Hearing Loss Research Bibliography

This annotated bibliography was developed to provide research-based support for the communication and language development of individuals who are deaf or hard of hearing (DHH). It includes research about typical language development, language development for children who are DHH, bilingual language development, cochlear implant and hearing aid outcomes, auditory brain development, early intervention, outcomes of Listening and Spoken Language (LSL) intervention, psychosocial development, literacy, and parent choice/coaching.

2018-2024 Annotated Bibliography, Research and Reference List

Compiled by Carol Flexer, Ph.D., CCC-A, LSLS Cert. AVT

This compilation of 70 research articles published between 2018 and 2024 is extremely informative. A number of overall trends reveal:

  1. There are far too many children who use hearing aids and cochlear implants who are substantially behind hearing peers in language, literacy and executive functioning abilities. Study after study document their deficits.
  2. However, the reasons for their delays are also clearly identified: late identification, limited wear-time from day one, poor language environment at home (or at least, lack of an enriched language environment at home), and lack of language evaluations and therapy (especially vocabulary expansion) after 4 years of age.
  3. Most studies do not specify the type of Listening and Spoken Language (LSL) intervention (typically therapy is with unspecified speech-language pathologists), but when Auditory-Verbal Therapy (AVT) is specifically evaluated, outcomes tend to be consistent with hearing peers. Listening and Spoken Language intervention works!
