Tracking mental processes in sight translation. Neurobiological determinants of selected eyetracking parameters

The article reviews the author’s research on two selected eyetracking parameters, i.e., spatial saccades and pupil dilation, and their relationship with the mental activity of the translator during sight translation performance. An overview and discussion of the results of studies conducted in recent years show how we can detect particular mental processes involved in translation thanks to the analysis of specific saccadic movements. It also points out the advantages and limitations of pupil dilation in the assessment of the cognitive load. Both eyetracking parameters have been analysed in relation to their neurobiological determinants.
