Autism Therapy: pivotal response training | Healing Thresholds - 0 views

  • Future research may allow therapists to know in advance which type of applied behavior analysis (ABA therapy) is most likely to work for any given child with autism.
  • This study of six children was designed to see if it is possible to predict which type of ABA therapy will work for which child with autism.
  • The authors were able to predict which children would respond to pivotal response training, but not which ones would respond to discrete trial training. The authors note that all children were first exposed to pivotal response training and then to discrete trial training and this may have influenced the results. Children who liked toys were more likely to respond to pivotal response training than children who did not like toys.

    "When looking for apps for students on the autism spectrum (ASD), it is important to look at all educational apps and not just those that are tagged as autism apps. They have many of the same learning needs that other students have. This list was developed to provide apps based on common learning characteristics and traits that are typical for students with ASD. It is important to remember that all students learn differently and selecting apps should be based on the unique learning needs of the student. This list is only a sampling of apps available for each skill area. This is not, nor is it meant to be a definitive list. This list is intended to give you a starting place and a rationale for picking certain apps."

Auditory Integration Training and Facilitated Communication for Autism -- Committee on ... - 0 views

  • For example, Smith et al16 studied 10 individuals with autism specifically to investigate the effects of facilitator influence and level of assistance on the results of FC. Each subject had six sessions, two with no help, two with partial assistance, and two with full assistance. Results showed that there were no cases of correct responses from the subject unless the facilitator knew the correct response. In addition, numerous responses were typed by the subjects to stimuli that were shown only to the facilitator, and not the subject. Similar results have been found by Regal et al17 and Eberlin et al.1
  • One complication of the use of FC has been the allegation of abuse, particularly sexual abuse, that has been obtained from individuals through the use of FC against third persons. This has generated adverse publicity and caused severely negative consequences for families who may be unsure of the validity of the allegations. Because of legal mandates regarding reports of child abuse, this becomes a critical issue for teachers and pediatricians alike, who may find the credibility of the report highly questionable but are obligated to fulfill their legal responsibilities. Margolin20 notes that although more than 50 such allegations have resulted in legal proceedings, most have terminated before trial. The ethical dilemmas posed by FC for practitioners have been reviewed by Jacobson et al.8
  • It is important for the pediatrician to obtain current data on both AIT and FC as they become available. Until further information is available, the use of these treatments does not appear warranted at this time, except within research protocols.
  •  
    This statement reviews the basis for two new therapies for autism---auditory integration training and facilitative communication. Both therapies seek to improve communication skills. Currently available information does not support the claims of proponents that these treatments are efficacious. Their use does not appear warranted at this time, except within research protocols.

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.

  • 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.

facilitated communication - The Skeptic's Dictionary - Skepdic.com - 0 views

  • Facilitated Communication therapy began in Australia with Rosemary Crossley. The center for FC in the United States is Syracuse University, which houses the Facilitated Communication Institute (FCI) in their School of Education.
  • A very damaging, detailed criticism was presented on PBS's "Frontline", October 19, 1993. The program was repeated December 17, 1996, and added that since the first showing, Syracuse University has claimed to have done three studies which verify the reality and effectiveness of FC, while thirty other studies done elsewhere have concluded just the opposite.
  • Furthermore, FC clients routinely use a flat board or keyboard, over which the facilitator holds their pointing finger. Even the most expert typist could not routinely hit correct letters without some reference as a starting point.
  • Facilitators routinely look at the keyboard; clients do not. The messages' basic coherence indicates that they most probably are produced by someone who is looking at the keyboard.
  • Anyone familiar with Helen Keller, Stephen Hawking or Christy Brown knows that blindness, deafness, cerebral palsy, multiple sclerosis, amyotrophic lateral sclerosis (ALS), or physical or neurological disorders, do not necessarily affect the intellect. There is no necessary connection between a physical handicap and a mental handicap. We also know that such people often require an assistant to facilitate their communication. But what facilitators do to help the likes of a Hawking or a Brown is a far cry from what those in the facilitated communication business are doing.
  • But the vast majority of FC clients apparently are mentally retarded or autistic. Their facilitators appear to be reporting their own thoughts, not their patient's thoughts. Interestingly, the facilitators are genuinely shocked when they discover that they are not really communicating their patient's thoughts. Their reaction is similar to that of dowsers and others with "special powers" who, when tested under controlled conditions, find they don't have any special powers at all.
  • It is interesting that the parents and other loved ones who have been bonding with the patient for years are unable to be facilitators with their own children.
  • And when the kind strangers and their patients are put to the test, they generally fail. We are told that is because the conditions made them nervous. These ad hoc excuses sound familiar; they sound like the complaints of parapsychologists.
  • Skeptics think the evidence is in and FC is a delusion for the most part. It is also a dangerous delusion. Critics have noted a similarity between FC therapy and repressed memory therapy: patients are accusing their parents and others of having sexually abused them. Facilitators are taught that something like 13% of their clients have been sexually abused. This information may unconsciously influence their work.

