Embodiment Construction

[0052] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0053] Such as figure 1 Shown is a kind of intelligence evaluation method of communication disorder of the present invention, comprises the following steps:

[0054] S1: The main tester and the tester wear a multi-channel EEG measurement equipment group. The EEG measurement equipment group is used for collecting EEG signals.

[0055] S2: Collect the subject's resting-state raw EEG signals.

[0056] S3: Synchronously collect the original EEG signals of the subject and the subject during the communication process.

[0057]S4: Perform preprocessing and wavelet transformation on the original EEG signals of the subjects in the resting state and the original EEG signals during the two-person communication, based on the channel data of the temporal lobe area and the parietal lobe area of ​​the two people during the communication process. The...

Abstract

The invention discloses an intelligent evaluation method and evaluation system for communication obstacles. The method comprises the steps: two-person original electroencephalogram signals are synchronously collected by utilizing online multi-channel electroencephalogram equipment when a object is in a conversation communication scene; and theta and alpha frequency band average instantaneous phases of a specific channel per second and an alpha frequency band energy value of a right side Brudman 45 brain region are obtained based on signal preprocessing, wavelet transform and traceability analysis, and the information migration degree and the perception emotional degree are calculated and used for objective evaluation of individual cognitive communication impairment and emotion communication impairment. According to the method, real-time monitoring and dynamic analysis of a communication process are achieved, a double-person synchronous sampling mechanism is constructed, a comprehensive evaluation strategy is formed from two aspects of cognitive disorder and affective disorder, the problems of post-sampling, high subjective degree, social desirability effect, communication disorder population expression deviation and the like of a traditional measurement means are effectively avoided, and the wide market application prospect is achieved.

Description

technical field [0001] The invention relates to the cross field of information science and cognitive neuroscience, in particular to an intelligent evaluation method and evaluation system for communication disorders. Background technique [0002] Communication barrier refers to the phenomenon of communication distortion caused by the lack of cognitive and emotional synchronization between the two parties during the process of information transmission and exchange between people. Most of the existing evaluation methods for communication disorders rely on questionnaires and subjective reports, most of which are post-event evaluations, and their reliability, validity, sensitivity, and specificity are low, and there is a lack of objective and standardized communication obstacle screening tools. Moreover, the evaluation and treatment of communication disorders are closely related. Only with the support of scientific and objective evaluation methods can a targeted solution be forme...
