        신은영 숙명여자대학교 사회 교육과학연구소 2001 사회 교육과학연구 Vol.4 No.2

        The purpose of this study is to experimentally verify the meaning of measuring the 16 intellect factors which Song & Park(1997a) suggest through the combination of the operation dimension, the information dimension and the behavioral dimension of mental ability on the basis of Guilford's intelligence theory and compares the developmental traits of the hierarchical structure model of the intelligence with the age groups of the adolesent and the adulthood. It makes a point of finding the developmental stability of the intellectual structure. The sample sizes ate 5556 including the highschool students and the university students in the area of Seoul, In-Cheon, Pusan, Kwang-ju, Kong-ju. It is used the SPSS programs and LISREL8 program for analyzing the data. For the porpose of this study, the concretely used hypotheses in the study and the results are as follows. 1. Hypothesis Ⅰ Does the 16 intellect factors shown as the result in the interaction of the three dimensions of the mental ability have the construct validity in measuring the intellectual traits of human? As the result of reliability test to verify the item consistency of Song's 16 intellect factors, Cronbach α is .275-.906 which suggest the reliable level of the factors. And the factor analytic result shows the validity of the 16 factor structures which the eigen values are more than 1.00 x^2 /df-4.08., These results support the intelligence studies(Hwang, 1984; Song, 1995; Song et al., 1997a; Bachelor, 1989; Clampham, 1996; Guilford, 1962; Meeker, 1990) which make it possible to approach to the multi-dimensional intelligence as combining the operation, the information and the behavior of mental ability. Song et al'.s(1997a) three dimensional interpretations of the mental processes functioning in the measurable factor if the intelligence make it possible to define the intelligence as the systematic collcetion of abilities and the intelligence as function of processing the many kinds of information in a different form(Chiba, 1988). That is, the results of this study show that the 16 intellectual factors can include the ability in the context of individual differences and the function in the context of solving the problems. 2. Hypothesis Ⅱ Do the correlation matrices of the 16 measurement variables keep balance among the three age groups? The result using the equality constraint among 17, 20, 23 age groups with hierarchical model could not fine the significant differences in the three age groups. And this resul supports the developmental stability of the intellectual structure. Through the above results, this study has several significances as follows. First, expeimentally the tested result which the 16 intellect factors based on Guilford's SOI are reasonable, implies that the problem solving ability of human is not by the factor analysis of the single dimension but also by the interaction among the dimension. That is to say, this study is actually the first significance that it is possible to search the factors as the mental processes under the intellect factors. Second, as the 16 intellectual factors reflect the three dimensions of mental ability, it has practical values in the meaning of getting the useful information about the ability constructs of the individual. Third, the result of the developmental stability among groups of 17 to 23 ages implies the practical value that the focus on the study of the intelligence after the adolescent needs to investigate the possibilities of the changes in the individual abilities as following the time, the cultural, and the educational factors.

        지능측정모형의 확인적 연구 - 청소년기를 중심으로

        신은영 한국교육평가학회 2003 교육평가연구 Vol.16 No.2

        본 연구는 Guilford의 지능이론에 근거한 16개의 측정변인을 3단계와 4단계 위계적 지능구조 모형의 적합성을 비교하고 타당한 모형의 발달적 안정성을 확인하였다 연구의 표집은 5556명을 대상으로 하였으며 자료분석을 위해 LISREL프로그램을 사용하였다. 연구결과는 다음과 같다. 위계적 지능구조에 대한 확인적 요인분석 결과는 g를 정점으로하는 지능의 3단계구조모형이 통계적 타당성을 갖는 것으로 나타났다. 또한 청소년기의 지능구조의 발달적 특징을 검증하기 위한 분석결과 연령에 따른 지능구조의 변화에는 의의있는 차이점를 발견하지 못했다. The porpose of this study is to verify the appropriateness of hierarchical strucure of intelligence with 16 intellectual factors which arc suggested by Song et al.(l997d). In this study I hypochesize 2 competing models based on Gf-Gc theory and Guilford's SOl. Then I explore the best fittness model of 2 hierarchical models. After that, I compares the developmental trats of the hierarchical structure model of the intelligence with the age group of the adolesent and the adulthood. The sample sizes are 5556 including the highschool students and the university student in the area of Seoul, In-cheon, Pusan, Kwang-joo and Kong-joo. The LISREL8 program is used to analyze the data. The results are follows: The confirmatory factor analytic investigation shows the 3rd-order factor model are more suitable than the 4th~order factor model which combined by the SOl. This study supports the third-order factor model putting g-factor on the apex and the second-order factors are Gf-Gc-Gcr. In the hierarchical model 1.3.1 verified as valid excludes the possibility that 16 measurement variables can be related with higher-concept overlappingly. But Carroll(1993), Keith et al(I996) suggested the relaxed- model or other higher-concepts between g and second-order factors. So, model 1.3.1 can be more confirmatory test and modification. In methodological aspect, with using the structure equation model connected factor analysis with path analysis it is possible to measure the error variance within the measurement model. And the latent variables which are the higher-order concept from the 16 intellectual factors and the caual relationships between the latent variables let the structure model lead to the factor structure of intelligence with g at the top of the hierarchical model. The result using the equality constraint among 17, 20, 23 age groups with hierarchical model could not find the significant differences in the three age groups. And this result supports the developmental stability of the intellectual structure. This implies the practical value that the focus on the study of the intelligence after the adolescent needs to investigate the possibilities of the changes in the individual abilities as following the time, the cultural, and the educational factors.

        노인군에서 교차소음자극 전·후의 일과성음 유발이음향방사 비교

        신은영,조수진 한국청각언어재활학회 2014 Audiology and Speech Research Vol.10 No.3

        The purpose of this study was to investigate Transient Evoked Otoacoustic Emissions (TEOAEs) with alternate stimulation for elderly group and suggest probability between tinnitus and efferent system. Twenty-eight subjects (56ears) ranging from 65 to 86 years old were participated. The pure tone threshold average (0.5, 1, 2 kHz) of theright ear was 32.22±14.65 dB HL and the left was 28.83±11.64 dB HL. There were nineteen subjects without tinnitus and the others had various tinnitus. Four out of tinnitus group had spontaneous right unilateral type, two out of them had bilateral type, while the others had intermittent tinnitus in somewhere of head. Alternate stimulation for contralateral suppression of TEOAEs was broad band noise of 70 dB SPL. Contralateral suppressions of TEOAEswere recorded in almost all subjects used every frequency (1, 1.4, 2, 2.8, 4 kHz), and TEOAEs suppressions wereshown significantly on left ears of all subjects (t = -2.06, p = .049). TEOAEs of female were lower than male's inalmost frequencies except 4 kHz, but TEOAEs differences of suppression were not appeared significantly between male and female (p > .05). Alternate TEOAEs suppressions were investigated in all frequencies without tinnitus group and varied in each frequency with tinnitus group. These results were achieved using a small pool of subjects but exposed a possibility for clinical application of TEOAEs associated with the efferent system.
