Changing Outcomes
Aleisha DAVIS, Anne FULCHER, Alyshia HANSEN, Katie NEAL
AGBell LSLS Symposium
10th July , 2015
Baltimore, Maryland
• 45 years of service to >2000
children
• Focus on Listening and Spoken
Language
• Family-centred Transdisciplinary
• Integrated Implant and Early
Intervention Program
• Families from diverse cultural and
linguistic background
• Individual, Group and
Teleintervention Programs
• 5 Centres with services across ACT
NSW Tasmania
• Children with all range of needs,
all levels and types of hearing, all
devices options
• Currently 250 children 0-6yrs,
135 children 7yrs plus
Before speech and language, comes
“Although children make use of visual cues when learning language,
audition is of primary importance for language acquisition”
Bailey & Snowling, (2002), Yoshinaga-Itano, C. (1998) Geers, A., Brenner, C., & Davidson, L. (2003).
Children’s outcomes measured by
Vocabulary
Social Skills
Pragmatics
Language
Speech
Literacy
Listening
How can we identify progress before it
shows in speech and language outcomes?
Track development of the prerequisite skills on
which speech, language and communication
are built
The importance of audition
“Although children make use of visual cues when
learning language,
audition is of primary importance for language
acquisition”
Bailey & Snowling, (2002), Yoshinaga-Itano, C. (1998) Geers, A., Brenner, C., & Davidson, L.
(2003).
Quantifying what infants can hear
• UNHS (AABR)
• Diagnostic ABR
(hearing level and basis of device fitting)
• Hearing aid fitting
• Verifying & optimising access to sound
(behavioural/subjective measures)
• Maximising opportunity
(early diagnosis, early fitting, early intervention)

However,
What do we know about their real
world/functional listening skills?
Example study: The importance of
functional listening
CAEP & Ling Sounds:
Implications of Matches and Mismatches
Cortical Auditory Evoked Potentials
(CAEP’S)
• Evoked potentials = small electrical signals produced
by hearing pathways in the brain.
• Response is measured from the brain.
(NAL Hearlab information sheet, http://hearlab.nal.gov.au/pdf/CAEP%20parent%20handout.pdf)
• HEARLab® system designed to make objective
audiological assessment easy and efficient.
• Includes in-built statistical procedures to determine present or absent
response, allowing by non-expert electrophysiologists
• Researched & developed through NAL & CRC (Aust)
• Provides Objective verification of hearing aid fitting
Detection Response at level of the cortex
Functional Listening
• Real world listening skills
• Provides an indication of what a child can do with a sound
(in addition to what they may be able to detect)
• Trained professionals that see infants on a regular basis have a
very good understanding of what functional listening skills each
child has
• The core of a specialized early intervention auditory focused
program
– From the earliest point (skills begin to show from a few weeks of
–
–
–
–
age)
Pre-requisite for speech and language
Picture built over a period of time
Involves combination of measures – no one test stands alone
Every child is different, so individual focus impacting factors to
functional listening development
How to measure functional listening?
Variety of current tools
• Functional Listening Index (tracking auditory devt skills from 0 – 6years)
• Categories of Auditory Performance – Revised
• Ling sounds/ Seven Sounds (ah, oo, ee, mm, sh, s, or)
• Auditory Skills Checklist
• St Gabriel’s Curriculum
• Integrated Scales of Development (Cochlear Ltd))
Amongst others…
In quiet and
noise
Close and from
a distance
Individual and
separate ears
Live and digital

