Research on the Functional Foreign Linguistics Based on Complex Adaptive System

In order to study the functional system of foreign language linguistics, this paper proposes a new method based on adaptive system from the theory perspective of complex adaptive system, and using different stimulation channels can be stimulate the learning of foreign language. The foreign language learning is stimulated by using different stimulation channels, and through the comparison of the auditory, visual and audio-visual, we can find from its memory preservation effect that the audio-visual perception can obtain the amount of language information, to get the best information acquisition mode. Based on complex adaptive system, foreign language can use as a new scientific concept and methodology, which provides a new research model for the study of foreign language linguistics, making linguistics produce complexity science turn, to be more profound understanding the theoretical objectives of foreign language studies.
