Conversation Analysis

Definition:

Conversation analysis (CA) is a methodology for rigorously examining the sequential structure of naturally occurring talk-in-interaction, developed by sociologists Harvey Sacks, Emanuel Schegloff, and Gail Jefferson from the late 1960s as a branch of ethnomethodology. CA treats conversation as a social institution with its own structural organization—turn-taking, repair, sequentiality, preference organization—which participants coordinate in real time through social action rather than pre-planned rule-following. In SLA, CA-informed research (CA-SLA) examines how L2 learners participate in interactional sequences, how their linguistic resources constrain and enable interactional competence, and how conversation itself functions as a site of language acquisition—not just a context in which already-acquired language is used.

In-Depth Explanation

Core CA concepts:

1. Turn-taking:

Sacks, Schegloff & Jefferson (1974) proposed a formal model of turn-taking in conversation: speakers project completion points (Transition Relevance Places, TRPs) through grammatical, intonational, and prosodic cues; at TRPs, the next speaker may self-select or the current speaker may select (allocate turns through gaze, address terms, or question design). Turn-taking organization is remarkably universal in human conversation, with cross-linguistic variations in overlap toleration, silence interpretation, and floor-holding norms.

2. Adjacency pairs:

Many conversational sequences are organized in paired turns: question-answer, greeting-greeting, offer-acceptance/declination, invitation-acceptance/refusal. The first pair part (FPP) sets up a conditional relevance for the second pair part (SPP). The absence of an SPP is itself sequentially meaningful (noticeable silence, implying something has gone wrong).

3. Preference organization:

Not all SPPs are equally likely. “Preferred” SPPs follow from the FPP without delay or hedging (a question is preferably answered; an invitation preferably accepted). “Dispreferred” SPPs — rejections, declinations, disagreements — are typically marked by delay, preface, account, or mitigation. Japanese has particularly elaborate dispreferred-SPP structures: ちょっと… (chotto…) is a canonical dispreferred SPP marker (hedge + trailing ellipsis indicating refusal without explicit statement).

4. Repair:

When there is trouble in talk — mishearing, misunderstanding, an error, or perceived impropriety — speakers engage in repair sequences. Self-initiated self-repair (speaker corrects themselves) and other-initiated self-repair (interlocutor signals trouble, prompts repair from speaker) are different sequences with different social meanings. Other-initiated other-repair (interlocutor provides the correction) is generally face-threatening in peer interaction. Repair organization in L2 interaction has been studied extensively — OCF types (recasts, elicitation) can be analyzed as repair initiators.

5. Sequential organization:

CA treats sequence rather than sentence as the basic unit of talk. The meaning and function of a turn derives substantially from its sequential position — what came before and what it makes conditionally relevant next.

CA-SLA interface:

Heritage and Atkinson (1984) and later Markee (2000), Kasper (2004), and Gardner & Wagner (2004) applied CA to SLA questions:

How do L2 speakers manage turns and sequence — and what happens when they fail to project TRPs correctly?
How do L2 speakers initiate and respond to repair — and how do these repair sequences function in both acquisition and communication?
Can CA provide evidence for acquisition taking place within an interactional sequence? Markee’s “learning-as-process” CA work examines moments of explicit vocabulary uptake in conversation.
How does CA document interactional competence — the ability to participate appropriately in conversational sequences — as distinct from linguistic competence?

