Yet, the main effect of time was found significant for the commission errors, F(1,72) = 6.20, p = 0.015, ηp2 = 0.08, showing that all participants (i.e., simulators and confessors) reduced the number of commission errors from T1 to T2, t(73) = 2.48, p = 0.01, d = 0.53. No other main or interaction effects were found to be significant on commissions, Fs(1,72) < 1.35, p > 0.25, ηp2 < 0.02, meaning that simulators did not differ from confessors on commission errors at T2 against our expectation (Hp. 4).
