Dispersion Of The Theory About The Stimuli And Autism Through This New Study

Autism is a condition or disorder that begins in childhood where it causes problems in forming relationships and communicating with other people. There has been little evidence which shows that autism is more likely from anomalous parenting practices. However, by the use of the principles of behavior analysis, it has demonstrated and explained that the behavior of a child with autism can improve by the changing the parenting practices.

Suppositions or hypotheses about the nerve cells of people with autism spectrum disorders do not depend on and respond to external stimuli. However, these speculations have been challenged with the new studies made by John Foxe, chair of the neuroscience department at the University of Rochester Medical Center and senior author of this delving in the journal Cerebral Cortex.

The neuronal unreliability theory says that with the brain's response to any repetitive stimuli like visual, audio, touch or anything that affects or touches the five senses, it has been assumed that it should be steady and consistent. It has been concluded by this theory that the brains of any individual with autism do not vary and continually change their perception of the physical environment and impairs cognitive and social development according to Psycnet.

According to Urmc Rochester, Foxe's theory along with his colleges does not seem to be plausible with the basis from the brain activity of children having autism spectrum disorder over decades of studying. Furthermore, their studies concluded that it involved functional MRI experiments, which measure changes in the blood oxygen levels in the brain.

Foxe, along with his colleges somehow constructed a new study involving 20 people diagnosed with autism spectrum disease and 20 people who will serve as healthy controls. These people are exposed to repeated visual stimuli while wearing a dense array of electrodes on the surface of their scalp to record their brain electrical activities according to UMRC.

The researchers then find out that no matter how the researchers measured the variability of the responses, brain responses in autism were as stable as those of the controls. As a steadfast for this conclusion that this was not just in the case of their visual system, their team assesses tactile inputs like repeated touches to the wrist of participants but once again it has been proved that no evidence or anything that increases the response variability in the individuals with autism based on the measures of their brainwave responses.

With the study resulting negative findings with regards to the people with autism, the authors has contended that this study has importantly contributed to the field of autism where understanding of the disease as well as to the families, friends, and caregivers of these people may somehow understand these people's frustrations and adds knowledge to how are they going to deal with the disease.
