Do Kids With Autism Eventually Learn to Speak?
19/03/13 15:25 Filed in: autism
An exciting headline that recently caught my eye claimed that a recent study published in Pediatrics found that most children with autism eventually do learn to speak. This claim piqued my curiosity because autism and language is a very big deal; therefore, I had to actually see what the authors in the study found.
Here’s my review of Predictors of Phrase and Fluent Speech in Children with Autism and Severe Language Delay, a study based on the Simon Simplex Collection (SSC), which is a large multisite data base project collecting a variety of information on families who are in some way affected by autism.
Wodka, Mathy and Kalb set out to ask two questions:
Using a very large sample of 372 children with Autism Spectrum Disorder (ASD), these researchers found that higher IQ and less social impairment were good predictors of eventual ability to speak in phrases. They report that 70% of the children in the database eventually learned to speak in phrases by eight years of age, and that 50% of the entire sample eventually became fluent speakers.
For the moment, let’s put aside the few methodological problems with the study (e.g., over-reliance on retrospective parental reporting by using a parent interview [ADI-R] and a parent checklist [Child Behavior Checklist]) and take what these researcher claim as accurate. Every parent is still waiting for the answer to the burning question:
Which treatment programs created such great outcomes? What makes kids with autism talk?
Regrettably, here’s where the study falls short. Although the researchers tip their hat to Behavioral Treatment when they mentioned a prior study by Pickett and colleagues that found participation in Behavioral Intervention programs and IQs over 50 were predictors of developing speech after 5 years of age, these researchers did not actually measure the effect of behavioral treatment programs on the acquisition of speaking in phrases. This omission is unfortunate because the reader is left with the impression that as long as the child has an average non-verbal IQ, and evidence of social interest, the child is likely to spontaneously speak in phrases without intervention. This is an erroneous conclusion because the study did not measure whether the children were in treatment or not. In other words, kids don’t magically attain speech when afflicted with the debilitating disorder of autism - there is usually a lot of heavy lifting involved, in the form of lengthy, intensive and expensive behavioral treatment.
Going forward, I would like to see the researchers control for treatment when studying our children. The study is only valuable if we know which treatments create the outcome of 50% of the entire sample eventually becoming fluent speakers!
One heartening finding in the Wotka et al. study is that there was no relationship found between “stereotyped behavior/repetitive interests” and language acquisition. The take-away message here is that we shouldn’t look at children who are hard to reach because self-stimulatory behavior is blocking the world out as somehow being less able to acquire language.
Children with autism most certainly can acquire language, as long as they have access to quality treatment for the disorder.

Wodka, Mathy and Kalb set out to ask two questions:
- What is the rate of language acquisition of children with autism who, by age 4, had not put words together in phrases? and ...
- What factors did predict when these children would learn to speak in phrases?

Will my kid EVER talk?
16/11/11 08:56 Filed in: autism | Asperger's Syndrome
One of the first questions that parents of newly diagnosed children often ask is: will my child ever speak? No professional really wants to touch that question with a ten foot pole because the answer is: it depends. I like to share what I’ve learn over 20 years of reading about this topic in the academic literature, speaking to thousands of parents of children with autism, and personally observing several dozen children with autism in behavioral treatment programs. I need to preface my opinions in this post by saying that I’m talking about children with autism, not Asperger’s syndrome (children with Asperger’s syndrome need to work on language as well; however, they have a much easier time improving their language abilities than children with autism).
Echolalia (including Delayed Echolalia)
If your child cannot use language to communicate but is able to repeat things people say, or can sing songs and actually pronounce words or the lyrics of a song, you should be very happy! With much hard work, and a qualified Behavioral Consultant and/a Behavioral Speech and Language Pathologist (SLP) your child will likely gain the ability to use language functionally. The child’s ability to use language will be highly dependent on the amount of time devoted to communication (and a once a week, one hour treatment session is generally not sufficient). Speech and language must be incorporated into an intensive program designed by a qualified Behavioral Treatment Consultant. If you have only recently established an intensive program for your child, at this point the full potential of your child is impossible to predict. After a few years of treatment, it will become much clearer to you, and the professionals in your orbit, regarding how fluent your child may become in future. So, my advice is not to inherit the future prematurely. Concentrate on maintaining a great treatment program with a heavy emphasis on speech and language!
Apraxia
There is a small subset of children with autism who also suffer from Apraxia, which is a difficulty in actually creating the verbal utterances required to speak. Apraxia occurs in children with and without autism. If a child with autism is Apraxic, the child will need a behavioral Speech and Language Pathologist to work with the child to teach how to create the individual sounds that comprise letters and words. This work should be part of an intensive program, where the SLP is a consultant to a team of behavioral therapists who practice the exercises designed and introduced by the SLP. There is controversy in the literature regarding the rare incidence of Apraxia amongst children afflicted with autism; however, if it is your child suffering from both, the prevalence of Apraxia in autism is irrelevant to you.
Aphasia
There is a subset of children with autism who also suffer from Aphasia: they cannot remember words, even after they are taught. A good behavioral SLP will be able to diagnose whether the child with autism also suffers from this syndrome. Although not common in children with autism, it is important to know whether the child suffers from Aphasia because the SLP, Behavioral Consultant and parent are going to have to agree on a strategy to attack the child’s communication difficulties. The challenge to create meaningful language is greater when Aphasia is added to the mix; however, working intensively on language is still crucially important for the child.
One very promising piece of research that was published by Smith et al. 1997, demonstrates that even the most severely affected children with autism can gain enough language to speak in words, label objects and express needs orally. Whether the children in this study suffered from Apraxia or Aphasia is less clear; however, these were children who had NO speech whatsoever at intake.

Can Autism and Bilingualism Co-exist?
17/10/11 09:50 Filed in: autism | Asperger's Syndrome
A study has just been conducted on twenty-eight children with autism, fourteen of whom are from bilingual families and fourteen who are not. From this study, the authors claim that bilingual children with autism can function “successfully” as bilingual.
