The purpose of this study was to analyze retrospectively the perseverative responses which appeared in Japanese standardized aphasic tests : the Standard Language Test of Aphasia (SLTA) and the Differential Diagnostic Test of Aphasia (DDTA) . Sixty-four aphasic patients served as subjects : 30 for SLTA and 34 for DDTA. Results indicated that perseveration was observed significantly more frequantly in the naming task than in the repetition or oral reading tasks ; also, degree of perseveration correlated significantly to the severity of aphasia. In the naming tasks in both tests, patients with less than 4 months after onset of aphasia showed more perseveration than those with more than 4 months. Perseverative responses decreased during their recovery courses. Three types of perseveration—total, partial and other types—were observed in both tests, with significantly higher incidence of the total type than the partial type in SLTA, but with similar incidence in DDTA.
