Q

Should you start with speech stimuli during CPA?

A

Yes, if they respond to speech
May make it more interesting for the child
Condition to listen and drop task

Q

What should you start testing with?

A

A task that requires the least amount of cooperation and them move on to more difficult tasks once the child becomes more comfortable

Q

What is a good protocol for CPA?

A

A good protocol is to start at 2,000 Hz in one ear and then move to 2,000 Hz in the other ear
Then repeat at 500 Hz

23
Q

How do you determine a starting level for testing CPA?

A

Case history and interaction with the child will give you some information regarding the level at which the child should be hearing sounds

24
Q

What level should you train the child?

A

Train the child at a level they hear
If a child responds at normal conversation levels, then we can probably start training around 40 to 50 dB
If the child does not respond a normal conversation levels but seems to be developing otherwise in a normal manner (e.g. Motor skills) the child may have a hearing loss, then start your training at a high intensity level

25
Is it better to have one person in the room and one running the test?
Yes, but it can be done with only one person
26
Do we have to teach the child to respond at the onset of the auditory stimulus?
Yes
27
Is a period of pre-play beneficial?
Yes It helps comfort them in the new environment and puts them at ease with unfamiliar faces You can also see what toy the child is naturally drawn to
28
What is an example of a behavioral response (targeted response)?
The child holds a toy up to his ear and drops it in a bucket when he hears a sound
29
What is the conditioning process?
Auditory stimulus Behavioral response Reinforcement
30
Should you be careful to suggest activities that need good dexterity?
Yes
31
What is a response defined as for conventional and play audiometry?
Performance of the desired motor behavior within 3 seconds of the stimulus onset No later than 4 seconds
32
What is a false responder?
Responding when they don't hear anything
33
How do you manage a false responder?
The audiologist can place an open hand just in front of or resting against the child’s hand holding the response peg or block. The child then has to go around or through the audiologist’s hand to complete the task once the sound is heard
34
What is a reluctant responder?
These children frequently wait until they are visually prompted to complete the task despite numerous training trials and reinforcement
35
How do you manage a reluctant responder?
The audiologist might want to identify if there is a definite facial response or reaction when the tone is presented and can then assist the child in completing the play task and watch for the child’s reaction to the next stimulus
36
What is an off responder?
These children prefer to wait until the stimulus has stopped prior to completing the task
37
How do you manage an off responder?
Using a continuous tone can often assist them in feeling more confident in responding because there is a definite “off” to the signal
38
How do you train a child for CPA?
The assistant shows the task (hold toy near ear, "I hear that", drops toy in bucket) Assists the child (holds child's hand with the toy next to the child's ear, "we hear that", moves the child's hand and directs them to drop it in the bucket Child attempts on their own
39
What can you do if the child is hesitant to do it themselves?
Encourage the parents to try Guide them by saying "you heard it, you can put it in"
40
What happens after several training trials?
Probe trials are done to determine if conditioning has been establishedIf successful, move to phase 2 (threshold exploration) If unsuccessful, increase intensity level and present additional conditioning trials If still unsuccessful, consider other important factors (physical, cognitive, social) and use VRA
41
What are some common forms of positive reinforcement?
Verbal praise - “that’s good”; “good listening” Social reinforcement - pat-on-the-back; a smile and nod of the head; applause Tokens that can be traded for small toys or stickers at the end of the test session, unsweetened cereal, or a changing computer display screen
42
Should you start with 100% reinforcement?
Yes Then gradually shift to an intermittent reinforcement schedule When in doubt, don't reinforce (reinforcing a false response can confuse the child)
43
What should you do if you're uncertain that the child has heard the sound even at loud levels?
Try conditioning with the bone oscillator They will feel the stimulation and then learn the task from that Resume with air conduction after
44
Will a variety of interesting toys increase the probability of keeping the child's attention?
Yes
45
What are some activities used in CPA?
Toss a ball in a basket when the sound is heard Place a puzzle piece in the puzzle when the sound is heard Put a ring on the cone when the sound is hear Place a peg in the pegboard when the sound is heard Give mom/dad a high-five when the sound his heard Place a block on the castle when the sound is heard
46
Do children with mild to moderate hearing loss require special test adaptation?
No
47
What is the test adaption that might be needed with severe to profound hearing loss?
The probe from the insert earphones can be attached directly to their personal earmolds If the child does not respond at the audiometric limits, it may be possible to obtain a response using a bone vibrator held either in the child’s hand, on the knee, or on the mastoid Once the child responds consistently to the tactile stimulus, begin testing with earphones at 250 or 500 Hz
48
When does bone conduction need to be performed?
Concern about conductive component Hearing loss
49
What is the challenge when testing young children with bone conduction?
Placing the transducer Two or three thresholds may be sufficient if attention is an issue Conductive HL :250, 500 and 2000 Hz are more critical to obtain Sensorineural HL: 500, 2000 and 4000 Hz are more critical to obtain
50
What is computer assisted testing?
Child has a mouse Adds features to a screen (hat added to a clown) The child clicks the mouse Audiologist controls the mouse from the control room
51
What should you do if you have a difficult child?
Don't offer options that are not really options ("do you want to put the headphones on?") Do not try switching to different testing technique (immediately) Try short breaks, new toys, new assistant, parent as assistant, new stimulus, bribery Allow the child to sit on parent's lap Give some indication of how long the test will be
52
What are some benefits of using CPA?
Accurate responses possible at threshold level Can be conducted in soundfield or with earphones, with bone oscillator, hearing aids, or cochlear implants
53
What are some challenges of CPA?
Keeping the child entertained and involved long enough to obtain all the necessary information
54
When can conventional audiometry be used on children?
When they are older than 5 The child raises a hand or presses a button in response to the auditory stimuli rather than completing a play task
