Word Rec Testing Intro Flashcards
What is included in a basic audiologic assessment?
case history
otoscopy
immitance testing
speech threshold testing
puretone testing
suprathreshold speech testing (word rec)
documentation and coding
other tests
what is differentiated during pure tone testing
differentiates middle ear from sensori/neural
other testing differentiates what
sensori (cochlear) vs. neural (auditory nerve)
how do we know we got valid test results?
test-retest reliability (1,000, within 5dB) - checking to see if they are giving valid responses
equipment is calibrated
daily bio checks/weekly
make sure PT understands the test task
use masking as needed
SRT is in agreement with PTA
What agreement do we want with PTA?
plus or minus 10
What is included in PTA
500, 1000, 2000
cross check principle
SRT is used to check PTA thresholds
air bone speech
air bone and SRT and WRS
word rec in quiet
suprathreshold testing
what is PB max
best ability/score the patient can do
what does PB stand for
phonetically balanced
3 components of evidence based practice
client perspectives
clinical expertise
external scientific evidence
what are the 3 aspects of any diagnostics
test stimuli and set-up – what patient experiences
How to do the test correctly
How to interpret findings
identifying the site of lesion
diagnostic testing
what test can point to a site of lesion?
test stimuli for SRT?
spondee words
test stimuli for pure tones?
pure tones
pure tones (air and bone)
middle ear or retrocochlear
differentiate cochlear vs retrocochlear
word rec
percent correct
wrs
threshold measure
SRT
percent correct of a given suprathreshold level
WRS
Other names for wrs
Word recognition
WRS
PBmax
Speech discrimination (old term)
Discrimination score
clincial uses of WRS testing
diagnostic and treatment
compares word rec ability over time
diagnostic
site of lesion testing (cochlear vs retrocochlear)
diagnostic WRS
General sense of impact of hearing loss on speech understanding
wrs treatment
One test to identify monaural vs. binaural amplification
wrs treatment
Compare unaided vs. aided
wrs treatment
used in ci candidacy
wrs treatment
speech material for WRS?
single words (monosyllabic, CVC)
Phonetically balanced word list (recorded 50 list)
frequently presented with carrier phrase
homogeneous (familiarity, word structure, emotional loading)
can be closed or open set
refers to speech tests using single words
closed vs open set test
what is closed set
Possible response choices are limited
Single digits
Picture-pointing or paper and pencil tests with limited number of foils
Familiarized spondee list
what is open set
Possible response choices are one of many words with no context
Spondee list that is not already familiar
Single-syllable words
closed number of word sets
closed set
familiarized patient with list
closed set
any word randomly
open set
no context for the words or no familiarization
open set
Test materials are single-syllable digits (and listener is advised of this)
closed
Test of one-syllable words with the structure CVC
open
SRT after familiarizing with 8 words
closed
SRT without familiarizing
open
WRS where a patient is shown 6 pictures and has to identify the correct one
closed
can you compare closed and open set scores?
no because closed set will have better scores
How are word recognition scores used diagnostically?
to determine site of lesion (cochlear/retrocochlear)
compare over time if it is changing (only correctly and same word list etc.)
What are the three components of evidence-based practice?
client perspective
clinic expertise
external scientific evidence
How are word recognition scores used in audiologic treatment?
general sense of how their hl affects their speech understnading
determine monaural vs binaural and which ear
CI candidacy
List several characteristics of the speech materials used for WR testing.
monosyllabic
pb
cvc
closed or open set
homogeneous
*same frequency and familiarity to the PT, same structure, not emotionally loaded
What does it mean to say a word list is phonetically balanced?
has all of the sounds (phonetic) from the language in the word list
Differentiate between open set and closed set. Which one is easier, meaning which one would yield a higher percent correct score?
closed is easier
closed is choices to choose from in terms of a response
open anything goes
are WR scores tests of communicative function?
no
How might a PBmax score underestimate a patient’s functional receptive abilities? reasons why someone may miss words when they wouldn’t usually?
no cue or redundancy/no context (say the word pig misses but if you say my daughters fav farm animal is pig, gets it)
no visual cues (lip reading)
established monaurally and convo speech is processed binaurally (binaural advantage)
no binaural advantage
How might a PBmax score overestimate a patient’s functional receptive abilities?
why does someone do better than they normally would?
quiet, no competing noise with sound treated room and convo is usually in noise
done at a high level compared to conversational speech
WRS Test parameters:
suprathreshold pL
recorded materials
word list
expressed as percent correct
obtained one ear at a time in quiet
full word list
50
half word list
25
If masking noise is used in the non-test ear during WRS, is it considered speech in noise testing
NO
what is a performance intensity function
psychometric function, performance level (presentation level) on x axis and performance on the y axis (%)
at very close to threshold we get very low scores and the higher you go the better the score gets
what is pb max
pb max an individuals best performance on a phonetically balanced word list
USE SPRINT CHART
pta 36
wrs 60
Not at the PT’s PB max and needed at another level
USE SPRINT CHART
pta 32
wrs 80
yes it is likely we got the pb max
