Dr. Hurley's Study

According to the article Primary progressive aphasia (PPA) is a degenerative syndrome that causes gradual atrophy of the left hemisphere language network, leading to impairments of object naming (anomia) and word comprehension. There were many types of experiments and assessments for different individuals. These type of experiments were done to find out if the condition of aphasia was caused by visual perception problems or verbal problems. This study was using Western aphasia battery and Pea body picture vocabulary test, Northwestern Anagrams Test. The results were also determined to exam the hypothesis that anomia in PPA-S patients is caused by a distortion in word comprehension and lexical labeling at the specific rather than generic level of identification.
