Lesions’ Mapping of Different Types of Aphasia through the Application of (WAB-R): A Linguistic Analysis
Hassan, Samar;
Abstract
The objective of this study is to investigate the linguistic deficits of Egyptian Arabic in patients with aphasia by using the translation of the Western Aphasia Battery Revised language test (WAB-R) into Egyptian Cairene Arabic which was used to evaluate their performance (Jomaa, 2017, 2023). The generalizations vary depending on the severity and location of the damage which can affect different aspects of language performance. This thesis investigates the linguistic behavior of eight aphasic patients according to Broca’s aphasia (frontal lobe) and Wernicke’s aphasia (parietal lobe). The syntax/semantic asymmetry is insightful with respect to the linguistic analysis in the patient’s data of the two areas in the brain: Broca’s and Wernicke’s. In Broca’s area, the patients’ data demonstrate the fact that a distinction has to be made between semantics and syntax. Their semantic is intact, whereas their linguistic performance is severely disrupted. This case study reveals that half the patients, who have a lesion in Broca’s area, suffer from severe linguistic performance/production. However, their competence is intact. They phonologically struggle with pronouncing certain voiceless fricatives, and multi-syllabic structures. Syntactically, they could not form complete grammatical sentences due to the lesion of the insula region in the brain’s frontal lobe. In contrast, the other four patients, who have a lesion in Wernicke’s area, are with intact performance but language comprehension problems. They produce flawless complex sentences but they have difficulty with understanding and comprehension. This corroborates Chomsky’s innateness hypothesis, that the brain has a set of finite universal rules that generate the sentences of a given language. In Wernicke’s area, the patients demonstrate a flawless performance of syntax, morphology and phonology but their comprehension/semantics is totally absent. It simply does not exist. The study aims to provide insights into the nature of language processing deficits and the factors that influence linguistic competence and performance.

| BUHUTH_Volume1_Issue6_Pages41-73.pdf | The main purpose of this research paper is to investigate the effect of the injured brain regions of the patients, who suffer from aphasia. This study is from a linguistic perspective. This will be investigated from various perspectives, specifically phonology and syntax. As these study cases face major problems especially in these two linguistic aspects. Some of these language deficits prove that the human brain contains a constrained and well-characterized faculty. The function of this faculty is to represent the sentence structure (Dick et al., 2001, p.759). Moreover, this paper represents the various types of aphasia, by focusing on showing the injured areas in the brain after cerebrovascular stroke. This paper presents three cases who suffer from Anomic Aphasia. The diagnosis of the patients in this research is conducted within the framework of The Western Aphasia Battery Revised (WAB-R), which is a scale of questions that is used to determine the language deficiencies that the patients suffer from (Gom‟a et al., forthcoming). After the application of this test, specific regions in the brain, that are responsible for language production and comprehension, are going to be shown. Moreover, it represents the localization theory and how it is related to the human brain. Finally, it investigates the relation between localization theory and Chomsky's distinction between Competence and Performance. | 1.12 MB | Adobe PDF | Request a copy |