12 Tips to Setting up an Autism Classroom « Principal Kendrick - 6 views

  • In a world that’s ever changing, routine and structure provide great comfort to a child on the autism spectrum.  Define routines clearly. 
  • Activities are successful when they’re broken into small steps.
  • Make sure children know what to do if they finish ahead of time.  Typically, children with autism do not use free time productively; therefore strive to have as little downtime between activities as possible.
  • ...47 more annotations...
  • 2. Use visuals
  • Remember to keep explanations simple and short about each picture or concentration will wane.   Give written instructions instead of verbal whenever you can.  Highlight or underline any text for emphasis.
  • People with autism like order and detail.  They feel in control and secure when they know what to expect
  • Picture schedules are even more powerful because they help a student visualize the actions.
  • Make sure you have this schedule in a very visible place in your classroom and direct the students’ attention to it frequently, particularly a few minutes before you begin the next activity.
  • Written schedules are very effective for good readers.  These can also be typed up and placed on a student’s desk.
  • 4. Reduce distractions
  • Many people with autism find it difficult to filter out background noise and visual information.  Children with autism pay attention to detail.  Wall charts and posters can be very distracting. 
  • Try and seat children away from windows and doors. 
  • 5. Use concrete language
  • Always keep your language simple and concrete.   Get your point across in as few words as possible. 
  • Avoid using idioms.
  • Give very clear choices and try not to leave choices open ended.  You’re bound to get a better result by asking “Do you want to read or draw?” than by asking “What do you want to do now?”
  • 6. It’s not personal
  • Children with autism are not rude.  They simply don’t understand social rules or how they’re supposed to behave.
  • NEVER, ever, speak about a child on the autism spectrum as if they weren’t present
  • Despite the lack of reaction they sometimes present, hearing you speak about them in a negative way will crush their self esteem.
  • 7. Transitions
  • Children on the autism spectrum feel secure when things are constant.  Changing an activity provides a fear of the unknown.  This elevates stress which produces anxiety
  • Reduce the stress of transitions by giving ample warning
  • Using schedules helps with transitions too as students have time to “psyche themselves up” for the changes ahead.
  • People can be slow when they are learning a new skill until they become proficient
  • Encourage your students to ask each other for help and information
  • Making decisions is equally important and this begins by teaching students to make a choice.  Offer two choices. 
  • When giving a directive or asking a question, make sure you allow for extra processing time before offering guidance.  Self help skills are essential to learn
  • Never underestimate the power of consistency.
  • Avoid this temptation and make sure you allow ample time before you abandon an idea.  Remember that consistency is a key component of success.  If you’re teaching a student to control aggression, the same plan should be implemented in all settings, at school and at home.
  • 9. Rewards before consequences
  • We all love being rewarded and people with autism are no different.  Rewards and positive reinforcement are a wonderful way to increase desired behavior
  • If possible, let your students pick their own reward so they can anticipate receiving it.
  • There are many reward systems which include negative responses and typically, these do not work as well.
  • Focusing on negative aspects can often lead to poor results and a de-motivated student.  When used correctly, rewards are very powerful and irresistible
  • Every reward should be showered in praise.  Even though people on the spectrum might not respond typically when praised, they enjoy it just as much as you!
  • 10. Teach with lists
  • Teaching with lists sets clear expectations.  It defines a beginning, middle and an end.
  • People on the autism spectrum respond well to order and lists are no exception.  Almost anything can be taught in a list format.
  • While typical people often think in very abstract format, people on the spectrum have a very organized way of thought.  Finding ways to work within these parameters can escalate the learning curve.    
  • 11. Creative teaching
  • It helps to be creative when you’re teaching students with autism.  People on the spectrum think out of the box and if you do too, you will get great results.
    • Tero Toivanen
       
