Abstract

The invention discloses a steady-state cognitive response analysis method and device based on a sound stimulation sequence, and the method comprises the steps: respectively generating a test sound sequence and a comparison sound sequence corresponding to sound sequence generation information inputted by a user according to a sound model, respectively playing the test sound sequence and the comparison sound sequence to a tester, acquiring a first brain signal and a second brain signal respectively, analyzing and processing the first brain signal to obtain first analysis information, and analyzing and processing the second brain signal to obtain second analysis information; and performing difference comparison on the first analysis information and the second analysis information according to a difference comparison rule to obtain a steady-state comparison analysis result of the brain steady-state cognitive component. By means of the method, the obtained first brain signal and the second brain signal can be analyzed and processed respectively, then difference comparison is conducted on the first analysis information and the second analysis information which are visually represented, and the accuracy of analyzing the brain steady state cognitive components is greatly improved.

Description

technical field [0001] The present invention relates to the technical field of steady-state cognitive response analysis, in particular to a steady-state cognitive response analysis method and device based on sound stimulation sequences. Background technique [0002] The human body will produce a cognitive response to various information in the natural environment, such as the connection with the objects it sees, and the brain signal will also change accordingly when the human body produces an authentication response. The signal is analyzed. However, the inventors found that the existing cognitive response analysis method has the problem of low analysis response in the process of analyzing brain signals caused by sound stimulation, and it is difficult to analyze the changes of different brain signals caused by different stimuli, that is, An accurate analysis of the variability between different brain signals was not possible. Therefore, the existing technical methods have t...
