Abstract

In this study, we examine the influence of the train radio communication system, which is not directly related to the train drivers' duties, on their task performances. In the experiment, participants performed auditory and visual dual task while not paying attention to the radio messages being transmitted. After the experiment, they had to complete a recognition task relating to the train radio system, which they were not previously informed about.<br>We found that the participant's reaction time for visual targets was longer when more important messages were transmitted on the train radio, as compared to the case where less important messages were transmitted. In contrast, in the recognition task, train drivers recognized the station names presented in the more important radio messages more often than in the less important ones. The results reveal that train drivers display an attentional bias due to which they can not ignored to the more important radio messages, and a memory characteristic by which they automatically retain the necessary operating information. Therefore, it seems reasonable to conclude that train drivers possess the necessary characteristics with which they can operate a train efficiently.
