황유미(Yu Mi Hwang),이호영(Ho Young Yi),남기춘(Kichun Nam) 한국언어청각임상학회 2009 Communication Sciences and Disorders Vol.14 No.2

배경 및 목적: 한국어의 보조용언은 본용언(일반 용언)과 동일한 형태를 갖고 있으나 통사적구성과 의미적 특성의 차이로 인해 여러 이론적 논의의 주제가 되어 왔다. 본 연구는 한국어보조용언의 심성어휘 표상 양식 및 정보처리의 양상을 밝히는 데 목적을 두고 있다. 방법:본용언과 보조용언으로 모두 사용되는 9개의 용언을 선정하여 동일한 형태의 용언(예: 가다)을 대상으로 본용언 문맥(예: 철수가 집에 갔다)과 보조용언 문맥(예: 밥이 다 되어 갔다)에서본용언의 의미가 활성화되는지 의미점화 어휘판단과제(semantically primed lexical decisiontask)를 실시하였다. SOA (Stimulus Onset Asynchrony)를 150ms (실험 1)와 1,000ms (실험 2)로 조정하여 실험하였다. 결과: 실험 결과 SOA 150ms (실험 1)와 SOA 1,000ms (실험2)에서 본용언 문맥과 보조용언 문맥에서 모두 본용언 관련 목표어에 대한 의미적 활성화가유의미하게 관찰되었다. 논의 및 결론: 본 실험 결과를 통해 한국어의 보조용언은 국어학적으로 본용언과 의미적, 구문론적 차이가 구분되지만 언어정보처리의 측면에서는 유사한 정보처리의 양상이 관찰되므로 심성어휘집에서 보조용언의 표상 설정에 있어 본용언과의 관련성이고려되어야 할 것으로 보인다 Background & Objectives: The purpose of this study was to investigate the processing and mental representation of main verbs and auxiliary verbs. Korean auxiliary verbs take the same structure as main verbs but their syntactic and semantic functions do not correspond to those of main verbs. Methods: Nine verbs that can be used as both main and supportive verbs were selected to examine the semantic priming effect during semantically primed lexical decision tasks. For example, the verb form “ga-da(가다)” can be used in the main verb context (철수가 집에 갔다: “Cheol-Su went home”) as well as in an auxiliary verb context (밥이 다 되어 갔다: “The rice was getting almost ready”). These two verb contexts were compared to examine semantic priming effects. In Experiment 1, SOA (Stimulus Onset Asynchrony) was controlled for 150ms and in Experiment 2, SOA was controlled for 1,000ms. Results: The results of this study demonstrate that there is a significant semantic priming effect for the target verb form in both main verb and auxiliary verb contexts when SOA was 150ms (Experiment 1) and 1,000ms (Experiment 2). Discussion & Conclusion: In conclusion, although Korean auxiliary verbs can be semantically and syntactically distinguished from main verbs, similar processing aspects were observed. Therefore, the relevance of auxiliary verbs to main verbs should be considered when establishing a mental lexicon for auxiliary verbs

This study was carried out to investigate preference and purchase factors of seaweed in some regional residents of Korea. Subjects were residents (n=1,218) whose residential area was divided into inland and coastal region and the survey was done during December 2007. Especially, purchase factors of seaweeds was conducted only in married females (n=353). The subjects are composed of 46.5% male and 53.5% female. Regional distribution of subjects was found to be 16~17%, with highest ratio in the age bracket of 20~29 years old. Proportion of students, at 29.8%, was the highest ranking occupation of the subjects. Preference score of seaweeds by region was highest for laver followed by brown seaweed and sea tangle. In terms of preference by gender, female subjects displayed higher preference score for green laver (p<0.01), seaweed fusiforme, brown seaweed, sea tangle (p<0.001) than the male subjects. Considerations being made when purchasing seaweeds for each region were in the order of freshness, taste and nutrition. In comparing the inland and coastal region, scores of freshness, convenience, design and color for the coastal region was higher, displaying significant difference.

