Which term describes the phenomenon when two individuals begin to mirror each other's behavior in a conversation?

The correct term for the phenomenon when two individuals begin to mirror each other's behavior during a conversation is "entrainment." This concept originates from the field of rhythm and synchronization, where it describes how individuals adjust their behaviors, gestures, or speech patterns to become more in sync with one another. Entrainment can occur in various contexts, such as during conversations, musical performances, or even physical interactions, facilitating connection and understanding between the individuals involved.

While terms like sympathy and empathy relate to emotional responses and the ability to understand or share the feelings of another, they do not specifically address the behavioral mirroring aspect. Alignment could suggest a general agreement or harmony between individuals, but it lacks the specificity of the synchronized behaviors that characterize entrainment. Thus, entrainment aptly captures the essence of individuals mirroring each other’s actions in a conversational setting.
