Abstract: Along with China’s population unceasingly getting older, the problem of “older adults resistance to persuasion” has already become an important social problem. How to persuade older adults is not only a problem which the whole society faces, but also a topic which the field of linguistics needs to carry out research on. This study attempts to explore the illocution of persuasion which targets older adults from the perspective of multimodal pragmatics, therefore it uses the octet of illocutionary acts to carry out the conceptual analysis of “persuasion”. By employing authentic real-life data, this study conducts a situational analysis of persuasion, in order to probe the pragmatic characteristics of persuasion that is directed at older adults, and to examine the responses that they give. It expounds the process of persuasion implementation and its effects, and puts forward three guiding principles and multiple verbal and nonverbal strategies for the communication with older adults. Furthermore, this paper provides effective persuasive reference for domains including selling goods for older adults, legal knowledge education for older adults, and cheating prevention, thus it broadens the range of traditional studies on speech acts and contributes active aging.
