Comparison of Syntactic Comprehension With Grammatical Judgment in Patients With Aphasia

Damage resulted from two linguistic features of syntactic comprehension and grammatical judgment in patients suffering from Aphasia, weakening the linguistic function, affecting cognitive skills. Therefore, the present study has been conducted to compare the extent of syntactic comprehension and grammatical judgment in patients with Aphasia.

This study is descriptive-comparative. Forty-five patients with Aphasia were selected by a simple random sampling method. The data were collected by a researcher-developed demographic questionnaire, Persian Aphasia Battery (PAB) test, and syntactic comprehension and grammatical judgment test and were analyzed by the Chi-square test.

In general, the patients suffering from Aphasia are more affected by syntactic comprehension damage than grammatical judgment. This difference was significant in the comprehension of dative sentences than replacing complex short sentences, predicative accusative than tracing the long simple sentences, understanding of inverted sentences than tracing long, complex sentences, nominative connectives than long simple sentences, nominative predicative than long simple sentences, and inverted dative sentences than replacing long, complex sentences (P<0.05). Despite the significant difference between the damage of syntactic comprehension in patients with Aphasia and their grammatical judgment, no significant difference was seen in the comprehension of active and continuous sentences

According to the results, there was a significant difference between the extent of damage of syntactic comprehension compared to the damage of grammatical judgment in the patients suffering from Aphasia. Therefore, the grammatical judgment of the patients was better than their syntactic comprehension.
