Evaluation of Decision Confidence in Number Search Tasks Based on EEG

Abstract:
In this paper, we designed a number search task to induce different decision confidence, which replaced decision confidence with task award. In order to increase the role of channel information in decision confidence evaluation, a channel attention module was introduced into the existing model. We tested the performance on the number search dataset and compared it with existing models to verified the superiority of our model. The analysis results of behaviour data and visualization of channel attention, confirmed the success of the experimental design.
