Learner Outcomes
Examine research on auditory brain development and how this impacts auditory learning of children with hearing loss.
Identify and sequence specific auditory behaviors that occur in the development of spoken language and will identify components of a detailed model of auditory learning.
Apply information about specific formant frequencies of individual phonemes to the auditory learning of spoken language.
Identify factors that affect the auditory reception of spoken language and select appropriate strategies and techniques for assisting auditory perception of particular features of spoken language.
Predict levels of development in speech, language, cognition and communication in relation to level of auditory development.
Develop A-V lesson plans including goals, activities, strategies and carry-over ideas for specific cases.
Auditory Brain Development & Auditory Processing
We know what you are thinking….What a fun, exciting, interesting, motivating, attention-grabbing, fascinating way…. to start the day!!!
The goal for children in an AV approach is spoken language.
The MOST effective modality for acquiring/teaching spoken language is HEARING.
What do we know about the relationship between listening, literacy and success in reading?
Auditory Brain Development
It’s all about the BRAIN!The ears are just the way in…
Quick Quiz…We’ll answer these & other REALLY important questions
Measurable differences in brain organization and neural activity is caused by ______ ______.
Research by Sharma indicates that the brain waves of children who begin wearing hearing aids or cochlear implants by _____ years of age reflect a normal response to sound.
What is developmental synchrony?
Is there a critical period for the development of auditory function?
A-V Principles 1 & 2 Newborn hearing screening
programs & 21st Century technology allow access to the auditory centers of the brain
Access is a good thing!In fact, it is great!Is it enough?
Easy Math…
Early identification + early & appropriate technology + appropriate intervention by parents & professionals during the period of maximum neural plasticity = potential for achieving high levels of speech, language, reading, literacy & success in school.
Neuroplasticity----Current Research
The infant brain has neural plasticity.
Complete maturation of the central auditory pathways is required for the normal development of spoken language in children.
The period of greatest neuroplasticity is the first 3 ½ years of life (Sharma et al, 2002; 2004; Sharma, Dorman, and Kral, 2005).
Children implanted by 12 months of age may demonstrate more benefit than children receiving implants later on in the period of maximum neural plasticity (Sharma, Dorman, and Kral, 2005).
When children acquire skills at or near the time that they are intended to do so biologically, this is called developmental synchrony.
Making the Connections…
A baby’s brain continues growing beyond the womb—not just in size, but in forming connections
Born with 100 billion neurons. By 3 years of age babies have about 15,000 synapses per neuron, three times the synapses of adults. What happens to synapses that are not
accessed?
Making the Connections…
“Babies are citizens of the world.” Neurons in the auditory cortex
Laborers with no job assignments As the infant is exposed to spoken language,
different clusters of neurons in the auditory cortex are recruited to respond to different phonemes
Neuron clusters fire only when a nerve from the ear carries a particular sound
By 12 months of age a child’s “auditory map” is established
Making the Connections…Training OR Learning?
For the young child,meaningful contexts are crucial for the auditory processing of spoken language. “The hearing-impaired child’s auditory
abilities develop ‘because emphasis is placed on listening throughout all waking hours so that hearing becomes an integral part of his/her personality.”
(Pollack, 1985)
It’s All About Experience
Experience & Vocabulary Vocabulary size correlated with quantity of
maternal “talk” 20 months of age—offspring of talkative
mothers averaged 131 more words than children of less talkative moms
At age two, the gap doubles Critical factor—number of times the child
HEARS different words TV doesn’t produce same results. Why not? Information within context seems to stimulate
neural circuitry
What happens when the auditory centers of the brain are not accessed early?
Decreased ability to use sound meaningfully (cross-modal reorganization)
Physiological changes Psychosocial factors When the hearing aids are OFF what
happens?
Auditory Processing of Spoken Language “The auditory processing ‘whole’ is
greater than the sum of current knowledge of its hypothesized parts.”
(Cole,1992, 2006)
Components of auditory processing models
Peripheral hearing structures are responsible for analysis and conversion of speech/acoustic information to nerve impulses for transmission to the brain Brief memory storage required
Preliminary processing in the brainstem Localization and selective attention
Auditory cortex receives input Higher level analysis includes: phonetic,
phonological, syntactic, semantic, and pragmatic/contextual processing
Take Home Points…
We hear with the ____. Neuroplasticity is greatest during the
first ___years What is the purpose of hearing aids and
cochlear implants? What happens when the auditory
centers are not stimulated early? Full maturation of the central auditory
pathways is a must for________.

