Abstract

<p>　 The purpose of this study was to investigate the basic perceptual abilities related to melody, including pitch and pitch pattern, and the characteristics of strategies used for melody recognition in patients with cochlear implants. A total of 28 adults who developed deafness and underwent CI in adulthood and 34 children who underwent cochlear implantation by three years of age participated in this study. All participants underwent the tasks of pitch discrimination, three-sounds pitch pattern discrimination, and melody recognition. The results showed that the children with CIs performed significantly better than the adults with CI on the pitch discrimination and pitch-pattern discrimination thresholds, while both groups experienced difficulty in identifying melody. Analysis of the melodic confusion matrix showed that the adults with CI frequently made errors within the same rhythm, but different melodies. It was speculated that adults with CI might effectively use the rhythmic cues to integrate melodies they memorized when the hearing was normal. On the other hand, children with CI showed no specific tendency in melodic recognition. The results indicated that the melody that persons with CIs hear and learn may not be the same as those that hearing individuals hear and learn. Multiple regression analysis showed a positive correlation between the pitch discrimination threshold and speech recognition as well as the age at onset of deafness and CI.</p>
