加州大学圣塔芭芭拉分校的语言，互动和社会组织（LISO）部门有两个组成部分：跨学科博士学位。重点是研究生可以攻读博士学位，而跨学科人文中心研究焦点小组则负责邀请演讲者进行演讲。博士 重点由传播，教育，语言学和社会学系正式参与。但是，欢迎各学科的教师和研究生参加。LISO的教职员工和研究生在其自然发生的互动环境中进行语言使用和其他交流行为的研究，并特别赞赏这些即时环境对于理解人类行为的重要性以及在这些环境中进行录音以研究人类行为的重要性。LISO的成员研究非正式的对话互动以及教室和911紧急呼叫等机构环境。
The Language, Interaction, and Social Organization (LISO) unit at UC Santa Barbara has two components: an Interdisciplinary Ph.D. Emphasis that graduate students can undertake as part of their doctoral degree, and an Interdisciplinary Humanities Center Research Focus Group that sponsors talks by invited speakers. The Ph.D. Emphasis has formal participation from the Departments of Communication, Education, Linguistics, and Sociology. However, faculty and graduate students from all disciplines are welcome to participate. LISO faculty and graduate students conduct research on language use and other communicative action in their naturally occurring interactional contexts with a special appreciation for the importance of those immediate contexts for understanding human conduct and the need for recordings made within those contexts for studying it. Members of LISO study informal conversational interaction as well as such institutional contexts as classrooms, and 911-Emergency calls. Some members study child language acquisition and socialization-again with a special emphasis on the importance of the local natural contexts of those processes-while others investigate the connection between grammar and interaction and still others examine the connection between language and culture.
