Abstract: Any speech act is not only subjective, but also inter-subjective. The national rhetoric act is a response to the external national rhetoric act as well as an expression of domestic social will. Accordingly, “the national images of foreign countries in the mind of Chinese teenagers” is an important issue that may influence the national image cognition and international relations in future. The relevant studies in the academic circle still remain in the narrations of “individual examples” and “the impression of the author”. With a psychological and experimental “free association” method and weighting statistics, this paper tries to establish an objective analysis model to reconstruct the conceptual structure of the Japan image in teenagers. After testing some students in a middle school in Shanghai, we have following findings: first, the images of Japan, the US and Korea in the patients are positive in general; second, comparatively, the national image of Japan contains more negative information in the patients; third, the important difference between Japan and other countries is that there is a “mutual embedding” phenomenon between Japan and China in cognition. This research probes into the possibility of analyzing the images of countries in Chinese teenagers at the level of f “psychological structure” and provides a certain reference for the rhetoric of national images.