Let’s Talk about Hearing Age
Relationship between age at first amplification and a child’s chronological age
Calculated from the day the child begins wearing amplification
Hearing age is the term used to put progress in perspective
Listening experience Mixed hearing history
Other Terms
Cochlear Implant Age = length of time since CI “hook-up.”
A-V Age = length of time enrolled in Auditory-Verbal Therapy
Language Age = level of understanding and use of language
Application
John is an 11 month old boy whose moderately severe bilateral hearing loss was diagnosed at two months of age. He began wearing hearing aids at 3 months of age and began AVT at the age of 5 months.
What is John’s hearing age? What is
his program (AVT) age?
At a chronological age of 3 years 8 months, John obtained the following scores on standardized measures of language:
PLS-4 AC 101 AE 98 Total Lang. 100 A.E. 3 years, 7 months
Peabody Picture Vocabulary Test-III SS 92 A.E. 3 years, 3 months
Discuss the test results for John in relation to: Chronological Age Hearing Age Program Age
Application
Cate is 4 years, 6 months of age. Her severe-profound bilateral hearing loss was identified at 13 months of age, and she was subsequently fitted with hearing aids at 15 months. What is her hearing age?
Cate received a cochlear implant at 2 years, 6 months and began AVT at the same time. Note: Cate was enrolled in a TC program from
16 –28 months of age. What is Cate’s CI age? AVT age?
At 4 years, 6 months of age, Cate has an expressive vocabulary of 284 words. She consistently uses 3-word combinations spontaneously such as “I want cookie” “no want that” and “I do it.” She can recall 3 critical elements, identify objects when given related descriptors and can identify segments of sequence stories. She demonstrates accurate vowel production and uses /p/, /m/, /w/, /h/ correctly in spontaneous speech. Cate uses all suprasegmental features of speech appropriately.
Discuss Cate’s present level of functioning in relation to her:
Chronological Age CI and AVT Age

Semi-Formal Teaching
Formal Teaching
•Happens in normal, everyday events and interactions•Should occur at home and school•All learner types
•Seize the moment•Use of strategies to embellish the normal situation•Should occur at home and school•All learner types
•Adult directed, pre-planned activities•Developmentally appropriate•Specific goals and objectives•Use of strategies•Typically done at school•Delayed & remedial learners
•Adult directed•Deliberate, direct, methodical•Specific goals and objectives•Use of strategies•Happens in traditional educational setting•School age remedial learners
Types of Learners

Six-Step Guide To The Development of an Auditory Function in an A-V Approach
With the parent: Evaluate the child’s present level of auditory
development within the context of a detailed model for normal auditory development
Determine next appropriate target Compare acoustic characteristics of the
target with child’s auditory potential (audiological information)
Select sense modality (consider hearing 1st) Develop the target through informal learning-
formal teaching Evaluate progress toward goal often
Lesson Plan Development: Point to Ponder
Hearing children learn language through listening as they seek to extract meaning from their environment (Ling, 1986) What, in the child’s mind, is the reason
to listen during this activity?
Lesson Plan Development:Point to Ponder
What is your major focus? Helping the parent to integrate new
strategies into established daily routines?
Helping the parent integrate new activities that promote listening into his schedule?
Both? Neither?
Lesson Plan Development:Point to Ponder
Hearing children develop auditory behaviors in conjunction with speech, language and cognitive goals Integrate goals within one activity rather
than teaching each area in an isolated activity
Develop auditory behaviors in coordination with “hearing age” rather than chronological age until the gap is closed

Daily Performance
Ongoing diagnostic teaching
The AVT must be able to assess why a child is having considerable difficulty with particular goals and drop back to lower steps on the hierarchy.
When a child is demonstrating competency with particular goals/skills, the AVT must be able to move on to new areas (goals/skills that can be accomplished with support).
AVT must know prerequisite skills as well as those 1-2 levels above the selected target.