      Exactly!
  • Often, people with autism have very specific interests.  Use these interests as motivators.
    • Tero Toivanen
       
      This is how I work! It's works!
  • Another great strategy to use is called “Teaching with questions”.  This method keeps students involved, focused and ensures understanding.
  • Another great way of teaching is by adding humor to your lessons.  We all respond to humor.
    • Tero Toivanen
       
      When you feel well, your students feel well also and learn better!
  • 12. Don’t sweat the small stuff
  • The final goal is for children to be happy and to function as independently as possible.
  • Don’t demand eye contact if a student has trouble processing visual and auditory information simultaneously.
    • Tero Toivanen
       
      It may even be painful for the student... There are research about this issue.
  • By correcting every action a person does, you’re sending a message that they’re not good enough the way they are.  When making a decision about what to correct, always ask yourself first, “Will correcting this action help this person lead a productive and happy life?”

Autism Information - Autism Information You Need To Know - 1 views

  • There are plenty of myths about autism spectrum disorders out there.
  • But even those of use who are well-grounded in autism basics may be surprised by some of these facts, which are emerging from recent research.
  • We do know what causes autism -- but only in about 20% of cases.
  • ...8 more annotations...
  • Quite a few children who are diagnosed with autism at a very young age are no longer diagnosable with autism by the time they’re school-aged.
  • Whatever the reasons, many children who are diagnosed with autism as toddlers will not be diagnosable by the time they're in fifth grade.
  • Early intervention (diagnosis and treatment prior to age three) is very helpful indeed, but there is no “window of opportunity” that slams shut at a certain age. Thus, even children who are diagnosed later or receive less early intervention may do quite well in the long run.
  • Early intervention does, however, provide a now-or-never opportunity to allow non-verbal children to develop some kind of useful tool for communication (picture cards, signs, or even spelling boards).
  • There is no official “cure” for autism. In fact, researchers like Dr. Susan Levy at Children’s Hospital of Philadelphia argue that even when a young child is no longer diagnosable on the autism spectrum, he is probably still autistic.
  • Late talking is not an indication of a poor prognosis.
  • Children with autism may or may not be visual thinkers. Thus, school programs designed with visual thinking in mind may or may not be appropriate for any individual child with autism.
  • After many years of research, we still don’t know which treatments are most effective for which children -- or whether one treatment is more effective than another. Behavioral interventions are the best-researched treatments for autism, but even top scientists acknowledge that developmental interventions may or may not be equally useful for any given child. Meanwhile, only two drugs -- Risperdal and Abilify -- have been approved for use with children on the autism spectrum, and neither addresses “core” issues of autism (social/communication deficits).

The Mirror Neuron Revolution: Explaining What Makes Humans Social: Scientific American - 0 views

  • In recent years, Iacoboni has shown that mirror neurons may be an important element of social cognition and that defects in the mirror neuron system may underlie a variety of mental disorders, such as autism.
  • Mirror neurons are the only brain cells we know of that seem specialized to code the actions of other people and also our own actions. They are obviously essential brain cells for social interactions. Without them, we would likely be blind to the actions, intentions and emotions of other people.
  • The way mirror neurons likely let us understand others is by providing some kind of inner imitation of the actions of other people, which in turn leads us to “simulate” the intentions and emotions associated with those actions. When I see you smiling, my mirror neurons for smiling fire up, too, initiating a cascade of neural activity that evokes the feeling we typically associate with a smile.
  • ...5 more annotations...
  • In 2006 your lab published a paper in Nature Neuroscience linking a mirror neuron dysfunction to autism. How might reduced mirror neuron activity explain the symptoms of autism?
  • Reduced mirror neuron activity obviously weakens the ability of these patients to experience immediately and effortlessly what other people are experiencing, thus making social interactions particularly difficult for these patients. Patients with autism have also often motor problems and language problems. It turns out that a deficit in mirror neurons can in principle explain also these other major symptoms. The motor deficits in autism can be easily explained because mirror neurons are just special types of premotor neurons, brain cells essential for planning and selecting actions. It has been also hypothesized that mirror neurons may be important in language evolution and language acquisition.
  • Thus, a deficit in mirror neurons can in principle account for three major symptoms of autism, the social, motor and language problems.
  • There is convincing behavioral evidence linking media violence with imitative violence. Mirror neurons provide a plausible neurobiological mechanism that explains why being exposed to media violence leads to imitative violence.
  • I think there are two key points to keep in mind. The first one is the one we started with: mirror neurons are brain cells specialized for actions. They are obviously critical cells for social interactions but they can’t explain non-social cognition. The second point to keep in mind is that every brain cell and every neural system does not operate in a vacuum. Everything in the brain is interconnected, so that the activity of each cell reflects the dynamic interactions with other brain cells and other neural systems.
  •  
    In recent years, Marco Iacoboni, a neuroscientist at the University of California at Los Angeles, has shown that mirror neurons may be an important element of social cognition and that defects in the mirror neuron system may underlie a variety of mental disorders, such as autism.

