Autism spectrum disorder is a social behavior disorder that affects approximately 1 in 100 people. Its diagnosis is made by referral, for a formal evaluation which will generally be multidisciplinary. Autism spectrum disorder is an incurable disorder, but people with autism spectrum disorder can be helped through the use of intervention therapy and various medications. These therapies generally teach the child how to cope with various social situations, while medications are used to neutralize brain functions related to autism spectrum disorders. In 1911, the term autism was first coined by a psychiatrist named Eugene Bleuler. He used this term to describe patients with schizophrenic traits who withdraw from social contact. However, in 1943, Leo Kanner suggested that children with certain personality characteristics had autism. It was this study that defined autism spectrum disorder as a disease in itself and not a branch of schizophrenia as previously thought. This is the development of autism as we know it today. In 1944, Hans Asperger described four boys as autistic. These boys showed traits of what we now call Asperger's syndrome. Over time, two of the main theories of autism spectrum coherence disorders have been developed, one being theory of mind (ToM), the other being low central coherence (WCC). ToM is the ability to connect mental states, intentions, beliefs, knowledge, pretenses, and desires. One of the most influential people to make statements in the field of ToM regarding autism spectrum disorder was Alan Leslie. He proposed that autistic children lack ToM. This idea came from an experiment done by Baron-Cohen, Leslie and Fr...... middle of paper ...... uh mess. Pellicano, Maybery, Durkin, and Maley (2006) considered that COE may occur alongside gaps in social cognition, rather than explaining them. Although both cognitive theories have their strengths and weaknesses, both have contributed to the understanding and treatment of ASD. Nevertheless, both theories lack the ability to be generalized, this is due to the concept that ASD is a spectrum and it is difficult to generalize study results when each individual exhibits unique autistic traits. Therefore, both theories have reduced ecological validity, making them difficult to apply to the population. As for preference for theory, I prefer WCC. Indeed, it accepts that individuals with ASD can have central coherence unlike ToM which does not take into account individuals who have actually successfully completed false belief tasks...
