Abstract: “Salience” as a basic thinking model and a way of cognition has received popular concern and vast agreement. In view of cognitive pragmatics, it not only enriches the contents of some main pragmatic conceptions as “intention” and “common ground” but also engenders better interpretation on “egocentrism” which is contributed by cognitive psychologists. This paper, based on social cognitive perspective, seeks for a dialectical and dynamic approach on combining cooperation and egocentrism. Based on the original conception offered by Giora and further illustration by Kecskes on SBUS, we intend to enlarge and deepen the conception and scope of utility of salience so as to propose an alternative term as “propositional salience”, which will form a systematic approach of salience and will better illustrate the mechanism of communication