Japanese conversation structure:

Japanese presents several distinctive conversational patterns that CA analysis has illuminated:

Backchannel (aizuchi): The Japanese backchannel system (うん, そう, なるほど, へえ, ほんとうに) is more frequent and sequentially complex than English backchanneling. Japanese aizuchi do not yield the floor but actively co-produce the narrative — they confirm ongoing engagement and comprehension. L2 Japanese speakers often produce insufficient or misplaced aizuchi, disrupting interactional flow.
ちょっと… as dispreferred: The canonical elliptical refusal routine (ちょっと… + trailing silence/tone) is analyzable as a sequentially organized dispreferred SPP that native speakers recognize immediately; L2 speakers may miss this pattern or produce over-explicit refusals that are pragmatically marked.
Sentence-final particles as sequential resources: ね (ne) seeks agreement or confirmation; よ (yo) marks new information delivery to the interlocutor. These particles organize both sequential position (what they make relevant next) and epistemic stance (what the speaker presupposes about shared knowledge).
Silence use: Japanese conversational silence is interpreted differently from English silence — in Japanese interaction, longer pauses within a turn are more tolerated; inter-turn silence following a dispreferred-SPP setup can be the dispreferred SPP itself.

History

1964–1975: Sacks’s UCLA lectures — foundational CA development.
1974: Sacks, Schegloff & Jefferson — “A Simplest Systematics for the Organization of Turn-Taking for Conversation” — canonical CA paper.
1984: Heritage & Atkinson — Structures of Social Action — foundational CA edited volume.
2000: Markee — Conversation Analysis applied to L2 classroom discourse.
2004: Kasper — argues CA is more appropriate than psycholinguistic models for L2 pragmatics research.
2004: Gardner & Wagner — Second Language Conversations — CA-SLA edited volume.
2010–present: CA-SLA research examines L2 peer interaction, service encounters, institutional talk, and online communication.

Common Misconceptions

“CA studies written language and texts.” CA is fundamentally a spoken-interaction methodology. It analyzes real-time, naturally occurring talk using audio/video recordings and transcription systems (Jefferson notation). Written text analysis is a related field (Conversation Analysis of written texts) but not original CA.

“CA and discourse analysis are the same thing.” CA focuses on sequential organization of conversational turns in naturally occurring data; discourse analysis (in its broader SLA senses) encompasses a wider range of approaches, including text cohesion, coherence, and genre analysis. CA is one methodology within the broad field of discourse analysis.

“CA is only descriptive, not acquisitional.” While CA-SLA was initially criticized for being descriptive rather than acquisitional theory, contemporary CA-SLA argues that conversational interaction is constitutive of acquisition (not just a context where acquisition is applied) — and that CA can document learning processes in situ.

Criticisms

CA’s explanatory scope for SLA is contested. Many SLA researchers argue that CA describes interaction but does not account for the cognitive processes underpinning language acquisition — it may be better suited to studying interactional competence than SLA as traditionally defined.
CA’s insistence on naturally occurring data makes it resistant to experimental designs that underpin much SLA research.
The relationship between CA-documented interactional patterns and L2 acquisition outcomes has been difficult to demonstrate empirically.

Social Media Sentiment

CA is rarely visible in popular language learning discussions, but its insights are practically relevant: experienced language learners and polyglots often intuitively describe CA dynamics — “I learned when to not speak in Japanese,” “I figured out aizuchi by watching how Japanese people react when I don’t use it.” Japanese learner communities discuss the social awkwardness of missing aizuchi, failing to use ちょっと… appropriately, and mismanaging silence — all CA-analyzable phenomena.

Practical Application

Observe Japanese aizuchi patterns: Specifically notice うん, そう, なるほど, ほんとうに timing and density in Japanese media with natural conversation. Practice producing aizuchi at appropriate intervals in listening practice.
Analyze dispreferred SPPs in media: Find scenes in Japanese drama or variety shows where someone declines (a request, invitation, or offer) and analyze how the refusal is constructed: ちょっと…, うーん, そうですね… trailing into a hedge. These are sequentially organized dispreferred SPPs.
Practice repair sequences: In language exchange, practice both initiating repair (もう一度おっしゃっていただけますか?) and responding to it. Observe how native speakers repair in your input.
Notice turn-completion signals: Study how Japanese speakers signal TRPs through prosodic/intonational patterns — rising tone, ne/yo particle use, completion clauses — to improve your turn-taking timing.
