基于行为与ERP的飞行员注意网络功能
Pilot Attention Networks Function Based on Behavior and ERPs
为了探究飞行学员脑功能中注意网络的特点,使34名飞行员(飞行组)与44名普通大学生(对照组)均完成基于Posner和Peterson的模型(警觉、定向和执行控制)、注意网络测试(atentional-network test, ANT)任务,共4个条件。对比两个群体间的行为数据与事件相关电位(event-related potential, ERP)数据差异。基线条件、定向条件和执行控制条件飞行员群体反应均显著快于普通群体,同时定向加工过程飞行员群体显著快于普通群体,脑电(electroencephalography, EEG)结果与行为结果具有一致性。在代表反应的P3振幅飞行员均显著小于普通群体,表明飞行员在完成相同任务时需要消耗的注意资源更少。得到飞行员群体注意网络功能更好的结论,为飞行员脑功能研究提供了行为和脑电方面的依据,也为飞行员的选拔与训练提供客观依据。
In order to investigate the characteristics of attentional networks in the brain function of flight trainees, 34 pilots (flight group) and 44 ordinary college students (control group) completed atentional-network test(ANT) tasks based on Posner and Peterson's model (alerting, orienting, and executive control). There were totally four conditions. Compared the behavioral data and event-related potentia(ERP) data differences between the two groups. The baseline conditions, orientating conditions and executing control conditions all show that pilot population responses significantly faster than general population. At the same time, processing process of pilot population is significantly faster than general population in the directional condition, and the electroencephalography (EEG) results are consistent with the behavioral results. The P3 amplitude representing the reaction of pilots is significantly smaller than that of the general population, indicating that pilots need to consume less attentional resources to complete the same task. The conclusion that the pilot group pays better attention to network function provides behavioral and EEG basis for the study of pilot brain function, as well as objective basis for pilot selection and training.
