Social anxiety assessment method and system based on composite expression processing brain network

Abstract

The invention discloses a social anxiety assessment method and system based on a composite expression processing brain network. The method comprises the steps that S1, a testee wears multi-channel electroencephalogram measurement equipment; s2, carrying out a composite expression stimulation test on the testee, and synchronously collecting electroencephalogram data; s3, preprocessing the electroencephalogram data, and extracting a power value of each frequency point in an alpha frequency band through short-time Fourier transform; s4, quantifying the relationship among the channels according to the power synchronization degree; s5, constructing a composite expression processing brain network according to a weight minimum principle; and S6, extracting brain network nerve indexes so as to evaluate the social anxiety degree. According to the method, the individual social anxiety degree can be objectively evaluated, the problems of post sampling, high subjectivity, allowable social period deviation and the like of a traditional measurement means are effectively avoided, and the method has wide market popularization value and application prospect.

Description

Technical field [0001] The present invention belongs to the field of psychological techniques, relates to a social anxiety assessment method and system based on a complex expression processing brain network. Background [0002] Social anxiety refers to a clear and persistent state of anxiety that an individual exhibits in the course of daily social interactions with others. This group of people exhibits significant, persistent nervousness or fear of being noticed by others when interacting with people, acting in front of people, and being observed or evaluated.
