Effects of Early Cochlear Implantation on Hearing Mother-Deaf Infant Relationships and Language Development

This study investigated changes in language techniques and manners of maternal speech influenced by the level of auditory experiences of children with cochlear implants. The mothers employed language techniques such as comment, linguistic mapping and directive shortly after implantation. As the children gained auditory experiences, the mothers changed their strategies by decreasing the use of the former techniques and increasing the use of parallel talk with increased MLUw. In addition, they produced exaggerated intonation, appropriate turn-taking and pausing which indicated reciprocal communication between them. The selection of the language techniques and manners of maternal speech was affected by the children's auditory experiences rather than chronological age. The result suggests this would be one of the effects of early cochlear implantation.
