ABSTRACT
This study investigated the effects of age at time of testing, hearing history (age at hearing loss) and hearing status on melody recognition. Four groups were compared: children with normal hearing thresholds, and three groups of cochlear implant recipients (children with prelingual deafness, children with postlingual deafness, adults with postlingual deafness). Participants were tested for recognition of familiar melodies (no lyrics) in a closed-set task. Groups differed in accuracy in the following rank order (most to least accurate): children with normal hearing thresholds, adult cochlear implant recipients, children with postlingual deafness, children with prelingual deafness. Melody recognition scores were correlated with age, variables regarding hearing history, musical background/experience and speech perception scores.
ABSTRACT
The purpose of this study was to compare song recognition and song appraisal of children (ages 8-15) who use cochlear implants and normally hearing children. The Iowa Music Perception and Appraisal Battery-Children's Version was developed to measure these differences. Fifteen children who use cochlear implants and 32 normally hearing children participated in this testing battery. The battery includes a Song Recognition Test, a Song Appraisal Test, and a Musical Background Questionnaire. The cochlear implant recipients were significantly less accurate (p <.0001) than normally hearing children on the Song Recognition Test. Cochlear implant recipients also demonstrated greater dislike than normally hearing children for all items on the Song Appraisal Test. Despite these differences, cochlear implant recipients were quite similar to normally hearing children in terms of self-reported informal musical involvement and music listening habits.

The purpose of this study was to compare the effect of structured training on recognition and appraisal of the timbre (tone quality) of musical instruments by postlingually deafened cochlear implant recipients. Twenty-four implant users (Nucleus CI24M) were randomly assigned to a control or a training group. The control group experienced only incidental exposure to music in their usual daily routine. The training group participated in 12 weeks of training delivered via a laptop computer in which they were introduced to excerpts of musical instruments representing three frequency ranges and four instrumental families. Those implant recipients assigned to the training group showed significant improvement in timbre recognition (p < .0001) and timbre appraisal (p < .02) compared to the control group. Correlations between timbre measures and speech perception measures are discussed.

The purpose of this study was to compare melody recognition and pitch perception of adult cochlear implant recipients and normal-hearing adults and to identify factors that influence the ability of implant users to recognize familiar melodies. Forty-nine experienced cochlear implant recipients and 18 normal-hearing adults were tested on familiar melody recognition. The normal-hearing adults were significantly (p < 0.0001) more accurate than implant recipients. Implant recipients showed considerable variability in perception of complex tones and pure tones. There were significant negative correlations between melody recognition, age at the time of testing, length of profound deafness and complex-tone perception, and significant positive relations between melody recognition and speech recognition scores.
