title: Tense and syntactic processes in agrammatic speech.
abstract: This study focuses on inflectional errors in a group of eight, English-speaking people with agrammatism. Subjects were required to provide inflected verbs in declarative sentences and construct negative sentences. The errors made by these speakers are considered in terms of whether they resemble the errors made by children at the Optional Infinitive Stage. Results confirm that the errors differ from those made by children and that a different explanation is required. Explanations offered by Borer and Rohrbacher (1997) and by Friedmann and Grodzinsky (2000) are discussed but are considered inadequate to deal with our data. It is proposed that agrammatic speakers have problems with the implementation of grammar and particularly with syntactic processes such as feature-checking.
