Term
feedback
Definition
Component of communication process in which cues are provided to the speaker while producing speech, allowing opportunity for necessary adjustments or corrections.
Term
suprasegmentals

rhythm, rate, and intonation of speech is referred to as
Term
20-20,000 Hz

true
Term
audiogram
Definition
most single useful predictor of a person's speech perception abilities
Term
transitional cues

production of a speech sound, or phoneme, is often influenced by the surrounding sounds in the speech production.
Term
agressive conversational style

a listener who blames others for communication difficulties
Term
repair strategy
Definition

analytic approach
Definition
auditory training approach that attempts to break speech into smaller components such as phonemes or syllables
Term
redundancy
Definition
conversational speech can be described as containing info from a variety of sources available for a listener to determine meaning. This predictability refers to concept of:
Term
auditory training goals for typical adult
Definition
1. adjustment and orientation to the hearing aid
2. learning to maximize auditory cues for the perception of speech

approaches for auditory training
Definition
*analytic

*assertive (positive)
Term
linguistic constraints available to enhance speech perception
Definition
1. syntactic- every language governed by rules for grammar, specifies relationship between words
2. semantic constraints-words used in a sentence are usually related to one another in meaningful way
3. situational-language usually takes place within a physical & social context. (i.e. football game, religion wouldn't be discussed typically).
2.
Term
4 major steps/objectives for AT for kids w/prelingual deafness
Definition
1.development of the awareness of sounds
2.development of gross dsicriminations
3.development of broad discriminations amoung simple speech patterns
4.development of finer discriminations for speech
Term
intensity/loudness
Definition
differences that a child perceives in the stress of a particular syllable
Term
duration
Definition
one of the 1st cues that children w/ HL perceive, seperating up, up, up from weeeeee
Term
frequency
Definition
intonational melody that communicates whether an utterance is a question or a statement
Term
child's "listening age"
Definition
calculated based on age at which child begins hearing aid/implant use
Term
According to Cole & Flexer, the primary context for developing spoken language is:
Definition
everyday interactions w/caregivers using spoken language
Term
theory of mind
Definition
ability to recognize the perspective of another
*incidental language learning is essential for developing TOM
Term
executive functions
Definition
a collection of self-regulatory and management functions, including planning, organizing, & problem solving
Term
consistent use of appropriate amplification
Definition
Cole & flexer: the most important and initial step for parents is in the development of spoken language for children who are deaf is:
Term
strategies to improve interaction at home for toddler w/ HL
Definition
*use of FM system
*background noise
*decreasing distance from child
Term
selective attention
Definition
child is playing with noisy block and alerts when his name is called by pausing and searching. Example of:
Term
speech detection threshold
Definition
threshold of awareness
Term
speech recognition threshold (srt)
Definition
threshold of accurate responses to spondee list
Term
speech discrimination testing
Definition
word recognition score
-presented at comfy level
-phonemically balanced list
-represented as a percentage
-can be modified w/presentation using diff levels, visual cues, and noise
Term
otoacoustic emissions
Definition
used as a screening primarily in infants
-measurement of acoustic by-product of outer hair cells of cochlea; correlated w/ norm hearing
Term
auditory brainstem response (abr)
Definition
-diagnostic tool, used when behav responses cant be obtained
-recordings made at diff intensities
-intensity decreases, latency of response increases, & amplitude of waves diminish
-audiometric threshold is minimum intensity needed to obtain clear wave
Term
hearing loss characteristics
Definition
-time of onset (preling,postling, deafened)
-type of loss (conductive, sensorineural, mixed, functional/non-organic, central audit processing disorder)
-auditory speech recognition ability (strong indicator of function, spch discrim tasks, phonemic regress w/ age possible, not really correlated w/hearing sensitvity)
Term
consequences of HL
Definition
-Primary: impact on oral communication
-Secondary: educational, vocational, psychological, social
Term
Hearing Disorder Classification
Definition
Hearing isnt functionally normal, there is disorder w/ 3 dimensions:
1. impairment of function
2. activities (communication) restricted
3. participation w/in life situations limited (ex: cant get job)
Term
Affects of Unilateral HL
Definition
-sound localization
-hearing in noise
-cognitive load
-loudness summation
-HEAD SHADOW EFFECT: sound must travel to other ear
Term
TEHDI
Definition
1. Newborn Hearing Screening- OAE @ birthing center
2.Follow-up Hearing Scr: OAE by 1 mo
3.Diagnostic Testing: ABR by 3 mos
4. Referral to Early Int: ECI @ 2days & LEA @ 5days.
5. Assessment, Eligibility, & IFSP: by 45 days
Term
audiological deafness
Definition
-bilateral, profound, sensorineural loss.
Term
A mild hearing loss...
Definition
has implications for learning
Term
What percentage of kids w/ a mild hl fail @ least 1 grade?
Definition
37%
Term
incidental lang learning
Definition
just so happen to learn language, not intentional
Term
hearing aid affect
Definition
presence of HA elicits negative perceptions
Term
missing language =
Definition
incomplete self-concept
Term
what is the difference between antidotal and an empirical response to this question?
Definition
antidotal:story about successful case; need to take into consid research and fact that 1 good case doesnt rep entire population
Term
T/F:bc of concomitant (happens @same time) lang deficits, kids growing up w/ hl may have limited experience in self-expression & a subsequent delay in awareness & understanding of their own emotions as well as emotions of others.
Definition
True
Term
Why would kids w/ hl be "less accurate in id-ing emotional state of others" or "have poorer understanding of affective words"?
Definition
if they cant explain/express their own emotions, they cant explain emotions of others.
Term
what are the affects on family & peer relationships?

-maintaining healthy relationships
Term
Reactions to Acquired HL (4)
Definition
-anger/anxiety
-conversational exclusion
-role shifts w/in fam
-social w/drawal & depression
Term
When HL effects you @ work it can lower income because...
Definition
you miss speech; ppl w/ profound hl typically make less $$$
Term
deafened personality
Definition
-deafened ppl cant control life w/ language; use their actions to control things; are typically organized
Term
who would provide counseling services? In what context?
Definition
teachers, audiologist, early intervention specialist...
Term
What's the difference between counseling and psychotherapy?
Definition
C- coach & guide
Psy-focuses on personality

vents, dampers, horns
Term
Good Fit of HA
Definition
-reduces feedback
-ensures comfort
Term
ways to evaluate HA
Definition
-fitting software
-electroacoustic analysis
-real ear:uses probe mic measurements
-low tech:family's feedback overtime
-inital patient patient data required: pure tone thresholds, loudness discomfort level, spch/spch in noise
Term
binaural fittings can provide (4)
Definition
1. better hearing in noise
2. improved discrim
3. some (5-10dB) improved sensitivity
4. reduced fatigue
Term
