An almost significant main effect of Response Hand, F (1, 79) = 3.937, MSE = 705.504, p = .051, partial η 2 = .047, reflected shorter right-hand RTs ( M = 403 ms, SD = 53) compared to left-hand RTs ( M = 407 ms, SD = 54).

This interaction reflected the finding that right-hand responses were more accurate when pressing the lower key than when pressing the upper key, t (79) = −2.992, p = .004, d = −0.335 (two-tailed test, while a nonsignificant trend in the opposite direction occurred for left-hand responses, t (79) = 1.019, p = .311, d = −0.114 (two-tailed test).
