Differences in the perception of digital information of aviation operators depending on the degree of extraversion

Considers the influence of the degree of extraversion on the perception of digital information by aviation operators. The analysis of the results of solving the Schulte tables by the test subjects on the «NS-Psychotest» hardware complex based on the recording of the eye track, performed using a stationary eye tracking device «RED250mobile eye tracking device» was carried out. While performing the search function, the number of saccadic movements, their amplitude, and the search time for a given digital value were registered. It has been revealed, that introverts during realization eyes search function perform less saccadic movements and spend less time on it than extraverts do. Significant differences have been found during resolving search tasks depending on degree of extraversion. Some interconnections of extension the latent period of the saccade with complication of solving process the cognitive problem were also found. It was found out, that increase in speed of saccadic movements of eyes leads to low efficiency of results of search task execution. Results of conducted research emphasize value of individual approach to medical flight service taking into account psychological features of flight crew in conditions of rapid progress in aviation technologies and means of visualisation of flight information. The obtained data reveal some features of information perception by operators of complex ergatic systems, the study of which in the future will help to maintain the reserves of attention in a continuous stream of incoming data, and thereby reduce the load on the visual analyzer and increase the reliability of professional activities of flight crew.
