Abstract: In order to improve the efficiency of identifying information processing levels of controllers,and help to improve the safety level of air traffic control operation,based on the principle of performance test,a test was designed to analyze the information processing level of controllers on the basis of analyzing the information processing process of air traffic control work.According to the SDT,the sensitivity index d and the bias index β were used to identify the information processing levels of controllers.The classification of controllers was analyzed by cluster analysis through examples and the effects of nervous system characteristics on both d and β were analyzed by regression analysis.The results show that d and β are the effective identification index of information processing ability and the effective identification index of information processing bias respectively,that the information processing level of controllers can be classified into three categories,and that the strength and flexibility of controllers can positively predict the information processing ability,and the balance can negatively predict the information processing bias.

Key words: controllers, information processing level, nervous system characteristics, signal detection theory(SDT), sensitivity, tendentiousness
