Q

Deprivation for people with HL

A

Auditory and social auditory deprivation (less time talking with others)

20
Q

Rat deprivation study

A

Less dendritic branches

Monaural deprivation led to impaired binaural skills

21
Q

ABR

A

Measures EEG activity in response to auditory stimulation

Measures latency and amplitude of waves

22
Q

Latency

A

How long it takes a wave to appear (milliseconds)

23
Q

Critical period biology and social

A

Myelination of neural tracts

Socially acceptable period for certain stage (ex: babbling)

24
Q

Average words per hour presented to HH/D child

A

Professional family 2100

Working class 1200

Welfare 600

25
Q

Mainstreaming faulty assumptions

A

Physical placement of HH with NH means more social interactions

Physical placement of HH with NH leads to more social acceptance by NH

Mainstreamed HH will automatically imitate NH peers

NH parents will allow mainstreamed children in classroom

26
Q

Mainstreaming keys to success

A

Social skills and clear communication

Parental support/involvement

Integration through sports, clubs

Structured teaching of social skills

27
Q

Mainstreaming levels

A

1-exceptional children in regular classes w/ or w/o supportive services

2-reg class attendance plus supplementary instructional services

3-part time special class

4- full time special class

5- special stations

6- home bound

7- instruction in hospital, residential, or total care settings

28
Q

Reasons to mainstream

A

Prepare for life in society (real world)

Learn from others (observation/imitation)

Normal experiences (vibrancy/excitement of reg schools)

Change attitudes (overcome prejudices)

Teach democracy

Challenge exclusions

29
Q

Frequency of aud evals

A

Age 0-3: every 4 mos

Age 3-6: every 6 mos

Greater than 6: every 12 mos

30
Q

SAT

A

Speech awareness threshold

Lowest intensity level at which presence of speech signal can be heard 50% of the time

31
Q

SRT

A

Speech recognition threshold

Lowest intensity level at which person can correctly recognize (repeat/perceive) speech signal 50% of the time

32
Q

Word recognition

A

Discrimination task: ability to repeat monosyllabic words at a comfortable loudness level

Clarity/ability to understand speech

33
Q

PBK words

A

Phonetically based kindergarten words

Monosyllabic

34
Q

WIPI

A

Word intelligibility by picture identification test

35
Q

DIP

A

Discrimination by identification of pictures

36
Q

HH child mainstreaming advantages

A

Person first, then disability

Learn to take risks (contribute to discussion)

Talk to peers as equals

Know who they are and where they stand

37
Q

HH parent mainstreaming advantages

A

Clearer picture of child’s abilities/limitations via comparative observation

Not further handicapped by abnormal surroundings

Friendships with hearing peers in unselfconscious way

Friendships with parents of hearing children based on common problems (age/interests)

38
Q

Hearing peers advantages of mainstreaming

A

Labels of deafness are “far out”

2 way street: they give and receive help

Take advantage of opportunities to work and socialize

39
Q

Inverse square law

A

Sound intensity drops by 6dB for each doubling of distance from source

40
Q

ITD and IID

A

Interaural time difference

Interaural intensity differences

41
Q

Binaural advantages

A

Localization

Understanding speech in noisy background

42
Q

Monotic

A

Listening through one ear

43
Q

Diotic

A

Both ears stimulated, but receive same signal

Ex: body aid with y-cord

No localization, speech in noise, ITD or IID

44
Q

Dichotic

A

Both ears stimulated and receiving different signals simultaneously

Takes advantage of ITD and IID

45
Q

3 mic settings for FM

A

Environmental

Teacher
