Reply to: The timing of speech-to-speech synchronization is governed by the P-center

In her comment on our study, the author suggests that the bimodal outcome observed in the speech-to-speech synchronization test (SSS-test) may be a byproduct of the “P-center effect” rather than a reflection of participants’ auditory-motor synchronization abilities. I acknowledge that our previous studies have not sufficiently explored the role of perceptual P-centers in this bimodal outcome, and I agree that this aspect warrants thorough investigation through specifically designed experiments. However, based on the existing evidence, I believe that differences in participants’ auditory-motor abilities provide the most straightforward interpretation of the bimodal distribution. Below, I present several reasons supporting my contention.
