Multi-dimensional verbal short-term memory mechanisms are largely divided into the phonological channel and the lexical-semantic channel. The former is called phonological short-term memory and the latter is called semantic short-term memory. Phonological short-term memory is further segmented into the phonological input buffer and the phonological output buffer. In this study, the language performance of each of three patients with similar levels of conduction aphasia was analyzed in terms of multi-dimensional verbal short-term memory. To this end, three patients with conduction aphasia were instructed to perform four different aspects of language tasks that are spontaneous speaking, repetition, spontaneous writing, and dictation in both word and sentence level. Moreover, the patients' phonological memories and semantic short-term memories were evaluated using digit span tests and verbal learning tests. As a result, the three subjects exhibited various types of performances and error responses in the four aspects of language tests, and the short-term memory tests also did not produce identical results. The language performance of three patients with conduction aphasia can be explained according to whether the defects occurred in the semantic short-term memory, phonological input buffer and/or phonological output buffer. In this study, the relations between language and multi-dimensional verbal short-term memory were discussed based on the results of language tests and short-term memory tests in patients with conduction aphasia.

The purpose of this study was to determine the effects of group therapy on the language performance of aphasic patients. Four aphasic subjects participated in group therapy. Their aphasic types were TCMA (transcortical motor aphasia), conduction, anomie, and Broca's aphasia. The focus of the therapy was to stimulate cooperative learning skills. For this purpose, categorization tasks, semantic association tasks, convergent thinking, and divergent thinking tasks were employed. The results showed that all of the aphasic subjects demonstrated some improvement in writing ability, categorization ability, and speaking ability in sentences.

Language is one aspect of cognition, along with attention and concentration, learning and memory, visuospatial abilities, and executive function. The purpose of this study was to determine the effect of language intervention by cognitive approach on language expressive performance in a patient with conduction aphasia. This study used several tasks such as Attention and concentration task, visual memory tasks, memory tasks, categorization, divergent thinking, self-monitoring and evaluate thinking. The effects of treatment were evaluated by periodic probing of both trained and untrained familiar words in three tasks; picture naming, answering to questions and telling stories. The results showed improvements both in trained and untrained words. Therefore, we concluded that expressive language performance of this aphasic patient is amenable to this intervention, and that cognitive therapy approach can be useful.

Aphasia is speech disorder caused by injuries on the speech nerve center. It usually occur due to a disease in the right cerebral cortex and is divided into the various aphasia such as Global aphasia, Broca's aphasia, Wernicke's aphasia, conduction aphasia, Anomic aphasia, etc. Jihwangumja is used the cerebral infarction with Aphasia due to deficiency syndrome of kidneys. The purpose of this study is to examine the efficacy of oriental treatment for cerebral infarction with aphasia by Jihwangumsa. In the hospital, the patient showed the symptoms of mental disorder, Rt. hemiparesis G3/G4, aphasia, chest discomfort, obstipation, frequent urination, etc. The case showed that acute infarction on Lt. fronto-temporo-parietal lobe in Brain-CT. We identified the patient's clinical conditions and treated accordingly. As a result of treatment, symptoms were markedly improved and he was discharged. Further elaboration of oriental diagnostic classification could possibly lead to the fundamental treatment.

The argument-structure distributions of predicates in the speech of two roca-type aphasic patients and one Conduction-type patient are compared with both matched controls and each other on the basis of narrative production data. Whereas English-speaking agrammatics have been reported to have difficulties producing noncopular unaccusative predicates (Kegl 1995) Korean-speaking agrammatics are found not to have particular difficulties with unaccusative predicates. On the assumption that agrammatics lack specific syntactic knowledge for the processing of displaced arguments from their lexically specified positions. it is proposed that unaccusatives in Korean do not involve the displacement of arguments for Case-theoretic reasons or involve a vacuous movement. if any.

The characteristics of generative naming ability between fluent aphasiacs and non-fluent aphasics were investigated for 10 fluent aphasics (6 Wernicke's and 4 conduction type) and 10 non-fluent aphasics (6 Broca's and 4 transcortical motor type). Subjects were given 2 types of generative naming task and asked to generate lists of words to categorical ('animal', 'things at a supermarket') and phonetic ('ㄱ', 'ㅇ', 'ㅅ') cues. The total numbers of correct and incorrect response and error type ratios were calculated. The results of the present study were as follows: (1) Fluent aphasics had higher generative naming scores than non-fluent aphasics. (2) A remarkable dissociation between performance on categorical and phonetic cue in both aphasic groups was observed. Both aphasic groups produced a large number of responses in the categorical cue. (3) There was no significant group-difference in the error type. (4) Any correlation between generative naming and confrontation naming in K - WAB was not found.
