CONCEPTS AND APPLICATIONS OF EEG-ANALYSIS IN AVIATION PERFORMANCE EVALUATION

Quantitative studies of the human EEG during signal detection, flight simulation and actual flight performance tasks are reviewed here from the perspective of basic animal research on the neurophysiological and functional correlates of relevant rhythmic patterns. Evidence is exam ined which relates distinct EEG frequency changes to psychomotor behav ior, signal processing and intrinsic attentional modulation during com plex performance. Findings indicate that the EEG dan provide a valid a nd objective index for mental effort but, in addition, may reveal task -related cognitive resource allocation, task mastery and task overload .
