Part
1: Overview of Prelinguistic development
• Why focus on stages of prelinguistic development?
• Typical and atypical developments
Part
2: Assessment Strategies
Part 3: Interventions
• Specific considerations for Down syndrome and FXS
Part
4: Working with communication partners
Gestures
and vocalizations that precede speech
in typically developing children
Occur in a developmental order
Why
focus on describing, assessing and
teaching these types of behaviors?
There
is great variability in the communication
skills of prelinguistic children
Prelinguistic = before children are speaking or
signing or using another formal language
system
“Perlocutionary”
= children communicate by
crying or acting on objects. Others assign
meaning to these behaviors.
Next
sections:
• Vocalizations
• Coordinated attention
• Gestures
Crying
and experimental sounds
and experimental sounds continued –
“Raspberries”
Crying
Canonical
babbling (reduplicated consonant
vowel babbling)
Variegated
babbling (jargon babble)

Crying
Experimental
Sounds
(e.g., raspberries, noncanonical babbling)
Canonical Babbling
Variegated Babbling
Speech
Do
we hear similar vocalizations in older
children and adults with disabilities?
Should we continue to encourage vocal
development in older children and adults with
disabilities?

Anatomical
differences
• Vocal folds
• High palatal vault
• Larger than typical tongue in relation to the oral cavity
• Weak facial muscles
• General hypotonicity
Is
babbling delayed in DS?
• Not much!
Recent
study by Thiemann-Bourque, Warren
and Brady:
How do children with Down syndrome differ
from an age and SES matched sample of
typically-developing children in regards to
their home language environments (i.e., adult
words, child vocalizations, and adult-child
conversational turns)?
Differences
in prelinguistic quality and
quantity of vocalizations in children with
Down syndrome
Discriminative
vocal characteristics could be
used to help identify children at risk for ASD
Automated vocal analysis of naturalistic
recordings from children with autism, language
delay, and typical development
Oller, Niyogic, Grayd, Richards, Gilkerson,
Xud, Yapaneld, and Warren (2-10)
Lots
of variability
Aka…joint
visual attention, line of visual
regard,
What is it and why is it important?
Within
routine, child is looking at object, then,
intersect gaze
Verbally
prompt for eye gaze
Specifically acknowledge the eye gaze
Provide the desired object contingent on the
eye gaze
Bring
toys up to face
Step 1. obtain the child’s attention (e.g., move face in
front or call their name)
Step 2. Look in direction of a “target even” (e.g., remote
control car or fan)
Step 3. Activate the target event
-repeat Steps 1-3 many times Step 4. Gradually increase the time interval between the
shift in the gaze and activation of the event. (This
creates opportunities for the child to anticipate and look
in direction that interventionist is looking)
Activity: practice teaching eye gaze shift with a friend
Illocutionary
or purposeful gestures
What is the function?
• Behavior regulation = imperative
• Joint attention = declarative
• Social interaction
Crais
et al. (2004) study
• Deictic vs. representaitonal
• Different functions
• What’s the developmental sequence?
Contact
gestures = gives, leading by the hand,
showing. Gestures that are in direct contact
with an object or person.
Example
of a contact gesture
Distal
gestures = points. The index finger is
extended and other fingers are pulled back. The
gesturer is not in direct contact with the
referent.
Example
of a distal gesture
Head
nod and shake, shoulder shrug, open
palm request
Depictive gestures such as pantomimes
Sometimes
people combine gestures to convey
complex meanings
• Gesture + vocal combinations
• Gesture + gesture combinations
• Gesture + word combinations
Examples
gestures
of children combining 2 or more
Work
in pairs or groups
One person act out the title of the song from
the paper
Partner guesses the title
Discuss the types of gestures you used to
convey the title
What titles seemed easier and why?
Other
child behaviors correlate with these
stages
Intervention strategies may differ for children
at various stages
Stages are like “milestones” that indicate to
parents and teachers that children are
progressing
Form
and function
• Individuals with intellectual disabilities who only
communicate with contact gestures rarely communicate
“joint attention” (comments).
