Abstract

The purpose of this study was to examine changes in the accuracy and range of produced pitch in children with cochlear implants (CI) after an interval-based singing program. A total of three children with CIs aged 5 received twelve 35-minute individual sessions two to three times per week. The interval-based singing program was composed with third, fifth, and eighth intervals and implemented pitch discrimination, pitch imitation, and singing songs with target intervals in a sequence. At pretest and posttest, the changes in accuracy of pitch production during pitch imitation and singing were measured. The results demonstrated that all participants showed improvement in pitch accuracy and produced the target notes with great similarity to the expected pitches in the original song. The range of produced pitch also increased after the program. The results indicate that sequential trials to imitate pitches in a multisensory environment to facilitate the processing of pitch information may reflect how this population perceives pitch information and assist children with CIs to improve their pitch accuracy.

본 연구는 음정 모방 중심 노래부르기 프로그램이 인공와우이식아동의 음고 산출 정확도 및 음고 범위에 어떠한 영향을 미치는지 확인하고자 시행한 사례연구이다. 본 연구에서는 만 5세의 인공와우이식아동 3명을 대상으로 음정 모방 중심 노래부르기 프로그램이 실시되었고 회기 당 35분, 주 2-3회씩 총 12회기의 개별 세션이 진행되었다. 음정 모방 중심 노래부르기 프로그램 동안 3도, 5도, 8도의 목표 음정을 중심으로 음고 변별 - 음고 모방 - 목표 음고를 포함한 노래부르기 활동이 단계적으로 시행되었고, 프로그램 전후에는 음고 모방 및 노래 내 음고 산출의 정확도 변화가 측정되었다. 연구 결과, 3명의 아동 모두 프로그램 참여 후 제시된 음고를 산출하는 정확도가 증가하고 노래부르기 시 산출된 음고가 기대 음고에 유사해지는 것으로 나타났다. 또한 산출 가능한 음고의 범위가 확장됨을 알 수 있었다. 이러한 결과는 인공와우이식아동의 음정 지각 특성을 반영한 단계적 접근과 다감각적 환경에서의 체계적 음악 정보 처리가 학령 전기 인공와우이식아동의 음고 산출을 효과적으로 이끌어낼 수 있음을 보여준다. 더 나아가 본 연구는 음악 지각이나 인공와우이식성인 대상군에 초점이 맞추어졌던 연구 영역을 확장시키고, 학령 전기 인공와우이식아동의 음고 산출 능력 향상을 위해 적용할 수 있는 프로그램을 제안했다는 점에 의의가 있다.
