腦半球의 選好와 學業成就 및 知能과의 相觀硏究 = A Study on the Interrelationship among Hemispheric Preference and Academic Achievements and IQ

다국어 초록 (Multilingual Abstract)

1. Problems
The purpose of this study is to display which hemispheric preference is related to academic achievements and IQ. The major research problems are as follows:
1) The relationship between dominant hemispheric preference and academic achievements.
(1) The students who have dominant left hemispheric functions will have a close interrelationship with school subjects which belong to same hemispheric functions. The school subjects are Korean Language, Mathematics, Chemistry, Biology, English, German and French.
(2) The students who have dominant right hemispheric functions will have a close interrelationship with school subjects which belong to same hemispheric functions. The school subjects are Physical Educations, Music, Drawing, Technique and Industry.
2) The relationship between dominant hemispheric preference and intellectual factors.
(1) The students who have dominant left hemispheric functions will have a close interrelationship with verbal and numerical ability.
(2) The students who have dominant right hemispheric functions will have a close interrelationship with visuo-spatial ability.
(3) The students who have integrated functions will have a close interrelationship with IQ.
2. Methods
1) Subjects: The subjects consisted of 327 first grade students of high school in Seoul. (boys: 159, girls: 168).
They were sampled from academic track schools.
2) Instrument: "The Your Style of Learning and Thinking," Form-B was the assesment instrument employed to determine hemispheric preferences.
3) Procedure: The data were collected and scored using the scoring key contained in the Norms - Technical Mannual for Your Style of Learning and Thinking, Form-B (Torrance, et al., 1978).
Each subject's responses were classified as being either right hemisphere oriented, left hemisphere oriented of hemispherically integrated.
Then the sum total of all right hemispheric responses was calculated for each subject.
Sums were also calculated for both the total left hemispheric and integrated responses of each subject.
Each dominant hemisphere was compared with each school subject. Related school subjects were Korean Language, Mathematics, Chemistry, Biology, Physical Education, Music, Drawing, English, French, German, Technique and Industry.
Related intellectual factors were verbal ability, spatial ability, numerical ability and IQ.
3. Results
The results of this study are as follows:
First, Mathematics, Chemistry, Biology and Numerical ability were confirmed as having significantly greater interrelationship with left hemispheric responses as expected in research problem.
Second, Korean Language, English, French, German and Verbal ability didn't display any interrelationship with left hemispheric responses.
Third, Technique and Industry displayed slightly significant interrelationship but Music and Physical Education didn't display any interrelationship with right hemispheric responses.
Fourth, Spatial ability displayed higher significant interrelationship and Drawing also displayed slightly significant interrelationship with integrated responses.
Fifth, IQ was confirmed as having closely significant interrelationship with integrated responses as expected in research problem.
On the basis of the results, this study, as a whole, displayed Significant interrelationship as expected in research problems and the measuring instrument of hemispheric preference was proved to have some validity in this study.
This study can be summarized as follows:
First, Left hemispheric functions were more related to science and numerical ability than language subjects.
Second, Technique and Industry displayed a bit of significant interrelationship with right hemispheric functions but they displayed negative interrelationship.
Third, IQ and Spatial ability displayed greatly significant interrelationship and Drawing also displayed some significant interrelationship with integrated functions.
Finally, As showed in this study, Science and Mathematics displayed strong tendancy toward left hemispheric functions.
Those who insist the importance of hemispheric functions have critical viewpoint on the emphasis of left hemispheric functions. They insist that right and integrated hemispheric functions be developed. It will be necessary to make a good measuring instrument through more detailed item analysis and also necessary further studies testifying both hemispheric symmetry or dominant integrated functions. It the contents of learning can be programmed and students can be educated.
