- 本 硏究는 한글에서 視混同을 많이 일으키는 基本자모와 派生자모의 쌍들을 뽑아, 基本자모가 派生자모로 판단되는 境界가 어디인지를 밝히고, 細部特徵들간의 比(예, "ㅋ"의 경우 위 수평선이 L이고 중간 수평선이 ℓ로서 ℓ/L比 )가 어떠할 때 좋은 형태의 자모인지를 밝히려고 시도되었다. 또한 生成法과 分類法의 實驗課題를 사용하여 두 실험과제에 걸쳐 一般化된 效果가 나타나는지를 검증하였다.
實驗 Ⅰ에서는 피험자들에게 좋은 형태의 자모와 애매한 형태의 자모를 주어진 基本선 위에 生成토록 하는 生成課題를 사용하였다. 實驗 Ⅰ의 결과는 좋은 형태의 자음은 좋은 형태의 모음보다 一般的으로 ℓ/L比가 켰다. 좋은 형태의 자음과 모음은 자모간에 각기 차이가 있었다. 애매한 형태에 있어서도 자음이 모음보다 ℓ/L比가 컸다. 애매한 형태에서 자음은 쌍간에 차이가 있었으나 모음쌍에서는 차이가 없었다.
實驗 Ⅱ에서는 典型的인 자모쌍 내에 境界자모들을 만들어 같은 것끼리 두 範疇로 分類케 하는 分類課題를 사용하였다. 實驗 Ⅱ의 結果도 애매한 형태에 있어 자음조건보다 모음조건에서 ℓ/L比가 매우 작은 것이 밝혀졌다. 자음조건과 모음조컨 모두에서 ℓ/L比는 각기 쌍간에 차이가 있었다.
實驗課題 間의 차이는 자음의 경우는 없는 반면 모음의 경우 생성성과제보다 분류과제에서 ℓ/L比가 훨씬 작았다.
이와 같은 結果는 한글자모를 구성하는 세부특징들간의 길이의 比로 나타낼 수 있는 構造關係가 基本자모에서 派生자모를 構成하는 法則에 따라 다양함을 시사한다. 자음의 경우는 결정적 세부특징적 길이가 문제되지 않으나 모음의 경우는 한글글자의 구정규칙과 모음을 구성하는 규칙 때문에 결정적 세부특징의 相對的 길이가 중요하며 예민한 반응을 보였다.
모음의 경우 實驗課題에 따르는 差異는 모음의 예민성에 기인한 것으로, 분류과제는 세분된 境界시각패턴을 사용하여 판단케 했으므로 예민한 반응이 나타난 반면, 생성과제는 內的表象을 活用케 했으므로 분류과제보다 정확치 못했음을 시사했다.
분류과제에서 境界시각패턴들을 두 範疇로 分類할 수 있었음은 한글자모의 정보처리는 總體情報의 處理가 더 강조되고 있음을 시사하였다.;This paper was an attempt to determine the ratio of distinctive features of some Korean letters. For that purpose, I picked up basic letters (ㄱ,ㄴ,ㅁ,ㅅ,ㅣ,ㅏ,ㅓ,ㅡ,ㅗ,ㅜ) and the corresponding derivative letters (ㅋ,ㄷ,ㅂ,ㅈ,ㅑ,ㅕ,ㅛ,ㅠ) and tried to locate the length point of demarcation between the basic letters and the corresponding derivative letters. The result obtained was believed to show what ratio of distinctive features of the paired letters allow them to be most satisfying. And, employing the generation method and the sorting method, I sought to see whether those ratio given thereby could be generalized.
In the experiment Ⅰ where the generation method was adopted, I gave the subjects a booklet where the initial lines were drawn in each page. And they were asked to finish in each page the paired letters of the most satisfying and the paired letters of the most borderline. The result of the experiment I tends to indicate what follows: the desirable ratio of l/L of the consonants is greater than that of the vowels where L and l represented the length of the initially drawn line and the line drawn by subjects respectively; in the case of the borderline letters, the ratio of l/L of the consonants was longer than that of the vowels as well and there was not any noticable difference in terms of the ratio between the pair of the vowels though the pair of the consonants was seen to have it; and it was recognized that there were distinct differences among the letters of the most satisfying ones.
In the experiment Ⅱ in which the sorting method was used. I provided with the subjects paired letters of various degrees of the borderline from 0 to 1. They were requested to classify them into tow categories, by asking which the letter in question is, the basic or the corresponding derivative. What I came up with the experiment Ⅱ was similar to the experiment I in some respects. In the case of the borderline, the ratio of l/L of the vowels was shown to be smaller than that of the conaonants. And I could see that there were discrete differences among the letters of the desirable ratio. And it could also be observed that the sorting method which depended much on visual process of pattern recognition appeared to suggested that the information processing Korean letters would be more global than local.
Did two experiments show the same result? The answer was mixed. As for the consonants there was not much the gap. But in the case of the vowels, the ratio of l/L was much smaller in the experiment of the sorting method than in that of generation method.
One possible explanation may be offered as to the gap which was, in the case of vowels, observed between the generation method and the sorting method. It concerned with the idiosyncracies of the two methods and of the vowels. While the sorting method allowed the subjects to respond to detailed differences of demarcating patterns in terms of their capacities of visual perception, the generation method left the subject to appeal to their capacities of inner representation. And the vowels were to be recognized as vowels more clearly than the consonants were to be read as consonants, with minute knob. For example, a vowel ㅏ is more readily pointed as such than a consonant ㄱ is.
The result of my studies seemed to indicate that there was not one single ratio which was applicable to all the Korean letters. The ratio of 1/L of each Korean letter varried, depending which basic letter had which corresponding derivative letter. Generally speaking, the consonants tended to be flexible toward the desirable ratio of the distinctive featires of them, whereas the vowels were more likely to fix the determining ratio in them. This was perhaps because the relative length of features of vowels was important due to formation rules of Korean syllables.