A Family United For The Autistic: 15 Yr Old Aspie Talks About Autism - 0 views

  • Autism gives many unique traits to an individual, and many of these people go on to do great things (it is said Isaac Newton, Albert Einstein, Bill Gates, and other innovators and scientists had forms of autism). I can’t speak for others - maybe they do want to rid themselves of their condition. But as for the parents and individuals making the decision, think about it: do you honestly want a cure that is going to change the individual you are?

Autistic Aphorisms: Enhanced Perception in Savant Syndrome - 0 views

  • Mottron team did not shy away from suggesting that the features of savant syndrome could serve as an entryway into understanding all forms of autistic perception and cognition, savant like or not. This effectively removed savant syndrome from being the freak sideshow of autism and elevated it to the status of being a key element for understanding the condition.
  • it is orientation towards structure and pattern that determines the essential characteristics of autistic perception and cognition.
  • Not weak central coherence. Not damaged executive functioning. Not a missing theory of mind. Not a masculinized brain. Orientation to pattern and structure is the key to understanding autistic perception—an approach that is productive towards autistic interests and abilities, not destructive, as is the case for nearly every other competing theory. The Mottron team's emphasis on pattern-oriented perception in autistic individuals is a helpful step forward in understanding autistic individuals as they truly are.
  • ...5 more annotations...
  • all the success stories related inside the pages of EPSS are accompanied by fortuitous exposure to various forms of structured material, clearly marking out the most promising path for autistic development and growth.
  • And of course these discussions fly in the face of the current clamor for early intervention in autism, where it would seem the goal is always to yank the autistic child away as early as possible from his or her preferred method of engaging the world, and substitute instead an intense bombardment of socially based indoctrination, hoping to turn the child around while there is still time for the “malleable” brain to be re-molded.
  • In my opinion, it is no mere coincidence that the very same elements that stand at the core of the Mottron team's affirmative description of autistic perception and cognition are also the very same elements that stand at the core of humanity’s sudden departure off the savannah and leap into the modern world.
  • Admittedly, a thorough discussion of such a topic would be much too large for inclusion in an academic research paper such as EPSS, but the fact that the Mottron team does not mention, or even hint at, the connection between the features of autistic perception and the features of human cognitive history leave it unclear whether the team has ever considered such a connection.
  • At this point in time, the Mottron team seems to be the only autism research team heading in a positive and enlightening direction—a direction that is constructive for autistic individuals everywhere—and I look forward to all their future contributions.

Early intervention for toddlers with autism highly effective, study finds - 1 views

  • The study, published online today in the journal Pediatrics, examined an intervention called the Early Start Denver Model, which combines applied behavioral analysis (ABA) teaching methods with developmental 'relationship-based' approaches.
  • The five-year study took place at the University of Washington (UW) in Seattle and was led by Dawson, then a professor of psychology and director of the university's Autism Center, in partnership with Rogers. It involved therapy for 48 diverse, 18- to 30-month-old children with autism and no other health problems.
  • At the conclusion of the study, the IQs of the children in the intervention group had improved by an average of approximately 18 points, compared to a little more than four points in the comparison group. The intervention group also had a nearly 18-point improvement in receptive language (listening and understanding) compared to approximately 10 points in the comparison group. Seven of the children in the intervention group had enough improvement in overall skills to warrant a change in diagnosis from autism to the milder condition known as 'pervasive developmental disorder not otherwise specified,' or PDD-NOS. Only one child in the community-based intervention group had an improved diagnosis.

