During extinction, there was a significant main effect of Stimulus F (2, 36) = 5.19, p = 0.01, η 2 = 0.22 and Time, F (1, 18) = 88.30, p < 0.001, η 2 = 0.83, and a marginally significant Stimulus × Time interaction, F (2, 36) = 2.85, p = 0.07, η 2 = 0.14, suggesting that the decrease in FPS differed between the CSs from early to late extinction.
