Subjective time can be different from physical time because of the surrounding contexts or what senses we use (Bueti, 2011). Motor, for example, has different timing mechanisms as sensory timing (Tsao et al., 2022). In the perception-action loop, motor timing is coupled with multisensory timing and feedback. How we incorporate different timing and feedback remains controversial (Repp & Su, 2013). We conducted two experiments on duration reproduction, manipulating delay adaptation and accuracy feedback. Experiment 1 compared reproduced durations with 150-ms delayed visual feedback and no-delayed visual feedback, which showed that after adaptation, participants implicitly incorporated 60% of the delay into their reproduction. And without accurate feedback, the duration was overestimated by 10%. Experiment 2 compared with and without accurate feedback after the reproduction, which revealed that without accurate feedback also inflated the estimate by about 10%, both for the sub-second and super-second durations, consistent with the finding of Experiment 1. Our findings suggest that sensorimotor timing is influenced by the integration of motor timing and multisensory timing and the attentional sharing between action and perception. Attention to action, even if it is time-related, may divert attention away from the timing, causing some inflation in the reproduction, when the accuracy feedback is absent.
