Children were enrolled from 6 cochlear implant centers and 2 pre-schools between November 1, 2002 and December 31, 2004.
  • 188 children with cochlear implants—mean age = 2.2 years at enrollment
  • 97 children with normal hearning÷mean age = 2.3 years at enrollment
Children are assessed at their clinic every 6 months in the first 3 years and then every 12 months in the next 5 years. We are currently conducting 4 and 5 year annual visits.

Assessments include:
  • Standardized language tests to see how children understand and use spoken language
  • Routine hearing and speech evaluations
  • Play activities that are video-taped
  • Questionnaires for children, their parents, and their teachers
