Morphological and phonological processes are tightly interrelated in spoken production. During processing, morphological processes must combine the phonological content of individual morphemes to produce a phonological representation that is suitable for driving phonological processing. Further, morpheme assembly frequently causes changes in a…

It is often assumed that language is supported by domain-specific neural mechanisms, in part based on neuropsychological data from aphasia. If, however, language relies on domain-general mechanisms, it would be expected that deficits in non-linguistic cognitive processing should co-occur with aphasia. In this paper, we report a study of sequential…

A hypothesis for the aphasic syndrome of aggramatism--the omission of function words and inflectional morphemes--is presented. The author tests and illustrates the efficacy of closely observing substantive universals of grammatical structure in proposing accounts of linguistic defects. (Author/MV)

Kean (EJ 165 107) presented a linguistic model to account for the features of the syndrome of Broca's aphasia, especially their agrammatism. This paper critiques Kean's paper by describing and evaluating her five major arguments. It is concluded that Kean's phonological model cannot account for agrammatism as well as syntactic models can.…

Investigated the source of agrammatic aphasic patients' difficulty comprehending semantically reversible sentences. Found approximately equal distributions of three distinct patterns. Results conflict with explanations of comprehension failure which state that a single pattern of performance on sentence structures characterizes comprehension of…
