Diâmetro pupilar e fadiga mental em tarefas de controle de tráfego aéreo

Researches point out that the pupil diameter is a sign for fatigue calibration. In this study, we try to analyze how, through a more complex task of air traffic control, the participants will show a bigger pupil diameter than in tasks of easier air traffic control. Likewise, as the theories that go in line with compensatory mechanisms assume, if the job/task requires it, new resources may be provided to continue its execution. The sample had 61 participants, and two variables were manipulated: traffic density on condition many aircrafts and few aircrafts. And the other variable was the time on the task with 5 minute intervals for 2 hours (23 intervals). The dependent variable was the pupil diameter. The results showed that participants who performed the most complex task had bigger pupil diameter. At the same time, they showed that more activity of the participant, major would be the diameter pupilar. Also, the variable TOT (Time Of Task) showed that the pupil diminished, and then it continued increasing due to a generation of new resources.
