in the first rating, F(1,25) = 16.02, p < 0.01, ηp2 = 0.39, whereas the preference for the no-go stimuli showed no differences between the first and second rating phases, F(1,25) = 2.29, p = 0.14, ηp2 = 0.08. Furthermore, in the second rating task, the no-go stimuli were rated more negatively than the go stimuli, F(1,25) = 7.86, p < 0.01, ηp2 = 0.21. These results clearly replicate the results of Experiment 1, suggesting that the response type in the go/no go task influenced the preference rating in the second rating phase. As in Experiment 1, mean preference ratings for the no-go stimuli did not differ between the no-go first and second rating phases. Thus, the lack of decrease in the preference for the no-go stimuli could not be attributed to the insufficient task difficulty in the go/no-go task because task difficulty in Experiment 2 was greater than that in Experiment 1.
