As for minimal duration required to produce and perceive pitch direction, our results showed that the minimum time required to perceive pitch perception was usually shorter than what is needed to produce pitch direction, similar to the findings reported for Chinese and English listeners (Chen et al., 2017), lending further support to the claim that physical constraints affect speech production than perceptual constraints do on speech perception (Janse, 2003).
although category boundary sharpness increased with duration among both English musicians and non-musicians, English musicians showed a faster increment than nonmusicians, indicating that musical experience draws greater benefits from extra stimulus duration.
