Conversation Analysis in Social Interaction

Conversation analysis (CA) is a systematic study of talk-in-interaction that examines the structures and processes through which participants co-construct social actions. Developed in the 1960s and 1970s, CA has shown that everyday conversation follows organised patterns such as turn-taking, sequence organisation and repair. Turn-taking rules govern how speakers allocate speaking rights, minimising overlap and gaps, while sequence organisation determines how adjacency pairs (for example, question–answer or offer–acceptance) unfold. Repair mechanisms allow participants to detect and resolve problems in speaking, hearing or understanding, thereby sustaining mutual comprehension. By analysing naturally occurring data, CA has revealed the subtle orchestration of verbal and nonverbal cues, such as gaze, gesture and prosody, that coordinate timing and intent. The approach has been applied across diverse contexts—from family interactions to institutional settings such as medical consultations and legal proceedings—highlighting its global significance. Practical applications include improving clinician–patient communication, designing human–computer dialogue systems, informing language pedagogy and enhancing conflict resolution. CA’s emphasis on detailed transcription and empirical rigour underpins its contributions to social science, cognitive psychology and communication technology.

Conversation Analysis in Social Interaction publication trend

The graph below shows the total number of articles in conversation analysis in social interaction across all publications each year (not limited to Nature Index journals).

Technical terms

Turn-taking: The system through which speakers manage the allocation of speaking rights, organising the transition between speakers.

Repair: The practice by which participants address and correct problems in speaking, hearing or understanding to maintain mutual comprehension.

Sequence organisation: The arrangement of actions in pairs or clusters (such as question–answer) that shape the progression of interaction.

Multimodal signal: The integration of verbal and nonverbal cues—such as speech, gesture, gaze and facial expression—that jointly convey meaning in interaction.
