a Means of uncorrected sentence-reading, z-string-scanning, and artificial eye pupil data, relative to the horizontal gaze position. b Means from the artificial eye data and predictions from the physical and synthetic functions. c Means of the corrected pupil data during sentence reading (corrected by artificial-eye- and z-string-based synthetic functions) and z-string scanning (corrected by z-string-based synthetic functions). Pupil size in percentage of change was calculated relative to the baseline pupil size
