'''Autism''' is a type of pervasive developmental disorder. It is characterized by difficulties with social interaction; difficulties with verbal communication, especially pragmatic language; difficulty processing nonverbal communication such as facial expression; intense, narrow interests; difficulty adjusting to changes in routine; and repetitive behaviors. Other signs include lack of eye contact, delayed or unusual play skills, hypo- or hyper-sensitivity to sensory stimuli, and anxiety.<ref>http://www.webmd.com/brain/autism/development-disorder?page=2</ref> It is usually detected by the time a child is four years old but in some cases, autism goes unnoticed into adulthood. There are many intelligent and talented autistic individuals.<ref>Temple Grandin, "Thinking in Pictures, Expanded Edition: My Life with Autism" amazon link http://www.amazon.com/gp/product/0307275655/ref=wl_it_dp/103-3432247-4184629?ie=UTF8&coliid=I1CWNFSEUCIXQL&colid=49VN3HJC5OQK</ref>  The term '''autism''' was first used in 1912.

There are claims that environmental toxins increase the risk of autism, just as they increase the risk of cancer.  [[New Jersey]] has the highest rate of cancer in the nation, presumably due to a heavy concentration of environmental toxins, and it also has the highest rate of [[autism]].  Autistic patients are observed to have higher levels of metals and other toxins.

Simon Baron-Cohen, director of the Autism Research Centre at the [[University of Cambridge]] (U.K.) says that males and females are hardwired for different behavior, with boys tending to be stronger at mechanics, categorizing and systemizing information, mathematics, etc. and girls stronger at emotionalizing and empathizing.  He has proposed that autism is merely an extreme version of the [[male brain type]], in which the (female) urge to empathize is nearly absent and the brain is almost entirely hardwired for the (male) tasks of systemizing.<ref>Baron-Cohen, Simon.  ''The Essential Difference'', Basic Books 2003.</ref>

Lenny Schafer, editor of the ''Schafer Autism Report'', rejects outright the current characterization of mild social retardation (such as "[[Asperger syndrome|Asperger's syndrome]]") as forms of autism.  He notes that autism is a disability, and if a person is not disabled from participation in society by their condition, in such areas as being able to hold a job or communicate, including communication over the Internet, they are not autistic and should not be diagnosed as such.  He accordingly rejects that there can be such a thing as autistic self-advocacy, as anyone who is truly autistic would not have that ability.<ref>http://www.sarnet.org/</ref>  This view is highly controversial in the field, and has led to the development of the "autistic spectrum" to better characterize and diagnose autism and autism-like disorders.

''Wired'' magazine has referred to autism as a "geek syndrome", or essentially as a form of identity-politics-for-computer-nerds.<ref>http://www.wired.com/wired/archive/9.12/aspergers_pr.html</ref>. Those favoring this interpretation of autism have coined new terminology, including "neurodiversity" for a population with and without autistic individuals , and using the term "neurotypical" for those without autism.

==Interventions and Treatments==

==Interventions and Treatments==

*Applied Behavioral Analysis (ABA) - This is a behavioral intervention which applies the study of behavioral analysis, as well as the tools of this study, toward assisting behaviors of social significance in individuals of many different populations, including children with autism. <ref>http://www.centerforautism.com/getting_started/aba.asp</ref> Applied behavior analysis is used to increase positive behaviors, decrease interfering behaviors, maintain positive behaviors, teach new skills, and generalize new positive behaviors across many different settings, not just in a restrictive classroom or therapy setting. Therapists begin by observing the behaviors of the individual, focusing on skills and behaviors to reinforce or teach, and identifying interfering behaviors to be minimized. They then develop an intervention plan to reinforce the positive behaviors and skills, by using a system of rewards when the individual receiving the therapy exhibits the behavior that the therapist wants to observe. As the individual incorporates more positive behaviors, the therapist may decrease or change the reinforcement as necessary.

As the individual incorporates more positive behaviors, the therapist may decrease or change the reinforcement as necessary.  

*Developmental, Individual difference and Relationship-based (DIR/Floortime) model - This is a relationship-based intervention, developed by Dr. Stanley Greenspan, which focuses on developing a connection with the individual with autism, emphasizing the role his or her interests, emotions, and preferences play in developing an effective treatment. <ref>http://www.icdl.com/dirFloortime/overview/index.shtml</ref> This model emphasizes individual differences in children with autism, and requires caregivers and therapists to approach each child accordingly. It begins with understanding the child's developmental stage, understanding the ways in which the child understands and learns information and processes sensory stimuli, and developing relationships between the child and his or her caregivers and therapists, who tailor their affect and interactions to the child's needs. This model especially emphasizes the importance of parents and caregivers in the process of their child's treatment, because of their unique relationship to the child.

*Treatment and Education of Autistic and related Communication-handicapped CHildren (TEACCH) - This approach was developed in the early 1970s by Eric Schopler and colleagues, and focuses on skil development, as well as fulfillment of human needs such as communication, social interaction, increasing feelings of safety and reducing anxiety, and engaging in productive and enjoyable activities.<ref>http://www.teacch.com/whatis.html</ref> The principles of the TEACCH method of intervention include: understanding the "culture" of autism (what characterizes individuals with autism, such as their thinking patterns and behaviors), developing an individualized approach to intervention for each individual, structuring the physical environment for effective learning, and using visual supports to assist in understanding and retaining routines, structures, and schedules, as well as to make individual tasks understandable.
