Our journey to adopt our daughter was not an easy one
Children with childhood
apraxia of speech cannot easily execute and/or coordinate oral-motor movements
to combine the consonants and vowels necessary to form words. Asking children to
imitate whole words would be setting them up for failure. Just like any other
task that is difficult to master, the task of speaking can be broken down into a
more simplified one, in this case word approximations.
By examining how children
first learn to speak, we can observe that many of the early vocabulary begins
with word approximations such as, baw for ball, or bah for bottle, or even wawa
for water. Children with CAS who have performed little babbling or practice as
infants, may not be able to change what they hear and understand, into the motor
act of speaking those words. By simply offering children with CAS the
opportunity to attempt word approximations using the consonants and vowels
already in their repertoire, successful attempts at words are achieved,
reinforced, and rewarded by the listeners comprehension, and thus their response
to the child's needs and desires. Through shaping, cueing, and fading techniques,
children with CAS can gradually move into whole words, phrases and sentences.
One can evaluate the
consonant and vowel patterns of children by asking them to imitate, moving in a
hierarchy from simple to complex vowel and consonant combinations to obtain a
profile of the child's motor-speech proficiency. Then, through practice of this
hierarchy of consonant and vowel patterns, the children gain verbal praxis
skills for the ultimate goal of successful verbal communication.
Beyond the workout of
practicing consonant-vowel patterns in real words is the important aspect of
functional communication. As soon as the child has any type of an approximation
for a word, it should be encouraged and reinforced by the appropriate response
of the listener (i.e., giving the child juice for attempting doos or oos for
juice). In this approach, however, we do not necessarily wait for the child to
use an approximation independently, though that is certainly the optimal goal.
We actually assist them with imitation, cues, prompts or any possible way to
help them make their best word approximation attempt. We also help to script the
children directly into two or three-word combinations almost immediately, even
if every word is only approximated, such as in I want .., being scripted as Ah
wah
This approach encompasses
aspects of behavior modification (shaping, cueing, fading) for successful
approximations, as well as our knowledge of phonological processes, which are
the way young children tend to simplify adult forms of words. Such phonological
concepts as final consonant deletion, cluster reduction, vowel neutralization,
to name a few processes, are what we rely upon to decide how a word can be
simplified based upon typical speech development. Every word can be reduced to
its shell (this concept of word shells was introduced to me by Ms. Carole Goff,
M.A., CCC/SLP). For instance, the word bottle, can be broken down like this:
bottle
bah-do
bah-o
bah-bah
bah
Choosing the childs highest
successful imitation and reinforcing it (ideally giving the child the bottle),
offers them a chance at successful verbal communication rather than only
accepting the full word which may not yet be a possibility. This approach also
encompasses techniques gleaned from the research and work accomplished by many
speech and language pathologists who work with individuals exhibiting acquired
apraxia of speech. These techniques include using melody and gestures to take
the pressure off of the volitional muscle control system. Occupational
therapy/sensory integration techniques of direct stimulation to the oral
musculature and using gross-motor activity to propel the entire motor system to
activate verbal-motor skills are also valuable to this approach.
The Kaufman Speech Praxis
Treatment Approach is also becoming highly successful for children with CAS on
the spectrum of autism. Dr. Vincent Carbone, Ed.D., BCBA and Ms. Tamara Kasper,
MS/CCC-SLP, BCaBA, are currently researching and adapting the KSPT techniques
specifically through Applied Verbal Behavior, employing methods from B.F.
Skinner (1959) and Sundberg and Partington (1998). The changes for children with
autism are largely due to the fact that it can be more difficult to move along
the hierarchy of word approximations, as there is more work involved in
extinguishing and replacing the first learned word approximation and shaping it
toward the ultimate goal of the full word. Dr. Carbone also utilizes the method
of stimulus-stimulus pairing to move non-verbal (yet vocal) children into the
ability to imitate CV patterns, which prepares them for the KSPT approach.
Through the workout,
scripting, and ultimately improving word retrieval, grammatical skill
development and general formulation skills, children with CAS can become
effective verbal communicators.
