Abstract: Theory of Object File (OF) is one of important theories which formulate how to build up persisting representation of objects in dynamic situation. Begin with the theory of FIT which firstly refers to the concept of OF, the article reviewed the model of OF and its experimental demonstration. Based on OF theory, some issues as to the underlying characteristics of forming, persisting and updating of OF are discussed. Then, the article introduces theory of Event File developed from OF theory recently. Finally, some suggestions are made regard to some contradictions of research on OF in dynamic temporal-spatial condition such as the core hypothesis of OF, the type of information stored in OF and theirs’ relationship, etc

Key words: temporal-spatial persistence, episodic representation, object file, event file
