I didn't get your example on the outperforming in speech... Care to explain?
I didn't say anything about speech. I only said that most likely, Deaf children of Deaf parents (DOD's) will outperform their peers in terms of
language development.
What I really mean to illustrate is how Deaf children express themselves in their 'native' language. Let's stick to English for the time being, as I know you're in a foreign country (Norway?). DOD's will write/read better English generally than their Deaf peers at the same age level. Even those Deaf children who have had the CI implanted early, their language base generally falls short of the levels DOD's occupy in reading/writing English.
Why is that? DOD's acquire native fluency in ASL. Once having a good language base, they apply it in learning other languages such as English, when they do enter formal education, and they do so with ease. Granted, it's not foolproof; there's always a group of DOD's who do poorly with English, just as well as Deaf children doing well with English. There'll always be some CI Deaf children doing well with English and some poorly.
Heck, there were even studies (I can't confirm this, though) that purportedly show regular hearing children, when exposed to some sign language in the household, will do better in mastering the English language later in their infant years. DOD's get this ASL thing in spades from birth!
Now... Back to CI's and their implantation in infants. Yes, the technology has vastly improved and speech processors used today are superior to anything used 5, 10, 15 or 20 years ago. While it's too new, infants implanted with CI's, using state of the art technology, do absorb their native language as used in the household. As a result, CI Deaf children will acquire native fluency in spoken English, just like their DOD peers with ASL. They will have a solid language base, which they can use in their formal education to master reading and writing English, just like their DOD peers currently do.
This is what I'm really getting at; I strongly believe that the CI regimen for Deaf infants in hearing households should be tailored towards language development. A natural consequence of this is that if everything goes well, speech development usually progresses at a normal rate, and any impediments can be corrected in speech therapy later in an educational setting.
Once Deaf children, irregardless of their CI status, having Deaf parents or not, master their native language in its written form, they can do whatever they want and achieve their dreams. I've seen too many Deaf people with impaired English abilities and the costs exacted upon them for their shortcomings, to care otherwise about speech development.
