Tracking passive sentence comprehension in agrammatic aphasia

►We used eye tracking to study passive sentence comprehension in agrammatic aphasia. ►Aphasic and control participants performed a sentence-picture matching task. ►Controls exhibited agent-first processing; aphasic participants did not. ►Controls reached correct interpretations at the verb; aphasic participants did not. ►Impaired passive comprehension in aphasia may stem from lexical processing deficits.
