Comparative Study on Inducing Effect of Two Kinds of Shape Flash in Pilot Selection by EEG Detection

Objective To compare the differences of two types of EEG flash evoked effect in pilot selection, and to provide evidence for optimizing the effect of EEG pilot selection. Methods A total of 500 high school students aged 17 to 20 were selected to participate in the Air Force pilot selection in 2020 to 2021. Two kinds of flash (arc and round plate) were used for flash evoked selection respectively. There were 250 people in the arc shaped lamp group and 250 people in the round plate shaped lamp group, and the selection effect and difference of the two kinds of different shaped flash lamp were compared. Results In the arc-shaped group, 238 patients (95.2%) had normal EEG photic driving response. There were 12 patients (4.8%) with abnormal EEG, including 6 patients (2.4%) with abnormal photic driving, 2 patients (0.8%) with multiple reaction, 3 patients (1.2%) with fractional reaction, and 1 patient (0.4%) with abnormal EEG wave. There were 237 (94.8%) normal EEG photic driving in the round plate lamp group. There were 13 patients (5.2%) with abnormal EEG, including 5 patients (0.2%) with abnormal photic driving, 3 patients (1.2%) with multiple reaction, 3 patients (1.2%) with fractional reaction, and 2 patients (0.8%) with abnormal EEG wave. There was no significant difference between the eliminate rates (X² = 0.890, P = 1.000). The elimination rate of arc shaped lamp group was 4.8%, and that of round plate shaped lamp group was 5.2%, there was no significant difference between them (X² = 0.042, P = 0.837). Conclusion The evoked effect of two kinds of shaped flash is basically the same.