Genes implicated in twins' autism | The Autism News - 1 views

  • Researchers have known for years that when one identical twin has autism, the other is also likely to be diagnosed with it – evidence that autism likely has a genetic component.
  • Researchers at Kennedy Krieger Institute studied 277 pairs of twins and found that when one identical twin had the disorder, the other developed it 88 percent of the time; for fraternal twins, that figure was 31 percent.
  • Despite this progress in unlocking the mysteries of autism, scientists have simply confirmed that there are likely numerous genetic links to autism.
  • ...9 more annotations...
  • Each discovery explains just a tiny fraction of autism’s causes. Researchers think the great majority – 90 percent – of autism cases have a genetic cause, but they’ve found fewer than 10 percent of the triggers.
  • researchers have found about 50 genes so far that might be tied to autism, which explain very few cases, he said.
  • Autism isn’t one disease; it’s too individual to locate just one genetic cause. It’s not like cystic fibrosis, a disorder for which researchers have identified one gene – and tests to diagnose it.
  • autism researchers envision that a wide variety of gene defects are responsible for the symptoms collectively known as autism spectrum disorders. The disabilities, different in each child, range from the mild Asperger syndrome to more severe impairments in social interaction and communication.
  • “It’s going to take some work before we understand the true causes of autism,” he said. “We need to make much more headway to ever have enough understanding so that patient management and therapies can be improved.”
  • None of the new findings explains why more children are being diagnosed with autism. Genes, said Goldstein, tell only part of the story.
  • “The idea is there is an environmental interaction with the genetic component,” he said.
  • Autism may be inherited to some degree, but even twin studies show that not all sets of identical twins have autism. And when they do, they don’t always have the same severity of the disorder

How to unleash your brain's inner genius - life - 03 June 2009 - New Scientist - 0 views

