The development of intonation in young children with cochlear implants: a preliminary study of the influence of age at implantation and length of implant experience
Year: 2009
Type: article
Abstract: This study describes the development of emerging intonation in six children who had received a cochlear implant (CI) before the age of three years. At the time their implant was activated, the children ranged in age from 11 to 37 months. Spontaneous longitudinal speech samples were recorded from 30-minute sessions in which the child interacted with his or her mother. Data were collected 2 months before activation of each child's CI and at monthly intervals after activation for 6 months. The findings were compared to the typical pattern of early intonation development in children with normal hearing (NH). The results suggested that young CI recipients progress through stages similar to those observed in children with NH. However, the intonation development of children with a CI reflects a marked interaction between chronological age at implantation and amount of CI experience. That is, after 2 months of CI-assisted hearing experience, the older children demonstrated a later stage of intonation development than younger children. These preliminary results support the idea that children acquire some foundations or prerequisites of intonation production through maturation, as measured by chronological age, even without robust auditory experience.
