Research
- Early Hearing Detection and Vocabulary of Children with
Hearing Loss
- EHDI guidelines:
- 1 month: hearing screening
- 3 months: diagnosis
- 6 months: intervention
- 448 children with bilateral hearing loss in 12 states at 8 – 39 mos.
- RESULTS:
- Only 1/2 to 2/3 of participants met EHDI 1-3-6 guidelines
- Vocabulary below average
- “… many children with hearing loss fail to keep pace with the exponentially
increasing vocabulary growth demonstrated by hearing children as they move beyond 18 months of age (i.e., from producing an average of 9 words per month to 40 words per month)” (p.7)
- Decrease the age at which children are identified

Research
- Early Sign Language and Cochlear Implantation
Benefits
- Use sign language with CI’s?
- 97 children
- Results: Children without early sign language exposure:
- achieved better speech recognition skills over the first 3 years post
implant
- exhibited a statistically significant advantage in spoken language
and reading near the end of elementary grades
- produced more intelligible speech
- “Over 70% of children without sign language exposure achieved age-
appropriate spoken language compared with only 39% of those exposed for 3 or more years. Early speech perception predicted speech intelligibility in middle elementary grades” (p. 1)
- “English communication and literacy is the primary objective for a shild
with a CI, focus on early spoken input increases the probability of achieving those goals” (p.8)
