From a trivial task of counting objects, the proposal of this work is to present a study on the reactions of the nervous system through visual stimuli to the cognitive system. Our experimental results show that there is a relationship between the cognitive load and pupillary diameter variation, reinforcing the idea that the pupil is a sensitive indicator of mental effort. We believe that pupil diameter measurement can be used as a performance descriptor in cognitive tasks.Acesso RestritoArtigo de evento10.1007/978-3-030-36636-0_15Cognitive countingEye-trackingMental effort
