  • The purpose of this study was to examine how a singing program using self-voice monitoring for children with cochlear implants (CI) influences on the intonation and the accuracy of pitch production. To verify and estimate the effectiveness, a program was conducted with participants of 7 prelingual CI users, whose aged between 4 years and 7 years. The program adopted three stages from the self-voice monitoring: Listen, Explore, and Reproduce (LER stage). All participants received 8 singing sessions over 8 weeks, including pre-test, intervention, and post-test. For the pre and post-test, participants' singing of an excerpt of a song "happy birthday" and speaking three assertive sentences and three interrogative sentences were recorded and analyzed in terms of the intonation slopes at the end of the sentences and the melodic contour. From the sentence speeches, we found that the intonation slopes of the interrogative sentences significantly improved as they showed similar patterns with that of the average normal hearing group. Also, in regard to singing, we observed that the melody contour had progressed, as well as the range of pitch production had extended. The positive result from the intervention indicates that the singing program was effective for children with CI to develop the intonation skill and accuracy of pitch production.

  • The relationships between the ability to understand changes in meaning depending on the prosody of spoken words and the ability to perceive pitch and melodic contour in cochlear implants (CI) recipients were examined. Fifteen postlingual CI recipients were measured in terms of speech prosody perception, speech perception, pitch discrimination (PD), and melody contour identification (MCI). The speech prosody perception test consists of words with positive (PW) and neutral meaning (NW). Participants were asked to identify the meaning of words depending on the conditions of positive and negative prosody. The MCI consists of subtests 1 and 2 with different chance levels to choose. Then, the relationships between speech prosody perception, speech perception, PD, and MCI performance were analyzed. There was a significant difference in identifying the meaning of words expressed in a different prosody between the PW and NW conditions. Speech prosody perception showed a significant correlation with MCI 1 while there was no significant relationship with speech perception. Although speech perception may be possible after CI, limited spoken word comprehension due to decreased sensitivity for prosodic changes may persist in CI recipients. In addition, there was a limitation in perception of melodic contour change compared to pitch discrimination, which is related to speech prosody perception.

  • The purpose of this study was to investigate how children with cochlear implants (CI) perceive emotion in music depending on mode and tempo cues, and to compare them to NH children. Participants in this study included 13 CI children who were implanted with either unilateral or bilateral cochlear implants aged between 7 and 13 years, 36 NH children, and 20 NH adults. The musical stimuli used in this study were piano recordings in either major or minor mode, with tempos of 130 bpm and 56 bpm. A comparison of the emotion perception levels of NH children and NH adults before the experiment showed that there was no significant difference between the two groups. Meanwhile, the way they perceive different emotions from each music condition varies, in that CI children perceived all music conditions except as happy, while NH children perceived music in a major key as happy and music in a minor key as sad. It supports that CI children tend to rely primarily on tempo cues to process and identify emotional information from music, which is contrary to NH children. It is important to note that this study enhanced and specified the understanding of how CI children perceive music emotion and use specific musical elements in the process. These findings indicate baseline data on emotion perception in music in CI children.

  • Purpose: The aim of this study was to develop an educational program for the children's guardian with cochlear implants in order to provide knowledge and information about cochlear implants. Methods: The educational program was developed based on a literature review, potentially relevant website analysis, and validation by an expert group. Two out of twenty-two educational items under four domains that had item-level content validity index (CVI) greater than 0.8 by the ten experts were finally selected and used. After the children's guardian participated in this educational activity through a specially designed booklet and DVD, the effectiveness of the program was evaluated. Results: A total of 8 children's guardian participated in the program. Their knowledge levels significantly increased after participating the program (mean $15.0{\pm}3.02$ vs. $19.0{\pm}0.93$, Z= 2.371, p=.018). Satisfaction levels with the program was high, $4.1{\pm}0.87$ out of 5. Conclusion: This newly developed educational program for the children's guardian with cochlear implants is proved to be effective and can be used in nursing practice. In addition, the participants seemed to be satisfied with the program. Furthermore, this program may also improve the effects of adult with cochlear implants.
