This study focused on the comprehension of texts written either in Korean script (Hangul) or Chinese script (Hanja). For this purpose, we measured the reading time and the correct response in text comprehension tasks with 104 Korean-Chinese children who were either 10 or 19 years old. There was a main effect of script : The reading time of Hanja texts was shorter than that of Hangul or Hangul Hanja mixed texts. But the older subjects who spent the same reading time in both Hangul and Hanja texts showed the longer reading time in Hangul Hanja mixed texts revealing the interaction between age and script. The correct response rate on the comprehension task was the highest in Hangul text. The results were discussed in relation to the independent dual language processing systems in Korean-Chinese.

In Korean, as with Kana and Kanji in Japanese, two kinds of word-writing systems--Hangul (the Korean alphabet) and Hanja (the Chinese character; Kanji in Japanese)--have been and still are being used. Hangul is phonetic while Hanja is ideographic. A phonetic alphabet represents the pronunciation of words, wheras ideographs are where a character of a writing system represents a concept. Aphasics suffer from language disorders following brain damage. The reading and writing of Hangul and Hanja by two Korean Broca's aphasics were analyzed with two goals. The first goal was to confirm the functional autonomy of reading and writing systems in the brain that has been argued by other researchers. The second goal was to reveal what difference the subjects show in reading and writing Hangul and Hanja. As experimental materials, 50 monosyllabic words were chosen in Hangul and Hanja respectively. The 50 word pairs of Hangul and Hanja have the same meaning and are also the most familiar monosyllabic words for a group of normal adults in their fifties and sixties. The errors that the aphasic subjects made in performing the experimental materials are analyzed and discussed here. This analysis has confirmed that reading and writing systems are located in different parts in the brain. Furthemore, it seems clear that the two writing systems of Hangul and Hanja have their own respective processes.

In this study of the relationship between preschoolers' visual perception and reading Hangul words, the 287 participants showed significant developmental change in visual perception between three to five years of age. The researcher developed the computer-based screening Test of Visual Perception for Reading (TVPR). Factor analysis confirmed three factors of TVPR : perception of number, direction, and form constancy. These factors correlated highly with four factors of motor-reduced visual perception of the Korean Developmental Test of Visual Perception (Moon et al. 2003). All factors of TVPR explained reading real words and pseudo words; direction and form constancy perception predicted reading low frequency letters. These findings confirm that preschoolers' skills in visual perception contribute to the reading of words in Hangul.

Korean children reading Hangul was studied in children between 2 and 5 years of age. Subjects were 400 young children in each age group from kindergartens or day care centers in 6 cities of Jeon-buk Province. Teachers used a checklist based on Lee, Cha-Suk(2003) to assess children's reading ability. Data were analyzed by frequency, percentage, and $x^2$ using SPSS 10.0 program. Results showed age differences in young children's reading of Hangul. Developmental levels consisted of looking at pictures because of absence of linguistic awareness about words, skipping pages of text without pictures, pronouncing phonemes, being aware of phonemes and of the difference between pictures and print, and knowing that the same phonemes can be applied to different words.

This study was carried out to reveal Hangul acquisition processes in Korean-Chinese children who grow in a horizontal bilingual environment. In this experiment Grapheme substitution/deletion tasks and sensible/non-sensible Kulja reading tasks were administered to 3-, 4-, 5- and 6-year-old Korean-Chinese children growing up in a bilingual environment. Results were that Korean-Chinese children showed similar patterns of Hangul acquisition processes to Korean children but acquired grapheme-phoneme(G-P) correspondence earlier than Korean children. Hangul acquisition rates were 41.7%, 45.7%, 53% and 92.7% at age 3, 4, 5 and 6, respectively. Both Korean-Chinese and Korean children showed higher sensitivity for the final consonant than for the initial and middle consonants. Correlation between phoneme perception and reading was only significant among 6-year-olds in non-sensible Kulja reading tasks. Training in transforming ideographic Chinese to a phonetic system could effect early acquisition of G-P correspondence in Korean-Chinese children.

Causal relationships of kindergarteners' phonological awareness and processing to their ability to read words was investigated with the participation of 289 4- to 6-year-old children attending three kindergartens in Busan. Results showed gradual growth in reading ability with age. Children performed best in reading words and poorest in reading low frequency letters. They showed continuous development in skills of syllable deletion, phoneme substitution, phoneme insertion, phonological memory and naming. Discontinuous development was found in counting syllables. Longer syllables were difficult to count, and middle syllables of 3 syllable words were hard to delete. Children had poor perception of final consonants of Consonant-Vowel-Consonant syllables. Children's phonological awareness and processing were latent variables strongly related to ability to read words written in Hangul.

