NeuroLogica Blog » Facilitated Communication Persists Despite Scientific Crit... - 0 views

  • Facilitated Communication (FC) is a technique for allegedly aiding those with communication impairment, such as some people with autism, to communicate through typing or pointing at a letter board. The idea is that some children have greater cognitive ability than is apparent through their verbal skills, but they lack the motor skills to type or write. The facilitator in FC is trained to hold and support their client’s hand, to help stabilize it, so that they can type out their thoughts.
  • FC was enthusiastically embraced by the special education community in the late 1980s and early 1990s but problems quickly emerged, namely the question of authorship – who is doing the communicating, the client or the facilitator?
  • The scientific evidence came down clearly on one side of that debate – it is the facilitator who is the author of the communication, not the client.

  • A 2001 review by Mostert came to the same conclusion – that the evidence supports the conclusion that the facilitators are the authors of communication in FC.
  • The strategy here is obvious – studies that directly and objectively confront the key question, who is authoring the writing in FC, gave an answer proponents did not like. They therefore shifted to indirect inference which is more amenable to judgement and qualitative analysis so that the desired results can be manufactured.
  • FC continues to exist on the fringe of legitimate science, but continues to fool journalists, patient advocates, and even physicians.
  • It is sad that FC continues to survive despite the overwhelming scientific evidence that it is not a legitimate method of communication, but rather an elaborate exercise in self-deception.  It is a useful example of how powerful and subtle self-deception can be, and also of the ways in which scientific evidence can be manipulated to generate a desired outcome.

New Study: Autism has Multiple Genetic Roots | Suite101 - 3 views

  • The study’s major finding was that children with ASD have significantly more CNVs affecting their genes than children without ASD. Children with ASD have 20 percent more CNVs in general, and 70 percent more CNVs impacting genes known to be associated with ASD or cognitive problems. Significantly, many of the genes that are affected control important functions such as cell proliferation and cell-to-cell communication.
  • Some of the newly discovered genetic variants are inherited, and are found in parents or siblings of children with them. Others, however, seem to have originated spontaneously in the affected child, and do not appear in other family members.
  • While these findings add significantly to the scientific understanding of the genetic and biological underpinnings of ASD, the immediate usefulness is limited. That’s because there are a very large number of CNVs, and each child shows a different pattern of genetic changes. Each of these changes is rare; no CNV showed up in more than one percent of the children studied.

  • “This will lead to a paradigm shift in understanding the etiology of autism,” says Stephen Scherer, a senior scientist at The Hospital for Sick Children in Toronto, Canada. “Until now, most scientists thought individuals with autism shared common genes. We now think each person has his own rare variations.”
  • If significant CNVs show up, behavioral treatment can be started early. That has been shown to improve children’s outcomes significantly. “If we provide stimulation early, while the brain is still plastic, we can improve cognitive development, social interaction and communication,” says Geri Dawson, Chief Science Officer of Autism Speaks, the major sponsor of the research project.
  • What this new research suggests is that autism and ASD probably result from the interaction between many different genes and a child’s environment. Rather than search for one single cause and one “magic bullet,” researchers will try to find as many significant genetic variants as possible, link them to the biological functions and pathways they control, and then search for medications that can improve or normalize the functioning of damaged pathways.
