Total screen attention is the cumulated duration of fixations in seconds that are considered in the statistical analysis. Eye-tracking data accuracy is the Euclidean distance of gaze estimates and target location, whereas eye-tracking data precision is the Euclidean distance of gaze estimate coordinates per target location in a postdoc, six-point calibration. Eye-tracking available data are the cumulated duration of identified fixations by total duration of investigated scenes in percent
