연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

지금까지의 읽기장애 연구에서는 문자언어 음독의 정확성과 속도 즉 해독(음독)능력에 어려움을 가진 난독증(dyslexia)을 대상으로 한 연구에 초점이 맞추어져 있었으나 최근의 보고에 따르면 음독능력에는 어려움을 가지지 않음에도 불구하고 특수하게 읽기 이해력만이 저하되는 특정 읽기이해부진아동의 사례가 보고되고 있다. 이에 본 연구에서는 음독능력은 저하되지 않으나 읽기 이해력만이 특수하게 저하되는 읽기이해부진 아동과, 음독능력과 읽기 이해력 모두 저하되는 읽기부진 아동의 특징을 비교검토 하였다. 그 결과 읽기부진아동이 음운인식 과제와 음운 작업기억 과제 모두에서 유의하게 낮은 수행을 보인 반면 특정 읽기이해부진아동 집단의 경우 음운 작업기억의 유의한 저하만이 나타나는 것을 확인할 수 있었다. 본 연구결과를 토대로 읽기 이해력 장애아동의 특성에 대한 시사점을 논하였다.

Abstract AI-Helper 아이콘AI-Helper

We assessed reading-related skills in children with reading comprehension difficulties ("Poor comprehenders"), word decoding difficulties ("Poor decoders") and normal readers, matched for age and nonverbal IQ. The reading-related skill tests used in our study are phonological processing, visual proc...

  • Syllable deletion and phoneme onset deletion tests were served as a phonological awareness test. 1) Syllable deletion: In two practice runs and five trials, the children were asked to delete the first, middle, or final syllable from each three-syllable stimulus item and to answer orally. For example, the tester would say ‘What sound would be left if the middle sound is taken away from the /pa.
  • Testing took place in one individual sessions and one group session within a 2-month period. Individual session (Decoding test, Phonologicla short-term memory test, Phonological awareness test, Naming speed test) lasted approximately 20 minutes, and the group session lasted at most 35 to 45 minutes. When the schools were willing to participate, oral and written informed consent was obtained from the curriculum coordinators and classroom teachers.
  • For Korean Hangul, a few research studies have focused on the poor comprehenders who have significant deficits in only reading comprehension. It is insufficient to understand poor comprehenders, because the work in this field has focused on dyslexics and or intervention studies [8]. Thus, in this paper, we clarify the characteristics of poor comprehenders between poor decoders and normal readers in Korean.
  • Nonword repetition test was served as a phonological short-term memory test (1 practice run and 7 trials). The children were required to complete nonword repeeition tasks with stimuli composed of 4 to 10 syllables (CV or CVC structures).
  • ’ The progress of integration and inference are important to read the text, and working memory serves as a buffer for the most recently read propositions in a text, enabling their integration to establish coherency and hold information retrieved from long-term memory[7]. On the other hand, in the results of our study, poor comprehenders did not have significantly lower scores on the Rey -Osterrieth Complex Figure Test (ROCFT) immediate recall and delayed recall tests which were used as visual short-term memory measures. Nation et al.
  • Our purpose of this study was to clarify the characteristics of reading-related skills in children with reading comprehension difficulties (Poor comprehenders), word decoding difficulties (Poor decoders), and normal readers in Korean Hangul. To evaluate these vies, ANOVA were conducted.
  • These tasks were administered in random order to children in the June and July of their first- and second-grade year. Testing took place in one individual sessions and one group session within a 2-month period. Individual session (Decoding test, Phonologicla short-term memory test, Phonological awareness test, Naming speed test) lasted approximately 20 minutes, and the group session lasted at most 35 to 45 minutes.
  • Nonword repetition test was served as a phonological short-term memory test (1 practice run and 7 trials). The children were required to complete nonword repeeition tasks with stimuli composed of 4 to 10 syllables (CV or CVC structures). The children were asked to listen to each nonword carefully and then to repeat the nonword.

대상 데이터

  • A total 285 children were enrolled in our study (Grade 1: n = 112, Grade 2: n = 173). All participants were native speakers of Korean in Daegu Metropolitan City, South Korea.
  • A total 285 children were enrolled in our study (Grade 1: n = 112, Grade 2: n = 173). All participants were native speakers of Korean in Daegu Metropolitan City, South Korea. All of the children attended the same school serving of Education curriculum.

데이터처리

  • The group differences were assessed using a Tukey’s post hoc test if the ANOVA was significant.
  • Z-scores of each grade of the all tests were used in this study due to each reading groups composed not only Grade 1 but also Grade 2. Z-scores of three reading groups were compared separately using one-way ANOVA tests. The group differences were assessed using a Tukey’s post hoc test if the ANOVA was significant.

이론/모형

  • The Rey-Osterrieth Complex Figure Test (ROCFT) with copy drawing, immediate recall, and delayed recall was used in order to assess visual information processing abilities. The ROCFT has been used for the assessment of visuoconstructional drawing ability and visual memory [39].
