Abstract: One of the important problems in AI is to study the mode of thinking.The computer offers a new tool for solving this problem.Psychologists,computer scientists and linguists have done a lot of research work on thought and memory,resulting in Hunt's distributed memory model,Schank's theory of conceptual dependency and dynamic memory,Anderson's associative memory model and architecture of cognition.We have started our research work in this field.We are confident that it will have an important prospective application in the future computer.
