Based on Sacks and Sechegloff 1979, a key idea in conversation analysis is the notion of recipient design, that characterized as the most general principle of conversational interaction. Recipient design refers to the idea that participants in talk design their talk in such a way as to be understood by an interlocutor, in terms of the knowledge that participants assume they share. In line with Sacks and Schegloff’s idea, Arnoff and Miller 2003:437 assert that the main idea behind the analysis of conversation is based on three mechanisms of collaboration from the participants. Those mechanisms are turn-taking, repair organization, and adjacency pairs. Thus, conversation analysis can be used as a mean of studying the interaction among members of spesific speech community by those three mechanisms. Furthermore, this research deals with the analysis of adjacency pairs in term of dispreferred social act structure that will be explained further in the below section. 4. Adjacency Pairs In conversation, it can be noticed that many turns at talk occur as pairs. A greeting is conventionally followed by another greeting, a farewell by a farewell, a question by an answer. Schegloff and Sacks in Liddicoat, 2007:106 called this sorts of paired utterances as adjacency pairs and these adjacency pairs are the basic unit in which sequences in conversation are built. Malmkjaer 2006 states that adjacency pairs or utterance pairs have two pair parts in a sequence or utterances in a conversation; a first and second pair part, with the second being conditionally relevant on the first. In addition, Yule 1996:77 explains further that adjacency pairs are one of the most significant contributions in conversation analysis. It always consist of a first part and second part, produced by different speakers. The utterance of a first part immediately creates an expectation of the utterance of a second part of the same pair. The examples of adjacency pairs can be seen in the following section: A : Is that a new hair style? B : Yeah. It was time for a new look. Yule, 1996:77 From the example above, it can be seen that the first speaker A asks a question to the second sepaker B. The first speaker A anticipates an expected response from the second speaker B. Indeed, the second speaker gives an expected respond to the first speaker. The above example is typically found in the opening sequences of a conversation. There are also the example of adjacency pairs of question - answer sequence, thanking – acceptance response, and request – acceptance response. First Part Second Part A : What time is it? B : About eight-thirty. A : Thank you. B : You’re welcome.