본 연구에서는 두 가지 읽기 방법으로 저시력인과 정상시력인의 문장 맥락효과를 비교하였다. 실험 1에서는 자기조절읽기(self-paced reading) 방법을, 실험 2에서는 신속순차제시(rapid serial visual presentation) 방법을 사용하여 문장과 무선단어열에서 정상시력 참가자와 저시력 참가자의 읽기속도를 비교하였다. 두 실험 결과에서 저시력 참가자의 읽기속도는 정상시력 참가자에 비해 현저히 감소하였으나, 맥락효과는 읽기 방법에 따라 상반된 양상을 보였다. 자기조절읽기를 사용한 실험 1에서는 정상시력보다 저시력에서 맥락효과가 컸고, 신속순차제시를 사용한 실험 2에서는 저시력보다 정상시력에서 맥락효과가 컸다. 본 결과는 맥락 정보가 처리될 시간이 충분히 허용되는 읽기 상황에서는 정상시력에 비해 저시력 읽기에서 맥락의 역할이 증가하나, 시간적 제약이 주어지는 읽기 상황에서는 반대로 정상시력에 비해 저시력 읽기에서 맥락의 역할이 감소함을 시사한다.

읽기의 초기 단계에서 처리되는 글자의 정보량을 지칭하는 시각 폭은 개별 글자의 획수가 증가하거나 폰트의 종류, 고정된 지면에서 차지하는 잉크의 면적, 글자 간의 간격과 같은 복잡성 요인들에 의해 영향을 받는다. 한글은 자음과 모음들이 조합되는 독특한 알파벳-음절 표기법을 사용하는 글자 체계를 가지고 있어 영어나 중국어를 중심으로 한 결과들에 비해, 자모구성의 글자 유형에 따라서도 복잡성이 달라질 수 있다는 특수성이 있다. 본 연구에서는 세 글자 쌍 패러다임을 이용하여 글자의 유형에 따라 한글 읽기 시각 폭의 크기가 영향을 받는지 살펴보았다. 그리고 여러 글자 유형의 시각 폭 중 읽기 능력의 개인차를 예측하는 글자 유형을 확인해보고자 시각 폭과 읽기 폭, 읽기 유창성, 읽기 이해와의 상관도 살펴보았다. 실험결과, 글자 유형이 복잡해질수록 글자 재인 정확률이 감소하고 시각 폭이 줄어드는 경향이 관찰되었으나 자음+모음+자음의 형태가 자음+모음 형태보다 글자 재인율이 높고 시각 폭도 큰 것으로 나타나 자모조합의 복잡성에 따른 영향이 선형적이지 않고 다른 요인이 개입할 가능성이 관찰되었다. 자음만 제시한 조건과 CV조건의 글자 재인율은 읽기 이해와 정적 상관을 보여 향후 읽기 능력과 관련한 시각 폭 측정 시 사용할 수 있는 글자 유형으로 나타났다.

The purpose of this study was to investigate the causal relationship of kindergarteners' alphabet knowledge to their ability to read words, in connection with the features of the Korean alphabet 'Hangul'. A total of 289 children aged four to six from three kindergartens in Busan participated in the study. The main results are as follows. To begin with, the participants showed continuous development in the knowledge of consonant names, vowel sounds, the vowel stroke-adding principle, and the alphabet composition principle. Meanwhile, discontinuous development was found in the knowledge of consonant sounds and the consonant stroke-adding principle, which indicated that kindergartners could show differential speed in various sub-skills of literacy development. The kindergartners' naming of consonants developed before their recall of consonant sounds, and the knowledge of consonant sounds had an effect on the knowledge of vowel sounds. Children had difficulty in treating more complicated letters of the alphabet stroke-adding principle test, and eve syllables of the alphabet composition principle test. Most importantly, the children's alphabet knowledge was strongly related to their ability to read words written in Hangul, as kindergarteners with a greater knowledge of alphabet names, sounds, and principles were shown to read words better.

한국어 단어의 글자 수, 받침의 수와 위치, 합성어 여부가 기억폭에 미치는 효과를 검증하였다. 그 결과, 전반적으로 글자가 많은 단어일수록 기억폭이 작았으며, 두 글자 단어들에서 받침이 많을수록 기억폭이 더 작았고(기억폭에 대한 받침효과), 합성어보다 단일어의 기억폭이 더 컸다. 단어당 읽기 속도를 측정한 결과, 글자가 많은 단어일수록 속도가 느렸지만, 두 글자 단어들에서 뒷받침단어의 읽기 속도가 받침없는 단어, 앞받침단어 및 양받침단어보다 더 빨랐고(읽기 속도에 대한 말미 받침효과), 합성어보다 단일어의 읽기 속도가 더 빨랐다. 기억폭과 읽기 속도간에 관찰된 이러한 관계는 단어길이효과에 대한 음운루프설명과 잘 부합되지 않으며, 기억폭이 음운정보 뿐만 아니라 시각적 캐시에 표상되는 철자 정보의 영향을 받는다는 설명을 지지해준다.
