Q

How should you select a speech test for children?

A

Degree of hearing loss should not be a factor
Tests should be selected based on the individual child’s language capabilities
Profound hearing loss makes it harder for children with hearing aids to receive information through hearing, though this may not apply with children with CI’s

Q

What are the different ways to evaluate speech perception (4)?

A

Detection: ability to tell when a stimulus is present (just like tones but with speech)
Discrimination: ability to determine whether two stimuli are the same or different (cat vs hat)
Identification: Ability to recognize and label stimulus (name thing and they have to select it)
Comprehension: ability to understand what the stimulus means

Q

What is the speech awareness threshold test?

A

A test that uses speech stimuli to determine threshold—the lowest level at which a person can detect the presence of the stimulus 50% of the time.
Establishes a minimal response level for awareness for speech
Response can vary greatly from eye widening, head turn, or facial change
Stimuli can be the child’s name, nonsense words, or short phrases
Stimuli is presented typically via MLV and can be obtained in the SF (better ear response) or under headphone

Q

What is the CRISP jr?

A

Evaluation of speech thresholds in quiet and in noise in children ages 2.5 years and above (3-5 typically, then onto the CRISP)
Computerized application uses 4-alternative forced choice
Select correct image, music as reinforcement (entertainment with positive)
Monosyllabic words and the take is easier

26
Q

What is the CRISP?

A

Children’s realistic inventory of speech perception
Used on children older than 5
Closed set spondee test using a picture book or computer
Need to make sure that the child knows the words being tested
Evaluation of speech thresholds in quiet and in noise in children ages 4 and above
Computerized application uses 4-alternative forced choice
During testing, children are engaged in a computerized game such as puzzles

27
Q

What is bone conduction SRT?

A

Useful for diagnosing CHL in young children by comparing to AC SRT
Used with a 2- to 4-year-old child who has bilateral ear canal atresia or microtia in order to determine the hearing status of the cochleae
Speech signal is more meaningful for children and other hard-to test children than pure tone stimuli
Has high correlation to PTA by BC at 500, 1000, and 2000 Hz

28
Q

What are some limitations to bone conduction SRT?

A

Speech through bone oscillator is not usually calibrated
Range is limited

29
Q

What are speech recognition tests for children?

A

Designed to evaluate a child’s ability to understand speech under different listening conditions
Performed at suprathreshold levels at different at different intensities and under varying conditions of competing noise
AKA word recognition, word discrimination testing, or speech intelligibility testing
Several variables can affect the outcomes of speech perception tests

30
Q

What is the level of presentation for speech recognition tests for children?

A

30 dB SL re: SRT for normal hearing listeners
40 dB HL re: SRT for listeners with a hearing loss
Steeply sloping losses may require a higher presentation level than 40 dB SL the goal being to make the stimuli audible
Stimuli also can be presented at MCL

31
Q

Is masking almost always indicated for WRS for an asymmetric loss?

A

Yes

32
Q

What is the recommended scoring for speech recognition tests?

A

90-100% - Excellent
80-89% - Good
70-79% - Fair
< 70% - Poor

33
Q

How do you select the correct speech recognition test for a child?

A

Selection depends on child’s vocabulary level and ability to cooperate
Degree of hearing loss should not be a factor in selecting tests
Using inappropriate vocabulary in speech perception tests can yield misleading results

34
Q

What is an open set for speech testing?

A

Offers no clue
The child may repeat without understanding
More difficult
Will yield lower test results
Offers a more realistic picture of speech perception capabilities in real conversation
Should be attempted by the age of 5

34
Q

What is a closed set for speech tests?

A

Limited number of items from which the child needs to choose
May be numbers, body parts, pictures or alphabet
Guessing is still a possibility

35
Q

What is phonemic scoring?

A

There exist some test relying on phonemic scoring
Gives information on which frequencies seem to be impaired perceptually
Vowel errors: indicate insufficient low frequency information
Sibilants error: insufficient high frequency perception

36
Q

What is whole-word scoring?

A

Most of the tests used have norms according to whole word scoring
Even if 1 phoneme in a word is wrong (ex: sox vs fox) the whole point is deducted

37
Q

When do you want to use recorded speech?

A

Has the advantage of being more reliable and easily comparable test-retest but can be time-consuming and challenging for a child, requiring breaks between stimuli, repetitions due to distractions, and timeouts for encouragement
Standard

38
Q

When do you want to use MLV?

A

Only used when recorded testing is not available (according to AAA)
It can potentially overestimate a child’s auditory function
More interesting to listen to for young children

39
Q

What are some characteristics of a full word list?

