At present, many scientific experiments are carried out in extreme conditions. Pilots need to perform high-intensity tasks for a long time. Human error is an essential factor affecting mission execution. To deeply study the physiological characteristics of different erroneous states consciousness, we used improved double-choice Oddball paradigm collect brain electrophysiological signals volunteers and pilots missions analyze event-related potential (ERP), time-frequency, function spectrum, extracting EEG indicators sensitive awareness. The results showed that, 300∼500 ms time window, awareness type was correlated with Pe amplitude. Meanwhile, time-frequency functional spectrum analysis that amplitude aware errors α-ERS oscillation, spectral density α-band, uncertain were more prominent than unaware errors. same sensitivity flight as ground volunteer experiment, characteristic value higher participants. We analyzed determined differences when have on flight. This provides theoretical guidance follow-up research intervention measures against determines target point positioning.
