Two 2 × 2 repeated measures ANOVAs with condition (simulators vs. confessors) as a between subjects factor and test–retest (T1 vs. T2) as a within subjects factor were separately performed on distortion and commission errors. Regarding the distortions rate, the main effect test–retest, and the interaction effect condition by test–retest reached significance, F(1,71) = 6.46, p = 0.013, ηp2 = 0.08, and F(1,71) = 12.06, p = 0.001, ηp2 = 0.14, respectively. By contrast, the main effect of condition was not found to be significant, F(1,71) = 1.68, p = 0.20. Surprisingly, simulators provided more distorted details at T2 than T1, while confessors did not over time, t(35) = 5.50, p < 0.001, d = 1.10, and t(36) = -0.561, p = 0.58, respectively. Unexpectedly, and contrary to our hypothesis (Hp. 3), no significant differences were found between simulators and confessors at T2 on the number of distorted details provided, t(71) = 1.16, p = 0.25, d = 0.27.
