Error rate (%correct trials) in early and late phases of experiments 1 (A) and 2 (B) across subjects paralleled RT results. The error rate significantly decreased in the late compared with the early phases of experiment 1 [t(15) = 2.905, P = 0.005] and experiment 2 [t(14) = 2.092, P = 0.028]. This suggests that the reported RT findings do not amount to a change in strategy, slowing down responses to be more accurate in the early phase or speeding up in the late phase sacrificing fidelity in finger order, but reflect a learning-related transfer effect. *P < 0.05, **P < 0.01.
