In Experiment 1, the mean preference rating for the no-go stimuli was comparable in the first and second ratings. One possible cause for the lack of the decrease in preference was that the go/no-go task in Experiment 1 was relatively easy; therefore, it is possible that participants did not need to suppress their response in the go/no-go task. In order to investigate this possibility, the task difficulty in the go/no-go task was increased in Experiment 2 relative to that in Experiment 1. A previous study demonstrated that the shortening of reaction time deadline (i.e., time window to respond) in the go/no-go task increased the task difficulty, which led to the increase in the inhibition necessary to withdraw responses (Benikos et al., 2013). Therefore, in Experiment 2, we used a shorter reaction time deadline to increase the task difficulty in the go/no-go task.