Lack
of joint attention- example of boy with
autism
Persons
who communicate with contact
gestures and distal points frequently
communicate joint attention
Significant differences between contact and
distal gesture users reported in:
• Brady, Marquis, Fleming & McLean, 2005; Brady,
McLean, McLean & Johnston, 1995; McLean, Brady,
McLean and Behrens, 1999; McLean, McLean, Brady
& Etter, 1991)
Example
task.
of person pointing in a joint attention
Individuals
who communicate with only
contact gestures communicate significantly less
often than children who communicate with
more advanced gestures
Findings reported in Brady et al.,2008; Brady
et al., 2001; 2004; McLean et al., 1999)
Example
of low rate communicator
Example
of high rate communicator
Children
who use only contact gestures try to
repair communication breakdown less often
than children who use more advanced gestures
Input
How
do children respond to gestures?
• Respond to joint attention
• Disambiguate messages
Brooks
and Meltzoff, 2008 JCL
• Gaze following, as measured by length of looking at
object adult looked at, significantly predicted
vocabulary
• 11 month olds who pointed had an additional 1.16
words/month…or 167 word advantage by age 2
Differences
in gesture type associated with
differences in:
• Communication functions (requests, comments)
• Frequency of communication
• Repairs of communication breakdowns
Are
different intervention strategies better for
children at different stages of prelinguistic
development?
Examples
• Teaching children to use natural gestures
• Outcomes from teaching words or other symbols to
individuals at different stages of communication
development
Individuals
progress in communication even if
they have not yet begun using words or
symbols
Progress in:
• Frequency of prelinguistic communication
• Use of points and other advanced gestures
• Diversity of communication functions
• Repairs of communication breakdowns
Assessment
strategies for prelinguistic
individuals
Intervention strategies for prelinguistic
individuals
• Increasing parent and peer responsivity
• Teaching joint attention
Standardized
assessments are not very helpful
Need to determine how a child is
communicating across environments
Early
identification of a language problem
Early identification of a developmental
disorder
Predictive value for later language
Provides information for identifying
intervention goals, monitoring progress
Responsiveness to prelinguistic behaviors
provides linguistic input
Parent/Caregiver
Questionnaires
Direct Observation
Assessment Protocols
Characteristics
of a good parent questionnaire
• Questions about here and now
• Use recognition memory (vs recall)
• “What does your child do when he or she needs help
(e.g., opening a container or getting a toy to work)?”
How
to use information from parent
questionnaire
Examples
of Questionnaires
• What do you use?
Good
contexts to observe in
• Contexts indicated by the questionnaire as showing
high probability of communication
• Meal or snack time
• Contexts for vocalizations?
1.
list student characteristics-age, setting, likes,
dislikes, sensory abilities
2. list two or three good activities/contexts to
observe and why
3. Describe what communication behaviors to
record and how.
How could you summarize your observation?
Tests
designed to see if the individual will
communicate with whatever means available in
order to request, comment, etc.
• If no communication noted in Direct Observation, need
to see if they will do it when provided a specific
opportunity to do so
Adaptations
for older participants
Assessment
protocols have been used in
research by Dr. Brady and colleagues to study
Initiations
• Requests and Comments
Responses
to Communication Breakdowns
Example
of child initiation
Example
of repair protocol item
Case
1, boy with fragile X syndrome
• Assess two things-rejecting (or protesting) and repair
Case
2, girl with Down syndrome
• Assess indicating preference of different items
Case
3, boy with autism:
• Assess use of PECS and gestures to indicate joint
attention (commenting) functions)
Case
4, individual your group previously
“created”
The
Communication Complexity Scale = CCS

How
would you score the following example:
Example for a boy that uses lots of different
forms!!
