Grodzinsky's theory of agrammatic sentence processing fails to account for crucial empirical facts. In contrast to his predictions, the data show that there are (1) degrees of severity and (2) problems with sentences that do not require movement, and that (3) under the right task circumstances, full-fledged syntactic trees are constructed.
