Pupil metrics across different sentence durations in Experiment 2.

Baseline-corrected pupil traces measured in Exp.2 across different duration bins, aligned from the sentence onset (top) or from the response prompt (bottom). Longer sentences elicited larger PPDs, and whether this was accompanied by later PPDs depended on time alignment: The delayed PPD with longer stimuli is largely compensated for when sentences are aligned by their offset. Shaded area represented 1 standard error from the mean.
