- Isolation from other people - Isolation within own family - Denied access to interpersonal relationships - Deepened experiential deprivation - Denied informal sources of information |
|
|
What are some Linguistic Implications of Deafness? |
Language acquisition |
|
|
A deaf person's ability to communicate is influenced by such factors as what? |
- If hearing is lost before any language is acquired, it is called prelingual - Amount of residual hearing - Severity of hearing loss |
|
|
How does hearing loss affect speech understanding? |
People with hearing loss often do not hear many of the speech sounds you hear. |
|
|
Sounds such as /s/p/t/f/ and /th/sh/ are difficult to hear because they are voiceless.
T or F? |
TRUE |
|
|
These sounds are clearly visible on the lips such as the short vowels of /i/e/ and /u/ and consonants such as /k/g/ and /h/.
T or F? |
FALSE |
|
|
What sounds look exactly alike on the lips? |
/p/, /b/ and /m/ |
|
|
Hearing aids are amplification devices.
T or F? |
TRUE |
|
|
What does a hearing aid do for the ear? |
- Picks up acoustic signal - Converts acoustic to digital - Amplifies the signal
|
|
|
Instead of amplifying like an hearing aid does, a cochlear implant bypasses the damaged parts of the ear
T of F? |
TRUE |
|
|
How are the internal components implanted? |
Through surgery |
|
|
How do you use the external components? |
- Some can be worn on the body |
|
|
What are some internal components of the cochlear implant? |
- Implant - Electrode array |
|
|
What are some external components of the cochlear implant? |
- Speech processor - Transmitting coil - Battery |
|
|
So how does a cochlear implant work? |
- Microphone picks up sound - Processor selects, analyzes, digitizes, and converts sound into an electrical signal. - This electrical signal is then sent to the electrode array within the cochlea to stimulate the auditory nerve fibers. |
|
|
What are some criteria for a cochlear implant? |
- hearing loss must be bilateral, moderate-to-profound or sensorineural (permanent) - Limited benefit from hearing aids - Poor speech recognition scores - No other medical contraindications - Approval from the cochlear implant team - motivation |
|
|
For a cochlear implant a hearing loss must be bilateral.
T or F? |
TRUE |
|
|
What are some requirements for an Ideal candidates cochlear implant candidate? |
- Plan to use english as a primary language - Will be exposed to spoken language regularly - Have a great deal of support and motivation - Have already had practice listening, hearing |
|
|
What are some limitations of a cochlear implant candidate? |
- Prelingually-deafened teens, adults - No prior exposure to spoken language - Someone who has never learned English - Someone who has been deaf for a long time |
|
|
The National Associate of the Deaf (NAD) supports cochlear implants.
T or F? |
FALSE |
|
|
What is the NAD position statement on Cochlear Implants (2000)? |
- Essentially, cochlear implantation is an individual choice - BUT, those considering it are encourage to learn about all views - Desires a more balance, positive portrayal of Deaf heritage in the media. |
|
|
Cochlear Implants are appropriate for all deaf children or adults.

TRUE |
|
|
The NAD recognizes that parents have the right to make informed choices about cochlear implantation for their children.
T or F? |
TRUE |
|
