基于脑电技术自我相关信息注意加工机制研究——在军人选拔中的探索应用与前景分析

Investigation of Attention Processing Mechanisms for Self-Relevant Information Based on EEG Technology—Exploring Applications and Prospects in Military Selection

目的:随着国家对心理评估越来越重视,自我相关信息加工优势为军人心理选拔、心理筛查等领域提供了一项重要的理论基础。本研究探讨出生地信息作为自我相关信息的认知加工过程。方法:本研究采用脑电时频域技术,实验选取35名军校学员,自变量为不同相关度城市名称(高、中、低)。结果:在朝向注意中,Delta与Beta2频段三组SRI差异具有统计学意义(p p < 0.05)。结论:SRI的注意加工神经机制在频域结果中差异显著,高SRI幅值高于中、低SRI,且主要在颞叶与额叶分布。

Objective: With increasing national emphasis on psychological assessment, the processing advantage of self-relevant information provides a critical theoretical foundation for areas such as psychological selection and screening among military personnel. This study explores the cognitive processing of birthplace information as a component of self-relevant information. Method: Employing electroencephalography (EEG) in the time-frequency domain, the experiment involved 35 military academy cadets, with the independent variable being the relevance of city names (high, medium, low). Results: In the domain of attention orientation, statistically significant differences were observed in the Delta and Beta2 frequency bands among the three groups of Self-Relevance Index (SRI) (p p < 0.05). Conclusion: The neural mechanisms underlying attention processing of SRI exhibit significant differences in frequency domain results, with high SRI amplitudes surpassing those of medium and low SRI, primarily distributed in the temporal and frontal lobes.
