Surprising language abilities in children with autism
April 28, 2008What began as an informal presentation by a clinical linguist to a group of philosophers, has led to some surprising discoveries about the communicative language abilities of people with autism.
Several years back, Robert Stainton, now a philosophy professor at The University of Western Ontario, attended a presentation by his long-time friend Jessica de Villiers, a clinical linguist now at the University of British Columbia. The topic was Autism Spectrum Disorder (ASD). De Villiers explained that many individuals with ASD have significant difficulties with what linguists call "pragmatics." That is, people with ASD often have difficulty using language appropriately in social situations. They do not make appropriate use of context or knowledge of what it would be "reasonable to say." Most glaringly, many speakers with ASD have immense trouble understanding metaphor, irony, sarcasm, and what might be intimated or presumed, but not stated.
Drawing on his philosophical training, however, Stainton noticed less-than-obvious pragmatic abilities at work in de Villiers' examples, which were drawn from transcripts of conversations with 42 speakers with ASD - abilities that had been missed by clinicians.
Thus began research to more clearly understand and define the conversational abilities and challenges of people with Autism Spectrum Disorder (ASD). Stainton and de Villiers' research, in collaboration with Peter Szatmari, a clinical psychiatrist at McMaster University, has shown that indeed, many individuals with ASD do have "a rich array of pragmatic abilities."
These researchers do not contest the well-established claim that people with ASD have difficulty with non-literal pragmatics, such as metaphors ("Juliet is the sun") or irony/sarcasm ("Boy, is that a good idea"). They have, however, found that many speakers with ASD do not show the same difficulty with literal pragmatics. An example is the phrase, "I took the subway north" from a transcript of a conversation with a research participant with ASD. The use of the word "the" could indicate there is only one subway in existence going north. "The subway" could also be referring to a subway car, a subway system or a subway tunnel. Taking account of the context and the listener's expectations, however, the individual using the phrase was able to convey the specific meaning he intended. That is, he used pragmatics effectively.
In short, Stainton and his colleagues produced surprising evidence to show that speakers with ASD use and understand pragmatics in cases of literal talk, as in the subway example.
Stainton, who is also Acting Associate Dean of Research in the Faculty of Arts and Humanities at Western, says, "It is especially gratifying and encouraging, because this is an Arts and Humanities contribution to clinical research. Without a philosophical perspective, this discovery might not have been made."
Related research allowed de Villiers and Szatmari to develop a rating scale of pragmatic abilities that can be used in the clinical assessment of people with ASD. Stainton says, "In the short term, their new tool will help identify where an individual fits on that spectrum. In the longer term, however, by making use of recent results in philosophy of language, it may contribute to our theoretical understanding of the boundary between knowledge of the meanings of words, and non-linguistic abilities - specifically pragmatics."
Stainton believes that both clinicians who work with people with ASD, and language theorists who are interested in pragmatics for philosophical reasons, will find these results striking.

Autism News and Current Autism Events RSSRobot playmates may help children with autism
Papers delivered at three conferences in the US and Europe this summer report on new research at the University of Southern California Viterbi School of Engineering studying interactions of children with Autism Spectrum Disorders (ASD) with bubble-blowing robots.
Caltech and UNC research finds further evidence for genetic contribution to autism
Some parents of children with autism evaluate facial expressions differently than the rest of us--and in a way that is strikingly similar to autistic patients themselves, according to new research by neuroscientist Ralph Adolphs of the California Institute of Technology and psychiatrist Joe Piven at the University of North Carolina at Chapel Hill.
The first autism disease genes
The autistic disorder, a neurodevelopmental disease first described in 1943, represents a challenge for treatment and a puzzle for research. Alongside Asperger syndrome, a milder form of the disorder, autism is classified in the continuum of various Autism Spectrum Disorders (ASD), all of which are characterized by deficits in language, social interaction, and a strangely restricted and repetitive behaviour (stereotypy).
Researchers link early stem cell mutation to autism
In a breakthrough scientific study published today in the Proceedings of the National Academy of Sciences, scientists at the Burnham Institute for Medical Research have shown that neural stem cell development may be linked to Autism.
Our genome changes over lifetime, Johns Hopkins experts say
Researchers at Johns Hopkins have found that epigenetic marks on DNA-chemical marks other than the DNA sequence-do indeed change over a person's lifetime, and that the degree of change is similar among family members.
Drug reverses mental retardation caused by genetic disorder
UCLA researchers discovered that an FDA-approved drug reverses the brain dysfunction inflicted by a genetic disease called tuberous sclerosis complex (TSC).
'Faulty' brain connections may be responsible for social impairments in autism
New evidence shows that the brains of adults with autism are "wired" differently from people without the disorder, and this abnormal pattern of connectivity may be responsible for the social impairments that are characteristic of autism.
Knowing looks: Using gaze aversion to tell when children are learning
People use eye contact in a variety of ways every minute of every day but how often do you find yourself staring into space with concentrating on an issue or problem? Psychologists now know that people who are carrying out a complex task tend to look away from anyone else who is nearby. They refer to it as 'gaze aversion'.
A Computer That Can 'Read' Your Mind
For centuries, the concept of mind readers was strictly the domain of folklore and science fiction. But according to new research published today in the journal Science, scientists are closer to knowing how specific thoughts activate our brains. The findings demonstrate the power of computational modeling to improve our understanding of how the brain processes information and thoughts.
Research tool can detect autism at 9 months of age
The ability to detect autism in children as young as nine months of age is on the horizon, according to researchers at McMaster University.
