Group Cognition and Conformity under the Influence of Network Public Opinion Based on EEG Testing Technology

Zuowei Zhao


After the 21st century, emergencies gradually increase, which affects the social stability and security. With the rapid development of network information, the network public opinion has a certain influence on emergencies. This paper uses EEG testing technology, adds the options that can be selected in turn based on group interaction platform and virtual context story, and analyzes the effects of the number of options on individual cognition and conformity. The results show that there was a certain mapping relationship between EEG power and emotional arousal degree, the situation has significant effect on the change of EEG power, and the EEG power induced by emergent situation is significantly higher than that induced by daily situation. As the number of options increases, the time-consuming of cognitive tasks decreases and the two are negatively correlated. In the same way, the cognitive level also decreases, which is negatively correlated with the number of options. Cognitive level is the intermediary variable of the number of options and conformity. As the number of options increases, the probability of conformity decreases, but there are certain fluctuations, which results from an increase in the amount of information, scattered options and some people's maverick. At the same time, when options are increased, the increased options will be lower in cost and cognition than those already provided, resulting in a reduction in the impact on conformity ratio changes.