  • A flurry of research published earlier this year in the journal Philosophical Transactions of the Royal Society B paints a very different picture. It turns out that these skills are far more common than previously thought. They may even arise from traits found in the general population, implying that savants are not fundamentally different from the rest of us. What's more, these skills may only blossom after years of obsessive practice, raising the question of whether many more people might cultivate similar skills, if only they had the motivation.
  • One of the biggest clues to the origins of savant talent lies in the fact that savants are far more common within the autistic population than among people with other mental difficulties.
  • Previously, about 1 in 10 people with autism were thought to have a special ability but in April, Patricia Howlin at the Institute of Psychiatry at King's College London found a much higher figure in the autistic adults she surveyed for savant skills or an exceptional cognitive ability.
  • ...11 more annotations...
  • Savant skills included more fully developed talents, such as being able to name the elevation of both the sun and the moon at any time of day, on any specified date; being able to name the day of the week for any date in the distant past or future (a talent known as calendrical calculation) and perfect pitch. Importantly, the abilities and the skills had to be exceptional by the standards of the general population, but also well above the individual's overall level of ability. In total, roughly 30 per cent had some kind of special ability (Philosophical Transactions of the Royal Society B, vol 364, p 1359).
  • For musical savants like Paravicini, Happé suggests that a bias towards small details might have led their developing brains to focus more on the exact notes than the overall melody, leading to perfect pitch and an exceptional musical memory. In art, a focus on small regions of a picture could lead to accurate perspective drawing.
  • Most people find this harder when they are shown an unsegmented version of the pattern versus a segmented one, but people with autism don't have this preference, demonstrating their skill at seeing a whole in terms of its parts even if there are no obvious dividing lines (see diagram). "It shows they are able to do the segmentation in their minds," says Winner. The precocious realists did not have this preference either, indicating a talent for realistic drawing may arise from this isolated trait commonly found in autism (Philosophical Transactions of the Royal Society B, vol 364, p 1449).
  • Although these results help to pinpoint exactly what it is about autism that predisposes people to talent, it's still not clear why an eye for detail is more common in autistic people in the first place. Clues might lie in the work of Simon Baron-Cohen from the University of Cambridge, which suggests that people with autism are "hypersensitive" to sensory information
  • Daniel Tammet, a prodigious savant who has memorised pi to 22,514 digits, believes his own talents have arisen from a special ability to connect different pieces of information together. "Savant abilities are linked to a highly associative type of thinking, an extreme form of a kind that everyone does - examples would include daydreaming, puns and the use of metaphors," he says.
  • The few studies of savant brains certainly suggest they are physically different from the average brain. For example, when Happé and Wallace studied the brain of a savant gifted at art, calendrical calculation and memory, they found his cortex was thicker in the areas associated with visuospatial processing and calculation and thinner in other regions associated with social cognition, compared with people who were neither savants nor autistic. But whether these differences were innate or grew with lifelong practice was still unclear.
  • The answer to that question may come from an unlikely source - a study of London taxi drivers who have acquired an encyclopedic memory of the streets of London known as "the Knowledge". Given that taxi drivers must remember the layout of 25,000 streets and the location of thousands of places of interest, and retrieve the information instantaneously, some researchers like Happé believe the Knowledge qualifies as a savant-like skill.
  • Eleanor Maguire and colleagues at the Institute of Neurology at University College London and colleagues found that drivers with the Knowledge have a bigger rear hippocampus than bus drivers and adults who do not drive taxis. In addition, the hippocampus appears to be larger the longer a taxi driver has been working, and shrinks once they retire (Philosophical Transactions of the Royal Society B, DOI: 10.1098/rstb.2008.0288).
  • In fact, it seems the remaining mystery is not so much how savants achieve their talents, but what drives them in the first place. "Motivation is a big unknown," says Wallace. "It's an enormous driving force in giftedness and in savants, but we don't know a lot about it."
  • One person who has something of an inside view on what contributes to savant ability is Paravicini's mentor, Adam Ockelford, a professor of music at Roehampton University in London who has watched Paravicini's talent blossom since the age of 4. When they first met, Paravicini was entirely self-taught and bashed at his plastic keyboard with his fists and elbows to reproduce the sounds he was hearing. It was only after years of practice that his technical skills developed.
  • But as researchers like Wallace have suggested, Paravicini seemed motivated way beyond the average music student. In fact, he seemed to be playing as if his life depended on it, and Ockelford thinks it's this that truly sets savants apart from their peers. "The survival instinct gets turned with extraordinary force into something else - in Derek's case music," says Ockelford. "When people see Derek, they think it is amazing, almost religious. But to me, it's mainly just hard work."
  •  
    But now researchers are beginning to unearth clues as to how savants' formidable brains work, and that in turn is changing our view of what it means to be a savant.

NeuroLogica Blog » The Genetics of Autism - 0 views

  • What this means is that there is likely to be a complex set of many factors that contribute to ASD - not one single cause.
  • The same exact situation is true for other entities, like schizophrenia and attention deficit disorder (ADD).
  • One difference, however, is that schizophrenia and ADD likely represent changes to particular parts of the brain, while autism is likely due to changes in the global architecture of the brain.

  • Getting back to the genetics of autism, current models are therefore consistent with what is being found when the genetics of autism is researched - researchers are finding many genes that predispose to autism in a subset of cases but no single or simple universal cause. At present, 133 different gene variants have been linked to autism.
  • This new research, conducted by Dr. Hakon Hakonarson of the Children’s Hospital of Philadelphia, is a genome wide analysis involving about 10,000 individuals.
  • The results are especially significant because the variants lie between two genes, called CDH9 and CDH10, which are known to play an important role in forming nerve connections in the brain.
  • The gene variants that correlated with ASD are for proteins that are involved in the process of neurons forming connections with each other. There is already other lines of evidence that suggest what is different in ASD brains is a decrease in the amount of interconnectedness and communication among neurons. It is therefore likely no coincidence that this study found genetic correlations for proteins involved with neuronal connections.
  • This also is compatible with the finding that many separate genes are potentially involved with ASD - for there are many separate genes and processes involved with forming and maintaining neuronal connections.
  •  
    A new genome-wide analysis of families with autism has found significant gene associations, adding to the growing evidence for strong genetic contribution to autism.

