本文以自然言谈互动视频为语料,采纳系统功能多模态话语分析视角,提出“研究言语—手势拒绝中模态互动的三分模式”,从物理时间､认知识解和符号融合三个维度考察儿童言语—手势拒绝中的模态互动｡研究发现:儿童在会话时序上模态共现优先,意象映射以过程映射优先,而模态协同则表现为强化— 互补平衡｡这种物理､认知和符号上的模态互动策略是语料儿童实施言语—手势拒绝的典型路径,体现其综合的言语—手势互动交际能力｡

This paper utilizes videos of naturally occurring interaction as its corpus and, by adopting a Systemic Functional multimodal discursive analytic perspective, proposes a tripartite model for studying the modal interaction in verbal gestural refusals. It thoroughly examines the modal interactional characteristics of children’s verbal gestural refusals from the three dimensions of physical time, cognitive mapping, and semiotic fusion. It reveals that children under examination demonstrate a preference for modal cooccurrence in temporal conversational sequences, prioritize transitivity mapping in iconic projection, and exhibit a balanced form of reinforcement and complementarity in modal integration. The strategy of cross modal interaction in physical, cognitive, and semiotic dimensions represents a typical pathway for children in conducting verbal gestural refusals, showcasing the interactive communicative competence of Mandarin children in verbal gestural interactions.
