Abstract: The research of auditovisual integration EEG signal has enriched the field of brain cognition. However, most of existing EEG analysis methods are based on linear analysis methods, and require high SNR for data. Being a non-linear analysis method, the recursive quantitative analysis method based on the order recursive plot of phase space reconstruction has a lower noise requirement on the measured signals. It provides a new analysis method for the integration of audiovisual and auditory studies. Through the experiment of design different audiovisual stimulation paradigms, and EEG data of subject are collected under different stimulation paradigms. The phase space reconstruction is used in the preprocessed data to obtain the ordered recursive plot. Taking the Recursive Rate（RR） and deterministic（DET） as analysis parameters of integration effect. The experimental results show that this method can effectively analyze the visual and auditory integration effects from the perspective of nonlinear and it has high accuracy.