Average
of the three highest forms observed
Can average within each function (joint
attention; behavior regulation)
Assessments
are designed to determine how
and why a prelinguistic child communicates
Gather information from interviews, direct
observation, and assessment protocols
Assessment protocols can be constructed to
provide opportunities for particular behaviors
of interest
• Repairs, communication with peers, use of AAC
Summarize
information regarding:
• Communication forms
• Functions
• Frequency/rate of communication
• Stage of prelinguistic development
• Initiations/responses/repairs
• Contexts
• Motivation
Increasing
prelinguistic communication
• Gestures
• Vocalizations
• Eye gaze
Increasing
communication across multiple
contexts and with multiple people
Facilitating transition into symbolic
communication
• Speech, sign language, pictures
Create
contexts where children communicate
naturally
Follow the child’s lead but address specific
communicative targets
Use the least intrusive prompts necessary to
promote communication targets
Increase
the frequency and complexity of
requests and comments
For both of these goals the first step is to build
routines
Theoretical
reasons
• Occur developmentally
before symbolic
communication
• Thought to pave the way
for symbolic
communication
• Provide opportunities for
linguistic input
Practical
reasons
• May be easier to teach
than some forms of
symbolic communication
• No extra equipment
needed
• Gestures are readily
understood by members
of community
• Can be used across many
different contexts
Gestures
as one part of communication
intervention
• Early phase of expressive communication
• As augmentative forms when other forms of
communication are not available or are not working
e.g., SGD not available
e.g., communication partner doesn’t know sign
Principles
described in Prelinguistic Milieu
Teaching (PMT), see Warren et al., (2006)
• Warren, S., Bredin-Oja, S., Fairchild Escalante, M.,
Finestack, L., Fey, M., & Brady, N. (2006).
Responsivity education/ Prelinguistic milieu teaching.
In R. McCauley & M. Fey (Eds.), Treatment of
language disorders in children (pp. 47-77). Baltimore,
MD: Brookes Publishing Co.
Step
1: Find objects/activities/people that
participant will be motivated to communicate
about
• Different for every individual
• Preference assessments or questionnaires
• Examples of activities: toy box, snack activities, motor
activities like swinging,
• Range to match development and interests
Step
2. Develop turn taking routine(s)
involving activities identified in step 1
• Examples:
Rolling a ball
Putting colored discs on a light box
Pretend cutting food
Turning on and playing with any battery operated toy
• More elaborate routines can be used with children who
have advanced play skills
Meal
times
Getting ready to go outside
Play with a certain toy or object
Songs with repetitive lines and actions
The type of routines will vary with the child’s
play skills
Step
3 (for teaching requests)
• Interrupt the routine in order to provide an opportunity
for the child to request
• For example: hold on to the ball, or pause the swing, or
turn off the battery operated toy….
• May add an expectant look
Step
4: wait
Step 5: if necessary prompt the targeted response
• Physical, hand over hand prompts
• Model prompts
• Verbal prompts
• Fade prompts as quickly as possible

Step
6: continue the routine/activity. This
reinforces the child’s behavior.
General
pointers
• Shorter routines provide more opportunities for
communication
• Change activities when child just begins to lose interest
One
of you is teacher, other is student
Using the steps we just discussed….Teach
student to do one of the following:
• Point to blinking fan
• Open palm request for yummy treat
• Give to request more bubbles
• Vocalize to continue a social routine
Reverse
roles
Vocal
play
Imitation
use
sounds within child’s repertoire
Verbally
prompt for vocalizations
Specifically acknowledge vocalizations
Vocalization + eye gaze + gesture
=
a clear, recognizable communication act!
Time
Delay
• If the child produces one or two components of a
communication act, wait expectantly (i.e., use time
delay) to prompt the second (or third) component.
Ask,
“what do you want?” or another general
prompt and wait again
Immediately
after the child produces the
targeted component (eye gaze, vocalization or
gesture), provide the appropriate consequence
and verbal feedback
Children
with Down syndrome
Children with autism
Children with fragile X syndrome
Children with multiple disabilities
Children learning AAC
Characteristics
to consider when planning
assessments and interventions
• Intelligibility
• Learning style (may not respond well to “Do/say ___.”)