Match or mismatch?
•
•
41% (n=23) match with cortical responses and behavioural responses to phonemes.
59% (n=33) mismatch with cortical responses and behavioural responses to phonemes.
• 19/33 (58%) had all cortical responses present but
a mismatch with functional listening.
What happens next?
Match or mismatch?
• 3/33 hearing aid optimization lead to
matched results
• 21/33 have gone on to have at least 1 CI
• 4/33 CI evaluation
• 3/33 transferred to other programs
• 1/33 significant additional needs
• 1/33 with ongoing middle ear
What does CAEP testing mean for
families?
• 18 recalled having the testing and could recall the results
• 4 families had a good understanding of the purpose
“to get brain response to see if getting any benefit from the
aids”
• 5 families had a poor understanding of the purpose
“confirmation of diagnosis” , “to see if the inner ear is
functioning & the hearing levels”
• 6 understood implications
• 3 had limited/poor understanding
“it’s really confusing, this is saying he can hear everything”
Impact of interpretation
“confirmed what I had been seeing and what I was feeling”
“at the time, we had passed the emotional part and into acceptance “
“always had hope never minded do another test”
“Overall – 100% beneficial sitting down and reviewing results much needed
and necessary for me to hear and understand”
“For me yes, for my husband not so much, he was in denial wanting
something 100% concrete”
“Yes a more technical result”
“ “Yes but also confusing”
“when we got a positive result, it gave us hope that with time maybe the
hearing would get better”
” Hard to take. Felt like getting the news of a HL all over again”
“Very nervous, much more meaning attached”
“struggling said can hear but not seeing this. Made us doubt everything”
Impact of match on
listening development
Match =
Starting and staying on the same
listening trajectory
Match =
Initially poor trajectory
Rapid change with improved access
Impact of mismatch on
listening development
Mismatch =
Poorer than
expected

Mismatch =

Comprehension

Detection
Building communication
• A present cortical response indicates detection of something at
the cortex
• An absent cortical response may be present but not measureable
• There is no 100% correlate between a speech signal and the CAEP
stimulus
• It’s beneficial to take time with families to clearly and simply
explain what additional information CAEPs might provide. This
needs flexible delivery of services and information (written and
verbal)
• To fully understand hearing, consider all of the available evidence
in the context of the whole child
• Anything that add to the picture of understanding what a child
might be hearing is useful
Given the importance of functional
listening on outcomes
How do we best track listening skills over time to
tell us about later speech and language progress
and development?
One day a number of creatures sat in the
forest and pondered the important questions
in life…
‘what tools do we use to measure
listening skills?’
The creatures were sure that many others
had pondered the same question.
From their experience,
Listening and Spoken Language Therapists, Specialists
and Teachers of the Deaf …
1.
used different tools according to individual preference
2. were looking for different tools
3. were having difficulty comparing children’s progress
4. Didn’t have detailed normative data
5. Often asked to measure auditory skill in terms of speech perception abilities
which didn’t involve comprehension element
Wanted a tool that :
6. Could track a child’s listening progress over time
7. Had more detail & smaller steps
8. early to advanced listening skills
9. more advanced listening skills (with early diagnosis, early fitting, early CI)
10. Able to recorded individual skills in progress notes from every session
11. found overlap between auditory and receptive language skills
The problem with tracking listening
skills over time
•
•
•
•
•
•
•
•
Number of different tools
Differing knowledge of what tools exist
A tool that is able to track listening progress over time (0-6yrs)
Able to compare a child’s progress
Has detailed normative data
Has scales with detailed steps
Has early to advanced listening skills
Able to record individual skills in progress notes

• Evaluation- beyond traditional measures
• Programming: objective/automated measures
• Therapy- direct audio input? Integrating signals? Overall
family/individual goals
Outcomes =
Variability. 3 excellent performed.
Improved attention
Speech awareness, speech at word level better than pre CI
Awareness of sound
Ability to focus and listen to softer sounds has improved
Listening in background noise (less repetitions, can hold more
UHL & Cochlear Implantation
• Typically younger = quicker integration
• Assisting families deal with the preconceptions of
others
• Investigation of aetiology (MRI, genetic testing)
• Funding issues still exist, Importance of counselling
GOALS: Good full-time device use, measurable improvement in access to
sound, observed change in listening ease and confidence
