A new study on children with autism, conducted by researchers at Vanderbilt University, finds many have trouble matching what they are seeing with what they are hearing.
Experts liken it to a poorly dubbed movie... one in which the lip synch is off.
How that affects their ability to communicate or socialize is unknown.
Dr. Max Wiznitzer, of UH Rainbow Babies and Children's Hospital says, "This study doesn't tell us what does this really mean on a day to day basis, out in the field, in the home, in the school."
Those studies are happening now. There is some evidence that autistic children outgrow this synchronization issue by their teens, but it could still have had an impact on their speech development.
