Abstract: he study of information process in discourse reading is a hot point in discourse psychology and other related researches. Recently, dynamic text comprehension view and computational model of discourse has been more and more popular. Compared to previous discourse theories, dynamic text comprehension view integrates the on-line process and off-line representation in reading course and the correlation between each other. It also tries to capture the activation fluctuation of all text concepts in the whole reading cycles. The method of using computational model to investigate discourse reading differs from other methods recording subjects’ reading responses. The computer programme simulates information activation of readers and the outcome after reading. The simulation data is consistent with the result of behavior studies

Key words: text reading, dynamic text comprehension view, landscape model, computer simulation
