In particular, she presents two current hypotheses of syntactic deficits in agrammatism
based on Chomsky's (1992) theory of syntax: 1) the Trace-Deletion Hypothesis (Grodzinsky 1995) which focuses on syntactic processing in comprehension and 2) the Tree-Pruning Hypothesis (Friedmann and Grodzinsky 1997) which attempts to account for agrammatic production.
Participants at each site were recruited as part of a large-scale study examining treatment-induced changes in brain function and, hence, were selected for specific language-deficit patterns: agrammatism
(NU), anomia (BU, MGH), and dysgraphia (JHU).
He further proposes that the evolution of lexical speech automatisms (such as language cliches, overused social expressions, automatic speech, and the like) to agrammatism
(a type of language pattern frequently found in severe nonfluent aphasia) might also provide useful insights into the early evolution of language.
as interactional artifact and achievement.
This profile resembles to a combination of NFAV-PPA (i.e., non-fluency, agrammatism
, effortful speech) and LV-PPA (i.e., anomia and impaired repetition, but intact single-word comprehension).
is a condition that prevents people from forming complete or coherent sentences.
On the whole, within the group, there was a decrease in the frequency of literal paraphasias and sensory agrammatism
. In a majority of cases, there was recovery of automatic speech, including listing of months of the year (p < .05).
It complements existing comparative studies on agrammatism
Whereas sentence production impairment is the hallmark of agrammatism
, there is considerable individual variability in the extent of other deficits [8, 9].