This study discusses semantic knowledge and subcategorization of animals for Koreans based on a semantic verbal fluency task. Compared to many previous studies which focused on the number of animals in response or the switches between clusters, we aim to identify diversity and universality of semantic knowledge about animals and to propose subcategories of animals. Instead of using pre-existing semantic categories proposed by previous studies, we argue for Korean specific semantic knowledge and categories of animals based on healthy Korean adults’ semantic knowledge. We evaluated 275 cognitively healthy volunteers, aged 45 to 86 years. An educational average level ± standard deviation for the whole sample is 9.89 ± 4.2 years. As a result of the fluency task, the participants mentioned 193 different types of animals with the number of 4,047. They named an animal with the following order of preferences: ‘a tiger, a dog, a cow, a pig, a chicken, a lion, an elephant, a horse, a duck, a rabbit, a giraffe, etc.’ The top ranked animals among 193 types in naming can be regarded as a “typical” animal among Korean people. With respect to category-based induction, typicality can be a case of a more universal tendency. In order to examine subcategories of animals, we extracted a bigram from the response list. We derived dice distances to measure similarity between two co-occurring items and provided a perceptual map based on multidimensional scaling with statistical methods using R.

This paper investigates the typicality of category members based on the order mentioned in the naming task. The naming task, also known as controlled oral word association task, is a test in which a speaker names as many words as he or she can. The mentioned words in a certain category are produced in a limited time. The task is used to discover semantic knowledge and semantic fluency. The type and number of category members can vary depending on the individual. This study observes typicality in the category members based on the following factors: the first mentioned word, the characteristics in the sequence of mentioned words, the order of words mentioned in a lesser category, and the most mentioned word. Typicality is different from familiarity in the naming task. The result identifies Koreans think of a dog and a cow as typical members in the animal category; the typical subcategory of an animal is a farm animal. The study suggests a simple and appealing idea about the way people decide the most typical members in a category based on the order of utterance.

배경 및 목적: 본 연구에서는 좌반구 손상 실어증 환자와 정상 성인들을 대상으로 의미연결 과제와 이름대기 과제에서 고유명사와 보통명사에 따라 수행력에 차이가 있는지를 알아보았다. 방법: 좌반구 손상 실어증 환자와 정상 성인 각 20명을 대상으로, 고유명사 의미연결, 보통명사 의미연결, 고유명사 이름대기, 보통명사 이름대기 과제를 실시하여 정반응 점수를 비교하였고, 실어증 집단에서 각 과제의 수행력 간 상관관계가 어떠한지 분석하였다. 결과: 집단 간 차이 및 과제유형에 따른 차이는 통계적으로 유의하였으나, 명사종류에 따른 차이는 유의하지 않았다. 또한 명사종류와 집단 간 상호작용효과는 통계적으로 유의하지 않았으나, 과제유형과 집단 간, 명사종류와 과제유형 간, 그리고 명사종류, 과제유형과 집단 간 상호작용 효과가 모두 유의하였다. 실어증 집단에서 모든 과제 수행력 간 유의한 상관이 있었고, 그 중 고유명사 의미연결 과제와 보통명사 의미연결 과제의 상관계수가 매우 높은 것으로 나타났다. 논의 및 결론: 실어증 집단에서 의미연결 과제 수행 시 고유명사의 점수가 보통명사보다 유의하게 좋다는 것을 확인하였다. 본 연구는 고유명사의 경우 우반구의 기능, 즉 시각정보의 활성화가 의미처리에 관여할 가능성, 그로 인해 좌반구가 손상된 실어증 환자가 손상되지 않은 우반구를 활용하여 고유명사 의미처리에 도움을 받았을 가능성을 제시하고 있다. Objectives: The aim of this study was to determine whether performance differs between proper nouns and common nouns in semantic and naming tasks between patients with aphasia and normal adults. Methods: 20 patients with aphasia and 20 normal adults performed a proper noun semantic task, common noun semantic task, proper noun naming task, and common noun naming task. Following this, we compared the scores and analyzed the correlation among the four tasks. Results: The differences among the groups and the types of tasks were statistically significant, but not according to the noun types. Also, noun type and group interaction effect were not statistically significant; but task type and group, noun type and task type, and noun type, task type and group interaction effect were significant. In the aphasia group, there was a significant correlation between the performance of all tasks, and the correlation coefficient between the proper noun semantic task and the common noun semantic task was very high. Conclusion: In the aphasia group, we confirmed that the proper noun score was significantly better than the common noun when performing semantic tasks. This study suggests that in the case of proper nouns, the function of the right hemisphere; that is, the activation of visual information, may be involved in semantic processing. As a result, it suggests that aphasia patients with damaged left hemispheres were assisted in the process of proper noun semantics by using the uninjured right hemisphere.

