Mean reaction time has been shown in Figure 3. In order to compare the reaction time in Experiment 3 with that in Experiment 1, a one-way ANOVA was conducted with experiments as a between-participant variable. However, the ANOVA did not reach significance, F(1,56) = 2.10, p = 0.15, ηp2 = 0.04. Mean hit and false alarm rates have been shown in Figure 4. In order to compare the task difficulty in Experiment 3 with that in Experiment 1, an ANOVA was conducted on the hit and false alarm rates, with experiments (Experiment 1 vs. Experiment 3) as a between-participant variable. The analysis revealed that the mean hit rate was higher in Experiment 3 than in Experiment 1, F(1,56) = 26.00, p < 0.01, ηp2 = 0.32, whereas the mean false alarm rate did not differ between experiments, F(1,56) = 0.25, p = 0.62, ηp2 = 0.004.
