Question

I am looking for research that focuses on implants and listening age. For example if a child was implanted at the age of 3 1/2 and has been in school, and intelligence appears age appropriate, should the child be listening/ processing information at their

Answer

The concept of listening age is a very helpful one clinically, but remember, it is only a clinical guideline, rather than a standardized way of evaluating progress. Basically, a child "ages" or matures in listening once she has access to sound via a cochlear implant. So, a child who has had an implant for 3 1/2 years would be expected to demonstrate auditory skills similar to a 3 1/2 year old, not a six year old. 3 1/2 years of auditory experience can rarely compare to a normal-hearing child who has had 6 years of auditory experience.

However, there is another issue here, and that is language proficiency. Auditory development and language proficiency are not the same thing. If a child has been listening for 3 1/2 years, and has a language age equivalent of a 3 1/2 year old, we would only expect her to perform on language tasks (like the comprehension-of-a-passage task you mentioned) at the 3 1/2 year level. Before evaluating your child for a processing disorder, I would suggest you seek a thorough assessment of her language comprehension and production by a speech-language pathologist familiar with the communication development of implanted children. In particular, the assessment should determine how your daughter handles lengthy and complex linguistic information in a face- to-face, not auditory-only, situation. That will tell you what her maximum language abilities are at present.....her language ability in an auditory-only situation will likely be somewhat lower than that.
