Agrammatism in Jordanian-Arabic speakers

The studies of agrammatism show that not all morpho-syntactic elements are impaired to the same degree and that some of this variation may be due to language-specific differences. This study investigated the production of morpho-syntactic elements in 15 Jordanian-Arabic (JA) speaking individuals with agrammatism and 15 age-matched neurologically healthy individuals. Two experiments were conducted to examine the production of complementizer, tense, agreement and negation morphology in JA. The results indicated that the speakers of JA with agrammatism had marked dissociations in producing specific morpho-syntactic elements. The observed impairment patterns overlapped, in many respects, with those observed in other linguistic groups. The findings are discussed with respect to current theories of agrammatism, including both morpho-syntactic and computational accounts
