Interactants as social members possess many an identity in their social life, but identities should not be assumed as priori to an interaction, instead, they should be understood as being constructed by interactants with social actions in talk-in-interaction or as the outcome of participants' orientation and negotiation. Taking epistemics and deontics into consideration offers us a pathway to probe into interactants' identity construction by analysing the social actions that they accomplish in and through their turns-at-talk. As a single case study of a telephone call between two acquaintances, the present research reveals the moment-by-moment emergence of the identity of expert and that of novice. Specifically, the novice's requesting for information, explicit advice seeking, and troubles telling are unanimously responded to by the expert with solicited and unsolicited advice giving, though the expert also offers solution, makes assessment and so on in this telephone call. This division instantiates the asymmetrical possession of knowledge, displays different deontic authority, and constructs contrasting identities. Furthermore, the (in)congruence between identity status and stance is also investigated to reveal how identity is constructed, negotiated and even rebutted in talk-in-interaction and to reveal the interactants' calibration of the relationship between identity status and identity stance.

作为社会成员的交互者在其社交生活中拥有许多身份，但不应将身份假定为交互的先验，而是应将其理解为是由交互者在谈话中与社交行为一起构造的，或作为交互作用的结果而构造的。参与者的定位和谈判。考虑到认识论和灵修论，为我们提供了一条通过分析交互者在通话中和通过其轮流完成的社会行为来探究其身份建构的途径。作为对两个熟人之间的电话的单个案例研究，本研究揭示了专家和新手身份的瞬间出现。具体来说，新手要求提供信息，寻求明确建议，尽管专家还提供解决方案，进行评估等，但专家都会以征求和不请自来的建议一致地答复和告知故障。该划分实例化了知识的非对称占有，显示了不同的权威，并构造了不同的身份。此外，还研究了身份状态与立场之间的（内在）一致性，以揭示在互动对话中身份是如何构建，协商甚至反驳的，并揭示了交互者对身份状态与身份立场之间关系的校准。显示不同的宗法权威，并构造对比鲜明的身份。此外，还研究了身份状态与立场之间的（内在）一致性，以揭示在互动对话中身份是如何构建，协商甚至反驳的，并揭示了交互者对身份状态与身份立场之间关系的校准。显示不同的宗法权威，并构造对比鲜明的身份。此外，还研究了身份状态与立场之间的（内在）一致性，以揭示在互动对话中身份是如何构建，协商甚至反驳的，并揭示了交互者对身份状态与身份立场之间关系的校准。
