An analysis of d′ revealed a significant main effect of Time of Test on recognition sensitivity, F(1,60) = 16.53, p < 0.05, ηp2 = 0.216. Participants were more sensitive in their recognition decisions at post-test (M = 0.55, SD = 0.5) than pre-test (M = 0.37, SD = 0.52), d = 0.34. However, the effect of Group, F(3,60) = 0.49, p > 0.05, ηp2 = 0.02, and the Group × Time of Test interaction, F(3,60) = 1.53, p > 0.05, ηp2 = 0.07, was not significant. The mean recognition sensitivity scores for each experimental group at pre- and post-tests are shown in Figure 4.