• Persistence
Exciting
new treatments in development!
• http://garnerlab.stanford.edu/DS_Research.html
Fragile
X syndrome (FXS) is the leading
inherited cause of mental retardation
Delayed language typical in boys
Profiles: relatively weak in
• Short term memory
• Processing sequential information
• Directing and sustaining attention
Co-occurrence
of ASD in about 10-40% boys
Characteristics
to consider when planning
assessments and interventions
• Wide range of variability of communication
• Many autistic-like characteristics
• Mothers may be shy or reticent in their interactions
• Oral needs
Exciting
new developments
• Drug trials
• Newborn screening
Input
includes sign and touch cues
Directionality of communication act, indicated
through whole body orientation (not just eye
gaze)
Routines emphasize tactile and vestibular
stimuli
Prompts are physical rather than verbal
Research
isn’t available yet to guide this
decision
We start working on words when children are
communicating prelinguistically at a rate of
more than one communication per minute
Start sooner with children who have severe
physical impairments
How
can AAC complement prelinguistic
interventions?
How can prelinguistic interventions
complement AAC?
AAC
does not slow down acquisition of speech
communication
• Blishak (2000); DiCarlo et al. (2001); Kouri (1988);
Shepis et al. (1982); Yoder & Layton (1988)
Acquisition
of prelinguistic behaviors may
follow a different course for some children
with severe disabilities
Parents are eager for children to communicate
symbolically
child
who is slow to acquire natural gestures
and vocalizations
Child
who meets/exceeds goals of PMT but is
slow to develop speech.
Use typical naturalistic teaching strategies such
as incidental teaching, mand model and
delayed prompts to teach AAC and spoken
verbal utterances
Incorporate AAC
within prelinguistic
interventions
In beginning AAC instruction, focus on
communicative foundations such as directing
behaviors toward partners and use of gestures
Research is needed to identify optimum
strategies for combining prelinguistic
intervention and AAC
• PECS and spontaneity example
Evidence
that children increase their use of
communicative gestures
Yoder, Warren and colleagues studies:
• Effective for children in low-responsive environment
Fey,
Waren, Brady, Finestack, Bredin-Oja and
Fairchild (2006)
• Significant increases after 6 months of intervention
Warren, Fey, Finestack, Brady, Bredin-Oja (2008)
• Effects did not maintain over time
• Possible differences in effects for children with Down
Syndrome
Brady
and Bashinski (2009)
• research with deafblind children
• Results from 9 children who had relatively good motor
skills
• 2 children with severe motor limitations
Summary:
• All 9 kids with adequate motor skills increased their
initiated communication
Mostly requests
• Effects did not generalize to different contexts
• Less effective for children with severely limited motor
skills
Working
with partners to increase
responsiveness and decrease directiveness
Goal is to promote a context where children
have a need and desire to communicate

It
is very hard to change a person’s behavior.
It is usually easier to learn a new behavior
than to change an old one.
People must be highly motivated in order to
change behavior and maintain that change.
Work
with partner to increase:
• following the child’s lead
• waiting for the child to respond
• listening to the child
Play
with the child face to face, placing few
demands or constraints on the child’s actions.
Imitate the child’s actions and sounds.
commenting about child’s actions, etc.

Parent
observation of
intervention sessions
Working with families that have a child with FXS
Pilot study: 4 families
Ten sessions were held approximately 1 week
apart.
Each session followed the Hanen curriculum but
lessons were individualized. Key components of
the intervention included
• teaching parents to wait for their children to initiate
interactions
• recognizing communication attempts
• following the child’s lead
• providing simplified input
Results:
Three
mothers showed increases in facilitative
interaction style behaviors
Three mothers decreased their number of
utterances per turn
Two children increased the number of different
words produced
