The present study examined the effect of performance feedback on interval timing. Time production tasks with start-stop procedures were performed in two experiments that consisted of three phases. Experiment 1 investigated whether the feedback effect persisted after it had been withdrawn (learning effect). Participants had to produce 10-seconds intervals in all three phases, but they received the feedback only in the second phase. Participants were randomly assigned to one of four feedback groups (accurate, 80%-feedback, 125%-feedback, no-feedback). Produced interval times shifted according to the feedback in the second and third phases, thus showing the learning effect on interval timing. Experiment 2 examined the generalization effect of feedback with longer target duration in the third phase. The feedback effect was also observed when participants had to produce 30-second intervals in the third phase, suggesting that the feedback effect can be generalized to different intervals. With biological internal clock model, these results are interpreted that feedback affects not only specific temporal representations, but also other representations in the reference memory.
