Embodiment Construction

[0037] In order to make the technical problems and technical solutions to be solved by the present invention clearer, the following will describe in detail with reference to the accompanying drawings and specific implementation examples.

[0038] Such as figure 1 As shown, the present invention is based on a method for evaluating concentration of EEG correlation network elasticity, and the specific steps in the implementation case are as follows:

[0039] Step 1. Experimental design and EEG data recording;

[0040] The participants in the experiment included the subjects and the experimenters, and the EEG of the subjects was completely recorded during the experiment. The EEG electrodes were placed using the international 10-20 system. The electrodes on the left and right frontal, parietal, occipital and temporal lobes were: F1, F2, C3, C4, O1, O2, T3 and T4, and the sampling frequency was 500 Hz. At the beginning of the experiment, the subjects remained in a resting state fo...

Abstract

The invention relates to a method for assessing concentration force based on EEG relevance network elasticity. The method comprises the following steps of I, performing experiment design and EEG data recording; II, establishing EEG relevance network; III, calculating the topological characteristics of the network under different state; and IV, drawing a network state elasticity chart, and quantitatively calculating the concentration force. Through the steps, the concentration force is quantitatively assessed from the view of an elasticity recovering mechanism of the attentiveness, the stable-state time entering the concentration state and recovery time for recovering concentration after being subjected to interference are defined, and the method for assessing the concentration force based on the EEG relevance network elasticity is provided. The method disclosed by the invention has systematicness, reliability and early warning properties, the vacancy in the respect of quantitatively assessing the concentration force of a human brain is made up, and the research result can support the assessment of the concentration force and providing of a powerful method, and can be applied to the respects of enterprise recruitment, core task capacity assessment, psychology test and the like.

Description

technical field [0001] The present invention provides a concentration evaluation method based on the elasticity of EEG correlation network, which relates to a method for quantitative evaluation of concentration based on EEG characteristic wave correlation network, which is a cross technology of complex network theory and brain science field. Background technique [0002] Concentration is the core ability for people to study, work and fight. When we are working on a job, we often face such a situation. Some people are immersed in the flow state and enjoy the high-efficiency dividends it brings; some people face the dilemma of hyperfocus and fall into unrealistic imagination for no reason. ; There are also people who are frequently disturbed by trivial matters such as mobile phone information, and it is difficult to continue to focus on the work at hand. With the popularization of small portable electronic devices, mobile phones, iPads, GPS, etc., people are faced with more ...
