When is enough, enough? A comment on Grodzinsky and Marek's "Algorithmic and heuristic processes revisited".

In this comment I argue that although Y. Grodzinsky & A. Marek's (1983, Brain and Language, 33, 216-225) criticism of the conclusions reached by A. Caramazza and E. B. Zurif (1976, Brain and Language, 3, 572-582) in their paper on comprehension disorders in so-called agrammatic patients is not entirely without technical merit, its impact on the claims made by Caramazza and Zurif is inconsequential. I show that there are deeper theoretical and methodological reasons which undermine the claims made by Caramazza and Zurif and the only superficially different proposal of Grodzinsky and Marek.
