从传统范式到现阶段范式，不同礼貌研究路径在两大争论焦点上持有不同立场：其一，礼貌研究的视角；其二，礼貌现象的解释层面。作为前沿研究成果之一，Long（2016）面向关系工作提出的社会认知路径尝试解决上述争论。该路径侧重交际中人际关系的探讨，对于礼貌研究两大争议的解决具有借鉴意义，但受自身研究背景的局限，未能对人际交往与社会认知过程提出完整的解释。因此，更为完善的人际交往社会认知路径还有待进一步探讨。

From traditional paradigm to current paradigm, different approaches to linguistic politeness take different stances in the following two debates: first, the perspectives of politeness research; second, the explanatory dimensions for politeness phenomena. A social cognitive approach to interpersonal pragmatics that attempted to address the above two debates has emerged in recent years, notably Long’s (2016) social cognitive approach to relational work. It is to be argued that the approach sheds light on the resolution of the debates concerning politeness research. Yet, due to the limitedness of its research background, it may fail to provide a complete explanatory framework for interpersonal interaction and social cognition. Thus, an improved social cognitive approach to interpersonal communication is yet to be developed.
