Abstract
Linguistic tests, based on an expressive language sample and clinical tests of aphasia, were administered to a minimally impaired aphasic subject in an attempt to compare their relative utility and sensitivity. Tests based on a linguistic framework were found to be far more sensitive to the errors in the subject's language than traditional clinical tests. Specifically, the linguistic tests isolated difficulties with the processing of deep structure relations of complex sentences. Various reasons for the results are suggested and some points are made regarding the validation of theoretical constructs through aphasic language data. A suggested model for the classification, testing and therapy of aphasic disorders, based on linguistic theory, is postulated.

Linguistic tests, based on an expressive language sample and clinical tests of aphasia, were administered to a minimally impaired aphasic subject in an attempt to compare their relative utility and sensitivity
The aim of this study is to determine the value of tests based on current linguistic theory in discovering minimal areas of language difficulty in an aphasic subject
On the basis of the data obtained in this study, it may be concluded that a linguistic approach to the testing of aphasia seems to be very useful for the characterization of a patient's language abilities