한국판 프렌차이 실어증 선별검사 (Korean version of Frenchay Aphasia Screening Test: K-FAST)의 신뢰도와 타당도

하지완(Ji-Wan Ha),편성범(Sung-Bom Pyun),이호영(Ho Young Lee),황유미(Yu-mi Hwang),남기춘(Kichun Nam) 한국언어청각임상학회 2009 Communication Sciences and Disorders Vol.14 No.1

배경 및 목적: 본 연구에서는 뇌손상 환자에서 한국판 프렌차이 실어증 선별검사(Korean version of Frenchay Aphasia Screening Test: K-FAST, 이하 K-FAST)의 신뢰도와 타당도를 검정하였다. 방법: 신뢰도와 타당도 분석을 위하여 50명의 실어증 환자와 42명의 비실어증뇌손상 환자의 자료를 이용하였다. Chronbach’s ɑ를 통해 문항내적일관성 신뢰도를 측정하였고, Kendall’s coefficient of concordance를 산출하여 검사자간 신뢰도 및 재검사 신뢰도를검정하였다. 총 검사와 하위 검사 간 상관관계를 분석하여 구인타당도를 측정하였고, P․K-WAB과의 상관관계를 통하여 공인타당도를 검정하였다. ROC 곡선을 분석하고 정상인 평균의 -1 표준편차 값을 적용한 절단점을 이용하여 민감도와 특이도를 구하였다. 결과: 문항내적일관성 신뢰도(총 검사 .88, 간략형 검사 .81), 검사자간 신뢰도(총 검사 .92, 간략형 검사.94), 재검사 신뢰도(총 검사 .979~ .990, 간략형 검사 .979~ .998)에서 높거나 매우 높은 신뢰도가 입증되었다. 구인타당도(총 검사와 하위 검사 간 .820~ .973, 간략형 검사와 하위 검사간 .737~ .910)와 공인타당도(총 검사와 실어증지수 간 .904, 간략형 검사와 실어증지수 간.910) 검정 결과 우수한 타당도가 입증되었다. ROC 곡선 분석 결과에서는 진단유용성을 입증하지 못 하였지만, 절단점을 적용한 민감도와 특이도 산출 결과 특이도는 낮지만 민감도는높은 검사로 평가되었다(총 검사의 민감도 90.0%, 특이도 31.0%, 간략형 검사의 민감도 88.0%,특이도 28.6%). 논의 및 결론: K-FAST는 신뢰도, 타당도, 민감도가 높은 검사도구라고 할수 있다. 그러나 뇌손상 환자들의 특성은 검사의 특이도에 부정적인 영향을 줄 수 있으므로,실어증 뿐 아니라 기타 인지 의사소통장애 여부를 선별해주는 도구로 K-FAST를 활용할 것을 제안한다. Background & Objectives: Early identification, diagnosis, and treatment of aphasia are important steps in maximizing rehabilitation gains. A routine screening test is an invaluable tool in the identification and appropriate referral of patients with potential communication problems. Nevertheless, there is nostandardized aphasia screening test available in Korea. The purpose of this study was to test the reliability and validity of the Korean version of the Frenchay Aphasia Screening Test (K-FAST). Methods: We used test data from 50 aphasic patients and 42 non-aphasic, brain-damaged patients. An internal consistency and intra-/inter-rater reliabilities of the K-FAST were analyzed by the Cronbach’s ? value and Kendall's coefficient of concordance, respectively. A constructive validity through correlations between the total and subtest scores and a concurrent validity through correlations between the scores of the K-FAST and K-WAB were measured. The diagnostic accuracy of the K-FAST in brain-damaged patients was measured by the area under the ROC curve, while the sensitivity and specificity were evaluated using the cut-off value of the normal data. Results: Results obtained in the present study were as follows: indices of the internal consistency and intra-/inter-rater reliabilities of the K-FAST showed good reliabilities. There were significantly strong correlations between the total and subtest scores of the K-FAST, and between the scores of K-WAB and K-FAST. For detecting aphasia among brain-damaged patients, the sensitivity was high while the specificity was low. Discussion & Conclusion: Our results show that K-FAST could be a reliable and valid tool for screening Korean Aphasics. However, the specificity of the K-FAST appeared to be adversely affected by the characteristics of the brain-damaged patients.
