This study investigates word finding difficulties in military meetings during a crisis management exercise in which English is used as a lingua franca (ELF). Multimodal conversation analysis (CA) is used to examine how searching for a next item in a turn-in-progress, i.e., a word search, is attended to via coordination of verbal and embodied conduct. The analysis shows different kinds of word search organizations: searches can be initiated and carried out without recruiting the co-participants’ assistance, co-participation can be invited to varying degrees, and searches can be collaboratively completed without the speaker's visible attempts to solicit assistance. These organizations are illustrative of the institutional and interactional context, namely that the opportunities to invite and manage co-participation via verbal and bodily-visual resources, such as gaze and indexing or iconic gestures, are in some cases more limited than in others. These opportunities are foremost connected to the sequential and sociomaterial environment of word searches and the situated roles enacted by the participants. The study highlights word searches as discrete activities that make linguistic and epistemic discrepancies between the speaker and co-participants relevant and negotiable in the moment-by-moment unfolding of interaction.

本研究调查了在危机管理演习期间军事会议中的单词查找困难，其中英语被用作通用语 (ELF)。多模态对话分析(CA) 用于检查如何通过协调口头和具体行为来处理在交接过程中搜索下一个项目，即单词搜索。分析显示了不同类型的词搜索组织：搜索可以在不招募共同参与者的帮助的情况下启动和执行，可以不同程度地邀请共同参与，并且可以在说话者没有明显尝试寻求帮助的情况下协作完成搜索. 这些组织说明了制度和互动环境，也就是说，通过语言和身体视觉资源（例如凝视和索引或标志性手势）邀请和管理共同参与的机会在某些情况下比在其他情况下更为有限。这些机会最重要的是与单词搜索的顺序和社会物质环境以及参与者所扮演的角色相关。该研究强调单词搜索是离散的活动，使说话者和共同参与者之间的语言和认知差异在互动的时刻展开中具有相关性和可协商性。