A

Reduces the chance of scoring errors
Increases reliability
Time consuming
25 words allow a good evaluation of the child’s auditory function

40
Q

What are characteristics of a half word list?

A

Use it only when the word list is validated to be used with fewer number of words
10 words are not enough unless you are using the isophonemic word lists where you will be scoring on phonemes
Considering your word is a CVC: then you have 3x10=30 points

41
Q

Why do you use a carrier phrase?

A

Alerts the child to attend
Places the word in a sentence context that more accurately represents its use in normal conversation

42
Q

Carrier phrase examples?

A

Show me…
Tell me…
Point to the…

43
Q

What is the early speech perception test?

A

Two formats (standard version and a low-verbal version that uses objects)
Can be used in children as young as 3 years old who are profoundly Deaf

44
Q

What does the early speech perception test include?

A

Pattern Perception (Subtest 1)
Spondee Identification (Subset 2)
Monosyllabic Word Identification (subset 3)

45
Q

What is the mr. potato head task?

A

Modified open-set
Requires child to manipulate toys in response to instructions presented in the auditory-only modality (put a hat on Mr. Potato Head, make Mr. Potato Head go to sleep)
Ten instructions are presented and scored on the basis of the number of key words correct (out of possible 20) and sentences correct (out of possible 10)

46
Q

What is nu chips?

A

A closed-set picture pointing word recognition test
Scored as percentage
Age range 3-5
Can be administered as an open-set by not using picture book
50 monosyllabic words
Two recordings: one male and one female talker

47
Q

What is the word intelligibility by picture identification (WIPI) test?

A

One of the most commonly used
Consists of picture plates, each with six images
Four images have rhyming words, and two serve as distractors to reduce the probability of a correct guess
Appropriate for children whose language age is between 5 to 8 years
Can be measured as open-set by not using picture book
Can be performed auditory only or auditory and visual

48
Q

What is the phonetically balanced kindergarten word list (PBK-50)?

A

Fifty-item, phonemically balanced, monosyllabic word lists selected from the spoken vocabulary of normal hearing kindergarten children
Age range 5 to 8 years
Open set
Scored as percentage
Requires a verbal response

49
Q

What is the BKB-SIN?

A

The BKB-SIN can be used to estimate SNR loss in children ages 5+ years and adults for whom the QuickSIN test is too difficult
Quick and easy to administer and score
Indicate ability to understand in noise

50
Q

Do children require the same SNR as adults?

A

No, they need a higher SNR
SNR improves with age
Scores on the BKB-SIN will be different than the QuickSIN

51
Q

Why are children more affected by SNR loss than adults?

A

They are still developing their linguistic and world knowledge, essential for speech perception
Test results for children should be interpreted individually, taking into account factors like the child’s speech, language, and academic abilities, as well as the learning environment, including class size, room acoustics, and teaching methods

52
Q

What should happen as a child’s vocabulary increases and improves?

A

The more difficult the tests should be
Allows comparison with normal-hearing peers

53
Q

What test protocol should you use for a language age of >8 years?

A

CNC or NU6

54
Q

What tests should be used for a child with a profound loss who does not have access to auditory information with technology?

A

Closed set
Only used when the child cannot perform standard tests
ANT
Early Speech Perception (ESP) Test
Mr. Potato Head Task
Alphabet Test
Minimal Auditory Capabilities (MAC) Test
Test of Auditory Comprehension (TAC)

55
Q

What is the auditory numbers test (ANT)?

A

A simple auditory test to determine whether a young child with hearing loss can perceive spectral aspects of speech or only gross temporal acoustic patterns
Tests numbers perception
Number identification relies mostly on vowels therefore it is mostly testing low frequencies
Used with severe to profound hearing loss or those with low vocabulary level

56
Q

Should speech perception be assessed both aided and unaided?

A

Yes

57
Q

Do real-ear measurements reveal how well the brain interprets sounds or the child’s hearing performance?

A

No

58
Q

How do you test speech audiometry both aided and unaided?

A

To assess a child’s day-to-day performance and to determine if the child hears enough speech information with their technology, measure speech perception in soundfield at normal (50 dB HL/~ 65 dB SPL]) and soft (35 dB HL/~ 50 dB SPL) conversational levels in quiet as well as conversational levels in noise (50 dB +5 signal-to-noise ratio [SNR])

59
Q

When should you attempt to do open set with a child?

A

Age 5 if there is no cognitive or developmental delay
