Educational Challenges for a child with a hearing loss
• Vocabulary Development• Communication options• Development of reading skills• Behavior
– frustration
• Social
Brown’s Stages of Expressive Language
• Stage One- 15-30 months– About 50-60 word vocabulary
• Stage Two - 28-36 months– Add Present progressive verb endings (-ing)– Add usage of in and on– Begin to use plurals
• Stage Three- 36-42 months– Add irregular past tense (me fell down)– Possessives– Use of TO BE verbs
Brown’s Stages of Expressive Language
• Stage Four- 40-46 months– Add use of articles– Regular Past Tense (she jumped)– -ed endings– Third person regular tense (he swims, man brings)
• Stage Five - 42-52+ months• Third person irregular (she has, he does)• Full form of TO BE verbs ( Are they swimming)• Shortened form of TO BE verbs when only verbs in the sentence.
( She’s ready)• Auxilary form of TO BE ( They’re coming.)
Stages for Deaf Children and Children with Autism
• Children with autism MAY begin to move through the language stages and then stop upon entering Stage Two or Three
• Deaf children of hearing parents are delayed in all stages of their development. They will continue to use gestures until explicit exposure to language through either auditory or visual channels. This may not occur until a child enters school at the age of three.
Language Development
• Hearing Loss– Lack of expressive
language development– Responsive to adult
interactions– Participates in turn taking– Acquires, but has difficulty
with JOINT ATTENTION– Natural pattern of ASL
grammar and syntax even in deaf of hearing parents
– Low Base Vocabulary
• Autism– Loss of Language at
about 18-24 months– Unresponsive to adult
contact– Does not participate in
turn taking games– Lack of JOINT
ATTENTION– Echolalic– Reversal of Pronouns– Lack of Pragmatic

Number of children with autism Number of children with autism in Illinois is increasingin Illinois is increasing
Number of children with autism “counted” in Illinois has more than doubled over the last five years.
Number of children with hearing loss stays steady
Variation in diagnosis/identification
Why is ASD increasing?
Greater awareness
True increase
ASD prevalence affects approximately an average of 1
child in every 150

prevalence for hearing children)

Hearing loss occurs more often in children who have autism
than in children without autism
Rosenhall et al., 1999
When are children with ASD When are children with ASD diagnosed?diagnosed?
Average age of hearing child diagnosed with autism 3.1 years old
Average age of deaf child diagnosed with autism – 4.1 years old

How are children with ASD How are children with ASD diagnosed?diagnosed?
• General and Developmental Milestones
• Routine Developmental Screening at well child visits– Refer to Early Intervention– Lead screening– Formal Audiological Assessment– Autism Screening– Formal Diagnostic Evaluation

Early Diagnosis and InterventionEarly Diagnosis and InterventionVery Important!
Jacobsent, 1998/Columbia Pacific 1999
Inhibits development of inappropriate behavior
Teaches functional communication
Promotes healthy family adjustment
Early Diagnosis and InterventionEarly Diagnosis and Intervention
Children with ASD or Hearing Loss who begin intervention before the age of 3 achieve more positive outcomes than those who begin intervention after age 3.
Very Important!
Jacobsent, 1998/Columbia Pacific 1999
•Later diagnosis makes critical early intervention less achievable
• Hearing loss can mask autism Szymanski and Brice, Odyssey Magazine, 2008
Diagnosis and Intervention
Communication Issues
• Communication that is Transient– message there
then gone– easily missed
• sign• speech
• Develop communication processes that are Non-Transient– Message there long
enough to take in and process
• printed• objects
Language Development Practices that can aid both
Deaf Children and Children with Autism
• Repeat signs/speech and short sentences again and again. This gives the child several chances to notice them and recognize the language patterns. Babies seem to find repeated language interesting. Tap on objects, point, use interesting facial expressions, and use other strategies to help babies/children see and pay attention to language.
Nonverbal children can benefit:
• One strategy deaf mothers use often — waiting for a child to look up before signing to them — means that deaf mothers tend to send fewer language messages to their babies than hearing mothers do in the same amount of time. Still, the signed language skills of deaf babies with deaf signing parents develop as quickly as the spoken language of hearing children.
Sign Language Development
• Children with autism avoid eye contact• May be helpful for children with Autism due
to difficulties with cross-modality – converting auditory information to vocal utterances (Bonvillian et al., 1981) or severe auditory processing deficits (Ruttenberg & Gordon, 1967)
Communication Support
• Wait• Use visual tools
– schedules– calendars– visual directions– Children who have started in a HI program
and then placed in programs designed for children with autism move through a PEC system quickly. ?Why?
Social Differences
• Lack of interest in relating to others• Don’t understand facial/vocal/body cues• Joint attention- feel as if they are not
attending to you. Can’t share the moment. This is especially difficult for deaf children with Autism as they can’t attend to the object without missing the signs.
• Reciprocity• Social praise not effective as a reinforcer• Social Stories a useful tool
Behavior Differences
• Restrictive repertoire
• Prefer Routines
• Strong impulses
• Sensory issues lead to ‘melt downs’
• OCD/Perseveration
Behavior
• Problems frequently due to communication
• Difficulty with– beginning or ending activities– transitions– change
Behavior Support
• Visual tools-visual timers
• Routines/schedules
• Limit input
• Provide social training
• Direct teaching of social skills
• Adapt the environment
Deafness and Autism
• Study by Jure, Rapin, and Tuchman (New York)– 46 subjects investigated– 11 had undiagnosed autism for over four years after
the diagnosis of a hearing loss.– 10 children with autism had unrecognized hearing loss
for several years after diagnosis of autism.– Educational experience was ‘generally disastrous’
because of the late and incorrect diagnosis, and lack of specialized facilities for HI children with Autism.
Deafness and Autism
• Children with Autism may have undiagnosed hearing loss.
Taylor, Rosenblatt and Linschoten
• Studied 32 children with autism. ABR studies showed that 11 had undiagnosed moderate hearing loss, 3 had a severe to profound hearing loss.
Syndromes that Mimic a PDD
• Angelman Syndrome
• Landau-Kleffner
• Williams Syndrome
Parting Thoughts
• How can we limit social isolation?
• Placement issues
• Parental acceptance
• Behavioral “blame” - Which comes first, the deafness or the autism?
