Researchers found that the children with autism are twice as fast as the normal children of their age in the sensitivity of motion.

Previously, researchers found that the autistic people have enhanced visual abilities with still images. Now, this is the first study to show that they are also highly sensitive to the motion.
In this study, researchers exposed the children to the brief video clips of moving black and white bars to check the ability of the children with autism to perceive motion and found that the “kids with autism, got much, much better—performing twice as well as their peers,’ said Jennifer Foss-Feig, a postdoctoral fellow at the Child Study Center at Yale University.
According to the researchers, this hypersensitivity to the motion may show the condition of autism and may explain why some patients of autism are sensitive to bright lights and loud noises.
“We think of autism as a social disorder because children with this condition often struggle with social interactions, but what we sometimes neglect is that almost everything we know about the world comes from our senses.
“Abnormalities in how a person sees or hears can have a profound effect on social communication,” Duje Tadin, one of the lead authors on the study and an assistant professor of brain and cognitive sciences at the University of Rochester, said in a statement.
“Overall, we report a pattern of motion perception abnormalities in ASD (Autism Spectrum Disorder) that includes substantial enhancements at high contrast and is consistent with an underlying excitatory/inhibitory imbalance,” Researchers wrote.
