Abstract This study aims to explore how interbrain synchrony support simulating partners' lexical access during spoken conversation. The research utilized a joint speech production task, in which two participants took turns naming pictures （joint naming） or engaged in single naming. Interbrain synchrony was calculated using EEG-based hyperscanning technology. The results showed that when participants did not name items themselves, their ERPs exhibited a word frequency effect regardless of whether their partner was naming. More importantly, interbrain synchrony in the theta and alpha bands during the joint naming condition were higher than in the single naming condition, and furthermore, theta band interbrain synchrony was related with the word frequency effect. These findings suggest that theta band interbrain synchrony facilitates the simulation of partners’ lexical access during joint speech production.
