Turn-taking is a type of organization in conversation where participants speak one at a time in alternating turns. In practice, it involves processes for constructing contributions, responding to previous comments, and transitioning to a different speaker, using a variety of linguistic and non-linguistic cues.
While the structure is generally universal, turn-taking conventions vary by culture and community. Conventions vary in many ways, such as how turns are distributed, how transitions are signaled, or how much overlapping is acceptable.
In many contexts, conversation turns are a valuable means to participate in social life and have been subject to competition. It is often thought that turn-taking strategies differ by gender; consequently, turn-taking has been a topic of intense examination in gender studies. While early studies supported gendered stereotypes, such as men interrupting more than women and women talking more than men, recent research has found mixed evidence of gender-specific conversational strategies, and few overarching patterns have emerged.
