Attention bias training evaluation system based on composite expression processing and method thereof

Abstract

The invention belongs to the technical field of attention bias training, and relates to an attention bias training evaluation system based on composite expression processing and a method thereof. Testees in a normal group and a social anxiety group are recruited, and original electroencephalogram signals are collected by using multi-channel electroencephalogram measurement equipment; the average incubation period characteristic of the P100 electroencephalogram component and the average wave amplitude characteristic of the N170 and P300 electroencephalogram components are extracted as nerve indexes, and index level difference tests of a social anxiety group pre-test composite expression stimulation test and a norm composite expression stimulation test as well as a social anxiety group post-test composite expression stimulation test and a norm composite expression stimulation test are carried out, and the effect of attention bias training can be objectively evaluated and optimized. The method can effectively avoid the problems of post sampling, strong subjectivity, allowable social period deviation and the like of the traditional measurement means, has the characteristics of non-invasiveness, safety, high efficiency and low cost, and has wide market application prospects.

Description

technical field [0001] The invention belongs to the technical field of attention bias training, and relates to an attention bias training evaluation system and method based on compound expression processing. Background technique [0002] Attentional Bias Training (ABT) is a systematic training program that changes or corrects individual attention biases. Attention bias training is widely used as a psychological aid method because it is based on computer operations, has low cost, is easy to promote, and has no invasiveness and side effects. [0003] Facial expression is an innate pattern programmed by organisms in evolution, and it is universal and consistent for all human beings. It is the most sensitive emotion generator and display. Composite expressions have high ecological validity and relatively difficult cognition, which can help to expose the differences between socially anxious people and normal people, and can provide insight into and monitor the specificity of the...

Problems solved by technology

[0005] In order to solve the problems of weak targeting and insufficient objectification existing in the current stage of attention-biased training evaluation in the prior art, the present invention proposes an attention-biased training evaluation system and method based on compound expression processing, based on social anxiety According to the state of complex expression processing of the patient and extract the objective EEG representation index, according to the difference in the index level before and after training, scientifically evaluate the effect of attention bias training. The specific technical scheme is as follows:
