[The resistance to information noise of flight personnel engaged in expert tasks].

The purpose of the present investigation was to study mental activities of the flying personnel exposed to information noise. The test subjects were presented a black-and-red table and noise signals close to useful signals. They had to find the necessary figures and to discriminate between useful and noise signals. In terms of noise resistance three groups of test subjects were identified: Group 1 (54%) showed no changes, Group 2 (10%) showed a slight improvement, and Group 3 (36%) showed a degradation of mental activities. Several test subjects from Group 3 (9%) displayed complete disorder of their mental activities which led to their failure and refusal to work. These observations can be used in psychological expertise of the flying personnel.
