The experience, regarding human body as the medium, working with the means of "behavior or thought", taking the typical character of the interaction of cognition-emotion, is a kind of physiological and mental state which is constructive consecutively, as well as induced when facing to the objects which act on individual being significative. The research on the psychological mechanisms of experience is a effective way to grasp the connotation of experience and realize the function of experience. The psychological mechanisms of experience mainly consists of five parts. Firstly, it needs the presention of the object. Like other psychological phenomena, it essentially reflects the experience also has its corresponding psychological content. Secondly, it needs the construction of meaning. As a subject, people need objects for evoking experience. However, not all objects can make the person produce psychological experience. The world is not as simple, realized things, but as possible formation for human service that presented to us. Therefore, besides object, the other necessary condition is the object must be meaningful to people. Thirdly, it needs the changes of body. The core of it is the reaction of physiological and psychological changement. Fourth, the experience occurs. By the construction of individual meaning, the object will cause the individual corresponding physical and mental changs in the body. when the changes go into the consciousness, which be “aware”, the experience will appear. finally, Finally, with the passage of time, according to the need of the individuality and the society, The experience involves in two basic forms—explicit experience and implicit experience. Explicit experience and implicit experience are not isolated, repel each other, but the dialectical unification between them. On the one hand, they are significantly different each other; On the other hand, they are both mutual penetration and mutual transformation.From the view of the source. on the one hand, the explicit experience and implicit experience are derived from the original individual experience. On the other hand, the original experience appeared in the form of explicit experience or implicit experience, which is decided by s the definition,of timulated object, the strength of experience, individual knowledge and many other factors. From the view of procession, explicit experience and implicit experience operate according to different rules. From the view of the results, the explicit experience and implicit experience transformate each other. The research on experience and its psychological mechanism, is not only the objective requirement of emotional psychology, but the internal need of cognitive psychology for evolution; It is not only the historical development of cultural psychology, but also a way to return to the indigenous psychology.
