The purpose of the study was to investigate whether there are differences in confrontation naming ability, generative naming ability, hearing handicap, and depression in community-dwelling elderly by age group, and whether there is any correlation among them, and to find out what factors explain the two naming abilities (confront and generative) of the elderly. Sixty-five community-dwelling elderly people participated: 65~74 years were classified into young-old; 75~84 years into old-old; and 85 years and over into oldest-old. K-BNT-15 for the confrontation naming ability, animal naming test for the generative naming ability, K-HHIE for the subjective hearing handicap, and GDS for the subjective depression were administered. First, there was a statistically significant difference in confrontation naming and depression levels according to age groups. Second, there was a positive correlation between chronological age and subjective depression level and between subjective hearing handicap level and subjective depression level, and a negative correlation between education level and subjective depression level. Third, the confrontation naming score was explained by age, and the generative naming score was explained by subjective depression level. The results show that naming abilities, subjective hearing handicap, and subjective depression level are not simply the result of normal aging and that a convergence approach is needed in various fields to solve the issue.

The present study identify the predictive power of confrontational naming and generative naming as screening tests for normal and early cognitive impairment. The subjects were analyzed for 203 healthy elderly, 106 mild cognitive impairment (MCI), 31 mild dementia. The confrontational naming was measured by the short-term Korean Boston Name Waiting Test, and the generative naming was measured by the Control Associative Word Test. As a result of polynomial logistic regression, both confrontational naming and generative naming had a significant effect on discriminating cognitive impairment (MCI, mild dementia) in general elderly (p<0.05). On the other hand, when distinguishing mild dementia from mild cognitive impairment, the generative naming-phonetic test had no significant odds ratio. The results of this study suggest that when discriminating mild dementia in mild cognitive impairment group, it is not meaningful to look only at the total score of generative naming test.

Impaired naming difficulty is common in normal elderly as well as in patients with neurological impairment. The 60-item Korean version-Boston Naming Test(K-BNT) is one of the most commonly used test for measuring confrontational naming ability. However, age-related cognitive decline may make the elderly difficult concentrating during the 60-item test, therefore, item reduction of the K-BNT would improve test validity and reliability. Thus, the purpose of this study was to develop a short form of the K-BNT based on Item Response Theory(IRT). Considering item-fit index, sex factor, and item difficulty through Rasch analysis, the 15-item K-BNT(i.e., K-BNT-15) was developed. Via administration of the K-BNT-15, we observed age-related decline in naming ability and significantly different performance between the normal elderly and patients with mild cognitive impairment. This study demonstrates the utility of IRT for developing a short-form language evaluation tool. The K-BNT-15 can be effective as a language screening tool to differentiate between normal aging and pathological diseases.

The purpose of this study is to investigate effects of three conditions-words frequency, word length, and animacy-on the performance of naming in nonfluent aphasic patients. 15 nonfluent aphasic patients and 15 normal adults were participated in this study. The words consist only of concrete nouns and confrontational naming test was used. The test consisted of 40 questions and the condition of word were frequency(low-frequency/high-frequency), length(1 syllable/3 syllables) and animacy(animate/inanimate). The result of the study was as follows. First, naming was performed better with high-frequency words than with low-frequency words in both groups. Second, naming was performed better with 1 syllable words than with 3 syllable words in both groups. Third, naming performance depending on animacy did not show significant differences in both groups. These results indicate that compared to animacy of word, word frequency and length have bigger influence on the naming, and the difference by word frequency was more pronounced for nonfluent aphasic patients than for normal adults. The results of this study suggest that target word for the assessment and intervention of nonfluent aphasic patients, words frequency should be considered first in clinical setting.

Mini-Mental State Examination (MMSE) and naming tests have been used clinically as screening and diagnostic tools for mild cognitive impairment and dementia. Researches in other countries have reported that residential areas would affect one's cognitive abilities. In Korean, however, there was no systematic studies on geographical influences to cognitive ability among a sample of urban/rural residents. The aim of this study was to investigate the effect of urban/rural locality of residence on cognitive tests in normal elderly Korean. Residents aged 65 years and older (N=108) were administered the K-MMSE, confrontation/generative naming tests, and medical/socio-demographic interview. When comparing the total number of correct responses between urban residents and rural residents, the performances of rural group were significantly worse than those of the urban group in K-MMSE. Based on the results, our finding suggests that a factor of residential locality should be considered to examine the function and explain the cognitive decline in rural community-dwelling elders.

The purpose of this study was to investigate the characteristics of error types in naming task for 8 questionable demeatia groups, 9 definite dementia groups, and 10 normal groups. The items of naming error analysis were classified into visual perception errors, semantic association errors, semantic non-correlation errors, phoneme errors, Don't Know, and No Response. For the analysis, descriptive statistics analysis, analysis of variance, and multivariate analysis of variance were conducted using SPSS 21.0. As a result, there was a significant difference in the error rate between groups according to the error type. The errors that showed significant differences between the normal group and the other two groups were visual perception errors and semantic non-related errors. The error of non-response was different from the dementia confirmation group, but there was no significant difference from the dementia suspicion group. These results showed that Alzheimer's patients had a defect in confrontation naming ability. Also, it was found that it is appropriate to provid other clues when the defects caused by the degeneration of a specific step during the information processing process become severe.

Objective : The purpose of this study was to investigate the effect of hand tapping on the accuracy and the fluency of speech production in children with speech sound disorder(SSD) and their typically developing peers(TD). Methods : The study subjects were 15 SSD children and 15 TD children aged 4, 5, and 6 years of age. Subjects were asked to give a picture name without hand tapping in the first experimental condition, and with hand tapping in the second experiment condition. Results : The results showed that hand tapping significantly increased disfluency in TD, whereas in SSD. it did not affect the accuracy or fluency of speech production. In addition, TD demonstrated a significant positive correlation with the changes of accuracy and disfluency due to hand tapping, whereas SSD had no correlation. Conclusion : We discussed the possibility that hand tapping could serve as an obstacle distracting attention from SSD and TD, acting as a motor gesture to facilitate phonological processing when facing the difficulty in lexical retrieval for SSD.
