For the 120 min period after the second treatment, two-way ANOVA finds a main effect of amphetamine treatment ( F (1,32) = 63.791; p < 0.001), a nearly significant effect of CNO treatment ( F (1,32) = 4.027; p = 0.055), and a significant CNO treatment × amphetamine treatment interaction ( F (1,32) = 6.489; p = 0.017).
