As in reflexive responses to pain, the body sometimes reacts reflexively to ideas alone without the person consciously deciding to take action..., the well-known phenomenon whereby individuals' expectations exert unconscious influence over their motor actions. Even FC users and proponents do acknowledge the possibility of facilitators at times "guiding" users, consciously or unconsciously. Other theorists (Donnellan and Leary, 1995) argue that autism is in significant part characterized by dyspraxia (a movement disorder), and that there exists a synchronistic "dance" to communication in all mammalian social interaction which accounts for the mixed results in validation studies.

  • Mark Mostert (2001) says: "Previous reviews of Facilitated Communication (FC) studies have clearly established that proponents' claims are largely unsubstantiated and that using FC as an intervention for communicatively impaired or noncommunicative individuals is not recommended."

  • The phrase "independent typing" is defined by supporters of FC as "typing without physical support", i.e., without being touched by another person. Skeptics of FC do not agree that this definition of independence suffices because of the possibility of influence by the facilitator. For example, Sue RubinSue RubinSue Rubin is a functionally non-verbal published autistic author who was the subject of the Oscar-nominated documentary Autism Is A World in which she communicated via the controversial communication technique of facilitated communication...., an FC user featured in the autobiographical documentary Autism Is A World, reportedly types without anyone touching her; however, she reports that she requires a facilitator to hold the keyboard and offer other assistance.

  • A new paper from Eric Fombonne is in electronic print at the journal Pediatric Research.
  • The title is ‘Epidemiology of pervasive developmental disorders’
  • Combining all these categories together Fombonne presents a prevalence of 60-70/10,000.
  • ...10 more annotations...
  • Pervasive Developmental Disorders, including Autistic Disorder, Asperger Disorder, Pervasive Developmental Disorder Not Otherwise Specified, and Childhood Disintegrative Disorder.
  • For autistic disorder, Fombonne says: The correlation between prevalence and year of publication was statistically significant and studies with prevalenceover 7/10,000 were all published since 1987. These findings point towards an increase in prevalence estimates in the last 15-20 years.
  • recent autism surveys have consistently identified smaller numbers of children with AS than those with autism within the same survey.
  • How much lower is difficult to establish from existing data, but a ratio of 3 or 4 to 1 would appear an acceptable,
  • We therefore used for subsequent calculations an estimate of 6/10,000 for AS, recognizing the strong limitations of available data on AS.
  • Eight studies provided data on childhood disintegrative disorder (CDD). Prevalence estimates ranged from 0 to 9.2/100,000.
  • The upper-bound limit of the associated confidence interval (4.0/100,000) indicates that CDD is a very rare condition, with about 1 case to occur for every 103 cases of autistic disorder.
  • Current evidence does not strongly support the hypothesis of a secular increase in the incidence of autism but power todetect time trends is seriously limited in existing datasets.
  • Whilst it is clear that prevalence estimates have gone up over time, this increase most likely represents changes in the concepts, definitions, service availability and awareness of autistic-spectrum disorders in both the lay and professional public.
  • The possibility that a true change in the underlying incidence has contributed to higher prevalence figures remains, however, to be adequately tested.