Asperger Syndrome Tied to Low Cortisol Levels - 0 views

  • Low levels of a stress hormone may be responsible for the obsession with routine and dislike for new experiences common in children with a certain type of autism.
  • The body produces cortisol, among other hormones, in stressful situations. Cortisol increases blood pressure and blood sugar levels, among other duties, to signal the body's need to adapt to changes occurring around it.
  • People with Asperger syndrome notably have very repetitive or narrow patterns of thought and behavior, such as being obsessed with either a single object or topic. Though tending to become experts in this limited domain, they have otherwise very limited social skills, according to the study.
  • ...4 more annotations...
  • "Although these are early days, we think this difference in stress hormone levels could be really significant in explaining why children with AS are less able to react and cope with unexpected change,"
  • If these Asperger symptoms are caused primarily by stress, caregivers could learn to steer children away from situations that would add to anxiety, the researchers said.
  • "This study suggests that children with AS may not adjust normally to the challenge of a new environment on waking,"
  • The researchers, whose findings were published in the journal Psychoneuroendocrinology, will next study if this lack of cortisol upon waking also occurs in children with other types of autism.

Facilitated Communication - 0 views

  • Facilitators who work closely with individuals with autism, as well as other developmental disabilities (e.g., mental retardation, cerebral palsy, etc.) report that individuals with little or no language are fully expressive about life experiences, thoughts, feelings, choices, preferences, and decisions, when allowed to communicate through facilitation.
  • Biklen and other proponents of facilitated communication have been strongly opposed to objective, empirical validity testing. They maintain that testing undermines the individual's confidence, places him or her under pressure, and introduces negativism that destroys the communicative exchange.
  • Rather, under the surface of autism is a person with full cognitive faculties. Smith and Belcher (1993) indicate that much of this suggests a basic unwillingness on the part of families, professionals, and caregivers to accept the individuals with disabilities for what they are, thus diminishing the value of the individual in a way that the disability itself could not have.
  • ...12 more annotations...
  • Thompson (1993) describes facilitated communication as a classic example of the self-fulfilling prophecy. The facilitator wants to believe that the person with a severe cognitive and language disability is actually of normal to superior intellectual ability. Parents especially want to believe that a way has been found to finally unlock the door to their real son or daughter.
  • In short, people want facilitated communication to work.
  • Advocates of facilitated communication often respond to naysayers, "It can't hurt to try it." Biklen agrees, "It is not harmful to teach people to communicate through pointing." However, he qualifies his claim with the caveat that "it can be harmful if the facilitator over interprets, does not monitor the person's eyes, facilitates when the person is looking away, is not sensitive to the possibility of guiding the person, and asks leading rather than clarifying questions."
  • Some argue that "false communication" may distort beliefs, understanding, and rehabilitative approaches to persons with autism and other developmental disabilities.
  • Additionally, facilitated communication in the past few years has been the source of many contested abuse allegations, usually allegedly reported by an individual with very limited unassisted communication skills against a family caregiver or caregivers.
  • There are at least 50 legal cases in the U.S. involving allegations of sexual abuse produced through facilitated communication (Berger, 1994). Several such cases have already occurred in Australia, and some have arisen in Europe (Green, 1992).
  • With the exception of three empirical studies (Intellectual Disability Review Panel, 1989; Calculator and Singer, 1992; and Velazquez (in press)) which provide preliminary validation of facilitated communication, most of the support for the validity of facilitated communication is based on anecdotal reports.
  • Unfortunately, validity questions surround anecdotal reports of facilitated communication. In general, these reports lack the controls necessary to rule out experimenter biases, reliability concerns, and threats to validity (Cummins and Prior, 1992; Jacobsen, Eberlin, Mulick, Schwartz, Szempruch, and Wheeler, 1994).
  • Although Biklen (1990) admits that facilitator influence is a real possibility, facilitated communications are typically reported as though they are the words of the person with a disability.
  • Without exception, these empirical studies have questioned the authenticity of the communication as truly coming from the individual versus the facilitator.
  • Interdisciplinary Party Report (1988) and the Intellectual Disability Review Panel (1989) both of which examined the source of facilitated communications produced by persons in Australia, and found strong evidence that responses obtained through facilitation were influenced by the facilitator.
  • Gina Green, Director of Research for the New England Center for Autism and Associate Scientist for the E.K. Shriver Center for Mental Retardation, Inc., has reviewed over 150 cases where empirical testing was performed and cites 15 independent conduct evaluations involving 136 individuals with autism and/or mental retardatiion who were alleged to have been taught to communicate via facilitated communication. In none of the cases were investigators able to confirm facilitated communication by the 136 individuals.
